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.
After creating a migration analysis, you can add more SQL statements to it.
To add SQL to an Analysis
From the left pane, select the analysis in which you want to add the SQL.
Right-click and select Add SQL.
From the Add SQL window under the Select SQL to be added pane, check the SQL statements you want added.
Under the Select Scenario to include SQL pane, check the Scenarios you want the SQL added to.
Click OK to add the SQL, retrieve the query plans and re-execute the Scenario.
You can only modify the analysis name and description of a Migration analysis.
To modify an Analysis
Select the Analysis name you want to modify from the left pane.
Right-click and select Modify to open the Modify Analyzer window.
Modify the name and/or description.
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
Select the Scenario you want to modify from the left pane.
Right-click and select Regenerate.
From the Regenerate Scenario window, check the SQL statements whose current query plans you would like retrieved using the logon and parameter settings.
