Did You Know – OECGI3 Failover & Load Balancing.


Did you know……That OECGI3 supports Failover and Load Balancing modes.  These modes make OECGI3 a more robust connection object and allows for extra capacity and/or redundancy to be added to a web application.  The OECGI3 registry setting, MultipleServers, controls whether OECGI3 operates in Failover or Load Balancing mode.

MultipleServers = 0 sets Failover mode
MultipleServers = 1 sets Load Balancing mode

Multiple URL’s and Port’s are entered as comma delimited fields into the ServerURL and ServerPort registry settings.

ServerURL = 192.168.0.1,192.168.0.2
ServerPort = 8088,8089

In Failover mode, you supply OECGI3 with a list of ServerURL’s and ServerPort’s that are available.  OECGI3 attempts to connect to the first ServerURL/ServerPort in the list.  If the connection is unsuccessful then OECGI3 will continue on to the next ServerURL/ServerPort in the list until a successful connection is made.  If all connection attempts fail, then OECGI3 will return the SYSDOWNPAGE page.

In Load Balancing mode, you supply OECGI3 with a list of ServerURLs and ServerPorts that are available.  OECGI3 will randomly choose a ServerURL/ServerPort from the list available, and then attempt to connect to that server.  If the connection fails, OECGI3 will move to the next ServerURL/ServerPort in the list, looping through the list until it is back at the originally selected URL/Port combination, at which point OECGI3 will return the SYSDOWNPAGE page.
