ORA-00600: internal error code, arguments: [13011], [7907] on SYS.DBMS_AQ_INV

Hi all,

So a couple weeks ago I was facing the following on a client environment. It was appearing every 10 mins on alert.log:

ORA-00600: internal error code, arguments: [13011], [7907], [12679954], [1], [13461738], [0], [], [], [], [], [], []
ORA-01403: no data found
ORA-06512: at "SYS.DBMS_AQ_INV", line 1248

I could find several references to ORA-600 [13011], always related to some internal corruption. As this table is related to Advanced Queueing, decided to check on Scheduler Job table structures:

SQL> analyze table SYS.SCHEDULER$_EVENT_LOG validate structure cascade; 

Table analyzed. 

SQL> analyze table SYS.SCHEDULER$_JOB_RUN_DETAILS validate structure cascade; 
analyze table SYS.SCHEDULER$_JOB_RUN_DETAILS validate structure cascade 
ERROR at line 1: 
ORA-01499: table/index cross reference failure - see trace file

SQL> analyze table SYS.SCHEDULER$_JOB_RUN_DETAILS validate structure;

Table analyzed.

Also on the generated trace file:

2019-03-01 22:26:37.736 
SESSION ID:(39.32751) 2019-03-01 22:26:37.736 
CLIENT ID) 2019-03-01 22:26:37.736 
SERVICE NAME:(SYS$USERS) 2019-03-01 22:26:37.736 
MODULE NAME:(sqlplus.exe) 2019-03-01 22:26:37.736 
CLIENT DRIVER:(SQL*PLUS) 2019-03-01 22:26:37.736 
ACTION NAME) 2019-03-01 22:26:37.736 
CONTAINER ID:(1) 2019-03-01 22:26:37.736 
Table/Index row count mismatch 
table 273184 : index 275017, 1832 
Index root = tsn: 1 rdba: 0x00c0128a

So ANALYZE on table SCHEDULER$_JOB_RUN_DETAILS fails with CASCADE but succeeds without CASCADE. This means that there is a problem with one of the index of this table. It has gone out of sync with the table.

SQL> select 'alter index '||owner||'.'||index_name||' rebuild;' from dba_indexes where table_name='SCHEDULER$_JOB_RUN_DETAILS';

alter index SYS.I_SCHEDULER_JOB_RUN_DETAILS rebuild;

SQL> alter index SYS.I_SCHEDULER_JOB_RUN_DETAILS rebuild online;

Index altered.

After this, error solved and no more recurrence of that ORA-600.

Also note I couldn’t find any document about this on MOS, so this is kind of exclusive by now. 🙂
