Re: ORA-600 Error [Possible Data Loss]

Ian,

I was going to recommend to try exporting your problematic partition with direct=y, that way normal SQL query processing layer is bypassed in Oracle kernel & all data belonging to segment is read directly (thus hopefully avoiding the koxsisz1 crash) ... but I'm not sure whether varrays don't turn exp to conventional as is the case with objects and LOBs...

Tanel.

table archive_wave_i move partition SEP1103 tablespace CHANARCH_NLC_2003_09_DATA). The table was renamed to OLD_archive_wave_i once it was determined that no new varray data was accessible. My theory is that this is logical corruption of the data dictionary, but I have not worked out the particulars.

here either. Just a wild guess, try to move this partition to another location and select from it then (although koxsisz1 isn't a data layer error as far as I understand). Try to read using index if available, then using full hint etc..
