Administer portlet preferences for Portlet load monitoring

We can set portlet preferences to influence in which cases Portlet load monitoring blocks or reenables JSR portlets.

  • Maximum number of concurrent requests
  • Reactivation limit of concurrent requests for reactivating the portlet
  • Allowed average response time. We can configure the sample number of requests by which this average response time for portlets is calculated.

  1. Log in to the portal using a portal administrator user ID and go to...

      Administration | Portlet Management | Portlets

    The Manage Portlets portlet is displayed. It lists the portlets in the portal.

  2. Search for the portlet for which we want to set portlet preferences.

  3. Select the Configure Portlet icon.

  4. Add a new portlet preference as required and type number for the new portlet preference as required:

    • To set the maximum number of requests to allow for this portlet, for the new portlet preference, add...

        com.ibm.wps.pe.plm.maxrequest = xyz
      For example, to allow this portlet no more than 15 concurring requests, specify...

        com.ibm.wps.pe.plm.maxrequest = 15

    • To set the reactivation limit for this portlet, for the new portlet preference, add...

        add com.ibm.wps.pe.plm.minrequest = xyz
      For example, to have this portlet to be reenabled when its concurrent requests fall back to 5 or less, specify...

        com.ibm.wps.pe.plm.minrequest = 5

    • To set the allowed average response time for this portlet, add...

        com.ibm.wps.pe.plm.average.time.processing = xyz

      ...where xyz is the average response time in milliseconds. For example, if specified...

        com.ibm.wps.pe.plm.average.time.processing = 3000

      ...and the average response time for this portlet exceeds 3 seconds, then Portlet load monitoring blocks further requests to this portlet.

  5. Click the Add button to add the preference.

  6. Save the changes by clicking the OK button.


What to do next

As an alternative, we can define a portlet preference before deploying the portlet. In this case add the portlet preference to the portlet.xml deployment descriptor of the WAR file.
