Insert performance

[Rick Stephenson]

Does anyone have any idea how to improve performance for multiple inserts into a table that uses a sequence generated primary key?   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,   Rick Stephenson Oracle Database Administrator Ovid Technologies, Inc.
