You could also have done it this way, no expdp step required: impdp username/pwd schemas=SCHEMA1 network_link=DB_NAME directory=dpump_dir remap_schema=schema1:schema2 -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of VIVEK_SHARMA Sent: Thursday, May 17, 2007 2:45 AM To: John Darrah Cc: oracle-l@xxxxxxxxxxxxx Subject: RE: Change Schema OWNER of ALL Objects in 10gR2 ? ... SOLVED Thanks John for the valuable Advice. Since 2000 Objects are scattered across 55 Tablespaces, but of Total Data Size 8 GB only, I achieved the Data transfer from 1 Schema to Another thru expdp - SCHEMAS=OWNER1 / impdp - REMAP_SCHEMA=OWNER1:OWNER2 Cheers ________________________________ From: John Darrah [mailto:darrah.john@xxxxxxxxx] Sent: Wednesday, May 16, 2007 3:09 AM To: VIVEK_SHARMA Cc: oracle-l@xxxxxxxxxxxxx Subject: Re: Change Schema OWNER of ALL Objects in 10gR2 ? transport tablespace fromuser touser might work create user owner2; alter all tablespaces with objects owned by owner1 to read only status; exp transport_tablespace=y tablespaces= the tablespaces w/ objects owned by owner1 drop tablespaces imp transport_tablespace = y fromuser=owner1 touser=owner2 I'm not sure if this will work in your specific situation by its worth a look.

NOTE - OWNER2 does NOT exist in the Database. NOTE - Other / multiple schemas & respective Objects should remain unaffected. NOTE - Database is a Testing Database. Hence Downtime is NOT an issue. Qs Is Export , Import the the only way using 1 of the following? exp - OWNER=OWNER1 / imp - FROMUSER=OWNER1, TOUSER=OWNER2 , expdp - SCHEMAS=OWNER1 / impdp - REMAP_SCHEMA=OWNER1:OWNER2 Cheers **************** CAUTION - Disclaimer ***************** This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).
