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.
To enable caching for an object, stop the application that contains the logical data object, edit the object properties, and restart the application.
  1. In the Administrator tool, select the Data Integration Service.
  2. Click the
    Applications
    view.
  3. Select the application that contains the logical data object or virtual table for which you want to enable caching.
  4. Select the application that contains the logical data object 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. Expand the application, and select the logical data object.
  8. In the
    Logical Data Object Properties
    or
    Virtual Table Properties
    area, click
    Edit
    .
    The
    Edit Properties
    dialog box appears.
    The dialog box contains an Enable Caching checkbox, a Cache Refresh Period property, and a Cache Table Name property.
  9. In the
    Logical Data Object Properties
    area, click
    Edit
    .

    Edit Properties
    dialog box appears.
    The dialog box contains an Enable Caching checkbox, a Cache Refresh Period property, and a Cache Table Name property.
  10. Select
    Enable Caching
    .
  11. 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.
  12. 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.
