Currently our z/OS was upgraded from V1.3 to V2.2. After that our DB2 space monitor jobs(that use REXX to read DB2 catalog for sizes etc) started failing while reading a file using EXECIO. It looks like REXX module needs to be altered/changed to become compatible with z/V2.2.
Please advise if anybody else also faced similar issue and what could be the resolution. Any pointers here would be greatly appreciated.
That would depend on what the errror is and what caused it. You have given no information in that regard. Have you consulted the migration guides as to changes to relevant objects conserned? What have you done to fix the problem?
