Review the following considerations when you use the PWXUMAP utility:
If you run PWXUMAP utility reports against a PowerExchange instance that runs on z/OS, the user ID you specify for the utility must have read access to the schemas and map files on the z/OS system.
If you run PWXUMAP utility reports against a PowerExchange instance that runs on z/OS, the process takes exclusive locks on DTLCAMAP, DATAMAPS, and CCT files, even when the access to those files is read-only. This might cause access issues if other PowerExchange processes are running concurrently.
