Issue/Introduction

Just upgraded a Datacom MUF to 15.1. At the very first start, it gets the following messages:

DB01900I - *VIRTUAL    IXX017,32K         TEMP WORK INDEX FOR SQL REQUESTS            
DB01900I - *VIRTUAL    TTM017,4M          TEMP WORK AREA FOR SQL REQUESTS 
DB01900I - *ZIIPTASK   1,33               # ZIIP TASKS,PERCENTAGE OF WORK             
DB00216E - ERROR IN SYSIN/SYSIPT DATA                                                 

Then it abends due to a U0004 abend code.

Environment

z/OS

 

Cause

The SYSIN contains an invalid/incorrect card

Resolution

The error:

DB00216E - ERROR IN SYSIN/SYSIPT DATA

and the related U0004 abend are, in this case, due to the following card:

DB01900I - EXPAND 4K,10              EXPAND RECS BUFFER SIZE, NO. BUFFERS
DB01909E -          * - ASTERISK POINTS NEAR ERROR
DB01920E - TOO MANY PARAMETERS

EXPAND card is no longer required since Datacom release 14.2, as it can be read on the "Release Comparison" matrix on Datacom 15.1 documentation:

Feature Release 15.1  Version 15.0  Release 14.2  Version 14.0
EXPAND     no             no             no            yes

Additional Information

The following note can be found on the Datacom 14.0 Release Guide:

Removed EXPAND from MUF Startup
The EXPAND option has been removed from the MUF startup and if specified, displays an ignored message.
