Environment variables in alphabetical order

C

CASSPOOL_LOCK_RETRY_COUNT
Category: JES
If errors are experienced by the spool module, the number of times it retries to obtain a record lock can be adjusted using this environment variable.

Syntax

SET CASSPOOL_LOCK_RETRY_COUNT=count

Values

count The number of retries made to obtain a record lock.

Default

If not specified, this variable defaults to 20.

CCITIMEOUT

Allows the specification, in tenths of seconds, of the maximum time out period that will be used with any LSC style application, such as Drag and Drop, SourceConnect, or the Monitor. The maximum value that can be used is 2,147,483,647.

Syntax

SET CCITIMEOUT=value

Default

The default is 1200 (2 minutes).

Example
This example sets the value to 4 minutes:
SET CCITIMEOUT=2400 
CCIERRLOG
Specifies the output location and filename of ccierr.log content which tracks first-instance errors reported from the operating systems. CCIERRLOG overrides any entries found in CCI.INI, where the syntax and content is explained in detail.
CCITCP2
Instead of using the CCI Configuration Utility to set the TCP address of the machine running the CCITCP2 registration daemon the environment variable "CCITCP2" can be used instead. This may be useful if you need different processes on the same machine to contact different registration daemons.

Syntax

set CCITCP2=hostname

Parameters

hostname is the TCP hostname or dotted decimal IP address of the machine running the CCITCP2 daemon you wish to contact from that session.

Comments

The environment variable value will always take precedence over any value set using the Configuration Utility. To restore a process to using the value set by the Configuration Utility simply set the environment variable to an empty string, such as

set CCITCP2=

Alternatively, if this environment variable is set system-wide (by creating a system variable in the system environment settings, or by using a CONFIG.SYS file) then this value will always take precedence over any value set using the Configuration Utility.

CCITCP2_PORT
The port that is being used for the registration process.

Syntax

set CCITCP2_PORT=port
Parameters
  • port The port on which the CCITCP2 registration program operates.
CCITCPS
To start a CCI server on a fixed port, you can associate the Server Name with the port value by using the CCITCPS_ environment variable instead of appending the information on the Server Name itself.

Syntax

set CCITCPS_server_name=port

Parameters

  • server_name is the name of the CCI server
  • port is the fixed TCP post to use

Note that this will only work if the server application process is started in the same session or process that has this environment variable set.

Example

set CCITCPS_server_name=MFPORT:3000
CCITCPT

If a client is known to be trying to connect to a server with Server Name server_name, and the TCP address and port (e.g. 3000) that the server is using is known, then the client can be made to connect directly to it by setting this environment variable.

Syntax

CCITCPT_server_name=MFNODE:server_hostname,MFPORT:port_number

Note that this can be used instead of setting the client Machine Name value. This is useful if the Machine Name value the client specifies cannot be altered by an application defined method.

Parameters

  • server_name The server to which the client is trying to connect.
  • server_hostname The TCP address.
  • port_number The TCP post number.

Example

CCITCPT_server1=MFNODE:server2,MFPORT:3000
CCITRACE
Part of the process to enable CCI tracing is to specify the degree of information that will be traced, which can be done by setting the CCITRACE environment variable as follows:

Syntax

CCITRACE=filename [options]
Parameters
  • filename The name of the log file you want the trace output to go to. If you do not specify this parameter, the log file ccitrace.log is created in the current directory with all options set to their default states.
  • options Any, or all, of the following:
/F or -F logs the details of CCI API calls to the trace file. The default is OFF, unless a filename any other trace option is specified, in which case it is always ON.
/P or -P logs the details of protocol-level calls to the trace file. The default is OFF. If this flag is OFF, then only the details of the CCI user-level API will be traced. If this flag is ON, the level of function tracing may be greatly increased.
/D or -D logs the contents of all buffers passed to and from the CCI functions. The default is OFF. Data tracing may not be allowed if the application has been coded to prohibit data tracing for security reasons.

So to create a CCI trace file with the default name of ccitrc1.trc (with matching ccitrc1.idx file) which traces CCI API function flow, along with the underlying protocol function flow, but with no tracing of the user data passed to these calls, the value of the CCITRACE environment variable would be /P.

The CCI.INI file can also be used to control trace options, but any values specified by the CCITRACE environment variable will take precedence.

CICS_SIT
The name of the SIT used by the region.
Values
  • The name of the SIT that the region uses.
COBCONFIG

Specifies a run-time configuration file that tailors the run-time configurable options in some way.

Syntax

SET COBCONFIG=pathname

Parameters

  • pathname The name of the COBOL configuration file that tailors the runtime

Comments

If $COBCONFIG is not set then the file $COBDIR/etc/cobconfig is searched for instead.

Example

SET COBCONFIG=/home/mydir/cobconfig
COBCONFIGJVM
Specifies a Java properties file that tailors the run-time configurable options for Java Virtual Machine applications. Use this instead of COBCONFIG in COBOL applications intended for use on a Java Virtual Machine.

Values

  • The location of a properties file.
COBCONFIG.BLOCK
The location of the application configuration file.
COBCPY

Specifies the directory or directories that the Compiler and Animator should search for copyfiles.

Syntax

SET COBCPY=pathname[:pathname]...

Parameters

  • pathname

    A directory that the Compiler and Animator are to search when looking for copyfiles. When more than one pathname is present, a null pathname represents the current working directory.

Example

SET COBCPY=/home/group/sharedcopy::mydir/mycpy

causes the Compiler to search for a copyfile in /home/group/sharedcopy, then in the current directory and finally in ./mydir/mycpy until either the copyfile is found or it can be considered not found.

COBDATA
Specifies one or more locations, separated by ; (Windows) or : (UNIX), in which to search for data files at run time. As long as the file assignment does not contain a sub-path (that is, a string containing \ or /) then the file assignment is appended to each location specified by COBDATA in order to locate the file.
Note: Users modernizing RM/COBOL or ACUCOBOL-GT legacy code can use a sub-path in the file assignment, but only by compiling with the relevant DIALECT or IDXFORMAT values for the respective File Handling systems; setting these values in the File Handling configuration file is not sufficient to achieve this.

Specifies the directory or directories that the run-time system is to search for data files. Provides you with the facility to map data files globally, thus enabling you to put working data files in a directory whose name is not known until run time.

Syntax

COBDATA=pathname[:pathname]...
Parameters
  • A list of search directories, each item separated by a semicolon. The runtime system is to search these when looking for application data files. When more than one pathname is present, a null pathname represents the current working directory.

Comments

COBDATA affects the compiler and other utilities. During compilation, for example, program source is regarded as a data file by the compiler. If you intend to use any COBOL development system utilities, we recommend that the COBDATA value starts with a colon (:).

COBDATA is considered set if there is an environment variable of this name in your environment space, and its value is non-empty.

The full mapping order for files is:

  1. Any dd_ environment mappings
  2. Any ASSIGN TO EXTERNAL mappings
  3. Any COBDATA environment variable mappings

For multiple directory paths specified either in the COBDATA environment variable or a dd_ environment variable, the system searches the first directory specified followed by a slash (/) as a prefix to the user name.

If the filename is not found, or is not readable, the search continues with the next directory until the final directory has been searched. If no file is found, the first directory is used if a file is to be created.

Any dd_ and COBDATA mappings are ignored for any filename that starts with a hyphen () or a slash (/). In addition, it is illegal to have a hyphen in an environment variable name.

When using this facility, you should not use a filename that starts with "COB... "(these are reserved for the COBOL system).

You can use the COBDATA environment variable for files open in any mode (including OUTPUT) and for fixed or variable length files. If you are using indexed files, both the data and index files must be in the same directory.

The COBDATA environment variable affects file deletes, using the rules given here, as well as file opens.

If you intend to use COBOL development system programs, we recommend that you first unset COBDATA, as many of these programs open data files and are thus affected by the value of COBDATA. If you have to set COBDATA, you should include the paths :$COBDIR/dynload/helptbox.lbr and :$COBDIR/dynload/check.lbr at the beginning of the COBDATA value. If you want to see the Animator Help pages, also include COBDIR/dynload/advanim.lbr.

Note: Users modernizing RM/COBOL or ACUCOBOL-GT legacy code can use a sub-path in the file assignment, but only by compiling with the relevant DIALECT or IDXFORMAT values for the respective File Handling systems; setting these values in the File Handling configuration file is not sufficient to achieve this.

Example

SET COBDATA=:demo:/home/data:progs

causes COBDATA to be set to instruct the runtime system to search for data files in the current directory, then in the directory ./demo, then in the directory /home/data and finally in ./progs.

COBDIR

Specifies the directory where the required Micro Focus COBOL system is installed. Many of the COBOL system components and utilities require and use this information. If the COBDIR environment variable is not set then the COBOL system acts as if it had been set to the default COBOL system directory.

Syntax
SET COBDIR=pathname

Parameters

  • pathname The directory that contains the required Micro Focus COBOL system software.

Comments

The Micro Focus COBOL system is normally installed in the default COBOL system directory and so does not require COBDIR to be set. COBDIR only needs to be set when your COBOL system has been installed in a different directory such as when more than one version of the COBOL system is available at the same time.

Example

SET COBDIR=/home/products/cobse20

This causes the Cob utility to search the directory /home/products/cobse20 for the Micro Focus COBOL system software.

COBJVM

Specifies which Java Virtual Machine (JVM) to load.

Syntax
SET COBJVM=platform_nnn

Parameters

platform_nnn where

platform is a threecharacter code that indicates the platform on which you are running Server Express, for example:
  • ibm IBM AIX
  • unx SCO UnixWare
  • sun Oracle SPARC
nnn indicates the version of the JVM, for example:
  • 122 Version 1.2.2
  • 130 Version 1.3.0

Comments

You might need to set COBJVM if you are developing distributed applications with both COBOL and Java components.

Example

SET COBJVM=ibm_122
COBKEYTIMEOUT

Specifies the maximum elapsed time, in tenths of a second, for the connected terminal to transmit any valid escape sequence to the runtime system.

When a terminal key is depressed, the terminal might send in response a single character or a group of characters to the runtime system. Typically, such a group of characters starts with an escape character and the group of characters is known as an escape sequence. A terminal might send an escape sequence for one depression of a function key. It might also send the same sequence of characters for a depression of the Escape key followed by the depression of one or more alphabetic or numeric data keys. The only difference apparent to the runtime system is the interval between the arrival of each character; the user cannot type as fast as the escape sequence is generated by the terminal.

If a terminal is connected over a network that sends the characters to the runtime system in discrete packets, then the network can alter the intervals between each character arriving at the runtime system. COBKEYTIMEOUT is available to help compensate for typical network delays so the runtime system identifies escape sequences correctly.

Syntax

SET COBKEYTIMEOUT=n

Parameters

n A number in the range 1 through 126 that represents the maximum elapsed time required for a terminal to transmit any valid escape sequence to the runtime system over the line or network connection. On encountering a lone Escape character, the runtime system waits n tenths of a second before assuming that the character does not introduce an escape sequence. The runtime system calculates an appropriate default value for n from the baud rate of the terminal.

COBLANG
The language environment in which your COBOL program runs.
Values
  • A COBOL language environment (LE) value.
COBLPFORM
This configuration variable is used to define and print to printer channels C01-C12. Specify the line numbers for each channel with the COBLPFORM configuration variable. Null entries are ignored. Those channels that have line number zero, function-names S01-S052, CSP, or are undefined, are set to line 1.

Example 1:

COBLPFORM 1:3:5:7:9:11:13:15:17:19:21:23

In this example C01 equals 1, C02 equals 3, and so on.

Example 2:

COBLPFORM :3::5: :9

In this example, C01 equals 3, C02 equals 5, C03 equals 1, and C04 equals 9. You can specify only a single line number for each channel.

In example 2 above, channels C05 - C12 are undefined. If a print statement specifies channel C05 - C12, the line is printed at line 1. In addition, in the example shown, C03 equals 1 because its value is a space and therefore undefined.

Any WRITE BEFORE/AFTER PAGE statements cause positioning to be at line 1. Each line advance increases the line number by one. A request to skip to a line number less than or equal to the current line causes a new page to begin. The appropriate number of line feeds are then generated.

COBMAINSTACK

Specifies the size of the main stack.

Syntax

SET COBMAINSTACK=n

Parameters

n A number in the range 1 through nnn that represents the size of the main stack.

Comments

You might need to set COBMAINSTACK in any of the following circumstances:

  • If you are deploying OO COBOL Enterprise JavaBeans (EJBs) to WebSphere on the AIX platform
  • If you are using the multi-threaded run-time system

    If you have IF STATEMENTS with a very large number of ELSE clauses

COBPATH

Specifies the directory or directories that the runtime system is to search for dynamically loadable .int and .gnt files, or callable shared objects.

Syntax

SET COBPATH=pathname[:pathname]...

Parameters

pathname A list of search directories, each item separated by a semicolon, that the runtime system is to search for a dynamically loadable program (.int, .gnt or callable shared object) file. When more than one pathname is specified, a null pathname represents the current working directory.

Example

SET COBPATH=u:/home/mydir/srclib:otherlib
COBPRFDIR
Location of .ipf files created by programs compiled with the PROFILE compiler directive.
Values
  • A list of search directories, each item separated by a semicolon.
COBPRINTER

Specifies the name of a print spooler that is to receive, via its standard input stream (stdin), output from any DISPLAY UPON PRINTER statement.

Syntax

SET COBPRINTER=command-line

Parameters

  • command-line A command line supported by your system and that can be executed by the system shell. Typically, it is simply the name of a print spooler or other executable, but if the shell is escaped when setting the value then any command-line arguments can be used.

Comments

Each DISPLAY UPON PRINTER statement executed by your COBOL program causes a new invocation of command-line. Each invocation receives the data referenced in the DISPLAY statement, and is followed by a system end-of-file condition.

Example

SET COBPRINTER="myspooler -a $TMPDIR\spoolfile"
COBSSL
If using SSL connections specifies the location of the DemoCA directory. If not found, SSLDIR is inspected instead.
COBSW
Specifies the run-time system switch settings for the run-time system to observe when running an application.

Syntax

SET COBSW=[+/-}s...
Parameters

A list of the runtime switches to set or unset.

  • + sets a switch.
  • - un-sets a switch.

Example

SET COBSW=+0+D

This enables runtime switch 0 and the ANSI COBOL debug switch.

Values

  • The location and name of the default database.
DBG_MVSPSKEL
The skeleton JCL for debugging.

E

ENTRYNAMEMAP
Specifies the locations of entry name map files to be used.

Syntax

SET ENTRYNAMEMAP={filename|directory}; ...

Parameters

filename An entry map file.

directory A directory containing an entry name map file. The name of the entry name map file must be mfentmap.dat.

Comments

You must set the entry_name_mapper tunable to enable entry point mapper support.

If ENTRYNAMEMAP is not set, the runtime system searches for an entry name map file called mfentmap.dat in each folder specified by the COBDIR environment variable.

If the runtime system finds more than one entry name map file and same entry point is defined differently in different files, precedence is given to the definition in the entry name map file that was found first. To change the order in which the runtime system finds entry name map files you need to change the order in which the files appear in the COBDIR or ENTRYNAMEMAP environment variable paths.

ES_ACBLIB
Specifies the locations of the IMS ACB files.

Syntax

SET ES_ACBLIB={pathname

Values

pathname The path location of the IMS ACB files.

Default

If this variable is not set the ACB files are assumed to be in the project directory.

ES_ALLOC_EXPAND
The default value is Y, which expands an environment variable when used to specify an allocation path. Set to N to override this behavior, which is to not expand the variable used in the path.

Syntax

SET ES_ALLOC_EXPAND=value

Values

Y Expands an environment variable used to specify an allocation path.

N Do not expand the variable used in the path.

Default

The default value is Y.

ES_ALLOC_OVERRIDE
The default value is Y, which expands an environment variable when used to specify an allocation path. Set to N to override this behavior, which is to not expand the variable used in the path.

Syntax

SET ES_ALLOC_OVERRIDE=rules-file

Values

rules-file The file path and name of the dataset rules file.

ES_CATLG_DISABLE_ADDITIONAL_QUAL

Set ES_CATLG_DISABLE_ADDITIONAL_QUAL=Y to make catalog searching and filtering more consistent with the results produced on the mainframe.

Syntax

SET ES_CATLG_DISABLE_ADDITIONAL_QUAL=value

Values

N enables the use of additional qualifiers. That is, implied qualifiers added to the end of your filter; for example, a filter of A.B would return the same results as a filter of A.B**.

Y disables the use of additional qualifiers, so when using the above example, a filter of A.B would only return a dataset of A.B. This option emulates the effect of disabling the 'Include Additional Qualifiers' option on the mainframe.

Default

The default value is N.

ES_CERT_REG
Specifies the directory in which the cascertreg user certificate utility should store its registrations.
Syntax
SET ES_CERT_REG=pathname
Values

pathname Pathname of the directory where registrations are stored.

Default

By default no directory is specified. In this case it must be specified on the cascertreg command.

Syntax
SET CESN_NO_OS390=value
Values
  • Setting this variable to any value causes CESN to produce an invalid credential message instead of a specific invalid user or invalid password message.
Default

Specific invalid user/password messages will be produced.

Values
  • Y or y Having logged on to ES administration via your MFDS internal security account, you no longer receive the auto logon as "mfuser" when accessing ESMAC.
Default
If this is not set, mfuser will be used as the default user to sign in to ESMAC.
ES_DFS3650
The default transaction to execute or MOD file to be displayed after successfully signing on to IMS. You specify these by setting environment variables prior to the start of the region: ES_DFS3650 - set to MOD if a MOD file is to be sent, or TRX if a TRANSACTION is to be executed. If you set to MOD, ES_MOD3650 needs to be set to the name of the MOD you want to display. If you set to TRX, ES_TRX3650 needs to be set to the name of the transaction.
Syntax
ES_DFS3650=value
Values
  • MOD - ES_MOD3650 needs to be set to the name of the MOD you want to display
  • TRX - ES_TRX3650 needs to be set to the name of the transaction
Default
No default transaction or MOD.
ES_ECI_MAX_RESP
Specifies the maximum expected response size (in bytes) to use when using Micro Focus ECI support to invoke CICS programs. You need to use this environment variable when the amount of data returned from the CICS programs is approximately more than twice the size of the input data, which is sometimes the case when using channels and containers where the back-end program creates or enlarges containers.
Syntax
ES_ECI_MAX_RESP=value
Values
  • Maximum value is 16777215.
Default
If this is not set, the maximum expected response size is calculated dynamically by multiplying the size of the TIOA by 2.
ES_ESM_CMDSEC
Indicates whether CICS processing honors the CMDSEC option specified on a transaction's PLT definition.
Syntax
ES_ESM_CMDSEC=value
Values
  • YES - CICS overrides the CMDSEC option, and always calls its command security checking routine to issue the appropriate call to the SAF interface
Default
CICS honors the CMDSEC option defined in a transaction's resource definition. CICS calls its command security checking routine only when CMDSEC(YES) is specified in a transaction resource definition.
ES_ESM_IDPW_CASE
Forces the case of user ID and password for single attempt ESM authentication. You use the environment variable with a format ES_ESM_IDPW_CASE=xy, where "x" is the folding option for user ID, and "y" the option for password.
Syntax
ES_ESM_IDPW_CASE=xy
Values

Values for both x and y are:

  • U - Always upper case.
  • L - Always lower case.
  • M - Mixed case and case sensitive

Default

Legacy behavior.

Comments

When this environment variable is set, Enterprise Server will only make one attempt to identify a user presenting the user ID and password as is (M), folded to uppercase (U) or folded to lower case (L). If this environment variable is not set, the legacy Enterprise Server behavior will be used.

For the legacy behavior for CICS, the User ID and the password are used as supplied possibly filtered by the uppercase translation configuration of the sign-on transaction.

For ESMAC and IMS, the legacy behavior is that, first, the user ID and password are used as supplied. If the authentication fails, the user ID is folded to uppercase and used again. If this fails as well, both the user ID and the password are folded to uppercase and then used.

Example

ES_ESM_IDPW_CASE=UM - a single authentication is tried with the user ID folded to uppercase, and the password used as-is.

ES_ESM_PLTPISEC
The level of security checking for PLTPI processing.
Syntax
ES_ESM_PLTPISEC=value
Values
  • NONE - You do not want any security checking on PLT initialization programs.
  • CMDSEC - You want CICS to perform command security checking only.
  • RESSEC - You want CICS to perform resource security checking only.
  • ALL - You want CICS to perform both command and resource security checking.

Default

NONE

ES_ESM_PLTPIUSR
The user id under which PLT programs run during CICS initialization.
Syntax
ES_ESM_PLTPIUSR=userid
Values
  • userid - The userid that CICS is to use for security checking for PLT programs that run during CICS initialization.
ES_ESM_RCF
Determines how RACF is used for command authorization

ES_TMC_AGGREGATE
Controls the performance environment for IMS TM data stores.

Syntax

SET ES_TMC_AGGREGATE={[,N|,D]|nnn,Y}

Values

,N
Sets the default behavior, which is to unilaterally flush operating system buffers to your physical disk at each key transactional point. While this does not change the method used by default at startup, it does enable dynamic modification via ESMAC. Once set, you can then test the effect of various non-default settings by altering them dynamically.
,D
Disables the transactional flushing of operating system buffers to disk. This option can significantly enhance message queue performance; however it is at the expense of the transactional integrity of the message queue in the event of a system failure.
Note: To avoid unpredictable results when using this setting, we highly recommend that you also set the static options as follows on the Administration Server > Properties > MSS > IMS > TM > General tab:
  • Set Cold start to Everything (queue)
  • Check Persist

See Server Instance Properties: MSS IMS TM General for details.

nnn,Y
Enables the aggregated transactional flushing of operating system buffers to disk where nnn represents an interval of time, in milliseconds, during which additional buffers are allowed to accumulate before flushing. Valid values are 0 through 255.

Once a thread reaches a key transactional point and requests a flush, TM waits the specified interval to accumulate subsequent threads that also request a flush. At the end of the interval, one flush is performed for all accumulated requests thus potentially improving performance by reducing the number of flush commands issued to the operating system.

Note:
  • Threads requesting a flush wait until the flush is confirmed.
  • Generally, when the message queue resides on a higher performance I/O subsystem such as one using SSDs, a smaller value, e.g. 1 or 2, produces the best results. A value of 10 or higher seldom improves performance.

Default

,N

MF_ALIAS
Specifies program aliases. Each set (pair) is 16 characters long - 8 characters for the program-name, and 8 characters for the alias. You can specify up to 10 pairs. This list is searched first and thus can potentially override the built-in list. If not found, the built-in alias table is searched.
MF_AMODE31ONLY
Indicates that all programs are AMODE(31).
MF_CBLQDA
Determines if QSAM files are dynamically allocated when processing an OPEN I-O or OPEN EXTEND statement for an optional file (that is, a file opened using the SELECT OPTIONAL syntax in the FILE-CONTROL paragraph) or a file opened for OUTPUT (regardless of whether it is optional or not). Permissible values are OFF and ON; the default is OFF, which specifies that dynamic allocation is not permitted.
This is an emulation of the CBLQDA Language Environment (LE) run-time option.
When set to ON, and your JCL contains a misspelled or no DD statement for the file being opened, a temporary file is created as a result of the OPEN statement, and then deleted after the program has run. For optional files opened for I-O or for EXTEND, you receive a return code of 05; for files opened for OUTPUT, you receive a return code of 00.
This variable has no effect on VSAM applications or the JCL utility programs.
Note: For programs that use ESDS files and have this variable set ON, ensure that FILETYPE is set to 15 or 16; otherwise these files will be affected by the variable, and treated as QSAM files.

  • DLEJ - Logs audit information each time a step in a JCL job deletes a catalog entry
  • DLET,DLEJ - Logs audit information each time either an ESMAC/CAS utility or a JCL job step deletes a catalog entry
MF_MFA
Specifies what dataset catalogs are to be searched.
Values:
  • ALL - Search for datasets first in the local catalog, and if not found, on the mainframe (default)
  • RJSE - Search for datasets in the local catalog only. No mainframe is performed.
MF_MVSJOB
Sets the number at which a job starts and finishes.
MF_MVSJOB=<lower value>{-|+}<upper value>
Where:
<lower value>
Number at which a job starts. Contains 7 digits - for example, 0000001
-
Sets the values but only on the first startup of the region.
+
Reset the values to these new ones each time the region is started.
<upper value>
Upper job number. Contains 7 digits - for example, 9999999
For example:
set MF_MVSJOB=0000010+0000100
This resets the values to start with job number 10 and run through to job number 100. When the upper limit has been reached you receive a message:
All job numbers in the range 0000010:0000100 are in use
At this point you need to remove some jobs from the spool - you can use the spool housekeeping functions to do this.

This environment variable can be used to enable a 7-digit Job number limit. If the <upper value> mentioned is greater than 99999, then 6+ digit job number support is enabled. The maximum value that can be set is 9999999.

Tip: To revert to 5-digit job number support, set MF_MVSJOB=<low number>+<high number>, where high number is less than 0099999, and ensuring that the + sign is used to separate the low and high values.

If a value set using this variable is not valid, the default values of <0001000>{-|+}<0099999> are set.

MF_NEWSPACE
Indicates whether SPACE is required for NEW datasets.
MF_PCRENAME_LAX
When an MVS dataset is renamed, the associated physical file is normally renamed only if it is in the Default Allocation Dataset Location. Set MF_PCRENAME_LAX to Y to enable physical files in other locations to be renamed if the cataloged name is changed.
MF_NODD
Specifies what action MSS is to take at run time if a job step uses a file that has not been allocated.
MF_RCCF
Enables Remote Job Step Execution (RJSE).

PROCLIB
When set to ON and under a mainframe emulation, a file status of 37 is returned when you open an existing VSAM file for OUTPUT and the file has or previously had some data written to it, or if the file format is different from the file on disk. The default for this variable is OFF.

R

RANDOM
If using SSL connections, externally generated random data that is stored as a numeric value in the RANDOM variable will be inserted into the initial salt value used to generate temporary key pairs used in SSL hand-shaking. The RANDOM value will only form part of the initial salt value and is an aid to generating more randomness and not an essential requirement.

S

SORTCOMPRESS
Tells the system whether or not to execute a compression routine on each record to be sorted.

Syntax

SET SORTCOMPRESS=5

Parameters

5 This is the only value that you can supply. It allows for run-length encoding of sort records, resulting in much better performance when records contain multiple repeated characters.

Comments

This variable is recommended if the sort records contain many single repeated characters, for example, multiple spaces, as it can be very effective in improving memory usage and therefore sort performance.

Example

SET SORTCOMPRESS=5
SORTSCHEME
Activates a sortscheme. Use in conjunction with SORTSPACE for improved performance.

Syntax

SET SORTSCHEME=1
Values
  • SORTSCHEME=1 - this is the only valid value for the environment variable. See SORTSPACE for more information.
SORTSPACE
The amount of memory to be allocated to internal workspace for SORT operations. This can be specified in different formats: for example, you could specify 64M, 2G, and 1000000 to give sort memory areas of 64 Megabytes, 2 Gigabytes and 1000000 bytes respectively.

Syntax

SET SORTSPACE=n[K|k|M|m|G|g]

Parameters

n[K|k|M|m|G|g The amount of memory to be allocated to internal workspace for SORT operations. K or k indicates kilobytes, M or m indicates megabytes and G or g indicates gigabytes. No letter indicates bytes. Defaults to 1 megabyte.

Comments

A larger value for SORTSPACE will generally result in a faster sort. However, if you specify a value that exceeds the capacity of main memory in your computer, such that the operating system has to page memory in and out, performance will be degraded.

Example

SET SORTSPACE=1024K

SORTTEMPSPACE
Specifies the amount of memory to be allocated to temporary workspace for SORT operations.

Syntax

SET SORTTEMPSPACE=n[K|k|M|m|G|g]

Parameters

n[K|k|M|m|G|g] The amount of memory to be allocated to temporary workspace for SORT operations. K or k indicates kilobytes, M or m indicates megabytes and G or g indicates gigabytes. No letter indicates bytes. 32 megabytes is the lowest amount of memory that can be allocated.

Comments

The memory allocation strategy used by SORT can be adjusted through use of SORTTEMPSPACE, which generally improves performance in systems suffering from memory fragmentation.

Example

SET SORTTEMPSPACE=250MB
SORTTYPE
Defines the sort type.

Syntax

SET SORTTYPE=2
Values
  • SORTTYPE=2 Forces SORT to use the file handler, so that format modifications are picked up from the extfh.cfg file.
  • Not setting this variable means that SORT will try to use CBL_ routines to read and write files to improve performance.
Note: 2 is the only valid value for this environment variable.
SSLDIR
If using SSL connections, this value specifies the generic location of the system's OpenSSL directory.
