Something Strikingly odd with Oracle: DB with Two ‘Current’ log-files!!

Posted by FatDBA on January 8, 2014

Something real uncanny happened with one of our databases recently: There were 2 log-files with CURRENT status: Strange right!!!

SQL> select GROUP#,SEQUENCE#,BYTES/1024/1024 as SIZE_MB,MEMBERS,STATUS from v$log;
GROUP#  SEQUENCE#      SIZE_MB    MEMBERS STATUS
———- ———- ———- ———-   —————
1       15651       50          2 INACTIVE
3       15653       50          2 CURRENT
2       15652       50          2 CURRENT
4       15650       50          2 INACTIVE

Found the ‘Notorious’ Generic error ORA-600 in alert log :
ORA-00600: internal error code, arguments: [3705], [1], [3], [2], [8], [], [], []

We had to perform point-in-time recovery up to 15652 sequence and we were all good.

Hope That Helps
