Hello:
Thank you to all that replied. The problem appears to have been fixed. I made
the following changes to my TSM client, but not sure which one actually did the
trick:
# 1: Increased the values of "TCPBUFFSIZE" and "TCPWINDOWSIZE" from 64 to 128.
# 2: Increased the value of "TXNBYTELIMIT" from 25600 to 2097152.
# 3: Upgraded the TSM client software from 5.4.2.0 to 5.5.2.0.
# 4: Set RESOURCEUTILIZATION to 1 (refer to
http://www-01.ibm.com/support/docview.wss?uid=swg21402687). According to the
document, setting RESOURCEUTILIZATION to 1 will eliminate the sessions being
terminated due to time out. Tivoli Storage Manager will share one session for
both producer and consumer sessions.
# 5: Removed the "CHANGINGRETRIES" option from the client option set. I
originally added it for troubleshooting purposes, although I found out later it
wasn't something I should do.
I just wanted to thank you for your responses as well as let you know that it
is working and what I did to resolve.

Charles,
I support Wanda's suggestions, and would like to add another possibility.
For some time we were experiencing nightly issues where the backup of large
files was causing log-pinning and ultimately the backup processes were being
canceled, as well as larger backups taking a long time to complete.
The cause ended up being poor performance of my disk pools, which could happen
with tape as well. Bypassing this storage temporarily and sending data straight
to the next storage pool corrected the problem and we ultimately replaced them
with higher performing ones.
I suggest if your WAN/LAN connections turn up nothing don't forget to take a
look at the disk/tape storage performance. Don't forget the SCSI, fiber, and/or
network connections of your storage devices.
The TSM server itself should have no issues with a 4 gig file.
Good Luck!
~Rick

I don't think you told us whether this is a WAN connection or GIGE?
4G is quite a relatively small file for TSM to handle, so looks like connection
issues.
1) Check to see if there is a firewall between your server and the client. If
so you will need to have the firewall guy increase the firewall (not TSM)
timeout allowed between the TSM server and this client on port 1500, at least
for debugging purposes (assuming you are using the default port 1500).
2) Best test for diagnosing connection problems is always to first take TSM out
of the picture.
If you can open up an FTP server on the TSM Windows server, use FTP to move
that 4 G file (actually I'd feel better if you were testing with a 10G file)
between the client and server, see what throughput you get.
Run the get/put 5 times in each direction. Each time throw away the first set
of numbers, average the last 4.
If you aren't getting GIGE throughput on a GIGE line, that's not a TSM issue,
it's a TSP/IP-connection issue.
If you can't use FTP, use Windows drag and drop to move that file between the
client and server, multiple times, both directions. See what throughput you
get.

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...
