It’s been more than 4 years since I have had to work with RMAN backup. Previously, sysadmin has been managing database backup using split mirror technology.
Now looking at RMAN from a different angle, calling RMAN scripts from the command line, similar to SQL scripts.
nohup rman @bkupinc0.rman > /dev/null 2>&1 & — Important not to forget @
[oracle@lax:db01]/home/oracle $ nohup rman @bkupinc0.rman > /dev/null 2>&1 & [1] 5643 [oracle@lax:db01]/home/oracle $ [1]+ Done nohup rman @bkupinc0.rman > /dev/null 2>&1 [oracle@lax:db01]/home/oracle $ nohup rman @bkupinc1.rman > /dev/null 2>&1 & [1] 5669 [oracle@lax:db01]/home/oracle $ [1]+ Done nohup rman @bkupinc1.rman > /dev/null 2>&1 [oracle@lax:db01]/home/oracle
Script: bkupinc0.rman
$ cat bkupinc0.rman
spool log to bkupinc0.log
connect target;
show all;
# maxopenfiles: ASM/striped 1; else 8
# 1 channel per tape drive for tape backup
run {
set command id to "INC0";
set controlfile autobackup format for device type disk to '/oracle/backup/%d_%F';
allocate channel d1 device type disk format '/oracle/backup/%d_%I_%T_%U.inc0' maxopenfiles 1;
backup as compressed backupset
incremental level 0 check logical database
filesperset 1 tag="INC0"
include current controlfile
plus archivelog not backed up 1 times
filesperset 8 tag="INC0"
;
backup spfile tag="INC0";
}
exit

I like grouping all backup process into one tag and might get some disagreement on this since I have seen implementation having separate tag for DB, ARC, CF, etc…
If you look at LV column, A=archivelog, 0=incremental level #, F=file backup.
