Removing cache entries through the Cache Monitor

The WebSphere Application Server Cache Monitor provides the options to manually invalidate cache entries.

Before beginning

Ensure that the cache monitor is enabled. To enable it, modify the server.xml configuration file in the runtime Liberty container. Add the element <feature>webCacheMonitor-1.0</feature> to the feature list in the file. When accessing the application, the port of the cache monitor is same as the port of the server endpoints. For the default Store container, this port is 8080/8443. For the Search container, it is 3737/3738.

Procedure

1. Launch the cache monitor using one of the following methods:

   1. We can access the Web application using a Web browser with the following Web address:

      http://host_name:port/cachemonitor

   2. However, for a more secure access, IBM recommends that you access the Administration host machine:

      https://admin_host_name:port/cachemonitor

   3. For example, if the virtual host VH_ instance_name_admin is used for installing the Cache Monitor, then the Cache Monitor can be accessed as:

      https://admin_host_name:8002/cachemonitor

2. Do one of the following steps:
