An SAP system need to have more number of dialog work processes during the day instead of night. Because, Many users will work on their desktops to do their day-to-day transactions during the day. They have to interact with the system at faster rate. So they need more number of dialog work processes than background or any other work processes. Because less number of end users will interact with the SAP system during night, less number of dialog work processes are enough. During night time many background works will be carried out. That is, The system need more number of background work processes during night. We can do this assignment using the concept of Operation Modes. You can distribute work processes to each operation mode according to your company’s requirement and assign them to different time periods. You can Follow the steps given below to do experiment of creating and setting operation modes in an SAP system.

This topic is very easy to understand by doing above experiment 2-3 times. You will feel like it is very simple after understanding the concept. If you need online explanation of this topic, please contact me at punarvasi@gmail.com or fill the form below and send your message as comment to this blog post. I will fix an appointment for online class. There is a fee of 5 USD for this online one-to-one interactive class. I will demonstrate this topic by showing steps on live SAP system. I am also providing complete SAP basis training, with which you will get hands on experience on each and every topic of the SAP basis administration. So plan to join the SAP basis training. All the classes are one-to-one interactive.

We can edit system parameters in profile files which are stores at \usr\sap\<SAPSID>\SYS\profile directory. This method of changing is not recommended, because the user must ensure that the changes are performed and also should be documented properly. If you configure parameters wrongly in the system profiles, the instance may not start at all. To make easier profile administration, SAP has integrated profile administration or parameter maintenance option inside the SAP system. We can administer or maintain SAP system profiles using simple T-Code RZ10.

When the SAP system is initially installed, 3 profile files will be created at operating system level. We have to import them into the SAP database to administer them.

Steps to import profiles into SAP system

• Enter RZ10 (T-Code) in the command field in the SAP easy access menu
• Click ‘Utilities’ – ‘Select Profiles’ – Click ‘Of active servers’
• Display Profile Check Log will be displayed
• That means you have successfully imported profiles into the database
• Now you can change the parameters in the SAP system

During this import, the system performs a consistency check and a check of the way in which the parameters interact. Changes are stored in the database and written back to the OS file level. These changes are effected only when they are read by the system. These profile are read when the system is started. That means, You must restart the system to get the effect of the changed parameters. You can stop the SAP system using SAP Management Console, Shortcut will be available on the desktop of the server. There are three types of profiles available in each SAP system to make changes. I have explained about 3 types of profiles in my previous article. There are 3 levels to maintain the profiles. They are

• Administrative Data
• Basic maintenance
• Extended maintenance

Administrative Data: The administration data contains the type of profile, short description, the file path at OS level, name of the instance and the last activation time.

Basic maintenance: Basic maintenance allows you to adjust the most important parameters and supports the user through the use of logical descriptions.

Extended maintenance: Extended maintenance displays the technical names of the profile parameters. In extended maintenance, you can also add new or delete existing parameters.

Step-by-step procedure to change a profile parameter

• Select the profile type you want to change from the initial screen of RZ10
• Select the Edit profile level (Ex: Administrative, Basic or Extended maintenance)
• If you do not want to create new or delete existing parameter, Select Administrative or Basic maintenance and click display or change button. Display button will displays the parameter name and corresponding value. Change button allows you to change the parameter value
• If you want to create new parameter or delete existing parameter, select the Extended maintenance option
• After clicking on change button, You will get the screen where you can do many operations, such as creating a new parameter, deleting existing parameter or display existing parameter…etc
• After any modification, you have to click Copy button which is available on the Application toolbar, When you do this, the changes are temporarily copied
• Click profile from the menu bar and click exit
• The initial screen of the profile maintenance screen again will be displayed
• You can observe there is a version number field which will be incremented by 1 after clicking on the Save button in the Standard toolbar
• As soon as you click Save button, Activate profile dialog box will be displayed, Click Yes
• Now the Information box will be displayed. This information box is informing you that the changes are stored in the database and activated.
• You must be able to see the changes now in the profile files at OS level after performing above step
• Log off from the SAP system and restart the SAP system using SAP MMC
• You can check the changes by following same steps mentioned above. You may also use display button instead of Change button to view only changed parameter values.

Changes to the default profile takes effect only after a restart of all instances in the entire SAP system. Some of the advantages of administering profiles within the SAP system instead of editing direct OS level profile files, are as follows

• Central administration and maintenance of the instances is possible
• Changes in profiles can be checked for consistency
• We can have the facility of Administration of multiple versions of a profile
• We can compare actively used profile and the profile stored in the database
• Immediate activation of selected parameters

This topic is very easy to understand by reading carefully. You will feel like it is very simple after understanding the concept. If you need online explanation of this topic, please contact me at punarvasi@gmail.com or fill the form below and send your message as comment to this blog post. I will fix an appointment for online class. There is a fee of 5 USD for this online one-to-one interactive class. I will demonstrate this topic by showing steps on live SAP system.

SAP system is built up of one or more instances. Configuring these instances and therefore of the entire SAP system is performed using the different system parameters. Defaults of these parameter values are defined in the kernel’s program code.

We can change the default system parameter values defined in the kernel’s program code using profile files. The system will read these profile files while the instance is started. These profile files are created when the SAP system is installed. We can edit these profile files whenever we want using any type of editor. Because profiles files are read only when the system is started, we must restart the instance or entire sap system after changing any system parameter using profile files. Then only, the changed system parameter will take into effect.

Profile files are created in the operating system directory \usr\sap\<SAPSID>\SYS\profile. This directory can be read by SAP system using the share or mount technique. There are three type of system profiles will be created during sap system installation. They are…

• Start Profile- This profile specifies for each instance which processes are to be started. Structure of this profile file is START_<instace><instance number>_<host name>. Ex: Message server and dispatcher
• Default Profile – This profile is read by all the the instances. The default profile is only available for each SAP system. This profile file contains system-wide settings like default logon client, name of the database server and enqueue server. DEFAULT.PFL is the structure of this profile file.
• Instance Profile – The structure of the instance profile looks like <SAPSID>_<instance><instance number>_<host name>. This profile file defines parameters that apply to one instance. Ex: The number and type of work processes and the definition of size and allocation of main memory used.

How to display the current values of the System Parameters

There are 2 ways to do this operation in the SAP system. They are

• RZ11 (T-Code) Enter this T-code in the command field and hit enter. Type the system parameter and click Display button to get the value of the entered parameter.
• RSPFPAR – (Report) – You can run this report using T-Code SA38. Enter the Report name RSPFPAR, Enter the parameter that you want to know the details about. Click Execute button from the Application toolbar.

We can also display the values of the profile parameters at OS level using the user <sapsid>adm using the program sappfpar.

‘C:\sappfpar <parameter name>’ displays the current value of the parameter

‘C:\sappfpar all’ displays list of all the parameters

‘C:\sappfpar check’ We can check the parameter that are set

‘C:\sappfpar help’ displays the short overview of the possible options

This topic is straight forward to understand. You can understand this topic very easily if you read carefully. Once you got the concept, you will feel like it is very simple. To conclude above topic, there are default system parameters already defined in the kernel of the SAP system, The profile files are enables you to modify system parameters according to your requirement.
