XCOMM0007E 08 58 XCOMAPPB ACB OPEN ERROR

Products

• XCOM Data Transport - z/OS

Issue/Introduction

Received message "XCOMM0007E 08 58 XCOMAPPB ACB OPEN ERROR" when starting the XCOM task.

Environment

XCOM Data Transport for z/OS

Cause

The VTAM codes included in the XCOMM007E message indicate:

88 (X'58')
Another ACB, already opened by VTAM, indicates the same application program symbolic name that this ACB does.
The system programmer might have assigned the same symbolic name to two application programs. This is valid 
only if the programs are not open concurrently. Possibly the system operator initiated your program at the wrong time.

8 (X'08')
One or more ACBs were not successfully opened. If the error condition indicated by the unopened ACB's ERROR field can 
be eliminated, another OPEN macroinstruction can be issued for the unopened ACBs.

Resolution

Make sure that the APPL used by the XCOM task is not being used by another application. This seems to have been a timing situation since they were able to start the task manually.
