Projected trends recorded in this way represent accurate growth measurements.
These projections can be used to identify needed changes in system
configuration with sufficient lead time to permit orderly procurement and
installation of new resources. This will provide the capacity required over time
as your system grows.
30.5 Operations Management
30.5.1 Overview
Operations management includes tasks for planning distributing, evaluating, and
controlling workloads. It also addresses the resource availability needed to
support the workloads.
The daily tasks required to activate system components, start workloads, and
monitor activities to discover any discrepancies are the heart of supporting the
system users. In a small environment these tasks may be carried out by a small
number of people; in many cases the systems programming and daily operations
functions are carried out by the same people. In the OS/390 environment, the
opportunity for greater growth leads to the separation of operational tasks from
systems programming tasks. Operations becomes the 
first line of defense
when a deviation from the norm occurs.
The operations management discipline is oriented towards defined workloads. It
covers the activities of starting and stopping systems and resources (including,
but not limited to, host systems, workstations, networks and databases) and
receiving and responding to operational notifications. However, it encompasses
more than the traditional operator
s console commands, messages, and
responses. The objective is to allow management to set policies to manage
workloads and resource availability, and to automate the interactions required to
implement these policies.
Operations management should provide the flexibility to centralize control of
some functions and distribute others. This ability, together with other enhanced
operator functions, will reduce the cost of operations.
The requirements for operations management may include:
Lights-out operation - automated operations, ranging from simple command
lists to automate a trivial or repetitive operator function to applying Artificial
Intelligence (AI) to automate operator decisions.
Data protection - automated backup and archiving of data files.
Monitoring - consistent, easy to use, graphical operations interface(s), that
display system and network topology and resources.
30.5.2 Tasks
The operations process includes:
Workload planning - definitions, analyses, and reports of the enterprise
s
workloads, both actual and anticipated.
Operations planning - determines the structure needed to support the
availability of systems and resources for the defined workloads.
