RMS enables you to define a set of servers as a logical group and monitor the group as a single entity. You can have many logical groups in your replication environment. The servers in a group can belong to different logical groups. However, all servers in one logical group must be of the same type. For example, you can have one logical group of all Replication Servers and another for all Adaptive Servers. When you issue any command to a group, it affects all the servers contained in this logical group.
You can delete logical groups. When you delete a logical group, only the group is deleted, not the servers within the group.
RMS also returns a rollup status for each group or each server in a group. Roll-up status shows the lowest status reported, for example, if any server in a group is not UP, then the group status is reported as SUSPECT.
RMS API commands to manage logical groups are:
create group – defines a logical group of servers.
delete group – deletes a logical group that was added using the create group command.
get group – returns a result set that contains either a list of the groups and a rollup status for each group or for each server.
For detailed information about these APIs, see Chapter 9, “Replication Monitoring Services API,” in the Replication Server Reference Manual.
