isAuthorized() 异常：无法关闭 ID 为 0 的文件，因为它仍在使用中
isAuthorized() Exception: Can not close file with id 0 because it is still in use
我升级 Orientdb 从 2.0.16 到 2.2.4.
在 2.0.16 中一切正常（数据库 运行 和浏览器登录正常）。但现在不是在 2.2.4 中。我在日志中得到了这个：
2016-07-10 20:59:41:942 WARNI {db=OSystem} MBean with name
com.orientechnologies.orient.core.storage.impl.local.paginated.atomicoperations:id=1899654914,name="OSystem",type=OAtomicOperationsMangerMXBean
has already registered. Probably your system was not shutdown
correctly or you have several running applications which use OrientDB
engine inside [OAtomicOperationsManager] 2016-07-10 20:59:41:944 SEVER
isAuthorized() Exception: Can not close file with id 0 because it is
still in use
DB name="OSystem" [OSystemUserAuthenticator]
所以我尝试在我的 Windows 机器上本地 运行 它。我刚刚下载了整个文件夹，然后开始 server.bat。而且它没有任何错误。
那么为什么在 Ubuntu 上会抛出该错误？为什么它与 Windows 机器上的同一个文件夹一起工作？除了内存设置外，我没有更改任何内容，在 Ubuntu 机器上需要降低内存设置。
当我今天开始 server.sh 时...
我得到这个：
sh /home/ubuntu/orientdb/bin/server.sh

来到这里遇到同样的问题，可以通过卸载 java9 并安装 java8 来修复它。这是我遵循的步骤。
sudo apt-get remove openjdk-9-jdk
sudo apt-get autoremove
sudo apt-get install openjdk-8-jdk
希望对您有所帮助。
我得到了 here 的帮助。所以解决方案非常简单。只需在 server.sh:
中设置一些设置
if [ -z "$ORIENTDB_OPTS_MEMORY" ] ; then
ORIENTDB_OPTS_MEMORY="-Xms64m -Xmx128m"
fi
if [ -z "$JAVA_OPTS_SCRIPT" ] ; then
JAVA_OPTS_SCRIPT="-Djna.nosys=true -XX:+HeapDumpOnOutOfMemoryError -XX:MaxDirectMemorySize=200g -Djava.awt.headless=true -Dfile.encoding=UTF8 -Drhino.opt.level=9"
fi
# ORIENTDB SETTINGS LIKE DISKCACHE, ETC
if [ -z "$ORIENTDB_SETTINGS" ]; then
ORIENTDB_SETTINGS="-Dstorage.diskCache.bufferSize=128 -Dmemory.chunk.size=33554432"
fi

现在我尝试将 JDK9 降级为 JDK8
已降级为 JDK 8...

来到这里遇到同样的问题，可以通过卸载 java9 并安装 java8 来修复它。这是我遵循的步骤。
sudo apt-get remove openjdk-9-jdk
sudo apt-get autoremove
sudo apt-get install openjdk-8-jdk
希望对您有所帮助。
我得到了 here 的帮助。所以解决方案非常简单。只需在 server.sh:
if [ -z "$ORIENTDB_OPTS_MEMORY" ] ; then
ORIENTDB_OPTS_MEMORY="-Xms64m -Xmx128m"
fi
if [ -z "$JAVA_OPTS_SCRIPT" ] ; then
JAVA_OPTS_SCRIPT="-Djna.nosys=true -XX:+HeapDumpOnOutOfMemoryError -XX:MaxDirectMemorySize=200g -Djava.awt.headless=true -Dfile.encoding=UTF8 -Drhino.opt.level=9"
fi
# ORIENTDB SETTINGS LIKE DISKCACHE, ETC
if [ -z "$ORIENTDB_SETTINGS" ]; then
ORIENTDB_SETTINGS="-Dstorage.diskCache.bufferSize=128 -Dmemory.chunk.size=33554432"
fi
