Connect to different clusters with the same client

  • This section applies to Symphony grid, but not Symphony DE.

  • There is no firewall that prohibits the client from establishing communication ports to management hosts in the clusters.

  • All clusters to which the client is connecting have the same Symphony version and same patch level .

  • All cluster configuration files have the same security plugin configured. The default cluster configuration file %EGO_CONFDIR%\ego.conf on Windows and $EGO_CONFDIR/ego.conf on Linux.

You want a client to connect to the same application in a different cluster and to be able to submit work there. This is useful when you have several clusters and you want to take advantage of idle CPUs.

In your client code, when creating a connection, use the connection method that allows you to specify a connection file name or master host list.

Test your connection to multiple clusters. Note that code for this feature can be tested in Symphony DE, but you will only be able to connect to multiple clusters once in the grid environment.
