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. |
