Recovering a Damaged Devspace 

Use

If you are running the log spaces of a database instance in mirrored form, and a log devspace fails while the database is running, there are functions available that enable you to recover the failed devspace.

Entries that were written to the intact devspace only while the damaged devspace was out of action are not copied.

Note that the mirrored log devspace is only secure once the recovered devspace is operating again. You should therefore backup the log entries that only exist once using a log backup (Backing Up the Database Instance).

Prerequisites

You have the DBM operator authorization Recovery.

You are operation the database instance with mirrored log devspaces. (LOG_MODE: DUAL).

You have opened a utility session.

You have executed the command for restoring a database instance.

Syntax

recover_devspace <dev_no> [<dev_mode>]

<dev_no>

Number of devspace

<dev_mode>

Here, LOG is the only possible entry.

This command returns the damaged devspace of a devspace pair to operation.
