Agent Management

Agents submit jobs for execution on the host computer, monitor jobs, and perform post-processing analysis of completed jobs. The job completion status and the post-processing analysis results are transmitted back to the Server.

You can install multiple Agents that are managed by a Control-M/Server. Jobs are assigned to an Agent name that identifies the host.

If the Agent is installed on Linux, BMC recommends you use non-root mode. For more information, see set_agent_mode.

In the Configuration domain, you can install, monitor, search, and manage Agents in your environment.

The following describes the specific actions you can perform on an Agent:

Add: Adds an Agent on your environment, as described in Adding an Agent.
Edit: Enables you to configure the following Agent parameters, as described in Configuring Agent Parameters.
Ping: Tests the connectivity to the Agent.
Recycle: Shuts down and starts up the Agent.
Disable: Disables all Agent actions.
Delete: Deletes the Agent from your environment. To fully remove it, you must uninstall the Agent from the host.

Adding an Agent

This procedure describes how to add an Agent component, which enables you to connect it to a self-hosted Control-M/Server via specific communication parameters. After you add the Agent, you can use the Control-M/Server to run jobs on this Agent. You can define and run jobs on the Agent after you add it.

Agent General Parameters

The following table describes Agent General parameters.

Parameter	Description
Server	Defines the name of the Server that sends job requests to the Agent. You cannot modify this parameter.
Agent Name	Defines the name of the host where the Agent is installed. You cannot modify this parameter. The Agent name is defined during the Agent installation, and it cannot be changed afterwards. Latin-1 special characters are not supported.
Tag	Defines a logical name that is used to label specific Agents into a group with a specific authorization level. You can apply a specific tag to an Agent, as described in Installing an Agent, or you can define your own tag with the asterisk character if you have the correct permissions.

Parameter

Description

Server

Defines the name of the Server that sends job requests to the Agent.

You cannot modify this parameter.

Agent Name

Defines the name of the host where the Agent is installed.

You cannot modify this parameter. The Agent name is defined during the Agent installation, and it cannot be changed afterwards.

Latin-1 special characters are not supported.

Tag

Defines a logical name that is used to label specific Agents into a group with a specific authorization level. You can apply a specific tag to an Agent, as described in Installing an Agent, or you can define your own tag with the asterisk character if you have the correct permissions.

Communication Parameters

The following table describes the Agent Communication parameters:

Field	Description
Agent to Server Port Number	Determines the port number between 1024 and 65535 that receives data from the Agent computer. Verify that this port is not used for any other purpose. This value must match the Agent-to-Server Port Number in Control-M/Server. The value is the COMTIMOUT communication Job-tracking timeout in seconds. Valid Values: Between 1024 and 65535 inclusive Default: 7005 7005/30 Increasing the Timeout value reduces agent performance.
Primary Server	Defines the hostname of the computer where the current Control-M/Server submits Jobs to the Agent.
Authorized Servers	Defines a list of backup servers which can replace the primary server if it fails. The Agent only accepts requests from servers on this list. You cannot submit Jobs to the same Agent if there is more than one active Control-M/Server. Another Agent instance must be installed with unique ports to support this configuration or Job status updates corrupt.
Check Interval	Determines the number of seconds between status checks for each Agent that communicates with the Control-M/Server. If you decrease the default value, it might impact Control-M/Server performance. Default: 7,200 (2 hours)
Retry Interval	Determines the number of seconds between attempts to communicate with an Agent computer whose status is Unavailable. If you decrease the default value, it might impact Control-M/Server performance. Default: 90
Unavailability Shout Urgency	Defines the urgency level of a message sent with high priority when an Agent has an Unavailable status. Urgent messages are sent with a special indication so that the recipient of the message is aware of the urgency.
Communication Timeout	Determines the maximum number of seconds that the Control-M/Server attempts to connect to the Agent before the Agent is set to Unavailable. If you decrease the default value, it impact Control-M/Server performance. Default: 120
TCP/IP Timeout	Determines the timeout used by the Agent when listening on the Server to agent port number before timing out and performing housekeeping tasks
Maximum Retries	Determines the number of times the Control-M/Server attempts to connect to the Agent before the Agent is set to Unavailable.
Logical Agent Name	Defines a logical or alias name for the Agent. If you have more than one Agent on the same host that connects to the same Control-M/Server, you must use this parameter to uniquely identify each Agent. The value must be the same as the value in the Control-M/Server computer. The logical name is used when the Agent initiates the communication to the Control-M/Server with the output from Agent utilities and in messages sent to the Control-M/Server.
Listen to Network Interface	Determines which network interface the Agent is listening on. It can be set to a specific hostname or IP address so that the Agent port is not opened in the other interfaces.
Secure Socket Layer	Determines whether SSL is used to encrypt the communication between Control-M/Server and the Agent.

Persistent Connection Parameters

The following table describes the Persistent Connection parameters:

Field	Description
Persistent Connection	Determines whether to connect to a specific agent with either a persistent or transient connection. The connection between Control-M/Server and Agent is constant and can be initiated by both. When the Agent starts up, the Agent Router process is started and acts as a broker between the other Agent components and Control-M/Server. The Agent Router process allows Control-M/Server to maintain a constant connection with the Agent. However, when Control-M/Server sits behind a firewall, the Agent Router cannot initiate the connection with Control-M/Server. After the Control-M/Server creates the connection to the Agent Router, the Agent Tracker and Agent Utilities processes use this connection to communicate with Control-M/Server.
Maximum Disconnect Time	Determines the maximum number of seconds that the Control-M/Server allows an agent to be disconnected before it initiates a session. This parameter is relevant only if the Allow Agent to Initiate a Session parameter on the agent is set to NO. Valid Values: 30–86,400 Default: 300
Session Idle Timeout	Determines the maximum number of seconds that a session can be idle before Control-M/Server terminates it. Valid Values: 30–86,400 Default: 900
Allow Agent Disconnection	Determines if the current connection to this Agent can be disconnected when the maximum number of concurrent sessions is reached. Allowing a persistent connection on a Agent to disconnect requires the connection to be reestablished before communication with the Agent can continue. If you run time-sensitive jobs on the Agent, you might want to select No. Default: Yes
Allow Agent to Initiate a Session	Determines if the Agent can open a connection to the Control-M/Server when working in Persistent Connection mode. If the Agent is outside a firewall and the Agent to Server port is blocked, set this parameter to No. Default: Yes
