Hi Arjun,
With the new API the db creation is a bit different, programmatically it
would be something as follows:
OrientDB orient = new OrientDB("embedded:./",config);
orient.create("neurosys_orientdb_odb",ODatabaseType.MEMORY);
// and create a pool
ODatabasePool pool = new ODatabasePool(orient,"neurosys_orientdb_odb
","admin","admin",config);
// or open a connection directly
orient.open("neurosys_orientdb_odb","admin","admin",config);
So you need four parameters:
- the db path ("embedded:./" in this case, but if you only have in-memory
databases you can hard-wire it, as it will never be used)
- the actual db name (neurosys_orientdb_odb)
- the username
- the password
Probably you will have to do little changes to your application
accordingly, but it should not be too complex
I hope it helps
Thanks
Luigi
