IMS Administration Console Goals

• Provide a single holistic, easy-to-use interfaceto manage IMS systems and databases

• Consolidate information from various tools to

paint a more complete picture of IMS systems and databases

• Leverage the latest web technologies for a richer user experience

• Access from anywhere via the Internet using standard web browsers

• Integrate a context sensitive help system as a learning aid for new

IMS DBAs and System Programmers

• Begin with integration of our Autonomics Solutions

• …Extend integration to support all our IMS Tools


Administration Console Benefits

• Install once, access anywhere via the Internet

• Single, server-based installation

• Access through standard web browsers

• Safety and security features are built in

• Uses SSL and RACF authentication

• Works “out of the box”

• Immediately view your databases using your existing DBRC groups or Autonomics

Director monitor list

• Easily customized

• Define your own groups of databases to view

• Consolidated information at your fingertips

• Summary dashboards provide total counts of exceptions and overall status for

database groups

• Database dashboards pull together information from many separate tools

IMS Tools Vision

• Sensors collect resource statistics

• Policies evaluate sensor data and identify potential problems

• Automation orchestrates the collection and evaluation of sensor data

• Modernization presents an interactive modern interface for managing the system

Sensors: Collecting the Basic Information You Need

• Statistical point-in-time sensor data on your FF/FP Databases

• Stored in IMS Tools Knowledge Base repository

• Historically maintained per user specifications

• Over 60 separate data elements related to space usage, optimization, and

fragmentation

• data set extents, DASD volume usage, data set free space, roots distribution, RAP usage,

CI/CA splits, and IMS free space, etc

• Two methods of collection:

• Standalone database Sensor utilities for full-function and Fast Path databases

• Integrated with existing IMS Tools

• Integrated Tools support

• High Performance Image Copy, High Performance Pointer Checker

• Fast Path Analyzer, Fast Path Online Pointer Checker8

SensorsSensors


Policies: Using Sensor Data to Make Decisions

• 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

• 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

Automation: Delivering on our Vision

• IMS Tools Autonomics Director

• Passive autonomics for IMS databases

• Automates ongoing database monitoring and maintenance tasks based on a

detailed understanding of the current state of your IMS databases

• Recommends when databases should be reorganized

• Provides a scheduling feature that allows you to control how frequently sensor

data is collected and how frequently policies are evaluated

• Customer value

• Help prevent problems before they occur

• Higher availability and performance through optimally organized data

• Consistent and reliable monitoring of database status

• Regular collection/evaluation at predefined intervals

Autonomics Director Overview

• Automatic collection of Sensor data

• Integrates with IMS Tools image copy and pointer checker processes

• On Demand collection/evaluation for immediate issues

• “I have a problem and need the information now!”

• Automatic analysis and evaluation of database status

• Based on user-defined policies and thresholds

• Recommendation for reorganization

• Easy to understand: simple “yes” or “no”

• E-mail or text notification when a reorganization is recommended

• Alert DBA to consider taking action

• Flexible scheduling around peak workloads

• Doesn’t interfere with production throughput or response


Autonomics Director Overview

• Works with existing job schedulers

• Exploits the power of IMS sysplex

• Redundant servers for highest levels of availability

• Spreads data collection/tools workload based on system capacity and status

• Easily customized for groups or individual databases

• Auto-discovery of databases and existing database groups

• User-defined groupings: “These are the databases that I’m responsible for”

• Group-assigned defaults propagate to individual databases

• Intuitive user interfaces for all users

• Full ISPF interface

• Integrates with new IMS Administration Console for viewing database status on the web

• Available with upcoming release of IBM Tools Base Pack

• No charge product


Adding database(s) to your monitor list • Your Monitor List is the custom list of databases you’re interested in…

All of your environment’s databases are discovered at run-time by our Auto-discovery

function, you can view all or search for the particular database(s) you want added to your Monitor List for automatic monitoring, in this

example we select one database DEVICEDB


Setting your monitoring criteria• You can set how often the database should be evaluated, how many

evaluations to save, and which policies to use in the evaluation

Policies are fully customizable, however, we ship default policies with default threshold settings to get you up and running quickly. You can select

policies by DBTYPE, DBDNAME, or Policy Name


Scheduling an evaluation On Demand

We monitor and evaluate databases automatically when allowed but will avoid your peak operations times

once you specify them. However, you can always schedule an On Demand evaluation if you suspect a database issue and need the latest sensor data and

policy evaluation now.

• Databases will be monitored and evaluated automatically once you specify your

peak times (not shown) but you can always schedule an On Demand evaluation


Immediately…• Maximum flexibility is provided to get you the most current information available

when you need it, so decisions are never made using stale data


View the resulting recommendations• We keep it simple, if a database reorganization is needed based on the policies

you set you’ll see ‘Y’ if not, you’ll see ‘N’ … no guess work here

You can drill down further to see just which policy exceptions were triggered


View the detailed exceptions via ISPF Browse• Complete transparency so you can see exactly why a reorganization is being

recommended, we’ll even send you an e-mail or text message to notify you
