Suzy, Just more questions: Are your sure that this corruption has made it to the disk? It could be memory related. Can you export the table to /dev/null to double check the corruption? What do you get when reading that particular block using dba_extents?
- Kirti -----Original Message----- Sent: Monday, February 24, 2003 10:09 AM To: Multiple recipients of list ORACLE-L I recently inherited a 40GB 7.3.4 database (yes, it needs to upgrade). Last night I analyzed the tables and a corrupted block was found. I know which table and datafile it is, and it's the only table in the affected tablespace. The database is in archivelog mode so I can recover the datafile, but I am not certain when the block corruption occurred. There were no proactive measures in place to quickly report a corrupted block. So I assume it may have been there a long time, and was just found through analyze (tables hadn't been analyzed since Dec-2000). So my question is, if all backups contain the corrupted block, how would I copy all non-corrupted blocks from this table into a new table? Here is the trace file: ORACLE data block corrupted (file # 24, block # 57856) Dump file /dbms/ora00/app/oracle/admin/kana03aP/udump/kana03ap_ora_13163.trc Oracle7 Server Release 7.3.4.3.0 - Production With the distributed, replication, parallel query and Spatial Data options PL/SQL Release 2.3.4.3.0 - Production ORACLE_HOME = /dbms/ora00/app/oracle/product/7.3.4 System name: SunOS Node name: kanadb-co1 Release: 5.6 Version: Generic_105181-17 Machine: sun4u Instance name: kana03aP Redo thread mounted by this instance: 1 Oracle process number: 10 Unix process pid: 13163, image: oraclekana03aP *** 2003.02.24.02.49.42.000 *** SESSION ID:(24.1317) 2003.02.24.02.49.41.000 *** Corrupt block dba: 0x6000e200 file=24. blocknum=57856. found during buffer read on disk type:0. ver:0. dba: 0x00000000 inc:0x00000000 seq:0x00000000 incseq:0x00000000 Entire contents of block is zero - block never written Reread of block=6000e200 file=24. blocknum=57856. found same corupted data -- -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Deshpande, Kirti INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
