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 
CASSPOOL_LOCK_RETRY_COUNT=retry-count
Parameter
retry-count
The number of retries made to obtain a record lock.
Default 
CASSPOOL_LOCK_RETRY_COUNT=20

DBG_MVSPSKEL

ES_ALLOC_EXPAND

Expands an environment variable when used to specify an allocation path, or overrides this behavior.
Syntax 
ES_ALLOC_EXPAND={Y|N}
Parameters
Y
Expand the environment variable used to specify an allocation path.
N
Do not expand the variable used in the path.
Default 
ES_ALLOC_EXPAND=Y

ES_ALLOC_OVERRIDE

The location of a file containing rules that determine where new data sets are created. This applies only to JES and batch files, and not CICS, IMS, or Web services files.
Syntax 
ES_ALLOC_OVERRIDE=path-name/rules-file
Parameters
path-name
The full path to the dataset rules file.
rules-file
The name of the dataset rules file.
Default
Not set.

ES_CAT_RETRY_COUNT

Determines the number of attempts made to open a catalog file that has produced an error when the initial attempt to open it was made.
Syntax 
ES_CAT_RETRY_COUNT=attempt-count
Parameter
attempt-count
The number of attempts made to open a catalog file.
Default 
ES_CAT_RETRY_COUNT=0
Comments
Use this variable in conjunction with the ES_CAT_RETRY_WAIT variable, which determines how long to wait in between each attempt.

Take care when setting these variables as they could impact the time taken to report an error and therefore will delay processing of a job whilst the checks take place. These variables can be useful if you experience file access problems (for example, network connection drop-outs) that only last a second or two, so that it gives the system a chance to recover, before aborting.

ES_CAT_RETRY_WAIT

Determines the amount of time (in seconds) to wait between attempts made to open a catalog file that has produced an error when the initial attempt to open it was made.
Syntax 
ES_CAT_RETRY_WAIT=wait-time
Parameter
wait-time
The number of seconds to wait between attempts made to open a catalog file.
Default 
ES_CAT_RETRY_WAIT=0
Comments
Use this variable in conjunction with the ES_CAT_RETRY_COUNT variable, which determines how many attempts to make to open a catalog file that initially failed to open.

Take care when setting these variables as they could impact the time taken to report an error and therefore will delay processing of a job whilst the checks take place. These variables can be useful if you experience file access problems (for example, network connection drop-outs) that only last a second or two, so that it gives the system a chance to recover, before aborting.

ES_CLUSTER

Identifies a region as participating in an Enterprise Server cluster.
Syntax 
ES_CLUSTER=ON
Parameter
ON
Sets the region to participate in an Enterprise Server cluster.
Default
Not set. The enterprise server region does not participate in an Enterprise Server cluster.
Comments
Mandatory for all enterprise server regions in a cluster.

ES_CLUSTER_ISC_TRACE

Enables tracing on the Enterprise Server cluster ISC listeners.
Syntax 
ES_CLUSTER_ISC_TRACE=ON
Parameter
ON
Tracing of ISC listeners for an Enterprise Server cluster is enabled.
Default
Not set. Enterprise Server cluster ISC listeners are not traced.

ES_CLUSTER_LISTENER_PORT_TO_USE

Sets a specific port for an Enterprise Server cluster listener.
Syntax 
ES_CLUSTER_LISTENER_PORT_TO_USE=port-number
Parameter
port-number
The port number to assign to a cluster listener.
Default
Not set. The Enterprise Server cluster listener uses an ephemeral port.

ES_DSENQSHR

Enable and configure handling of the DSENQSHR keyword when it is specified on the JCL job card, and when it is not specified on the job card.
Syntax 
ES_DSENQSHR={ALLOW|AUTO|DISALLOW}
Parameters
ALLOW
For JCL jobs that have the DSENQSHR keyword specified on the JCL job card, sets DSENQSHR to the value specified on the job card. For jobs that do not have the DSENQSHR keyword specified on the JCL job card, sets DSENQSHR=ALLOW for each of those jobs.
AUTO
Use the value specified on the JCL Job card, which sets ES_DSENQSHR to ALLOW when that value is either ALLOW or USEJC, and DISALLOW otherwise.
DISALLOW
For jobs that do not have the DSENQSHR keyword specified on the JCL job card, sets DSENQSHR=DISALLOW for each of those jobs.
Default

When the job card does not specify the DSHQSHR keyword or when the job card sets DSENQSHR to USEJC: 

ES_CAT_RETRY_WAIT=ES_DSENQSHR=DISALLOW

When the job card specifies the DSENQSHR keyword, the value of DSENQSHR is used.

Comments
When DSENQSHR is allowed on a job, exclusive dataset locks are downgraded to SHARED after performing the last step that requires an exclusive lock.

Exclusive locks resulting from a dynamic exclusive enque (for example an IDCAMS DELETE operation) are maintained as exclusive until the end of the job regardless of the DSENQSHR setting.

Use VSAM Share options with VSAM datasets. You can enable these by setting the ES_SHAREOPT environment variable to Y.

ES_ELAPSED_DISPATCH_SECONDS

Specifies how frequently casmgr checks for Jobs in the waiting state and then starts them.
Syntax 
ES_ELAPSED_DISPATCH_SECONDS=wait-time
Parameter

ES_JES_BYTES

Maximum number of bytes to output in a job before taking the action specified by cancelling the job, cancelling the job and dumping memory contents, or issuing a warning message.
Syntax 
ES_JES_BYTES=(number[,{WARNING|CANCEL|DUMP}])
Parameters
number
Maximum number of bytes in thousands. The range is from 0-99999999.
WARNING
Issue a warning when the specified maximum number of bytes is reached.
CANCEL
Cancel the job when the specified maximum number of bytes is reached.
DUMP
Cancel the job and dump the memory contents when the specified maximum number of bytes is reached.
Default
Not set.
Example
In this example, each line is assumed to hold 132 bytes; therefore the job is automatically cancelled at 100000/132 lines, and the memory contents are dumped: 
ES_JES_BYTES=(100,DUMP)

ES_JES_CARDS

Maximum number of cards to output in a job before taking the action specified by cancelling the job, cancelling the job and dumping memory contents, or issuing a warning message.
Syntax 
ES_JES_CARDS=(number[,{WARNING|CANCEL|DUMP}])
Parameters
number
Maximum number of cards. The range is from 0-99999999.
WARNING
Issue a warning when the specified maximum number of cards is reached.
CANCEL
Cancel the job when the specified maximum number of cards is reached.
DUMP
Cancel the job and dump the memory contents when the specified maximum number of cards is reached.
Default
Not set.
Example
In this example, each card is assumed to hold 25 lines; therefore at 750 lines (25×30) a warning message is issued the job continues. 
ES_JES_CARDS=(30,WARNING)

ES_JES_CONSOLE_MESSAGES

Determines whether to lodge CASMG0001I messages in the splmsg.dat list for a job.
Syntax 
ES_JES_CONSOLE_MESSAGES={Y|N}
Parameters
Y
Lodges CASMG0001I messages in the splmsg.dat list for a job.
N
Does not lodge CASMG0001I messages in the splmsg.dat list for a job.
Default 
ES_JES_CONSOLE_MESSAGES=Y
Comments
CASMG0001I messages are produced when a program running in a JCL job does 'display upon console'. These messages, along with others, are lodged in the splmsg.dat file. When the job information is displayed in ESCWA/ESMAC, these messages are also shown.

There is a limit of 65535 messages per job. If that limit is exceeded, the last messages sent will overwrite the last message already lodged in splmsg.dat.

There is a way to work around this, if your program outputs a lot of messages. You can set ES_JES_CONSOLE_MESSAGES=N in order to avoid storing the messages in splmsg.dat. Whatever this setting, the CASMG0001I messages will still be included in the JESYSMSG for the job.

There is also a Job statement extension so that this can be configured on a job by job basis - see the line below. See JOB Statement Extensions for more details. 

//*MFE:%CONSOLE_MSGS=Y|N

ES_JES_DELAY_MEM_ENQ

Determines whether to delays the exclusive enque of a new (not previously existing) PDS member until the file is opened.

Comments

Setting ES_JES_FREE_SSTM_SYSOUT=Y helps to avoid problems with receiving out of memory errors when creating multiple new files.

CAUTION:
Setting the variable also removes the tracking information about the file which means that the file's status (SPOOLED) no longer appears in the JESYSMSG for the SSTM job.

ES_JES_HIGHER_SECURITY_LEVEL

Parameters
0
The behavior is unchanged with regard to JES enhanced security.
1|NONE
A value of 1 or NONE is the equivalent of not setting the value and maintains the behaviour of earlier versions of Enterprise Server. With a setting of 1 or no setting at all, warning messages about the number of SYS1.LNKLIB entries might be issued if none have been defined (JES000067W) and messages about programs not being loaded from certain locations (JES000069W) are also given. In addition, messages JCLCM0260W and JCLCM0308W might also be issued.
2|BASIC
A level of BASIC or 2 causes programs to be loaded from the list of SYS1.LNKLIB entries, STEPLIB, and JOBLIB locations. Programs in other locations are not loaded. The loading of programs from dynamic PDSs is also entirely disabled.
3|WARN
A level of WARN or 3 causes checks to be made against the PROGRAM and the PHYSFILE security classes. The PHYSFILE check is to make sure the PHYSFILE resource class is implemented. If these checks fail, a warning message (JCLCM0262W, JCLCM0263W or JCLCM0266W) is issued.
4|ENHANCED
A level of ENHANCED or 4 will cause the same PROGRAM and PHYSFILE checks to be made but if they fail then the job will abend with an S913 security error and a suitable message will be issued to indicate the failure.
Default 
ES_JES_HIGHER_SECURITY_LEVEL=1

SILENT
No messages. Use this option with caution, as it specifies that no audit log of your spool data sets is created.
Default 
JES_PRINT_SPOOL_MSG=CONSOLE
Comments
This environment variable is intended for high-print-load users, meaning that a high number of print requests are sent to the console. This could affect system performance.

MF_ALIAS

Specifies program aliases.
Note: You can alias any program other than IEFBR14, which is always processed as IEFBR14.
Syntax 
MF_ALIAS=program-name1 alias1 [program-name2 alias2]...[program-name10 alias10]
Parameters
program-name1...10
An eight-character program name.

upper-value
Upper job number. Contains seven digits - for example, 9999999.
Default 
MF_MVSJOB=0001000+0099999
Comments

This environment variable can be used to enable a seven-digit Job number limit. If the upper-value 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 five-digit job number support, set: 
 MF_MVSJOB=lower-limit+upper-limit

Where upper-limit is less than 0099999, and ensuring that the + sign is used to separate the low and high values.

Example
Resets the values to start with job number 10 and run through to job number 100: 
MF_MVSJOB=0000010+0000100

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.

MF_UCC11

Configures emulation of UCC11, which is the JCL job restart functionality.
Syntax 
MF_UCC11={Y|YA|M|MA|MR|N}
Parameters
Y
When restarting a job with DISP=(NEW,CATLG), it will not result in job failure caused by the data set already being cataloged.
YA
When running a job with DISP=(NEW,CATLG), it will not result in job failure caused by the data set already being cataloged.
M, MA, MR
When restarting a job any data set that has an inital disposition of NEW is changed to MOD. Therefore, data will be appended to the data set if it already exists.
N
MF_UCC11 is not set so a data set with an initial disposition of NEW might cause an error when restarting the job if the data set already exists.
Default 
MF_UCC11=N
Comments

This environment variable works independently of the JCL RESTART parameter.

The setting of the MF_UCC11 value can be made on a job-by-job basis using either the JCL user exit, MFJUXIT, or the Advanced Restart Functionality.

When set to Y or YA, if the job uses GDG data sets, the GDG generation is reset to the level used in the previous job, ensuring that the restart will automatically pick up the correct GDG generation.

GDG Restart information is usually only written when MF_UCC11=Y, YA or M and ES_JES_RESTART=Y. You can ensure that it is always written by setting ES_JES_RESTART=Y and GDG_RESTART_UCC11_ONLY=N - this will ensure that the restart information is available if a job is restarted at a later date.

When restarting a job with restart functionality enabled (that is, values Y, YA, or M), COND Code Processing and IF/THEN logic that is dependent upon COND codes from prior steps that are skipped by the RESTART, will work as expected with no changes to the JCL.

When set to YA or M and the disposition of the data set is DISP=NEW, if the DSORG of the data set is defined on the DD Card, it will be checked against the catalog record, if the latter exists. If there is a mismatch, or if the catalog record refers to a GDG base, the data set will not be replaced, and the JCLCM0200S error message is issued.

MF_UCC11_DYNCLEAN

When MF_UCC11 is enabled, controls whether dynamically allocated datasets (such as using SVC99) are cleaned when a job is restarted.
Syntax 
MF_UCC11_DYNCLEAN={Y|N}
Parameters

When a job is restarted, any dynamically allocated datasets are removed and replaced.
N
Prevents the cleaning of dynamically allocated datasets when restarting a job.
Default 
MF_UCC11_DYNCLEAN=Y
Comments
Depandancies are valid only when MF_UCC11=Y or YA.

MF_USESCA7

Comments
The default behavior of this product is to not check COND CODES from steps prior to a restart step. This means that the steps after the restart step that have conditions that refer to any steps prior to the restart step might run. This is a change of behavior from releases 4.0 Patch Update 1 and earlier when these steps would have not run. Micro Focus recommends that you review and test the behavior before restarting the jobs.

Set this variable to Y to prevent steps after a restart step that have conditions that refer to any steps prior to the restart from running.

The setting of MFJ_ALL_STEP_CHECK is bypassed if the Abend and Cond Code Recover option of the Advanced Restart Functionality is used.
