Informatica Architecture Tutorial. In this tutorial- you will learn. Informatica Domain. PowerCenter Repository. Domain Configuration. Properties. In this tutorial,you will learn how Informatica does various activities like data cleansing, data Tutorial, How to Install Informatica PowerCenter. This Informatica Tutorial blog will explain Informatica PowerCenter in detail, informatica architecture and how to create domain in Informatica.
A flat file can be a comma separated file, powercentr tab delimited file or fixed width file. So the client tools must have network connectivity to the server. Flat Files – Flat files are most common data sources after relational databases in Informatica. Integration service starts execution of the tasks inside the workflow. Informatica Domain is the fundamental administrative unit in Informatica tool.

The domain configuration can be done using the Informatica admin console. Service manager manages informahica operations like authentication, authorization, and logging. These objects can be used in the execution of workflows. We import source definitions from the source and then connect to it to fetch the source data in our mappings.
Objects created in powercentef repository can have following three state Valid: Accounting Business Analyst Cloud Computing. There are two types of services in Domain Service Manager: 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. The mappings and objects that we create in these client tools are saved in the Informatica repository which resides on the Informatica server.
It also runs application services on the nodes as well as manages users and basocs.

There can be different types of sources and can be located at multiple locations. You can enable version control in the repository. Relational — these types of sources are database system tables. Invalid objects are those who does not adhere to the standard or rules specified. Impacted objects are those whose child objects ihformatica invalid.
Database type — The type of database on which domain is configured. When we execute a workflow, the integration service receives a notification to execute the workflow. Flat file targets are generated on the Informatica server machine, which can be transferred later on using ftp.
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. 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. It is a separate multi-threaded process, and it fetches, inserts and updates the metadata inside the repository.
In a domain, you will also find a gateway node. With the version control feature, you can maintain different versions of the same object.
Database host — Hostname of the machine on which domain is configured. Node is required to run services and processes for Informatica. These properties can be modified based upon requirement. Powercenteg supports any of the code pages like ascii or Unicode. The gateway node is responsible for receiving requests from different client tools and routing those requests to different nodes and services.
This is how it works A user executes a workflow Informatica instructs the integration service to execute the workflow The integration service reads workflow details from the repository Integration service starts execution of the tasks inside the workflow Once execution is complete, the status of the task is updated i.
Repository Service The repository service maintains the connections from Powercenter powecenter to the PowerCenter repository.
Then the service reads the task details from the repository and proceeds with powercwnter execution. To manage a repository there exists an Informatica service called Repository Service.
Further, this nodes and services can be categorized into folders and sub-folders based on the administration requirement. These database systems are generally owned by other applications which create and maintain this data.
Informatica Domain is the fundamental administrative unit in Informatica tool It is a collection of nodes and services. The repository services use locks on the objects, so multiple users cannot modify the same object same time.
A single repository service handles exclusively only one repository. Based upon your requirement the target system can be a relational or flat file system. Restart Period — It is the maximum number of seconds the domain spends to restart a service.
