Configuring PEP cache settings for data protection rules in Data Virtualization
To improve performance, you can cache IBM Knowledge Catalog data protection rules in the Data Virtualization policy enforcement point (PEP) cache.

Before you begin

Required role: To complete this task, you must have the Data Virtualization Manager role. For more information, see Data Virtualization roles.

About this task

You can configure the PEP cache settings by using the Service settings UI. By default, the PEP cache is configured with a live time of 10 seconds and a size of 2000 entries. You can use the short default live time for proofs of concept to minimize the potential delay of updates. In production environments, increase the live time to improve performance.

Procedure

To configure the PEP cache settings, complete the following steps:

  1. On the navigation menu, click Data > Data virtualization to reveal the service menu.
    The service menu opens to the Data sources page by default.
  2. On the service menu, click Settings > Service settings.
    The General page appears.
  3. On the Governance tab, change the following settings as appropriate:
    • Cache size is the maximum number of cached responses from the IBM Knowledge Catalog policy service.
    • Cache live time determines how long a cached response remains valid in the cache, in seconds.
  4. Save your changes.
