Hi, Just a follow-up for you interMedia Text fans out there. The statement below worked for us to eliminate the ORA-1410 and ORA-600 [12700] errors. Alter Table DR$<Our_CLOB_Index$R Modify LOB (Data) (Cache); The "interMedia Text Performance FAQ" on TechNet recommends (Cache Reads) to speed up queries. That worked for us until we started deleting selected Documents. Now (Cache) gives us the large query performance boost we wanted, albeit with a significant, though acceptable (30-40%), increase in time taken for index re-syncs. Hope this helps someone.

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.
