Skeleton JCL for generating MSDB Dump Recovery utility JCL

Skeleton JCL for creating MSDB Dump Recovery utility JCL

The following figure is an example of a skeleton JCL for the MSDB Dump Recovery utility.

Specify $$IEFRDER where you want to insert the IEFRDER DD statement, and $$MSDBCP where you want to insert the MSDBCPn DD statements.

//MSDBRCV  JOB (#ACNT),MSGCLASS=A,CLASS=A
//        EXEC PGM=DBFDBDR0

The JCL is written in the input data set specified by the MSDBIN DD statement. The completed JCL statements are written in the output data set specified by MSDBOUT1 and MSDBOUT2 DD statements. These two data sets produce the same output data.

$$ statements for MSDB Dump Recovery utility JCL

The $$ statement is specified in the skeleton JCL, and will be replaced by necessary DD statements in the generated JCL. If the first and second columns of the skeleton JCL contain $$, the line is interpreted as a $$ statement. The $$ statements can be specified multiple times. If there is an error in the $$ statement, the error statement is ignored and the process is continued.

There are two types of $$ statements:

$$IEFRDER or $$stepname.IEFRDER

If you want to specify a job step name, specify stepname. An IEFRDER DD statement, with DSN= and DISP=SHR subparameters, will be inserted at this place.

This DD statement describes the log data sets that contain the IMS system log, which is used for the MSDB recovery operations. In a dual logging environment, if an error is detected in the primary log data set, the secondary log data set name will be set.

$$MSDBCP or $$stepname.MSDBCP

If you want to specify a job step name, specify stepname. An MSDBCPn DD statement, with DSN= and DISP=SHR subparameters, will be inserted at this place. n is from 1 to 4 when the IMS system to recover is an XRF complex, from 1 to 2 in other cases.

This DD statement describes the MSDB checkpoint data sets. The specification differs according to how you specify MSDB=. For details of specifying the MSDB= parameter, read JCL requirements.
