Upgrade / Data Migration Fails

If an upgrade installation fails with the message with the app_setup.log error Connecting to database...>>>>> ERROR: OWSessionIDRDBMS : Failed to make database connection, the problem is that the database is not running on the host being upgraded. To cure this problem, manually start the database, and then re-try the upgrade installation. The following are the startup commands for the embedded database:

Windows:

net start mysql

You should see the following response in the shell where you execute this command:

The MySQL service was started successfully.

If you substitute the word stop for start in the above, these commands manually stop the database.
