Greetings! We have used CentOS 7 I believe, but we never use the package manager version of Tomcat. That should not matter for this issue, however. I think the key here is that the tds.content.root.path Java System Property isn't being passed into the JAVA_OPTS variable, and so the TDS cannot find it. You currently have that property stored in an environmental variable called CONTENT_ROOT. You could do one of two things. 1) Reference $CONTENT_ROOT when setting JAVA_OPTS: JAVA_OPTS="$JAVA_OPTS $CONTENT_ROOT -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true" 2) Skip using the CONTENT_ROOT variable and directly add the Java System Property to the JAVA_OPTS variable: JAVA_OPTS="$JAVA_OPTS -Dtds.content.root.path=/var/lib/tomcats/ops/content/ -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true" Second, I think you will need to explicitly export the JAVA_OPTS variable so that the CATALINA_HOME/bin/catalina.sh has access to it. So, make sure to add export $JAVA_OPTS to the end of your setenv.sh file. Overall, your setenv.sh file might look something like: -- #!/bin/bash CONTENT_ROOT="-Dtds.content.root.path=/var/lib/tomcats/ops/content/" JAVA_OPTS="$JAVA_OPTS $CONTENT_ROOT -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true" export JAVA_OPTS -- My guess is that you'd also want to tweak the memory allocated to the JVM here as well buy adding the desired -Xmx option to the JAVA_OPTS variable as well.
