Apologies for the detour, as I could not upload any more images.

Upgrading SAP Kernel from Release 700 to SAP Kernel 720_REL / 720_EXT Part I of II

Deploy the IGSHELPER.SAR to the relevant local directory /usr/sap/<SID>/<INSTANCE> on every instance as shown below:

Now switch to user root and run shell script saproot.sh from the kernel directory

Delete all the local executable's on the individual instances. To do this switch to local relevant executable directory /usr/sap/<SID>/<INSTANCE>/exe/ and execute rm -rf *


Since the executables from the local executable directory can be executed for the start before SAPCPE runs, start an initial copy of the executables.

For all application server instances (PAS, CI, AAS, DI, CI) & For Java Only Systems, perform the below:

If your system is running with the SAPJVM:

sapcpe pf=/usr/sap/<SID>/SYS/profile/<instance profile> source:<sapjvm directory> list:<sapjvm directory>/sapjvm_<version>.lst

Checking if the SAP system is using SAP JVM or 3rd Party JDK?

Execute SAPCPE now to sync the kernel directory:

Follow-up Activities

This step only applies to release 7.00 and 7.01 Dual-stack and Java only systems.

In all (Dxx, DVEBMGSxx, Jxx, JCxx etc) instance profiles, you must set the following parameter:

FN_JSTART= jcontrol$(FT_EXE)


You can start your SAP System now with the new SAP Kernel 720 (Check R3trans -x, Oracle DB & Listener should be up and running)

Well, WHAT DID JUST HAPPENED :shock: ?

I just switched to Local Instance Kernel directories and observed that all the executables were not replicated from the Global Kernel directory.

SAPCPE only replicated the JVM and other executables.

So, I manually copy all the executables from the Global Kernel Directory to all the Local Instance Specific Executable directories, and started the SAP system.

Voila. the SAP system started up like a champ :smile:

And the SAP Kernel has been successfully upgraded to SAP KERNEL 720_REL Patch Level 401.

Best Regards,

Akshay.
