System tablespace Vs User Tablespace

I'm running oracle 8i at Win2000 Server.
I have a database which have two SYSTEM tablepspaces and One User tablespace. Both SYSTEM Tablepspaces are near to FULL. Right now , The database performance is very poor. I can't understand why my SYSTEM tablespaces are growing fastly instead of User Tablepspace.

You cannot have multiple SYSTEM tablespaces... Do you mean that you have multiple datafiles associated with your SYSTEM tablespace?
Unless you assign users a default tablespace, objects that they create without specifying a tablespace will be placed in the SYSTEM tablespace, which is a bad thing. You probably have user objects in your SYSTEM tablespace.

Reasons to use separate temp tablespace for user tablespace

Hi,
I know that guideline says is not use system tablespace for user tables. But need i create for user tablespace separate TEMP teblespace or i can use same TEMP tablespace for all tablespaces?

Hi,
>>But need i create for user tablespace separate TEMP tablespace or i can use same TEMP tablespace for all tablespaces?
You can use one temp tablespace for a database , Temp tablespace usage are for sorting the data.
for more detail you can go with :Creating Tablespaces

Transport table from system tablespace to another tablespace

hi there,
how can we transport a table from system tablespace to another tablespace(example users tablespace)?

Assuming you are not trying to move any data dictionary tables.
Use alter table to move it,
ALTER TABLE my_table MOVE TABLESPACE USERS;
Rebuild index after move.
This will work on Oracle 9i and above.

Should Default Tablespace for User DIP be "SYSTEM" or "USERS"?

Oracle Enterprise Manager is giving me a warning about some non-system users who have a default tablespace of SYSTEM. One of the users is DIP. Is it OK for me to change the default tablespace for DIP to USERS, or should it remain SYSTEM?
Thank you,
Bill

To the best of my knowledge user DIP was created automatically by Oracle software when I upgraded my database from 8i to 10gR2. In my mind that means it is needed for managing some system function in the database. That is why I hesitate to change the default tablespace from SYSTEM to USERS.
If user DIP is tied to use of Oracle Directory Integration and Provisioning then I am not knowingly using the DIP account. I do not know what Directory Integration and Provisioning is and read about it only when researching this tablespace question. That being said, I expect that Oracle software does a lot of things internally that I am not aware of.
I was hoping someone familiar with user DIP could tell me that changing the default tablespace to USERS for this Oracle supplied account would do no harm.
Thank you,
Bill

Oracle 11gR2 Partition tables not creating in default user tablespace

Hi all:
Not sure if i'm missing something or overlooked but when i create a partition table in a user schema, it is not creating in the schema's default tablespace instead creating with no assigned to any and using SYSTEM tablesspace.
create user dgp identified by dgp default tablespace dgp temporary tablespace temp;
grant connect, resource to dgp;select USERNAME,DEFAULT_TABLESPACE from dba_users where username ='DGP';
USERNAME DEFAULT_TABLESPACE
DGP DG
select table_name, tablespace_name, partitioned from all_tables where owner='DGP';
TABLE_NAME TABLESPACE_NAME PAR
AUDITLOG_P2 DG NO
AUDITLOG_P YES
This is the partition script i used --i also gave the tablespace name:
CREATE TABLE dgp.AUDITLOG_P(
entry_time DATE,
username VARCHAR2(14),
groupname VARCHAR2(100),
ip VARCHAR2(15),
command VARCHAR2(15),
directory VARCHAR2(300)
PARTITION BY RANGE (entry_time)
partition P_PAST VALUES LESS THAN (TO_DATE('2010-01-01','YYYY-MM-DD')),
tablespace DG;
============
What is it i'm missing? Anything different with Oracle 11gR2 on the partition creations?
Thanks for your help..

TIP 01: Default User Tablespace in 10g by Joel Pèrez

Hi OTN Readers!
Everyday I get connection on Internet and one of the first issues that
I do is to open the OTN main page to look for any new article or any
new news about the Oracle Technology. After I open the main page of
OTN Forums and I check what answers I can write to help some people
to work with the Oracle Technology and I decide to begin to write some
threads to help DBAs and Developers to learn the new features of 10g.
I hope you can take advantage of them which will be published here in
this forum. For any comment you can write to me directly to : [email protected]
Please do not replay this thread, if you have any question related to
this I recommend you to open a new post. Thanks!
The tip of this thread is: DEFAULT USER TABLESPACE
Joel Pérez
http://otn.oracle.com/experts

Step 9: At the step 5 We changed the default tablespace of the database but there is an
important detail that We have to realize. That detail is the following : when you change
the default tablespace of the database. The users were using it are move to store its objects
in the new default tablespace but the objects that were stored in the original tablespace
remain there. Let's go to look at it:
Here We are connected to the database as system user
SQL> show user
USER is "SYSTEM"Let's go to get connection as new_user user in order to create a table
SQL> conn new_user/new_user@base1
Connected.
Creating a table in the schema NEW_USER
SQL> create table t1_new_user(c1 number);
Table created.As you can see that table is stored in the default tablespace assigned to the user new_user
SQL> select TABLE_NAME, TABLESPACE_NAME from dba_tables
2 where owner='NEW_USER';
TABLE_NAME                     TABLESPACE_NAME
T1_NEW_USER                    USERS1Now, We are going to perform the change at the database level regarding the default tablespace
SQL> alter database default tablespace TEST;
Database altered.Now, Let's go to see where the object is stored
SQL> select TABLE_NAME, TABLESPACE_NAME from dba_tables
2 where owner='NEW_USER';
TABLE_NAME                     TABLESPACE_NAME
T1_NEW_USER                    USERS1The object remain in the original tablespace assigned to the user new_user.
Here We can realize that the change was successful but the table still remain in the original
tablespace. You will have to move manually the objects to a new default tablespace.
SQL> select USERNAME, DEFAULT_TABLESPACE from dba_users
2 where username='NEW_USER';
USERNAME                       DEFAULT_TABLESPACE
NEW_USER                       TESTJoel Pérez

Grant previleges on tablespace to user.

Hai,
I have created one tablespace calles detail. I created one user student and set default tablespace of detail.
But while creating table in student user, it says 'no privileges on tablespace 'detail'.

Grant user student access to use all space in the detail tablespace:
ALTER USER student QUOTA UNLIMITED ON detail;
Prevent user student from using space in the system tablespace:
ALTER USER student QUOTA 0 ON system;

Problem Exporting 'USER' Tablespace Metadata

I am having problem using Data Pump Export to export the 'USERS' tablespace metadata.
When I make the USERS tablespace read only and run the Data Export job, the job aborts with "ORA-01647: tablespace 'USERS' is read only, cannot allocate space in it."
But then when I make the USERS tablespace read and write, the job aborts with "ORA-29335: tablespace 'USERS' is not read only."
I've been caught in this CATCH-22 for the 2nd day now, and I could really use some help. I'm on a Windows 32 platform running Oracle 10g, and here is a copy of the Data Pump Export script/command that I am running at the operating system prompt, which works fine for other tablespaces' metadata, like 'EXAMPLE':
$ expdp myusername/**mypassword* TRANSPORT_TABLESPACES=users TRANSPORT_FULL_CHECK=Y DIRECTORY=dtpump DUMPFILE=expdp_users.dmp logfile=expdp_users.log
Thanks!

Hi,
The problem is that the datapump creates a table called the master table. It creates this in the schema running the job. If this schema has a default tablespace that you are trying to transport, then this won't work. You will have to use a different schema that does not use the set of tablespaces that you are transporting, or alter the use that is running the datapump job to have a different default tablespace.
So, basically, datapump requires write access to the tablesspace that the user uses and transportable requires the tablespace to be read only.
If it were me, I would do this:
sqlplus username/password
alter user username default tablespace system;
exit
run your expdp command
sqlplus username/password
alter user username default tablespace orig_tablespace;
exit

Import Date Go to User Tablespace

i create one tablespace for one user and grant this tablespace or put default tablespace to user .but when import tables go directly in USERS tablespace. Please Advice Me How Make Solution.
Ahmed.

Where were the tables on the source database created. If they were created in tablespace users, then that is where they will be created on the target system. Just because you changed the default tablespace on the target database doesn't mean that is where the tables will be loaded.
If you want to move them to a different tablespace I think you need to make sure the old tablespace is not there.
If you use datapump, you can use the remap_tablespace parameter
remap_tablespace=old_tablespace:new_tablespace
This is not available on exp/imp.

USER TableSpace

Hello,
After I created an Oracle 9i database using Database Configuration Assistance, I noticed several tablespaces are created including SYSTEM, UNDO, and USER.
I created one permanent and one temporary tablespaces of my own (TESTTB1, TESTTEMPTB1). Then I created a user and assigned my new user to the tablespaces that I created (TESTTB1,TESTTEMPTB1).
During our application load test, I noticed the USER tablespace, the one that got created during database creation is being used a lot.
I am curious to know who is using the USER tablespace and for what kind of work? My understanding was that the Oracle uses the SYSTEM, UNDO and TEMP tablespaces.
Thank you,
Mitra

Try this script to find out who and what is occupying you USERS tablespace
select owner,segment_name, segment_type, tablespace_name,bytes,blocks
from dba_segments
where tablespace_name = 'USERS'

Users tablespace - datafile is 24.5 GB, only 1.2Gb used - What should I Do?

Hi All,
In my database I have users tablespace and its datafile is users01.dbf. File size is 24.5 GB, but used data is 1.2 GB. I got this information from OEM, see below image:
https://picasaweb.google.com/100555146235257804098/Oracle_a1#5759303022195932370
How can I free the unused 23GB space?
Just to let you know about my background knowledge, I am an OBI report developer.
Thanks!

Just in case if this also helps.
I got a query to find the free space from
SELECT /* + RULE */ df.tablespace_name "Tablespace",
df.bytes / (1024 * 1024) "Size (MB)",
SUM(fs.bytes) / (1024 * 1024) "Free (MB)",
Nvl(Round(SUM(fs.bytes) * 100 / df.bytes),1) "% Free",
Round((df.bytes - SUM(fs.bytes)) * 100 / df.bytes) "% Used"
FROM dba_free_space fs,
(SELECT tablespace_name,SUM(bytes) bytes
FROM dba_data_files
GROUP BY tablespace_name) df
WHERE fs.tablespace_name (+) = df.tablespace_name
GROUP BY df.tablespace_name,df.bytes
UNION ALL
SELECT /* + RULE */ df.tablespace_name tspace,
fs.bytes / (1024 * 1024),
SUM(df.bytes_free) / (1024 * 1024),
Nvl(Round((SUM(fs.bytes) - df.bytes_used) * 100 / fs.bytes), 1),
Round((SUM(fs.bytes) - df.bytes_free) * 100 / fs.bytes)
FROM dba_temp_files fs,
(SELECT tablespace_name,bytes_free,bytes_used
FROM v$temp_space_header
GROUP BY tablespace_name,bytes_free,bytes_used) df
WHERE fs.tablespace_name (+) = df.tablespace_name
GROUP BY df.tablespace_name,fs.bytes,df.bytes_free,df.bytes_used
ORDER BY 4 DESC;
Results are:

Alter user default tablespace and temporary tablespace

Hi guru,
target : to ensure that users don't have the SYSTEM tablespace as their TEMPORARY or DEFAULT tablespace
scenario :
user default tablespace temporary tablespace
xxyym system system
Question: How to alter user ?
tq

In a scenario, let's say you want to make USERS the default tablespace for existing users and TEMP the default temporary tablespace, you can also create the alter statements as below into one script based on the output and run it.
select 'ALTER USER '||username||' DEFAULT TABLESPACE USERS;' FROM DBA_USERS WHERE DEFAULT_TABLESPACE IN('SYSTEM')
and username not in('SYS','SYSTEM');
select 'ALTER USER '||username||' TEMPORARY TABLESPACE TEMP;' FROM DBA_USERS WHERE TEMPORARY_TABLESPACE IN('SYSTEM');As magnus mentioned, don't forget to do this(if USERS and TEMP is what you want to go with) :
ALTER DATABASE DEFAULT TABLESPACE USERS;
ALTER DATABASE DEFAULT TEMPORARY TABLESPACE TEMP;

Users tablespace physical IO

Hello,
I have a database set up with a separate disk volume for users.dbf.
I also create an additional tablespace in a different disk volume by
create tablespace test_users datafile '/opt/vxfs/temp10/test_users.dbf' size 128K autoextend on next 8K ;
"test_users" tablespace is dedicated for the test table. I run some queries on the test table.
As expected majority of the physical IO transactions are in the volume that holds the "test_users.dbf". But what confuses me is the few physical IO happening on "users.dbf" volume. Although the number of IO blocks transferred is less in users.dbf, compared to test_users.dbf, it is significantly high.
Note: No other table is queried that could be using users.dbf. Actually there is no other table that I created in the database.
system details : HPUX ,oracle11G
Any explanation for physical IO activity in users.dbf or some references would be great.
TIA,
Nanjappan

Seems like you are not factoring two caches into your equation.
There is an Oracle db buffer cache sitting between SQL + PL/SQL and the objects in the USERS tablespace.
There is a Unix file system cache sitting between Oracle accessing the physical datafile and the o/s kernel fs driver performing actual physical I/O on that file and that fs volume.

Error when dropping a user/tablespace

Hi
I am trying to drop user/tablespaces, but I got the following error
SQL> drop user SM92 cascade;

Currently this user has not tables or view, the statement select * from all_tables where owner='SM92' return no row
ANyone knows why I can't drop this user? What should I check?
Thanks

Hi, probably the user has dependency with other schemas, please review the Note:361576.1 into metalink site.
Good luck.
