QCSTCTRMCD Port Conflict with BPICS Application

Troubleshooting


Problem

Applications that need port 5000 or 5001 should use a port restriction for the desired port(s).

Resolving The Problem

Problem Description

A BPICS application fails to start because ports 5000 or 5001 are in use. NETSTAT shows port 5001 being used by job QCSTCTRMCD. This job is commonly associated with RMC.

Problem Resolution

QCSTCTRMCD requests the next available user port during its startup. The start of the ephemeral port range for IBM i5/OS is 5000. Depending on the system configuration, the jobs started at system startup, and the timing of the startup, a job such as QCSTCTRMCD might be assigned port 5001. To prevent the problem from occurring again, enter a port restriction for the application. To free up the port immediately, end and restart the QCSTCTRMCD jobs.

1.Enter the port restriction. Type the following command:

CFGTCP

Select Option 4. Work with TCP/IP port restrictions.

Add a port restriction for the desired ports and user profile. The user profile is the user profile of the job that will use this
port or range of ports:

        --Port Range---                  User        
Opt     Lower     Upper     Protocol     Profile      
1       5000      5001       *TCP       <profile>

Note: If BPICS is installed, the user profile will show up as BPICS user profile.
2.End the RMC daemon jobs (including QCSTCTRMCD). Type the following command:

V5Rx
ENDJOB JOB(QCSTSRCD) OPTION(*IMMED) DUPJOBOPT(*SELECT)
Press the Enter key. If the Select Job screen is displayed, type 1 on the active job, and press the Enter key.

V6R1 and later
ENDJOB JOB(QRMCSRCD) OPTION(*IMMED) DUPJOBOPT(*SELECT)

Press the Enter key. If the Select Job screen is displayed, type 1 on the active job, and press the Enter key.
3.Restart the RMC daemon. Type the following command:

V5Rx
SBMJOB CMD(CALL PGM(QSYS/QCSTCTSRCD)) JOBD(QSYS/QCSTSRCD) PRTDEV(*JOBD) OUTQ(*JOBD) USER(*JOBD) PRTTXT(*JOBD) RTGDTA(RUNPTY50)

V6R1 and later
SBMJOB CMD(CALL PGM(QSYS/QRMCCTSRCD)) JOBD(QSYS/QRMCSRCD) PRTDEV(*JOBD) OUTQ(*JOBD) USER(*JOBD) PRTTXT(*JOBD) RTGDTA(RUNPTY50)
