You scale the gateway by installing an identical gateway on several application servers to create a scaling group, then using a plug-in to the front-end HTTP server to balance the load across the group.
Before you begin
If any (or
all) of the application servers in your scaling group are hosted on nodes
that are members of a deployment manager cell, the cell cannot safely also
contain other gateway servers that are not part of the scaling group.
In the z/OS environment,
the gateway technology preview only operates in an application server that
has exactly one servant process instance.
Therefore the process described here is the only way to achieve load balancing
for the gateway technology preview on z/OS.
Why and when to perform this task
You configure an instance of the gateway that is separate from the scaling group, then maintain this gateway as the source configuration for every gateway in the group. You use the back up and restore options to save the source configuration as a Shared configuration, then restore the saved configuration to every gateway in the group.
To scale the gateway using unlocked configuration deployment, complete the following steps:
