Hi all: We are having an interesting issue with the exchange partition command in our shop. We are running oracle 9202 on AIX 5l. The exchange partition command used to take about 1 sec (or less) in our old environmen (oracle 81 Dynix 4.3.3). Now the same operation takes about a minute and creates a ton of IO. an Oracle rep said that this has to do something with the way exchange partition now treats primary and unique keys. Recently however a DBA on my team did 4 exchanges in a row between the same two tables. First one took about 45s and did a lot of IO. next one took almost no time and no IO (and it did move the data), the next one - again 45s and IOs, the fourth one - no time again. Does any one has any experience with this issue and may be can shed some light on it.
thanks gene __________________________________ Do you Yahoo!? SBC Yahoo!
