OutOfMemory errors

If insufficient memory is allocated to the Java process, OutOfMemory may occur when you run graphs.

When a run fails due to inadequate memory allocation, the Console Tab includes messages such as the following: 
ERROR [DataIngestBatchConsumer-0] - Failed with the following exception: 
        java.lang.OutOfMemoryError: Java heap space
Exception in thread "DataIngestBatchConsumer-0" java.lang.OutOfMemoryError:
Java heap space

To avoid out OutOfMemory errors, increase the memory allocated to the Java process running the service. Use the Edit JRE dialog to modify the memory allocation to the Java process.

To modify memory allocations:

  1. In the menu bar, choose Window > Preferences

    Integrator ETL displays the Preferences dialog.

  2. In the left navigation pane of the Preferences dialog, expand the Java node. Click Installed JREs node.

    The Preferences dialog displays the Installed JREs page.

    Installed JREs page on the Preferences dialog
  3. In the Installed JREs menu, click on the checked JRE and then click Edit.

    Integrator ETL displays the Edit JRE page.

  4. In the Default VM Arguments field, specify a Java option to set the heap size, such as -Xmx1024M.

    The Edit JRE menu should look like this example:

    Edit JRE dialog
  5. Click Finish to apply your change and close the Edit JRE menu.
  6. Click OK to close the Preferences menu.
