Ishwar One priority might be to get to 9.2. There are reasons Oracle has given 9.0.1 a short decommission date. One idea would be to export with a SQL statement. This would reduce the size of your exports. Also, if you are mostly just adding new data (few updates), you may be mostly just interested in exporting the new data.

Dennis, Thanks for the confidence I totally agree with you about designing and everything else. Could there be a temporary solution to get successful exports until we embark on this project. we are in a 24x 7 environment. Rgds Ishwar. -----Original Message----- DENNIS WILLIAMS Sent: Friday, June 20, 2003 4:30 PM To: Multiple recipients of list ORACLE-L Ishwar I am fairly new to partitions myself and must relearn the commands each time I need to work with the partitions. So I will speak more to the philosophy of a DBA that doesn't like to end up in a jam. I get a bad feeling about hashing to get around an immediate problem. I also question the value of an export this large. Have you timed the re-import? It might take so long as to not be of practical value. My approach in this situation would be to first design how I want my system to be. Lay out the partitions I would like to have, etc. Then create a plan to get to the situation I want. Conduct tests to see what changes can be made in a reasonable time. First create a new partition that will take the newly arriving data so your problem doesn't continue to get worse. Then aim at creating new partitions one at a time that will split the existing too-large partition into smaller partitions in a manageable effort per partition. You may end up creating one each weekend for awhile. My theory is being DBA of a really large database is similar to being captain of a supertanker. You can't turn a large ship or a large database quickly. You must anticipate problems a long distance off. Dennis Williams DBA, 80%OCP, 100% DBA Lifetouch, Inc. [EMAIL PROTECTED] -----Original Message----- Sent: Friday, June 20, 2003 2:50 PM To: Multiple recipients of list ORACLE-L Hey Dennis: I created a range partition table with the last high_value being maxvalue. The partition key is partner_id (an incremental sequence). Now pmax (the last partition) has become very big and gives "snapshot too old.." while exporting. Ultimate Plan ============= I realize that the ultimate solution will be the split the partition pmax, into enough segments so that the new pmax has no data. Then at this point I will drop the pmax partition. Therefore when new partners come I will add partitions accordingly. Maybe ===== But I was thinking If I can make pmax into a hashed subpartition, it will also distribute the data reasonably. I dont have to have the segments separated by the partner_id because the data are not evenly distributed to the partners. partner_id , count(*) 1 4646545542 2 11164546466 ... and so on.. Thanks very much for your help. Ishwar -----Original Message----- DENNIS WILLIAMS Sent: Friday, June 20, 2003 3:10 PM To: Multiple recipients of list ORACLE-L Ishwar - What Oracle version. Just off the top of my head, I think that 8i only allows the subpartition to be hashed. What is your goal? Dennis Williams DBA, 80%OCP, 100% DBA Lifetouch, Inc. [EMAIL PROTECTED] -----Original Message----- Sent: Friday, June 20, 2003 12:00 PM To: Multiple recipients of list ORACLE-L Hey, Can anyone say if there is a way to breakup an existing partition into subpartitons. The partition contains data.
