Issue/Introduction

Spectrum Tomcat does not start after changing the default tomcat log location on the OneClick server

Environment

DX NetOps Spectrum all releases

Cause

The tomcat log (catalina.out on linux and stdout.log on windows) is not in the default location but has been moved to a new custom location.

Default location is $SPECROOT/tomcat/logs

Resolution

In order for the tomcat log to be placed in a custom location, the following changes must be done:

1. Change the following in the $SPECROOT/tomcat/bin/catalina.sh file  on Linux (after backing up the original file) or under Windows, edit the oneclickservice.conf file. For the following example on Linux, assume the custom location is changed to /var/log/tomcat/catalina.out

So on Line 223, change:
   
   JAVA_OPTS="-DOneClick -server -Xmx10000M -XX:+HeapDumpOnOutOfMemoryError -Djava.awt.headless=true -Djavax.net.ssl.trustStore=$SPECROOT/custom/keystore/cacerts -Dfile.encoding=UTF-8 -Dcom.sun.management.jmxremote -Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true" 

to
   
   JAVA_OPTS="-DOneClick -server -Xmx10000M -XX:+HeapDumpOnOutOfMemoryError -Djava.awt.headless=true -Djavax.net.ssl.trustStore=$SPECROOT/custom/keystore/cacerts -Dfile.encoding=UTF-8 -Dcom.sun.management.jmxremote -Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true -DCATALINA_OUT=/var/log/tomcat/catalina.out"


2. So that the custom location is passed to the CATALINA_OUT on Line 232, change
   
   CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
   
   Must be changed to the custom location, for example:
   
   CATALINA_OUT="/var/log/tomcat/catalina.out"
   
   
3. Restart OneClick Tomcat
