To enable plug-in logs, set LogLevel to debug. The logs will be included in the file pointed to by ErrorLog. It contains the following sections: Section 3. Open the httpd. Edit the file to add the following code Sample httpd. WLS parameter Example Sample httpd. In this example, the MatchExpression parameter syntax for expressing the filename pattern, the WebLogic Server host to which HTTP requests should be forwarded, and various other parameters is as follows:.
You must define a unique value for 'ServerName'or some Plug-In parameters will not work as expected. This section contains a sample httpd. You can use this sample as a template and modify it to suit your environment and server. Set clientCertProxy to True in the web. This parameter can be used with a third party proxy server such as a load balancer or an SSL accelerator to enable 2-way SSL authentication.
If you use weblogic. Change the alias name to obtain a different trusted CA file from the keystore. The following are known issues that may arise when you configure the Apache plug-in to use SSL. When the Apache HTTP Server Plug-In attempts to connect to WebLogic Server, the plug-in uses several configuration parameters to determine how long to wait for connections to the WebLogic Server host and, after a connection is established, how long the plug-in waits for a response.
If the plug-in cannot connect or does not receive a response, the plug-in attempts to connect and send the request to other WebLogic Server instances in the cluster. If the connection fails or there is no response from any WebLogic Server in the cluster, an error message is sent. Figure demonstrates how the plug-in handles failover. Failure of the WebLogic Server host to respond to a connection request could indicate the following problems:. Failure of all WebLogic Server instances to respond could indicate the following problems:.
The numeric value is the number of seconds to wait and may be set to any value between 30 and If you are running only a single WebLogic Server instance the plug-in only attempts to connect to the server defined with the WebLogicHost parameter. If the attempt fails, an HTTP error message is returned.
When you use the WebLogicCluster parameter in your httpd. After the first request is routed to one of these servers, a dynamic server list is returned containing an updated list of servers in the cluster. The updated list adds any new servers in the cluster and deletes any that are no longer part of the cluster or that have failed to respond to requests.

Open the httpd. Edit the file to add the following code Sample httpd. WLS parameter References can be identified with the prefix weblogic: to easily identify them, for example: Apache 2.
If the configuration uses these directives, the following note will appear during startup: [Thu May 14 ] [warn] weblogic: The Debug directive is ignored. The web server log level is used instead. If the connection fails or there is no response from any WebLogic Server in the cluster, an error message is sent.
Figure demonstrates how the plug-in handles failover. Failure of the WebLogic Server host to respond to a connection request could indicate the following problems:. Failure of all WebLogic Server instances to respond could indicate the following problems:.
The numeric value is the number of seconds to wait and may be set to any value between 30 and If you are running only a single WebLogic Server instance the plug-in only attempts to connect to the server defined with the WebLogicHost parameter.
If the attempt fails, an HTTP error message is returned. When you use the WebLogicCluster parameter in your httpd. After the first request is routed to one of these servers, a dynamic server list is returned containing an updated list of servers in the cluster. The updated list adds any new servers in the cluster and deletes any that are no longer part of the cluster or that have failed to respond to requests.
This list is updated automatically with the HTTP response when a change in the cluster occurs. When a request contains session information stored in a cookie or in the POST data, or encoded in a URL, the session ID contains a reference to the specific server instance in which the session was originally established called the primary server and a reference to an additional server where the original session is replicated called the secondary server.
A request containing a cookie attempts to connect to the primary server. If that attempt fails, the request is routed to the secondary server. If both the primary and secondary servers fail, the session is lost and the plug-in attempts to make a fresh connection to another server in the dynamic cluster list. See Figure Connection Failover.
