Hi All I have a situation that is causing me grief. As part of a V5 to V6 upgrade I have implemented library managers. These live in one part of the network and the library clients live in another separated by a firewall. The customer insists that timeouts be implemented on the firewall for any session over 60 minutes: its a security thing for some reason and is non-negotiable.
At times I get a lot of mounts queued, in the past when these were local mounts, they would eventually resolve themselves but now they time out in the firewall, never complete, and I get a cascading blockage until the whole server grinds to a halt. I'm told I can set recourcetimeout to less than the firewall timeout and that will cause the mounts to fail, but a lot of these are oracle and DB2 backups and they won't retry in a reasonable manner. Yes, I could use devicelasses and mount limits to reserve drives, and I could put some stuff on disk that now goes direct to tape, but neither of those are palatable. Of course the easiest thing would be to have the library clients use keepalives on their sessions, as was added in recent versions for NDMP backups. I have raised an RFE to this effect at http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=54030 and I'd appreciate your votes. Does anyone have bright ideas on how to proceed? I have thought about SSL port forwarding, but apparently bypassing the controls that way is frowned upon. Even if the RFE gets up, it won't help me as half of the clients are still TSM 5.5 for the next six months or so while we cut them over. Thanks Steve Steven Harris TSM Admin Canberra Australia.
