SAP is not coming up after EP installation

[Former Member]

Hi Experts,

We are facing problem while trying to start SAP after EP installation.

Everytime we are trying to start EP the file system /usr/sap/QP1

and /tmp getting filled up. Everytime it is generating core dump files

(like core.20100309.115811.290824.0001.dmp,

core.20100309.115827.290824.0005.dmp,

core.20100309.104638.323622.0009.dmp)

under /usr/sap/QP1/JC00/j2ee/cluster/server0 and /tmp. How to resolve

this problem?

Regards,

The .dmp files are generated if the system is IBM platform and is configured to generate the heapdumps in MAT recognizable format. These dumps are created on outofmemory crash.

Since its a new system most likely the JVM settings are not configured correctly.

Please refer to the note 723909 and OS specific notes within that suggest the correct settings.

If you think your JVM settings are configured as per the recommendations and still the system is crashing with outofmemory then you can download the MAT Tool from www.eclipse.org/mat and install it on one of your windows machines where you have atleast 4G RAM. Please analyze the .dmp using the MAT tool. Leak Suspect report in the same will point to the culprit if any application or bug is causing the outofmemory due to leak. Open an SAP message in relevant component to resolve that if that's the case.

I already applied this note and 723909 but no luck.

Some hints...

You should check your virtual memory on your operating system:

How much is free?

Is there enough for the Java stack of EP to start?

Do you have enough pagefile if you don't have much RAM?

You can adjust the EP java stack parameters in ConfigTool if needed.

Until enough free virtual memory is found, the Java stack will not start.

Check you are getting out of memory error. Check SAP note 709140 for parameter settings.

Thanks

You may want to check dev_bootrap, dev_jcontrol, dev_server0 for more details. These files are available in work directory.

[Former Member]

Your system is generating core dump.Please check the oracle alert log file as well as trace file for the same.Kindly check if your database is in consistent state.

also please check the DB connectivity with command R3trans -d.If needed take a restart of your DB after resolving your DB issue in case there is any.

Thanks..

Hi,

>How to resolve this problem?

Maybe by explaining clearly what you are doing ?

What do you call SAP ? Is it EP or an other SAP software on the same physical server ?

Hello Subhadip,

Can you please post dev_server0 file details.
