Oracle 9i and Shrink Bloated Datafiles

Tags: oracle, shrink, 9i, tablespace, datafile
I have a DB (Oracle 9i) which has recently been growing at an exponential rate.  We finally found the source of the problem and have run the appropriate scripts to clear out the garbage data but now need to reclaim the ‘Whitespace’ in the data files.  I know that I can do an export of the DB then drop it and re-import but I was wondering if there is an easier way of dealing with this?  The problem is isolated to a single Tablespace / Datafile.

Thanks!

Just a try:

you can try alter table shrink space,
after coalesce the bloated  tablespaces
then then resize datafile.

suhong,

I don't have any 9i around to verify but I believe the 'shrink space' command is new to 10g.
 
 
Comment by gvsbnarayana
Shrink space is 10g command.. not in 9i.
You can use the MOVE clause of alter table .. to move the table to a different tablespace temporarily and then back to the original tablespace.
You can use alter table <table_name> move tablespace <tablespace>
This SQL will invalidate the indexes on the table and you will need to rebuild the same
