Processing policy time conditions
The provisioning condition that contains the time condition can
also contain workload conditions 
or
utilization conditions
. Based on the provisioning PI durations
of all associated workload conditions and based on the provisioning utilization durations of
all associated utilization conditions, the Provisioning Manager
calculates the time at which observation of the workload or utilization must start in
order to allow provisioning at the start time, if necessary. This
calculated time is referred to as the observation start time.
or
utilization conditions. Based on the provisioning PI durations
of all associated workload conditions and based on the provisioning utilization durations of
all associated utilization conditions, the Provisioning Manager
calculates the time at which observation of the workload or utilization must start in
order to allow provisioning at the start time, if necessary. This
calculated time is referred to as the observation start time. Note: The
Provisioning Manager can run at different times on different systems,
and it normally observes several other systems. Because these systems
can be running in different time zones, the Provisioning Manager calculates
and reports all times based on a common time zone. This common time
zone is the Coordinated Universal Time (UTC).
One of the parameters of a nonrecurring time condition is the start time, which defines when the provisioning of additional capacity can start. For a recurring time condition, start time is the combination of start time and a selected day of the week that occurs between the start date and the end date. Recurring time conditions are processed as a set of nonrecurring time conditions.
The state of time conditions at runtime is calculated based on
the current time. A time condition can be in any of the states in
the following list, depending on the current time, the enabled state
of the time condition, and the enabled state of the policy. The enabled
state of the time condition depends on the enabled states of the provisioning
condition, rule, and policy that contain this time condition. If all
of these policy elements are enabled, the time condition is also enabled.
The states of time conditions in the active provisioning policy
can be reported by the Provisioning Manager in the policy report.
For more information about this report, see The policy report. The enabled or disabled
states of the rule and provisioning condition policy elements can
be changed by using Provisioning Manager commands. For more information
about these commands, see ENABLE POLICY and DISABLE POLICY. The state of the active policy itself
depends on the processing mode of
the Provisioning Manager; for more information, see Processing modes. The policy is disabled
in manual mode and enabled in all other processing modes.
| Time condition state | Meaning |
|---|---|
| Pending | The current time is before the start time of the condition and no system observation is necessary. |
| Observing and enabled | The current time is after the observation
start time and before the start time of the condition. The time condition
is enabled, and one or more workload conditions or utilization conditions are defined that require
systems to be observed. Systems that are referenced by associated
workload conditions or utilization
conditions are contacted to get performance information for
further processing. |
| Observing and disabled | The current time is after the observation start time and before the start time of the condition. The policy is enabled but the time condition is disabled. |
| Active and enabled | The current time is after the start time and before the deadline of the condition, and the time condition is enabled. The Provisioning Manager may change the managed capacity based on the provisioning condition that contains the time condition. |
| Active and disabled | The current time is after the start time and before the deadline of the condition. The policy is enabled but the time condition is disabled. The managed capacity cannot be changed by the Provisioning Manager based on the provisioning condition that contains the time condition. |
| Drained and enabled | The current time is after the deadline and before the end time of the condition; the time condition is enabled. The Provisioning Manager cannot change the managed capacity but can maintain the current managed capacity based on the provisioning condition that contains the time condition. |
| Drained and disabled | The current time is after the deadline and before the end time of the condition. The policy is enabled but the time condition is disabled. The managed capacity cannot be changed by the Provisioning Manager based on the provisioning condition that contains the time condition. |
| Inactive | The current time is after the end time of the condition; for recurring time conditions the current time is after the end time of the last selected day of the week between the start date and the end date. The managed capacity cannot be changed by the Provisioning Manager based on the provisioning condition that contains the time condition. |
