T-Server log question

[Glenn]

Hi all,

I'm looking into T-Server log files (Avaya CM) to check for performance etc.  I found the following, but I don't know what it means.  Can somebody help me:

The environment has two T-Servers in hot standby.  While digging in the log files, i find messages are sent over 5 different links:

Backup link[1] : incoming messages on the backup link
Backup ts7.2.012.01[1] : outgoing messages on the backup link
Primary link[1] : incoming messages on the primary link
Primary ts7.2.012.01[1] : outgoing messages on the primary link

These are obvious, but now my question:
Primary link-duplicate[1] : I have no idea what this link is.  I was thinking that this link is for the hot-standby, but I'm not sure.  Can anybody help me?

Check first how many links you have per TServer, you should have two, do you?

I'm not sure if this is what you mean, but in my T-Server configuration I only have a [link-1-name], not a [link-2-name]

Sorry, I misread what you wrote: as you said, you probably have 2 TServer, one link each. And you don't have 5 links, you just have 1 link primary and 1 link backup. Backup link[1] and Backup ts7.2.012.01[1] are the same link, simply when that link receive a message from the switch it logs "Backup link[1]", when instead sends to the switch on that same link, it does "Backup ts7.2.012.01[1]".
The duplicate stuff..I can't remember, but anyway nothing to be worried about.

Well, the reason why I wanted to know is because a lot of traffic is generated through this link.  I was just looking for some information what this link is and what it does.  Thanks for your help...

Glenn,

I'd also like to have a stab at this, if I may...?


I think the confusion is in having an HA TServer (that is; 2 x TS, one primary and one backup) - and you may also have a primary and backup of your PBX/Switch Link (2 x Links).

It is possible that your Primary TServer is set against [i]Link1[/i] and your Backup TServer is set against another name - what you really should check is the IP Address of both links.  If the IP Address and Port of [i]link1[/i] and [i]link2[/i] are both the same, then it doesn't matter what the "name" of the Link is - they are the same connection.

What I think you have is;

TServer1 (Primary) - connected to [i]link1[/i] (IP Address1)
TServer2 (Backup) - connect to [i]link2[/i] (IP Address1)

- If you want to "do things properly" you might want to check if you do have 2 live IP Addresses/Ports for your PBX/Switch.  If you do, then you might want to set your TServers as follows;

TServer1 (Primary) - connected to [i]link1[/i] (IP Address1)
TServer2 (Backup) - connect to [i]link2[/i] (IP Address2)

Otherwise, if the PBX/Switch only has one link (that is - one live IP Address/Port), it is perfectly OK to set up your HA as follows;

TServer1 (Primary) - connected to [i]link1[/i] (IP Address1)
TServer2 (Backup) - connect to [i]link1[/i] (IP Address1)

I do hope I have understood your issues  and this helps, in some way..?
