Job Scheduling in Control M
Control M is a popular workload automation tool that is widely used in the IT industry. One of the key features of Control M is its ability to schedule and execute batch processes. In this section, we will discuss how job scheduling works in Control M, and the various aspects of job scheduling that you need to be aware of.
Job Types
Control M supports several different types of jobs, each with its own unique characteristics and use cases. Some of the most commonly used job types in Control M include:
- Command jobs: These are simple jobs that execute a single command or script.
- File transfer jobs: These jobs are used to transfer files between different systems or servers.
- SAP jobs: These jobs are used to execute SAP transactions and reports.
- Database jobs: These jobs are used to execute SQL commands or stored procedures.
Job Properties
In Control M, each job is associated with a set of properties that define its behavior and characteristics. Some of the most important job properties that you need to be aware of include:
- Job name: This is a unique identifier for the job.
- Owner: This is the user who is responsible for the job.
- Application: This is the name of the application that the job is associated with.
- Resources: These are the resources that the job requires to run, such as CPU, memory, and disk space.
- Time window: This is the time period during which the job can be executed.
Job Flow
The flow of a job in Control M is defined by a set of conditions and dependencies. Each job can have one or more predecessors and successors, which determine the order in which the jobs are executed. In addition, you can define conditions that must be met before a job can be executed, such as the completion of another job or the availability of a specific resource.
Job Priorities
Control M allows you to assign priorities to jobs, which determine the order in which they are executed. Jobs with a higher priority are executed before jobs with a lower priority. This is useful when you have multiple jobs that need to be executed at the same time, but you want to ensure that certain jobs are given priority over others.
In conclusion, understanding how job scheduling works in Control M is essential for anyone who is working with this powerful workload automation tool. By familiarizing yourself with the different job types, properties, flow, and priorities, you can ensure that your batch processes are executed in a timely and efficient manner.
Working with Control M
When it comes to working with Control M, there are a few key concepts that you should be familiar with. These include in condition, prerequisite conditions, global conditions, and control resources.
In Condition
In condition is a feature in Control M that allows you to specify a condition that must be met before a job can be executed. This can be useful in situations where you need to ensure that certain criteria are met before a job can run. For example, you might use an in condition to ensure that a file is available before a job starts processing it.
Prerequisite Conditions
Prerequisite conditions are similar to in conditions, but they are used to specify conditions that must be met before a job can be added to the Control M schedule. This can be useful in situations where you need to ensure that certain criteria are met before a job can even be considered for execution. For example, you might use a prerequisite condition to ensure that a certain file exists before a job can be added to the schedule.
Global Conditions
Global conditions are conditions that apply to all jobs in a Control M environment. These conditions can be used to enforce policies or ensure that certain criteria are met across the board. For example, you might use a global condition to ensure that all jobs run during a certain time window or to enforce a maximum number of concurrent jobs.
Control Resources
Control resources are resources that are used by Control M to manage jobs. These resources can include things like databases, message queues, and file systems. Control resources can be configured to ensure that jobs are executed in a way that is consistent with your organization’s policies and procedures.
Overall, understanding these key concepts is essential for anyone who works with Control M. By mastering these concepts, you can ensure that your jobs are executed in a way that is consistent, reliable, and efficient.
Control M Servers and Agents
Server
Control M Server is the backbone of the Control M architecture. It is responsible for managing the job scheduling and monitoring the jobs execution. The server is installed on a dedicated machine, and it can manage multiple agents distributed across different physical locations. The server is responsible for storing job definitions, job schedules, and job logs. It is also responsible for communicating with the agents to execute the jobs.
Agent
Control M Agent is installed on the machine where the jobs are executed. The agent communicates with the server to receive job definitions and execute the jobs. The agent is responsible for monitoring the job execution and reporting the job status back to the server. The agent can execute jobs on the local machine or on remote machines.
Datacenter
Control M Datacenter is a collection of Control M components that work together to provide job scheduling and execution services. The datacenter consists of Control M Server, Database, and Control M Agents. The datacenter can be distributed across different physical locations to provide high availability and scalability.
Node
Control M Node is a logical entity that represents a machine or a group of machines. A node can have one or more agents installed on it. The node is used to group the agents based on their location or function. The node can be used to restrict the execution of jobs to specific machines or groups of machines.
Node Group
Control M Node Group is a logical entity that represents a group of nodes. The node group is used to group the nodes based on their location or function. The node group can be used to restrict the execution of jobs to specific groups of machines.
In summary, Control M Server and Agents are the key components of the Control M architecture. The server is responsible for managing the job scheduling and monitoring the jobs execution, while the agent is responsible for executing the jobs. The datacenter is a collection of Control M components that work together to provide job scheduling and execution services.
