Three types of runtime criteria require Control-M to monitor the existence of conditions and the availability of resources system-wide. These conditions and resources are mentioned briefly below and are discussed in greater detail in Control-M Concepts:
Table 4 Conditions and Resources
Condition or Resource |
Description |
|---|---|
Quantitative resources |
Quantity of a resource required by the job. For example, a job may require two tape drives. |
Control resources |
Mode (exclusive or shared) in which a resource is required. For example, a backup job may require exclusive access to a specified data set. |
Prerequisite conditions |
User-defined conditions that must exist before a job is submitted. A major use of prerequisite conditions is to establish job dependencies. |
The condition and resource requirements of a job are defined in the job scheduling definition.
Prerequisite conditions are tracked by the IOA Conditions file. Existing and available Quantitative resources and Control resources are tracked by the Control-M Resources file. Prior to version 6.0.00, conditions and resources were stored in a single file, the Conditions/Resources file.
When the prerequisite conditions and resources required by a job are available, the job can be submitted by the monitor, if all other runtime scheduling criteria are satisfied.
