I've
gone to using the thin driver exclusively, as (counter-intuitively, I know) it
performs better than the OCI driver. Plus it's easier to
port...
My application uses a database and
doesn't seem to scale well. What could be going on?
Oracle provides two types of database drivers: a
type-2 driver, called the OCI (Oracle Call Interface) driver that utilizes
native code, and a type-4 pure Java driver called the thin driver. In single
processor environments, the thin driver works somewhat better than the OCI
driver because of the JNI overhead associated with the OCI driver. On
multi-processor configuations, synchronization points within Solaris used by
the OCI driver become big bottlenecks and prevent scaling. We recommend using
the thin driver in all cases.
Is this actually the case? Does
anyone have more information on this?
Thanks,
Rick
