Our Oracle DBA's want to do multi stream restores using TDP for Oracle. I
have read in other posts using TDP for SQl all you have to do is set the
dest stgpool to Collocate by filespace. Ok, sounds easy but I don't think
that would work for the Oracle DB Backups. I say this as in the TDPO.opt

Was your 4-5 times faster going direct to a Physical Tape Drive? I ask as

any of the VTL Heads (Dilligent / Falcon Store etc) become the bottleneck.
I can see a stream to a 3592 or maybe an LTO3 drive do better than
Our Unix Admin has been able to script / automate the TDP for Oracle
Install but is wondering if anyone has been able to automate the
./tdpoconf password portion of the cfg. has anyone done this? If so were
you able to automate the TPO password set on the client side?

One of our TSM environments that is Backing up Unix and DB2 data is a bit
overrun at this point (lots of MediaW'). I was talking to our DB2 DBA and
he states that the final step to a On-line DB2 backup is to include the
transaction logs that occurred since the backup began. The DB2 log files
are
and should be shipped offsite. And the MediaW will disappear when the
DB2 log files go to disk.
best regards,
Kurt

Got a strange one. We have two libraries (VT1 and VT2 Virtual Tape
Emulating DLT7000) the Active Library VT1 Died, in haste we added in the
other Vtape Library VT2 and updated the devclass to point Library VT2.
Since then we've been able to get VT1 working again, but any time a Vtape
Req comes in
We had a situation where the same devclass was used for two different
Libraries. We then created two devclasses and associated one lib with the
original devclass and the other with a new devclass. The library with the
new devclass can not mount any volumes becuae the volumes are still
associated
I grew up with a 3494 (Some Consider Slow) but recently have been working
with a 3584. The 3584 is "dumb" in comparison, once a week we have to
idle down TSM and re-inventory the 3584 because it always looses its
inventory and cant mount tapes or puts them in the wrong slots! Sooo

Yep... Also the maxScr does play a role, you may have a diff in max scr

This is why we still front end with Diskpools... as we have had CDL and
VTFopen VTL's go to lunch. Our philosophy is we need to get a good backup
and do not want to have our DBA's move Logs around while we fix the VTL...

Being that TSM does incremental, your de-dupe ratio will be lower than
other Full / Incr backup products. Here's a few lessons learned with TSM
and a Diligent Protectier.
1) Do the best you can to put like data together. (ie all Oracle
DB Backups go to the same de-dupe VirtualTape head (R
According to Dilligent, when RMAN uses Multiplexing, it intermingles the
data from each RMAN so the data block will be different every time so the
blocks are different, similar to Multiplexing with Netbackup... I'm not
an RMAN expert, just trusting what the Vendor is stating.

You're correct, in that there are products that can provide a more global
