202: NO_PIPE

An attempt has been made to open a pipe, but the target CICS® system associated with the pipe has no free receive sessions.

Explanation

System Action

The Open_pipe call fails, and the external CICS interface invokes the user-replaceable module, DFHXCURM.

User Response

This situation can occur even if the client application program has allocated (using Allocate_Pipe calls) no more pipes than the number of receive sessions defined on the target connection. This is because CICS can be in the process of cleaning up a pipe from a Close_Pipe request. For this reason, you are recommended to specify a larger RECEIVECOUNT value than is theoretically necessary when defining the SESSIONS resource definition to CICS. The application program can reissue the Open_Pipe request.
