Starting RMAN

Use RMAN to back up and restore an Oracle database.

About this task

In this example, the catalog database contains a registered target database. Start an RMAN session with this command:

$>  rman target xxx/yyy@target rcvcat aaa/bbb@catalog 
  cmdfile bkdb.scr msglog bkdb.log

RMAN starts in the sequence shown.

target xxx/yyy@target: connect to target database 
using user xxx and password yyy with connect string target
rcvcat aaa/bbb@catalog: connect to catalog database
using user aaa and password bbb with connect string catalog
cmdfile bkdb.scr:  run bkdb.scr script
msglog bkdb.log:  log the output messages in bkdb.log

Tip: In the example, RMAN creates a log file, bkdb.log, in the current working directory. If an error occurs, the error stack is logged to the log file.

Attention: For backup and restore operations in a Linux™ environment, Oracle recommends that the Oracle LD_ASSUME_KERNEL variable is set for the Oracle user. For example:

LD_ASSUME_KERNEL=2.4.21; export LD_ASSUME_KERNEL

After a completed backup or restore operation, view the throughput rate and encryption status for a backup object in the IBM® Storage Protect server activity log file. Run the IBM Storage Protect server QUERY ACTLOG command in the IBM Storage Protect server administrative client window. A message similar to the following is displayed:
