Informatica PowerCenter Connector: Install and Configure

Follow these steps to perform the required configuration for the Informatica PowerCenter connector on the Informatica PowerCenter side and in Alation. This connector can be used to perform only Metadata Extraction and other features are not supported.

Preliminaries

Create a User

Create a user for the Informatica PowerCenter repository, refer to Creating a User.

Permissions

The following permission is required for the Informatica PowerCenter repository to access the metadata:

• Read access

JDBC URI

When building the URI, include the following components:

• Host

• Port

  • Oracle - 1521

  • DB2 - 50000

  • SQL Server - 1433

• Database name

URI Format for Oracle Data Source

oracle:thin:@<Host>:<Port>/<Database_Name>

Example:

oracle:thin:@11.132.126.242:1521/Data

URI Format for DB2 Data Source

db2://:<Host>:<Port>/<Database_Name>

Example:

db2://52.64.198.47:50000/data

URI Format for SQL Server Data Source

sqlserver://<Host>:<Port>;databaseName=<Database_Name>

Example:

sqlserver://10.22.146.138:1433;databaseName=data

Alation Setup and Authentication

STEP 1: Install the Connector

Important

Installation of an OCF connector requires Alation Connector Manager to be installed as a prerequisite.

1. If this has not been done on your instance, install Alation Connector Manager using the steps in: Install Alation Connector Manager.

2. Make sure that the OCF connector Zip file that you received from Alation is available on your local machine.

3. Install the connector on the Connectors Dashboard page: refer to Manage Connector Dashboard.

STEP 2: Create and Configure a New Informatica PowerCenter Data Source

1. Log in to the Alation instance and add a new Informatica PowerCenter source: Apps > Sources > Add > Data Source.

2. Provide the Title for data source and click on Continue Setup.

3. Select Database Type as follows based on the data source types from the dropdown menu:

   • Alation InfaOra OCF Connector

   • Alation Infa DB2 OCF Connector

   • Alation Infa SQLServer OCF Connector

You will be navigated to your new Informatica PowerCenter connectors Settings page.

General Settings

Perform the configuration on the General Settings tab:

1. Application Settings - Skip the Application Settings section because it is not relevant to this data source.

2. Specify Connector Settings:

   Parameter	Description
   Data Source Connection
   JDBC URI	Provide the JDBC URI : For Oracle data source, use URI Format for Oracle Data Source For DB2 data source, use URI Format for DB2 Data Source For SQL Server data source, use URI Format for SQL Server Data Source
   Username	Provide the Informatica PowerCenter repository username.
   Password	Provide the Informatica PowerCenter repository password.
   Logging Information
   Log Level	Select the Log Level to generate logs. The available log levels are based on the log4j framework.

4. Click Save.

5. Skip the Obfuscate Literals toggle because it is not relevant to this data source.

6. Under Test Connection, click Test to validate network connectivity.

Deleting the Data Source

You can delete your data source from the General Settings tab. Under Delete Data Source, click Delete to delete the data source connection.

Metadata Extraction

You can perform automated extraction or run a manual extraction for the data source.

Application Settings

• Enable Raw Metadata Dump or Replay: The options in this drop list can be used to dump the extracted metadata into files in order to debug extraction issues before ingesting the metadata into Alation. This feature can be used during testing in case there are issues with MDE. It breaks extraction into two steps: first, the extracted metadata is dumped into files and can be viewed; and second, it can be ingested from the files into Alation. It is recommended to keep this feature enabled only if debugging is required.

  • Enable Raw Metadata Dump: Select this option to save the extracted metadata into a folder for debugging purposes. The dumped data will be saved in four files (attribute.dump, function.dump, schema.dump, table.dump) in the folder opt/alation/site/tmp/ inside Alation shell.

  • Enable Ingestion Replay: Select this option to ingest the metadata from the dump files into Alation.

  • Off - Disable the Raw Metadata Dump or Replay feature. Extracted metadata will be ingested into Alation.
