I have already bumped that up quite a bit as well, but I still get many waits.

Thanks,

Does anyone have any idea how to improve performance for multiple inserts into a table that uses a sequence generated primary key?

Is the sequence cache set to an appropriately large value?

I have approximately 6 concurrent inserts per second into this table which causes the primary key index to become a hot block. This in turn causes "buffer busy waits".

I have increased initrans, but am not sure where to go from here

Any ideas would be appreciated,

Thanks,
