Test the Read Capability of the Adapter

Test the Read Capability of the Adapter

When you test the read capability of the adapter, you test the connection definition, metadata of the data source, and operations that the adapter supports. After you specify the test settings and run the test, you can view the result of the read operation, read operation statistics, and the log file.
To debug the code, use the same debug configuration that you used to test the connection and metadata components of the adapter. You can also set breakpoints in the code that you want to debug.
After you define the debug configuration, you can launch the Test Read dialog box to test the read capabilities of the adapter.
  1. In the Connector Progress view, select the native metadata object that appears under Test Read.
    The Test Read dialog box appears with the default JVM environment settings and tracing level. The Informatica Connector Toolkit uses the JVM settings to run the debug configuration.
  2. If required, edit the JVM environment settings. Ensure that you use the same port number that appears in JVM settings for the connection properties in the debug configuration.
  3. Select the required tracing level. The default is normal. Based on the amount of detail that you require in the log file, you can override the default tracing level.
    You can set the following types of tracing level:
    None
    Does not override the default tracing level.
    Terse
    Logs initialization information and error messages and notification of rejected data.
    Normal
    Logs initialization and status information, errors encountered, and skipped rows due to transformation row errors. Summarizes mapping results, but not at the level of individual rows. This is the default tracing level.
    Verbose Initialization
    In addition to normal tracing, logs additional initialization details, names of index and data files used, and detailed statistics.
    Verbose Data
    In addition to verbose initialization tracing, logs each row. You can also get detailed statistics on where string data was truncated to fit the precision of a column.
  4. Click Next.
    The connection attributes that you defined for the adapter appears.
  5. Enter values for the connection attributes to test the connection to the data source.
  6. Click Connect.
    The Test Metadata page appears with the metadata imported from the data source.
  7. Select the native metadata objects and the corresponding native metadata fields to test the read operation.
  8. Click Next.
    Based on whether the selected native metadata object supports join and filter operations, the Join Condition page or Filter Condition page appears.
  9. If the native metadata object supports join operation, specify an expression in the Join Condition page.
    • To specify an Informatica platform expression for the join operation, perform the following steps:
      1. In the Definition section, select the native metadata object for which you want to specify the join condition.
      2. To change the join order, click Move Up or Move Down.
      3. Specify the join type in Join condition.
      4. To define a join condition, select values in the Left Field, Operator, and Right Field columns.
      5. To add additional join conditions, click Add.
      6. To remove a join condition, select the join condition and click Remove.
    • To specify a native expression for the join operation, enter the expression in the Definition section.
  10. If the native metadata object supports filter operation, select the Configure Filter option in the Filter Condition page and specify the filter condition.
    • To specify an Informatica platform expression for the filter operation, perform the following steps:
      1. In the Definition section, click Add to add an Informatica platform expression.
      2. In the Field column, select the field to use in the expression.
      3. In the Operation column, select a conditional operator to use in the expression.
      4. In the Value column, enter a value for the conditional expression.
    • To specify a native expression for the filter operation, enter the expression in the Definition section.
  11. After you specify expressions for the native metadata object, click Next.
    The Read Capability page appears.
  12. Specify values for the read capability attributes and then click Run.
    The Result page appears. You can view the result of the read operation, read operation statistics, and the log file in the Result page.
  13. Click Close.
