2596592 - Asynchronous initialization error 1166 preventing database backup - SAP ASE


  • Error 1166 is returned to the console when taking a database backup:

Msg 1166, Level 16, State 4
You cannot execute the command 'DUMP' on database 'my_db' because it was created with asynchronous initialization and it has not been fully initialized.
Retry the command later.

  • When checking the ASE errorlog, a message may be seen for a failed database initialization

Asynchronous database initialization terminated prematurely for database 'my_db'. 
Use DBCC DBREPAIR(my_db, async_database_init, start) to restart it if required as uninitialized pages will incur a small performance penalty when they are first referenced.
