What does CCITCP do? Is it a communication link between CA products and TCPIP?
A client-server configuration supports PC-to-mainframe connections. It uses one of the following CAICCI TCP/IP server started tasks.
CCITCP, which is started using the CAICCI PROTOCOL(TCPIP,…) control option
CCISSL with SSL support, which is started using the CAICCI PROTOCOL(TCPSSL, …) control option.
The user ID of the used started task must have a valid OMVS segment. Consult you security product for the minimum requirements to setting up an OMVS segment. Sample members of the CCI started tasks are distributed in the CAW0PROC data set.
There are a number of CA Products that can utilize CCITCP/CCISSL. One example is CA Datacom Server which is installed on a windows platform along with CAICCI/PC. A CA Datacom Server request is initiated and passed to CCI/PC which "talks" to CCITCP/CCISSL on the mainframe, which would query CA-Datacom on the mainframe. The request is fulfilled and passed back to the CA-Datacom Server application.
