RemoteGroup agent
■
■
■
The remote cluster is a two-node cluster, where remote1 and remote2 are the
names of the two remote nodes.
LocGrp is the local service group that contains the WebRes resource (for
example: Apache, etc.) configured for the Web-server that runs in the local
cluster.
RemGrp is the remote service group that contains the DBRes resource (for
example: MySQL or Oracle, etc.) configured for the database in the remote
cluster.
The database resource (DBRes) needs to come online before the Web server
resource (WebRes) comes online. You can use the RemoteGroup agent to establish
this inter-cluster application dependency.
To configure the remotegroup agent for this setup
1 Create a RemoteGroup resource (RGRes) in the local service group (LocGrp)
for monitoring or managing the DBRes resource in the remote cluster.
2 Link the resources such that the WebRes resource depends on the RGRes
resource.
3 Set the attributes for the RemoteGroup resource (RGRes) as follows:
■

■
■
■
IpAddress—Set to the IP address or DNS name of a node in the remote
cluster. For this example, the value is remote1. You can also set this value
as remote2 (second node in the remote cluster).
The RemoteGroup agent keeps a list of remote nodes (remote1, remote2)
on the local node. The IP address that you specify should be reachable the
first time the RemoteGroup agent tries to communicate to the remote
cluster. In case the specified IP address is not reachable after the first
communication, the RemoteGroup agent talks to the second remote node
to retrieve the state of RemGrp.
GroupName—Set the value to RemGrp (the remote service group).
VCSSysName—Set appropriate values so as to establish a one-to-one
mapping between the systems in the local and remote clusters. RGRes
will completely manage the remote service group (RemGrp) that contains
the DBRes resource. Make this a local attribute for the RGRes.
ControlMode—Set the value to OnOff.
Username—Set the value to user_admin. The user needs to have
administrative privileges for RemGrp.
Password—Password for user_admin. You must encrypt the password
using the VCS Encrypt command. See the VCS Administrator's Guide for
more information on the VCS Encrypt utility.
