无法启动OrientDB服务器

Question

我在服务器上安装了OrientDB 2.2.0，但无法运行server.sh脚本启动它。以前的版本在服务器上启动良好，当前版本正在我的笔记本上运行。服务器是一个来自数字海洋的液滴，Ubuntu 15.10 32位.我得到的错误在下面。

无效的最大直接内存大小：-XX:MaxDirectMemorySize=512g指定的大小超过最大可表示大小。错误:无法创建Java虚拟机。错误:已发生致命异常。程序将退出。

更新问题与-XX:MaxDirectMemorySize=512g有关。我把它改为-XX:MaxDirectMemorySize=512m，错误就消失了。现在的问题是服务器试图启动，但是给出了下面的消息：

Answer 1

(代表“任择议定书”张贴)。

现在一切都好了。我刚把-XX:MaxDirectMemorySize=512m改成了-XX:MaxDirectMemorySize=2g。

Answer 2

我想您有32位JVM。应该将此值设置为-XX:MaxDirectMemorySize=2g。
