7111.0. "-SNA-E-SESNOTAVA on an ACTIVATED LU???" by KERNEL::WEGG (Ian Wegg - UK TSC) Thu May 29 1997 12:21

I have reached a deadlock with a customer, and the only way forward is for me
to ask the question here (no matter how stupid it appears to be).

The customer's application, layered on DECMessageQ LU6.2, received the error:

%SNATERM-E-FAIESTSES, failed to establish session
-SNA-E-SESNOTAVA, session address has not been activated

However they insist that, at the time, the LU *WAS* activated.  The Gateway
is a Peerserver V1.3, and the applcation is on VMS using LU6.2 2.2-14.

My question, is it possible that this configuration could ever return a 
SESNOTAVA status for any other reason than the documented "session address has
not been activated"?  The problem was confined to a single LU.

    Ian,
    
    Peer Server has both dependent and independent halves of the LU.
    The dependent half has to be active.    Below are two LU's in our
    Peer Server status. Notice the second one will not allow DMQ access
    for the reason of SESNOTAVA.

    	Bill,
    
    	Thanks for the information. When I spoke to the customer the LU 
    	was as you describe in the second case (i.e.  Dependent LU Protocol 
    	State  = Inactive ) and therefore expected. They insist
    	that it WASN'T like this when they had the problem, but I'm not
    	convinced they really knew this.
    
    	I'll get them to reactive the LU and try it again with tracing.
    	If I can get any evidence of SESNOTAVA with the Dependent LU
    	protocol State of Active I'll be in touch, but please don't lose 
    	any sleep. :-)
    	
        As a side issue, what is engineering's position with VMS 6.1
    	and LU6.2 V2.2?  Would an escalation still be accepted on these
    	versions or would you insist on the customer upgrading? 
    
    	~Ian.

    You can escallate with those versions, but analysis may prove
    a fix already exists, or change in functionality changed the 
    behavior with the V2.3 release.
    
    I would suggest you upgrade to V2.3 ECO-01.
