Want help in understand Tcode

Hi,
I am new to SAP BASIS . I want to understand the Tcode functionalities . is there any books or links to study ..
For example in DB02 i can see many buttons like Space statistics ,Current sizes etc...
Please help me

first you will have to digitize the stream, then cut it up into packets of handlable size, then you just sent them out over a valid socket connection.
Yes, I know this is very simple, what part are you having toubles with?

Need help for understanding the behaviour of these 2 queries....

Hi,
I need your help for understanding the behaviour of following two queries.
The requirement is to repeat the values of the column in a table random no of times.
Eg. A table xyz is like -
create table xyz as
select 'A' || rownum my_col
from all_objects
where rownum < 6;
my_col
A1
A2
A3
A4
A5
I want to repeat each of these values (A1, A2,...A5) multiple times - randomly decide. I have written the following query..
with x as (select my_col, trunc(dbms_random.value(1,6)) repeat from xyz),
y as (select level lvl from dual connect by level < 6)
select my_col, lvl
from x, y
where lvl <= repeat
order by my_col, lvl
It gives output like
my_col lvl
A1     1
A1     3
A1     5
A2     1
A2     3
A2     5
A3     1
A3     3
A3     5
A4     1
A4     3
A4     5
A5     1
A5     3
A5     5
Here in the output, I am not getting rows like
A1     2
A1     4
A2     2
A2     4
Also, it has generated the same set of records for all the values (A1, A2,...,A5).
Now, if I store the randomly-decided value in the table like ---
create table xyz as
select 'A' || rownum my_col, trunc(dbms_random.value(1,6)) repeat
from all_objects
where rownum < 6;
my_col repeat
A1     4
A2     1
A3     5
A4     2
A5     2
And then run the query,
with x as (select my_col, repeat from xyz),
y as (select level lvl from dual connect by level < 6)
select my_col, lvl
from x, y
where lvl <= repeat
order by my_col, lvl
I will get the output, exactly what I want ---
my_col ....lvl
A1     1
A1     2
A1     3
A1     4
A2     1
A3     1
A3     2
A3     3
A3     4
A3     5
A4     1
A4     2
A5     1
A5     2
Why the first approach do not generate such output?
How can I get such a result without storing the repeat values?

If I've understood your requirement, the below will achieve it:
SQL> create table test(test varchar2(10));
Table created.
SQL> insert into test values('&test');
Enter value for test: bob
old   1: insert into test values('&test')
new   1: insert into test values('bob')
1 row created.
SQL> insert into test values('&test');
Enter value for test: terry
old   1: insert into test values('&test')
new   1: insert into test values('terry')
1 row created.
SQL> insert into test values('&test');
Enter value for test: steve
old   1: insert into test values('&test')
new   1: insert into test values('steve')
1 row created.
SQL> insert into test values('&test');
Enter value for test: roger
old   1: insert into test values('&test')
new   1: insert into test values('roger')
1 row created.
SQL> commit;
Commit complete.
SQL> select lpad(test,(ceil(dbms_random.value*10))*length(test),test) from test;
LPAD(TEST,(CEIL(DBMS_RANDOM.VALUE*10))*LENGTH(TEST),TEST)

Need help to understand INSTALL command based on GPspec 2.1.1

Hi Friends..
Sorry before, i couldn't understand some commands based on GPSpec 2.1.1, i'm pretty new in this field..
So, i need your help to help me understand about the commands..
Firstly, i want to know what exactly the DATA that referred by INSTALL Command..
here's outlined in the GPSpec 2.1.1 for INSTALL Command (Chapter 9)..
CLA = '80' or '84'
INS = 'E6'              //INSTALL
P1   = 'xx'               //Reference control parameter P1
P2   = '00'               //Reference control parameter P2
Lc   = 'xx'                //Length of data field
Data 'xxxx'           //Install data (and MAC if present)
Le   = '00'What exactly the data referred?.
I thought the data which referred can be Applets, Packages, CAP files..
So, how to know the LC and Sequence bytes of the Applets/ Packages/ CAP files..
i found this LINK..
In the website i read an example of INSTALL Command..
Here's an example mentioned in the link above..
INSTALL FOR LOAD
84 E6 02 00 2B 10 A0 00 00 00 18 50 00 00 00 00 00 00 52 41 44 50 00 00 0E EF 0C C6 02 00 00 C8 02 00 00 C7 02 00 00 00 2A 8B 3A 01 3C 8E FD A4 (00)
00, 90 00 [Normal ending of the command.] Sorry, i'm still not understand about it..
Please help me regarding this..
Sorry, perhaps this question sounds silly..
Thanks in advance..

Hi,
As a hint, you want to use INSTALL for install and make selectable. You can have a look at the APDU that GPShell sends through for the final install command (hint: it will be a part of the load command). You can also execute install_for_load, load and install_for_install in GPShell to see these commands. The GP card spec is a little confusing for the INSTALL command so tracing GPShell may help you understand it.

Help with understanding key event propagation

Hello,
I am hoping someone can help me understand a few things which are not clear to me with respect to handling of key events by Swing components. My understanding is summarized as:
(1) Components have 3 input maps which map keys to actions
one for when they are the focused component
one for when they are an ancestor of the focused component
one for when they are in the same window as the focused component
(2) Components have a single action map which contains actions to be fired by key events
(3) Key events go to the currently focused component
(4) Key events are consumed by the first matching action that is found
(5) Key events are sent up the containment hierarchy up to the window (in which case components with a matching mapping in the WHEN_IN_FOCUSED_WINDOW map are searched for)
(6) The first matching action handles the event which does not propagate further
I have a test class (source below) and I obtained the following console output:
Printing keyboard map for Cancel button
Level 0
Key: pressed C
Key: released SPACE
Key: pressed SPACE
Level 1
Key: pressed SPACE
Key: released SPACE
Printing keyboard map for Save button
Level 0
Key: pressed SPACE
Key: released SPACE
Level 1
Key: pressed SPACE
Key: released SPACE
Printing keyboard map for Main panel
Event: cancel // typed SPACE with Cancel button having focus
Event: save // typed SPACE with Save button having focus
Event: panel // typed 'C' with panel having focus
Event: panel // typed 'C' with Cancel button having focus
Event: panel // typed 'C' with Save button having focus
I do not understand the following aspects of its behaviour (tested on MacOSX although I believe the behaviour is not platform dependent):
(1) I assume that the actions are mapped to SPACE since the spacebar clicks the focused component but I don't explicitly set it?
(2) assuming (1) is as I described why are there two mappings, one for key pressed and one for key released yet the 'C' key action only has a key pressed set?
(3) assuming (1) and (2) are true then why don't I get the action fired twice when I typed the spacebar, once when I pressed SPACE and again when I released SPACE?
(4) I read that adding a dummy action with the value "none" (i.e. the action is the string 'none') should hide the underlying mappings for the given key, 'C' the my example so why when I focus the Cancel button and press the 'C' key do I get a console message from the underlying panel action (the last but one line in the output)?
Any help appreciated. The source is:

Use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the posted code retains its original formatting.
1) In the Metal LAF the space bar activates the button. In the Windows LAF the Enter key is used to activate the button. Therefore these bindings are added by the LAF.
2) The pressed binding paints the button in its pressed state. The released binding paint the button in its normal state. Thats why the LAF adds two bindings.
In your case you only added a single binding.
3) The ActionEvent is only fired when the key is released. Same as a mouse click. You can hold the mouse down as long as you want and the ActionEvent isn't generated until you release the mouse. In fact, if you move the mouse off of the button before releasing the button, the ActionEvent isn't even fired at all. The mouse pressed/released my be generated by the same component.
4) Read (or reread) the [url http://java.sun.com/docs/books/tutorial/uiswing/misc/keybinding.html#howto]How to Remove Key Bindings section. "none" is only used to override the default action of a component, it does not prevent the key stroke from being passed on to its parent.

Help with understanding initial admin account vs. directory admin

Hello,
I am hoping someone can help me understand the initial admin account created when I was first configuring my server, and the directory admin.
I have setup an advanced server, and when I was going through the initial setup I created an account that for this discussion I'll call "admin." Once the initial setup was finished I started using Workgroup manager to create accounts. I was informed that I should create a different directory admin so I did and for this discussion we'll call that account "diradmin."
I am curious why the initial account of admin does not show up in workgroup manager, and why it does not show up as an option in Server Admin to assign permissions.
Is this making any sense?
Any explanation is greatly appreciated.
Thank you,
Scott

Hi
Presumably you used the Server Setup Assistant to configure Services prior to bringing the Server online?
Not a good idea really. When choosing Advanced after the Server Software has been installed don't enable/configure any service apart from Remote Desktop. Once the Server setup is complete run all available updates. Once you've done that begin to configure required Services using Server Admin. Once you've done that begin to populate your directory nodes with users using WorkGroup Manager.
The key to understanding the two accounts (a) System Administrator (admin UID 501) and (b) Directory Administrator (diradmin UID 100) is understanding which directory node you want to provide services to. The 'Local' node and the server in general (putting aside the super user 'root') will always be admin. Once you promote the Server from Standalone to OD Master you effectively create another Directory in addition to the Local one. This LDAP Directory can be used for all sorts of things. Principally enabling directory and contact information (amongst other things) to be shared/accessed with users that exist in that node with an enhanced authentication system (Kerberos) not available in the Local node and if the Server is in a Standalone Role. This LDAP Directory is controlled by diradmin. You won't be able to use admin for the LDAP node but you can use diradmin for the server in general - although I would not advise it. You can use root for both nodes - again I would not advise it unless absolutely necessary. Basically use admin to log into the Server and do the day to day stuff and use diradmin for the LDAP. Get into the habit of never having both applications open unless you are going to use them. Once you are done, quit out of them and leave them alone.
To toggle between the two Directory nodes launch Workgroup Manager and click on the small blue globe below the main set of icons at the top and above the Users/Groups/Machines tabs. You should see at least 4 selections: Local, /LDAPv3/127.0.0.1, Search Policy and Other. If you don't see /LDAPv3/127.0.0.1 select Other and browse for it. If you still don't see it then you effectively don't have an OD Master. This will severely limit the ability of server to provide auot-mounting networked home folders as well as access to iCal Server's features amongst other things.
Finally if you truly want LDAP and everything that goes with it then your DNS Service - wherever its placed - has to be correctly conigured and tested. This link is for a post that explains how to achieve this simply using the interface:
http://discussions.apple.com/thread.jspa?threadID=1251475&tstart=45
Depending on your network environment it might not be appropriate for you? However stick with it as it is a long post and you may find it useful?

What is the point of dashboard??? help me understand please....

i still don't understand what the point of dashboard is. why would i want to use any of these neat little gadgets when i can just use a browser.
so if someone can please help me understand the point of why i would use a google widget instead of just using google on safari.
same goes with most of the little widgets.
i really wish i could find a reason to use it. every so often i will d/l some new neat looking widgets but i never use them. except maybe the one that helps copy album covers.

Personally, I agree with some widgets seeming pointless. I don't use any google widget or anything. It is just as easy to open Safari, like you said. However, I do find a number of widgets very helpful and informative. I use the Ski widget during the winter to check conditions - save's a little time because all I have to do is open dashboard instead of navigating to the website. Other widgets I use show me weather, new yahoo emails, alert me if a site has been updated, shows me upcoming iCal events, etc and they all serve to give me quick bits of information at the press of a button, and it's all in one place. In order to do what I just listed without Dashboard, I'd have to open a number of websites and applications.
So basically, Dashboard is a timesaver. If you don't find any use for it, there are ways to turn it off. However, many people, like me, do find various widgets that we use all the time... to each his own I guess.

PCI cards, Airport cards...help me understand what is what and why?

Help me understand this wireless network "card" hardware stuff.
I have a dual 867 MHz G4 that I want to set up for networking with a PC so that both machines can access the internet (via DSL).
As far as I know, my Mac does not have an airport card of any kind. I'm planning to buy a Lynksys WRT 54G2 wireless router. Do I need to also install an airport card, or PCI card in my G4 to make this all happen? And, if so, what is recommended that will work with my G4?
The guys at the Apple store are telling me that all I need is a wireless router, and don't have to install anything extra, but what I'm reading on these various networking threads, is that just the G4 and a wireless router will not do the trick. After reading lots of threads here, it's sounding like I have to jump through hoops to set up a usable, working network. The Apple guy says that this is easy and basic. I'm thinking that THEY are thinking in terms of a newer machine, maybe? They're all young guys who probably think that nothing goes back farther than the iMac.
One thing the Apple guys were pushing is Airport Extreme, but at $180, I somehow thing I can get there for much less than that.
To make a long story short (hah...too late for that), what exactly do I need as far as a card, router, etc., and where do I get the right stuff (links would be helpful) to set up a Mac/PC network using my old decrepit G4?

Hi-
Networking Macs and PCs
Setup a Home Network
Create a small Ethernet network
MacWireless
Check the above links, and you will be better educated in the basics and requirements of various networks.
The easiest, and least hardware intensive is the Ethernet network. Also, Ethernet is fast.
A note about Airport; you machine only accepts standard 802.11b Airport cards. In a word, very slow.
Airport Extreme, or 802.11g, is much faster, and 802.11n is the fastest available. To get 802.11g or 802.11n in your machine will require a PCI adapter.

Can anyone help me understand how font sizes work in Mail?

Hi
I am used to writing and sending emails in Arial 10 (on my PC using Outlook) - it seems like a professional sort of size to send to people.
So I have set the Mail Preferences Fonts to Arial 10 for the message font
But when I receive emails, the font is so small I can barely read it. I have a new 24" iMac and just cannot get to grips with keeping font sizes at a reasonable level between applications. And I though Mac was supposed to be joined up....
As I write the text of this posting, the font is a good size to read (although still looks blurred - see my other postings) - it is in Arial which I want.... But I cannot get Mail to wrk in the same way.
I do not want to change the font size to the email messages to a bigger font size, as I want my outgoing messages to be received in font size 10.
Please help me understand how this is all supposed to work in MAC? It was all so easy on a PC!

No, it is one of several unfathomable shortcomings in Mail that you are unable to set a minimum text viewing size. I too have 24in iMac and I have to enlarge each incoming message manually using Cmd+ and this is frankly Stone Age stuff, especially when dealing with hundreds of emails every day. Another very poor alternative is to use Ctrl and the scroll wheel to zoom in but your head will soon be spinning as the screen moves around.
FWIW, I am also dismayed that Apple has disabled the Contextual Menu in 3 of the 4 mail address fields. There must be some obscure justification for limiting CM copy and paste to just the Subject field but I just think it's risible.
And why can't I save a message I have just written to a place of my choosing? Instead I must save it to the Drafts folder or send it first and then Save As from the Sent mailbox. Is this someone's idea of fun?
I could go on about Mail's shortcomings but that's enough ranting for now...

Need help to understand about cluster

Hi,
I am a SQL developer, and need a little help to understand what clusters are. I never came across to create any cluster. Can someone plz help me with simple example, what is cluster and in which situation we create cluster?
Thanks

>
A cluster is used to store data from more than table together. The data would typically share the primary key. For example the scott DEPT and EMP table data is related based on the DEPTNO value so DEPTNO could be the cluster key.
If you created a cluster and then created copies of those tables in the cluster (e.g. myDEPT and myEMP) Oracle would store the dept and emp data for the same DEPTNO value together, even in the same block.
Then when you query dept and emp data using DEPTNO it will be faster to retrieve the DEPT and EMP data for that department since it is colocated in the same blocks.
The drawbacks are that when you only want data from one of the tables (e.g. emp) Oracle has to skip over the DEPT data since some of it will be in the same blocks that the EMP data is in.
So clusters and clustered tables are most useful when you always query multiple cluster tables using the cluster key. For some other operations they can be very inefficient.
See the Admin Guide for an example using the DEPT and EMP tables

26 rows selected.What I cannot understand is why the E-Rows is NULL for "CONNECT BY WITHOUT FILTERING (UNIQUE)" step and A-Rows shoots up to 42M for first case. The behaviour is the same for any number of UNION queries above two.
Can anyone please help me understand this and aid in tuning this accordingly? Also, I would be happy to know if there are better ways to generate the missing date range.

Satish

Can you help me understand the use of the word POSITION in TR and CFM?

Hi,
I am trying to have a view of typical BI reports in TR and TM/CFM so through my research I came to the following link:.
http://help.sap.com/saphelp_nw2004s/helpdata/en/62/08193c38f98e1ce10000000a11405a/frameset.htm
My problem on this link and other postings on this site seem to be the same. Can you help me understand the use of the word POSITIONS in these context:
1. Our client has asked for financial transaction reports in BW, such as position of Borrowings, Investments and Hedge Operations (TM data).
2. I have a requirement on, some reports related to Money Market (Fixed Term Deposits, Deposits at Notice) something on FSCM-Treasury and Risk Manager. These reports will be similar to that of Loans, i.e. Position statement, flow statement, etc.
3. The set of position values for a single position or a limited amount of positions can be reported by transactions TPM12 and TPM13 in R3.
4. 0CFM_C10 (Financial Positions Cube)
Do you have some simple report outputs to help clarify how the word POSITION is used in such environments?
Thanks

If I future buy 10 shares in company at £1 per share - at the end of the day my potential value is £10
The next day the shares drop tp £0.9 per share - I have a negative position - my shares are only worth £9
I haven;t bought them yet - but I have a negative position - ie if things stayed as they are - I am going to realise (ie end up with) a loss
Now you can use this for loans and foreign exchange banks as well...

Need help in understanding why so many gets and I/O

Hi there,
I have a sql file somewhat similar in structure to below:
delete from table emp;-- changed to Truncate table emp;
delete from table dept;--changed to Truncate table dept;
insert into emp values() select a,b,c from temp_emp,temp_dept where temp_emp.id=temp_dept.emp_id
update emp set emp_name=(select emp_name from dept where emp.id=dept.emp_id);
commit --only at the end
the above file takes about 9-10 hrs to complete its operation. and
the values from v$sql for the statement
update emp set emp_name=(select emp_name from dept where emp.id=dept.emp_id);
are as below:

1) how do i re-write this legacy script? and what should be done to improve performance?
2) Should i use PL/sql to re-write it?
3) Also help in understanding why a simple update statement is doing so many buffer gets and reading , Is this Read consistency Trap as i'm not committing anywhere in between or it is actually doing so much of work.
(assume dept table has cols emp_name and emp_id also)

update emp set emp_name=(select emp_name from dept where emp.id=dept.emp_id);I guess that these are masked table names ? Nobody would have emp_name in a dept table.
Can you re-format the output, using "code" tags ( [ or { }

Duplicate partitions, need help to understand and fix.

So I was looking for a USB that I plugged in and went into /media/usbhd-sdb4/miles and realized all its contents was from my home directory.
So I created a random file in my home directory to see if it would also update /media/usbhd-sdb4/miles , and it did.
Can someone help me understand what is happening?
Also if I can fuse sdb4 and sdb2 as one, and partition it as my home directory without losing its contents?
Below is some information that I think would be helpful.
Thank you.
