GROUPS Section

This section provides information about server groups, and must have at least one server group defined in it. A server group entry provides a logical name for a collection of servers and/or services on a machine. The logical name is used as the value of the SRVGRP parameter in the SERVERS section to identify a server as part of this group. SRVGRP is also used in the SERVICES section to identify a particular instance of a service with its occurrences in the group. Other GROUPS parameters associate this group with a specific resource manager instance (for example, the employee database). Lines within the GROUPS section have the form: 

GROUPNAMErequired parameters [optional parameters]

where GROUPNAME specifies the logical name (string_value) of the group. The group name must be unique within all group names in the GROUPS section andLMID values in the MACHINES section. The group name cannot contain an asterisk(*), comma, or colon, and must be 30 characters or less.

A GROUPS entry is required for the group that includes the Jolt Server Listener (JSL). Make the GROUPS entry as follows:

  1. The group name is selected by the application, for example: JSLGRP and JREPGRP.
  2. Specify the same identifiers given as the value of the LMID parameter in the MACHINES section.
  3. Specify the value of the GRPNO between 1 and 30,000 in the *GROUPS section.

Note:

Ensure that Resource Managers are not assigned as a default value for all groups in the GROUPS section of your UBBCONFIG file. Making Resource Managers the default value assigns a Resource Manager to the JSL and you receive an error during tmboot. In the SERVERS section, default values for RESTART, MAXGEN, etc., are acceptable defaults for the JSL.
