Robert, i needed to restore some archivelogs(for applying to a clone,
its a long story, firewall issues, etc), anyways, i restored them,
pushed them to new server, deleted from disk(original source
archive_dest), this messed up repository, i couldnt ever get the
crosscheck to mark things as expired, i eventually had to uncatalog
those archivelogs and then all was fine, really weird.

Ian,
This is a problem I run into a great deal. Before you backup issue this
command (I assume 9i here and pre-configured defaults so no allocate channel
commands):
crosscheck archivelog all;
backup database archivelog all;
The crosscheck command will compare the archivelogs currently on disk to
those in the control file. Any missing will be marked expired. If you were
to restore them you can run the crosscheck command to remark them as
available.

Ian,
You can try resyncing the catalog and if that still doesn't work try to
uncatalog that log:
rman> change archivelog '/full_path/log_name_8192.arc' uncatalog;'

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)

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.
