Gateway Configuration

Gateway Configuration

A domain requires at least one node configured as a gateway node. You can configure multiple gateway nodes as backups.
One gateway node in the domain serves as the master gateway node for the domain. The Service Manager on the master gateway node accepts service requests and manages the domain and services in the domain. If the domain has one gateway node and it becomes unavailable, the domain cannot accept service requests. If the domain has multiple gateway nodes and the master gateway node becomes unavailable, the Service Managers on the other gateway nodes elect a new master gateway node. The new master gateway node accepts service requests. Only one gateway node can be the master gateway node at any particular time.
You can make the following changes to the gateway configuration for the domain:
Convert a worker node to serve as a gateway node.
You can convert a worker node to serve as a gateway node if the worker node is running and has the service role enabled. When you convert a worker node to a gateway node, you must specify the log directory for the node. If you have multiple gateway nodes, configure all gateway nodes to write log files to the same directory on a shared disk.
After you convert a worker node to a gateway node, the Service Manager on the master gateway node writes the domain configuration database connection to the nodemeta.xml file of the new gateway node.
Convert a gateway node to serve as a worker node.
You can convert a gateway node to serve as a worker node if another node in the domain is configured as a gateway node.
If you convert a master gateway node to serve as a worker node, you must restart the node to make the Service Managers elect a new master gateway node. If you do not restart the node, the node continues as the master gateway node until you restart the node or the node becomes unavailable.
