2.2 Install Caché
Install Caché on the first node. When the installation process asks for an instance name, use
the same name as you used for the cluster service.
When the installation completes, use the System Management Portal to make the following
configuration changes. If you are installing multiple instances of Caché, do this after each
installation, not when they are all complete.
1. Verify unique port numbers — The installation procedure assigns unique port numbers
to multiple instances on the same machine. From the [Home] > [Configuration] > [Memory
and Startup] page, verify the instance has a unique SuperServer Port Number.
2. Update license managers — From the [Home] > [Licensing] page, click License Server.
Click Edit in the local server row and replace the Name/IP Address with the name (or IP
address) of the current node. Do not use the virtual IP address; use the real IP address
(or DNS name). Click Save.
Add a second license manager (click Add) and enter the IP address or DNS name of the
other cluster member. Again, use the real name or IP address, not the virtual IP address
for the cluster. Click Save.
3. Configure ECP — If you are setting up an active-active cluster and using ECP between
the instances of Caché, you may configure that now or wait until later. Navigate to the
[Home] > [Configuration] > [ECP Settings] page. Click Add Remote Data Server and define
the other instance of Caché as a server to this one. For clarity, choose the cluster instance
name for the name of the ECP data server. The portal Create a Database wizard uses this
name to refer to the remote node. Use the virtual IP address that you assigned to that
instance for the Host Name, not the real IP address or the real DNS name.
4. Increase maximum number of ECP data and application servers — If there are other
ECP data servers or application servers in your network, increase the maximum settings
as appropriate for your system. Navigate to the [Home] > [Configuration] > [ECP Settings]
page. Under This System as an ECP Data Server, increase Maximum number of application
servers and under This System as an ECP Application Server, increase Maximum number
of data servers. Enable the ECP service if it is disabled.
See the “Configuring Distributed Systems” chapter of the Caché Distributed Data Manage-
ment Guide for more information on configuring ECP.
Stop this running instance of Caché and repeat the process to install and configure all additional
instances of Caché on this node.
