Starting an Oracle Snapshot Database Instance

If you created a snapshot using the Database FlashSnap feature, you can start an Oracle snapshot database instance from the secondary host via the GUI. This is the equivalent of cloning the database from the primary host. You must know the UNIX user name and password of the database owner and there must be an existing snapshot.

For more information on the Database FlashSnap feature within the GUI, see Managing Snapshots with Database FlashSnap.

Prerequisites

• Make sure you have enough space to create a clone database on your system.
• You must have an existing snapshot.

  To start an Oracle snapshot database instance

1. Click the Oracle Databases icon in the object tree. (You may need to expand the tree view to find the icon.)
2. Select one of the following methods to start the snapshot database.
   • From the menu bar, select Oracle > Start Up Snapshot Database.

   or

   • Right click the Oracle Databases icon to bring up a pop-up menu. Then click Start Up Snapshot Database.

   The Start Up Snapshot Database wizard screen is then displayed.

3. In the "connect as" section, enter the local Oracle home information. Then, enter your UNIX user name and password.
4. For the primary database information section, enter the Oracle SID information.
5. Select whether you are creating the database or restarting the database by clicking the appropriate radio button.

   Select "Startup database" if you are starting a new snapshot database based on a snapshot. Select "Restart database" if you are restarting a snapshot database that has already been created.

6. For the snapshot database information section, enter the new Oracle SID, Snapplan file, VxDBA volume name, Snapshot disk group name, and Relocate path in the appropriate fields.

     Note    To start an on-host snapshot database, the Relocate path is required. To start an off-host snapshot database, the VxDBA volume name field is required. You can obtain this information by viewing the details after you create a snapshot. If you did not retain the information from the snapshot creation, you can use the dbed_vmchecksnap command or use View Log via the GUI to retrieve the information. For more information, see Creating and Working with Storage Checkpoint Allocation Policies Using dbed_ckptpolicy.

7. Click Start Database.
8. At the confirmation prompt, click Yes to confirm that you want to start the database.

   If the snapshot database was successfully started, you will receive a confirmation message. Click on OK to continue.
