The client is using the CA DADS Plus CICS batch interface feature. The batch Interface is started at CICS startup by the DADS PLUS PLTPI processing. Sometimes CA DADS Plus CICS batch requests are not running when CICS is active. The batch interface requests queue for the APPLID and the allocate or deallocate is not completed.
Some of the users submitting the batch interface requests do not have security access to the CA DADS Plus CICS batch interface transaction DADB. The batch job encounters a security violation and the DADB transaction abends due to this security violation. Once the DADB transaction abends the batch interface is no longer available on the CICS ICE chain and batch Interface jobs not be executed. They batch interface requests will QUEUE for the APPLID and not run.
Below is the error message you will see in the CICS Log.
