[orientdb] In 3.0.0 unlike ODatabaseDocumentTx , OrientDB constructor throwing exception for in memory DB

[arjun dhar]

Hi,

*Summary*
Am on OrientDB 3.0.0 ; and am trying to avoid the use of Depreicated API
like: ODatabaseDocumentTx
However, when I replace it with
com.orientechnologies.orient.core.db.OrientDB ; for the same configs that
otherwise work fine it blows up.

Details below...

*Configuration*
```
odb.url=memory:neurosys_orientdb_odb
odb.username=admin
odb.password=admin
odb.maxPartitionSize=2
odb.maxPoolSize=10
```

*Spring Configs *using ODatabaseDocumentTx that work
```
<bean id="*dataSourceOdb*"
class="com.orientechnologies.orient.core.db.document.ODatabaseDocumentTx"
init-method="create">
<constructor-arg value = "${odb.url}"/>
</bean>

<bean id="connectionPoolDataSourceOdb"
class="com.orientechnologies.orient.core.db.OPartitionedDatabasePool">
<constructor-arg value = "${odb.url}" index="0"/>
<constructor-arg value = "${odb.username}" index="1"/>
<constructor-arg value = "${odb.password}" index="2"/>
<constructor-arg value = "${odb.maxPartitionSize}" index="3"/>
<constructor-arg value = "${odb.maxPoolSize}" index="4"/>
</bean>
```

*Spring Configs *using com.orientechnologies.orient.core.db.OrientDB that
does *not *work
Simply replacing the `*dataSourceOdb*` bean.
```
<bean id="dataSourceOdbNew"
class="com.orientechnologies.orient.core.db.OrientDB">
<constructor-arg value = "${odb.url}"/>
<constructor-arg value = "${odb.username}" />
<constructor-arg value = "${odb.password}" />
<constructor-arg><null /></constructor-arg>
</bean>
```

*Exception thrown*
```

at
com.orientechnologies.orient.core.db.OrientDBEmbedded.open(OrientDBEmbedded.java:131)

```

*Possible cause*
Looks like the path is getting messed up and assuming unix convention path
even for an in memory DB. Am on windows, but I dont see why that anyway
matters for an in-memory DB, plus it works with the deprecated one. *So I
assume this to be a bug, if not please let me know what Im missing.*

thanks,
Arjun

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
