ORA-01648: log [string] is the current log of disabled instance [string] (thread [string])
Cause: An attempt to enable the thread failed after it was half completed. This log was left as the current log even though the thread is still disabled. Since a log switch cannot be done until the thread is enabled, the log can not be cleared or archived.
Action: Complete the thread enable by issuing the enable command again.
Error Type: ORA
