Oracle Database Discussions

Hi there,

Currently we are having a single Oracle 11g instance. All our stored procedures are run on this database either directly from within the database (DBMS_JOB) or called externally from front-end java web apps.
The question is we now have to cater for scenarios where there will lot more avenues (other java apps) calling the stored procedure and we want to provision for such scenarios without impacting the performance or agreed upon throughput back to the calling application.

One option I read was about clustering (RAC) and how this can be configured at the database level to transparently cater to a huge volume of stored procedure calls to the database without affecting (requiring changes on the calling entities). So the java front end apps will only refer to a single database but Oracle RAC configured for the database will handle the heavy load scenario in seamless and transparent fashion across the clusters

We don't want to split the execution of one single stored procedure run into multiple process for performance we have that part covered with optimizing the queries of the stored procedure
but we want to provision for a scenario where multiple apps can spawn calls to the stored procedures simultaneously and the database is efficient about handling these parallel stored procedure invocations and does not overwhelm under the pressure of large volume of stored procedure run causing degradation of stored procedure runtime/response time.

Please provide your thoughts.
