Keep-Alive Connections in Weblogic Server (WLS) Web Server Plug-In (Doc ID 877744.1)

Last updated on MAY 30, 2024

Applies to:

Oracle WebLogic Server - Version 9.2 and later
Information in this document applies to any platform.


The documentation on the web server plug-in refers to a property called KeepAliveEnabled. It is turned on by default and it "improves performance by using a reusable pool of connections from the plug-in to WebLogic Server" (WLS). Based on this, the following questions might raise:

  • Is it possible to create a pool of connections to the WLS backend analogous to a JDBC Connection Pool, and then only reuse those connections instead of constantly creating new ones?
  • Is there a maximum number of connections that will be created, or is this restrained to the MaxClients directive of the particular Apache worker?
  • Is there a negative impact to increasing the value for the related parameter KeepAliveSecs?
