When attempting to start the CADZSPLx address space we are receiving a CADD051E Cannot locate control block CADDSNT error.
This particular error indicates 1 of 2 things...
1. The first (but unlikely) possible cause for the error is if the CAS9/CAIRIM job that initializes the CA Dispatch SVC and loads the CADZSPLx environments related modules into memory was NOT successful prior to you attempting the startup.
2. Or, the second (and more likely) cause for this error would be that you are issuing a /S CADZSPLx command (Notice the "CADZ") instead of the required /S CADDSPLx command (Notice the "CADD").
You cannot issue a start/submit command for the CADZSPLx or the CADZSAPx tasks directly.
To bring up the CADZSPLx environment, you must issue the start/submit command for CADDSPLx. This submits the environments initialization routine that, when successful, will automatically/dynamically start the CADZSPLx related task(s).
So, if you see this error (Or a S052 abend) during start up, go back and issue the correct /S CADDSPLx command and you should be good to go!
