Configuring for a BPE-based DBRC environment

To activate Integrity Checker in an IMS™ online environment that has a BPE-based DBRC region, you must configure the members of the IMS PROCLIB data set. This step is required only when a BPE-based DBRC is used.

Procedure

Set up the BPE configuration parameter member.
Specify the DBRC user exit list member by using the EXITMBR statement in the BPE configuration parameter member. The BPE configuration parameter member is specified by the BPECFG= keyword in the DBRC procedure that is used for the BPE-based DBRC region in which you want to activate Integrity Checker.

You can skip this step if the EXITMBR statement for the DBRC user exit list member already exists.

The following example specifies the EXITMBR statement in a BPE configuration parameter member:
```
   
   #
   # User exit list PROCLIB member specification
   #
   EXITMBR=(member_name,DBRC) /* DBRC user exit list member */ 
```
For more information about the EXITMBR statement, see the topic "BPE configuration parameter member of the IMS PROCLIB data set" in IMS System Definition.
Set up the DBRC user exit list member.
Specify the Integrity Checker load module FABLBIN0 on the EXITDEF statement. The FABLBIN0 module must be specified as a DBRC Request exit in the DBRC user exit list member. The DBRC user exit list member is specified by the EXITMBR statement for DBRC in the BPE configuration parameter member.
- When you have two or more DBRC user exits, the FABLBIN0 module must be specified as the first member on the EXITDEF statement.
- Do not specify the ABLIM parameter on the EXITDEF statement.
The following example specifies the Integrity Checker load module on the EXITDEF statement:
```
   
   ********************************************************************
   * DBRC USER EXIT LIST PROCLIB MEMBER                               *
   ********************************************************************
   #-----------------------------------------------------------------# 
   # DEFINE a DBRC request user exit.                                # 
   #-----------------------------------------------------------------# 
   EXITDEF(TYPE=REQUEST,EXITS=(FABLBIN0),COMP=DBRC)
```
