Methods of Specifying and Updating Parameters

BMC PARMLIB

Code Debug CICS allows you to specify most configuration parameter values using BMC PARMLIB at product initialization.

Parameters are specified in BMC PARMLIB member XDGBxxxx.

Warning

The recommended best practice is to use the BMC PARMLIB for setting parameters. Assembling DBUGGBL is no longer supported. If your site previously assembled DBUGGBL to change transaction identifier for DBPA, XPED, XPRT, XPON, or XPSP, see Overriding-Session-Initialization-Transactions

Updating the CMSC with Your PARMLIB Members

If you have made changes to your PARMLIB members, you can use the z/OS MODIFY (F) command to update the CMSC with those changes.

Refreshing All PARMLIB Members

F cmscname,PARMLIB REFRESH

Refreshing a Single Parameter Member

F cmscname,PARMLIB REFRESH member_name

Important

During the refresh process, parameter values are validated. If they are found to be invalid, an error message is written to the FDBDLOG SYSOUT data set associated with the ECC CMSC instance where the member is being refreshed. If an error is detected, the contents of the in-core member will not be refreshed. You must correct the error and refresh the member before attempting to use it.

Updating the Code Debug CICS Parameters While CICS is Active

If you have made changes to your PARMLIB members while CICS is active, you can use transaction XSIT to update the active CICS region with those changes.

All parameter values can be updated by entering the transaction XSIT. XSIT directs CMSC to refresh the PARMLIB members for this CICS region. It then updates Code Debug in this CICS region with the parameters from CMSC.

If you execute XSIT while Code Debug is active, the following parameters will not be updated:

ACTIVATE_CODE_COVERAGE_AT_INITIALIZATION
CODE_COVERAGE_START_XPEDITER_NORMALLY
DYNAMIC_TRANSACTION_ROUTING_SUPPORT
ENABLE_DYNAMIC_FILE_DEF_FOR_SLS_FILES
ENABLE_GLOBAL_USER_SIGN_OFF_EXIT
ENABLE_UTILITIES_MODE
ESD_CACHE_BUFFER_SIZE
MAX_SUBTASKS_FOR_PDSE_SUPPORT
MAXIMUM_SLS_FILES_TO_SEARCH
MONITOR_MAX_STG_ABOVE_BAR
NUMBER_CONCURRENT_PDSE_REQUESTS
SERVICE_PROVIDER_SUBSYSTEM_NAME
SLS_DDNAME_TEMPLATE
SLS_DSN
SLS_SHARED_DATABASE_TEMPLATE
SUPPORT_CICS_OPEN_TRANSACTION_ENV
TRANSID_XPFS
USER_PROFILE_DDNAME.

Script Facility Parameters

The following parameters cannot be dynamically updated using XSIT while the Script Facility is active:

SCRIPT_FACILITY_SYSTEM_SCRIPT_DDNAME
SCRIPT_FACILITY_USER_SCRIPT_DDNAME

File Utility Audit Trail Parameters

The following parameters cannot be dynamically updated using XSIT while the File Utility Audit Trail is active:

FILE_UTILITY_AUDIT_TRAIL_ALLOC_TYPE
FILE_UTILITY_AUDIT_TRAIL_BASE_DSN
FILE_UTILITY_AUDIT_TRAIL_BLKSIZE
FILE_UTILITY_AUDIT_TRAIL_DDNAME
FILE_UTILITY_AUDIT_TRAIL_DELETED_RECORDS
FILE_UTILITY_AUDIT_TRAIL_ENABLE
FILE_UTILITY_AUDIT_TRAIL_NEW_RECORDS
FILE_UTILITY_AUDIT_TRAIL_NON_SMS_DSCB
FILE_UTILITY_AUDIT_TRAIL_PRIMARY_ALLOC
FILE_UTILITY_AUDIT_TRAIL_SECONDARY_ALLOC
FILE_UTILITY_AUDIT_TRAIL_UNIT
FILE_UTILITY_AUDIT_TRAIL_UPDATED_RECORDS
FILE_UTILITY_AUDIT_TRAIL_VOLUME.

Assembling DBUGGBL

Assembling DBUGGBL is no longer supported. If your site previously assembled DBUGGBL to change transaction identifier for DBPA, XPED, XPRT, XPON, or XPSP, see Overriding-Session-Initialization-Transactions.
