OrientDB安装Raspberry Pi的问题
[英]OrientDB installation of Raspberry Pi issues
问题描述
I'm hitting some snags getting OrientDB installed on my Raspberry Pi and ran out of ideas from Googling. 
我遇到了一些麻烦，在Raspberry Pi上安装了OrientDB，但用完了Googling的想法。 I tried adding -Dmemory.useUnsafe=false -Dstorage.compressionMethod=gzip to the end of the last line of the /bin/server.sh but that didn't seem to help. 我尝试将-Dmemory.useUnsafe=false -Dstorage.compressionMethod=gzip添加到-Dmemory.useUnsafe=false -Dstorage.compressionMethod=gzip最后一行的末尾，但这似乎无济于事。
The server starts and I can access it over HTTP but the JVM crashes when I try to create a database or connect to the default database. 服务器启动，我可以通过HTTP访问它，但是当我尝试创建数据库或连接到默认数据库时，JVM崩溃。 Any ideas? 有任何想法吗？

Raspberry Pi and OrientDB ... could not resist trying it out :) Raspberry Pi和OrientDB ...无法抗拒尝试:)
For your information: 供你参考：
- Using Raspberry Pi model B (512MB) 使用Raspberry Pi模型B（512MB）
- Using Raspbian 7.6 (with latest patches as of 2014-11-28) 使用Raspbian 7.6（具有2014年11月28日的最新补丁）
- Using Oracle Java 8 SE for ARM update 6 (so not the version from the Raspbian repo!) 使用Oracle Java 8 SE进行ARM 更新6 （因此不能使用Raspbian存储库中的版本！）
- Using OrientDB 2.0-M3 使用OrientDB 2.0-M3
- Set
MAXHEAP=-Xmx128minserver.sh在server.sh设置MAXHEAP=-Xmx128m
With this configuration i am able to create / query / modify a database via HTTP without problems. 通过这种配置，我能够通过HTTP创建/查询/修改数据库，而不会出现问题。 OrientDB complains about the shortage of memory, but that is all: OrientDB抱怨内存不足，仅此而已：
WARNING No enough physical memory available: 437MB (heap=123MB).
