Overview of z/OS Management Facility


Overview of z/OSMF

IBM z/OS Management facility (z/OSMF) delivers on IBM’s strategy for mainframe simplification and modernization

z/OSMF provides a modern, browser-based interface for managing the z/OS system

z/OSMF helps you manage solutions rather than specific IBM products

Automated tasks help reduce the learning curve and improve productivity

Embedded user assistance, wizards, and tool tips help guide users through tasks

z/OSMF has a zero price for z/OS customers

z/OSMF helps system

programmers to more easily

manage and administer a

mainframe system by

simplifying day-to-day

operations and administration

of a z/OS system.

Not just a graphical user interface:

The z/OS Management Facility is intelligent, addressing the needs of a diversified skilled workforce and maximizing their productivity.

Overview of z/OSMF (cont’d)


Overview of z/OSMF: Plugins

System management capabilities to simplify and help standardize common tasks:

Capacity Provisioning: Create, edit, and activate domain configurations and capacity provisioning policies, and monitor Capacity Provisioning Manager status for domains.Configuration Assistant for z/OS Communications Server: Configure TCP/IP policy-based networking functions.Resource Monitoring and System Status: Obtain dynamic, real-time performance/status metrics for z/OS sysplexes, AIX system complexes, Windows system complexes, and Linux system complexes.Software Management: View, inspect, and report on software instances to simplify the management of your z/OS software. Workload Management: Create, edit, and activate WLM policies to offer a convenient way of adjusting policiesISPF: Launch ISPF functions in the z/OSMF user interface. Incident Log: Capture, package, and send SVC dump diagnostic data to simplify problem reporting.Workflows: Perform a guided set of steps (for example, to configure components or products in your installation).

z/OS Management Facility is a Web 2.0 application on z/OS

z/OSMF manages z/OS from z/OS, no client install required

Browser communicates with z/OSMF via a secure connectionConnect from anywhere, anytime. No 3270 emulator required.z/OSMF V2R1 is supported on z/OS V2R1 (must be ordered from IBM)z/OSMF V2R2 is supported on z/OS V2R2 (included in z/OS base)

z/OSMF uses industry-standard technology like Java, DOJO, JavaScriptJava is eligible to offload to specialty engine

z/OSMF communicates with security server on z/OS and other components as needed

• Efficient code base: WebSphere Application Server Liberty profile• Workflow files reside on z/OS system in USS or dataset members


Workflows in z/OSMF

• Workflows provide a guided flow through end-end steps required to accomplish a task.

• A z/OSMF Workflow is created by specifying a ‘Workflow Definition File (XML)’ and a ‘Variable Input File’.

• The ‘Workflow Definition File’ contains definitions for variables used by the workflow and the steps to be performed.

• Steps may be manual or automated.

• Within the steps, a user can update and submit jobs, execute scripts, etc.

• The ‘Variable Input File’ contains values for some or all variables used by the workflow.

• Providing values of all variables in a workflow allows it to be run automatically without user intervention.

• Variable values may also be solicited from the user from within a workflow step.

10


Workflows in z/OSMF (cont’d)

• A workflow is only meant to be run once.

• Want to repeat the task? Create another workflow.

• Workflows remain in z/OSMF, including all history and job output, until manually deleted.

• Steps in the workflow can be assigned to specific roles, such as “system programmer,” “security administrator,” or to an individual to complete specific tasks.

• Step owners are notified through email or z/OSMF interface when certain events occur (i.e. requested to complete a step, automation succeeds/fails).

• Steps may define a dependency on another step.

• All actions taken on the system are performed under the user’s ID and within the constraints of the user’s security authorizations. (z/OSMF provides no inherent authorization to take an action on the system.)

Provides a web GUI with wizards, help, links, instructions, and tutorials that guide users through complex tasks spanning multiple IMS subcomponents and operations.

Does not require end users to have in-depth knowledge of the environment, naming conventions, processes and procedures.

Does not require end users to have in-depth knowledge of IMS operations.

Relatively simple programming (XML, JCL).

Flexibility (conditional statements supported).

REST API availabilityHome-grown or 3rd party portal may be used for self-service provisioning.

How Will This Help IMS Users?


How Will This Help IMS Users? (cont’d)

Workflows can be used to simplify IMS operations, such as:DB deploymentApplication deploymentSystem provisioningRestart of IMS(s) and all its subcomponents

A workflow can be used to manage IMS along with other subsystems (CICS, DB2, WebSphere MQ).

Saves time for experienced IMS system programmers and DBAs and also helps novice users be more productive

A novice IMS system programmer can provision a full IMS system, with minimal knowledge of IMS internals, in 5 minutes.

Validation

Once IMS is provisioned, it can be verified with IMS commands, Management Console, etc.

ISPF interface is

available in z/OSMF,

so you don’t have to

leave the browser.
