ECCRNAME Parameter

A name for the IDMS log-based ECCR.

ECCRNAME=eccrname

For the eccrname variable, enter an alphanumeric string from 1 to 8 characters long.

No default. However, the z/OS Installation Assistant generates an ECCR name that begins with the

PowerExchange Agent / Logger Prefix

value followed by IDLEC, for example, PWXIDLEC.

The IDMS log-based ECCR uses the ECCRNAME value for the following purposes:

The ECCR name for connecting to the PowerExchange Logger to write change data

The member name that joins the XCF group of the PowerExchange Logger

As part of the ECCR-UOW field in the control information for each change record written to PowerExchange Logger log files

This name must be unique within a PowerExchange Logger group.

If you change the ECCRNAME value, the ECCR cannot warm start from its last position in the change stream. You must cold start the ECCR. Also,

in-flight

UOWs might occur in the PowerExchange Logger log files. To clean up in-flight UOWs, use the PowerExchange Logger RESOLVE_INDOUBT command.

Informatica recommends that you use the same value for both the ECCRNAME parameter and the IDMS log-based ECCR started task name or job name. This practice allows you to easily identify the IDMS log-based ECCR when reviewing messages and data from the PowerExchange Logger.
