Issue/Introduction

Is an IPL needed after installing SYSVIEW to take the new release into account? 

Environment

 

 

Resolution

NO, an IPL is not needed after installing SYSVIEW.

If the ASIDs have to be increased, you may need to IPL. 

Increase ASIDs (Optional): 
When the SYSVIEW® Performance Management main address space is stopped multiple times, and ASID reuse is not used. 
- You can run out of address space identifiers (ASIDs).
- You might need to IPL your system to obtain more ASIDs.

To avoid having to IPL your system, use the following procedure to increase the number of ASIDs.

Follow these steps:
1. Access the RSVNONR in the member IEASYSxx of SYS1.PARMLIB.
2. Increase the RSVNONR size to accommodate the number of times you could start and stop address spaces that define a system linkage index (System LX) within the life of an IPL.

When running out of ASIDs, messages alert of the failed address space creation and to IPL to obtain more ASIDs.
