Error description
You get a loop when trying to invoke a request stream transaction. You are using a Distributed Routing Program that was not setup via the DSRTPGM SIT parm. Instead, you use CPSM or EXEC CICS SET SYSTEM DSRTPROGRAM to name the Distributed Routing Program later after startup. Then when the request stream arrives, the Distributed Routing Program requests that the transaction run locally. In that situation, the loop occurs.
Local fix
Use SIT parm DSRTPGM to establish the Distributed Routing Program.
Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: A loop occurs when trying to invoke a * * webservice locally after setting up a * * distributed routing program after CICS * * startup. * * * **************************************************************** * RECOMMENDATION: * **************************************************************** CICS is being used as a Web Service Provider. A context switch occurs as part of the pipeline processing. If the context switch specifies a new transaction and the new transaction is defined as Dynamic=Yes request streams has to call the Distributed Routing Program to determine which region the new task is going to be run in. An earlier EXEC CICS SET SYSTEM DSRTPROGRAM had been issued to set the name of the Distributed Routing Program. As part of that DFHRZRT FUNCTION(SET_EXIT_PROGRAM) was called to set the request streams copy of the routing program name. This routine also incorrectly cleared out the request streams copy of the local sysid. When the routing program is called it returns the local sysid. DFHRZRT compares the sysid with the request streams copy of the local sysid and finds that they don't match, it then attempts to run the task remotely. This fails because the sysid is not a remote system. The routing program is called again for the route selection error. If it returns the local sysid again, then a loop of routing failure and calling the routing program occurs.
Problem conclusion
Module DFHRZRT has been changed to update the local sysid when a new (e.g. non-null) value has been passed in so that EXEC CICS SET SYSTEM DSRTPROGRAM only updates the program name.
