CSA Key 8 Usage using SYSVIEW

Products

• SYSVIEW Performance Management
• NXBRIDGE - SYSVIEW/ENDEVOR

Issue/Introduction

Preparing for z/OS 2.4 which defaults to no longer support CSA Key 8 usage. It defaults the DIAGxx parmlib member to VSM ALLOWUSERKEYCSA(NO).

• Discovered the COMMON command will tell you how much CSA Key 8 storage is used.
• Discovered the VSMTRACK Command will tell you which address space is using CSA/ECSA and SQA/ESQA.

After seeing in VSMTRACK all the users of CSA/ECSA, you would have to select each one separately to see if they are using it as Key 8.

Is there a simpler method of getting the information on who is using CSA Key 8?
Can it be done in batch?

Environment

Release : 15.0 and later

Component : SYSVIEW

Resolution

An automated method of identifying a summary of the CSA Key 8 storage usage is not available in SYSVIEW. A manual method of using SYSVIEW commands to display this CSA Key 8 storage usage is provided.

Here is the manual method to help with identifying CSA Key 8 usage:

In SYSVIEW run the following commands:

1. SET ASID 1 (gets you started at the first ASID)
2. VSMTRACK DETAIL (this will provide you with a column called KEY that you can now SELECT on)
3. SELECT KEY =  8  (this will reduce the list to only those with Key 8 usage and hopefully that will be a smaller number to scroll through and identify)
4. ASID NEXT (this will scroll through the ASID list in order one at a time)
5. Repeat step 2 - step 4.

Note that this approach is for active ASID's. 

That is the best manual approach that might help some with this effort.
