Java运行时异常：无法创建锁管理器

Question

Hello when I run a script as root on unix shell it works, for example:

sh -x /opt/auto/wso2is/bin/wso2server.sh 

However when I run it as a non root user I get the following error:

java.lang.reflect.InvocationTargetException

    ... 6 more

What is causing this?

I have the following environment variables declared:

JRE_HOME=/usr/java/jre1.7.0_51 

PATH=/sbin:/usr/sbin:/usr/local/sbin:/root/bin:/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/kde3/bin:/usr/lib/java/jre/bin:/usr/local/bin

JAVA_BINDIR=/usr/java/jdk1.7.0_51/bin

JAVA_HOME=/usr/java/jdk1.7.0_51

JDK_HOME=/usr/java/jdk1.7.0_51 

JAVA_ROOT=/usr/java/jdk1.7.0_51

According to http://www-01.ibm.com/support/docview.wss?uid=swg21600112 , I don't have correct permissions for a folder but how am I meant to know which one?

I found a workaround that might be able to give you a hint on what are the files have been changed on the permission due to previous startup using root user account.

You may do a du -skh /opt/auto/ using a non-root user account. You will get permission denied when it attempt to check on the files/folders that is belongs to the root user. Then you should execute chown -R "<non-root-user>:<non-root-user> <file/folder> on those file/folder.

Once you have changed the ownership of the files/folder, please try to start it up again (by executing /opt/auto/wso2is/bin/wso2server.sh). You should be able to get wso2carbon log printed. Study the log again and make further amendment on the file/folders which still having permission error.
