How To Check Sap Kernel Version In Windows

What is a Kernel?

• The Kernel is a central program which acts every bit an interface between SAP awarding and operating system.
• The Kernel consists of the executable programs that reside under the path "/sapmnt/<SID>/exe" (UNIX) or \usr\sap\SID\SYS\exe\run (Windows)
• These files assist startup the R/iii system, initialize the memory, create buffers and start managing the requests from users and effectively utilizing of hardware resources.
• The kernel is too responsible for starting and stopping all the application services like dispatcher, message server, collector etc.

Why Kernel Upgrade?

• SAP Kernel is the cadre of the awarding. Like all other applications, the Kernel contains the executable files (.EXE files for stating diverse processes in SAP).
• The Kernel is the heart of the operating organization. It contains those files which are used to run every consequence in SAP. E.chiliad.|: starting database, shutdowns of the database, starting sap, shutdown of sap, saposcol, to uncar the sap files etc.
• That's the reason why when a Kernel upgrade is done it means new versions of the diverse EXE files supercede the older versions.

How to cheque Kernel Version?

There are many means to check the Kernel Version –

Method 1) Logon to SAP system and go to SM51 à Release Notes

Method ii) Logon to SAP system and go to System tab in the carte bar and select Condition

Method 3) Logon in operating system, switch to user <SID>adm and give the command disp+work

You tin can also give disp+work –version

Download Kernel from Service Marketplace

• Get to "SAP Service Market. " (https:\\service.sap.com) You will demand your OSS ID and password.
• Then go to Downloads à SAP Support Packages -> Entry By Application Group -> SAP Kernel 6.00 64 Scrap -> Select your OS (LINUX/WINDOWS/SOLARIS/AIX) -> Database Dependent and Database independent Kernel Patch.
• 2 SAR files SAPEXE.SAR and SAPEXEDB.SAR are downloaded from Service Market place.

Database Contained

Database Dependent: ORACLE

Kernel Upgrade Steps:

Step one: Create a new Directory at Os level with plenty infinite. Name of Dir tin can be "exe_new<ddmmyy>".

Step 2: Transfer these SAPEXEDB.SAR & SAPEXE.SAR files which you have downloaded to the new directory at Bone level.

Stride iii: Change your current directory to path .SAR files are created (cd /sapmnt/PR2/exe_new20122006). Check the directory path with command 'pwd' to ensure you are in the same dir (exe_new<ddmmyy>).

Stride iv: Now uncompress these. SAR files by sapcar exe. The command used for the same would be

SAPCAR –xvf sapexe. SAR

SAPCAR –xvf sapexedb.SAR

Step v:
At present create one more directory in that path with the name "exe_old<ddmmyy>". Take the fill-in of existing kernel.Re-create (simply copy not motility) the existing kernel from exe directory to "exe_old<ddmmyy>"

Pace 6: At present stop the SAP application. (For kernel upgrade the shutdown of database is non essential but we demand to stop the SAP awarding)

stopsap r3

Step vii:

Then copy the files from the new kernel directory exe_new<ddmmyy> to the existing kernel directory exe

cp -rp /sapmnt/<SID>/exe_new<ddmmyy>/* /sapmnt/<SID>/exe/

Step eight: This will copy / replace all the files in the existing kernel directory with a new kernel files.

Then check the kernel version from Os level by the command disp+work. Information technology should show that the patch number has been increased.

Stride 9:

Then logon to Os level equally root (specific to UNIX). In the kernel directory, there is a script called saproot.sh. Execute this script

./saproot.sh <SID>

Pace 10: This script assigns the correct permissions to all the executable programs in the kernel such br* file etc…

Step 11:

And then start the SAP organization

startsap r3

Step 12: Now you can besides check the kernel version level from SM51 or by selecting system à status
