Created By : P. M. V. Subba Rao 1

PROFILESThe instance parameters play a very important role in the performance and the configuration ofthe R/3 system. These parameters are set in the profiles of the R/3 system

SAP provides you with three profiles :

1. DEFAULT.PFL2. Instance Profile (<SID>_<instance name>_<computer name>3. System Profile. ( Start_<instance name>_<computer name>

Each of these profiles has an important role to play in the configuration of the system

The parameters in these profiles can be added through various means. You add the parameterswith in the system using the profile maintenance tool or else you can use any editor (like the Editcommand) of the OS or you can you the utility SAPPAD which is provided by SAP.

Inserting the parameters using the profile maintenance tool is easier to use.

Profiles maintenance through R/3 has its own advantages like : You can save each saved changeas a version in the R/3 database, After you have inserted a new parameter it performs aconsistency check on the values supplied to the parameter, You can immediately activate thechanges made to the profiles etc.

One of the first jobs you need to immediately after installation is to import the profiles into theR/3 database.

Follow the path Tools à CCMS à Configuration à Profile Maintenance

Alternatively use the transaction code RZ10



Choose Utilities à Import Profiles à Of active servers

And the profiles will be imported into the R/3 database.

After importing the profiles the parameters become active. You can include new parameters usingthe profile maintenance tool.

To be on the safer side, copy the profiles to new names or at least generate a new version of theprofile. By doing this you can keep a safe set of profiles and you can return to these old profilesin case problems occur. These are the backup copies of the working profiles.

You can save the profiles under a new logical name (administration name) in the database. Thephysical assignment of the name is retained.



You can make copies of the profiles using the profile maintenance tool as well as using the OScommand (Copy).

To make a copy of the profile enter the profile name and then follow the path Profile à Copy orclick on the Copy icon on the toolbar of the transaction code RZ10 screen.

Enter a profile name and click on the copy button / icon.

The new profile is generated in the database.



After you create a profile, you need to maintain the profiles. This is done in three stages :

1. First maintain the administrative data of the profile.

Select the profile and click on the Administrative Data radiobutton and click on the Changebutton

The administrative data consists of a short description of the profile indicating the purpose of theprofile, location of the profile on the OS level, type of profile etc.

After entering the administrative information click on the Copy icon on the toolbar.

The first version of the profile will be generated.

2. The second stage is to maintain the Basic Data of the profile.

Select the profile , click on the Basic Data radiobutton and click on the Change button



The appearance of the basic maintenance tool depends on the type of profile. Basic Datamaintenance allows you to only modify the most important parameters and provide the user withlogical names of the parameters.

3. The third one is the Extended Maintenance stage.

Select the profile , click on the Extended maintenance radiobuttton and click on the Change button

In the Extended maintenance mode you can change the values of the existing parameters, includenew parameters, delete parameters etc.



To include a new parameter in the profile, click on the Create icon on the toolbar of the abovescreen :

Enter the parameter and its value and then click on the Copy icon on the application toolbar.

Click on the Back icon to come out.

You will come to the parameters list screen. Now you should be able to see the parameter youjust created in the list.



Like this you can include parameters in the profile.

If you want to change the values of the of parameter then select the parameter and click on theChange icon.

Or else you can change the value on the right column.

After making the changes in the profile, click on the Copy icon



You will get the message ‘The changed profile was transferred’.

Click on the Back icon. You will come out of the Extended maintenance screen.

After coming back to the initial screen, click on the Save icon.

You will be prompted to activate the profile

Click on Yes.

The profiles gets activated



Click on the Enter / Continue icon. You will get a Caution message box.

Click on the Enter / Continue icon.

The changes are made permanent and the profile version number changes.



The changes that you make in the profiles are not effective immediately after activation. In makethe changes effective, the SAP instance i.e. the SAP Service Manager should be restarted again.

Now let us see what you can do with the instance profile.

In the RZ10 screen select the Instance profile, click on the Basic Data radiobutton and then clickon the Change button

Here you can change the buffer sizes and the no. of various processes like the update (V1 & V2),dialog processes etc. running on the system.

You can increase or decrease the values by clicking on the angular symbol buttons.

After making the changes click the Copy icon on the application toolbar. Come out of themaintenance screen and activate the changes.



There are some parameters, which can be changed while the system is running.

To find out which are these parameters, follow Profile à Dyn. Switching à Display parametersin the RZ10 screen

To have these parameters take immediate effects choose Profile à Dyn. Switching à Execute

Click on the Continue icon



To find out which parameters are currently active in your R/3 system, execute the reportRSPARAM. This report generates a list that displays both values for each parameter.

You can also display of list of currently active parameters at the OS level using the programsappfpar.

The sappfpar help command gives you a brief overview of the programs options :



For example

Sappfpar all command will list al the defined parameters.

You can also check the memory limits using the program memlimits at the OS level.

It compares the main memory requirements of the R/3 system, calculated from the parametersettings, with the defined kernel parameters of the operating system. If the R/3 requirementsexceed the limits defined in the operating system, problems may occur, or you may even not beable to start the R/3 system/



You can also delete the profiles that you created.

Select the profile and choose Profile à Delete

You will have two options of deleting the profile Individual profile and All versions

Choose Individual profile

Click on Yes.

You will be prompted for changes on the OS level,



click on Yes

Only the selected version of the profile will be deleted.

If you want to delete all the versions of the profile then select All Versions à of a profile fromthe delete menu path.
