You're correct in saying that your undo blocks are protected by your redo files. What type of operation are you performing on your table? I ask because only a small subset of commands support the NOLOGGING feature; the remainder will generate redo as usual.
If you're not using a syntax that supports NOLOGGING maybe you could adapt your job to adopt one. Alternatively you may find that you just need to optimise your redo log placement in order to handle the load. Regards, Mike Hately -----Original Message----- Sent: 29 January 2003 14:10 To: Multiple recipients of list ORACLE-L Mike, I asked it because I have a problem. Any insert data in UNDO tablespace generate insert in REDO Files. Is is correct ? When I execute a high procedure, many inserts in UNDO tablespace ocurres, so many inserts in REDO´s are genereate. I want to avoid this REDO´s generation. My tables and indexes are in NOLOGGING, but I high value of REDO are generate (100 MB each 20 minutes). It is desnecessary. Oracle 9i / NT -- Breno A. K.
