IBM AnyNet QAPPCTCP Job (AnyNet) Fails to Start with Message TCP4F99

Troubleshooting


Problem

IBM AnyNet will not start after IPL or after STRTCP or after running the CHGNETA command from ALWANYNET(*NO) to (*YES). Message TCP4F99 is posted in QAPPCTCP joblog.

Resolving The Problem


========================================================================================
Important Note: Starting in i 7.1, AnyNet (a method used to run SNA communications traffic
over IP) is no longer supported. Users of AnyNet are encouraged to migrate to Enterprise
Extender as a replacement.
=============================================================================


IBM AnyNet will not start. The QAPPCTCP job in OUTQ status has the following message in the
QPJOBLOG.

TCP4F99 Escape 50  11/08/02  9:00:11   QZPAIJOB  QSYS   0398      
Message . . . . :   Internal system error in program QZPAIJOB.
Cause . . . . . :   An internal system error has occurred in program QZPAIJOB.  This is an APAR condition.
Recovery  . . . :   This is not a normal condition. Check the job log for
other messages sent prior to this one. They may help determine the source of
the error. Report the problem using the ANZPRB command.
Technical description . . . :   This message is sent when an internal error

Problem Resolution

Ensure there is only one QZPAIDOMAN data area on the system and that the length
is 32 characters.

                              Display Data Area                                
System:   RCHAS194
Data area . . . . . . . :   QZPAIDOMAN
Library . . . . . . . :     QUSRSYS  
Type  . . . . . . . . . :   *CHAR
Length  . . . . . . . . :   32
Text  . . . . . . . . . :

    0      'SNA.IBM.COM   '
                         

This data area is used by AnyNet to store the host name used to resolve an IP address. By default it is
SNA.IBM.COM. It can be changed to any other valid host name that is not longer than 32 characters. Use
the CHGDTAARA command to configure the data area properly for your system. In addition, if there are
any other QZPAIxxxxx data areas on the system, they should be deleted. Only one is required in library
QUSRSYS as described above.

Additional Information

Other errors can include TCP4F02 or MCH1202 when AnyNet is trying to start.

To determine if the situation can be resolved do the following:

1To find all data areas used by AnyNet, run the following command from the operating system command line:

WRKOBJ OBJ(QZPAI*) OBJTYPE(*DTAARA)
2Data areas used by AnyNet include:

QZPAIKPANR
QZPAIKPART
QZPAIKPATM
QZPAIDOMAN
QZPAIPORTN

If any of these exist, rename them and restart AnyNet. If AnyNet starts, these data areas are more than likely corrupted and must be rebuilt.
