Go to SAP system data → Click on component magnifying glass.

The following two options will be displayed :

• Installed Software Component Versions
• Installed Product Versions
• Under installed software component, you can see all the software installed, support package, service pack, description etc. If you want to check the details of each component, you can select the component and go to the details tab as shown above.
• Go to Installed Product Versions; it will show you the version of the installed SAP NetWeaver.

A client is used in SAP system for multiple login on a single instance. You can create multiple clients on a single instance. It also provides data security as one user with one client can’t see the data of the other user with another client and also there is no need to install the software again.

The following are the advantages of client administration in SAP system :

• Using SAP Clients, the same resources can be shared between multiple users.
• It helps you to manage SAP system landscape as you can create multiple clients for DEV, QA and PROD team.
• It allows you to share the SAP system with a large number of users.
• We have standard clients in SAP system

The following are the five different typ”]es of user types :

Dialog user : This user is used for interactive system access from GUI.

System user —:This user is used for background processing and communication within a system.

Communication user : This user is used for external RFC calls.

Service user —:This user is created for a larger and anonymous group of users.

Reference user : These are reference users with no logon possible, non-person related users that allow the assignment of additional authorizations.

You can set the number of incorrect login attempts and then system can end the session or can also lock the user account if parameter value is set by Administrator. There are two types of parameters used −

Static : This parameter doesn’t apply immediately and the system needs a Restart for this.

Dynamic −:This parameter can be applied directly and the system does not need a Restart.

To set the value of parameters, use transaction code — RZ11s

To set the number of failed attempts, use parameter — login/fails_to_session_end.

Likewise, you have other parameters such as login/fails_to_session_end, login/fails_to_user_lock

The following are the password policy parameters −

• login/min_password_lng
• login/password_expiration_time

Class A (High Priority) : This is used for urgent or critical tasks. These tasks must be scheduled with class A priority job. Class A job reserves one or more background work processes.

Class B (Medium Priority) : These jobs are executed after the completion of Class A high priority jobs.

Class C (Low Priority) : These jobs run once class A and class B jobs are completed.

To schedule a background job you must specify the conditions that will trigger the job to start.

The different types of start condition you want to use are −

• Immediate
• Date/Time
• After Job
• After Event
• At Operation Mode

The different types of status are – Scheduled, Released, Ready, Active, Finished, Cancelled

You can’t unschedule a job if it is active. You need to wait for the completion of the job to unscheduled it.

Transport directory /usr/sap/trans should have enough space.

Kernel is an executable program that exists between SAP Applications and operating system. It consists of executable program under the path — “/sapmnt/<SID>/exe” for UNIX and \usr\sap\SID\SYS\exe\run Windows. It starts and stops application services such as message server, dispatcher, etc.

In Kernel upgrade, new .exec files replace old executable files in SAP system. To check the current version, use Transaction SM51 and go to Release Notes.

To check the status, go to System → Status tab → Other Kernel info

• Job Processing and Scheduling
• User Management
• SAP system configuration and Client Administration
• Installation and Patch Upgrade
• Installation and Patch Upgrade
