How to find accurate number of Rows, and size of all the tables of a Schema

HI,
How to find the accurate number of Rows, and size of all the tables of a Schema ????
Thanks.

SELECT t.table_name AS "Table Name",
t.num_rows AS "Rows",
t.avg_row_len AS "Avg Row Len",
Trunc((t.blocks * p.value)/1024) AS "Size KB",
t.last_analyzed AS "Last Analyzed"
FROM dba_tables t,
v$parameter p
WHERE t.owner = Decode(Upper('&1'), 'ALL', t.owner, Upper('&1'))
AND p.name = 'db_block_size'
ORDER by 4 desc nulls last;
## Gather schema stats
begin
dbms_stats.gather_schema_stats(ownname=>'SYSLOG');
end;
## Gather a particular table stats of a schema
begin
DBMS_STATS.gather_table_stats(ownname=>'syslog',tabname=>'logs');
end;

HOW WE FIND OUT OPEN PURCHASE ORDER AND CLOSED PURCHASE IN THE TABLE?

HI,
PLZZ HELP ME.
what are fields names for open purchase order and closed purchase order
thanks

Hi param,
Go to mseg table, pass the purchase order number and purchase order item. if the mseg-menge = ekpo-menge for the corresponding purchase order then consider the purchase order is close, else it is still open. even check if the entries are not there for corresponding purchase order in mseg table then also it is open.
select mblnr zeile matnr menge from mseg into it_mseg where ebeln = it_ekko-ebeln
and ebelp = it_ekpo-ebeln.
if sy-subrc <> 0.
then consider the purchase order is open.
This is the first case.
even u can consider like this
if sy-subrc = 0.
if it_ekpo-menge > it_mseg-menge.
then also the purchase order is open.

How to find out number of background work processe available in the system?

Hi All,
I have a FM that triggers a background job using JOB_OPEN, ABAP_SUBMIT and JOB_CLOSE. But the problem is if there are no background work processes available at that moment, it does not return error. Not sure whether the job is even scheduled!
Is there a way to find out if there are any background work processes available in the system? I know a FM SPBT_INITIALIZE which gives info about dialog work processes. Is there any other FM similar to this which gives info about background wp??
Regards,
Shailesh

your Job will remain in a queue by message handler. once workprocess is free, your job gets scheduled
by the way, you can use the functionality used in FM TH_DISPLAY_WORKPROCESS_LIST to read the workprocesses
the command which gets you the workprocess is:
CALL 'ThWpInfo' ID 'OPCODE' FIELD OPCODE_WP_LIST
ID 'TAB' FIELD LIST_STATE_WPLST-TABL
ID 'CPU' FIELD LIST_STATE_WPLST-CPU.
check how its written in include LSDEBF01, form SET_LIST_WPLST

Smartforms table: how to fix the number of rows to be display in the table.

Hello.
I´m having problems with a smartform. I have defined a window with 7 cm high. Then I have define a table to print the content of a table.
I'm using the header, the main area, and the footer. It seems to be ok. But the main area is sizeble. I mean, that if in the table has 2 records, it dispaly the 2 records and inmediatly display the footer. It probably use only 3 cm of the 7 cm defined for the high of the window.
And I want that the footer of the table would be display at the end of the 7 cm of the window. Is that posible ?
Please, tomorrow we will have our kick off the module and this is the last issue we have.
Thanks in advance for your help.

Better idea wud be to create a WINDOW, just Below you Main window (After table) ..
In Form Layout (Form Painter) you can fix this Window on any place , Pass the FOOTER text node over there .. So you will get a Static FOOTER diplay ..
That what you need ?? Let me know

How can I keep iPhone 5 mute and viberated for all the sounds and notifications with the mute button on?

If turn on the mute button, my iphone 5 is mute. But I can not get informed if the alarm or timer ends. iPhone 5 is mute and doesn't viberate. I want it mute but viberate under the mute button.
The Timer cann't viberate with the mute button on. I want it viberates without sound especially when I study in the Liberaby. I need to practice my pace with the Timer. I don't know whether it is because of my mistaken operation or because of the fact that the iPhone 5 can not make it.
I think it should work like this, the mute button can mute all the sounds and notifications and at the same time, the phone can viberate to keep me informed when a new email comes or there is a twett or the timer ends with viberation.

How to find my my iphone 4S and iphone 4 using the Iphone Finder Apps?

How can we use the Iphone Finder to find multiple units of Iphone 4s?

Apple - iPhone 4S - Locate your missing iPhone with Find My iPhone - http://www.apple.com/iphone/built-in-apps/find-my-iphone.html But I think that only does one phone at a time because it isn't designed as a general person tracking feature.
Or are you just trying keep track of a group of phones in a general sense? I believe there is a Friends app (can't remember the name) which lets "friends" permit other friends to send a request to a phone to let the phone show where it is located.
Sometimes it helps to put this kind of question in more context because rather than getting just an answer to your question you may get a solution to the issue.

How to move all the tables from one tablespace to other for a whole schema

Hi,
Is there any way to move all the tables in a schema from one tablespace to other?
If so please help me out to do that.
Thanks
Regards
Gatha

hi,
here is the steps to move SCOTT's objects from their current tablespace to a NEW_TABLESPACE
would be:
1) do an export of all of scott's objects. Make sure no one modifies them after you
begin this process. You will lose these changes if they do.
$ exp userid=scott/tiger owner=scott
2) you would drop all of scotts tables. This will get the indexes as well. I don't
suggest dropping the user SCOTT but rather dropping scott's objects. Dropping scott
would cause any system priveleges SCOTT has to disappear and the import would not restore
them. This script can be used to drop someones tables:
set heading off
set feedback off
set verify off
set echo off
spool tmp.sql
select 'drop table &1..' || table_name || ' cascade constraints;'
from dba_tables
where owner = upper('&1')
spool off
@tmp.sql
3) You would modify the user to not have unlimited tablespace (else the IMP will just
put the objects right back into the tablespace they came from) and then give them
unlimited quota's on the new tablespace you want the objects to go into and on their
temporary tablespace (for the sorts the index creates will do)
alter user SCOTT default tablespace NEW_TABLESPACE
revoke unlimited tablespace from SCOTT
alter user SCOTT quota unlimited on NEW_TABLESPACE
alter user SCOTT quota unlimited on SCOTTS_TEMPORARY_TABLESPACE
4) you will IMP the data back in for that user. IMP will rewrite the create statements
to use the users default tablespace when it discovers that it cannot create the objects
in their original tablespace. Please make sure to review the file imp.log after you do
this for any and all errors after you import.
imp userid=scott/tiger full=y ignore=y log=imp.log
5) you can optionally restore 'unlimited tablespace' to this user (or not). If you do
not, this user can only create objects in this new tablespace and temp (which in itself
is not a bad thing)...

Find Total Number of Rows in Database

I am trying to find total number of rows in Database? Thanks in advance

I'd come back to a question of "why". What possible reason could you have to want to know the number of rows in every table in the database?
This seems like it is a request from someone non-technical where they're not sure exactly what they need to ask to get the information they want. I'm forseeing something along the lines of
User: How many rows are in the database
DBA: Ummm.... <<goes off and spends a lot of resources to count>>> ... 1 billion.
User: Wow, that's a lot... How big are those rows...
DBA: Hmmm... <<goes off and spends more time trying to find an average row size>>... 100 bytes
User: <<Plugs numbers into Excel>>... OK, our database is 93 GB, so we need to order 100 GB of disk for our new environment.
DBA: <<Months later, after 100 GB of disk has been budgeted, purchased, and delivered>> User, you didn't order enough disk for our disaster recovery environment.
User: You said our database was only 93 GB!!
DBA: 93 GB of data. Plus 100 GB of indexes, TEMP, UNDO, space for archived logs, ...
When "odd" requests come down, it's generally the case that the person asking the question doesn't know what question they really want to ask because they don't have the domain knowledge to know how to ask the question. Walking over and asking them what they're hoping to accomplish/ what they're using the data for generally leads to a case where
- The user gets exactly the information they need, not the information they think they want
- The DBA does a lot less work, since the right question is almost always easier to answer
- The user thinks of the DBA as a really helpful sort of guy and remembers how helpful you were in the past when you have to push back on other things later
- No one ends up playing the blame game when the user gets just what they asked for and not what they want.

Setting number of rows and columns

How do I set the number of rows and columns of a table, say 2348 rows by 3 columns?
Then how do I quickly select the last row?
Also, if I enter a formula in row 1 column 2, how do I quickly copy that formula down to row 1435, or to the end of the column? Dragging seems slow and awkward.

I wish to add a few words to Jerrold responce.

The process that you describe is inefficient.
The efficient one is :
create a table
enter the formulas in a single row
delete the rows below.
Now, each newly inserted row will contain the formulas.
From my point of view, it's when this is done that it will be interesting to apply a script adding rows.
Here is a script inserting rows.
--[SCRIPT insertRows]
Enregistrer le script en tant que Script : insertRows.scpt
déplacer le fichier ainsi créé dans le dossier
<VolumeDeDémarrage>:Users:<votreCompte>:Library:Scripts:Applications:Numbers:
Il vous faudra peut-être créer le dossier Numbers et peut-être même le dossier Applications.
Sélectionner une cellule au-dessous de laquelle vous voulez insérer des lignes.
menu Scripts > Numbers > insertRows
Le script vous demande le nombre de lignes désiré puit insère celles-ci.
--=====
L'aide du Finder explique:
L'Utilitaire AppleScript permet d'activer le Menu des scripts :
Ouvrez l'Utilitaire AppleScript situé dans le dossier Applications/AppleScript.
Cochez la case "Afficher le menu des scripts dans la barre de menus".
--=====
Save the script as a Script: insertRows.scpt
Move the newly created file into the folder:
<startup Volume>:Users:<yourAccount>:Library:Scripts:Applications:Numbers:
Maybe you would have to create the folder Numbers and even the folder Applications by yourself.
Select a cell below which you want to insert rows.
menu Scripts > Numbers > insertRows
The script ask you the number of rows to insert then it does the required insertion.
--=====
The Finder's Help explains:
To make the Script menu appear:
Open the AppleScript utility located in Applications/AppleScript.
Select the "Show Script Menu in menu bar" checkbox.
Save this script as a … Script in the "Folder Actions Scripts" folder
<startupVolume>:Library:Scripts:Folder Action Scripts:

Maximum number of rows and columns in data form

Hi,
I wanted to know if there is a limitation to the number of rows and columns that can be displayed in a data form, in Hyperion planning 11.1.2.1 ?
And what would be the most appropriate number of rows and columns to be included for optimum performance.
Thanks.

Hi,
While its a fun fact to determine how much one can stuff into a web form, the reality is: how much can a user reasonably consume in a web form?
And what would be the most appropriate number of rows and columns to be included for optimum performance
You will find that the answer to this is by "what design makes a web form most usable?" And no, the users don't really know what they want from a design perspective, they see it in their head, but usually what they ask for is something that would look entirely different (huge).
The next thing to think about is the use of member selection functions in the page axis. IDescendants(Entity) in a dropdown could cause issues just as easily as too many rows - and again make the drop down unusable for a user.
If your question is a bit more technical, then consider this (somewhat oversimplified): Web forms are constructed by a process on the server. Objects are created based on the form's definition and used by the process that builds the form. The process uses Cartesian looping (lots of iterations) to construct the form cell by cell, starting at the top left and finishing up in the bottom right. If the form has a million cells on it, then the loop and all the code within it runs a million times. The capability of the server has a lot to do with how well it can handle this request, and how many it can handle at one time.
The result of this is gobs of HTML and JavaScript. All of this has to be sent over a network to the requesting client. The client starts receiving the web page code and has to render it in the browser and run the JavaScript. The ability to do this is limited by the browser, the OS, and the hardware that the client is running on.
And that's just rendering the page for use.
Now it has to be interacted with on the client machine, and changes parsed, packaged, and sent back to the server.
So the technical answer is, there can be many limitations to how many rows and columns a data form can have - none of which can truly be anticipated by anyone. This is why I put the part about usability first in this post.
