Issue/Introduction

Is it needed to run an IPL after installing SYSVIEW 16.0 to take this release into account? 

Environment

SYSVIEW 15.0 & 16.0 & 17.0 - z/OS supported releases - 

 

Resolution

NO, an IPL is not needed to install SYSVIEW 16.0 except if the ASIDs have to be increased. 

Increase ASIDs (Optional): 
When the CA 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.

So an IPL is NOT required unless running out of ASIDs. 

In this case a message alert of the failed address space creation and to IPL to obtain more ASIDs.
