Edition d’applications


Workload Modelling, Planning and Forecasting

� Centralized modeling of heterogenous batchworkloads across the enterprise

– Centralized repository for all batch objects (e.g. calendars, jobs, job-streams, resources, etc..)

– Centralized security, authorization and auditing

� Centralized planning for calendar-driven and event-driven batch workload

– Viewing and documenting current and forecast plans

– Viewing and documenting dependencies among jobs, resources, calendars, etc…


Workload Modeling

Efficient and innovative way to prepare workloads, develop workflows to map Business Processes, and manipulate existing or new definitions.

How do I monitor my own jobs?

� Single point of monitoring and control for batch workload and batch environments

– Monitor workload jobs events (e.g. job start/end) and alerts (i.e. job in error, late, long)

– Monitor events related to scheduling infrastructure health

– Monitoring of business Critical Jobs, critical path, critical predecessors, risk level

� Dashboard – to – single job log easy path

� One-click access to key information

� Drill stack to go back and forth between the steps


Monitoring and Modifying Conditions in CP


Business needs

� How to improve Service Level Agreements, automate operations and reduce costs?

� How to monitor and measure the impact of workloads against business service delivery?

� How can I filter and prioritize critical events from a flood of system-wide events?

� How can I ensure business priorities to get the right attention, and speed their implementation time?

� How can I enable proactive reaction?

Solution

Allows identification of criticalworkload

Calculates critical path to criticalworkload and keep itdynamically updated

Takes autonomous remedialactions for lagging jobs inthe critical path

Gives a view of the critical end points and the possibilityto understand how well workload isprogressing to reachthat point to trigger proactivehuman reaction

Workload Service Assurance: Identifying critical workload

� Every production has some critical jobs that must be completed by a given time

5:00

6:00

� Critical jobs may be any distributed or mainframe jobs in the end-to-end network

Workload Service Assurance: Critical Path determination

� Automatic determination of critical path tocritical jobs

� Through the network of internal and externaldependencies

�Path with minimum slack time�Cannot be delayed without delaying the

critical job

� Dynamic adjustements: an alternate legmay become critical

�Unexpected anomalous condition in the critical jobs predecessors

�Unplanned workload


TWS z/OS - Workload Service Assurance

� User identification of critical jobs and their deadline

� New views (ISPF, JSC, WEB UI and TEP views) for Critical Jobs and Critical Paths

� Critical Path is dynamically recalculated when unexpected delays occur on jobs outside the original Critical Pathy or for jobs dynamically added to the plan

� Graphical and dashboard views of critical Jobs and their risk to miss deadline (High, Potential, no-risk), with drill-down navigation to predecessor jobs causing the risk.

� Automatic promotion of jobs on critical path for critical jobs in high or potential risk



Reporting


� Historical data analysis and statistics, detecting jobs with exceptions: success rates, late starts, long durations, missing deadlines, etc …

� Tuning the workload of workstations: job runs, comp aring workload, etc…

“call Def Billing”

MultiMaster proposal: two primitives

1: Submit and Track. I (requestor) want you (executor) to execute this workload and let me know about status, completion, results, etc.

2: Cross dependencies. I (successor) want to start workload after you (predecessor) have finish.

Case A: z/OS to z/OS

� Primitive 1: submit and track

– Several possibilities, ETT, PIF calls. To be examined further.

� Primitive 2: cross-dependencies

– Implementation through common tracker.

– Scenario steps

• TWSz B (predecessor) runs the workload. At the end of each application, a best practice instructs to run a dummy operation on the common tracker

• TWSz A (successor) has the workload defined with the same name. • When TWSz B job executes, TWSz A sees the jobs and tracks to completion.

• Workload on TWSz A that depends on the job can start right after completion.
