SYMPTOMS

SNA Server and Host Integration Server 2000 both support the ability to run LU6.2 applications locally against a single server over two local APPC LUs. This configuration allows an APPC or CPIC application developer to test two Win32 LU6.2 applications on a single server without the need for an SNA connection. However, when you run a pair of APPC or CPIC applications in this configuration, SNA Manager or the Microsoft Management Console (MMC) snap-in display one of the local APPC LUs as [Not In Use] when the LU is actually in conversation with another local APPC LU.

For example, when you run APING and APINGD sample applications on the same server by using local APPC LU LUPING and LUPINGD, the LUPING correctly displays the User Name of the APING application when it has an active LU6.2 conversation; however, when LUPINGD displays a session to LUPING, the User Name appears as [Not In Use].

NOTE: This problem does not occur when you use local APPC LUs against remote APPC LUs. However, if the LU6.2 conversation is very short, SNA Manager or the MMC snap-in displays the LU6.2 session status as [Not In Use]. The LU6.2 conversation must exist for several seconds in order for the conversation status to be refreshed.

CAUSE

The problem displaying the local APPC LU conversation status for a single, locally partnered session is a known problem in SNA Manager and the MMC snap-in.

WORKAROUND

Find the local APPC LU that is displaying the LU6.2 conversation usage, and view its status to monitor session state.

STATUS

Microsoft has confirmed that this is a problem in SNA Server 3.0 (all SPs), 4.0 (all SPs) and Host Integration Server 2000.
