Error Application in Upgrade Kernel SAP - LINUX

[former_member689150]

Hello,

By making the environment kernel upgrade SAP ECC production with the same kernel version already updated in the DEV and QAS environments, three applications had problems with the upgrade.

The central instance and 4 applications have been successfully updated.

System: x86_64 GNU/Linux

The current kernel is:

version: 720_REL Patch: 319 Date: 03 / Oct / 2012

The new kernel:

version: 721_REL Patch: 323 Date: 30 / August / 2014

Below the error that occurs in aplications that presented problems, has anyone had any similar problem?

*** LOG Q1K => MsIAttachEx: STOC check failed, Kernel not compatible with system (rc = 29) [msxxi.c 820]

*** ERROR => Kernel incompatible already connected to instances (see dev_ms for details) [dpxxdisp.c 12599]

Thank you!

Switch back to old kernel, find your correct targer kernel and read it's relevant notes. Update your kernel correctly and check sapcpe.log files for any issues. If the sync fails, run sapcpe manually. Make sure services files are updated.

Hi,

Make sure that the below entry exists in services file.

sapmsSID    3600/tcp    # SAP System Message Server Port

Also do a manual sync with the below cmd

sapcpe pf=/usr/sap/<SAPSID>/SYS/profile/<instance profile>

Hi Ronaldo,

Kindly follow SAP Notes  1549673 - Kernel version not compatible with system

and  1716826 - Usage of the downward compatible kernel 721 (EXT)

You could try to patch the existing kernel and check again under dev_disp trace.

Regards,

Hi Ronaldo,

Open the DEFAULT.PFL and then change the parameter rdisp/msserv = sapms<SID> to rdisp/msserv = 0

Also do paste the dev_ms.

If it doesn't work after changing the parameter then there is some problem with the kernel binaries.

Download the fresh kernel and then run the

sapcpe pf=<for each instances>

then restart the servers

Then try to start the instances.

With Regards
