Our Vision – Putting information to work for you

Gather database statistics at regular intervals

User-defined policies and thresholds

Sensors….gather database statistics at regular intervals

Works with you – your way – in your environment:

� Integrated in regularly used utilities– HP Image Copy(FF and FP), HP Pointer Checker, DB Reorg Expert, FPA

Analyze, FPA Reorg, FPO Analyze, FPO Reorg

5 © 2013 IBM Corporation

� Automation of sensor capture– Autonomics scheduler ensures sensor data capture at frequency that you

require

� When you need it!– Ad-hoc / job scheduler batch submitted sensor capture

Page 6: IMS Tools Smarter IMS - IMS UG 9.11.13 eMeeting

Policies…User defined policies and exceptions

� Policy definitions are used to evaluate specific database states– Threshold values are compared against sensor data for a given database or group of

databases

– When thresholds are met or exceeded, exceptions occur

� Works “out of the box”– Ships with predefined policies and threshold values

6 © 2013 IBM Corporation

– Ships with predefined policies and threshold values

– Full ISPF interface provided for policy management

� Customizable to fit your shop– You can define your own sets of threshold values

– Customize the messages sent when exceptions do occur

– Specify who receives which messages and how• WTO, e-mail, or text

Page 7: IMS Tools Smarter IMS - IMS UG 9.11.13 eMeeting

Automation…Recommending and Taking Corrective Actions

� Passive Autonomics – Automates collection and analysis of Sensor Data

– Recommends when databases should be reorganized• With email or text notifications

– Enables DB Reorg Expert’s conditional reorg

– Provides a scheduling feature that allows you to control how frequently sensor data is collected and how frequently policies are evaluated

7 © 2013 IBM Corporation

sensor data is collected and how frequently policies are evaluated– Flexible scheduling around pre-defined PEAK times

� Active Autonomics– Actively initiate recommended actions on user-defined database groups

• Discovery feature for identifying related database groups

• Ability to manage and coordinate reorganization of multiple IMS database

groups as if reorganizing a single database

• Flexible scheduling only in pre-defined Maintenance windows

Page 8: IMS Tools Smarter IMS - IMS UG 9.11.13 eMeeting

On the road to a smarter IMS

� Conditional Reorganization - DB Reorg Expert− Sensors determine need for reorganization

− Reorganization only runs if needed

� Notifcation of exceptions− Email, text messages

− Alert DBA to consider taking action

8 © 2013 IBM Corporation

� First we had IMS Tools Knowledge Base– Report Repository

– IMS Tools Utilities updated to write their reports to a repository by database

� Then we developed Sensors and Policies: – Sensor capture

– Policies pre-loaded by database type

– User-customizable

− Reorganization only runs if needed

− Pre/Post reporting

� Sensor Data Capture

– Standalone sensor

– Integrated utility sensor capture – DB Reorg Expert, HP Image Copy,

HP Pointer Checker

– Autonomics control sensor capture

� User Group Definitions

� Policies

– Pre-defined policies

– Policy definition and customization

– Policy evaluation and action determination
