Tomcat 6堆大小 - 这是正确的吗？ [英] Tomcat 6 Heap Size - Is this correct?

问题描述

我在Red Hat盒子上运行多个tomcats，我想为每个tomcats配置单独的堆大小（某些实例使用更多内存）。

I am running multiple tomcats on a Red Hat box and I would like to configure separate heap size for each of them (some instances use more memory).

可以我将堆大小min / max bt设置为catalina.sh文件中的以下内容：

Can I set the heap size min/max bt entering the following into the catalina.sh file:

CATALINA_OPTS = - Xms64m -Xmx256m

CATALINA_OPTS="-Xms64m -Xmx256m"

我需要添加'导出'吗？即导出CATALINA_OPTS = - Xms64m -Xmx256m

Do I need add 'export'? i.e. export CATALINA_OPTS="-Xms64m -Xmx256m"

推荐答案

最佳做法是将环境变量的设置放在名为<的文件中bin文件夹中code> setenv.sh / .bat 。

Best practice is to put the setting of environment variables in a file named setenv.sh/.bat in the bin folder.

catalina.sh 脚本具有调用此脚本的逻辑（如果存在）。

The catalina.sh script has logic to call into this script, if it exists.

之所以如此建议是因为它使您的安装所需的环境变量设置为可移植：您可以轻松地将 setenv.sh 复制到其他Tomcat安装，您可以将Tomcat升级到更新版本（这可能会覆盖 catalina.sh ）但仍然有你现有的 setenv.sh 。

The reason why this is recommended is because it makes setting of environment variables needed for your installation portable: you can easily copy setenv.sh to other Tomcat installations, you can upgrade Tomcat to a newer version (which might overwrite catalina.sh) but still have your existing setenv.sh.

如何在 setenv.sh 中设置堆大小的示例：

An example on how to set the heap size inside setenv.sh:

export JAVA_OPTS='-Xmx784M`
