| CHANGEMAN_ASGROUP
|
Specifies the name of the MFA Server address space group used to process all ChangeMan requests. The SERVERS sample defines an address space group named CGMQ that is shared by ChangeMan definitions. If you use both features of MFA Server it is possible, but not necessary, to create separate ASGROUP definitions.
The ASGROUP definition in the SERVERS member names a JCL procedure used to initiate the dependent region started tasks. MFA Server provides a procedure named MFAAS that serves as the basis for all dependent-region JCL procedures. You customize and add this JCL to a system procedure library during server installation. Some features of the MFAAS JCL procedure appear as JCL comment statements that you can customize yourself, including symbolic parameters and STEPLIB program library names. You can also customize any of several specialized ChangeMan DD statements in the procedure. The MFAAS JCL contains text that explains all required customizations for ChangeMan.
Specify the one- to four-character ASGROUP name to associate with ChangeMan processing. If you omit this parameter the address space group name defaults to CALL.
|
| CHANGEMAN_COMMON_BUILD
|
Specifies whether or not Mainframe Access accommodates group builds submitted under AppMaster Builder. Specify YES to enable group builds or NO to disable them. The default is NO. When enabled for group builds, MFA modifies the build options for each member of the AMB group to match the component name and type submitted, ensuring that each build request in the group is properly executed.
|
| CHANGEMAN_DSNQUALIFIER
|
Specifies a high-level qualifier for dynamically allocated data sets created by MFA Server to hold input files during the staging process. MFA Server creates these data sets dynamically as card-image sequential data sets that are deleted when the associated client request completes. The default qualifier is the login ID of the current user. You should set an alternate qualifier if your installation's SERNET does not have RACF authority to read or write data into files stored in data sets named with the current user's login ID as the high-level qualifier.
If an alternate qualifier is required, see your ChangeMan administrator or your security administrator for assistance in selecting a proper value.
If your ChangeMan functionality is restricted by security subsystem authorizations, you might need to specify your dataset high-level qualifier such that read access to the data sets is always permitted.
|
| CHANGEMAN_INTERFACE
|
Specifies the name of the ChangeMan ZMF module. During ChangeMan request processing, MFA Server loads and branch enters this module. Valid values are
SERXMLBC and
SERXMLAC. The default is
SERXMLAC.
The preferred interface module is SERXMLAC, which is not documented by Serena; however, it provides better interface performance than SERXMLBC by using virtual storage instead of data sets for XML input and output exchange between MFA Server (the requester) and ChangeMan ZMF.
Serena documents only the SERXMLBC interface, which is the XML services batch client. SERXMLBC is intended for use in a batch job stream and requires XMLIN and XMLOUT DD statements to define its required data sets. The MFAAS JCL sample provides sample DD statements for XMLIN and XMLOUT; however, they are commented out. If you must use SERXMLBC, contact SupportLine for assistance with data set definitions.
This parameter is required in both the PARMS member and the PARMSAS member used by application server address spaces.
|
| CHANGEMAN_SSID
|
Initializes the Mainframe Access ChangeMan interface by providing the final character of the z/OS subsystem ID used to identify ChangeMan. Omit this parameter to bypass Mainframe Access initialization for the ChangeMan interface. Valid values are any single alphabetic or numeric character. The character specified is appended to the subsystem ID string "SER", completing the four-character ID. For example, if you specify CHANGEMAN_SSID=A, the z/OS subsystem ID becomes "SERA".
This parameter is required in both the PARMS member and the PARMSAS member used by application server address spaces.
Your ChangeMan administrator can help you to determine the correct subsystem ID to use.
|
| CHANGEMAN_TEST_OPTION
|
Specify whether or not MFA uses the XML trace option. Specify YES to enable XML trace or NO to disable it. The default is NO. When enabled, SERNET logs information in XML format into the standard SERPRINT DD file. This file can be used to identify problems and to validate MFA services. Enabling XML trace is not recommended for production systems due to the large volume of log data generated.
|
| CHANGEMAN_XMS_SIZE
|
Specifies the size in megabytes of the cross-memory buffer used by MFA for transmitting XML requests and responses to the ChangeMan dependant Region. A single integer in the range of 1 through 7 is accepted. Note that about 2500 directory entries, or 10,000 lines of source code may be passed in 1 megabyte. If your requirements exceed these limits, then you can configure a more appropriate value. The default value with no configuration is 1 megabyte.
