Administer custom advisors for the proxy server

We can administer custom advisors for the proxy server. Custom advisors allow for more specific determination of target application server availability by sending protocol level requests to back-end servers. Custom advisors are unique based on the combination of the business level application ID and the composition unit ID.

Complete these steps to administer actions for the proxy server.

Tasks

1. From the administrative console, select Servers > Server Types > WebSphere proxy servers > proxy_server > Custom advisor policies.

2. Click the name of a custom advisor to change settings.

3. Specify the business level application ID.

4. Specify the composition unit ID.

5. Poll interval using seconds in the Poll interval field..

6. Specify the connection timeout using seconds in the Connect timeout field.

7. Specify the input/output timeout using seconds in the I/O timeout field.

8. Optional: Select Enable logging if we would like to use logging for this custom advisor. If we enable logging, then follow these steps:

   1. Optional: Select Enable log file wrapping if we would like wrapping turned on.

   2. Specify the maximum size of the log file using megabytes in the Log file size field.

9. Create mappings to be used by our custom advisor using one of the following sub-steps:
   1. Configure stand-alone application server mappings
   2. Configure application server cluster mappings
   3. Configure generic server cluster mappings

10. Optional: Click Delete to remove a selected mapping from the collection.

Subtopics

• Custom advisor policies
  Custom advisor policies help to determine target application server availability. Custom advisors are Java code modules that work within the proxy server to provide information about the application's availability to the proxy server selection code.
• Custom advisors collection
  Use this page to administer custom adviser policies. With custom advisors, we can determine the availability of a specific target application server by sending protocol level requests to back-end servers. Custom advisor policies are unique based on the combination of the business-level application ID and the composition unit ID.
• Custom advisor policy settings
  We can configure settings for a custom advisor policy. Custom advisor policies allow for more specific determination of target application server availability by sending protocol level requests to back-end servers. Custom advisor policies are unique based on the combination of the business-level application ID and the composition unit ID.
• Configure stand-alone application server mappings
  We can configure a stand-alone application server mapping. Stand-alone application server mappings specify that a stand-alone application server is mapped to a custom advisor.
• Configure application server cluster mappings
  We can configure an application server cluster mapping to specify which application server clusters a custom advisor will monitor.
• Configure generic server cluster mappings
  We can configure a generic server cluster mapping. A generic server cluster allows configuration of external servers into a logical cluster that can be used by the proxy server to route requests. Generic servers host a common set of resources and can receive routing actions as a unit. Generic server cluster mappings are configured to specify which generic server clusters a custom advisor will monitor.
