The standard jre package does not include the necessary tools (ie. jps and jstack) for generating the jstack output.</P> <P>Requirements:</P> <P>1.) Obtain java sdk from <A href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">http://www.oracle.com/technetwork/java/javase/downloads/index.html</A> </P> <P>2.) Reconfigure db connect to use the sdk version of the jvm. </P> <P>For example, if you specify /usr/lib/jvm/jdk1.7.0_25 as the java home, ensure that there is a bin sub-directory which contains the java, jps, and jstack executables.</P> <P><IMG src="http://splunk-base.splunk.com//storage/Splunk_Manager_-_Splunk_5.0.4.jpg" alt="alt text" /></P> <P>While the issue is occurring: </P> <P>1.) Open a command prompt and cd into the $JAVA_HOME/bin directory</P> <P>2.) Run: jps -l (this will list running java processes) </P> <P>3.) Identify the process with the label com.splunk.bridge.JavaBridgeServer and copy the PID (number) </P> <P>4.) Run: jstack -l <PID> (where <PID> is replaced with the copied PID from step #3) </PID></PID></P> <P>5.) Copy the output and paste it into a text file for Support</P> Tue, 17 Sep 2013 22:08:44 GMT https://community.splunk.com/t5/Splunk-Dev/How-to-generate-java-jstack-of-the-db-connect-jbridge-process/m-p/65998#M910 splunkIT 2013-09-17T22:08:44Z
