Error 3105 : Non Local Drive Not Supported

Hi Jade Developers,

Recently preparing to move over to Jade 5.2 from 5.1.. After
upgrading an existing client, this error popped up due to the setup of the system.

The thing is the setup of the whole Jade system had been working
before while on 5.1. It's only after upgrading that it came up with
this error.

Basic setup is that : Jade's /bin is seperate from the /system [which
is stored on another server].

Any suggestions to overcome this error? Does that mean that Jade5.2
does not allow the /system to be away from the /bin? Was it something newly introduced to 5.2?

Also won't this have impact on a lot of installed systems whereby
there are emergency backup system where the /system is stored
seperately from the /bin?

Please advise and help.

Thanks in advance

L.C. Lim

I believe that the issue is that the database files MUST be on a local drive, and not on a network drive. This is to allow JADE to guarantee database integrity. If you have a network in the path of the database this is not possible.

You can certainly have the bin directory on a network fileshare, just that for a server, the database must be on a local drive.

Hope this helps..

Furthermore, they must be referenced with a non-unc path name.

We had a problem with this where the machine was \\jadeserver and using \\jadeserver\system didn't work. It had to be changed to C:\System.

From memory, its something to do with it going through the network layer.

Check out the technical paper on the Jade website called: Environmental Considerations for Deploying JADE. On page 5 it talks about Network File Systems: "From JADE 5.2 onwards locating Database transaction logs on network file systems is explicitly disallowed."

It's only the transaction log files that must be on the same computer that the Jade node is executing on. The actual database itself can be anywhere.

For performance reasons we insist that all of our sites have a bin directory for every computer that hosts a Jade node (client or
server).
