SYMPTOMS
The SNA LU6.2 Resync TP service may incorrectly log event 134 errors in the application event log. The service may log these events while the service checks for orphaned Remote APPC LUs in the Microsoft Host Integration Server 2000 configuration.

For a definition of an orphaned Remote APPC LU, see the &quot;More Information&quot; section.



CAUSE
This problem occurs when there are multiple Local LUs in the subdomain that are configured for different Resync clients. This behavior causes the SNA LU6.2 Resync TP service to use an incomplete list of SyncPoint enabled Local APPC LUs. This behavior causes incorrect logging of event 134 errors for Remote APPC LUs that are not orphaned in the Host Integration Server 2000 configuration.



Service pack information

MORE INFORMATION
The SNA LU6.2 Resync TP service retrieves a list of all the Local APPC LUs and all the Remote APPC LUs that are configured to support SyncPoint services. The SNA LU6.2 Resync TP service also checks the Host Integration Server 2000 configuration to determine whether any one or more of the SyncPoint enabled Remote APPC LUs are orphaned.

Orphaned Remote APPC LU - An orphaned Remote APPC LU is a Remote APPC LU that has been SyncPoint enabled and that has been created on an SNA Server service (Snaservr.exe) that does not have any Local APPC LUs that are SyncPoint enabled. The SyncPoint enabled Remote APPC LU is orphaned because no SyncPoint enabled Local APPC LU to be partnered with exists on the same SNA Server service.

The SNA LU6.2 Resync TP logs the following event 134 error if an orphaned Remote APPC LU is detected:

Event ID: 134

Source: SNA LU6.2 Resync TP

Description: (134) The Resynchronization Service encountered a Remote LU with no SyncPoint-capable partners.

Explanation: The Resynchronization Service found Remote LU  on SNA Service. The SyncPoint property was enabled, but no Local LUs with the SyncPoint property and LU 6.2 Resync Service Computer field equal to  were found on the SNA Server service.

Example scenario
The following is an example configuration that results in the SNA LU6.2 Resync TP service logging an incorrect event 134 error.

In this configuration, all the APPC LUs are configured to support SyncPoint services:
 * Local APPC LU LOCAL1 is configured to work with the SNA LU6.2 Resync TP service running on CLIENT1.
 * Local APPC LU LOCAL2 is configured to work with the SNA LU6.2 Resync TP service running on CLIENT2.

The following sequence of events occurs in this example scenario:
 * 1) When the SNA LU6.2 Resync TP on CLIENT1 starts, it retrieves a list of the APPC LUs and determines the APPC LUs that are enabled to support SyncPoint services.
 * 2) The SNA LU6.2 Resync TP service on CLIENT1 keeps an internal list of all the Local APPC LUs that support SyncPoint services and that are configured with a computer name of CLIENT1.
 * 3) The SNA LU6.2 Resync TP service on CLIENT1 determines that REMOTE1 and REMOTE2 are enabled to support SyncPoint services.
 * 4) The service checks to determine whether either REMOTE1 or REMOTE2 are orphaned.
 * 5) Because the Local APPC LU list that the SNA LU6.2 Resync TP service has contains only LOCAL1, the service incorrectly determines that REMOTE2 is an orphaned Remote APPC LU because the Local APPC LU list does not contain LOCAL2.
