Prepare an external directory folder

If you want to create a technical lineage for an external directory such as Informatica PowerCenter, SQL Server Integration Services (SSIS) or IBM InfoSphere DataStage, you must prepare a folder with the external directory's data source files.

If the external directory files do not have the necessary information, for example a database and a schema, to stitch the data sources, you can provide the connection definitions manually via a JSON configuration file. This file is optional, unless the useCollibraSystemName in the lineage harvester configuration file is set to true.

Tip 

Select an external directory:

Note You can also create and configure a JSON file to define a custom technical lineage.

Prerequisites

  • You have IBM InfoSphere Information Server version 11.5 or newer.
  • You have Informatica PowerCenter version 9.6 or newer.
  • You have SQL Server Integration Services 2012 or newer with package format version 6 or newer.
  • You have Microsoft Visual Studio version 2012 or newer.
  • You have downloaded the lineage harvester and you have the necessary system requirements to run it.
  • You have prepared the physical data layer in Data Catalog.
    Note To stitch the data objects in the source and target data sources in external directories with Data Catalog assets, you first have to register those data sources in Data Catalog.

Tip If you want to create a technical lineage for Informatica Intelligent Cloud Services Data Integration, you don't have to create a folder with data source files. You add your data source information directly to the lineage harvester configuration file.

Steps

Important If the useCollibraSystemName in the lineage harvester configuration file is set to true, you must provide an additional configuration file with connection definitions.
  1. Create a local folder.
  2. Export the Informatica objects or repository for which you want to create a technical lineage to the local folder.
    1. Open Informatica PowerCenter Workflow Manager.
    2. Connect to your Informatica repository.
    3. In the navigation panel, navigate to the workflow that contains the Informatica objects that you want to export.
    4. Right-click on the workflow and click Dependencies.
    5. In the Dependencies dialog box, do the following:
      1. Select Primary/Foreign Key dependencies.
      2. Select Global Shortcut dependencies.
      3. In the Object Types selector, select all object types except User-Defined.
    6. Click OK.
      The Dependencies dialog box closes.
      A dialog box with all Informatica objects appears.
    7. Select all objects.
    8. In the toolbar, click (Export to XML).
    9. Save the resulting XML files in your local folder.
    1. In the Informatica PowerCenter Client or PowerCenter Services bin directories, open pmrep.
    2. Export Informatica PowerCenter repository objects.
      Note Make sure that you export the same Informatica PowerCenter repository objects as during a manual export.
    3. Save the resulting XML files in your local folder.
    3. Note  All XML and parameter files, for example PAR, TXT or PRM files in this folder and its subfolders are taken into account when you create a technical lineage, but Collibra Data Lineage only shows a technical lineage for workflows that have mappings with sources, transformations and targets. Collibra supports the most common Informatica PowerCenter transformations. For more information, see the Informatica PowerCenter documentation.
  3. Put your parameter files in the right location.

    If...

    Then...

    all parameter files are PAR files

    No action required

    not all parameter files are PAR files

    1. Create a new folder in the local folder.
    2. Name the folder techlin-param.
    3. Move all parameter files that are used by the exported XML to the techlin-param folder.
    4. In the lineage harvester configuration file, set the recursive property to true.
    Note The lineage harvester only takes into account parameter files in the techlin-param folder.
  4. Optionally, create a source ID configuration file with connection definitions and system names:
    Tip If you previously created a technical lineage for Informatica PowerCenter with connection definitions, the connection_definitions.conf file will still be taken into account.
    1. Create a new JSON file in the lineage harvester config folder.
    2. Give the JSON file the same name as the value of the Id property in the lineage harvester configuration file.
      Example The value of the Id property in the lineage harvester configuration file is informatica-source-1. As a result, the name of your JSON file should be informatica-source-1.conf.
    3. For each data source, add the following content to the JSON file:

      Property

      		Description

      connectionDefinitions

      This section contains the connection properties to a source in Informatica PowerCenter.

				"collibraSystemName": "oracle-system-name2"
			}
		]
	}
}

    5. Important If you are using variables in Informatica PowerCenter, add the value of the variable instead of the name in the connection definitions JSON file. For exampple, if the parameter file contains $DBConnection_dwh=DWH_EXPORT then you add the following connection definitions to the JSON file: 
    {
	"DWH_EXPORT":

		{ "dbname": "DWH", "schema": "DBO" }
}
  5. Add a new section for Informatica PowerCenter to the lineage harvester configuration file.
  1. Create a local folder.
  2. Export the SSIS files for which you want to create a technical lineage.
    Tip You can export them directly from the SQL Server Integration Services repository or via Microsoft Visual Studio. For more information, see the SQL Server Integration Services documentation.
  3. Store the SSIS files to your local folder. Typically, the folder contains the following files:
    • SSIS package files (DTSX), containing the SQL Server Integration Services source code.
    • Connection manager files (CONMGR), containing environment and connection information.
    • Parameter files (PARAMS), if applicable.
    Note All files in this folder and subfolders are taken into account when you create a technical lineage. The lineage harvester automatically detects data sources in the SSIS files.
  4. Optionally, configure the connection definitions:
    Tip If the useCollibraSystemName in the lineage harvester configuration file is set to true, you must provide the connection_definitions.conf file.
    1. Create a new JSON file in the local folder.
    2. Name the JSON file connection_definitions.conf.
    3. For each supported data source, specify the relevant translations.

      Property

      		Description

      ConnStringRegExTranslation

      The parent element that opens the connection definitions.

      <regular expression>

      A regular expression that must match one or more connection strings.

      Note 

      Important considerations:

      • By default, the regular expression is not case sensitive. As a consequence, a regular expression can match with connection strings containing uppercase characters or lowercase characters.
      • The connection string is part of the SSIS connection manager.
      • SSIS connection managers are included in an SSIS package files (DTSX) or in connection manager files (CONMGR).
      Example 

      Regular expression: Server=sb-dhub;User ID=SYB_USER2;Initial Catalog=STAGEDB;Port=6306.*
      Explanation: The first section, up to .*, is a literal, but not case-sensitive, match of the characters. The dot (.) can match any single character. The asterisk (*) means zero or more of the previous, in this case any character.
      Match: Any connection string that starts with Server=sb-dhub;User ID=SYB_USER2;Initial Catalog=STAGEDB;Port=6306.
      Example: Server=sb-dhub;User ID=SYB_USER2;Initial Catalog=STAGEDB;Port=6306;Persist Security Info=True;Auto Translate=False;.

      dbname
      		The name of your database, to which the data source connection refers.
      schema

      The name of your schema, to which the regular expression refers.

      dialect

      The dialect of the referenced database.

      You can enter one of the following values:

      • azure, for an Azure SQL Server data source.
      • bigquery, for a Google BigQuery data source.
      • db2, for an IBM DB2 data source.
      • hana, for a SAP Hana data source.
      • hana-cviews, for SAP Hana data calculation views.
      • hive, for a HiveQL data source.
      • greenplum, for a Greenplum data source.
      • mssql, for a Microsoft SQL Server data source.
      • mysql, for a MySQL data source.
      • netezza, for a Netezza data source.
      • oracle, for an Oracle data source.
      • postgres, for a PostgreSQL data source.
      • redshift, for an Amazon Redshift data source.
      • snowflake, for a Snowflake data source.
      • spark, for a Spark SQL data source.
      • sybase, for a Sybase data source.
      • teradata, for a Teradata data source.
      collibraSystemName

      The name of the referenced data source's system or server.

      This property is only required when you set the useCollibraSystemName property in the lineage harvester configuration file to true. If this property is set to false, you can remove the collibraSystemName property or enter an empty string.

      Note You must use the same system name as the full name of the System asset that you create when you prepare the physical data layer in Data Catalog. If you don't prepare the physical data layer, Collibra Data Lineage cannot stitch the data objects in your technical lineage to the assets in Data Catalog.

      If the “useCollibraSystemName" property is:

      • false, system or server names in table references in analyzed SQL code are now ignored. This means that a table that exists in two different systems or servers is identified (either correctly or incorrectly) as a single data object, with a single asset full name.

      • true, system or server names in table references are considered to be represented by different System assets in Data Catalog. The value of the "collibraSystemName" field is used as the default system or server name.

      Copy code

      {
  "ConnStringRegExTranslation": {

    "Data Source=dhb-sql-prod;Initial Catalog=SFG_repl_staging;Provider=SQLNCLI11;Integrated Security=SSPI.*": {
      "dbname": "DATAHUB",
      "schema": "DBO",
      "dialect": "mssql",
      "collibraSystemName" : "WAREHOUSE"
    },

    "Server=sb-dhub;User ID=SYS_USER;Initial Catalog=STAGEDB;Port=6306.*": {
      "dbname": "STAGEDB",
      "schema": "STAGE_OWNER",
      "dialect": "sybase",
      "collibraSystemName" : ""
    }

  }
}

      Tip Click Copy code to copy the example to your clipboard.

  5. Add a section for SQL Server Integration Services to the lineage harvester configuration file.
  1. Create a local folder.
  2. Export the DataStage project files (DSX) for which you want to create a technical lineage.
    Tip You can either export a DataStage project manually or automatically via command line.
  3. Store the DataStage files in your local folder.
  4. Optionally, if your DataStage project uses environment variables, manually export the environment files (ENV).
  5. Give the environment files the same name as the DataStage project files. For example, if your project file is named datastage-project-1.dmx, you have you name your environment file datastage-project-1.env.
  6. Store the environment files in the same local folder.
    Important  
    • The lineage harvester only supports DSX and ENV files.
    • You can have one DSX file per DataStage project.
    • You can have one or none ENV file per DSX file.
    • The name of the DSX file and the ENV file has to be the same.
  7. Optionally, configure the connection definitions:
    1. Create a new JSON file in the local folder.
    2. Name the JSON file connection_definitions.conf.
    3. For each data source, specify the relevant translations:

      Property
