Tomcat 在启动时抛出 OutOfMemoryError

Question

错误和跟踪:

尝试在 Windows 32 位计算机上启动 Tomcat 7.0.28 时，我看到以下 OutOfMemoryError 错误:

如果您需要更多跟踪信息，请告诉我。

我尝试过的:

我试着关注this solution至 this question about my OutOfMemoryError但都没有成功。更具体地说，遵循 catalina.sh...

中的指令

#   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.

...我在 CATALINA_BASE/bin 中创建了 setenv.sh。该文件的全部内容是:

SET CATALINA_OPTS="$CATALINA_OPTS -Xms512M -Xmx1024M"

重新启动服务器后，我看到了同样的错误。有什么帮助吗？谢谢。

您说您使用的是 Windows，但您创建了一个 Unix shell 脚本“.sh”。将其重命名为“.bat”。设置命令应如下所示:

SET "CATALINA_OPTS=%CATALINA_OPTS% -Xms512m -Xmx1g -XX:MaxPermSize=256m"
