Improving PMDB Updates

Policy Models send commands to their subscribers one by one in a loop. To control the maximum number of commands that the Policy Models send to each subscriber during each loop, use the updates_in_chunk token, which is described in the [pmd] section of the appendix “The pmd.ini File.”

If you increase the value of this token, the Policy Model uses fewer cycles to send commands. After each loop, the Policy Model checks for new requests. If the token is set higher, the Policy Model does not check for new requests as often.

For example, when you add a new subscriber to the Policy Model (using the sepmd -n option), increase the token value because other subscribers have already received the commands that the Policy Model is sending. The Policy Model spends less time sending commands to the other subscribers and spends more time sending commands to the new subscriber, shortening the time it takes to add the subscriber.

Note: Do not set this token value to more than 100.
