ABEND S0C1 WITH ZSAMX STC and ZSUR079I ZSAM SVC nnn message

Products

• Compress Data Compression for MVS

Issue/Introduction

The customer received a  S0C1 abend in the Compress address space with message :

  ZSUR079I ZSAM SVC 026 INTERCEPT AT 8F84DC98 DISABLED ONLY 

Environment

Release : 5.5

Component : Compress Data Compression

Cause

The S0C1 abend was a planned S0C1 when the required SVC that is allocated is no longer addressable. The message generated tells you what SVC was no longer available.

Sample

ZSUR079I ZSAM SVC 026 INTERCEPT AT 8F84DC98 DISABLED ONLY

 This message is advising the customer that the required SVC 026 is not available at the time required.

Resolution

Compress will store the "original" address of the utilized SVC in the job storage space and when it is required again the original address is utilized. The failure occurred because the customer altered the SVC address location utilizing a product that alters SVC address-ability dynamically (in this particular example STOPx37)

Compress will utilize the following dynamic SVCs:

ALL SVC REQUESTS FOR OPEN, CLOSE,   OPEN-J, CLOSE-T - STUBS TO ATTACH, OBTAIN, RDJFCB, SVC26

If utilizing a product like STOPx37 you must always start Compress after these types of products are completely initialized and active. If you plan on altering one of the SVCs noted, it is recommended to shutdown Compress until the SVC address has been refreshed, and then restart Compress. Do not dynamically alter these SVCs while Compress is actively processing data sets.

Results can be unpredictable and at the very least you will receive the S0C1 and the related ZSUR079I  messages.
