How to setup RMAN catalog for Backups

• Select database for catalogue
• Create catalogue owner RMANC, default tablespace TOOLS
• Grant RECOVERY_CATALOG_OWNER role to RMANC
• Run the RMAN executable, being the same version as the catalogue database codeset and connect to the catalogue as the RMANC user
• Issue the CREATE CATALOG command

At RMAN repository Database

SQL>   create user rmanc identified by xxxxxxxx Temporary tablespace TEMP Default tablespace TOOLS quota unlimited on TOOLS;
SQL>   grant RECOVERY_CATALOG_OWNER to RMANC;
%RMAN catalog RMANC/xxxxxxxx@catdb
rman>   CREATE CATALOG

At Target Database which need to be backed up thru RMAN. Before registering a target database, create the target rman user in the target database.

SQL>   connect / as sysdba
SQL>   create user RMANT identified by xxxxxxxx
Default tablespace TOOLS
Temporary tablespace TEMP;
SQL>   grant SYSDBA,CREATE SESSION to RMANT;

Initialisation Parameters : To improve backup performance following parameters must be set….

BACKUP_TAPE_IO_SLAVES = TRUE
For 8i
LARGE_POOL_SIZE = (4 *
<number> *
DB_BLOCK_SIZE *
DB_FILE_DIRECT_IO_COUNT *
<level>
) +
(4 *
<number> *
<size>
)

For 9i
LARGE_POOL_SIZE= <number>*
(16MB +
<size>
)

The size of a tape buffer is determined by the RMAN parameter BLKSIZE.
BLKSIZE is OS dependant, but performance benefits can be made by explicitly setting it higher. 4M seems to offer improved performance. When testing a new backup, try differing values, in conjunction with the above calculation for LARGE_POOL_SIZE, to determine the optimal setting.

Net Requirements
RMAN requires a dedicated server connection to the target database.

Targetdb_rman.domain =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=TCP)(HOST=host)(PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=dbname.db_domain)(SERVER=DEDICATED))
)

The above should be configured on both the target and catalogue servers. The server hosting the target database also requires a Net configuration for the catalogue database, as this is where the RMAN commands are normally issued.

Database registration: To register the target database, issue the following commands.

rman TARGET  rmanc/xxxxxxxx@targetdb  CATALOG rmant/xxxxxxxx@cataloguedb
rman> REGISTER DATABASE;
To check successful registration, issue the following command whilst still in RMAN;
rman> REPORT SCHEMA;
Report of database schema
