DROP them, I suppose.

What are you, actually, trying to do? Drop whose objects? Could you - instead of dropping objects - drop users (which would also drop all their objects so that might be faster than dropping objects themselves)?

Thanks for your reply.
Actually I exported one entire database into newly created database. Now I would like to make this database as it was before. I understand your point that dropping users will drop objects as well and it's easier, but the problem is when I had exported the database, I hadn't mentioned any schema and so all the objects are in the SYS schema I suppose. So, How can I do this please?

SYS objects are never exported nor imported.
During import the objects go to their original schema (unless explicitly specified another one on the command line).

I see. So, I think I can drop the users containing these objects I guess. Thanks very much for your help Michel.

Hi there, continuing with my previous topic, I removed my database at last and re-created it. Now, I re-created this database with the same name and when I checked the objects by issuing "Select * from tab", surprisingly the previous objects have appeared in this database as well. Why did this happen? I would like one fresh database, but need to put the same name. Please help.

How did you recreate it? What steps did you perform (mention all of them)?

With which user you issued "select * from tab" ?
If its sys/system and few other default schemas, there there will be same number of objects.

In addition with which user did you execute your select?
Are you sure these objects are not Oracle standard ones?

Thanks for your reply. I recreated the database using DBCA. I followed the normal steps as we create a simple database.

The user was sys. Yes, I am sure these objects are not the oracle standard ones as they are the ones that were created when I imported the entire database(As I mentioned earlier).

Use the following step if the time permits,

Connect as sys
1.shutdown immediate;
2.startup mount;
3.alter system enable restricted session;
4.drop database;
---------------------
5. startup nomount pfile='path to pfile'
6. create database (try manually)
7. shut immediate;
8. startup nomount pfile='path'
9. create spfile from pfile;

What did you import, exactly? If export file contains objects BEFORE you dropped them, import imported them back. Maybe I don't understand what you are saying, but ... perhaps you should really name all steps you took.

Thanks very much for replies. Let me first try to create one new database with the different name so I can check if I still get the same objects in the new one. Veeresh, I will try following your steps afterwards. Thank you guys.

One thing is not clear.. what is "I still get the same objects in the new one" ?
all the sys(oracle system) objects will be same. IT will not change, no matter how many databases you create. Smile
