Error in Upgrade in Downtime: MAIN_NEWBAS/GETSYNC_SECMIG_FIN.

Hi,

we are upgrading our BI System to NW 7.3 version. In the Downtime phase

under ABAP, we get the following error in step

MAIN_NEWBAS/GETSYNC_SECMIG_FIN:

Unable to execute the SDT request Java_EE operation execute on hostname

applpzcbwp instance 02 Initialization of sync events failed. See

following messages. Preparing execution of modules

DOWNTIME_START,STOP_SHADOW_INSTANCES,OFFLINE_MIGRATION,DATABASE_SWITCH,FS_UPDATE,SAPJVM_UPDATE,GLOBAL_DIRECTORY_UPDATE,DOWNTIME,PREPARE_FOR_APPL_MIGRATION,SWITCH_SUPER_ADMIN,DEPLOYMENT_BASED_UPGRADE,APP_MIGRATION,FINAL_ADJUSTMENTS

failed. See previous messages. Starting of the unit UPGRADE failed.

Connection to SAPJup could not be established, see following messages.

Could not connect to host XYZ on port 6240.

java.net.ConnectException: A remote host refused an attempted connect

operation. java.net.ConnectException: A remote host refused an attemptedconnect operation.

In which system do we have to check - Original system or shadow system?

The original system is down, so we are afraid to start the original

system in downtime phase. We have no idea where to check, please help.

We have checked the port on the host and the port is free, dont know why it cant connect.

Regards,

Mohan.

Hi Mohan,

At this step, J2EE server should be up and running. So, be sure the J2EE server started up and running. Then, continue the phase.

Hi Orkun,

the upgrade is in Downtime phase. We manually started the original system, the abap part is available now but as you pointed, the java part is not up. The error is - connection to Java Server Nodes not possible.

I usually check jcmon but it is not working here, i dont know why. When i check jcmon, there will be normally 3 processes (server0.....) and i can point out in which process, there is a problem. Now, i dont know where is the problem and how to go about. Any ideas??

Is it dual stack system? Could you check the log files under the paths, below;

ABAP stack:

<drive>:\usr\sap\<SID>\DVEBMGS<##>\work

Java stack:

<drive>:\usr\sap\<SID>\DVEBMGS<##>\j2ee\cluster\server0\log

<drive>:\usr\sap\<SID>\DVEBMGS<##>\j2ee\cluster\bootstrap

<drive>:\usr\sap\<SID>\DVEBMGS<##>\j2ee\cluster\dispatcher\log

Hi Orkun,

yes, it is a dual stack system.

I have checked under

<drive>:\usr\sap\<SID>\DVEBMGS<##>\j2ee\cluster\server0\log

<drive>:\usr\sap\<SID>\DVEBMGS<##>\j2ee\cluster\bootstrap

<drive>:\usr\sap\<SID>\DVEBMGS<##>\j2ee\cluster\dispatcher\log

very strange, i dont see any latest logs for today, all are in the previous days.

Under <drive>:\usr\sap\<SID>\DVEBMGS<##>\work, in dev_icm, i see the same error as given previously - connection to Java Server Nodes not possible (Java Startup Framework not initialized).

Could you check shadow instance trace files? try to start the j2ee instance and check the last 10 minute modified files, by the command below;

find . -mmin -10

Hi Orkun,

checked shadow instance logs but didnt find anything related to java. Very strange, very less information is recorded at the os level, cant find the exact reason for error. We have opened a ticket with sap and they are also searching for the root cause, no luck yet. Any more ideas??

Can you please check if port 6240 is occupied . This is the port JSPM listens to.

Use the command netstat -an |grep 6240

If its occupied check the process which is holding up the port .

hi Ratnajit,

the last line in my post already answers your question. The port is free.
