Service Manager

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 in the domain. 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 domain and 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 and role of the 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 type of node performs limited domain functions on that node.
  • Application service support. When a node has the service role, the Service Manager 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.
The following table describes the domain functions that the Service Manager performs:
Function
Description
Alert Management
The Service Manager sends alerts to subscribed users. You subscribe to alerts to receive notification for node failure and master gateway election on the domain, and for service process failover for services on the domain. When you subscribe to alerts, you receive notification emails.
Alert management occurs on the master gateway node.
Authentication
The Service Manager authenticates users who log in to application clients.
Authentication occurs on the master gateway node.
Authorization
The Service Manager authorizes user requests for domain objects based on the privileges, roles, and permissions assigned to the user. Requests for domain objects can come from the Administrator tool.
Domain authorization occurs on the master gateway node.
Container Management
When a node has the compute role, the Service Manager manages the containers on the node. A container is an allocation of memory and CPU resources. An application service uses the container to remotely perform computations on the node. For example, a Data Integration Service that runs on a grid can remotely run a mapping within a container on a node with the compute role.
Container management occurs on any node with the compute role.
Domain Configuration
The Service Manager manages the domain configuration metadata.
Domain configuration occurs on the master gateway node.
Node Configuration
The Service Manager manages node configuration metadata in the domain.
Node configuration occurs on all nodes in the domain.
Licensing
The Service Manager registers license information and verifies license information when you run application services.
Licensing occurs on the master gateway node.
Logging
The Service Manager provides accumulated log events from each service in the domain. To perform the logging function, the Service Manager runs a Log Manager and a Log Agent.
The Log Manager runs on the master gateway node. The Log Agent runs on all nodes where PowerCenter® Integration Service sessions and workflows run and where Data Integration Service jobs run.
User Management
The Service Manager manages the native and LDAP users and groups that can log in to application clients. It also manages the creation of roles and the assignment of roles and privileges to native and LDAP users and groups.
User management occurs on the master gateway node.
Monitoring
The Service Manager persists, updates, retrieves, and publishes run-time statistics for integration objects in the monitoring Model repository. The Service Manager stores the monitoring configuration details in the domain configuration repository.
Monitoring occurs on the master gateway node.
The following image shows where the Service Manager performs domain functions:
Node 1 is a master gateway node with the service role. The Service Manager on Node 1 performs all domain functions. Node 2 is a gateway node with both the service and compute roles. The Service Manager on Node 2 performs the container management and node configuration functions. Node 3 is a worker node with the compute role. The Service Manager on Node 3 performs the container management and node configuration functions.
