I am reading the document at the URL http://db.apache.org/ojb/docu/howtos/howto-work-with-clustering.html ...but I have some doubts about what to do for reducing the impact on the project.
My needs are the following ones:
* I am using Microsoft SQL Server 2000.
* I am using tables with integer IDs and I'd like not to change the
PK definition in the tables.
* I'd like not to modify the tables with additional columns for
optimistic lock.The reason of my requests of not changing the tables is their number: more than 300! You understand it could be a very heavy work to inform every developer that he/she has to change his/her table definitions. The same applies to the class-descriptor items in the repository: I'd like not to alter them... even if it could be more acceptable than modifying the DB.
The ideal solution would be to work only on the connection descriptor, the OJB.properties file and to keep the tables and their descriptors as they are. Is it possible to preserve all this requirements? Can you suggest the adequate Sequence Manager and other settings?
Thanks in advance... bye,
Marcello
