Policy Server Poll Interval Parameter

SOA Security Manager Agents contact the Policy Server regularly to receive any updated policies or encryption keys. The time interval for contacting the Policy Server can be adjusted by changing the PSPollInterval agent configuration parameter.

Increasing the time interval can reduce unnecessary traffic between the Agents and the Policy Server. Consider increasing the interval when your SOA Security Manager environment has any of the following characteristics:

• You have many Agents.
• Most of the SOA Security Manager policies are static, and do not change often.

  Note: For more information, see the Agent Configuration Guide or Agent Guide for your Agent.

Important! Increasing the PSPollInterval parameter also affects how quickly the Agents enforce SOA Security Manager policy changes. For example, suppose you change a Policy to revoke access for a terminated employee at 10:30, and your PSPollInterval parameter has a value of 3600 (the number of seconds in an hour). The Web Agents would not enforce the changed policy until as late as 11:30.
