The need for a mobile app
• The inspiration for mobile
– 24x7 visibility to CICS environments – with out
needing laptops!
– Proactive monitoring to avoid errors before they
happen
– Management Dashboard – management can
access critical application status at any time
• Expected Benefits
Aetna
WUzUP
CICS?
– Mobility == Flexibility for CICS Systems
Engineering
– Respond to issues or simply verify the current
DB2 and MQ status
– Improve overall reliability, availability and
serviceability of CICS processing
Ensure 24X7 processing for our critical online
applications such as Claims and Real Time Eligibility
The Existing Application

Adapter
• Implementation
– Utility used to generate
JSON schemas from
COBOL
– RESTful Adapter
created in Worklight
Studio and deployed to
the Worklight server
– Mobile application
developed to invoke the
Worklight Adapter
What we built – The Mobile App
Launch the WUzUp app.
Use “+” to configure settings.
Specify Userid & password.
Add CICSplex connections.
Indicate which
connections to check.
What we built – The Mobile App
Green = No connection issues.
Red = At least one issue. 8
Lists all regions that have MQ
and/or DB2 Connectivity issues.
The Results
• Expectations were exceeded!
– CICS Support Engineers – easily identify and verify the connectivity
state for the CICS-DB2 and CICS-MQ interfaces across the various
CICS complexes.
– Management Visibility – Management now has the ability to use this
tool to verify/assess the current processing status of the CICS
environments as it relates to DB2 and MQ connectivity.
• Next steps
– Enhance existing app – more functionality for the technicians as well
as enhanced analytics for management. (see next page)
– Develop New mobile offerings – Enable Application Development
partners new capabilities to enhance dev and QA processing.
– Investigate WebSphere Liberty profile and z/OS Connect with CICS
The Results
• Next steps
– Enhance existing app – more functionality for the technicians as well
as enhanced analytics for management.
– V2 Inquiry only
• CTG Connectivity
• Short on Storage
• Max Tasks
• Max Transaction Class – TCLASS
• QMON off/on
• System/Transaction dump thresholds exceeded
• CICS User Data Table Full condition
• Any other data or statistic that can be queried by CPSM
– V3
• Fix Button
• Develop for other environments, DB2, MQ, etc.
Mobile enabling mainframe applications will enhance the
experience of employees and customers
