startNodeManager.sh and startWeblogic.sh doesn't start to execute

Hi All,

Since last 2 days in one of my environment, I am not able to start my weblogic server. Sometimes when similar situation occur. i used to kill the process id of WL server (if i found process id by lsof). and then same way restarting of node manager. and it works. But this time something happening strange.

when i try to execute startNodeManager.sh or startWeblogic.sh , it doesnt even start executing. just it stands as blank after hitting enter.

Here is some logs which i found before this situation happened. As it shows heap size issue, is there any way to clear up heap? As i dont think i need to increase heap as this is working environment since long time.

main problem is I am not able to startNodeManager.sh and startWeblogic.sh,,

Any help/hint will helpout me a lot.

Environment Info

Weblogic 10
OS : Unix

Thanks in advance !!!
-Ronak

Hi Ronak,

As you can see you are getting outofmemory issue this means that your application/server needs more heap to run, hence do let us know what are the memory arguments have you given.

Also I would suggest you to have a look at the below link which would give a brief information about the out of memory issue, so do have a look it would surly help you.

Hi Ravish,

Thanks for your reply, I agree that i need to increase the heap by Xms and Xmx arguments.

But I am wondering that, even Node manager script execution is not getting start. even if its memory related issue then it should display the error messages on screen when execution starts, but instead it stick at blank screen, not even printing any info/error/warn messages. and this situation is for both startNodeManager.sh and startWeblogic.sh , please note its UNIX environment.

Please let me know if any suggestions.

Thanks,
Ronak.
 
It is sorta covered in the JavaRanch Style Guide.
