GET_TP_PROPERTIES Fails with INVALID_VERB Response Code (313684)


The information in this article applies to:

  • Microsoft Host Integration Server 2000
This article was previously published under Q313684

SYMPTOMS

When an invokable Advanced Program-to-Program Communications (APPC) transaction program calls GET_TP_PROPERTIES, the program may receive an INVALID_VERB (0xFFFF) response code.

CAUSE

When an invokable APPC transaction program issues a RECEIVE_ALLOCATE command, the program waits for a partner APPC transaction program to start an APPC conversation. The partner application triggers an FMH-5 Attach message to start the APPC conversation with the invokable APPC transaction program. This FMH-5 Attach command may contain a logical unit of work identifier (LUWID) for the APPC conversation. In some cases, Host Integration Server 2000 (HIS 2000) does not properly recognize this LUWID. An LUWID must be established before the APPC program calls GET_TP_PROPERTIES. If HIS 2000 does not recognize the LUWID that the partner system sent, the call returns the INVALID_VERB response code.

A concurrent SNA application internal trace shows the following: 
17:14:40.0875 appc_c.c(2596)     INVBC ERROR: Cannot GET_TP_PROPERTIES 
before obtaining LUWID
The FMH-5 Attach command is captured in the SNA Server Data Link Control message trace. If you examine the FMH-5 Attach command that was sent from the host, you will see that a valid LUWID was sent.

For more information on the structure of an FMH-5 Attach command, see the IBM SNA Formats guide (IBM document GA27-3136-12).
