OrientDB Server - server
The OrientDB Server is a Java application that manages database operations, retrieval and storage. The shell script server provides a convenient command-line interface to use in configuring and launching the OrientDB Server.
OrientDB provides a server.sh shell script for starting the server on Linux operating systems and a server.bat batch file for starting it on Windows.
Configuration Environmental Variables
OrientDB manages most of its configuration options through various XML configuration files. However, there are a handful of environmental variables that it utilizes when starting the Server. When the script runs, it check these variables to determine whether any value has been set on them. In the event that it finds none, it instead sets a sensible default value.
On Linux, you can set the environmental variable using the export command:
$ export ORIENTDB_HOME=/opt/orientdb/{{ book.currentVersion }}/
The following environmental variables are used by server.sh:
| Variable Name | Default | Description |
