Question:

Are CA Optimizer/II and CA SymDump/Batch compatible with the IBM USEZOSV1R9RULES(NO) parameter?

 

Answer:

Yes, CA Optimizer/II and CA SymDump/Batch compatible with the IBM USEZOSV1R9RULES(NO) parameter.

As per IBM setting parameter USEZOSV1R9RULES to NO causes GETMAIN and STORAGE OBTAIN behavior for user-region private area subpools that are both below and above the line to be implemented. Thus DQEs can be merged where possible.

For CA Optimizer/II and CA SymDump Batch it is recommended you apply RO20498.

Other than that there are no known problems using this parameter.
