How to enlarge the SYSDIRL DDLDML dictionary area.
Release: All supported releases.
Run Unload-Reload on the SYSDIRL.DDLDML area, using subschema IDMSNWKU. The segment name used would be SYSDIRL. The DDLDML area is a stand alone area, so no cross area pointers to worry about. The rest of the steps would be the same as for any Unload-Reload.
