High Availability Considerations
Platform Server High Availability (HA) allows two or more Platform Servers to act as a single Platform Server. When using HA mode, Platform Servers are set up to use a shared directory for the log and configuration files.
Here are some items that should be considered when implementing HA mode:
-
You can migrate any PS server to HA mode by either running the
install
script or by running thehainstall
script. -
When you run the
install
script, you can install a new PSU 8.1.1 or upgrade your existing version to version 8.1.1, and at the end of installation you are asked whether or not you want to proceed migrating to the HA mode right away. -
You can upgrade an existing PSU version 8.1.1 from a regular mode to HA mode at any time by running the
hainstall
script from the$CFROOT/bin
folder.
