Usually I try to post at least a couple items a week, even when I'm out on vacation. However, last week I was on vacation on the Big Island of Hawaii (near Kona), and what can I say? Here's a picture of where I held office hours last week.
I will be at the Share conference in Anaheim this week. I will be doing a series of presentations on monitoring and performance management, and attending sessions. I'm sure I will come up with quite a few nuggets of relevant information for the blog, so please stay tuned.

I've posted several times on new features in OMEGAMON XE for DB2 V5.10. But, I think that's for good reason, there is quite a bit of new feature/function contained within this new release.
Probably one of the most interesting new features added to OMEGAMON XE For DB2 PE (important note - this is relevant for PE only, it's not in PM) is a feature called Extended Insight. Extended Insight provides something that many users ask for often; getting an analysis of DB2 distributed queries that will break out the host time versus the network time. Extended Insight helps to answer a key question: is the problem on the host and the SQL query, or is the problem in the network?
The nice thing about Extended Insight is it can be referenced interactively within the Tivoli Enterprise Portal. When you are in a thread view you can drill down and get the relevant Extended Insight performance stats. In the screen shot I show here, you can see an example of the navigation. Another interesting thing about Extended Insight is it allows OMEGAMON DB2 to provide information that integrates nicely with ITCAM displays, and provides drill down detail of SQL level activity within ITCAM.
Again, please note that Extended Insight is only available with OMEGAMON XE For DB2 Performance Expert (PE), and is not in OMEGAMON For DB2 PM. So if you are a PM customer and want the feature, you may need to upgrade to PE. If in doubt, contact your IBM rep. I'm sure they will be happy to help you out.

The cost of Near Term History collection in OMEGAMON can vary. It has the potential to be costly primarily because it has the potential to collect and store a considerable amount of data. In some shops it may be as much as millions of records of information per day.
What V5.10 provides is support for zIIP processor utilization by the tasks that write Near term History. The OMEGAMON DB2 zIIP support requires no special configuration options for the zIIP processor, and requires no special configuration or setup in WLM. Essentially what happens is, if a zIIP is available, OMEGAMON DB2 has the option of using, if appropriate.
zIIP support is a good way to offload some of the cost of DB2 historical data collection.

DB2 Version 10 offers quite a few new monitoring and metric capabilities. DB2 10 improves the support for monitoring and managing both static and dynamic SQL. A unique statement execution identifier (that I mentioned in a prior post) is introduced. Statement type and statement execution identifier are externalized that can be used to correlate statement execution on the server with the client application.
Here is an example of the kind of information you can now get in OMEGAMOn DB2 V5.10. Note that the information looks similar to what you could get before for dynamic SQL, but now we can get similar information for Static SQL. Look closely at the example, and you will see what I mean.

DB2 Version 10, like most new DB2 versions, provides more traces, more trace granularity and detail, and more collection/analysis options. This includes new trace IFCIDs, and more information added to existing IFCIDs. Some of the most interesting stuff revolves the notion of a statement ID. Statement ID is a unique counter used to identify a statement, and its usage, across a DB2 system. It allows for more granularity of performance information at the statement level.
OMEGAMON DB2 V5.10 provides support for statement ID information in several ways, including both the Tivoli Portal and Classic 3270 interface. This information can be shown for both dynamic as well as for static SQL calls. It looks like very useful information, and I plan to do some additional posts on this, and in general on OMEGAMON DB2 V5.10.
