How to set CATALINA_OPTS in Tomcat’s setenv.sh

How to set CATALINA_OPTS in Tomcat’s setenv.sh

How to set CATALINA_OPTS for the JVM used by Tomcat.

Write CATALINA_OPTS in $CATALINA_BASE/bin/setenv.sh or $CATALINA_HOME/bin/setenv.sh.

In my environment, it was found in the following.

/opt/tomcat/bin/setenv.sh

In catalina.sh, setenv.sh is loaded if present.

catalina.sh

if [ -r "$CATALINA_BASE/bin/setenv.sh" ]; then
  . "$CATALINA_BASE/bin/setenv.sh"
elif [ -r "$CATALINA_HOME/bin/setenv.sh" ]; then
  . "$CATALINA_HOME/bin/setenv.sh"
fi

Here is an example of setting system properties with the -D option to the JVM.

setenv.sh

CATALINA_OPTS=" \
-Dbtm.root=$CATALINA_HOME \
-Dbitronix.tm.journal.disk.logPart1Filename=/opt/tomcat/logs/btm1.log \
-Dbitronix.tm.journal.disk.logPart2Filename=/opt/tomcat/logs/btm2.log \
-DPARAM1=true \
-DPARAM2=1 \
-DYAHOO_HOME=https://www.yahoo.co.jp \
"

setenv.sh does not have to be a shell; setting variables in catalina.sh should be avoided and should be in setenv.sh.
