Shrinking 7 TB tablespace to 1 TB in 3 hours - how?

edited Mar 1, 2010 12:51AM in Database Administration (MOSC) 9 commentsAnswered
 Hi,
I have a 8 TB database, mostly one 7 TB tablespace (lots of 32 GB datafiles) which contains LOBs.  90% of LOBs are to be deleted from database and we will then want to reduce size of empty-ish datafiles.  The client wants to do this in a 3 hour downtime window, if at all possible.  At any rate, minimising downtime is a priority.  Any ideas beyond export/import?

Database is 10.1.0.5 EE on Solaris 10. No ASM, no RAC, no standby. 

Thanks.

Howdy, Stranger!
