Controlling parallel back-end session startup

This setting controls the maximum number of back-end sessions that are started in parallel for a given database. Sometimes, there is a burst of requests for one database (such as starting up a Rational® Synergy client) but the load slows down after a while. Starting many back-end sessions at the same time slows down the startup. Also, many of those back-end sessions might not be necessary after the short burst periods. Instead, the serve only starts back-end sessions in parallel up to the number that is set by this key.

Procedure

To change the server configuration:

  1. Stop the server.
  2. To change this value for all databases, modify the cm.webserver.parallel.startups value in the ccm.server.properties file.
  3. To set a different value for a specific database, create a key called cm.webserver.parallel.startups.database name in the ccm.server.properties file, and then assign the new value.
  4. Restart the server so that the changed values take effect.

Example

Examples for setting database-specific values are located in Controlling the maximum back-end sessions.
