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.

The Solution: CA Performance Analytics
for DB2 for z/OS (Pre-Release)
Visualize changes in DB2 application performance.

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.
Easier Management Through a Familiar Mainframe Interface

Need to Use IDAA to Improve Application Performance
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.
