Home -> Community -> Mailing Lists -> Oracle-L -> Re: reason behind Oracle and HP love affair
An interesting feature of HP which may make
them less desirable to Oracle -Unlike other
machines, the HP chips have no atomic
'compare and swap' call, and this could
make a big difference to efficiency in Oracle 9,
especially in the area of shared latches
Look out for contention on the CAS Latch, used to emulate this function in software on the HP port.
