DBMS_METADATA is a very large PL/SQL package and it needs to get loaded into the shared pool. If you want it to execute then you will need to get the DBA to increase the shared pool. Also you may (on 9i and maybe on 10i) need to increase the Java pool.
It appears to me that they have changed the innards of the DBMS_METADATA and it no longer needs as much Java pool space.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
