List,

When I got into work this morning I noticed u01 was nearly full on out production OLTP machine. I found the files and the looked to be RMAN files. They were all in '$ORACLE_HOME/dbs/.' My first thought was that they were the snapshot controlfiles. ....but aren't those automatically deleted? I double checked the RMAN scripts I use to make sure nothing was explicitly written there. They weren't. So I deleted those files. I next ran the following on one of the databases:

RMAN> run {

2> allocate channel d1 type disk;
3> restore database validate;
4> }

that returned successfully. (whew)

then:

RMAN> run {

2> allocate channel d1 type disk;
3> restore controlfile validate;
4> }

RMAN-03022: compiling command: allocate
RMAN-03023: executing command: allocate

RMAN-08030: allocated channel: d1
RMAN-08500: channel d1: sid=14 devtype=DISK

RMAN-03022: compiling command: restore
RMAN-03025: performing implicit partial resync of recovery catalog
RMAN-03023: executing command: partial resync
RMAN-08003: starting partial resync of recovery catalog
RMAN-08005: partial resync complete

RMAN-03022: compiling command: IRESTORE

RMAN-03023: executing command: IRESTORE
RMAN-08518: channel d1: scanning controlfile copy /oracle_backup/ASTU/astu_ctl

RMAN-03026: error recovery releasing channel resources
RMAN-08031: released channel: d1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure during compilation of command
RMAN-03013: command type: restore
RMAN-03006: non-retryable error occurred during execution of command:

IRESTORE
RMAN-07004: unhandled exception during command execution on channel d1 RMAN-10035: exception raised in RPC: ORA-00600: internal error code, arguments:]
ORA-19600: input file is datafile copy 0 () RMAN-10031: ORA-600 occurred during call to DBMS_BACKUP_RESTORE.SCANDATAFILECOPY RMAN> exit

YIKES!! ....anybody have an idea why this would happen??

Here is the backup script that is used each night (it's the same for all 3 databases minus the changes is ORACLE_SID and sub-directories):

#!/bin/sh
export ORACLE_HOME=/u01/app/oracle/product/8.1.7 export ORACLE_SID=ASTU
export ARCH_DEST=/u01/app/oracle/admin/$ORACLE_SID/arch/

rm /oracle_backup/$ORACLE_SID/*
$ORACLE_HOME/bin/rman <<EOF
set dbid=1337318309
connect target
connect catalog rman_cat/disco_at_rep1.ruppman.com run{
allocate channel d1 type disk;
backup database format '/oracle_backup/ASTU/%U'
(current controlfile);

}
sql "alter system switch logfile";
sql "alter system archive log all";
sql "alter database backup controlfile to trace"; sql "alter database backup controlfile to ''/oracle_backup/ASTU/astu_ctl''";
exit;
EOF
#

any and all help will be GREATLY appreciated. I won't be sleeping well until I know the backup process is truly ok.

Thanks

Chris
