Abstract
This session will focus on a new mainframe DB2® tools customer
or a non-DB2 customer interested in DB2 solutions from CA
Technologies and helping them understand the value
proposition and the real-life use cases (administration, change
management, performance optimization, monitoring, etc.)
where DB2 tools help customers reduce operational costs,
reduce risks associated with downtime/availability, improve
service levels and improve user productivity.

CA RC/QUERY® FOR DB2 FOR Z/OS HDDL LINE COMMAND5

How do I deliver a flawless experience every
time an application touches the mainframe?
In the application economy it’s all about your customers.
You need to think about your mainframe reframed.
Connect mobile-to-
mainframe applications
Create mainframe
infrastructure flexibility
for the future
Unleash the power of
data on the mainframe

Use Case:
Cloning using RC/Migrator (Merger)

CA RC/Migrator (Merger)
§ Move or Copy Table/Index Spaces from one Subsystem to another (could
be same SSID)
§ Shared DASD required between subsystems
§ No requirement to unload and reload tables
§ Copy the VSAM datasets from source subsystem to target including
catalog statistics
§ Flashcopysupported to eliminate outage on source system
§ OBIDs can be reserved or translated in place on target system
Cloning Data using CA RC/Migrator – M Strategy

§ Customer initially used Unload/Load Migration process to
move data from Production to Test
§ Second phase was to remove unnecessary Indexes from the
move process
§ Then converted Migration strategy to use RC/Merger – large
reduction in processing time
§ Implemented FlashCopy Support (RC/Merger R19 feature)
Customer case study

Customer statistics moving from standard Unload/Load method to RC/Merger
Note: Cloning process is now
handling 2-3x
the data originally processed
Using Unload/Load Processing
Removed some unnecessary indexes
Converted to RC/Merger process
Implemented SNAPSHOT with RC/Merger

Specify RC/Merger
Move/Copy Analysis Strategy
Options.
Reserve OBIDS=Y will remove
need to translate OBIDs unless
collision.
Source Execution of Read Only
ensures consistent copy.

Global Changes
allow object
attributes to be
altered on target
system.
Copy Source
Tablespaces to
Target Tablespaces.

RC/Merger will
allocate Target
VSAM datasets
if required.

Call RC/Merger to
Reserve OBIDs if
available.

Use Case:
DB2 Real Time Statistics (RTS) for Automation

DB2 Real Time Stats for Automation
Database Analyzer – Object Selection using RTS
§ DB2 Object
selection based on
RTS using Reorg
best practice
selection criteria
(DSNACCOX like)

§ Execution of PDA
Extract Procedure to
generate Online
Reorgs JOBs for
selected Tablespaces
tied to Object
Selection Profile

§ Online Reorg JCL
generated into
target library for
each object selected
based on best
practice selection
criteria.

Use Case:
Package Compare Integration With Change Control

PPA Package Compare Integration With Change Control
Identifying Access Path Changes

§ Add Batch Process steps to Change Control process in order to
detect SQL performance impact due to SQL changes
§ Current Explain of Package can be used to create the Baseline
§ Future Explain with Comparison to Current Explain to detect
impact of SQL changes
§ Options can be specified to set Threshold value on cost
comparison
Cost Compare analysis

CVCCOPTS contains
options for Cost
Compare report
including thresholds.
Add JCL step to
Change Control
Process to Compare
baseline to future
explain in order to
analyze access path
changes of package.

Package compare of Old
versus New package
compare resulted in 26
improved SQL
statements.

Cost of SQL statement went
from 60 to 1 (ms) since Access
type changed from TS_SCN to
IXDATA.

PPA – New R19 Feature to Simplify Compare Process
§ Rebind Compare Analysis (RCA) command to simplify
compare current / future access paths for a package
§ Issues Current Explain of Package, followed by Future Explain
§ Compares Future to Current explain results and generates the
Rebind Compare Analysis report
§ Show only SQL statements where access path has changed
§ RCA can be issued from most reports where a Package
line exists
Rebind Compare Analysis Report

PPA Rebind Compare Analysis (RCA)
RCA Line command can
be executed on most
reports containing a
Package detail line.
Current/Future explains
following by Compare
with Rebind Analysis
Report for SQL with
Access Path changes.

PPA Rebind Compare Analysis (RCA)
Rebind Compare Analysis report
shows a cost improvement from
44 to 1 (ms) when rebinding
package on DB2 V10 due to
ColFnE=R (Column Function
evaluated at data retrieval)

Use Case:
Detector Reporting and Collection Profile Usage

Detector Reporting and Collection Profile Usage
Define application groups using reporting profiles
Application profiles can be
defined for collections of
PLANs, Packages, CorrID, and
Users which make up an
application.
In this example, RTPPLNMN
and RTPREG are the
collection of PLAN names
that are specified in the
profile that make of the
Application RTPAPPL.

Detector Reporting Profile Usage
Viewing DB2 activity by Application Reporting Profile
View By ‘Prof’ (option F) provides
an aggregate view of all activity
for the selected intervals by all
PLANs defined in the specific
application profiles.
In this example, RTPAPPL is the
application ID associated with the
application profile that
aggregates the collection of
PLANS that make up the
application. All other activity in
the interval is represented by
‘*No Profile*’.

Detector Reporting Profile Usage
Drill down into activity within the selected Application
By selecting an application profile
with an “S” line command on the
View By Profile display, activity
can then be displayed for each
PLAN (or profile type)
individually within the
Application.
Further Drill down to Programs,
Dynamic SQL, or other Keys can
then be selected.

Use Case:
CA RC/Query HDDL Line Command

CA RC/Query HDDL Line Command
§ HDDL Line
command on a
DB2 object will
generate DDL for
the object along
with its Parent
and Dependent
Objects.
Generate DDL for specified object along with Parent and Dependent Objects

Use Case:
Manage DB2 Analytics Accelerator

Use CA RC/Query for IDAA administration
Ability to
Start/Stop/Display
and PING
Accelerator from
RC/Q Accelerator
List

RC/Q Accelerator
Table list report
provides table level
administration of
your IDAA

IDAA Table level
functions are
available to Define,
Alter, Remove,
Load, etc.

§ Load DB2 Table into
IDAA
– RC/Q ALOAD Command
– Can load range of
partitions or entire Table
– Uses IDAA Loader utility
– Most commands such as
ALOAD are available using
Batch Processor Scripts

DB2 Analytics Accelerator
CA SYSVIEW® Performance Management for DB2
§ Subsystem statistics:

Tips and Hints With DB2 Tools

DB2 Tools
§ “?” – Primary and Line commands
§ Freeze / Unfreeze / Report commands
§ QFILE and QPRINT commands
§ ALL primary command in CA RC/Query
§ EQF – Extended Query Facility
– The SQL Line command
§ RC/Query User Defined Line commands
Tips, Hints and Useful stuff

DB2 Tools – Tips Using the ISPF Interface
Use of “?” for available Panel and Line Commands
Enter “?” in Primary or
Line command field to
get a list of available
commands

Freeze, Unfreeze and Report Commands
§ Create Customizable
Report formats using the
Report Command
§ Freeze / Unfreeze
commands allow for fixing
columns to scroll left/right
§ QPRINT/QFILE commands
to print/save report

ALL Primary command in CA RC/Query
The “ALL” primary
command will populate
all object rows with the
associated Line
command to enable a
quick method of
executing a specific
command for all object.
Line command options
can then be applied to
all objects.

EQF – Extended Query Facility
Any screen that contains a
‘Where =>’ field can invoke
the EQF SQL Query Editor.
Y – Create or Update EQF
N – Don’t invoke EQF
S – Execute Extended Query

EQF – Extended Query Facility
Additional Predicate
values and ORDER BY
columns can be added
to the base query being
executed within the
DB2 Tools interface.

CA RC/Query – User Defined commands
§ User defined RC/Query commands are defined via USALINE and
identify the Object type they are available to be used on.
§ User commands can be written in REXX or as a compiled program
and LINKED into the PTLLINE Load Module
USMLINE1 'USER-DEFINED LINE COMMANDS'
USMLINE2 LISTCAT,(TS,IX,T,I), *
'IDCAMS Listcat of tablespace/indexspace'

CA RC/Query – User Defined commands
Available User defined
commands for specified
DB2 Object Type are
listed in the Panel when
entering a ‘?’ Line
command.
Command can be
Selected or entered as
Line command.
Sample REXX command
is provided as example.
