Creating the Catalog Service

Create the Catalog Service to run the Live Data Map application and manage the connections between the Live Data Map components. You can configure the general, application service, and security properties of the Catalog Service.
Note: 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.
    Assign
    Node configuration type. Specify whether the node is in a single node, high availability, or grid environment.
    Node
    Node in the Informatica domain on which the Catalog Service runs. If you change the node, you must recycle the Catalog Service.
    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 Live Data Map 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.
    Data Integration Service
    Data Integration Service that you want to associate with the Catalog Service so that you can perform profiling and data domain discovery in Live Data Map. If you update the property to specify a different Data Integration Service, recycle the Catalog Service.
    Content Management Service
    Optional property. Application service that manages reference data. You specify this property if you want to include data domains in the Live Data Map results.
    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 Live Data Map Administrator. Required if you select Enable Transport layer Security.
    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 4of 4 dialog box appears.
    9. Configure the Hadoop cluster properties in the dialog box.
    The following table describes the properties:
    Property
    Description
    External Cluster
    Indicates the deployment type for Live Data Map. You can choose to deploy in an internal Hadoop cluster or an external Hadoop cluster on Cloudera.
    Zookeeper Addresses
    Applies to external cluster. Multiple Zookeeper addresses in a comma-separated list.
    HDFS Namenode URI
    Applies to external cluster. The URI to access HDFS.
    Use the following format to specify the NameNode URI in the Cloudera distribution:hdfs://<Namenode>:<Port>
    Where
    • - <Namenode> is the host name or IP address of the NameNode
    • - <Port> is the port number that the NameNode listens for Remote Procedure Calls (RPC).
    Yarn resource manager URI
    Applies to external cluster. The service within Hadoop that submits the MapReduce tasks to specific nodes in the cluster.
    Use the following format:<Hostname>:<Port>
    Where
    • - Hostname is the name or IP address of the Yarn resource manager.
    • - Port is the port number on which Yarn resource manager listens for Remote Procedure Calls (RPC).
    Yarn resource manager http URI
    Applies to external cluster. http URI value for the Yarn resource manager.
    Yarn resource manager scheduler URI
    Applies to external cluster. Scheduler URI value for the Yarn resource manager.
    Service Cluster Name
    Name of the service cluster. Ensure that you have a directory /Informatica/LDM/<ServiceClusterName> in HDFS.
    Note: If you do not specify a service cluster name, Live Data Map considers DomainName_CatalogServiceName as the default value. You must then have the /Informatica/LDM/<DomainName>_<CatalogServiceName> directory in HDFS. Otherwise, Catalog Service might fail.
    Is Cluster Secure
    Applies to external cluster. Choose to enable cluster authentication.
    Enable Service
    Select the option to enable the Catalog Service.
    Informatica Cluster Service
    Applies to internal cluster. Name of the Informatica Cluster Service, which is an application service that Live Data Map uses in internal cluster deployment.
    10. Click Finish.
If you did not choose to enable the Catalog Service earlier, you must recycle the service to start it.
