Issue/Introduction

After the buffers were increased, CA 7 was restarted, but the Datacom started task failed. The job log showed:

DUMP TITLE=CA Datacom/DB PROD     Reason--Error 89(151)      
DTACOMUF:DB02406I - PXX END - INSUFFICIENT MEMORY    

 

Cause

A 6M region should be sufficient for the MUF startup job, which converts the CXX. However, if you have increased the size and length of the buffers specified in your custom DBMSTLST module, the new buffer size could prove to be very large, thereby requiring more memory than anticipated for the MUF startup job.

Resolution

Increase the MUF region size or memlimit with one of these two options to match the increase of the buffers:

Option 1:

If you have the SMFLIM parmlib in place to override the REGION= value, then change the SMFLIM parmlib.
This is an example of the values that were changed:

SYS1.PARMLIB(SMFLIMMN) -                

000025  REGION JOBNAME(region-job-name)                
000026  REGIONABOVE(500M) REGIONBELOW(8M)    
000027  SYSRESVABOVE(1M) SYSRESVBELOW(256K)  
000028  MEMLIMIT(25G)       

or 

Option 2:

If you currently have REGION=0M try specifying a region larger than 32M say 64M to increase the size of memory allocated above the line. Also check with your systems programmers that there is no upper site limit on the region size.
