Control Region Startup Parameters

CHANGEMAN_COMMON_BUILD Specifies whether or not Mainframe Access accommodates group builds submitted under AppMaster Builder. Specify 1 to enable group builds or 0 to disable them. The default is 0. 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 (HLQ) 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 HLQ.

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 HLQ such that read access to the data sets is always permitted.

Note: As this specifies an HLQ, it must be limited to 8 characters in length.
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 in ChangeMan ZMF; 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.

ChangeMan ZMF 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 Customer Care for assistance with data set definitions.

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".

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 1 to enable XML trace or 0 to disable it. The default is 0. 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 8 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.
