Administer Host Groups › Ensuring Efficient Processing of Host Group References

Ensuring Efficient Processing of Host Group References

This topic, which is relevant to content designers, is for administrator information.

During process design, content designers specify execution settings for each operator. The following example shows a partial dialog with the Target field and the Match target in Host Groups only check box.

When the Target field contains a touchpoint name, a proxy touchpoint name, or an agent ID, clear the Match target in Host Groups only check box.

When the Target field contains an IP address of a specific host, select the Match target in Host Groups only. Specifying an IP address or a host name in the Target field is valid only if a host group in the current environment references the corresponding host.

Important! If a process is destined for export in a folder as a content package, do not enter an IP address in the Target field. Rather, enter a dataset name that contains the IP address. Also:

• Select Target is a calculated expression.
• Select the Match target in Host Groups only. A dataset that references an IP address is valid if a host group in the current environment references the corresponding host.

To understand the purpose of this check box, consider the case where:

• The Target field has the entry some_host, where the entry is the host name of a host in a host group.
• The Match target in Host Groups only check box is cleared.

The runtime processing evaluates and processes the Target entry in the following sequence:

1. If the entry is a touchpoint name, runs on the host with the agent associated with the touchpoint.
2. If the entry is a proxy touchpoint name, runs on the host with the SSH connection to the agent associated with the proxy touchpoint.
3. If the entry is an agent ID, runs on the host with this agent ID.
4. If the entry is an IP address or a host name that a host group references, runs on that host.

   Note: The operator fails if you select the Match target in Host Groups only check box when the specified target is not part of a host group. The operator fails even if the target is a valid touchpoint name, proxy touchpoint name, or agent ID.
