Size of Tables & Tablespaces
Hi All,
I have one doubt regarding the size of tables & t/s , For Ex: last week my table(emp) size is 5g, after 7 days it was increased to 2g, how can i know last week size of Table & after 7 days size of Table,
Ple help me.....
What version of Oracle? I know that in 10g+ there is a table in the AWR that has tablespace size data but I am not sure about at the segment level. The problem is though you are not allowed to query the AWR tables without possessing an EM Diagnostic and/or Performance Pack license in addition to your regular Oracle license.
In all cases you can roll your own table size tracking process by copying dba_segments rows that have changed since the last check on a regular basis. You can use cron or dbms_scheduler to run a pl/sql routine to do the comparson saving the new sizing information.

Determine size of tables/tablespaces on disk using EM
Hi,
I now have access to 10g Enterprise Manager - newbie.
Usually use user-segments to find size of table/tablepace on disk.
Is there a way to do this uisng Enterprise Mnager?
ThanksFor tables:
Login->Schema->Tables->'Select Schema'->Go-> You will see all the tables -> Click on the table you want to see all the information.
For tablespaces:
Login->Server->Tablespaces->You will all the tabespaces.
Just Explore the EM, you will find everything. -
I don't know if this is a "valid" question. We have users running reports on our production system. The sometimes complain about the temp space being too small (due to their queries crashing when using too much temp space).
But I also have a feeling that you can keep throwing disks at TEMP space, and that it will never be enough.
What should the size of a database's TEMP space be - is there a rule of thumb for this ?
DirkThere are several considerations that you should take into account when you try to size your temporary tablespace:
First, how much sort does you average transaction need and how many concurrent transactions does your system need to support. This number gives you a starting point for the minimum workable size for normal operations.
Now, how big is the largest table on your system and do you wish to be able to support select * from biggest order by ? Supporting an unqualified select on your largest table may not be required.
How big is the largest index in your system? It is likely that you need to have enough temp space available to recreate this index in the event of corruption without having to take special action to allocate more space to temp on a temporary basis. But having to add space in the event of a diaster might be acceptable.
Figure out what the largest sort operation you need to be able to support is and then add enough space to handle the number of concurrent average transactions that would be expected to be on the system at the same time. This is the size you should use for your temporary tablespace.
It is better to have all the space you will need for any normal and for any maintenance operation available at all time rather than trying to find additional file space to support special maintenance tasks or diaster recovery operations.

How to know exact size of table with blob column
I have a table with one BLOB column. I ran this query.
select bytes/1024/1024 from user_segments where segment_name='GMSSP_REQUEST_TEMP_FILES'
(user_segments is a view)
it gave me 0.125
It means size of table is 0.125. I have uploaded 3 files to this table. Each of them is of 5 mb. After that I check size of table. but result was same. i.e 0.125.
Can any body tell me how to know exact amount of space consumed by files. I am expecting following result
size should be (5+5+5+0.125)MB
Any help is appreciated.
Thanks.

How can I change the size of table control in table maintenance re-gen?
Hello Experts,
I hv created a maintenance view and after generated table maintenance view for it.
now it adjusts the size of table control in table maintenance generation.
I want to change the size (width) of table control and again re-generate the table maintenance.
But when re-generation occurs, table control size is set to initial.
why it is happening? and wt to do to solve this issue? any user exit?
I need the changed size of table control even if its re-generated.
Regards,
R.HanksHello Ronny,
Goto SM30, Enter your table name for which you have maintained your table maintainence generator .
When the maintainence screen appears for your table name , Goto System->Status->Screen Program name.
Copy that program name from there.
Open that module program through SE80,this is the program name of your SM30 screen which appears when we enter our table name in SM30 transaction.
In SE80,click the layout of the module program name you have entered there.
Its layout will display you the table control(of SM30) present to enter your your enteries.
In the change mode you can change its size , savee it and activate that program.
Now goto to SM30 again and enter your table name, it will show you the changed size of the table control used to take the enteries.
Note:This changed size is only for your table name and it will remain of its previous size for other table enteries.
Hope it helps you.
Thanks Mansi -
How to fix the size of table data in html
I want to fix the size of table data in html. ie if i want to insert only 50 char in a <td> field then it contain only 50 character, after that it switched to another line and contain the remaining character. Means <td> field wil not get automatically adjust there size according to data.
you cant specify how many characters a td cell can have but u can specify the pixel width of a td cell
<td width=50>
as long as you have wrap text on, then text will not force the box size over the 50 pixels
this wont limit it to only 50 chars though, you will probably have to use some javascript to cut the string down to size (unless youre using something like php or asp then that will do the trick too) -
SQL*LOADER(8I) VARIABLE SIZE FIELD를 여러 TABLE에 LOAD하기 (FILLER)
제품 : ORACLE SERVER

SQL*LOADER(8I) VARIABLE SIZE FIELD를 여러 TABLE에 LOAD하기 (FILLER)
==================================================================
PURPOSE
SQL*LOADER 에서 variable length record와 variable size field를 가진 data
file 을 여러 table에 load하는 방법을 소개하고자 한다.
( 8i new feature인 FILLER 절 사용)
Explanation
SQL*LOADER SYNTAX
여러 table에 load하고자 할때에는 control file에 아래와 같이 하면 된다.
INTO TABLE emp
INTO TABLE emp1
fixed length field을 가진 data file을 여러 table에 같은 data을 load하고자
한다면 아래와 같다.
INTO TABLE emp
(empno POSITION(1:4) INTEGER EXTERNAL,
INTO TABLE emp1
(empno POSITION(1:4) INTEGER EXTERNAL,
위와 같이 양쪽 table의 empno field에 각각의 load할 data로부터 1-4까지를
load 할수 있다. 그러나 field의 길이가 가변적이라면 위와 같이 POSITION 절을
각 field에 사용할 수 없다.
Example
예제 1>
create table one (
field_1 varchar2(20),
field_2 varchar2(20),
empno varchar(10) );
create table two (
field_3 varchar2(20),
empno varchar(10) );
load할 record가 comma로 나누어지며 길이가 가변적이라고 가정하자.
<< data.txt >> - load할 data file
"this is field 1","this is field 2",12345678,"this is field 4"
<< test.ctl >> - control file
load data infile 'data.txt'
discardfile 'discard.txt'
into table one
replace
fields terminated by ","
optionally enclosed by '"' (
field_1,
field_2,
empno )
into table two
replace
fields terminated by ","
optionally enclosed by '"' (
field_3,
dummy1 filler position(1),
dummy2 filler,
empno )
dummy1 field는 filler로 선언되었다. filler로 선언하면 table에 load하지 않는다.
two라는 table에는 dummy1이라는 field는 없으며 position(1)은 current record의
처음부터 시작해서 첫번째 field을 dummy1 filler item에 load한다는 것을 말한다.
그리고 두번째 field을 dummy2 filler item에 load한다. 세번째 field인, one이라는
table에 load되었던 employee number는 two라는 table에도 load되는 것이다,
<< 실행 >>

To shrink the size of TEMP tablespace
Dear all,
There is a databse with RAC, now in OEM the size of TEMP tablespace has been reached at 99.9%. now we want to shrink the size of TEMP tablespace.
how to we do that???????
plz help me...........Temporary tablespaces usually show they are full, however this space is not actually in use. It is rather allocated. Oracle has evaluated the best way to obtain the most of performance, and he said it is better to allocate once than allocate-deallocate-reallocate extents, so temporary space is not 'released'.
If you want to feel psychologically more confortable with lower allocated space, you can drop your tablespace (create an interim default temporary tablespace first) and recreate it.
You can also rebuild temporary datafiles:
alter tablespace temp add tempfile 'C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP01.dbf' size 32m;
SQL> select name from v$tempfile;
NAME
C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP.DBF
C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP01.DBF
SQL> alter database tempfile 'C:\ORACLE\ORACLEXE\ORADATA\XE\TEMP01.DBF' drop including datafiles;
Database altered. -
Setting the size of a tablespace prior to its creation
Hi guys,
Oracle version: 10.2.0.x
OS: Windows 32bit
I was wondering if there are any 'conditions' in setting the intial size of a tablespace prior to its creation. This is because, one of our customers wants to export and import from one schema into another but set an initial size for a tablespace during its creation and prior to importing data into it, but we have a database wizard tool that creates the accounts/schemas by using the following underlying sql:-
CRETE TABLESPACE <tbl_name> datafile <path><datafile_name>.dbf SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 32000M DEFAULT STORAGE (INITIAL 256 NEXT 256K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCREASE 0) ONLINE;
Under normal circumstances, what he would do is to use our wizard tool and create an account and then import data from an export dump.
But he wants to create a tablespace using a SQL something like:-
CRETE TABLESPACE <tbl_name> datafile <path><datafile_name>.dbf SIZE 2000M AUTOEXTEND ON NEXT 500M MAXSIZE 32000M DEFAULT STORAGE (INITIAL 256 NEXT 256K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCREASE 0) ONLINE;
He thinks this should be ok because his export dump would be on size 2GB and would want to import all of that 'at once' i.e. without actually using autoextend feature for the first 2GB.
Does this make any sense? Do you guys see any difference 'performance-wise' between the 2 create tablespace statements?
I think the second sql (with size 2000M initially) seems to be a more logical approach but I am not really sure of the implications going down the line performance-wise.
Any help/input much appreciated!
Thanks guys1) Provide the facility in your tool to change the default size of datafiles and keep autoextend off.You won't believe it...we had this option in a previous version but now it isn't there anymore!
But why turning off AUTOEXTEND? I mean, our customers are not meant to modify anything in the database other than via using our software, hence we would want our customers to just use the software as it is but have their DBAs monitor the growth of any datafiles etc...
2) Let your tool do what it is doing and then manually increasing the size of the datafiles and making autoextend off once you have created the tablespace and before doing import. This can be done by your tool or loggin to the database.We could do this, but we don't want our customers to manually finger the database as they are/might not be Oracle-efficient and wouldn't want production systems to crash for the same reason.
Hence we could just give them the SQL to be replaced with the 'default' one and then create a tablespace via the tool which would create a tablespace with an initial size of 2GB+ and with greater autoextend facility (such as autoextend on 500M) rather than 100M so that there are fewer autoextends.
Also, in your point 2, are you saying to turn off autoextend only for the import and set it back on by alter tablespace....?
Thank you. -
Problem in DBcopy with size of table SWW_WI2OBJ
We are facing performance problems because of the large size of table SWW_WI2OBJ there are 5.4 million records in the table.
The growth was probably caused by faulty generated workflows on object RMPSCASE.
Does anyone know what is a normal size of table SWW_WI2OBJ
And how can i archive this table? or delete records without effect on the correct wf id's.
Are there tools for these actions and where can i find them?
Kind regards,
Reinhard SportelHi Reinhard,
The normal size of table SWW_WI2OBJ is depending on how many workflows you have running in your system, on how complex they are, and on how intensively they are used. To get an idea you should not get more than two or three times more entries in SWW_WI2OBJ than in SWWWIHEAD (more than that would be an indication of wrong workflow design).
To solve your problems there are tools to delete workitems from DB, but they should not be used in a production environment (unless you are really 100% sure of what you are doing, but there is no coming back possible)
I would suggest you investigate the workitem archiving functionalities to archive your faulty workflows (tx SWW_SARA). There is plenty of information available about this in the SAP help.
Cheers,

Oracle 11.1.7.0
We have partitioned, non-partitioned indexes.
1. Is there a way to find index size per table. As break down by table and index name how much each index is taking and where space is being used.
2. Also, Is there a way to find free space within an allocated index?
Edited by: user628400 on Nov 26, 2009 12:13 PMHello,
To collect statistics about indexes you must VALIDATE it first then put the datas
into a Table.
So this is the way I use:
1. Create a Table to collect the datas:
create table my_index_stats (
index_name varchar2(30),
height number(8),
del_lf_rows number(8),
distinct_keys number(8),
rows_per_key number(10,2),
blks_gets_per_access number(10,2),
btree_space number(12,0),
used_space number(12,0),
pct_used number(12,0)
/2. Validate the Index
validate index "<schema>"."<index_name>";3. Collect the datas
insert into my_index_stats
select NAME, HEIGHT, DEL_LF_ROWS, DISTINCT_KEYS, ROWS_PER_KEY,
BLKS_GETS_PER_ACCESS, BTREE_SPACE, USED_SPACE, PCT_USED
from INDEX_STATS;
commit;Then, you query the Table MY_INDEX_STATS and the USED_SPACE gives you an idea (in Bytes) of the space used inside the index.
The BTREE_SPACE gives you the size of the Index.
So from BTREE_SPACE and USED_SPACE you can know the wastage space of your Index.
Hope it can help,
Best regards

Hi All ,
I try to create a temporary tablespace
1 create temporary tablespace test1
2 tempfile 'F:\datafile\test1.bdf'
3* size 500k
4 /
create temporary tablespace test1
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required
How would we calculate the minimum size required to create a temporary tablespace ?Hi,
You can test it by providing different sizes.
1 create temporary tablespace test1
2 tempfile 'F:\datafile\test1.bdf'
3* size 1024k
4 /
create temporary tablespace test1
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required.
1 create temporary tablespace test1
2 tempfile 'F:\datafile\test1.bdf'
3* size 1050k
4 /
Tablespace created.
So that means file size should be greater than 1024K.
