Hi All,

I have a client who wishes to run to independent Jade systems and transfer limited amounts of data between them. Does anyone out there have a technique to transfer objects between two jade systems?

Cheers,

I was hoping somebody would come up with an answer to this as have a similar problem.

The options I'm considering at the moment include
1. Copying the dat file(s) of the required classes from one system to another. This requires that the schema structures are symmetric in order to preserve the Class oids. It also requires resetting the timestamps of the map files which presumably can be done using the db util in batch mode. 2. Jade consultants have an XML import/export utility which can work with a bunch of Classes and overcomes oid problems. Apparently it can cope with any references between instances being exported. Trouble is, they haven't released it.
3. Defining relational views over jade classes so ODBC can be used.
4. Writing own methods to/from flat files for each class

cheers
Tony

This is the approach I will use if I end up having to do it myself. The oid problem shouldn't be that much of an issue....depends if you have transitive closure on the objects being transmitted or not. (ie, they only reference each other and not any non-transmitted objects).

The XML tools are included in the current BaseSchema release (12 February, 2001), however we're still in the process of documenting them. As you can probably imagine, it's not a trivial task.

Yes, but for a price, which is currently set at $10K. If you're interested, contact your JADE Sales Rep, or if you don't have one, contact Lucy Williams here at JADE.
