Also, a bigger question, why was another schema able to create indexes in SYSTEM. Was it granted the resource role? If yes, revoke the unlimited tablespace privilege from it. And also check the default tablespace to ensure it's not SYSTEM.

Check dba_free_space to find out how much free space you have freed up for the SYSTEM tablespace.

Then you can do:

SQL>alter database datafile 'path_to_system_tablespace' resize 800m;

800m is just an example.

This will work if the space you freed up are towards the end of the datafile, not in the middle.

guys,

one of my instances here...

has SYSTEM tablespace of size 25G (with one datafile). it has lot of indexes used by an application. the total size of indexes in SYSTEM tablespace is 21G.

this was done by someone else and now they want me to :

1)drop some un-used indexes in SYSTEM tablespace.
2)move the remaining indexes to some other tablespace.
3)and make the SYSTEM tablespace smaller.

all they want is to free disk space.

i can move the index to some other tablespace by <alter index ......rebuild>.

even if drop the indexes ....the space occupied by the index in the SYSTEM tablespace is cleared but the datafile does not get smaller.

but how do i make the file smaller ?

should i exp and imp the whole DB ?

the ENV is 8.1.6/win2k .
this is quite urgent.plz respond quickly.

Regards,
Prem.
