Problem with Kernel upgrade

[Former Member]

Hello

We were upgrading the SAP Kernel 720 from 201 to 402. We have shut down the application and the SAP services and replaced the old kernel directory with the new one.

But when we tried to start the application and services we found two issues

1. Service SAPDAA_97 is not starting.

2. Disp+work is yellow and says " Runnig but dialog queue information unavailable"

Applicationis up and running but we have above issues and also if we check the kernel version in status it says 201 while the disp+work command says 401.

Also there is new sapstartsrv file in kernel dir which is generally the cause of this error.

Please assist as quickly as possible.

Thanks in Advance

Hi All,

Thanks for your support

I have copied the new exe to the DVEBMGS00\exe directory. It is not the normal procedure to do kernel upgrade but it seems to be working fine now.

Hello

I don't see any trace files provided to analyze the issue.

1. Service SAPDAA_97 is not starting.
This is for the SMD

sapcontrol -nr 00 -function GetVersionInfo

Replace 00 with the right system number.

Do you have SCS installed separately ?

ls -la /usr/sap/SID

HI Reagan,

Please find below the result of get version info disp+work is still 201 but i can confirm that we have new kerne; exe in NTAMD64. Do we need to replace it in DVEBMGS00\exe as well? If yes what else i need to do as we have never seen this in kernel upgrade.

Hi Saurabh,

Yes, Please switch the kernel in DVEBMGS00\exe.

Generally this should be taken care by sapcpe program while instance is started. Seems sapcpe is not properly configured/working.

http://help.sap.com/saphelp_nw04/helpdata/en/4f/37783021fc11d288cd0000e83539c3/content.htm

Please change kernel manually in both path(global as well as local) and restart the instance.

Hello Saurabh

From the output provided it is clear that most of the kernel files are still on 201 patch level.

I suggest you download the SAPEXE and SAPEXEDB for patch level 401 and extract them to these locations

F:\usr\sap\XYZ\SYS\exe\nuc\NTAMD64

F:\usr\sap\XYZ\DVEBMGS00\exe

Hi Saurabh,

Please check your Instance/Start profile.

Probably someone hash out sapcpe code lines(to sync global and local kernel)

Hello Saurabh,

try this:

stop SAP

stop SAPMMC

shutdown SAP[SID]_XX service

then:

Start -> Run -> CMD

sapstartsrv.exe

Enter all information

then start SAP[SID]_XX service

start SAPMMC

start SAP in SAPMMC

wait 2 minutes, check status, it should be green

if this does not work, check SAP note 72248 for more steps.

Hi George,

We are starting and stopping the SAP vai command prommt not by MMC as our MMC has some issues.

We will try your solution but will the application turn green even if the SAPDAA_97 service is down

Thanks!!!

Hi Saurabh

New Kernel disp+work is showing 401 is not a problem.

Please check the Note 1820928 - Known regressions in kernel 7.20 patch level 402

Is it ABAP only or Dual Stack system?

Hi Surojit,

Our system is ABAP Stack only and the note have generic kernel proble but doesnot deals with our issue,

Is SAPDAA_97 services has nothing to do with this?

Thanks!!!

Hi SG

ABAP kernel has nothing to do with DAA Agent.

Please try to start ABAP/DAA system using sapcontron commands

sapcontrol -nr xx -function GetProcessList

sapcontrol -nr xx -function StartService <SID>

sapcontrol -nr xx -function Start

where xx is instance number
