If not present, resolves to 30 # the same directory that CATALINA_HOME points to. 31 # 32 # CATALINA_OUT (Optional) Full path to a file where stdout and stderr 33 # will be redirected. 34 # Default is $CATALINA_BASE/logs/catalina.out 35 # 36 # CATALINA_OPTS (Optional) Java runtime options used when the "start", 37 # "run" or "debug" command is executed. 38 # Include here and not in JAVA_OPTS all options, that should 39 # only be used by Tomcat itself, not by the stop process, 40 # the version command etc. 41 # Examples are heap size, GC logging, JMX ports etc. 42 # 43 # CATALINA_TMPDIR (Optional) Directory path location of temporary directory 44 # the JVM should use (java.io.tmpdir). Defaults to 45 # $CATALINA_BASE/temp. 46 # 47 # JAVA_HOME Must point at your Java Development Kit installation. 48 # Required to run the with the "debug" argument. 49 # 50 # JRE_HOME Must point at your Java Runtime installation. 51 # Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME 52 # are both set, JRE_HOME is used. 53 # 54 # JAVA_OPTS (Optional) Java runtime options used when any command 55 # is executed. 56 # Include here and not in CATALINA_OPTS all options, that 57 # should be used by Tomcat and also by the stop process, 58 # the version command etc. 59 # Most options should go into CATALINA_OPTS. 60 # 61 # JAVA_ENDORSED_DIRS (Optional) Lists of of colon separated directories 62 # containing some jars in order to allow replacement of APIs 63 # created outside of the JCP (i.e. DOM and SAX from W3C). 64 # It can also be used to update the XML parser implementation. 65 # Note that Java 9 no longer supports this feature. 66 # Defaults to $CATALINA_HOME/endorsed. 67 # 68 # JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start" 69 # command is executed. The default is "dt_socket". 70 # 71 # JPDA_ADDRESS (Optional) Java runtime options used when the "jpda start" 72 # command is executed. The default is localhost:8000. 73 # 74 # JPDA_SUSPEND (Optional) Java runtime options used when the "jpda start" 75 # command is executed. Specifies whether JVM should suspend 76 # execution immediately after startup. Default is "n". 77 # 78 # JPDA_OPTS (Optional) Java runtime options used when the "jpda start" 79 # command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS, 80 # and JPDA_SUSPEND are ignored. Thus, all required jpda 81 # options MUST be specified. The default is: 82 # 83 # -agentlib:jdwp=transport=$JPDA_TRANSPORT, 84 # address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND 85 # 86 # JSSE_OPTS (Optional) Java runtime options used to control the TLS 87 # implementation when JSSE is used. Default is: 88 # "-Djdk.tls.ephemeralDHKeySize=2048" 89 # 90 # CATALINA_PID (Optional) Path of the file which should contains the pid 91 # of the catalina startup java process, when start (fork) is 92 # used 93 # 94 # LOGGING_CONFIG (Optional) Override Tomcat's logging config file 95 # Example (all one line) 96 # LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties" 97 # 98 # LOGGING_MANAGER (Optional) Override Tomcat's logging manager 99 # Example (all one line) 100 # LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager" 101 # 102 # USE_NOHUP (Optional) If set to the string true the start command will 103 # use nohup so that the Tomcat process will ignore any hangup 104 # signals.
