With OpenInsight 9.2 now only a few short weeks away, there is news of yet more enhancements that will benefit your application and clients.
This time it is news of the OECGI3 executable that is being delivered within the new release. OECGI3 will support Failover and Load Balancing modes, making OECGI3 a more robust connection object which allows for extra capacity and/or redundancy to be added to a web application. A new OECGI3 registry setting, MultipleServers, controls whether OECGI3 operates in Failover (0) or Load Balancing Mode (1).
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 the SYSDOWNPAGE page is returned.
In Load Balancing mode, you supply OECGI3 with a list of ServerURL’s and ServerPort’s 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.
