Corba Client inside the DB

Question

Hello all
I tried to deploy the HelloWoworld Corba example into DB (Corba server inside the DB, Oracle 8.1.6). All works fine while client is outside of DB... Then I tried to load the client into the DB and created related stored procedure to call the "HellWorld" method, but got the exception: ORA-29532: Java call terminated by uncaught Java exception:<b>
org.omg.CORBA.OBJ_ADAPTER: Could not instantiate adapter:
java.lang.NullPointerException minor code: 0 completed: No
</b> So, is it possible to call the DB Corba object from within the same DB? What I should do to perform this?
Thank you,
Andrew

The 'Keep Pool' is part of the Shared Pool and is used to keep executable objects (procedures, functions, and packages) in memory. This can speed up loading and reduce parsing of these objects.
In the DBBlock Buffer Cache, you can have several areas. The size of these is determined by
DB_CACHE_SIZE and DB_nK_CACHE_SIZE
DB_KEEP_CACHE_SIZE
DB_RECYCLE_CACHE_SIZE
Which segments go into the various cache pools are determined by the 'STORAGE (BUFFER_POOL {DEFAULT | KEEP | RECYCLE } ) clause of the table or index create/alter statement.
The purpose of the KEEP pool seems to be to keep the table blocks in memory as much as possible (eg: frequently used lookup tables), whereas the RECYCLE pool is to flush it from the cache as quickly as possible (typically large, always scanned tables)
For more info, look for BUFFER_POOL in the SQL Reference at http://docs.oracle.com (not http://www.docs.oracle.com as someone suggested)
I reserve the right to change my mind on anything. Especially when confronted with facts that are better than the ones I use right now.
