Take a backup of the running database.
Set up the database dump in a test environment and test it for any issues.
For more information on setting up a database dump, go to the MySQL, SQL Server, and Oracle offical documentation.
Tip
Tip: We recommend you to test the database dump before the cleanup task as the cleanup can take some time.

Run the following scripts on the database dump. It takes a backup of the necessary tables, turns off SQL updates and cleans the database of unused tokens.

Once the cleanup is over, start the API Manager pointing to the cleaned-up database dump and test throughly for any issues.
You can also schedule a cleanup task that will be automatically run after a given period of time. Here's an example:

Code Block

language	sql
title	MySQL

USE 'WSO2AM_DB';
DROP EVENT IF EXISTS 'cleanup_tokens_event';
CREATE EVENT 'cleanup_tokens_event'
    ON SCHEDULE
      EVERY 1 WEEK STARTS '2015-01-01 00:00.00'
    DO
      CALL 'WSO2AM_DB'.'cleanup_tokens'();

-- 'Turn on the event_scheduler'
SET GLOBAL event_scheduler = ON;

Replace WSO2AM_DB with the name of your API Manager database in the above script.
