Java Kernel

Hello,

We have just performed Kernel upgrade on Netweaver 7.0 ABAP+Java system.

We just replaced the /usr/sap/SID/SYS/exe/run folder with teh new kernel.

It was successful and in ABAP we can see the new kernel.

But in Java, in System Information, it does not reflect teh same patch level.

In ABAP it shows Kernel 700 Patch 179

In Java it says a different patch level 109884.0

Can you tell me why in Java it does not reflect teh same kernel patch level?

Thanks.

First of all please always update the directory /sapmnt/SID/exe for kernel upgrade.

Please check the kernel patch level for the java from JSPM.

Thanks

This isn't a kernel version, this is the version of your j2ee engine. In a dual stack installation the abap and j2ee share the same kernel (also remember there is an additional SCS instance) .

For the J2EE you can for example use JSPM to verify the kernel version. After you started JSPM, switch to tab "Deployed Componenets", there you see com.sap/SAP KERNEL

Thanks mho,

So, is JSPM the only way to determine teh version of Java kernel?

Or, if its is saying in ABAP that the kernel has been updated, then I should belive taht Java kernel is also upgraded?

Correct, because it is the same kernel. As you might be aware that sapcpe does the synchrozing the respective directories.

No it is not the only way, you can do a disp+work -V, or check certain log files like dev_w0. Sadly in the J2EE component info page the version is not shown, but the traditional disp+work patch level is not very relevant to a J2EE as there are no workprocesses.

Besides that you can always verify and compare the executables on the server itself. But as long as you are not suspecting a problem you can savely assume that everything is ok.

Best regards, Michael
