You can receive a SOC1 or SOC4 abend if you specify IBMTCP as the value of the Communications_Protocol configuration parameter and you do not have IBM TCP/IP running on MVS, or IBM TCP/IP terminates while Replication Agent is running.
To correct the abend condition when using TCP/IP
Determine which TCP/IP software is installed on MVS.
Edit the LTM for MVS configuration file to provide the correct value for the Communications_Protocol parameter.
Restart Replication Agent after ensuring TCP/IP is running.
See Appendix A, “LTM for MVS Configuration Parameters,” for more information on the Communications_Protocol parameter.
