4. Prepare to Modify the Table

Before you modify the participant address column definitions in the Wgn3EventParticipant table, verify that no changes, or attempted changes, can be made to the table while the update is in progress. You therefore need to:

1. Stop the CA DataMinder infrastructure service on the CMS. To do this, run the following command:

   net stop wgninfra
   

   Note: We recommend that you also disable the service temporarily to prevent it from restarting automatically.

2. Verify that no other users are logged onto the CMS database.
