What is the IBM z/OS Management Facility?

The Application StackBrowser

HTTP(s)

• The IBM z/OS Management Facility is now a part of z/OS V2.2 that provides support for a modern, Web-browser based management console for z/OS.

• The z/OS Management Facility applications run on the z/OS enabling you to manage z/OS from z/OS

– Information is presented on a workstation using a browser

• The z/OS Management Facility requires:– z/OS Communications Server– Security definitions (SAF)– Other components and functions are required for specific z/OSMF plug-ins– IBM 64-bit SDK for z/OS Java Technology Edition V7.1 or V8.0 ç zIIP eligible!

z/OSMF 2.2 functions

•Notifications and Workflow *(R2.1) •Configuration category

• Configuration Assistant for z/OS Communication Server application• Simplified configuration and setup of TCP/IP policy-based networking functions

•Links category• Links to resources - provides common launch point for accessing resources beyond z/OSMF

•Performance category • Capacity Provisioning (updated)manage connections to CPMs, view reports for domain

status, active configuration and active policy.• Resource Monitoring, System Status - provide integrated performance monitoring of

customer's enterprise• Workload Manager Policy Editor application• Facilitate the creation and editing of WLM service definitions, installation of WLM service

definitions, and activation of WLM service policies

•Problem Determination category• Incident Log : provide a consolidated list of SVC Dump related problems, along with details and

diagnostic data captured with each incident; facilitate sending the data for further diagnostics.•Software category (updated)

• Management: deployment of installed software simpler and safer, manage service levels and product levels

•z/OS classic Interface category•ISPF Task integrate existing ISPF into z/OSMF to enable tasks from single interface and ability to launch to ISPF functions directly•z/OSMF Administration category

• z/OSMF authorization services for administrator:- dynamically add links to non-z/OSMF resources; application linking manager(R13)

•z/OSMF Settings category (New!)• Manage FTP destinations and systems

z/OSMF Resource Monitoring

Browser

z/OSMFResourceMonitoring

► Browser connects to z/OSMF► z/OSMF Resource Monitoring can connect to all systems

where the RMF Distributed Data Server (DDS) is running► DDS retrieves z/OS performance data from all images of the

sysplex where the RMF Monitor III gatherer is active
