Running OER

OER is run by using standard JCL and control statements. You need to specify an EXEC statement and DD statements that define the input and output data sets in your JCL.

About this task

Cataloged procedures FPXAPC1, FPXAPC2, and FPXAPC3 are provided for OPC and OER. These procedures are extensions of the IMS supplied cataloged procedure FPUTIL. You can use these procedures to run the batch DEDB Pointer Checker after you run OPC or OER.

The following cataloged procedures are stored in the SHFPSAMP sample library, and can be used as follows:

FPXAPC1 to run OPC or OER with TYPRUN=RPT
FPXAPC2 to run OPC or OER with TYPRUN=FS
FPXAPC3 to run OPC or OER with TYPRUN=PTRALL

Tip: If you want to change the return codes of OER, you need to create the return code user exit routines.

Procedure

To run OER, complete the following steps:

Specify the EXEC statement in one of the following formats:
```
//name EXEC procname
```
where procname is the IMS-supplied IFP procedure FPUTIL or any other IFP utility supporting procedure.
```
//name EXEC PGM=DFSRRC00,PARM='IFP,dbdname,DBF#FPU0'
```
where dbdname is the DBDNAME associated with the DEDB.
