Each IDMS CV that runs on a CPU must have its own unique CV number. If you are running IDMS as a database application tool separate from Dispatch in the target CPU, see your IDMS DBA for a CV number reserve list.
CVNUMBER specifies the number of the central version associated with this IDMS system. As the SVC is delivered and installed, the CVNUMBER must be an integer in the range 0 through 31, and must be unique within the machine that Dispatch is running on. This includes all Dispatch systems and all IDMS systems.
A Dispatch regions CVNUMBER can be identified from the startup messages via the following startup message:
DC201001 V1 T1 IDMS CENTRAL VERSION ?? STARTED
Outline of the Instructions for changing the CVNUMBER
Additional Considerations:
It’s imperative that the DSEXUSR1 job end with RC=00 so be sure and check the output.
If for some reason the job ends with a non zero return code you must RESTORE the dictionary files from the backup taken in step 2 of the above outline.
You must correct the problem that caused the non-zero return code to be received, and then RERUN the DSEXUSR1 job.
If you attempt to start Dispatch after receiving a non zero return code in this job and fail to take the corrective actions outlined above, Dispatch will appear to be active but never fully initializes. This leaves Dispatch in a completely unresponsive state and it will have to be CANCELED.
- Basic information about the DSEXUSR1 job and the CV number can be found in the CA Dispatch 11.7 Installation guide on page 90 where we document "STEP 5 - Define Users and the Network".
- More detailed information can be found in chapter 3 of the CA Dispatch System Programmers guide in the section entitled "User Generation Reference Section" and more specifically, in the section where we document the "SYSTEM Statement".
