Hi Ken,
openClovis ASP has support for transaction mechanism. Please refer to openClovis_ReferenceGuide-2.2.pdf.
Section 3.52-3.54 explains the details.

The following link takes you to the Header files mentioning the supported APIs.
http://www.openclovis.org/filebrowser/OpenClovis_Release2.2/src/SISP/components/txn/include
More specifically to your questions ASP supports clubbing multiple jobs into a single transaction.

HTH,
Hari

Hi Hari,
As you know,multiple jobs can be included in a single
transaction. I wonder what a job stand for? How a job and
a transaction is generated? According to OpenClovis User Guide,
COR is a distributed database, by default, COR objects are replicated
on two controller card. Is transaction mechanism just used to make
sure that multiple replicas of the same object are consistent?

Can i submit modification of multiple configuration objects
(not just multiple replicas of the same object)
at the same time?

Thanks
ken

Hi Ken,
You can configure multiple objects(of different type) in a single transaction.
Please look at clCorObjectAttributeSet, clCorTxnSessionCommit APIs and thier usage to get a better idea of how to use transacion semantics supported by COR
