Use

You want to create a copy of your database instance, for example, for test or development purposes, or to set up a standby database.

Prerequisites

·        The database instance that you want to copy has the database instance type OLTP or Archive, and the processor architectures of the source and target hosts are compatible.

·        The database instance that you want to copy has the database instance type liveCache. Both the processor architectures and the operating systems of the source and target hosts are identical, and you are using the same DB procedures on both hosts.

Procedure

Use the Database Manager for the following steps:

...

       1.      Make a complete data backup of the original instance.

       2.      Initialize an existing target instance, or install a new target instance for recovery.
The target instance must have the same database instance type as the original instance, and the same software version 7.x.

Caution

The target instance must not switch to the operational state ONLINE before you import the data backup from the original instance (step 5). If the target instance has already been ONLINE, reinitialize it.

       3.      Configure the data volumes of the target instance so that they have enough space for the import of the complete data backup of the original instance (10% larger than the complete data backup of the original instance, for example).

       4.      In the target instance, create a backup medium for importing data backups. The medium you use must be compatible with the medium that you used to create the complete data backup of the original instance.

       5.      Import the complete data backup of the original instance into the target instance.

Note

If using the Database Manager GUI, proceed as described under Restoring Without a Backup History.

       6.      Start the target instance.

       7.      Update the system tables in the target instance.

       8.      In the target instance, restore any indexes that are no longer up-to-date ( BAD INDEXES).
