5. Sub-capacity pricing
IBM MLC software charged at peak MSU usage
Not based on full machine capacity
Key metric is the 4 Hour Rolling Average (4HRA)

Difficult to understand…doesn’t provide cost.
Just a reporting mechanism for IBM’s billing system…
Does not identify opportunities for savings….

10. 10 Steps to Reducing
Mainframe MLC Costs
1. Understand the Cost Base
2. Analyze Peak Workloads
3. Implement Capping
4. Review Workload Placement
5. Leverage Technology – the Benefit of Technical Currency
6. Review the SCRT Process
7. Manage the Entire Software Portfolio
8. Evaluate Possibilities to Qualify for Special-Situation Terms
9. Investigate Alternative Licensing Metrics
10. Plan Procurement Negotiation Strategy

Analyze
Negotiate
Take Action

11. Need to think differently
• Taking MLC cost savings to the next level
• Overcoming technical limits
• Thinking outside the box

12. BMC Subsystem Optimizer for zEnterprize®
(Subzero)
The Why…
– IBM requires that CICS, DB2, and/or IMS DB run on the
same LPAR if a CICS transaction access DB2 or IMS DB
– Increases MLC since all are billed at the combined peak
The How…
– Remove this IBM requirement and lower MLC
– No application code changes required
– Utilizes IBM published facilities
The What…
– Flexibility on where you can run CICS, IMS, and DB2
– Enhanced system redundancy and recovery options
– Further workload balancing options

LPAR2
1. CICS application SQL or DL/I calls are intercepted by Subzero
2. Subzero routes the data access request to the appropriate DBMS
3. DB2/IMS DB processes the data request and returns the requested data
4. Subzero routes the result set back to the initiating CICS application

Controlling Agent
When the CICS transaction issues a DB2 or IMS data request:
1. Subzero Common Code intercepts the request
2. Uses XCF to route the request to the Subzero Subsystem
Server for that database
3. The Subzero Subsystem Server
gets the data from DB2 or IMS DB
4. Uses XCF to send the data to the
Subzero Controlling Agent
5. The Subzero Controlling Agent sends the data back to
the transaction via the Subzero Common Code

21. Subzero transparency and fallback
Utilizes IBM published facilities
– Standard IBM CICS/DB2/IMS DB interfaces
– Subsystems think they are communicating directly
– All existing CICS, DB2 and IMS commands will respond as expected
– Single-Phase or Two-phase commit protocols are preserved; data
integrity is maintained by the requestor
WLM classification and accounting
– Information is propagated from the client address space to the
Subzero Subsystem Server address space
– Allows WLM performance monitoring to include these address spaces
in its service policy management
No application code changes
If a local DB2 or IMS instance satisfies the CICS connection request,
Subzero steps out of the way and allows processing as normal

22. Enabling Subzero
Complete installation and product customization
Define the Subzero configuration
– Uses DBC and LGC to define targets (Remote Subsystem Access)
– Subzero will support both Local and Remote Subsystem Access
CICS
– Add Subzero product libraries in CICS STEPLIB and DFHRPL
– PLT Changes
• Subzero code runs as first pass PLT program
– DBC must be started before CICS
– IMS and/or DB2 libraries required to support local connectivity
Subzero Requirement
– CICS 4.1 and later
– DB2 10.1 and later
– IMS 12.1 and later
– z/OS 1.12 and later

23. MainView for DB2, MainView for IMS and MainView for CICS were
enhanced to facilitate Subzero control and monitoring
– New 3270 and MV Explorer views and hyperlinks
– Use Subzero API to collect component data
– Enhancements through PTFs
Subzero Monitoring

24. Roadmap
Subzero 2.0 – September 2015
– Installation Verification Program (IVP)
• Available now as a 1.0 PTF
– IMS TM to DB2 support
• Beta May/June
– MQ separation from DB2 for MQ shared queues
– MQ separation from DB2 for MQ running DB2
stored procedures
Subzero future plans
– DB2 and IMS DB batch job support
– Separation of MQ from CICS

25. BMC Subzero
Significantly reduce MLC costs
Add operational flexibility to critical workloads
running on CICS with DB2/IMS DB
• Removes the IBM requirement that subsystems must
reside on same LPAR
