Quantitative Resource management

A quantitative resource represents a measure that can be quantified such as percentage of CPU, megabytes of storage, or number of tape drives. It provides the ability to avoid overwhelming the physical and logical resources in an environment by limiting the number of jobs that use the same resource at the same time.

There are 2 parts to the process:

• From the Tools domain, in the Quantitative Resource window, you define the total quantity of Quantitative Resources for relevant Control-M/Servers.
• In the Job Properties, you define how much of that resource should be used in the jobs running on that Control-M/Server. To define a quantitative resource for a job, see Allocating a quantitative resource.

EXAMPLE: Control-M has three tape drives available. A job called BKP_Tallies requires one tape drive. To enable Control-M to handle this correctly, do the following:

• Using the Quantitative Resources window in the Tools domain, define the quantitative resource TapeDr having a quantity of 3.
• In Job Properties, when defining the job BKP_Tallies, specify 1 of TapeDr.

Whenever a job using TapeDr is submitted, Control-M drops the currently available quantity of the resource by the quantity the job uses, until the job ends. Control-M only submits BKP_Tallies if there is at least one TapeDr available.

When a Quantitative Resource is specified for a job, Control-M determines whether a sufficient quantity of the specified resource is available is before submitting the job. When the job is submitted, the specified quantity of resource is assigned to that job and is not available to other jobs. When the job finishes executing, the resource is made available to other jobs. For more information, see Quantitative Resources in Parameters.

In the Quantitative Resources window you can view the following:

• All the quantitative resources that currently exist or are in use in the production environment.
• Create a quantitative resource for a Control-M/Server as described in Creating a quantitative resource.
• Filter the display criteria
• The total number of quantitative resources that are being used
• View the following Types that you create:
  • Defined: Indicates information about the resource. Only a single definition entity exists per resource. This entity is added when you define a new Quantitative Resource.
  • In Use: Indicates that the resource is being used by a job. An In Use entry exists for each job that is currently using the resource.
  • Requested: Indicates that the resource has been requested by a critical job.
