Temporary tablespaces in Oracle 10g

Hi,
I have created temporary tablespaces in Oracle 10g from the SQL prompt,but when i list the corresponding datafiles from v$datafile there tempfiles are not listed there,why is it so?

What is the use of SYSAUX Tablespace in Oracle 10G

Dear Experts,
Please Tell me What is the use of SYSAUX Tablespace in Oracle 10G Because
during Web Load Testing It is going to increase countinuosly.Although i am not using this with any tables.
How Can I find out the what is gong on in this.
Can I Remove this tablesspace and other non using Schemas like FLOWS_020100,MDSYS,OUTLN,DIP and TSMSYS etc.

What is SYSAUX?
The SYSAUX tablespace provides storage of non-sys-related tables and indexes that traditionally were placed in the SYSTEM tablespace. For example, the tables and indexes that were previously owned by the system user can now be specified for a SYSAUX tablespace. Unfortunately, Oracle still places the SCOTT schema and the other demonstration schemas in the SYSTEM tablespace. Go figure.
The SYSAUX tablespace is specified with the CREATE DATABASE command. This is demonstrated in the example database creation script in Figure 1.1.
CREATE DATABASE test
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 3
MAXDATAFILES 100

Oracle10g sysaux
With the new SYSAUX tablespace, Oracle comes closer to providing all the needed tablespaces for a truly OFA-compliant database right out of the box. With just one CREATE DATABASE command we can specify the SYSTEM tablespace, the TEMPORARY tablespace, the AUXSYS tablespace, the default UNDO tablespace, and the redo logs.
Of course, with the Oracle Managed Files option you can create an entire database with a single command, but the database created is not suitable for production use and is not OFA-compliant.
The SYSAUX tablespace is required in all new 10g databases. Only the SYSAUX tablespace datafile location is specified. Oracle specifies the remainder of the tablespace properties including:
online
permanent
read write
extent managment local
segment space management auto
If a datafile is specified for the SYSTEM tablespace, then one must be specified for the SYSAUX tablespace as well. If one is not specified, then the CREATE DATABASE command will fail. The only exception is for an Oracle Managed File system.
During any update of a database to Oracle Database 10g, a SYSAUX tablespace must be created or the upgrade will fail. The SYSAUX tablespace has the same security profile as the SYSTEM tablespace. However, loss of the SYSAUX tablespace will not result in a database crash, only the functional loss of the schemas it contains.
Can I drop SysAux?

Can I import a tablespace into Oracle 10g Express Edition

I am very new to Oracle 10g Express Edition. We have a server running Oracle Enterprise Edition and we have been creating a transportable tablespace to be imported into a few servers. This works fine for us. I would like to find out if I can import the tablespace into Oracle 10g Express Edition. Someone told me that I should be able to do that but I have no clue to how to do it. If this is possible, can someone tell where to find the information how to do this.
Thanks,
RJ

I finally tried it and I got the following errors:
IMP-00017: following statement failed with ORACLE error 721:
"BEGIN sys.dbms_plugts.checkCompType('COMPATSG','10.2.0.2.0'); END;"
IMP-00003: ORACLE error 721 encountered
ORA-00721: changes by release 10.2.0.2.0 cannot be used by release 10.2.0.1.0
ORA-06512: at "SYS.DBMS_PLUGTS", line 2004
ORA-06512: at line 1
IMP-00000: Import terminated unsuccessfully
Am I right that the server that I exported the tablespace is using Oracle 10.2.0.2.0 while Oracle Express is 10.2.0.1.0? I looked around and I did not see Oracle Express version 10.2.0.2.0 that I can download. Is there a patch or something to upgrade it?
Thanks,

Temporary tablespace in oracle 8i

hi,
i am working in oracle 8.1.7.4.0.i am creating a temporary tablespace.
After creating the temp tablespace i am going to assign it as default temporary tablespace.
alter database default temporary tablespace <tbs-name>;
but its showing error...as
ora-02231 - missing or invalid option to alter database,
how to assign the default temporary tablespace in this oracle version.
Rgds...

You can not set the temporary tablespace at the database level as default temporary tablespace in Oracle 8i. From Oracle 9i onwards, you can create and assign the temporary tablespace at the database level.
Only possible way in Oracle 8i is at the user level.
i.e.
SQL> alter user scott default tablespace TEMP;
HTH.

Create tablespace in Oracle 10g Express

Hi,
I've been playing around over the last few days with Oracle 10g Express and I need to create my own tablespace and therefore create user associated with my custom table space.
I tried with the command create tablespace, but I am not successful with configuring the parameters such as the datafile location and such. I did go through the Oracle Concepts Guide which was very helpful, but I must be missing something.
Also assuming that my db scheme will be part of my application and therefore released to my client as script so they can re-create my database how would the table space integration work on their end.
I would I have to place my first line of the script to create the table space and ask them for database file location?
Any advice will be appreciated.
Thank you in advance.

The reason why I think I should create my own tablespace is because I am creating a database scheme and thus I think it is appropriate to place my db scheme in its own tablespace instead of simply using the Users tablespace default.

Thank you.How about checking with the fine SQL Reference manual for the syntax of the CREATE TABLESPACE command?
Learning where to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com. Drill down to your product and version.
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.

Problem with global temporary table in Oracle 10g

Hi All,
I face a peculiar problem in Oracle 10g with respect to Global temporary table.
Have Oracle 10g version in Production and 11g version in UAT.
Table_
create global temporary table TT_TEMPGPSMANUAL
Col_1    VARCHAR2(50),
Col_2    VARCHAR2(500),
Col_3    VARCHAR2(50),
Col_4    VARCHAR2(50),
Col_5    VARCHAR2(15),
Col_6    VARCHAR2(20),
Col_7    VARCHAR2(250),
Col_8    VARCHAR2(20),
Col_9    VARCHAR2(15),
Col_10   VARCHAR2(20),
Flag     NUMBER,
Col_11   INTEGER,
Col_12   VARCHAR2(50)
on commit preserve rows;So this should preserve the rows inserted into this table until the session ends.
Have a webpage in front-end where in turn, it opens another page (session is carried through) and a few rows will be inserted to this table from the webpage (through a function) on submit and the current page will be closed.
From the parent page, if I open the sub-page data inserted in the temporary table are held and displayed (another function to fetch the values in the Global Temp table).
The Problem in Oracle 10g (Production) is, this is not happening properly. When I close and open the sub-page, not every time I get the data stored i.e if I close and open the page 10 times, atelast 4 times the data is missed in the page (I am not getting values from temp table) randomly.
But this does not happen in UAT (which has Oracle 11g installed) as I get the data in the webpage consistently. After passing UAT, when we rolled out to Prod, getting this issue which we are unable to get what could be the reason.
It is very hard to debug using GTT dynamically in prod. It takes time to get Oracle 11g installed in Prod.
Can anyone suggest?
Regards
Deep

Also, I am opening the sub-page from the parent page (through a hyperlink). Then in this case, Would session will be changed from parent to subpage? (I am not aware exactly and have the impression that, as the second page is a child, I guess it would take the same session).I'm not sure what "sub-page" or "parent page" means to you. If you're just linking from one page to another, "parent" and "child" don't really make sense since page A links to page B and B links to A quite frequently.
Assuming that you have to log in to access the site, it is likely that the two pages share the same middle tier application session. It is unlikely that the middle tier would hold the database session from the first request open waiting to see if the user eventually requested the second page. It is theoretically possible that you could code your middle tier this way but it is extremely unlikely that you would want to do so for a variety of reasons. So, when you say "would [the] session ... be changed", it is likely that the application session would be the same for both calls but that the database session would be different.

Shrinking BLOB tablespace in Oracle 10g

Hello,
I have table created with 32 GB in Oracle 10g with BLOB field containing images. after that I have deleted some of the images from the table but when I'm checking free space, it is show full 32 GB. But when I'm looking at Toad it shows me out of 32 GB 17 GB is free.
my question is how to shrink/resize blob tablespace/table having BLOB field in oracle 10g 2rel ?

Hello urgent,
Tablespace management is not really an Oracle Spatial topic, I suppose these are georaster images?. You probably want to search and post in the more general database forums.
The quick answer is that it is not easy. Oracle tablespaces may only be "shrunk" if the free space is at the end of the datafile at the "high water" mark. If by some wild coincidence the images you removed were indeed at the back of the datafile, then you could alter the datafile with a RESIZE command. But the odds of that being the case are incredibly low. If you really, really MUST recover that space then about the only thing to do is export the data, delete it from the tablespace, shrink the tablespace and then import the data back in. Another approach if you have the space is just move the data into another empty tablespace and then drop the original tablespace. I would guess that the salary expended for you to take everything offline and do this would be more than just buying another cheap disk. Considering that in doing your daily work you may well indeed be in this position again in a few weeks, then it makes even less sense.
Now having said all that I have been in the situation where I MUST recover that space without taking everything offline.
One thing you can try is to "pop" the last items off the datafile (moving them to another tablespace) identified using the query below. But this is an exercise in futility unless your resources happen to be nicely "chunked" together near the highwater mark. Oracle tends to stripe resources across the available space in the datafile. So you might find you need to move half the contents before recovering any significant amount of space.
Cheers,
Paul

Resizing temporary tablespace in oracle 8i

Please,
I some questions on oracle 8i.
1. how do I know on oracle 8i if the tablespace X is the temporary tablespace?
2. I have someone that increase the size of the temporary tablespace, so I have to decrease it to its normal size, my question is when I do the following command.
alter database tempfile '/u02/oradata/TESTDB/temp01.dbf' resize 250M;
alter database tempfile '/u02/oradata/TESTDB/temp01.dbf' resize 250M
ERROR at line 1:
ORA-03297: file contains used data beyond requested RESIZE value
Does someone show me how to solve this issue?
Thanks

you can use the below sqls
sql>SELECT tablespace_name, extent_size, total_extents, used_extents,
free_extents, max_used_size FROM v$sort_segment;
From the output of the v$sort_segment query:
extent_size      : size of one extent, in number of Oracle blocks
total_extents     : total number of extents in the segment (free or in use)
used_extents      : total number of extents currently in use
free_extents      : total number of extents currently marked as free
max_used_size: maximum number of extents ever needed by an operation (like a sort):
sql> SELECT s.username, u.tablespace, u.contents, u.extents, u.blocks FROM v$session s,
v$sort_usage u WHERE s.saddr=u.session_addr;

Is it possible to rename dictionary managed tablespace in oracle 10g?

Hi,
Assume my system tablespace is dictionary managed in oracle 10g and one of my permanent tablespace is dictionary managed.
Pls let me know that permanent dictionary managed tablespace can be renamed or not using rename tablespace command or only locally managed tablespaces can be renamed?
thanks,
DB

Hi Guys,
thanks for the replies.
As suggested, i created a database with dictionary managed system tablespace and users tablespace .
I was able to rename users tablespace to users_test.
Eventhough dictionary managed tablespace is deprecated in oracle 10g, it will be better if they just add a line in the 10gR2 documentation under renaming tablespaces section that dictionary managed tablespaces also can be renamed.

How to define tablespaces in Oracle 10g and how put tables on tablespaces

Hello,
I'm having trouble to define the structure of tablespaces and how to distribute the tables/indexes/lobs on these tablespaces.
Do you know some rules on how to define this?
What I have until now:
1) Put table indexes in separate tablespace
2) Put lobs in separate tablespace and use storage clause when defining the lob column. Not sure how many tablespaces to use, I have tables with millions of lobs and tables with just one lob (with row containing the lob).
3) Please fill more rules here ...
Thank you, Alex.

Long story: I received database and schema creation scripts defined in Oracle 9i. I want to redesign the tablespaces number/storage and also to change the distribution of tables into tablespaces.
As an example I will show how tablespaces are created now. There is one tablespace for indexes BLUE_AUTO_INDX and one for each EXTENT MANAGEMENT of:
- 64K for BLOB , name BLUE_K064_BLOB
- 64K for tables , name K064_NTAB
- 128K for tables, name BLUE_K128_NTAB
- 512K for CLOB , name BLUE_K512_CLOB
- 4M for BLOB , name BLUE_M004_BLOB
- 64M for CLOB , name BLUE_M064_CLOB
- 8M for tables , name BLUE_M008_NTAB
- 1M for tables , name BLUE_M001_NTAB
- 256M for tables, name BLUE_M256_NTAB
Definition of each tablespace is like:
CREATE TABLESPACE BLUE_AUTO_INDX DATAFILE 'BLUE_AUTO_INDX01.DBF' SIZE 200M REUSE AUTOEXTEND ON NEXT 100M MAXSIZE UNLIMITED LOGGING ONLINE PERMANENT EXTENT MANAGEMENT LOCAL UNIFORM SIZE 64M SEGMENT SPACE MANAGEMENT AUTO;

Does this structure of tablespaces ok? I mean if the logic of one tablespace for different EXTENT SIZEs looks ok?

Temporary tablespace/OS-Oracle DB/Redo change vector

At minimum, this tablespace should be as large as the
largest index that will be created, plus 10% for
overhead. Can anyone please throw more light on this . Why is this .Is this a hard and fast rule and left to the discretion of the DBA?
This is just a general question.How big of an impact can an operating system have on an oracle database . I mean with respect to everything . Performance/security etc. Unix vs Windows . I do know that on a Unix based system it will be more better to have oracle installed. But isn't there anything that can be done to have the same efffect in every aspect oracle for an database on a windows machine ?
Responses are appreciated!
A redo record consists of
1.redo record header
2.one or more change vectors
What is this change vector.This vwent over my head.Can anyone please elaborate on this.

Within the limits of the Windows operating system, sure.
Realistically, most organizations use Unix for their large databases because
- when they made the decision about what operating system to use a decade (or more) ago, Windows was nowhere near enterprise ready
- given the human capital they have invested in Unix, there would be no point to moving to Windows
- there are many fewer high-quality Windows admins and Oracle DBAs with substantial Windows skills than Unix admins and Oracle DBAs with Unix experience
There is plenty that can be done to run a large Oracle database on a Windows machine successfully. Unfortunately, doing all these things tends to be harder on Windows, finding people knowledgable enough to do them properly tends to be hard, and relatively few organizations are invested enough in Windows to bother. That's changing over time, though-- there are a lot more Oracle databases on Windows today than there were 5 years ago.

10G: TEMPORARY TABLESPACES GROUP

제품 : ORACLE SERVER
작성날짜 : 2004-05-25
10G: TEMPORARY TABLESPACES GROUP
==================================
PURPOSE
이 문서에서는 10g New Feature 인 Temporary tablespace 의 group 에 대해 알아 보도록 한다.
Explanation
10g 에서는 temporary tablespaces 에 대해 group 을 지정하여 생성할 수 있고
consumer group 을 지정하여 resource manager 와 함께 적용하여 사용이 가능하다.
다음은 Temporary tablespace group 지정을 위한 기본적이 사항이다.
1. 하나의 temporary tablespace group 은 적어도 하나의 tablespace 가 존재해야 하고
maximum number tablespace 에 대한 limit 은 정해져 있지 않다.
2. Ttemporary tablespace 와 group name 을 동일하게 지정할 수 없다.
3. Temporary tablespace group 은
     1) 한 group 에서 다른 group 으로 move 가 가능하고
     2) Group 내에서 삭제 될 수 있으며
     3) 추가적으로 add 가 가능하다.
4. Temporary tablespace group 사용으로 인해
     1) Sort 결과를 유지하여 space 낭비를 막을 수 있고
     2) 동시에 여러개의 session connect 시에도 서로 다른 temporary tablespaces 를 사용함으로써
     temporary tablespaces 의 사용을 분산 시킬 수 있다.
     3) Parallel operation 시에도 multiple temporary tablespaces 사용이 가능하다.
Example
1. GROUP1 을 지정하고 GROUP1 에 속하는 temporary tablespace LMTEMP 1 를 생성한다.
이 때 GROUP 1 을 따로 생성할 필요 없고 temporary tablespace 생성시에 지정하도록 한다.
SQL> create temporary tablespace LMTEMP 1
tempfile 'D:\ORACLE10\ORCL\temp1_01.dbf' size 50M
tablespace group GROUP1;
SQL> select * from dba_tablespace_groups;
GROUP_NAME TABLESPACE_NAME
GROUP1 LMTEMP1
2. LMTEMP2 를 GROUP1 에 새로 추가한다.
SQL> create temporary tablespace lmtemp2
tempfile 'D:\ORACLE10\ORCL\temp1_02.dbf' size 2M
tablespace group group1;
Tablespace created.
SQL> select * from dba_tablespace_groups;
GROUP_NAME TABLESPACE_NAME
GROUP1 LMTEMP1
GROUP1 LMTEMP2
3. 기존에 존재하는 LMTEMP1 를 GROUP2 로 move 한다.
SQL> alter tablespace LMTEMP1 tablespace group GROUP2 ;
Tablespace altered.
SQL> select * from dba_tablespace_groups;
GROUP_NAME TABLESPACE_NAME
GROUP2 LMTEMP1
GROUP1 LMTEMP2
4. LMTEMP1 이 속해 있던 GROUP2 에서 LMTEMP1 를 제외 시키고 다시 포함시킬 수 있다.
SQL> alter tablespace LMTEMP1 tablespace group '';
Tablespace altered.
SQL> select * from dba_tablespace_groups;
GROUP_NAME TABLESPACE_NAME
GROUP1 LMTEMP2
SQL> select tablespace_name from dba_tablespaces where contents='TEMPORARY';
TABLESPACE_NAME
TEMP
LMTEMP1
LMTEMP2
SQL> alter tablespace LMTEMP1 tablespace group GROUP1;
Tablespace altered.
5. Temporary tablespace 와 group name 을 동일하게 지정할 경우 ORA-10918 에러가 발생한다.
즉, temporary tablespace 와 group name 을 동일하게 지정이 불가능하다.
SQL> create temporary tablespace lmtemp5
tempfile 'D:\ORACLE10\ORCL\temp1_05.dbf' size 50M
tablespace group lmtemp5;
create temporary tablespace lmtemp5
ERROR at line 1:
ORA-10918: TABLESPACE GROUP name cannot be the same as tablespace name
6. 존재하던 모든 temporary tablespaces 를 drop 하게 되면 group 은 자동으로 remove 된다.
SQL> create temporary tablespace LMTEMP3
tempfile 'D:\ORACLE10\ORCL\temp1_03.dbf' size 2M
tablespace group GROUP2;
Tablespace created.
SQL> create temporary tablespace LMTEMP4
tempfile 'D:\ORACLE10\ORCL\temp1_04.dbf' size 2M

Oracle 10g as Resource in IDM 5.5

Hi,
We started adding Oracel 10g Databases to our IDM-Resources.
When provisioning users into Oracle 10g Resource we get the following Exception:
com.waveset.util.WavesetException:
Error trying to update Oracle user 'G2814' ORA-30041:
Cannot grant quota on the tablespace
java.sql.SQLException: ORA-30041:
Cannot grant quota on the tablespace Since we already removed the oracleTempTSQuota-Attribute I assume that the adapter overwrites null values internally.
Any hints how to solve this problem?
Thanks in advance...
Oracle-Docs:ORA-30041: Cannot grant quota on the tablespace
Cause: User tried to grant quota on an undo or temporary tablespaceIDM_Technical_Reference_2005Q3M1 refernces Oracle 10g as supported resource

There is no need to give quota on temporary tablespace, because you will never create objects on a temporary tablespace
It is a wrong assumption to think that your temporary space usage will be limited by a quota.
The fact that you can "grant" quota on a temporary tablespace is rather a bug, which is fixed in 10gR2
Re: Cannot grant quota on tablespace
This bug is not fixed in IDM 6.0 SP1.

Temporary tablespace size

Hi,
I have a doubt regarding temporary tablespace. Oracle 9.2.0.5
When I create the default tablespace temp I see it growing and growing during some days until it reaches the maximum size and then it give the error ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
but monitoring the v$sort_segment I see one or 2 users logged and using the temp.
So my doubt is: what I have to do to find the BEST size for my temp tablespace. which queries is the recomended one to see the temp segments being used ?
Thank you

See http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96521/tspaces.htm#9566
To improve the concurrence of multiple sort operations, reduce their overhead, or avoid Oracle space management operations altogether, create temporary tablespaces. A temporary tablespace can be shared by multiple users and can be assigned to users with the CREATE USER statement when you create users in the database.
Within a temporary tablespace, all sort operations for a given instance and tablespace share a single sort segment. Sort segments exist for every instance that performs sort operations within a given tablespace. The sort segment is created by the first statement that uses a temporary tablespace for sorting, after startup, and is released only at shutdown. An extent cannot be shared by multiple transactions.
You can view the allocation and deallocation of space in a temporary tablespace sort segment using the V$SORT_SEGMENT view. The V$TEMPSEG_USAGE view identifies the current sort users in those segments.
