We need to move schema from one tablespace to another tablespace.
we are going to use following method:
alter table <tab> move tablespace <new_tbsp>;
my question is do we need to disbale primary keys and foreign keys before move and enable them at end.
I need to prepare script to move all objects from one tbs to another tbs. Should I move all the objects individually using "alter table" Command. I got all the objects information using "DBA_SEGMENTS" view.
I have more number of tables,indexes in that tablespaces.
I can not use exp for tablespace backup.
"All data you create in this tablespace will be encrypted using an AES256 encryption key. You cannot encrypt an existing tablespace. To encrypt data, first create an encrypted tablespace, then use alter table move, CTAS or datapump import to move your data into the encrypted space. Remember to drop the old tablespace BUT not including datafiles. Use an OS schred program to remove the old datafile. If you are on ASM you may use the including datafiles option since you can’t schred files from the OS inside an ASM instance."
But i want to know why we should NOT drop the including datafiles, when dropping tablespace (so 'drop tablespace my_tbs including contents and datafiles'). So what option should we use when dropping tablespace?
Why we should use OS capabilities to remove the datafiles?
What happens if i remove the datafile when i drop the tablespace?
i am using 11.2.0.3.0 version of oracle. We are planning to move some ~40 tables/indexes to new encrypted tablespace as a part of TDE(transparent data encryption). Currently three tables are having size ~30GB and one having ~800GB other have <2GB in size. And tables/indexes are altogether placed in different tablespaces.
whether i should create as many no of encrypted table spaces as it was before as unencrypted tablespace? or I should create one encrypted tablespace and move all the tables/indexes into that?
Oracle version : 10g, 11g (applicable to both) Consider a schema named 'UNIVERSE' present in the database A running on Linux platform where this schema needs to be moved to another database B running on windows platform or AIX platform with no downtime provided and data needs to be consistent. Is this practically possible?

Now i want to delete this tablespace xyz.
I'm having issues with things disappearing from my database. I know what you are thinking, OK Crazy things don't just disappear. The only thing I can think of that could be a possible problem is the way the oracle server is set up. (For the record, I don't agree with this set up. I was like this when I started with the company and they don't want to change it "because it works").
We currently have 90 + schemas on the server all in one tablespace. So the server has a data tablespace and an index tablespace. Every schema shares those tablespaces. It gets much worse that this but I'm not going to get into it.
Do you think that this set up would cause things to become missing?
I have created my schema in SYSTEM schema way back accidentally by forgetting to specify the database tablespace. There is about 60 objects (tables, indexes, functions etc) and 6MB Of data.
What would be the best way migrate the schema to the tablespace I planned to put it into? .
One tablespace used in two different schemas ,in this case how much space used,free space and persentage of used in each schema level.
Example: USERS tablespace used in two different schemas HR,SCOTT. in this suche case to find the total size of tablespace, used and free space of each schema level.I used the below query not giving appropriate result.
SELECT TABLESPACE_NAME,
OWNER, round(SUM(BYTES/1024/1024),2) "Used Space in MB"
FROM DBA_SEGMENTS
where tablespace_name not in ('SYSTEM','TEMP','SYSAUX','EXAMPLE','UNDOTBS1')
group by tablespace_name,owner
order by tablespace_name
I have taken the tablespace export it came 2.1gb and for the same user i have taken the schema export it came 5.1gb
why their is a lot of difference in size?
I heard that USERS tablespace should not contain any other application schema objects.
If the above statements is true , why it should not contain other schema objects ?

I'm trying to generate a statistic, that shows me a weekly or monthly report over the traffic on a tablespace or a schema. Until now, I've worked with the
HIST_VIEW dba_hist_tbspc_space_usage
(I mean there is also one nearly called so for schema), but that view show me only the grow of a tablespace in a timeline of 1 week.
But that would not be the hole traffic. Because SELECT statements will nothing do on the grow of the tablespace but it generates traffic. In that case it wouldn't be so important, if it is more tablespace or schema sided because at this database each tablespace has it's own schema and timeline would be nice if it is weekly or monthly.
I want to import a schema from one database schema to another schema b from db STBTST to STATST and from schema CMSSTAGINGB to CMSSTAGINGA
I first want to test this to my own schema (mvanmannekes) CMSSTAGINGA is filled at the moment.
So i've created a dump from STBTST-CMSTAGINGB For importing im using this statement:
impdp mvanmannekes/password schemas=cmsstagingb remap_tablespace=cmsliveb_data:cmslivea_data

How to import dump into specific tablespace instead of default tablespace users.

i have a tablespace which contains 121 datafile(max limit reached) as a dba what we have to do?
creating a new tablespace with a datafile and assign the users to the current tablespace which i created now.iif the above process is correct,after some time the tablespace which was filled up got freed up.now can i give the access to the users previous (i.e. freed up tablespace) and current tablespaces

My database is OLP system.
My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
A single master schema where many developers are accessing. all share same password.
now i would like to trace all the changes made by each users. so i create a individual users for all and grant permission to access that schema.do i have a possibility of auditing the changes did by each user for that particular schema
We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.
I would like to create a table in another schema(CBF) as already exist in my schema(TLC) without data but related indexes,synonyms and grants should be include.
How could I do this without using export import. I am using TOAD 9.0.1.
how to take all schema metadata export except one schema (scott)
can i use like EXCLUDE=schema:"IN('SCOTT')
I had done following steps,
schemas(toy,toys)
1) i open the session of toy schema
First i taken backup of table
create table bck20121103_himan as select * from himan;
Backup table is created.
After taking the Backup table
delete himan;(deleting the records)
2) i log in to another session(toys)
exp toys/toys@orcl file=20121103TOYs.DMP TABLES=(HIMAN) /* Particular table is taken*/
3) i log in to toy schema
imp toy/toy@orcl file=<dump file name> TABLES=(HIMAN) INDEXES=N IGNORE=Y
i tried the above statement it taken so much of time..
Later i tried
I log in to toy session
i rename the table with other name.
later i imported
imp toy/toy@orcl file=<dump file name> TABLES=(HIMAN) IGNORE=Y FULL=Y
it's successfully imported.
move the tables with data present in the user scott(full) to another schema named test. In my case scott is in user tablespace and for test schema i have created different tablespace named test_tbs.

how I grant access of one schema object to another schema. Currently I am using oracle 10g
A user is using an ad hoc tool similar to SQL Developer called PeopleSoft Application Designer.
He creates a connection to the db, then issues an alter session set current_schema = 'restricted_schema'. The connected user does not have direct privileges on the "restricted_schema" which they call SYSADM.
After changing the schema context in that manner he creates objects in SYSADM. A schema trigger is then fired and grants privileges on the new objects created in SYSADM. Doing the same in either SQL Plus or SQL Developer does not fire the schema trigger.
I think SQL Plus and SQL Dev are working as they should. Altering the session like that does not change your identity - just the schema context. But, when you examine v_$session, the connection with this other tool looks exactly the same as one from SQL Plus or SQL Dev when changing the schema context in the session.
Instead of trying to figure out what this other tool is doing, is there any way for that schema trigger to fire when using this process from one of our tools?
