General¶

Component Start¶

Example start script

#!/bin/bash -e

if [ $# -ne 1 ]; then
  echo ""
  echo "  Usage: start.sh <component>"
  echo "    e.g. start.sh app-manager"
  echo ""

  exit 1
fi

component=$1

if [ -d ${component} ] ; then
  rm -rf ${component}/{logs,temp,work}/*
  rm -f logs/${component}.log*
fi

. `pwd`/${component}.env
`pwd`/bin/catalina.sh start

Component Stop¶

Example stop script

#!/bin/bash -e

if [ $# -ne 1 ]; then
  echo ""
  echo "  Usage: stop.sh <component>"
  echo "    e.g. stop.sh app-manager"
  echo ""

  exit 1
fi

component=$1

. `pwd`/${component}.env
`pwd`/bin/shutdown.sh

Component Restart¶

See Component Start and Component Stop!

Environment setting¶

Default values for Java memory allocations may be available using, for example, java -XX:+PrintFlagsFinal -version | grep 'PermSize'.

In the example scripts above reference is made to a local environment-setting file. An example of such file, e.g. app-manager.env, for Tomcat [1] use follows :

JAVA_HOME=/usr/java/current
CATALINA_HOME=/home/me/apps/tomcat/CATALINA_HOME
CATALINA_BASE=/home/me/apps/tomcat/vhosts/app-manager

# Xmx/Xms = JVM heap (max/initial). Object instance storage. Equal values == "fully committed" - avoids GC as initial expands to max.
# Xss     = Thread stack size. If you get a StackOverFlow exception, increase this value!
# -XX:PermSize -XX:MaxPermSize = Class files storage.
#CATALINA_OPTS="-Xms256m -Xmx256m -Xss256k -XX:PermSize=64m -XX:MaxPermSize=64m"

# Set in a 32-bit Win environment. Auto-enabled on 64-bit OSs
# JAVA_OPTS="-server"
JAVA_OPTS="-Dspring.profiles.active=app_manager_mysql"
