Step 2. Enable Data Object Caching for an Object

Step 2. Enable Data Object Caching for an Object

To enable caching for an object, stop the application that contains the logical data object or virtual table, edit the object properties, and restart the application.
  1. In the Administrator tool, click the Manage tab > Services and Nodes view.
  2. In the Domain Navigator, select the Data Integration Service.
  3. Click the
    Applications
     view.
  4. Select the application that contains the logical data object or virtual table for which you want to enable caching.
  5. Stop the application.
  6. Expand the application, and select the logical data object or virtual table.
  7. In the
    Logical Data Object Properties
     or
    Virtual Table Properties
     area, click
    Edit
    .
    The
    Edit Properties
     dialog box appears.
  8. Select
    Enable Caching
    .
  9. In the
    Cache Refresh Period
     property, enter the amount of time in minutes that the Data Object Cache Manager waits before refreshing the cache.
    For example, if you enter 720, the Data Object Cache Manager refreshes the cache every 12 hours. If you leave the default value of zero, the Data Object Cache Manager does not refresh the cache according to a schedule. You must manually refresh the cache using the infacmd dis RefreshDataObjectCache command.
  10. Leave the
    Cache Table Name
     property blank.
    When you enter a table name, the Data Object Cache Manager does not manage the cache for the object. Enter a table name only when you want to use a user-managed cache table. A user-managed cache table is a table in the data object cache database that you create, populate, and manually refresh when needed.
  11. Click
    OK
    .
  12. To generate indexes on the cache table based on a column, expand the logical data object or virtual table.
    1. Select a column, and then click
      Edit
       in the
      Logical Data Object Column Properties
       or
      Virtual Table Column Properties
       area.
      The
      Edit Column Properties
       dialog box appears.
    2. Select
      Create Index
       and then click
      OK
      .
  13. Restart the application.
    The Data Object Cache Manager creates and populates the cache table.
