21. From “Another DDS”
to OpenSplice DDS

22. Moving to OpenSplice DDS
There are at least two ways in which you could move to OpenSplice DDS
‣ Total Swap
Proprietary Information - Distribution without Expressed Written Permission is Prohibited.
‣ Your existing and future applications will run on OpenSplice DDS
‣ Incremental Swap
‣ You have legacy that will still need to run on other DDS implementation
‣ Next generation applications will run on OpenSplice DDS

23. Total Swap
Remove this code!
Technology Porting
‣ In this approach you port
existing code to OpenSplice DDS
Proprietary Information - Distribution without Expressed Written Permission is Prohibited.
‣ Since OpenSplice DDS is strictly
compliant with the OMG
standard, and requires zero
proprietary API for writing or
configuring DDS application,
you’ll simply need to remove
code
This example shows some OpenDDS-specifc API that have to be called in
order to configure the transport. Other DDS Implementation might require
the use of similar API. OpenSplice DDS does not require any API to configure
transports or anything else.

27. Migrating from other
Pub/Sub Technologies
© 2009, PrismTech. All Rights Reserved

28. Migration Tactics
Code Porting
‣ Porting leveraging equivalent functionalities is the approach most commonly taken
‣ This approach is typically not too hard as Pub/Sub APIs are often similar, and DDS
provides a sub-set of the functionalities typically found in other Pub/Sub systems
Proprietary Information - Distribution without Expressed Written Permission is Prohibited.
Business Logic Reuse
‣ With OpenSplice DDS the business logic reuse is facilitated by two technologies
‣ MDE PowerTools
‣ Data Local Reconstruction Layer
‣ The MDE approach requires to model the existing application and reuse the business
logic to implement the model
‣ The DLRL approach allows to completely hide the Pub/Sub aspect to the business
logic
