Installation and Configuration

Configuration

This makes it possible to carry out a recovery more rapidly, or to carry out a point-in-time recovery without having to read in the redolog files, since the existing redolog files can be used.

AMON_INTERVALL

The parameter AMON_INTERVALL determines the time interval (in seconds) at which the archiving monitor is induced to compare the current number of accrued offline redolog files with the value of AMON_MAX_LOGS.

MIRROR

With this parameter you define whether the offline redolog files will be backed up twice by using mirroring. The following parameter is to be set only if your answer is y(es).

AMON_MIRROR_SERVER

Here enter the name of the NetWorker server that should control the backup of the optional second NetWorker backup group. Additionally with this para- meter a name is defined for the corresponding backup group. You may change this name later on, if necessary (see “Parameters with Expert Mode”).

If there is no entry for AMON_MIRROR_GROUP and

AMON_MIRROR_SERVER in the dbo${ORACLE_SID}.init configuration file no mirrored backup will be performed.

For the mirrored backup being activated by using AMON_MIRROR_GROUP und AMON_MIRROR_SERVER the backed up redolog files will only be dele- ted if both redolog backups have benn completed successfully.

SEND_MAIL_TO

You can use this parameter to specify a mail address to which the list of backed up redologs/tablespaces should be sent.

AMON_WATCH_DELAY

Period of time (in seconds) after which AMON_WATCH_DOG_CMD (see next parameter) should be called if the backup or mirror backup of the redolog files has not been performed.

AMON_WATCH_DOG_CMD

Command to be executed if the backup or mirror backup of redolog files fails or if the backup was not ended after AMON_WATCH_DELAY seconds.
