Keep in mind though that IDS 9.4 is going out of support in a year. As past of this migration you should be seriously considering upgrading to IDS 11.50FC3 or later. The last three major releases of IDS 10.00, 11.10, 11.50 each improved performance by 10 to 25% so if you are looking to improve your overall peformance, this is a good thing. > > > The major goal of this change is to have faster OLTP. > > Despite the fact of moving to newer and faster machines what else do we > have to keep in mind to achieve faster OLTP? > > Disk Configuration ………….?

Use RAID10, get as many spindles involved in the database as posslble. If possible isolate the root dbspace, logical log dbspace, and physical dbspace from each other and from the data dbspaces on separate disk structures. The database should not share disk structures with OS filesystems either. > Memory ……………………?
