SYMPTOMS
When automatically activating a dependent LU6.2 session, SNA Server sends an INIT-SELF command to the host, to request that the host send a BIND command to start the LU6.2 session. If the host sends a negative response to the INIT-SELF request, SNA Server does not resend the INIT-SELF command unless an APPC or CPIC application attempts to allocate a new conversation on this dependent LU6.2 session (using [MC_]ALLOCATE or CMINIT). Automatic activation for a dependent LU6.2 session is configured on the APPC mode definition by setting the Automatic Activation Limit to "1."

Retry logic for INIT-SELF has been added to SNA Server. This allows SNA Server to retry an INIT-SELF for a dependent LU 6.2 after it has been rejected by the host.

NOTE: SNA Server 3.0 does not support the automatic activation of LU6.2 sessions, so session activation only occurs after an SNA Server APPC or CPIC application attempts to allocate a conversation over the dependent LU 6.2 LU's, or if initiated by the host.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
The following two new registry parameters are now supported:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SnaServer\Parameters

INITSLFRETRIES: REG_SZ: (default 0) This parameter specifies the number of times an INITSELF is retried.

INITSLFTICKS: REG_SZ: (default 2) This parameter specifies the number of tick periods (about 5 seconds) between each retry.

The SNA Server Service must be restarted after making these changes.

Even though this functionality was not included with SNA Server 2.11, a fix that provides this functionality is available for SNA Server 2.11 Service Pack 1.

Additional query words: dependent lu 6.2 bind prodsna
