Tools to Connect Remote Servers from Desktop

Hi ,

Unix:
1. Xmanager
2. PUTTY
Procedure to get display( SUSE Linux servers)
1.Setup environment variables

a) Set DISPLAY

Enable X11 forwarding in putty
Login with sidadm
Run “echo $DISPLAY” and make a note of the result
Run “ xauth list” and make a note of result Execute → xauth extract /tmp/d switch to root user ( sudo su – root )
Run “export DISPLAY=”
Run “xauth merge /tmp/d”
Run “xclock” to open clock for confirming the display settings
Example :
LONSAPVAS01:cc4adm 12> xclock
LONSAPVAS01:cc4adm 13> xauth list
LONSAPVAS01/unix:10 MIT-MAGIC-COOKIE-1 94d450329e0002d7988110433c257dff
LONSAPVAS01:cc4adm 14> echo $DISPLAY
localhost:10.0
LONSAPVAS01:cc4adm 15> xauth extract /tmp/jose
LONSAPVAS01/unix:10
LONSAPVAS01:cc4adm 17> sudo su - root
LONSAPVAS01:~ # export DISPLAY=localhost:10.0
LONSAPVAS01:~ # xauth merge /tmp/jose xauth: creating new authority file /root/.Xauthority
LONSAPVAS01:~ # xclock
LONSAPVAS01:~ # echo $DISPLAY localhost:10.0

b) Set environment variables From “root” user
export JAVA_HOME= /usr/java/j2sdk1.4.2_10
export PATH=$JAVA_HOME/bin:$PATH
export SAPINST_JRE_HOME=$JAVA_HOME/jre
All environment variable settings are done now. Proceed with start of SAP installation using “sapinst”

Windows:
1. Remote Desktop(MSTSC)
2. vnc viewer

Solaris 10 Commands

Hi All,
Here I am listing Some useful Unix-Solaris commands that can help you while administrating SAP with this combination:
1) /usr/sbin/prtconf grep Memory To Find Memory
2) To Check th Value of Variable rlim_fd_curadb -k /dev/ksyms
rlim_fd_cur/D *** This will display the current value
ctrl-D *** This quits you out of the debugger.
3) usermod example - Add a existing user to existing groupAdd existing user tony to ftp supplementary/secondary group with usermod command using - a option ~ i.e. add the user to the supplemental group(s). Use only with -G option :
# usermod -a -G ftp tony
4) Change existing user tony primary group to www# usermod -g www tony
5) Make is located at /usr/ccs/bin/make or you can download related version of make pkg from this freebe location. http://sunfreeware.com
6) rsh target_host -l username date :To check rsh is working or not
7) prtdiag to get system information
8) psrinfo to get cpu-count
9) isainfo to get system architecture

How to Lock or Unlock a Client in SAP

Hi All,
Here i am writing the procedure to lock and unlock a client in SAP,very rarely we need to use it..But stil u should know so follow these simple steps...
1) To lock or unlock a client in R/3 System, run the following function modules in
transaction se37
2. SSCR_LOCK_CLIENT ( to lock the client)
3. SSCR_UNLOCK_CLIENT (to unlock the client)
Run these functions with a client input which is to be locked/unlocked. This function set flag '' Client is locked temporarily for client copy" in client maintenance menu.The client will be available for users DDIC and SAP*. If any other user tries to login, system gives message that ' Client locked temporarily'.
To unlock the client
1. Run transaction SE37
2. Enter the function module as SSCR_UNLOCK_CLIENT
3. press F8 or test run (single run).
4. Specify the client and execute(F8).
Follow similar procedure for locking the client...

SAP Central User Administration(CUA)

Hi All,

Here is the procedure for Central user administration configuration in a landscape:
1) Create Logical systems to all clients for the landscape using BD54 or SALE ascomfortable.
2) Attach Logical system to clients using Same.
3) Create RFC connection to relevant systems with the same name as logical system name .
If you Logical system name is SIDCLNT100 for dev then create RFC connection to DEV with same name SIDCLNT100.
4) Let us suppose you Central system: DEVCLNT100Child system: QUACLNT200
5) Create user CUA_DEV_100 in devclnt100 system
4. Create user CUA_QUA_200 in quaclnt200 system.
Create RFC’s to child systems from central and central to child.
5) Now logon to central system and execute tcode scua to configure cua.
Enter the name of the distribution model: CUA
Press create
Enter ALL Child system RFC’s
Save your entries now result screen will appear
If you expand the nodes for
the individual systems, you normally see the following messages for
each system: .ALE distribution model was saved,. .Central User
Administration activated,. and .Text comparison was started.. If
problem messages are displayed here, follow the procedure in SAP
Note 333441:
6) Setting the Parameters for Field Distribution Enter Tcode SCUM in central system following screen will appearNow maintain your filed distribution and save it.You can use transaction SUCOMP to administer company address data.You can use transaction SCUG in the central system to perform thesynchronization activities between the central system and the childsystems by selecting your child system on the initial screen of transactionSCUG and then choosing Synchronize Company Addresses in the Central System
After you have synchronized the company addresses, you can transfer theusers from the newly connected child systems to central administration.
This is done, as with the synchronization of the company addresses, using
transaction SCUG in the central system. To do this, on the initial screen of
transaction SCUG, select your child system and choose the Copy Users to
the Central System button.
Use
You can use the report RSCCUSND from the central system of Central User Administration (CUA) to synchronize the master data of selected users with a child system of the CUA. The report sends the master data (including role and profile assignments) to a child system of the CUA.

If master data exists in the child system for the user sent, it is overwritten.
Procedure...
1. Start report RSCCUSND (for example, using transaction SA38).
2. In the Receiving System field, specify the child system to which you want to send the user data.
3. You can use the fields User and User Group to restrict the number of users.
4. Specify the data that you want to distribute under Distribution Options.
5. Choose Execute.

STMS Configuration

Hi,

What is the difference between a Transport Domain and a Transport group?
Transport domain and transport group does not having relationship.transport group is concern with transport directory not with transport domain.The SAP system containing the same transport directory arecalled to be in same transport group.That means in yourthree system landscape is having individual directoryconcept then there are three transport group in your systemlandscape. and if you are having concept of common transportdirectory in your system landscape then there is onetransport group in your system landscape.

Whereas a Domain Controller is the one box or SID which would control the transports going in from DEV to TEST and to PROD. Also the TP command is run from the domain controller.

Fist Steps SAP BASIS

Hi,

A transaction in SAP terminology is the execution of a program. The normal way of executing ABAP code in the SAP system is by entering a transaction code (for instance, SE51 is the code for the ABAP workbench). Transactions can be accessed via system-defined or user-specific, role-based menus. They can also be started by entering their transaction code (a mnemonic name of up to 20 characters) in the special command field, which is present in every SAP screen. Transactions can also be invoked programmatically by means of the ABAP statements CALL TRANSACTION and LEAVE TO TRANSACTION. Transaction codes can also be linked to screen elements or menu entries. Selecting such an element will start the transaction. The term "transaction" must not be misunderstood here: in the context just described, a transaction simply means calling and executing an ABAP program. In application programming, "transaction" often refers to an indivisible operation on data, which is either committed as a whole or undone (rolled back) as a whole. This concept exists in SAP but is there called a LUW (Logical Unit of Work). In the course of one transaction (program execution), there can be different LUWs.Let’s have a look at the different kind of transactions:

1) Dialog transactionThese are the most common kind of transactions. The transaction code of a dialog transaction is linked to a Dynpro of an ABAP program. When the transaction is called, the respective program is loaded and the Dynpro is called. Therefore, a dialog transaction calls a Dynpro sequence rather than a program. Only during the execution of the Dynpro flow logic are the dialog modules of the ABAP program itself are called. The program flow can differ from execution to execution. You can even assign different dialog transaction codes to one program.
2) Parameter transactionIn the definition of a parameter transaction code, a dialog transaction is linked with parameters. When you call a parameter transaction, the input fields of the initial Dynpro screen of the dialog transaction are filled with parameters. The display of the initial screen can be inhibited by specifying all mandatory input fields as parameters of the transaction.
3) Variant transactionIn the definition of a variant transaction code, a dialog transaction is linked with a transaction variant. When a variant transaction is accessed, the dialog transaction is called and executed with the transaction variant. In transaction variants, you can assign default values to the input fields on several Dynpro screens in a transaction, change the attributes of screen elements, and hide entire screens. Transaction variants are maintained in transaction SHD0.
4) Report transactionA report transaction is the transaction code wrapping for starting the reporting process. The transaction code of a report transaction must be linked with the selection screen of an executable program. When you execute a report transaction, the runtime environment internally executes the ABAP statement SUBMIT—more to come on that.
5) OO transactionA new kind of transaction as of release 6.10. The transaction code of an OO transaction is linked with a method of a local or global class. When the transaction is called, the corresponding program is loaded, for instance methods an object of the class is generated and the method is executed.
