Kernel incompatible to already connected instances

[former_member211727]

Hi Experts,

The Dialog instance of our netweaver server is not starting with the following error:

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

I have already followed the below Wiki steps:

How to check

To check the 'source id'

1. Logon to central instance and execute

• sappfpar pf=<CI's profile> DIR_EXECUTABLE
• <DIR_EXECUTABLE>/msg_server | grep source

2. Logon to application server and execute

• sappfpar pf=<DI's profile> DIR_EXECUTABLE
• <DIR_EXECUTABLE>/disp+work | grep source

the source_id matches but still getting the same error. Please suggest.

Thanks

Hello,

Are the parameters "rdisp/mshost" and "rdisp/msserv_internal" defined at the DEFAULT.PFL profile only?

At the DI, when you perform a DNS test (e.g., "ping"), is the hostname defined at "rdisp/mshost" pointing to the correct IP address?

Attached is the dev_ms log.

Thanks

Hi Rahul.

Thanks for your info,

1. Could you share the OS / DB & SAP version details?

2. Could you refer the SAP KBA for the error message

igISetDefaultAction : default handling for signal SIGCHLD

Hi Rahul,

Please try few of these things:

1. stopsap

2A) Cleanipc, ipcs -a| grep sidadm, ipcrm -m <##>, ipcrm -s <##>

2B). cd /tmp; ls -ltr .sapstream* ; rm .sapstream* [remove all of them owned by sidadm]

3. Please, comment out the parameter 'ms/http_port' in Default profile and define 'ms/server_port_n' parameter (If you have separate ASCS define it in ASCS profile).

4. Double check services file:

sapmsSID    3600/tcp    # SAP System Message Server Port

5. Download the kernel again from SMP.

6. Apply it. Please use sapcpe to apply kernel files in all locations.

7. Make sure parameter is rdisp/msserv_internal=39nn in Default profile.

8. Startsap

Regards,

Sujit K Banerjee.

Hi Rahul,

Please try a clean stop and start of CI & App instance. There are errors in dev_ms file regarding cleanup.

[Thr 01] ***LOG Q0I=> NiIBindSocket: could not delete file '/tmp/.sapstream3600' for hdl 17: unlink (1: Not owner) [nixxi.cpp 3715]

[Thr 01] *** ERROR => NiIBindSocket: could not delete file '/tmp/.sapstream3600' (hdl 17; errno=0) [nixxi.cpp    3720]

Please stop all SAP application & database instance. Stop all active processes Cleanup/Delete .sapstream* files from /tmp file system (both CI & App server). These are hidden files, so please check accordingly and delete all existing files.

Start your listener,database,CI & App and update if you still facing same issue.

Hello MPS,

We usually do not repeat same steps in same post. I already mentioned in step 2B in the above post.

Thanks.

Hi Rahul,

Please update the OS for your Central Instance and dialog instance.

If your CI and DIA are on separate hosts then are you using same kernel including patch?

Thanks,

MPS

[former_member211727]

Hi Manish,

Yes, CI and DI are running on different hosts. The kernel including patch matches on both servers.

Hi Rahul,

Both CI & DIA instances are on AIX? and your system is Non-Unicode?

Have you recently upgraded SAP Kernel.

Thanks,

HI Raghul.

1. Could you attach the dev_ms.log

2 Share the SAP version details?
