Figure 17. Whole consistent backup, commandfile backup_offline_paris To guarantee that a database’s datafiles are consistent, shut down the database with the NORMAL, IMMEDIATE or TRANSACTIONAL options before making a whole database backup. To bring up the database in the desired state, we chose the sequence: shutdown immediate; startup force dba; shutdown immediate; startup mount; For TDP for Oracle environment variables in the allocate channel command: DSMO_NODE is set because we use a different node name to the TSM backup client. DSMO_AVG_SIZE is a size estimate used by the TSM server to reserve space on TSM storage. DSMI_ORC_CONFIG points to our dsm.opt file. DSMI_LOG points to our backup log directory - the default is the $ORACLE_HOME/dbs directory of the Oracle instance PARIS. The allocation of multiple channels is only possible when TSM node’s MAXNUMMP (maximum mount points allowed) is greater than or equal to the number of channels. 82 Backing Up Oracle using Tivoli Storage Management
The following is an explanation of various statements in our coding example: set maxcorrupt for datafile 1 to 0 causes Oracle to abort the backup process if RMAN detects corrupt blocks in the SYSTEM tablespace. In our database, we used AUTOEXTEND=ON for all datafiles. Datafile 1 is always used for the SYSTEM tablespace. backup full causes a whole database backup. filesperset 3 forces RMAN to include maximal 3 files in a backup set. A possible restore from a single datafile will be processed faster. format ‘%d%t%s%p’ creates a TSM low level name including database name/timestamp/backup set number/backup piece number tag ‘paris offline 20010316.1111’ is a user defined symbolic name which is assigned to backup sets. It makes it easier to address these backups in RMAN restore or change commands. alter database open finally makes the database accessible to users. 6.4.2 Archived redo log backup The next examples show how to back up archived redo logs. In both examples, the current log is archived before the backup archivelog is started. The first example uses only one log archive destination as input for the RMAN backup and two different channels to speed up the process. With the filesperset 20 RMAN creates up to 20 backup pieces in one backup set. The delete input option tells RMAN to deletes the archive logs on disk after a successful backup: Chapter 6.
