Changing the Log Mode from SINGLE to DUAL

Use

You can change the log mode for the current database instance.

Prerequisites

The database instance may be in any mode.

The current log mode is SINGLE.

Note

You can only change the log mode if the DEMO variant of the current log mode is deactivated (Deactivating the DEMO Variant of a Log Mode).

Procedure

Under New LogMode select option DUAL to mirror the log devspace.

If a mirror devspace has not already been defined for the log devspace, you must do this now:

Select the log devspace for which you want to define a mirror devspace, and choose Edit.
Under Mirrored, define the path and the type of the mirror devspace.

To integrate the mirror devspace in the database instance, you must restart the database instance. If you are not in OFFLINE mode, select the option
Restart Database and reintegrate mirror devspaces implicitly after LogMode change.

Confirm your entries.

Choose LogMode ® Change LogMode.

Result

The new log mode DUAL is displayed as the current log mode.
