Configuring the IDMS Log-Based ECCR JCL

Configure the JCL for the IDMS log-based ECCR.

Use the following sample JCL in the RUNLIB(ECCRIDL) member:

//********************************************************************

PowerExchange inserts values for the &HLQ and &LOGGER variables based on information that you provide in the z/OS Installation Assistant.

The following table describes the PowerExchange-related JCL statements for the ECCR startup PROC:

Statement	Description
EXEC	Specifies the ECCR program, DTLCCIDL.
STEPLIB DD	Specifies the PowerExchange LOADLIB and LOAD libraries. If you capture change data from IDMS records that use Presspack compression, you must also specify the IDMS runtime libraries so the ECCR can use Presspack decompression during change capture. Specify the IDMS libraries as follows: If the ECCR runs APF-authorized , copy the standard IDMS runtime libraries, including the libraries that contain the DCTs and a valid DMCL, and APF-authorize the copies. Then specify these copies in the STEPLIB concatenation. If the ECCR does not run APF-authorized , specify the standard IDMS runtime libraries in the STEPLIB concatenation. You do not need to copy the libraries.
EDMPARMS DD	Specifies the name of the user library that contains the EDMSDIR default options module that is associated with the PowerExchange Logger. If you do not include an EDMPARMS DD statement, or if you specify a library that does not contain the options module, PowerExchange uses the STEPLIB concatenation to get the configuration options.
DTLCFG DD	Specifies the DBMOVER configuration file for PowerExchange, which contains some parameters applicable to the IDMS log-based ECCR.
DTLKEY DD	Specifies the PowerExchange license key file.
DTLCACFG DD	Points to the RUNLIB(ECCRIDLP) member that contains IDMS log-based ECCR options.
SYSIDMS DD	Include this statement only if you capture change data from IDMS records that use Presspack compression and you do not use the default DMCL named “IDMSDMCL.” This statement either points to a data set that contains your DMCL statement or specifies the DMCL inline. Use the following syntax to specify the DMCL inline: //SYSIDMS DD * DMCL=`name` /* Where `name` is a DMCL name up to eight characters in length.
DTLAMCPR DD	Specifies the data set that contains the capture registrations.
DTLMSG DD	Specifies the output data set for PowerExchange messages.
SR2INPUT DD	Specifies the DTLUCSR2 utility result files. These files contain information that is used to generate the SR2-SR3 internal table.
DTLLOG DD and DTLLOG01 DD	Specifies the output data sets for ECCR capture statistics.
EDMMSG DD	Specifies the output data set for IDMS log-based ECCR messages.
