Handling return codes

You need to place the return codes from the access control authorization routine in the EXPL field named EXPLRC1. The EXPLRC1 value affects Db2 processing.

About this task

Begin program-specific programming interface information.

EXPLRC1 must have one of the following values during initialization.

Table 1. Required values in EXPLRC1 during initialization
Value	Meaning
0	Initialization successful.
12	Unable to service request; don't call exit again.

Db2 does not check EXPLRC1 on return from the exit routine during termination. Make sure that EXPLRC1 has one of the following values during the authorization check.

Table 2. Required values in EXPLRC1 during authorization check
Value	Meaning
0	Access permitted.

On authorization failures, the return code is included in the IFCID 140 trace record.
