Abstract

Database optimization tasks must be continually

performed to help improve performance, scalability,

platform support, standards compliance and usability

while simultaneously reducing costs and risk. Have

difficulty building, testing and deploying new DB2®

database functions and performance? Learn more about

a number of new enhancements for your DB2 database

management tools from CA Technologies.

The Challenge

Methods Adjusts SQL statements, runs reorg utility, tunes databases, etc.

Challenge Finding best applications to tune

Data Performance metrics for executions of SQL statements, packages and plans (Version 1 uses data from CA Detector® for DB2 for z/OS)

Limitations Performance metrics tell you where you are, but fall short: How you got here (is today’s behavior “normal”?) Where you are going (is performance getting better or worse?) Where the greatest tuning potential is (which applications account for the greatest

increases in resource usage? ) Does is matter if a transaction is using 15 GETP as opposed to 10 one month ago ?

Maybe—what if it executes 20 million times/daily and can you “normalize dynamic statements?

DBAs struggle to identify, tune & minimize elapsed time, CPU and Getpages.


A Better Outcome

Monitor trends, identify potential problems before they occur.

Manually determine, set and adjust thresholds for monitoring applications.

Automatically determine what is “normal.”

Less time needed:

– Reviewing false or short-term “spike” alerts / event notifications (as opposed to sustained deviations)

– Defining/maintaining thresholds

Proactively monitor application performance or rely on user complaints.

Need to Use IDAA to Improve Application Performance

Impact on DB2/Customer– IBM® Optim Data Studio is difficult to use to administer and manage

IDAA.

– IBM Optim Data Studio is not on the mainframe.

Solution– Use CA RC/Query® to drastically simplify management of your objects

on the DB2 Analytics Accelerator.

IDAA Table level functions are available to

Define, Alter, Remove, Load, etc.

Familiar Interface

RC/Q Accelerator Table list report provides table level

admin of your IDAA

Load DB2 Table to IDAA RC/Q ALOAD CMND Load range of

partitions or entire Table

Uses IDAA Loader utility

Ability to Start, Stop, Display and PING

Accelerator


CA RC/Query® for DB2 for z/OS

Easily visualize:– list of accelerators defined to a DB2 subsystem

– list of accelerated tables

IDAA line commands help manage DB2 Analytics Accelerator:– Accelerate/decelerate table(s).

– Enable/disable acceleration for table(s).

– Load data to table(s).

– Start/stop accelerator.

– Visualize distribution/organization keys.

– Confirm whether a accelerated table column has been accelerated/not.

Application Development (New or Legacy Replacement)

Impact on DB2 / Customer– Developers need Test and QA environments

Solution– Use CA RC/Migrator to create test and QA environments.

– Use CA RC/Update to make changes to test objects during the development process.

– Use CA RC/Compare to sync test changes to QA.

– Use CA RC/Compare to sync QA changes to PRD.

Corporate Merger or Acquisition

Impact on DB2 / Customer– Need to consolidate DB2 environments

Solution– Use CA RC/Merger to move objects from the old DB2 environment to

the new DB2 environment without the need to copy the VSAM datasets.

– Real Life scenario took 11.5 hrs instead of the estimated 36+hrs with traditional tools and processes.
