| Error | ORA-01648 |
Description | 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. |
