Hi All,

The query is,

"When we create a java stored procedure in oracle 11g, will JVM load the java program each time or it will load only once when it is created". May i know how to confirm the same.

Thank you in advance Smile

It is loaded the first time it is used and after each time it has been removed from the memory due to lack of space.

By "load" do you mean read into memory? Stored Java procedures are cached in the library cache of the shared pool, as are SQL statements and stored PL/SQL. THe library cache is managed by an LRU (Least Recently Used) algorithm. You can see what is cached right now by querying v$db_object_cache.
