Creating a Catalog Service

Creating a Catalog Service

Create a Catalog Service to run the Enterprise Data Catalog application and manage the connections between the Enterprise Data Catalog components. You can configure the general, application service, and security properties of the Catalog Service.
If you plan to deploy Enterprise Data Catalog on multiple nodes, ensure that you configure Informatica Cluster Service and Catalog Service on separate nodes.
The Catalog Service has the same privileges as the user account that creates it. Ensure that the user account does not have privileges to read or modify sensitive files on the system.
  1. In the Administrator tool, select a domain, and click the
    Services and Nodes
    tab.
  2. On the Actions menu, click
    New
    Catalog Service
    .
    The
    New Catalog Service Step 1 of 4
    dialog box appears.
  3. Configure the general properties in the dialog box.
    The following table describes the properties:
    Property
    Description
    Name
    Name of the service. The name is not case-sensitive and must be unique within the domain. The name cannot exceed 128 characters or begin with @. The name cannot contain character spaces. The characters in the name must be compatible with the code page of the Model repository that you associate with the Catalog Service.
    The name cannot contain the following special characters:
    ` ~ % ^ * + = { } \ ; : ' " / ? . , < > | ! ( ) ] [
    Description
    Description of the service. The description cannot exceed 765 characters.
    Location
    Domain in which the service runs.
    License
    License to assign to the Catalog Service. Select the license that you installed with Informatica.
    Node
    Node in the Informatica domain on which the Catalog Service runs. If you change the node, you must recycle the Catalog Service.
    Backup Nodes
    If your license includes high availability, nodes on which the service can run if the primary node is unavailable.
  4. Click
    Next
    .
    The
    New Catalog Service - Step 2 of 4
    dialog box appears.
  5. Configure the application service properties in the dialog box.
    The following table describes the properties:
    Property
    Description
    Model Repository Service
    Model Repository Service to associate with the Catalog Service. The Model Repository Service manages the Model repository that Enterprise Data Catalog uses. If you update the property to specify a different Model Repository Service, recycle the Catalog Service.
    User name
    The database user name for the Model repository.
    Password
    An encrypted version of the database password for the Model repository.
    Security Domain
    Name of the security domain that includes the
    User name
    .
  6. Click
    Next
    .
    The
    New Catalog Service - Step 3 of 4
    dialog box appears.
  7. Configure the security properties in the dialog box.
    The following table describes the properties:
    Property
    Description
    HTTP Port
    A unique HTTP port number used for each Data Integration Service process. The defaults is 8085.
    Enable Transport Layer Security
    Indicates that the Catalog Service must use HTTPS. If you did not configure the Data Integration Service to use HTTPS, the Catalog Service does not start.
    HTTPS Port
    Port number for the HTTPS connection.
    Keystore File
    Path and file name of the keystore file. The keystore file contains the keys and certificates required if you use the SSL security protocol with Catalog Administrator. Required if you select Enable Transport layer Security.
    When Enterprise Data Catalog creates the Catalog Service, Enterprise Data Catalog exports the keystore to a certificate and stores the certificate in the keystore directory. Ensure that you configure the read and write permissions on the directory for Enterprise Data Catalog to successfully store the certificate.
    Keystore Password
    Password for the keystore file. Required if you select Enable Transport layer Security.
    SSL Protocol
    Secure Sockets Layer protocol to use.
  8. Click
    Next
    .
    The
    New Catalog Service - Step 4 of 4
    dialog box appears.

    The following table describes the properties:
    Property
    Description
    Cluster Type
    Select one of the following options to indicate the deployment type for Enterprise Data Catalog:
    • External Cluster. Deploy Enterprise Data Catalog in an external Hadoop cluster on Hortonworks, ClouderaManager, or Azure HDInsight.
    • Internal Cluster. Deploy Enterprise Data Catalog in the embedded Hadoop cluster on Hortonworks.
    Hadoop Distribution
    Applicable if you select the
    External Cluster
    option for
    Cluster Type
    . Select one of the following options to specify the Hadoop distribution:
    • ClouderaManager. Use this option if you want to use a ClouderaManager Hadoop distribution.
    • Hortonworks. Use this option if you want to use a Hortonworks Hadoop distribution.
      If you select ClouderaManager or Hortonworks as the Hadoop distribution, Enterprise Data Catalog automatically identifies the following properties for the Hadoop-distribution type:
      • ZooKeeper Cluster URI
      • HDFS Namenode URI
      • Yarn resource manager URI
      • Yarn resource manager HTTPS or HTTP URI
      • History Server HTTP URI
      • HDFS Service Name for High Availability
      • Yarn resource manager scheduler URI
    • HDInsight. Use this option if you want to use an Azure HDInsight Hadoop distribution.
    • Others. Use this option if you want to manually specify all the properties for a ClouderaManager, Hortonworks, or an Azure HDInsight Hadoop distribution. Make sure that you configure the following custom options for the Catalog Service:
      • LdmCustomOptions.yarn-site.yarn.application.classpath
      • LdmCustomOptions.yarn-site.yarn.nodemanager.webapp.address
      • LdmCustomOptions.yarn-site.yarn.nodemanager.webapp.https.address
