Tomcat在启动时抛出OutOfMemoryError

错误和跟踪：

在Windows 32位计算机上尝试启动Tomcat 7.0.28时，我看到以下

OutOfMemoryError

错误：

如果你需要更多的追踪，请告诉我

我尝试过的：

我曾试着去做，但没有成功。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

。该文件的全部内容包括：

SET CATALINA_OPTS="$CATALINA_OPTS -Xms512M -Xmx1024M"

---

重新启动服务器后，我看到了相同的错误。有什么帮助吗？谢谢。

您说过您使用Windows，但您已经创建了一个Unix shell脚本“.sh”。将其重命名为“.bat”。set命令应如下所示：

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