- 1. © Copyright IBM Corporation 2014 Connecting System z to Mobile • Client contest to create mobile apps connecting to the mainframe • Participants were provided access to IBM mobile enablement technologies and System z mobile experts • Winner announced in Enterprise 2014 Tuesday General Session • Clients Aetna and Verizon present their mobile apps at Enterprise 2014 • Stay tuned for future Mainframe Mobile App Throwdowns!

- 3. Why build a mobile mainframe app? • The problem we started with – Checking the status of a Mainframe took too long – Required laptop/desktop, VPN and many clicks… • The app of our dreams – On-call team members can quickly check the status of a Mainframe from anywhere, anytime – Speedy – top priority – Smart and customizable – not just another 3270 emulator Helping us maintain our SLAs by enabling us to find out what is wrong with the system faster.
- 4. What we built © Copyright IBM Corporation 2014 We could mobilize our health checks by interfacing with the z/OSMF REST API’s to connect with the JES Spool, allowing us to be able to submit jobs and get the output.
- 6. Biggest challenges • We had several obstacles to overcome 1. We had to be able to accept and process a self-signed certificate that z/OSMF sends 2. For our iOS version, we have a proxy that must be authenticated during development 3. Creating a queue that would ensure jobs were not consistently submitted. (1st person gets through, everyone else piggy-backs) 4. Figuring out how to parse the job output and what information we want to use 5. Integration with our Enterprise App Security team while still maintaining the same functionality we originally envisioned
- 7. Looking ahead to Version 2 Submitting inline JCL Viewing job JCL Showing job details (SDSF view) The code is there to easily parse whatever information we want, and work with teams to determine what ‘GO’ means for them.

- 10. 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 – 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 WUzUP CICS?

- 13. 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
- 14. 14 Green = No connection issues. Red = At least one issue. Lists all regions that have MQ and/or DB2 Connectivity issues. What we built – The Mobile App
- 15. The Results • Expectations were exceeded! – CICS Support Engineers – easily identify mobile process to 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 – 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 Mobile enabling mainframe applications will enhance the experience of employees and customers

- Version 2 which is on the last slide of the powerpoint we submitted will allow us to pull up what is the equivalent to an SDSF screen to show all of the details about the job. We will also be able to submit inline JCL which will give users the option to submit a quick job they think might be able to get more info or to possibly fix a problem.
- What was the business need that drove you to want to build a mobile app? A mobile implementation of the current CPSM WUI utility will enable Aetna CICS Systems Engineers to provide 24X7 support of the various CICS processing environments without being tied to a laptop. With the initial mobile offering CICS Systems Engineers will have the capability of verifying the status of the DB2 and MQ connections across Aetna’s CICS complexes both proactively and after an alert was raised. Additionally, the mobile offering can be utilized as a dashboard for management to view the current status of the DB2 and MQ connectivity for the CICS platforms. Describe how creating the mobile app could enhance the experience of a customer or employee. This application will provide mobility and flexibility for the CICS Systems Engineering support staff in respect to on call coverage responsibilities. The CICS technicians' will have the flexibility of responding to connectivity issues or simply verifying the current connection statuses for DB2 and MQ from a mobile device. Mobilization enables a more proactive posture as well as timely reaction to issues while ensuring the overall reliability, availability and serviceability of the CICS processing environments and continued 24X7 processing for our critical online applications such as Claims, Real Time Eligibility etc. ..
- Describe your existing infrastructure. Executing CICS Transaction Server (CICS TS) V5.2 on z/OS Version 2.1. in our OLTP Lab environment. The mobile application was created using Worklight and the WUzUp application interfaces with the CICS CPSM online Application Programming Interface(API).
- Describe how you went about the mobile enablement of your mainframe applications The DHFLS2JS utility was used to generate JSON schemas from our Cobol Commarea A matching RESTful Adapter in Worklight Studio was created and deployed to the Worklight server The mobile application was developed to invoke the Worklight Adapter Include key technical components and/or architecture diagram Worklight CICS TS V5.2 WUzUP utility created to interface with the CICS CPSM online API Highlight any key obstacles you overcame Worklight Studio is not a standard software deployment therefore a special installation was required for invocation/execution
- On subsequent launches and Refreshes, REST JSON calls will be made to all ‘checked’ connections Green light indicates no CICS regions in that Plex have MQ or DB2 Connectivity issues Red light indicates at least one CICS region, in that Plex is not connected to MQ and/or DB2 Touch the Red Light ‘Arrow’ for details
- What were your expectations and did you meet them? Expectations were exceeded. Provide CICS Support Engineers a mobile process to verify the connectivity state for the CICS-DB2 and CICS-MQ interfaces across the various CICS complexes. Additionally, 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. What worked well? The DFHLS2JS utility provided for conversion of Cobol to JSON worked extremely well Are there outstanding issues you still need to work on, or need help with? Preference was to exploit/implement z/OS Connect and WebSphere Liberty Profile (WLP). However although IBM plans to deliver Liberty z/OS Connect support with CICS TS V5.2 z/OS Connect executing under CICS requires Liberty fix pack 8.5.5.2 + 2 interim fixes (or a later fix pack). CICS TS V5.2 is currently delivered with Liberty 8.5.5.1. and there is no stated ETA for an upgrade. What are the future plans for your app? Going forward, this initial mobile application will be enhanced to provide more functionality for the technicians as well as enhanced analytics for Management. Additional mobile offerings are planned targeting our Application Development partners to purge transactions and perform new copies in the development and QA processing environments.
