db4o's is an embedded database which usually runs in process. Nevertheless db4o also supports a client server setup. There's no ready to use db4o server, instead you embedded the db4o server in a regular application. This gives you full how you want to run the db4o server.
In order to use the db4o client server mode you need to include the db4o-X.XX-cs-javaC.jar if your not using the db4o-X.XX-all-javaX.jarDb4objects.Db4o.CS.dll-assembly in your project. See "Dependency Overview"
You start the server by creating a object server instance with the client server factory. Pass the database file path and the port to the factory. After that you need to specify a user-name and password which clients can use to login to this server. You can add multiple users by calling the grant access method multiple times.
ObjectServer server = Db4oClientServer.openServer("database.db4o",8080); try{ server.grantAccess("user","password"); // Let the server run. letServerRun(); } finally { server.close(); }
After the server is up an running you can connect to it. Pass the URL, port, user name and password to the client server factory. This will return a client object container. After that the container is ready to use.
final ObjectContainer container = Db4oClientServer.openClient("localhost", 8080, "user", "password"); try{ // Your operations }finally { container.close(); }
