无法启动 OrientDB 服务器
Can't start OrientDB Server
我在我的服务器上安装了 OrientDB 2.2.0 但无法启动它 运行 server.sh 脚本。以前的版本在服务器上运行良好，当前版本在我的笔记本上是 运行。服务器是来自 Ubuntu 15.10 32 位的 Digital Ocean 的 droplet。我得到的错误如下。
Invalid maximum direct memory size: -XX:MaxDirectMemorySize=512g The
specified size exceeds the maximum representable size. Error: Could
not create the Java Virtual Machine. Error: A fatal exception has
occurred. Program will exit.
更新
问题在于 -XX:MaxDirectMemorySize=512g。我将其更改为 -XX:MaxDirectMemorySize=512m 并且错误消失了。现在的问题是服务器尝试启动但给我以下消息：

我想你有 32 位 JVM。您应该将此值设置为 -XX:MaxDirectMemorySize=2g .
(代表OP发表).
现在一切正常。我刚刚将 -XX:MaxDirectMemorySize=512m 更改为 -XX:MaxDirectMemorySize=2g。
