Re: [ADSM-L] TSM: Backing Up Large Files

Changingretries 50 WOW!
OK, that is just the number of times to retry an open/active/changing
file... your issues are connection issues... that parm won't help you and
honestly, I'd back that way back down to something like 4 or less. Picture
sending a 4 GB file 50 times trying to capture a static copy of it... that's
200 GB's of data moved for just a single 4 GB file. (potentially) and you
still might just end up throwing it away depending on your serialization
settings.
I don't believe 5.4 code is supported anymore but you might try upgrading
your client to something a little newer like the most recent 5.5 client.
Also check your tsm server's activity log for anything that might explain
why the session is being lost.
My guess is that if you were watching the session, you will see it just go
into an idle wait state until it times out. (with no clear reason for it
going idle)
You might try adjusting the following parameters on your client:
TCPWindowsize
TCPBUFF
TXNBYTELIMIT
You can tune those so that the client will function better based on the
dependability of your network.
To me what you are seeing is there is something getting lost in the network
transmissions.

Subject: [ADSM-L] TSM: Backing Up Large Files
Hello:
I need some on advice on how to handle backing up large files, more
specifically, a 4 GB file. I am running a small TSM instance running
version 5.4.2.0 and the client is also running 5.4.2.0. This is what the
client log says when trying to backup file:
07/23/2012 09:51:42 Retry # 1 Normal File--> 4,457,963,520
\\ami-hph-pacs\d$\Program Files\RamSoft\DB4\PACS46REST.FDB ** Unsuccessful
**
07/23/2012 09:51:42 ANS1809W A session with the TSM server has been
disconnected. An attempt will be made to reestablish the connection.
07/23/2012 09:51:57 ... successful
07/23/2012 10:24:00 Retry # 2 Normal File--> 4,457,963,520
\\ami-hph-pacs\d$\Program Files\RamSoft\DB4\PACS46REST.FDB ** Unsuccessful
**
07/23/2012 10:24:00 ANS1809W A session with the TSM server has been
disconnected. An attempt will be made to reestablish the connection.
07/23/2012 10:24:15 ... successful
It retries about five times and then fails. Here is the output of "q
option" from my TSM instance:

I made a few changes that I thought would help, but hasn't so far. I
changed the "Retry Period" from a specified time to "Client". I also added
a client option to the client option set called "CHANGINGRETRIES" and set
the value to "50". Is there a way to change the minutes between retries?
Can someone please point me the right direction?
Any suggestions would be greatly appreciated!
Thank you...
Charles
