Rolling forward selected table spaces

Use the Table spaces page of the Roll-Forward Database notebook to specify that you want to roll forward a subset of the table spaces.

Notes:

1. Before you can do forward recovery, the database object must already be in the roll-forward pending state (which you can specify when you restore the database or database partition), and you must have the database logs.

2. If time considerations dictate that you must roll forward a subset of the table spaces when you would prefer to roll all of them forward, you can roll forward only those table spaces required to make the database functional, then, when you have the time, you can roll forward the remaining table spaces.

Before you begin...

To roll forward selected table spaces:

1. Open the roll-forward notebook:

   • Open the Roll-Forward Database notebook.

   • Open the Roll-Forward Database Partition notebook.

2. On the Roll-Forward page, specify the type of roll-forward recovery that you want:

   • Roll-Forward to the end of the logs. All changes recorded in the logs are reapplied to the database.

     Note:

     If you need to restore a table space on a specific database partition you can perform roll-forward recovery on it to the end of the logs to bring it up to the same level as the table space on the other nodes.

   • Roll-Forward to a point in time. Changes in the logs up to and including the date and time indicated are reapplied to the database or database partition.

     Note:

     In a partitioned database environment, if you want to roll forward a table space to a point in time, you must restore the table space partition at each database partition that contains a portion of the table space, and roll forward each table space partition individually to the same point in time. This ensures that the table space is consistent at each node.

3. On the Roll-Forward page, clear the Leave in roll-forward pending state check box to turn it off. This makes the database or database partition usable immediately after the roll-forward operation. (By default, this check box is on).

4. On the Table spaces page, click on Use selected table spaces only.

5. On the Table spaces page, specify the table spaces that you want to roll forward by ensuring that they are listed in the Use table spaces box. Use the >>, >, <, << controls to build the list of table spaces that you want to roll forward.

6. On the Options page, select one of the Process while radio buttons, either Online or Offline. Offline is the default.

7. Click on OK to begin the roll-forward operation.
