Issue/Introduction

As per z/OS Compatibility Matrix PTF RO94154 is required for z/OS 2.2 and 2.3.
However, I am currently running z/OS 2.2 without this PTF without any problem and would like to upgrade to 2.3.
Do I have to install this PTF before upgrading to z/OS 2.3?

Environment

Release: SMV3EN00200-12.6-Graphical Management Interface
Component:

Resolution

This PTF is required for symbolic names and/or values longer than 8 characters, which was introduced with z/OS 2.2.
As long as the new symbolic format is not used, the PTF does not need to be installed.

Please note the following from the description of the PTF:

This sysmod supports the new limits for SYMDEFS on z/OS 2.2 as        
follows:                                                              
                                                                      
-  Symbolic name length limit is 16 characters (including '&' and     
   '.' 18 characters)                                                 
-  If the symbolic name ends with '_', the value length limit is 44   
   characters.                                                        
-  If the symbolic name does not end with '_', the value length limit
   is 16 characters.
