Hello,
I'm confused about making daily incremental RMAN backup of a database runnig on Oracle RAC 10.2.0.3 on two Solaris nodes and ASM.
Databases cannot be stopped for backup and point in time recovery is needed.
Please correct me if I am doing wrong:
1) Backup must be Weekly database Level 0 and Daily database Level 1 is appropriate.
2) Is best to use a Flash Recovery Area (FRA) - I've setup one on a separate ASM volume. I have enough space to do the backup on FRA.
3) I am confused about the number channels I need to use. Do I need to use separate RMAN backup channels for each node or I can just leave the default:
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
4) Below are the RMAN scripts I plan to use for
- Weekly database backup Level 0:
#!/usr/bin/ksh
echo BACKUP FULL: $ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup incremental level 0 database TAG bkp_level0_200906010;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
}
exit;
eof
- Daily database backup Level 1:
#!/usr/bin/ksh
echo BACKUP INCREMENTAL: $ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup incremental level 1 database TAG bkp_level1_20090611;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
}
exit;
eof
I'm I doing things wrong?
