Service Manager

The Service Manager is a service that manages all domain operations. It runs within Informatica Services. It runs as a service on Windows and as a daemon on UNIX. When you start Informatica Services, you start the Service Manager. The Service Manager runs on each node. If the Service Manager is not running, the node is not available.

The Service Manager runs on all nodes in the domain to support the application services and the domain:

  Application service support. The Service Manager on each node starts application services configured to run on that node. It starts and stops services and service processes based on requests from clients. It also directs service requests to application services. The Service Manager uses TCP/IP to communicate with the application services.

  Domain support. The Service Manager performs functions on each node to support the domain. The functions that the Service Manager performs on a node depend on the type of node. For example, the Service Manager running on the master gateway node performs all domain functions on that node. The Service Manager running on any other node performs some domain functions on that node.

Table 1-1 describes the domain functions that the Service Manager performs:
