HA Requirements
To enable HA mode, the following requirements must be met:
-
All Platform Servers in the HA Cluster must define the same
HACyberMgrPrimary
andHACyberMgrSecondary
parameters in theconfig.txt
in the same order. -
Each Platform Server must run a local CyberMgr daemon.
-
All PSU in the HA cluster must have access to the same shared Config directory.
-
All PSU must have read/write access to the files being transferred.
-
All PSU must have read/write access to the shared directories where the PQF, Transnum, and Log.txt files are located.
-
Firewalls must allow communication to the Primary and Secondary
CyberMgr
ports. -
Config files should be in a common shared directory and each system in the cluster should have read/write access to the config file directory and files.
-
Platform Servers in a HA cluster should be the same endian (little endian or big endian) server type. For example, You should not mix AIX (big endian) and Linux x86 (little endian) servers in the same cluster.
-
More than two Platform Servers instances can be in the same cluster. Each Platform server must run a local
CyberMgr
even if they point toHACyberMgrPrimary
andHACyberMgrSecondary
on different machines.
The end result:
The PS client thinks that two (or more) PSU servers appear to be one PSU Server
