WORKLOAD GROUPS disappearing issue

• SYSVIEW Performance Management

Issue/Introduction

You can face a situation when defined GROUPS are disappeared or otherwise not defined GROUPS are appearing after the COLD start of CA SYSVIEW. 

Here is an example: After the COLD start of SYSVIEW when use GROUPS command you may notice WORKLOAD GROUPS that wasn't defined in PARMLIB member(hlq.CNM4BPRM(GROUPS)) and if you use RELOAD command without specifying any parameters WORKLOAD GROUPS disappeared.   

Cause

The WORKLOAD definitions are dynamically built as long as at least one definition does not exist.  So the dynamically built definitions are as follows:

 

JOB     JOB.=        
OTX     OTX.=        
STC     STC.=        
TSU     TSU.=        
SYSTEM  SYS.=        
SYSVIEW STC.SYSVIEW  
        STC.SYSVAUX  
        STC.SYSVUSER 

 

 

Resolution

During the initialization of the main address space, logical group initialization is performed.  The GROUPS definitions are read from DATALIB (WARM start) or PARMLIB (COLD start). Once the user-defined definitions are built, SYSVIEW determines if any groups exist of type WORKLOAD.  If zero groups exist with type WORKLOAD, then the internal definitions are defined.

 

 

 

Additional Information

NOTE: If adding WORKLOAD GROUPS dynamically, use SAVE command, that will save them to DATALIB and make them available after product restart. Also, if changing the start type from WARM to COLD and start seeing default WORKLOAD GROUPS instead of expected, use RELOAD DATALIB command to get what is stored in DATALIB
