Derby & Non-Derby

[Santosh Koti <Sa...@infosys.com>]

Hi  All,



I was testing my app with Derby DB , & then the same with Oracle, the no
of db updates (ejb)  is much faster  with derby.

What could be the reason ?



 Tranql or  my JDBC driver or Open EJB container. ??



Thanks,

Santosh.

First of all, you are using derby on same VM or by network?

If you are using derby on same VM, then this explain difference - shared 
memory comms is always fast than network.
Since Oracle (and other DBs) are not written in Java, they will use 
Network comms.
There is docs showing this diffs in HypersonicSQL too - in process 
execution and server based execution.


Best regards,

Richter
