Defragmentation of the tablespaces?
DB version: 11.2.0.4
Platform: Oracle Linux 6.5
3-node RAC DB
We have a TB 23 DB, and we met some performance issues lately. Sound mainly due to poorly written queries, large volume of data in the result set,... etc. But, this application was asked at a meeting if I could check that storage space (not tables) are fragmented. Apparently, in his old store DBA there did some 'Defragmenting' of tablespaces for the same application solve some performance problems.
To resize the data files, move to another tablespace DB objects so that the HWM in a particular data file is reset and then we could run the RESIZE command. But this isn't "defragmentation".
In the thread below, Justin cave explains that "a managed tablespace locally cannot effectively be fragmented."
That Justin is meant by that? Why have we not need "defragmentation" to locally managed Tablespaces?
Since I worked on 11g, I don't know the history. Done, DBA do a sort of defragmentation for older versions?
https://community.Oracle.com/thread/2508361
In general, you don't need to defragment of LMT because they re - operate segments more effectively. That assumes a particular definition of the fragmentation that don't understand what some people call "Gruyère" fragmentation, which means free space holes, spread across the tablespace. Sometimes it is wise to reclaim this space, generally do not, since generally the trend is to use space.
Many more details are in the link given Aman, but there are a few somewhat obscure situations where you would not automatically exclude the defragmentation:
A tablespace that has been migrated from DMT could have a few deferred maintenance on the lookout for defragmentation.
You might still have DMTs. You shouldn't, but there is nothing no longer this deferred maintenance upgrades of version (I do not forget something hope).
Some applications do stupid things like add and remove tables and if done in a strange order (as drop any other individual and adding more), can travel on limits of segment requirements (as Jonathan explains in some links on the moving objects until the beginning of storage spaces).
It is also possible to be unlucky and have performance issues based on the distribution of physical data get worse by moving data autour.
In general, Oracle did some good things, but be prepared to do an investigation of mind, when it is not. It allows to be confident and knowledgeable on the bases then. For the 'fragmentation' in particular, a Manager may well have been seduced by myths or the specific practices that don't apply generally. "Best practices" may suffer, too.

Hi all
I'm in the middle of a migration, and currently I am performing a VINE for this. The tablespace should I migrate is 3TO in size.
I've checked endian, its perfect, the two BONES are similar.
No violation not found for verification of transport, the tablespace is autonomous, I also did the expdp for the tablespace. After that, I copied all the 3 TB data files and emptying of the export to the destination server.
Now, here's where I'm confused. The next step is to create appropriate patterns.
The schema name and a source tablespace is CCF1 and the destination is CCF2 respectively.
I guess I'll have to create the CCF2 user on the destination server and to do so, first, I have to create tablespace CCF2 so that I can create the user and assign the default tablespace, that means I have to create the tablespace with 3 TB of data files value?
But what about the data files which I already copied during the source? I need 6 TB of space on the volume to accommodate the two data files. Please correct me if I am wrong somewhere... I'm sure I'm

You are so confused, because if you follow all steps in the Document Oracle you don't have to create storage spaces and users. If you have exported metadata with Data Pump EXPort, you must import the metadata to your target database.

Hello
I need to increase the size of the tablespaces in EBS R12 Database 11.2.0.3.0:
APPS_TS_TX_IDX
APPS_TS_SEED
APPS_TS_TX_DATA
But they all have multiple datafiles:
Example for APPS_TS_SEED:
[data oracle@ebs122dev] $ of the hs - a_ref0 *.
1, 5G a_ref01.dbf
1, 2G a_ref02.dbf
508M a_ref03.dbf
2, 0G a_ref04.dbf
2, 0G a_ref05.dbf
2, 0G a_ref06.dbf
Many of the datafiles should I resize to increase the size?
Thank you
Luis
Hello
It does not matter what file you resize.
Personally, I prefer to start with the first file and reach the largest file size and resize then the following.
In addition, having the files with a size that is a multiple of 1 GB is a good practice for me.
Another option is to activate the autoextend for data files option.
You can set the maximum size of 4 GB for example all files in storage areas that are growing rapidly.

ORA-01659: impossible to allocate MINEXTENTS beyond 2 in the tablespace test
Hello
I created a table and tried to insert records over 2 million and I'm getting an error such as ORA-01659: impossible to allocate MINEXTENTS beyond 2 in the tablespace test.
Used tablespace percentage is only 73%.
I used below when creating table

Please suggest me how to solve this problem.
Thank you

Hi @Suri
I see no problem in storage settings in your table.
But the number of rows helps you insert and in the free space in your tablespace.
Perhaps too much space is needed for your data and storage space can not support.
The only things you can do is the following:
(a) try PCT_INCREASE to 0, this product extensions to equal size.
(b) put the PCT_FREE less than the default of 10. But it is advisable if you make updates to your table.
(c) maybe create your table with the clause compress, just for bulk inserts, but this depends on the use of the table.
(d) ask your DBA to increase the data files of the TEST table space or add more data files.
(e) using the package DBMS_SPACE, you can calculate the space used by your table in tablespace TEST. g 10 and later versions.
See the following example:
SQL> SET SERVEROUTPUT ON SQL> DECLARE lc_tablespace VARCHAR2(100) DEFAULT 'CC_TBSD001_MOVI_DOMICILIOS'; lc_megabytes SIMPLE_INTEGER DEFAULT 1024*1024; lc_estimated_rows SIMPLE_INTEGER DEFAULT 45000000; lc_pct_used SIMPLE_INTEGER DEFAULT 10; l_cost_columns SYS.CREATE_TABLE_COST_COLUMNS; l_mbytes_to_be_used NUMBER; l_mbytes_to_be_allocated NUMBER; BEGIN l_cost_columns := SYS.CREATE_TABLE_COST_COLUMNS( SYS.CREATE_TABLE_COST_COLINFO('NUMBER' ,15) ,SYS.CREATE_TABLE_COST_COLINFO('NUMBER' ,10) ,SYS.CREATE_TABLE_COST_COLINFO('NUMBER' , 4) ,SYS.CREATE_TABLE_COST_COLINFO('VARCHAR2', 6) ,SYS.CREATE_TABLE_COST_COLINFO('VARCHAR2', 4) ,SYS.CREATE_TABLE_COST_COLINFO('NUMBER' , 1) ,SYS.CREATE_TABLE_COST_COLINFO('NUMBER' , 4) ); DBMS_SPACE.CREATE_TABLE_COST(lc_tablespace ,l_cost_columns ,lc_estimated_rows ,lc_pct_used ,l_mbytes_to_be_used ,l_mbytes_to_be_allocated ); l_mbytes_to_be_used := l_mbytes_to_be_used/lc_megabytes; l_mbytes_to_be_allocated := l_mbytes_to_be_allocated/lc_megabytes; DBMS_OUTPUT.PUT_LINE('Megabytes to be used: '||TO_CHAR(l_mbytes_to_be_used)); DBMS_OUTPUT.PUT_LINE('Megabytes to be allocated: '||TO_CHAR(l_mbytes_to_be_allocated)); END; /

Determine the space allocated to the tablespace on disk and the database free summer
Hello
Using oracle 11.2.0.3 and want to determine that some new storage space will be large enough to hold the data that we intend to move in them these is large enough.
When watching in Oracle enterprise manager see tablespaces but all look to have a default value 1024 MB and when run query below don't even see the tablespaces.
Another team created these and advised 4 GB but want to verify this.
How can we be sure that 4 GB was allotted to each of the tablespaces concerned before moving data.
Select df.tablespace_name "Tablespace"
totalusedspace 'Used MB',
(df.totalspace - tu.totalusedspace) "MB free.
DF. TotalSpace 'Total MB. "
round (100 * ((df.totalspace-tu.totalusedspace) / df.totalspace))
"PCT free."

collect statistics for the tablespace
Friends...
OS: Linux
DB: 11 GR 2
Data size: 1 TB
I spend monthly multiple partitioned table spaces and bring together in a single annual partition. (for example tbs_2014_01, tbs_2014_02 - tbs_2014_12... all combine them into tbs_2014 as a tablespace)
Over the weekend, work of database gets executed that collects statistics that are obsolete, it collects all the segments that have been moved from the storage.
Given that the collection of statistics at the end of the week takes too long, I tried to find a smart way to collect statistics after each tablespace move rather than waiting for job to weekend which will take two or three days to complete.
1. is there a way to gather statistics at the tablespace level and collect statistics for all objects in this table space?
2. how to determine the overall stats of collection of statistics part?
That is, suppose I have move the tbs_2014_01 tablespace and collect statistics with global stats that could take 2 hours but it will be difficult to spend 2 hours for each stats global tablespace which in my opinion is not good and we should be collecting global stats only once.
3. any other advice?

I've not been asked to collect statistics to the tablespace but level to collect statistics after that finish objects move in storage.
Given the size of the data, it is difficult to gather all the statistics at the weekend so trying to understand another method to collect the statistics the weekend load will be less.
You can collect statistics object on an object by object basis level after that each object has been moved.

I am facing error during the creation of tablespace that my system tablespace is full. Although the system tablespace is autoextend and there is space available on the hard disk what preventing the system tablespace not capable to autoextend. I checked and there is no space in the system tablespace.
I encountered a similar problem earlier for one of the could not tablespace autoextend even though autoextend is on and enough free space on hard disk (in a different environment)

What could be the reasons that although if autoextend is the tablespace not power autoextend.

Autoextend would also have a maximum limit of how much of the data file would be able to expand. So, what is the value of that? I don't see other reasons except that you made out of the maximum space allowed for the data file extend and which is prohibiting him from extends.

Diffrence between the tablespace is ONLINE and READ WRITE?
Hi all
I'm very confused on the tablespace is ONLINE and READ WRITE?
Some say that if the tablespace is online, this means that its READ WRITE and when its offline then its READ-only.
So, what is the difference between them:
ALTER TABLESPACE offline tablespacename; -> done mean READ only now?
ALTER TABLESPACE tablespacename online; -> is it means its READ WRITE now?
If Yes, then what is the use of the following command if above 2 commands? :
ALTER TABLESPACE tablespacename [READ ONLY |] READING WRITING];
Kind regards
Confused Ritu
In addition, when the tablespace is offline, objects belonging to those who are not available for use to users. You wouldn't be able to query for objects in a tablespace offline.
When the tablespace is read only - no write operation cannot be performed i.e. etc. INSERT/UPDATE/DEL. Oracle says that read-only tablespaces provides a way to protect the historical data so that users cannot modify it. You can drop objects, such as tables or indexes, to a tablespace read-only, but you can't create or modify objects in a tablespace read only
In order to bring a tablespace OFFLINE to ONLINE - so that it is available to users, you must "ALTER TABLESPACE online tablespacename" command. A tablespace online can be READ ONLY or READ WRITE mode.

How to move the tablespace SYSAUX ASM file system when the database is opened?
OS: RHEL 5.9 with UEK
Database version: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

- format of backup as copy tablespace SYSAUX "+ SYSTEM";
- tablespace SYSAUX switch copy;
But I want to know how I can move the ASM filesystem SYSAUX tablespace when the database is opened.
Thank you.
The two doc tells how to move sysaux when the database is opened:

When OMF add the data file in the tablespace
Hi friends,
We use oracle 11.2 with CMS (oracle managed file) for the database on the linux platform. the parameter - DB_CREATE_FILE_DEST had been set. at the present time, we received a message from global warming this tablespace criterion is 85% full.
According to the document of the oracle, OMF auto will add a data file in the tablespace tast. more than a week, I do not see any data file has been added by OMF.
I want to know when OMF adds the data file in the tablespace? 85% or 95% or some (parameter) setting this action?
Thank you
newdba
OMF does not automatically add a new data file. You must explicitly add a new data file with the ALTER TABLESPACE ADD DATAFILE command tbsname.
What is OMF is to provide a Unique name and a default size (100 MB) for the data file. That is why the ALTER TABLESPACE... Command ADD DATAFILE that you run didn't need to specify the file size or file name.
