Error in Kernel upgrade from 201 to 402

[Former Member]

Hi,

We are facing couple of issues with SAP kernel upgrade. We are upgrading the kernel from 201 to 402 with reference to the SAP Security Note 1800603

SAP Kernel 720 64bit

Windows 2008 64 bit x86

1. When we have upgraded the kernel application comes up fine and we are able to login as dialog user but on MMC console, dispatcher is in yellow color with the status as "Running but dialog queue info unavailable". Please see below screen shot

2. When we check the kernel version via disp+work or via application status it say kernel patch level to be 401 instead of 402. Please see below screen

Please provide your expert advise to resolve the issue.

Thanks!!!!

Hello SG,

It's not an error but a displaying issue and it's very common. Root cause: disp+work has already been updated but sapstartsrv is still on the previous version. You can control this by

sapcontrol -nr <instance nr.> -prot PIPE -function GetVersionInfo

by <sid>adm user. In the first two lines You'll see the path and version of sapstartsrv and disp+work. They won't be the same. You need to

- stop SAP

- stop sapstartsrv

- replace sapstartsrv (mind the path in sapcontrol output)

- start sapstartsrv

- start SAP

and voila, system in SAPMMC will turn to green.

That You see kernel patch level 401 in package 402 is normal as well, see SAP note 1820928.

Best regards,

Thanks Adam

The version of SAPSTARTSRV is still 201. Please suggest how to replace this file in the given path as new kernel donot have sapstartsrv

Chances are the file is ready to be copied, but you first have to restart the SAP services in your MMC or if you get the go ahead, reboot the server(s) and the 201 will go away.

Hello

The problem looks more likely with the old version of kernel files present at the DIR_EXECUTABLE location.

Check the version of sapstartsrv in the /usr/sap/SID/DVEBMGS00/exe location.

What you need to remember is to stop all the SAP services in services.msc when you replace the kernel files.
