Re: [ADSM-L] Sessions idle for silly periods...

Hi Allen,

yes, I am seeing sessions hang like this.  The sending server is version
6.
The receiver is 5.5.  I am making the copypools for the v6 servers on
virtual
volumes.  I get hanging sessions like this when doing backup stgpool and
also doing
tsm db backups to the same 5.5 server.  I monitor it every morning and
cancel the
hanging sessions. I have a pmr open.

If you look in the sending server, you should see messages like this -

tsm: XXXX>q act begint=00:00 s=socket
Session established with server XXXX: Linux/x86_64

Have any of you seen server-to-server sessions stay around, idle, for
ridiculous periods?

I have a server with


tsm: ATLCOPY>q opt idletimeout

Server Option         Option Setting
-----------------     --------------------
IdleTimeOut           60


but it accumulates idle sessions:

Makes me wish for

CANCEL SESS wherestate=IdleW Wherewait >= 6000

or some such.
