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: -

How to find out when a table was last updated?
Is there a way to find out when a table was last updated/inserted/deleted? Thanks!
There may be an easier way but if you are trying to get info on something that has already happened look at your redo logs and archived logs. It would be hard but in V$LOGMNR_CONTENTS you could find the max time for a given object. Note to use this you need to set up log miner. Since you did not give a version try the Oracle 9i DBA Guide pg 9-1.

How to find out all the tables associated with particular T-code or Program
Hi All,
In 4.6B we have a transaction code SE49, where we can see all the tables associated with particular Transaction code or Program.
But in ECC 5.0 or in ECC 6.0 this transaction code is not available.So is there any alternative where i can find out all the tables associated with particular T-code or Program.
Thanks
ShubhamHi,
you are right, Transaction SE49 as well as SE48 do not exist anymore I'm afraid, they
are discontinued.
You might try to create a transaction variant:
1) Start SE93 to create a transaction variant
2) Specify a name, eg. ZSE49, and choose the first option:
"program and screen (dialog transaction)
3) Here specify SAPMSEUZ as program, and 200 as screen number
4) Choose a suitable development class (package) if you want it to be
transportable or Local (=$TMP) if non-transportable
5) press Save
Same applies for SE48, same program but dynpro 100.
Sorry for not being able the reasons behind the decision to discontinue
these transactions. I suppose at least part of the functionality was
integrated in SE38.
Best regards

How to find out where a table is used in the code ?
I have a huge database, and I am adding a column to a table...
is there a query to find out if this would impact the code ? I mean I want to find all the places in the code with
insert into mytable, or update mytable.....
how to include both insert into mytable, and update mytable in dba_source ?Use DBA_DEPENDENCIES:
select owner,name,type from dba_dependencies where referenced_name = 'TABLE_NAME'
and referenced_owner = 'TABLE_OWNER';For example:
SQL> select owner,name,type from dba_dependencies where referenced_name = 'EMP'
2 and referenced_owner = 'SCOTT';
OWNER NAME TYPE
PUBLIC TABLE1 SYNONYM
SCOTT SELECT_EMP PROCEDURE
SCOTT EMP_DEPT_VW VIEW
SCOTT PP SYNONYM
SCOTT EMP_MV MATERIALIZED VIEW
SCOTT EMP_VIEW VIEW
6 rows selected.
SQL> However, keep in mind DBA_DEPENDENCIES stores statis references only. If your code references table in question in dynamic SQL you will have to parse DBA_SOURCE and in some cases, even that will not give you all answers.
