Starting of TCP/IP Interface Fails with Message TCP1B01

When using the STRTCPIFC command, or when trying to start a TCP/IP interface from the NETSTAT or CFGTCP menus, the start attempt times out with error message TCP1B01. The message reads:

Message ID . . . . . . . . . : TCP1B01

Message file . . . . . . . . : QTCPMSG

Library . . . . . . . . . : QSYS

Message . . . . : Unable to determine if &1 interface started.

Cause . . . . . : The QTCPIP job in the QSYSWRK subsystem is not active, or the default wait time for your job was exceeded while waiting for the interface to start.

Recovery . . . : Use the Work with Active Jobs (WRKACTJOB) CL command to list the active jobs in the QSYSWRK subsystem. If the QTCPIP job is not active, issue the End TCP/IP (ENDTCP) CL command followed by the Start TCP/IP (STRTCP) CL command. After STRTCP completes processing, issue the Start TCP/IP Interface (STRTCPIFC) CL command again. If the QTCPIP job in the QSYSWRK subsystem is active, continue to look in the QTCPIP job log to determine if the &1 interface was started. To avoid this problem when using STRTCPIFC, wait for system activity to decrease, or increase the default wait time for your job using the Change Job (CHGJOB) CL command.

Despite the recovery action listed, the problem can actually be due to authority issues. When using the WRKJOB command on the QTCPIP job (WRKJOB QTCPIP), it is possible to see no active QTCPIP jobs. Working with the most recent job in OUTQ status, and reviewing the joblog, it is very likely that message CPFA09C is posted in the joblog. Typically this message refers to an object named QLGPGCMA.LOCALE. However, the message can vary. It is very possible that the object is an Integrated File System object and is potentially the root directory ('/'). Verify the root directory's authority by using the command WRKLNK OBJ('/') or verify the authority to the object identified in the error message. Use Option 9 to view the authority, and ensure *PUBLIC is not set to *EXCLUDE.
