APPC or CPI-C TPs May Fail When Using Dependent LU 6.2 SessionsLast reviewed: February 4, 1998Article ID: Q180416 |
The information in this article applies to:
SYMPTOMSAn APPC or CPI-C application may fail to get an active conversation with a host if a previous conversation over the same Local APPC LU has ended. For example, if there was a conversation over local LU LOCAL1 and remote LU REMOTE1, an APPC or CPI-C application may fail to get an active conversation over local LU LOCAL1 and remote LU REMOTE2 even if the previous conversation has ended. When this occurs, the APPC or CPI-C application call to [MC_]ALLOCATE or CMALLC never completes because SNA Server has not unbound the previous dependent LU/LU session before attempting to solicit a bind to a different Remote APPC LU. NOTE: This does not occur when you use Independent LU 6.2 sessions.
CAUSESNA Server is not ending the previous dependent APPC session by sending an UNBIND to the host. This causes any additional APPC sessions over the same local APPC LU and different remote APPC LUs to fail to get active conversations until the first APPC session is shut down.
STATUSMicrosoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0 SP1, 3.0 SP2, and 4.0. A fix to this problem is available, but has not been regressiontested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for more information on the availability of this fix.
MORE INFORMATIONThe SNA Server service has been updated so that it will unbind the initial dependent APPC session if it is not active when it receives a request to open a new APPC session over the same local APPC LU and a different remote APPC LU.
