Creating a sequential data set copy of the RCDS

The CICS® VR recovery control data set (RCDS) is the repository of recovery data that is used by CICS VR. For every CICS VR problem that you report, create a sequential data set copy of one of the three RCDSs and send it to the IBM® Support Center.

The IBM Support Center prefers you to use the IDCAMS REPRO utility to create a sequential data set copy of an RCDS. Use the sample job shown below as a model to create your own copy. The sample job uses IDCAMS REPRO to copy an RCDS (DWW.DWWCON1) to a new sequential data set (EXAMPLE.REPRO).

Before you begin: Ensure that the record length of the sequential data set is equal to the CI size of the RCDS.

Explanation
01
Specifies the job statement for the job.
02
Specifies that the IDCAMS program is run to create a copy of the RCDS.
03
Specifies where to place any messages that are produced.
04
Specifies the name of the RCDS that you want to copy. You need to copy only one of the three RCDSs.
05
Specifies the sequential data set into which that the contents of the RCDS are placed. After this job has run successfully, send a copy of this data set to the IBM Support Center.
06
Specifies the data set that contains the IDCAMS commands. You can either specify the name of a data set that contains the commands or include the commands in-stream, as shown.
07
Specifies that the REPRO command copies all records from the source data set, DWW.DWWCON1, to the target data set, EXAMPLE.REPRO.
