Plan the Application Services
When you plan the Informatica domain, you also need to plan the application services that run in the domain. You create application services based on the license key generated for your organization.
When you plan the application services, you must account for the associated services that connect to the application service. You also must plan the relational databases that are required to create the application service. When you install Live Data Map, the installer creates the required application services. Optionally, you can also create the application services after you complete the installation.
Analyst Service Overview
The Analyst Service is an application service that runs the Analyst tool in the Informatica domain. The Analyst Service manages the connections between the service components and the users who log in to the Analyst tool.
The Analyst Service connects to a Data Integration Service that runs profiles, scorecards, and mapping specifications. The Analyst Service also connects to a Data Integration Service that runs workflows.
The Analyst Service connects to the Model Repository Service to identify a Model repository. The Analyst Service connects to a Search Service that enables and manages searches in the Analyst tool.
Additionally, the Analyst Service connects to the Analyst tool, a flat file cache directory to store uploaded flat files, and a business glossary export file directory.
You can use the Administrator tool to create and recycle an Analyst Service in the Informatica domain and to access the Analyst tool. When you recycle the Analyst Service, the Service Manager restarts the Analyst Service.
You can run more than one Analyst Service on the same node. You can associate a Model Repository Service with one Analyst Service. You can associate one Data Integration Service with more than one Analyst Service. The Analyst Service detects the associated Search Service based on the Model Repository Service assigned to the Analyst Service.
Data Integration Service Overview
The Data Integration Service is an application service in the Informatica domain that performs data integration tasks for Informatica Analyst and Informatica Developer.The Data Integration Service is an application service in the Informatica domain that performs data integration tasks for Informatica Developer. It also performs data integration tasks for external clients.
When you preview or run mappings, profiles, SQL data services, and web services in the Analyst tool or the Developer tool, the application client sends requests to the Data Integration Service to perform the data integration tasks. When you start a command from the command line or an external client to run mappings, SQL data services, web services, and workflows in an application, the command sends the request to the Data Integration Service.
When you preview or run mappings and profiles, the application client sends requests to the Data Integration Service to perform the data integration tasks. When you start a command from the command line or an external client to run mappings, the command sends the request to the Data Integration Service.
The Data Integration Service performs the following tasks:
- •Runs mappings and generates mapping previews in the Developer tool.
- •Runs profiles and generates previews for profiles in the Analyst tool and the Developer tool. Runs profiles and generates previews for profiles in the Developer tool.
- •Runs scorecards for the profiles in the Analyst tool and the Developer tool. Runs scorecards for the profiles in the Analyst tool and the Developer tool.
- •Runs SQL data services and web services in the Developer tool.
- •Runs mappings in a deployed application.
- •Runs workflows in a deployed application.
- •Caches data objects for mappings and SQL data services deployed in an application. Caches data objects for mappings deployed in an application.
- •Runs SQL queries that end users run against an SQL data service through a third-party JDBC or ODBC client tool.
- •Runs web service requests against a web service.
Create and configure a Data Integration Service in the Administrator tool. You can create one or more Data Integration Services on a node. Based on your license, the Data Integration Service can be highly available.
Model Repository Service
The Model Repository Service is an application service that manages the Model repository. The Model repository stores metadata created by Informatica clients and application services in a relational database to enable collaboration among the clients and services.
When you access a Model repository object from Live Data Map Administrator or the Data Integration Service, the client or service sends a request to the Model Repository Service. The Model Repository Service process fetches, inserts, and updates the metadata in the Model repository database tables.
Note: When you create the Model Repository Service, you do not associate it with other application services.
Catalog Service
The Catalog Service is an application service that runs Live Data Map in the Informatica domain. The Catalog Service manages the connections between service components and the users that have access to Enterprise Information Catalog and Live Data Map Administrator.
The catalog represents an indexed inventory of all the configured data assets in an enterprise. You can find metadata and statistical information, such as profile statistics, data asset ratings, data domains, and data relationships, in the catalog.
Informatica Cluster Service
The Informatica Cluster Service is an application service that runs and manages all the Hadoop services, Apache Ambari server, and Apache Ambari agents on an internal Hadoop cluster. If you choose the internal cluster deployment mode while you install Live Data Map, you need to create the Informatica Cluster Service before you create the Catalog Service. You can then specify the Informatica Cluster Service value when you create the Catalog Service.
Content Management Service Overview
The Content Management Service is an application service that manages reference data. It provides reference data information to the Data Integration Service and to the Developer and Analyst tools. A master Content Management Service maintains probabilistic model and classifier model data files across the domain.
The Content Management Service manages the following types of reference data:
- Address reference data
- You use address reference data when you want to validate the postal accuracy of an address or fix errors in an address. Use the Address Validator transformation to perform address validation.
- Identity populations
- You use identity population data when you want to perform duplicate analysis on identity data. An identity is a set of values within a record that collectively identify a person or business. Use a Match transformation or Comparison transformation to perform identity duplicate analysis.
- Probabilistic models and classifier models
- You use probabilistic or classifier model data when you want to identify the type of information that a string contains. Use a probabilistic model in a Parser or Labeler transformation. Use a classifier model in a Classifier transformation. Probabilistic models and classifier models use probabilistic logic to identify or infer the type of information in the string. Use a Classifier transformation when each input string contains a significant amount of data.
- Reference tables
- You use reference tables to verify the accuracy or structure of input data values in data quality transformations.
The Content Management Service also compiles rule specifications into mapplets.
Use the Administrator tool to administer the Content Management Service. Recycle the Content Management Service to start it.
