Error in connecting plocal by OrientgraphFactory

[Shishya]

I get the following error on connecting plocal by graphFactory.

Code

        OrientGraphFactory factory = new OrientGraphFactory("plocal:/home/db/releases/orientdb-community-1.7-rc1/databases/test2","admin","admin").setupPool(1, 10);

        factory.getTx().getRawGraph().declareIntent(new OIntentMassiveInsert());

        OrientGraph graph = factory.getTx();

        System.out.println("Connected");

Hi,

But it seems JVM do not think so, (because of Caused by: java.lang.ClassNotFoundException: org.iq80.snappy.Snappy )

What is value of system property  "java.class.path" in your application ?

Hi,

I found that there is some other issue than plocal.

It works fine on local servers where WAL files can be accessed without sudo.

But on AWS, Java class needs to be run as sudo for direct read/write. But then Java class is not able to find the classes(all and any) when run as sudo either for remote or plocal.

Error is following when run with Sudo . The same runs fine(for remote) without sudo. Though this issue is unreleated now to Orientdb, but any help will be greatly appreciated.

Do you mean that you start JVM using root user privielges ?

For plocal, non-root users are not able to access WAL files, so have to use root

Hi,

It is not question of implementation but  file system permissions you use file system which does not allow to write access to the database folder, if we use permissions in database it was impossible to work with OrientDB on Windows because it does not have such permissions.

You should check your folder permissions.

Thanks Andrey

 But it is strange that remote is able to do so "www-data" but not others.
