Each IDMS CV that runs on a CPU must have its own unique CV number. If you are running CA IDMS as a database application tool separate from CA Dispatch in the target CPU, see your CA 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 CA Dispatch is running on. This includes all CA Dispatch systems and all CA 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
a. Towards the top of this member, verify that the SYSTEM statement is correct and that it points to the correct SYSTEM NUMBER (Typically SYSTEM 01) for the Dispatch region you want to modify.
b. The next statement you will see in this member is the CVNUM statement. This is the statement you will modify in order to change the CV number associated to this Dispatch region. As an example, if the CV number you want to use for this Dispatch region is 7, you would specify CVNUM 07 on this statement.
c. Save your change in this member.
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".
