This error can have several causes, including:
- During server start
-up, the database was not accessible. Verify that the database is running and is accessible to the AR System server.
- During operation, this error can occur if AR System needs to contact an external database that is not accessible, for example, when opening a view of an external table.
When ARERR 551 occurs, the database error is usually captured in the AR System SQL log. To help diagnose the cause of this error, generate client-side
ARAPILOGGING (when the error is generated from user interaction) and server API and SQL logging to identify the call that failed and the specific database error message.
