CA IDMS™ as a Web Service Provider
Re-using CA IDMS™ Applications
Application re-use issues
• Separation of business from presentation logic
• How you can create APIs
• Invoking the business logic from the modern
environment
• Think in terms of components
Presentation Interface
Call Interface

Presentation Interface
Avoids the logic separation issue
Find the data in the screen buffer
• Screen geometry
• Field names
Control the flow of screens
• Scripting language
Can be sensitive to application changes
Think in terms of components
• Not complete 3270 applications

Call Interface
Extract logic from application
• Subroutines
• Map-less dialogs
• Extracted code
Invoke using
• Socket programs
• SQL procedures with JDBC or ODBC
• CA IDMS™ web services
• CICS web services

CA IDMS™ SQL Procedures with CA IDMS™ Server
CA IDMS™ is part of the service provider
Define with CREATE PROCEDURE
• Reuse business logic in:
•CA ADS™ map-less dialog

Implement web service on an app server
•Tomcat, WAS, …
Call with standard APIs
•SQL CALL statement
•ODBC
•JDBC

CA IDMS™ Socket Program - Provider

Service Consumer
Does most of the heavy lifting for you
• Wraps request in SOAP envelope
• Binds to HTTP protocol
• Sends request and receives reply using TCP/IP
• Unwrap XML reply from SOAP envelope
You supply a program
• Specify request as an XML document
• Extract response from XML document

CA IDMS™ is the service provider
Provides HTTP server and SOAP wrapper
User written program implements the
service
• Extract request from XML document
• Processes request
• CA ADS map-less dialog
• COBOL program
• SQL Procedure
• Formats response as an XML document

Adding Value to CA IDMS™

CA IDMS™ M3A Service
Monitor, Measure, Manage, & Alert
§ Business Benefits
– Many customers need basic “care and feeding” services for their
critical business systems
– Service provides a skilled technician to
§ Measure, Monitor, Manage & Alert
§ Yearly based retainer service that keeps core CA IDMS™ systems
delivering value to our customers
§ Daily check-ins, quarterly reviews, performance suggestions, situation
alerts
§ Does not replace, but integrates with technical support

CA IDMS™ M3A Service
Start-up activities – Initial interview, inventory, performance baseline and site report
Daily Activities
– Review current system activity, recent activity logs, recent table
activity, alert on required corrective activity, and record activity
Monthly Activities – Repeat measurement activities, update updated site report
Quarterly Activities – Review CA IDMS™ maintenance availability
Staffing – Primary and backup M3A technician
Internal – CA IDMS™ and Support Engineers
External – CA IDMS™ Partners – Trained and Certified by CA
Coordination
– Single repository for data
– CA Services Clarity Project Management web site
– Dev. and support synchronized with M3A Service technicians
Fee – Yearly based retainer plus T&E

CA IDMS™ Performance Monitor
§ Customer Value
– CA IDMS™ Performance Monitor provides the only real-time monitoring for CA IDMS™:
§ Ability to monitor all CA IDMS™ systems in one LPAR – key performance measurements
§ Integration with CA SYSVIEW – monitor systems from SYSVIEW
§ Ability to monitor resource utilization and look for problem areas and resource contention
§ Ability to cancel “problem” tasks from CA IDMS™ Performance Monitor or CA SYSVIEW
§ Customer Benefits
– Cost avoidance by detecting and correcting problem situations before they occur
– Ability to baseline resource utilization and better predict growth and capacity needs
– Improved ability for remote monitoring and tuning of CA IDMS™ environments
– Loss due to “Production Availability”

CA SYSVIEW® Performance Management
§ Customer Value
– CA SYSVIEW provides real-time monitoring for your entire z/OS environment
– CA SYSVIEW is ideal for customers who want to monitor a number of systems including:
§ z/OS system resources
§ Datacom/DB
§ IDMS/DB
§ CICS
§ … and other resources
* To use CA SYSVIEW with CA IDMS™ requires the Performance Monitor option
– Cost avoidance by detecting and correcting problem situations before they occur
– Ability to baseline resource utilization and better predict growth and capacity needs
– Improved ability for remote monitoring and tuning of CA IDMS™ environments
– Loss due to “Production Availability

CA IDMS™ Presspack
§ Customer Value
– Data compression can result in significant savings in disk space requirements
§ Translates into dollar savings in monthly rentals, maintenance, floor space and channel costs
– Helps reduce backup/archival processing and improve data security
– CA IDMS™ Presspack’s compression efficiency makes it an ideal tool for compressing large-volume databases
– Fully zIIP-able means our compression utilizes the extremely efficient, low-cost zIIP engines to do all compression
and decompression processing
– Reduces DASD footprint by 30-70% -- saves real dollars
– Improves memory use within the database region
– Benchmark tests have shown that converting an compressed IDMS table to compression saves enough physical
IO CPU to offset CPU used to do compression -- but the CPU is now zIIP which is significantly cheaper

CA Mainframe Application Tuner
§ Customer Value
– Delivers unique functionality to monitor and measure COBOL and CA IDMS™ ADS applications
running in the CA IDMS™ environment
§ On Demand z/OS sampling for any application
§ CPU execution/delay activities for Program, Subsystem, Database and I/O
§ Pinpoint code and stored procedure inefficiencies to the source level
§ Comprehensive detail reporting for System Support Experts
§ Proactive automated measurements based historical trends or program changes
§ Drill-down ISPF Interface for z/OS data usable by Application Development, Database and Quality Assurance
personnel which presents performance data in graphical form
– Quickly measure application performance and pinpoint problems and delays
– Streamlines application life cycle management
– Enhances ability to maintain & manage business critical legacy application code

vStorm Connect Data Streaming for Big Data
§ Customer Value
– Customers need to “share” existing critical business data for data analytics platforms
– Cooperative processing model with Veristorm allows CA IDMS™ data to be uplifted as needed to the
various Big Data platforms
– Cost avoidance
§ By allowing existing reliable systems to continue doing their work
§ Using Big Data platforms to store large amounts of data (cheaply) for consumption by analytics engines
– New analytics possible using key Big Data concepts such as
§ Point-in-time data allowing a customer to see data content at some point in the past
§ Fraud analysis
§ Business compliance analysis
