Our product line for DB2 Bind and Rebind Control and Administration:

Bind ImpactExpert for DB2 z/OS

The DB2 REBIND and BIND processes are intended to improve application performance, but sometimes a bind or rebind makes things worse. Bind ImpactExpert (BIX) provides automated and intelligent management of DB2 BINDs and REBINDs, assuring optimal application performance. BIX avoids surprises, even when you make dynamic SQL access path changes.

Access path changes can be caused by different reasons. Changed statistics, changes to the DB2 optimizer, as well as changed SQL in a new release of an application, can lead to changed access paths.

NEWS - What's new with BIX?
>> Package Stability Support
DB2 9 introduced a new feature that allows fallback to a prior access path based on a backup. BIX has a proactive approach that allows you to automatically predict access path changes before they happen, which is always preferred. In support of the PACKAGE STABILITY feature, BIX now insures that you can use PACKAGE STABILITY only if you really need it.

What's new?
In about 2% of all access path changes, automatic prediction of access path improvement or degradation is nearly impossible. For example, if the join sequence of a query changes, the resulting access path could be better or worse. BIX filters out such plans and packages to avoid any risk of performance degradation and secures them via the PACKAGE STABILITY enhancement of DB2.

How do you benefit?
Using the PACKAGE STABILITY feature is a reactive approach requiring additional directory space and increasing the REBIND time. Therefore, general usage is not recommended. If there are rare instances when access path prediction with BIX is not possible, combining BIX with the PACKAGE STABILITY feature is the perfect match.

Access path change control - areas of concern:

Where?

Why?

What?

Running BIX to precheck the results of a REBIND or a BIND is a simple and easy task. Let BIX analyze the BIND/REBIND commands in advance and decide on execution using rules combined with automation. However, many customers use BIX for much more complex scenarios than checking a single BIND or REBIND. Forecasting all access path changes of a DB2 version migration or driving your QA using BIX before even touching your production environment is not much more difficult. The new online interface of BIX now drives exactly the variety of processes that you want to do.

Whether you need to create a production baseline that is used for QA or doing analysis on dynamic SQL, let BIX guide you through the new Process Oriented Online Interface. BIX itself determines the required steps and directs you step by step.

How do you benefit? BIX assures company-wide standards and guides experts as well as newbies through a variety of tasks. Development processes can be streamlined easily while your production environment is secured from unwanted SQL or poorly performing access paths.
