Informix Dynamic Server 11: Advanced Functionality for Modern Business

Chapter 4. Enhancements in high availability 121

4.5 Conclusion

IDS provides many new innovative features to support high availability of data.

The replication technology in earlier versions of IDS is widely used by clients and

meets their requirements. With the release of IDS 11, the replication technology

is enhanced further with new features, such as RSS, SDS, and CLR. What

makes it more interesting is that all the technologies can coexist and they work

together. It makes IDS a very powerful server to meet any challenging database

requirements. Permutations of HDR, ER, Storage Solution, SDS, RSS, and CLR

can provide many combinations to satisfy an extremely wide range of solutions

for database requirements. What makes the IDS solution unique is that all the

features are built within the server and they interact with each other. This

modular approach makes each feature simple to implement and use. The

interaction between the features enables you to solve a complex problem, and

that makes IDS a very powerful solution enabler. At the same time, the simplicity

of IDS is maintained, because any issues that might arise due to the combination

of technologies used can be resolved inside the server and thus can minimize

DBA activity and the overall cost of ownership.
