Size of tables
Hello,
I am new to oracle. I need to find the size of all the tables in a schema. How can I go about doing that? I can do it thru TOAD but that will take me a long time. Any1 have an idea or maybe even a script I can use?
Thanks in advance
OK that works!! Is there another way I can do it if I am logged in as sys or system but I wanna see another schema's tables?
Thanks for the all your help

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
작성날짜 : 2004-10-29
==================================================================
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 >>
$sqlldr scott/tiger control=test.ctl data=data.txt log=test.log bindsize=300000
$sqlplus scott/tiger
SQL> select * from one;
FIELD_1 FIELD_2 EMPNO
this is field 1 this is field 2 12345678
SQL> select * from two;
FIELD_3 EMPNO
this is field 4 12345678
예제 2>
create table testA (c1 number, c2 varchar2(10), c3 varchar2(10));

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

How to re-size the table in a OBIEE Report
Hi All,
I am creating a report with table and graph placing side-by-side. My graph size is big and table displaying only top 10 values. How can i increase the size of table to make it almost similar in size to graph. I tried various options like editing table and setting custom width and height, but did not work ??Hi,
you can increase the table size by using the table properties.
table properties-->Additional formatting options--->give the values of height and width like 800,600 etc.
mark if helpful/correct...
thanks,

How to disable right click option re-size on table column header?
Hi All,
Please let us know how to disable right click option re-size on table column header.
The issue is that when I right click on the column header, the column is selected and the context menu with options like Sort, Columns, Resize Columns, etc.. is popping. we want to disable column re-size option.
We are binding the table values programatically (not using Bc4J) and the Jdeveloper version is 11.1.2.2
Thanks in advance,
- Vignesh S.Hi Gawish,
Thanks for the reply.
This will make the particular column frozen and only work for that particular column.
My use case is that to remove the resize columns option from the context menu or to disable the right click option.
Making column selection as none will disable the right click option but we need column selection for sorting.
Is there any other way to achieve this?
Thanks in advance,

Estimated size of tables for DMU scan
The DMU estimates the size of tables, and uses this to determine how to parallelise the scans. I have a problem where the estimates are low, meaing that big tables (by bytes in dba_segments) are not parallelised and the scan takes longer than I think is necessary.
Some of the table have inaccurate statistics, but I can determine any correlation between anything in dba_tables (blocks?) and the size shown in the DMU.
I would like to know if I could help this my setting something using DBMS_STATS.SET_TABLE_STATS, or anyother method.
Thanks,
BenApologies again for not being clear I thought DMU was a well know abbreviation for Database Migration Assistant for Unicode and would be known on this forum. I've been so involved with it I may have been unclear with my terms.
I am running the Scan Wizard in the Database Migration Assistant for Unicode v1.1 (DMU). After I've completed the Object Selection, the Scan Details http://docs.oracle.com/cd/E26101_01/doc/doc.11/e26097/ch4scenarios.htm#BACEFAIG shows a list of table with a table size. The DMU then decides to split the scan of each table, based on some function of the table size. I would like to know where this Table Size is calculated from. It is not from dba_segments, as I have a table that is 7GB in DBA segments, that is showing as 0B in the Table Size column. The option to split can be deselected where the DMU has chosen to split the scan into chunks, but not selected where it has not.
If the Table Size is calculated from the table statistics then I would like to know if it is possible to set this via dbms_stats.set_table_stats, to improve the performance of the scans.

How to find out size of tables
Can you please suggest me how to find out the size of tables?
I need to find what would be the appropriate size required for rollback segment.
Your quick help would be highly appreciated.Sizing the Rollback Segments (rollback segment) is an iterative process and requires several scheduled maintenance windows to re-size the rollback segment, based on the DML load. The optimal rollback segment size is a function of system update load (as determined by v$rollstat and v$transaction):
a) The COMMIT frequency.
b) The size of RAM log buffers.
c) Specific Oracle parameters (log_buffer, db_writer_processes, log_checkpoint_interval).
d) The size of the rollback segment data files.
The total size of the UNDO area for a specific transaction is as follows:
If the undo is 'x' bytes for 'n' number of rows then
T = x * (N / n) * 1.05
Where T = Approximate Total undo for the transaction in bytes.
x = Undo for the individual transaction.
N = Total number of rows in the original table.
n = Total number of rows in the test table.
Optimal rollback segment sizing is an iterative process, and is normally "tuned" over a period of several weeks. Generally, we build spreadsheets to track usage and determine the optimal size: -
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.
