Unfortunately, PeopleSoft sometimes uses those terms interchangeably. You have multiple PeopleSoft databases (schemas) in a single Oracle database. This is supported, but not recommended because of the additional complexity and lack of flexibility. And in your case it sounds like the shear size of the resultant data dictionary may also have a bearing. If you had only one PeopleSoft schema per database, then instead of refreshing schemas you can clone whole databases. If you are thinking of doing any performance testing on these refreshed schemas, then bear in mind that you have repacked the data in the tables, and rebuilt the indexes. Have the PeopleSoft tablespaces been created with a 1M uniform extent size (which is in the delivered DDL script)? A PeopleSoft application database exists in a single schema in an Oracle database.

Mine was a simple spool script created to drop all objects (except LOB and package bodies) from dba_objects for a schema. Nothing fancy in my script.

It takes us the same for 35K objects in the SYSADM schema. The drop user cascade command takes 48 hours (or so I have been told) Which script are you using for the drop objects as it sounds to be quicker than mine (which I will post tomorrow from work) John 45 minutes for 100K objects is quite good.

It can be any table with a BLOB column. Lets say it has following definition. CREATE TABLE table1 (COL1 BLOB); Gus,

As I don't want the Client to have any direct share to Server Directory.. I don't want to user to Upload the file to the server from their client machine, and ask somebody else to load it from there. I want the user to insert directly into the BLOB.... Is there any way to use this Procedure from the Client?? I tried, but it seems Oracle does not support client call to DBMS_LOB.
