We have a large (6+ TB) OLTP database, which currently has 2300+ datafiles. A while ago, we stopped adding datafiles and were exclusively extending them. But we are wondering how far we can/should go, with the size of individual data files. Currently about 30% of the datafiles are at 8 gig. BTW - this particular application resides on VMS. Any ideas/thoughts/comments would be appreciated. Thanks. Dan Hubler Database Administrator Aurora Healthcare daniel.hubler@xxxxxxxxxx
