I was getting ORA-600 [12700] when I upgraded a 734 text database to 817. Ended up having to apply the latest patchset, I think it was 8172, to finally fix the problem. Has something to do with buffer cache corruption when Intermedia is trying to sync the index. The index loses its pointer to the row. Never got the ORA-1410 though. I have no idea if they have a patch for 816. If you contact Oracle, they will want you to analyze the base table and all the indexes and send them the trace file on the ORA-600.

Hi,

8.1.6.0.0 on Win2k with interMedia Text index on table of 4 million CLOB documents. It's been in stable operation for over 8 months, with approx. 70,000 documents being added daily, approx. 10,000 deleted daily, and a sync of the index each day.

We started getting ORA-1410 "invalid ROWID" for Contains queries and ORA-600 [12700] errors in the Alert log. This happened a few days after we altered the DR$<index>$R table to Cache Reads for its Data LOB column. Metalink Bug 1668041 indicates that changing Cache Reads to just Cache for the DR$...$R table solved the problem for an 8.1.7. WinNT DB.

Has anyone else experienced this? I'm rebuilding the index now (for the 2nd time this week! - takes 7.25 hours) and want to know if this fix will work.

Thanks for any advice or suggestions.

Jack
