There are two types of services in Domain Service Manager: Once open in a web browser it prompts for administrator login. Properties of the domain Click on the properties menu in the admin page to view the properties of the domain. After completion of execution, session log and workflow log is generated.

When we execute a workflow, the integration service receives a notification to execute the workflow. A single repository service handles exclusively only one repository. In a domain, you will also find a gateway node. Powercenter designer, workflow manager, a repository manager, and workflow monitor are the main client tools.

Database host — Hostname of the machine on which domain is configured. Informatica Domain is the fundamental administrative unit in Informatica tool. These properties can be modified based upon requirement. There are three Informatica Client tools available in Informatica Powercenter. When any object is saved in Informatica, it is checked whether its syntax and properties are valid or not, and the object is marked with the status accordingly.

What do you mean by Enterprise Data Basicss On the main window, it shows the status of those services, whether those are up or down. These services run on different nodes based upon the configuration.

Repository Service The repository service maintains the connections from Powercenter clients to the PowerCenter repository.

Objects created in the repository can have following three state Valid: It also runs application services on the nodes as well as manages users and groups. These database systems are generally owned by other applications which create and maintain this data. A flat file can be a comma separated file, a tab delimited file or fixed width file.

Integration Service Integration service is the executing engine for the Informatica, in other words, this is the entity which executes the tasks that we create in Informatica. Dispatch Mode basiics It is the policy used by the load balancer to dispatch tasks to various nodes.

To use the flat file in Informatica, its definitions must be imported similar to as we do for relational tables. The password is set during the Informatica installation. The console can be launched using web browsers. For example in a mapping if you are using a reusable transformation, and this transformation object becomes invalid then the mapping will be marked as impacted. Node is a logical representation of a machine inside the domain. Database type — The type of database on which domain is configured.

The mappings and objects that we create in these client tools are saved in the Informatica repository which resides on the Informatica server. They are Informatica Designer Workflow Monitor Workflow Manager These clients can access to the repository using repository service only.

Flat file targets are generated on the Informatica server machine, which can be transferred later on using ftp. The domain configuration can be done using the Informatica admin console. We import source definitions from the source and then connect to it to fetch the source data in our mappings. It is a collection of nodes and services.

Informatica supports any of the code pages like ascii or Unicode. It is a separate multi-threaded process, and it fetches, inserts and updates the metadata inside the repository. Informatica instructs the integration service to execute the workflow. These objects can be used in the execution of workflows. This service is responsible for loading data into the target systems The integration service also combines data from different sources For example, it can combine data from an oracle table and a flat file source.

It is also responsible for maintaining consistency inside the repository metadata. This service is responsible for loading data into the target systems. There can be different types of sources and can be located at multiple locations.

Restart Period — It is the maximum number of seconds the domain spends to restart a service. The input to our mappings in Informatica is called source system. So, in summary, Informatica integration service is a process residing on the Informatica server waiting for tasks to be assigned opwercenter the execution.

It consists of database tables that store metadata.

Flat Files – Flat files are most common data sources after relational databases in Informatica. Based upon your powercsnter the target system can be a relational or flat file system.

With the version control feature, you can maintain different versions of the same object. You can enable version control in the repository. Key properties of the domain are Resilience timeout — If any of the integration service or repository services goes down then resilience timeout is the no of seconds the application service tries to connect to those services.

You can have multiple nodes in a domain.
