22.6 Messenger Clustering Quick Checklist
‰ Plan your clustered Messenger system.
See Section 22.1, “Planning Your Messenger System in a Linux Cluster,” on page 229 .
‰ Create your Messenger system and install the Messenger agents.
4) Nodes in Cluster
Š
FIle system type
Š
Device name
Š
Mount point
List the nodes that are part of the cluster that will include
Messenger. Also list technical information, including file system
type (
reiserfs
,
ext3
, etc.), device name (
sda2
,
hda1
, etc.),
and mount point directory (
/mnt
,
/mail
, etc.) in use on the
nodes the cluster. You need this information as you create load
and unload scripts for the Messenger agents.
For more information, see Section 13.1, “Installing Novell
Cluster Services on Linux,” on page 134 .
5) Shared Partitions in Cluster: List the shared partitions that are available for use in your
Messenger system.
For more information, see Section 13.1, “Installing Novell
Cluster Services on Linux,” on page 134 .
6) Messenger Partition for Messaging
Agent:
Secondary IP address:
Use Same Partition for Archive Agent?
Š
Yes
Š
No
The Messaging Agent software is installed on each node in its
failover list but it does use a shared partition to store its log
files, temporary files, and queue directories. Specify the name
of the shared partition in the your cluster that the Messaging
Agent can use for these purposes. also specify the secondary
IP address of that shared partition.
For more information, see “Selecting the Messenger Volume”
on page 121 .
7) Messenger Partition for Archive
Agent?
Secondary IP Address:
In addition to the data storage needs of the Messaging Agent,
the Archive Agent can be configured to store all instant
message conversations. It is possible that this might consume
a large quantity of disk space. If so, you could choose to use a
separate shared partition for the Archive Agent.
For more information, see “Selecting the Messenger Volume”
on page 121 .
8) Failover List for Messenger Agents: List other nodes in the cluster where the Messenger agents
can fail over. You might want to have the same nodes on the
both agents’ lists or have separate lists for each agent. It
depends on the loads that each agent will be carrying.
For more information, see “Determining an Appropriate
Failover Path for the Messenger Volume” on page 121 .
9) Mount Point for Shared Storage: Specify the mount point directory where the shared resource is
mounted to the cluster node where the Messenger Agents run.
For more information, see Section 22.1.4, “Determining Cluster
Resource Information for the Messenger Agents,” on
page 230
