It turns out there is a bug in IBM's TCP/IP stack. after looking at this and setting this $ su - db2inst1 $ db2set DB2TCPCONNMGRS=1 To quote " the difference was UNBELIEVABLE !!!". Thanks Eric. Many AIX applications use IBM Db2 as the database, while others use Oracle, IMS DB, Informix, or other databases.

Db2 supports hypervisors fully embedded in hardware/firmware as long as operating system requirements are met. Some examples are systems equipped with Power Hypervisor, VMware ESX 3i, or Hitachi Virtage. Note: Any enhancements in hypervisor function that come in the form of separate software are not included in the definition of Hardware Embedded.
