Finding and fixing synchronization problems

Problems with synchronization between PI MDB and AF come in two general categories: health status problems and security problems.

• Health Status Problems: The PI MDB to AF Synchronization tool shows the synchronization health status of each connected Data Archive server. When you show the detailed view on a particular Data Archive server, you see a more complete health status message. See List of health status messages for an explanation of the messages and instructions for handling them.

• Security Problems: PI AF and Data Archive use different mechanisms for authentication and access permissions. Because of the differences in the two systems, some security settings cannot be synchronized. This can lead to inconsistencies in MDB and AF access permissions. See Checking security synchronization for more information.

When synchronization problems arise, users typically experience the problem as a restriction in the ability to view or edit MDB. Another common symptom is that a user cannot view or edit the same content both in MDB and AF. See Troubleshoot synchronization for common symptoms and possible causes.
