Thanks very much for your various opinions; it's nice to have such a good sounding board. On 10/07/2011 11:20 AM, Shawn Drew wrote: I think he was looking for Power vs x86 in price/performance. I.E If you spend 50K on Power systems and 50K on x86 systems. which could produce more I/O throughput. (If not, that's what I'd like to hear an update on) Actually, I was aiming more for hardware/performance; this because price:hardware can be very customer dependant. I'm comparing, for example, systems with X cpus of Y gigahertz, with Z core and Q busses.. At a glance, it seems that the case is still strong for power, on similar hardware numbers. I'm trying to comb my bias out of the analysis, but I'm strongly in Richard's camp: On 10/07/2011 11:56 AM, Richard Sims wrote: The major challenge these days is not computer cost but the cost of supporting complexity, [...] My various generations of AIX on power substrate under TSM have been rock-solid for nearly 15 years now, and I've got 8+ TSM instances on each system image.

Does auditocc table show "reporting occupancy"?
When client backups are being deduplicated by the TSM server, does the audit occupancy table show "reporting occupancy" or physical space occupied by client data? Reporting occupancy is the space a client's data would occupy if it were not in a deduplicated pool. The Occupancy table shows "Reporting occupancy" in the Logical Occupancy field. What does the Audit Occupancy table show? Thank you, Keith
Re: Check signals on Power vs. x86...
I did have, but I needed space on the usb stick they gave out at the meeting and deleted them, and when I switched laptops recently several folders apparently didn't survive the trip. Since I didn't consider them important I never tried to recover them. Not sure if the numbers are still up on the web or not. You can always check www.spec.org (?) or tpc for published results.

Re: Defining Multiple filesystems to one FILEDEVCLASS in TSM v5.5
Well, now that we have multiple filesystems in this storage pool, we need to remove one without removing the already allocated volumes. The second filesystem we added to this FILEDEVCLASS just had a major error and has remounted itself as READ-ONLY (ext3 journling failed). So, how do I do this?

Re: Defining Multiple filesystems to one FILEDEVCLASS in TSM v5.5
you may add or remove directories to the deviceclass as you like, removing one will not cause the volumes already in there to be affected in any way.

Oracle TDP restore problem
We had some Oracle files deleted and we cannot restore the DB because we are missing the control file and catalog. We cannot figure out how to tell RMAN to restore the DB and logs without them. Is there a way? This is a TDPO backup without a working TSM agent backup. The node is running AIX. Andy Huebner This e-mail (including any attachments) is confidential and may be legally privileged.

Re: Oracle TDP restore problem
Usually recovery process quite complicated and depend on many things:
- a few copies of control files should be defined on different disks (see in
init file something similar to control_files=("/db/opcctl1","/db/opcctl2"). If
you still have at least one control file it is possible to copy it to lost
locations according to COLTROL_FILLES;
- if all copies of control files are lost, try to check if you have included
control files into backups (check RMAN scripts for "backup .database
include current controlfile;"). In this case it is possible to restore control
files from TSM by using restore controlfile to '';
replicate controlfile from '';
- a few copies of redo log files should be defined on different disks. If you
still have at least one redo log file in each group available, you are safe
(Oracle will take care about lost redo log files by using available files and
after restoring lost redo logs can be redefined). If you have lost all redo
logs at least in one group, you have to use incomplete recovery;
- database has to be in ARCHIVELOG mode and all archived redo logs are kept in
file system. If this file system is available, the latest archived redo logs
(not backed up to TSM yet) can be used from that file system during recovery;
- archived redo logs have to be included into backups (check used RMAN scripts
for command like "backup .(archivelog from logseq $START_SEQUENCE)".
If you have archived redo log backups, they will be requested during recovery
automatically;
SUMMARY:
1) If control files, redo log files, archived redo log file system and archived
redo log backups are available, just use (no data loss):
restore database;
recover database;
2) if only control files have been lost, first restore control file and use (no
data loss):
restore database;
recover database using backup control file;
3) if any redo log group has been lost use (data loss started from the last
applied archived redo log):
restore database;
recover database;
...
alter database open resetlogs;
General comments:
- you must be Oracle DBA;
- you mast be familiar with RMAN;
- you must be familiar with TDPO;
- etc.
Good luck!
