Oracle11gR2 rhel5 64bit
Hi All,
For some reason, my full online database backup keeps failing. The database size is approximately 4TB. I am using the following commands to backup the database:
run {
sql 'ALTER SYSTEM SWITCH LOGFILE';
ALLOCATE CHANNEL t1 DEVICE TYPE DISK;
BACKUP filesperset=10 FULL DATABASE FORMAT '/mnt/oracle/backups/PROD/FULL/dbfiles_%d_%U_%s_%T';
BACKUP CURRENT CONTROLFILE FORMAT '/mnt/oracle/backups/PROD/FULL/ctrlfile_%d_%U_%s_%T';
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
BACKUP ARCHIVELOG ALL FORMAT '/mnt/oracle/backups/PROD/FULL/archlogs_%d_%U_%s_%T'DELETE INPUT;
RELEASE CHANNEL t1;
}
The backup runs for several hours, and then it fails with the following error:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on t1 channel at 12/07/2010 21:06:27
ORA-19510: failed to set size of 3257661 blocks for file "/mnt/oracle/backups/PROD/FULL/dbfiles_PROD_06lv04nc_1_1_10246_20101207" (block size=16384)
ORA-27045: unable to close the file
Linux-x86_64 Error: 5: Input/output error
Additional information: 4
Note, that '/mnt/oracle/' is actually a windows share. I have never had issues with this....I am currently running oracle backups to a windows share with no issues. I think that the error might be related to the sheer size of the backup/database, perhaps?
Oracle support seems to be stumped on this too.
Thanks for your help.
