I ran
run
{
allocate channel c1 device type sbt format 'df_%t_%s_%p' maxpiecesize=2048M
PARMS="SBT_LIBRARY=/opt/oracle/dbserver/9.0.1/lib/libobk.so,
ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin/tdpo.opt)";
restore archivelog sequence 9645 validate;
release channel c1;
}
And was successful, I ran it without the validate, and it restored the log file. The "restore database validate" was also successful. So it appears everything is fine. Except for the information in the rc_archived_log object and what is returned from the "list archivelog all command".

A few days ago the physicists turned on what they call the waveform channels. The channel archive database tracking this information was able to withstand the additional 2,000,000 rows per hour load for 20 + hours. Then the 257 errors hit. As we are migrating from a very old ADSM system to TSM with a better SILO, this database seemed a good choice. The old backup system is still handling a score of databases without using RMAN. I was also able to procure an additional 18 GB internal disk on which to place the archived redo logs. I shutdown the channel archive database (9.0.1.3) changed the destination parameter for archive logs to point to the new location, then did an alter system switch logfile. I then logged into the RMAN catalog and registered the database for the first time.
I tried
run
{
allocate channel c1 device type sbt format 'df_%t_%s_%p' maxpiecesize=2048M
PARMS="SBT_LIBRARY=/opt/oracle/dbserver/9.0.1/lib/libobk.so,
ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin/tdpo.opt)";
backup archivelog all delete input;
release channel c1;
}
But it wanted log sequence 8192 which was backed up and deleted on the old system long ago.
Any way
run
{
allocate channel c1 device type sbt format 'df_%t_%s_%p' maxpiecesize=2048M
PARMS="SBT_LIBRARY=/opt/oracle/dbserver/9.0.1/lib/libobk.so,
ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin/tdpo.opt)";
backup archivelog from sequence 9645 delete input;
release channel c1;
}
Backed up that log file. I then ran a backup of all the data files to get even the read only ones, and then a backup of the read write tablespaces. I didn't include archive logs in these backups. I have asked the physicists to hold off on their 2,000,000 rows per hour data which they can do for a while. They had some other waveform data which created slightly over 7,000,000 records per day. I placed the archive log backup as written above into a different cron job. Currently invoked hourly, than the one for the database backup invoked daily.
All backups use the recovery catalog. The catalog database is 9.2.0.3. Here's the gist of the problem select name from rc_archived_log where db_key = 6411;
(Many previous rows removed)
NAME
List archived logs from the old location. These were never backed up by RMAN.
List archivelog all;
Again lists only old archive files never backed up by rman

That doesn't look good. I've just started a "restore database validate." It may be
my ignorance but not everything seems to jibe. I must have left out a step.
