You can apply updates to the Presence Server product,
like interim fixes and fix packs, without disruption to normal processing
when the product is deployed in a horizontal WebSphere cluster. This
feature is known as a rollout update. In a vertical cluster,
the same process is used to apply updates, but there will be an interval
during which Presence Server is
not available for use.
Before you begin
The EAR file for the Presence Server update
you are installing, for example was_root/installableApps/presence/IBMWebSpherePresenceServer.ear,
must exist either on the local computer or on the deployment manager
node.
Refer to the Readme file, which is included with every
update or fix, for additional prerequisites.
About this task
Note that continuous availability is possible only in
clusters that have a horizontal scaling topology–that is, cluster
members exist on multiple WebSphere nodes. In the case of a vertical
configuration (where all cluster members exist on the same physical
computer), you should follow the same steps to perform updates. However,
the Presence Server application
will be taken offline while you are applying the updates.
To
install updates to the Presence Server product,
follow these steps:
- Log in to the Integrated Solutions Console:
- Open a browser and navigate to the following
URL: https://host_name:port/ibm/console.
Where:
- host_name is the fully qualified host name
of the server where the application or the network deployment manager
is deployed.
- port is the secured port used to access the
console. The default port is 9043.
Note: The default unsecured port is 9060.
If you use 9060, you must have "http" instead of "https" in the URL.
- Enter an administrator user ID and password.
- Click Log in.
- Click .
Note: If you are using WebSphere® Application Server version 6.1.0.x, reach
this window by clicking .
- Select the Presence Server check
box and click Rollout Update.
Note: In WebSphere Application Server version 6.1.0.x,
select the Presence Server check
box and click Update.
- Browse to the EAR file for the Presence Server update
you are installing, for example was_root/installableApps/presence/IBMWebSpherePresenceServer.ear.
- Optional: Make any desired changes to the default
settings, clicking Next to navigate through
the lists of options.
- Click Finish to complete the update. When the update is complete, the following message displays: Application
Presence Server installed successfully.
- Click the Rollout Update link.
- When all cluster members have completed the synchronization
phase, click Continue.
