Define indexes to optimize access to database columns. An index can contain one or more database columns.
NOTE: For tables that you create using the Schema Extension program, indexes are automatically created for the primary key column and the object key column (XObjectKey).
To create a new index in the Schema Extension
-
Start the Launchpad and log in to the One Identity Manager database.
-
Open the Launchpad and select the One Identity Manager Schema Extension entry. This starts the Schema Extension program.
-
Click Next on the start page.
-
On the Database connection page, check the connection credentials for the One Identity Manager database.
-
On the Select method page, select Create index
-
On the Extend Table page, under Table, select the table for which you want to create an index.
-
On the Create index page, define the columns for the index definition.
-
Click the 
button.
This opens a dialog box where you can define the columns for the index. You can see all the columns in the table on the right-hand side of the dialog window. The columns on the left-hand side of the window belong to the index.
-
Enter the name of the index in the Index name input field.
A name is already suggested. You can change this as required.
-
On the right-hand side of the dialog window, select the column you want to add to the index.
-
Use the 
button to add the column to the index.
Change the order of the columns in the index definition as required or remove a column from the index using the relevant button.
-
Click OK.
NOTE: You can delete custom schema extensions only on databases with the Test environment or Development system staging level. It is not possible to transport the changes.
To remove custom schema extensions in the Schema Extension
-
Start the Launchpad and log in to the One Identity Manager database.
-
Open the Launchpad and select the One Identity Manager Schema Extension entry. This starts the Schema Extension program.
-
Click Next on the start page.
-
On the Database connection page, check the connection data for the One Identity Manager database.
-
On the Select method page, select Remove extensions.
-
On the Remove extensions page, select the custom schema extension that you want to remove.
-
To remove a custom table, select the table in the Table list and enable the Remove whole table option.
-
To remove custom columns, select the table in the Table list and select the columns under Columns to remove.
-
Click Next.
-
Confirm the security prompt with Yes.

For initial access to the schema extensions using One Identity Manager tools, select the permissions groups that contain the permissions for the schema extensions. After you have committed all the changes in the database, you can grant additional permissions through the Permissions Editor in the Designer. For more information, see the One Identity Manager Authorization and Authentication Guide.
