Issue/Introduction

During a very busy time on Mainframe system Solve Operations issued the message:

*** SOLVEOP - RAMDB SHORT OF STORAGE *** 

It then put many of the resources in the resource monitor into unknown status,

For example:

RMSTMS40 EXTENDED DISPLAY<UNKNOWN DUE TO RAMDB SHORT OF STORAGE>

Tried to select an alert message it displayed some text mentioning using command STARTSY once shortage was resolved. It then disappeared.

Tried to issue a RES on a number of resources that had status 'SHORT OF STORAGE' but this just changed status to UNKNOWN. CHK command did not achieve anything.

 

 

 

Environment

Release : 11.9

Component : SOLVE:Operations Automation for z/OS

Resolution

Check if your SOLVE/NetMaster regions running with a limited size (REGION=) or is there any JES Exit to limit the region Storage.

One additional thing you could do is  turn off Message Learning in EventView,  if it's on,   to help save some storage.

 

STARTSYS puts all the resources into UNKNOWN and then resolves their state,  and if the Storage condition had been relieved it would have returned the region to a working state.

 

To diagnose and resolve this issue instead or before restarting the Solve Operations region.

 

You could issue the following two commands on a timed basis

(Possibly every 30 minutes):

 

SH VARTABLES STATS

 (It will list a lot of variables, but most importantly it will show the storage usage).

 

SH BUFF

 (there are some messages at the bottom that display the current storage usage)

 

Another useful command is the SHOW XSTG

 

SH XSTG or SH XSTG=ALL can be used along side the SHOW BUFF
