(Martin) 98% of our studio audience learned something!Cristian provided tips and insight into application and system performance for DB2 11.

(Dave Beulke) As I talked about last week, and the week before, tuning application and database performance by optimizing database I/O performance involves many different components. When I left off last week I referenced that the physical I/O path components need to be tracked back through the FIC

(Martin Smithson and Anna Pendrich) Combining IBM Integration Bus (IIB) with WebSphere Service Registry and Repository (WSRR) lets you dynamically retrieve service metadata from WSRR and use it to modify message flow behavior at runtime.

(Craig S. Mullins) I get the chance to talk to a lot of DBAs in my line of work, and that sometimes gets me thinking about the things that DBAs spend time on and what they feel are the most important aspects of their job.

(Walid Rjaibi) In the four previous parts, we have covered the cloud computing models, the shared responsibility security model, the responsibilities of the cloud service provider, and those of the client. Today, we cover IBM BLU Acceleration for Cloud as a data security in the cloud use case. So, l

(A.Nariovich) When it comes to deploying a piece of infrastructure, clients have a wide selection of products. Some of the clients make decisions based on their previous experience, skills and research. Others take time and effort to evaluate a subset of products in order to select the best one base

(Daniel L. Luksetich) Concurrency is a critical performance aspect of any database application. While there are many options available to improve it, one of the more recent features that has quietly made its way into DB2 for LUW and z/OS is concurrent access resolution.

(Mark Gillis) Part 1 was a basic illustration of how INGEST can be used to provide a high-availability data replication mechanism without employing expensive and complicated ETL. In Part 2, I’m going to try and explore a few more complicated options: enriching or extending the data as it is ingested

(Paul Anderson) Informix provides the functionality to restore a single table or a subset of a table to a point in time or to the last archive. This functionality was originally released in IDS v10 and is provided through the archecker software which is included with the engine.

(Craig S. Mullins) Check constraints are a very useful, though somewhat underutilized feature of DB2. Check constraints enable enhanced data integrity without requiring procedural logic (such as in stored procedures and triggers). Let’s examine the basics of table check constraints.
