Roll Back Changes to Configuration Parameters

Rollback Changes to Configuration Parameters

The Migration analysis connects to the database you are migrating to and first executes the configuration parameter changes that you have selected on your database. Then it retrieves the query plan for each SQL statement that you have selected for your analyzer. When you set up the individual scenarios, you determine if you would like the configuration parameter changes rolled back or to leave them set on Adaptive Server.

If you do not have the analysis process rollback the configuration changes, you can roll them back in any one of the following ways:

• In the tree pane (left pane), right-click the scenario name and select Go To Undo Changes.

• When you close the Migration Analyzer window, you are prompted to rollback the changes. Click Yes.

• In the tree pane (left pane), click the scenario name and select the Apply/Undo Changes button at the top of the right pane. Click next to the Undo Change pane.

You can make the changes permanent, in one of the following ways:

• In the tree pane (left pane), right-click the scenario name and select Confirm Changes. Click Yes.

• When you close the Migration Analyzer window, you are prompted to rollback the changes. Click No.

Regenerate a Migration Scenario

The Scenario can be re-executed using the exact same logon and configuration parameters. You can choose to retrieve the query plans for all SQL statements in the Scenario or select specific SQL to retrieve the query plan using the same logon and configuration parameters.

The function is useful if changes have occurred in the database environment, such as data volumes, that may change the query plans.

To regenerate a Scenario

1. Select the Scenario you want to modify from the left pane.

2. Right-click and select Regenerate.

3. From the Regenerate Scenario window, check the SQL statements whose current query plans you would like retrieved using the logon and parameter settings.
