Are you backing up directly to a tape or a disk storage pool?
If you are going to a tape pool do not start more sessions than you have
physical tape heads.
Check the TSM Server's activity log to see why the -50 was returned to the
client, I suspect that the idletimeout parm came into affect and terminated
the session. I would recommend that you increase the COMMTIMEOUT and
IDLETIMEOUT values to something like 6000

[DB2EUG] Error on backup to TSM

Hello;
I have a database that's around 50 Gig. I use this command to run my
backup.
db2 -v backup database proddb online use adsm without prompting
.
It takes 5 hours to complete.... I spoke to TSM people and asked if there's
a way they can help us to complete this backup at less then 5 hours.
Normally it used to take 2 hours. They are looking into it.
So, in my end, I try to change the backup commands to see if I can improve
the backup process... I did something like this:
backup database proddb online use adsm open 2 sessions with 4
buffers without prompting.
After a while I'm getting this error:
SQL2025N An I/O error "-50" occurred on media "TSM".
"-50" accourding to API Return code it means:
-050 E DSM_RC_TCPIP_FAILURE
Explanation: An attempt to connect to the server using TCP/IP
communications
failed. This error can occur if the LAN connection went down or
if your system administrator canceled a backup operation.
System Action: Session rejected. Processing stopped.
User Response: Retry the operation, or wait until the server comes back up
and
retry the operation. If the problem continues, see your system
administrator for further help.
But If i don't say "open 2 sessions with 4 buffers" it will run but
takes 5 hours.
Any help.
Thank you.
