Add SQL Analysis Services Data to Informatica Enterprise Data Catalog

Use the CData JDBC Driver for SQL Analysis Services with the Informatica Enterprise Data Catalog to classify and organize data.

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData JDBC Driver for SQL Analysis Services, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's Enterprise Data Catalog. This tutorial shows how to classify and organize SQL Analysis Services data across any environment.

Load the JDBC Driver

To load the JDBC Driver:

  1. Install the JDBC Driver on the host running Informatica. For this article, it is assumed that the driver was installed into cdata.jdbc.ssas.SSAS Driver.
  2. $ java -jar setup.jar
  3. Navigate to the JDBC install directory and create a zip file called genericJDBC.zip containing the driver and its license file.
  4. $ cd ~/cdata-jdbc-driver-for-ssas/lib $ zip genericJDBC.zip cdata.jdbc.ssas.jar cdata.jdbc.ssas.lic
  5. Move the genericJDBC.zip file into the Catalog Service directory within Informatica. For this article, it is assumed that Informatica is installed into /opt/informatica. Working in this folder will probably require root permissions, so make sure to su or sudo to root before continuing.
  6. # mv genericJDBC.zip /opt/informatica/services/CatalogService/ScannerBinaries
  7. Edit the custom deployment configuration to unpack the zip file.
  8. # cd /opt/informatica/services/CatalogService/ScannerBinaries/CustomDeployer/ # nano scannerDeployer.xml

    After unpacking the existing ExecutionContextProperty nodes, add a new ExecutionContextProperty node with this content.

    <ExecutionContextProperty isLocationProperty="true" dependencyToUnpack="genericJDBC.zip"> <PropertyName>JDBCScanner_DriverLocation</PropertyName> <PropertyValue>scanner_miti/genericJDBC/Drivers</PropertyValue> </ExecutionContextProperty>
  9. Refresh the Catalog Service from the Admin console.

Configure the JDBC Resource

To configure the JDBC resource:

  1. Open the Catalog administrator and add a new JDBC resource with the following properties:
    • Driver Class: cdata.jdbc.ssas.SSASDriver
    • URL: jdbc.ssas:User=myuseraccount;Password=mypassword;URL=http://localhost/OLAP/msmdpump.dll;
    • 接続するには、Url プロパティを有効なSQL Server Analysis Services エンドポイントに設定して認証を提供します。XMLA アクセスを使用して、HTTP 経由でホストされているSQL Server Analysis Services インスタンスに接続できます。 Microsoft ドキュメント configure HTTP access tを参照してSQL Server Analysis Services に接続してください。

      SQL をSQL Server Analysis Services に実行するには、Analysis Services データの取得 を参照してください。接続ごとにメタデータを取得する代わりに、CacheLocation を設定できます。

      • HTTP 認証

        AuthScheme を"Basic" または"Digest" に設定してUser とPassword を設定します。CustomHeaders に他の認証値を指定します。

      • Windows (NTLM)

        Windows のUser とPassword を設定して、AuthScheme をNTLM に設定します。

      • Kerberos およびKerberos Delegation

        Kerberos を認証するには、AuthScheme をNEGOTIATE に設定します。Kerberos 委任を使うには、AuthScheme をKERBEROSDELEGATION に設定します。必要があれば、User、Password およびKerberosSPN を設定します。デフォルトでは、本製品 は指定されたUrl でSPN と通信しようと試みます。

      • SSL/TLS:

        デフォルトでは、本製品 はサーバーの証明書をシステムの信頼できる証明書ストアと照合してSSL/TLS のネゴシエーションを試みます。別の証明書を指定するには、利用可能なフォーマットについてSSLServerCert プロパティを参照してください。

      You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

      See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.

      Built-In Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the SQL Analysis Services JDBC Driver. Either double-click the .jar file or execute the .jar file from the command-line.

      java -jar cdata.jdbc.ssas.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

    Typical additional connection string properties follow:

    JDBC;MSTR_JDBC_JAR_FOLDER=PATH\TO\JAR\;DRIVER=cdata.jdbc.ssas.SSASDriver;URL={jdbc:ssas:User=myuseraccount;Password=mypassword;URL=http://localhost/OLAP/msmdpump.dll;};
  2. Username: user
  3. Password: password
  4. Note that the Username and Password properties are required, even if the driver you are using does not require them. In those cases, you can enter a placeholder value instead.

  5. Configure the metadata options to perform at least one source metadata scan. This scan uses the driver to determine what tables, views, and stored procedures are available through the service.
    • Source Metadata: Enable this option.
    • Catalog: Set this to the appropriate catalog for multi-catalog data sources. Otherwise, set this to CData.
    • Schema: Set this to the appropriate schema for multi-schema data sources. Otherwise, set this to the name of the service (for example, Couchbase).
    • Case-sensitivity: Generally this option should be disabled. Enable it only for data sources which are case-sensitive.
    • Import stored procedures: Enable this if you want to import stored procedure definitions in addition to tables and views.

    Other metadata scanners may be enabled as desired.

  6. Complete the driver configuration, optionally configuring custom attributes and a scanner schedule.
  7. Perform the metadata scan by navigating to the Monitoring tab and clicking Run. Depending upon the data source, this may takes a few minutes.

When the scan is complete, a summary of all of the metadata objects is displayed along with the status of the Metadata Load job. If any errors occur, you can open the Log Location link for the job to see the errors reported by Informatica or the driver.

Validate the Discovered Metadata

Open the Catalog Service browser to view the metadata extracted from the data source. Depending upon the options you selected when configuring the metadata scanner, you may see any combination of tables, views, and stored procedures for the resource you defined.
