Memory OrientDB/I可以在EC2 micro上运行的内存要求是什么？
我想在EC2微（免费层）实例上运行OrientDB。我找不到OrientDB的官方文档，其中给出了内存要求，但是我512MB应该可以。我正在运行一个EC2微实例，它有1GB内存。但是，当我尝试运行OrientDB时，会出现如下所示的JRE错误。我最初的想法是需要使用-xmx来增加jre内存，但我想应该是shell脚本来实现这一点。。是否有人在EC2微实例中成功运行OrientDB或遇到此问题Memory OrientDB/I可以在EC2 micro上运行的内存要求是什么？,memory,amazon-ec2,orientdb,Memory,Amazon Ec2,Orientdb,我想在EC2微（免费层）实例上运行OrientDB。我找不到OrientDB的官方文档，其中给出了内存要求，但是我512MB应该可以。我正在运行一个EC2微实例，它有1GB内存。但是，当我尝试运行OrientDB时，会出现如下所示的JRE错误。我最初的想法是需要使用-xmx来增加jre内存，但我想应该是shell脚本来实现这一点。。是否有人在EC2微实例中成功运行OrientDB或遇到此问题 OpenJDK 64-Bit Server VM warning: INFO: os::commit_m

Orient可以轻松地在512MB中运行，尽管您的性能和吞吐量不会那么高。在OrientDB 3.0.x中，可以使用环境变量
OrientDB\u OPTS\u MEMORYcd $ORIENTDB_HOME/bin
export ORIENTDB_OPTS_MEMORY="-Xmx512m"
./server.sh
$ORIENTDB_HOME另外，如果您查看
