IMS SNAPQ dump

Products

• MICS Resource Management

Issue/Introduction

While running the LDE stand alone job (pgm=maldedrv), we had a S322 error supposedly due to:

 'What happened was that when the job was running,  the /CHE SNAPQ command had been entered by IMS.  IMS does this periodically to dump committed log records to the IMS message queues.  Apparently, there was a lot of work that needed to be committed, so the action took a while.  When this happens, everything in the region stops processing until the command completes.

Is there a way to bypass these dump records and process the 'normal' data?

Environment

Release : 14.1

Component : MICS

Resolution

There is no option in LDE to bypass the SNAPQ dump records. All data from the input file are processed, but those records that are not IMS log records or Mainview, are not selected for further processing. 

You can avoid S322 ABEND by coding TIME=MAXIMUM parameter on the JOB statement for the LDE stand alone job so that the LDE job can run for up to 357912 minutes.
