The client normally does CICS warm start of their CICS region and all the application files under CA DADS Plus control are allocated to CICS. When the client does a CICS COLD start one of their application programs does not get allocated to CICS at startup time. This causes one of the applications running in the CICS region not to function properly.
The client sees the following message in the CICS startup messages
DADSP691 15:22:20 S3CICS 'FILE'='WCODF010' ALLOCATE AT COLD START OPTION = N.
When you place files under CA DADS Plus CICS control the user specifies how CA DADS Plus CICS should allocate and open the file during COLD, WARM and emergency restarts.
In the example below this client specified options that would not allocate or open the file TESTFILE when a CICS COLD start was done. See parameter
ALLOC/OPEN AT COLD START ===> N N
The WARM and EMER startups the client specified
ALLOC/OPEN AT WARM START ===> A N
ALLOC/OPEN AT EMER RESTART ===> A N
A (automatic) instructs CA-DADS Plus CICS to allocate the file according to its last status during the previous execution of CICS.
N the file will not be opened until first reference.
