如何在Apache Tomcat 6中添加jvm（Java虚拟机）选项？
Tomcat中是否有管理控制台？我尝试使用http://localhost:8080/admin，但无法获取任何内容。
我想添加以下jvm选项：
-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5
正如Bhavik Shah所说，您可以在JAVA_OPTS中完成此操作，但根据catalina.sh的建议方式是使用CATALINA_OPTS:
# CATALINA_OPTS (Optional) Java runtime options used when the "start",
# "run" or "debug" command is executed.
# Include here and not in JAVA_OPTS all options, that should
# only be used by Tomcat itself, not by the stop process,
# the version command etc.
# Examples are heap size, GC logging, JMX ports etc.
# JAVA_OPTS (Optional) Java runtime options used when any command
# is executed.
# Include here and not in CATALINA_OPTS all options, that
# should be used by Tomcat and also by the stop process,
# the version command etc.
# Most options should go into CATALINA_OPTS.
将其设置在[path to tomcat]/bin/catalina.sh的JAVA_OPTS变量中。在Windows下，有一个控制台可以设置它，或者您可以使用catalina.bat。
JAVA_OPTS=-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5
检查catalina.sh文件（对于Windows，请使用下面提到的所有内容的.bat版本）
# Do not set the variables in this script. Instead put them into a script
# setenv.sh in CATALINA_BASE/bin to keep your customizations separate.
还有这个
# CATALINA_OPTS (Optional) Java runtime options used when the "start",
# "run" or "debug" command is executed.
# Include here and not in JAVA_OPTS all options, that should
# only be used by Tomcat itself, not by the stop process,
# the version command etc.
# Examples are heap size, GC logging, JMX ports etc
在CATALINA_BASE/bin目录下创建一个setenv.sh文件（与catalina.sh位于同一目录）。编辑该文件，并将参数设置为CATALINA_OPTS。
例如，如果您想更改堆大小，文件应如下所示：
CATALINA_OPTS=-Xmx512m
如果你正在使用Windows，那么setenv.bat就是你需要的。
set CATALINA_OPTS=-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5
要后来清除添加的选项，只需删除setenv.bat/sh文件。
要实现此功能，您需要运行Tomcat发行版中“bin”目录下的“tomcat6w”应用程序。例如，对于Windows，默认路径为“C:\Program Files\Apache Software Foundation\Tomcat 6.0\bin\tomcat6w.exe”。 “tomcat6w”应用程序会启动一个GUI界面。如果选择“Java”选项卡，您可以输入所有Java选项。
还可以通过命令行传递JVM选项给Tomcat。为此，您需要使用以下命令：
<tomcatexecutable> //US//<tomcatservicename> ++JvmOptions="<JVMoptions>"
"tomcatexecutable"指的是您的Tomcat应用程序，"tomcatservicename"是您正在使用的Tomcat服务名称，而"JVMoptions"则是您的JVM选项。例如：
"tomcat6.exe" //US//tomcat6 ++JvmOptions="-XX:MaxPermSize=128m"
`<#
-Options:"-DRESOURCE_LOCATION=C:\data\"
This one is working for Windows Service.
#>
Function AppendTomcatJavaOptions1([string]$TomcatBin, [string]$Options)
{
# In this case we're taking advantage of the fact that we named the service the same as the /bin/tomcat.exe
# but if your service name is different, you may need to modify this.
$cmd = """$TomcatBin\$($TomcatServiceName).exe"" //US//$TomcatServiceName ++JvmOptions=$Options"
Write-Host "Appending Java Options via Service option: $cmd"
cmd.exe /C "$cmd"
}` - m1m1k
setenv.bat文件，并添加以下内容：echo "hello im starting setenv"
set CATALINA_OPTS=-DNLP.home=${NLP.home} -Dhostname=${hostname}
-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5
export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxPermSize=256m"（这将增加最大永久代大小）。 - whla
