Customizing the PowerExchange Logger JCL

The PowerExchange Logger for z/OS can run as a started task or a batch job. Informatica recommends that you run the PowerExchange Logger as a started task because it is long running. You must customize the PowerExchange Logger JCL for your installation and then copy it to a system PROCLIB library for started tasks.

PowerExchange provides sample JCL for the PowerExchange Logger. The XIZZZ998 cleanup job in the RUNLIB library, which runs during installation, moves the PowerExchange Logger JCL to the PowerExchange PROCLIB library.

The name of the PowerExchange Logger JCL member in the PROCLIB library is the value that you specify for the

PowerExchange Agent / Logger Prefix

field in the z/OS Installation Assistant followed by the letter L. Based on the default

PowerExchange Agent / Logger Prefix

value of PWX, the default name for the PowerExchange Logger JCL member in the PROCLIB library is PWXL.

The PowerExchange Logger JCL includes the following statements and parameters:

EXEC PGM=EDMLC000,PARM=’logger_id
[,BATCH][,,,smf_id
]’

Invokes the PowerExchange Logger.

The PARM
parameter can contain the following required and optional positional parameters:

logger_id: The PowerExchange Logger identifier that is specified in the LOGGER_NAME parameter in the EDMUPARM module options. PowerExchange uses this value to locate the PowerExchange Logger options in the EDMUPARM module.
BATCH: Optional. The option for running the PowerExchange Logger in batch mode to perform maintenance activities. Use this option only when you update the EDMUPARM module options or define or delete logs from the ERDS.
smf_id: Optional. For Post-Log Merge configurations, this value overrides the system SMF ID value that PowerExchange appends to the PowerExchange Logger ID to form the XCF group name.

Each PowerExchange Logger XCF group name must be unique within the sysplex.

By default, the PowerExchange Logger uses the SMF ID on the z/OS system where it runs. If this SMF ID value is not unique within the Post-Log Merge group, you can use this parameter to provide a unique SMF ID value.

The following example shows an EXEC card that uses a symbolic parameter, &SMFID, to override the system SMF ID:

//LOGGER EXEC PGM=EDMLC000,REGION=0M,TIME=NOLIMIT, // PARM='&LOGNAME,,,,&SMFID',ACCT=XXXX

Valid values are 1 through 4 alphanumeric characters in length.

JOBLIB or STEPLIB DD

Defines the LOAD library that contains the PowerExchange Logger load modules. This library must be APF-authorized.

EDMPARMS DD

Defines the user library, USERLIB, that contains the EDMUPARM options module that is associated with the PowerExchange Logger.

If you do not include an EDMPARMS DD statement in the JCL, or if you specify a library that does not contain the EDMUPARM options module, PowerExchange uses the JOBLIB or STEPLIB concatenation to get the Logger configuration options.

ERDS01 DD

Defines the name of the primary emergency restart data set.

ERDS02 DD

Optional. Defines the name of the dual emergency restart data set when DUAL is specified for the ERDS_LOG_MODE parameter in the EDMUPARM options module.

SYSPRINT DD

Defines the output data set for z/OS system messages.

EDMTRACE DD

Defines the output data set for the common services trace.

Include this DD statement only at the request of Informatica Global Customer Support.
