Issue/Introduction

A CICS application, using Datacom VSAM Transparency Option, gets AICA abends after having upgraded Datacom CICS Service Facility (CSF) from 15.0 to 15.1. No changes on VSAM Transparency nor on Datacom/DB side.

Environment

Release : 15.1

Component : DATACOM CICS SERVICES

Cause

There are two problems here:

1. CICS job has the sample DVVXTPR and not the production module. So Datacom VSAM Transparency passes this request to CICS File Control which gets FILE_NOT_OPEN.
2. The application programs fail to check error code of FILE_NOT_OPEN. So it loops on a START BROWSE causing the AICA.

None of the problems is related to the CSF code. The production DVVXTPR had been incorrectly saved on the CSF 15.0 load library, so when this library is replaced by the new one in CICS, the sample DVVXTPR is used.

Resolution

Correct the above problems:

1. Make sure that CICS is using the correct DVVXTPR table
2. Modify the application programs to check the FILE_NOT_OPEN condition
