Setting up the AREA hub

The BMC Remedy AR System plug-in server supports only one AREA plug-in directly. You can, however, add a single AREA Hub plug-in to the plug-in server and then add multiple AREA plug-ins to the AREA Hub plug-in. Plug-ins you add to the AREA Hub are referred to as Hub-plug-ins. The AREA Hub propagates the calls it receives from the Hub-plug-ins to the Plug-in server.

The AREA Hub loads the Hub-plug-ins in the order in which they appear in the ar.cfg or ar.conf file. That is, the first entry the AREA Hub finds in the ar.cfg file is the first plug-in loaded, the second entry the second, and so on.

Notes

  • You do not need to configure the AREA Hub manually to use multiple AREA LDAP plug-ins. See Configuring the AREA LDAP plug-in.
  • The AREA hub works only with DLLs. Java plug-in server has an inbuilt capability to chain across multiple Java AREA plug-ins. So, you do not need AREA hub for Java. You can configure multiple AREA Java plug-ins in pluginsvr_config.xml

To set up the AREA hub plug-in

  1. Create the following entry for the AREA hub in the ar.cfg file:

    Plugin: areahub.dll

    Note

    Make sure this is the only entry for an AREA plug-in in your ar.cfg file.

  2. Create an entry for the first AREA plug-in as follows:

    AREA-Hub-Plugin: my_area_plug-in.dll 
  3. If necessary, create entries for subsequent AREA plug-ins as follows:

    AREA-Hub-Plugin: my_area_plug-in_1.dll 
    AREA-Hub-Plugin: my_area_plug-in_2.dll 
    AREA-Hub-Plugin: my_area_plug-in_3.dll 
  4. Restart the AR System plug-in server.

    Note

    For information about restarting the plug-in server, see Restarting the plug-in server using the Set Server Info command.

    This doc states "Java plug-in server has an inbuilt capability to chain across multiple Java AREA plug-ins. So, you do not need AREA hub for Java. You can configure multiple AREA Java plug-ins in pluginsvr_config.xml".

     

    You need a link to a document on creating a Java AREA plugin that works for chaining as well as one for updating the pluginsvr_config.xml.

        Hi Prachi,

        Were you able to verify the question? To my understanding there is no need to configure additional plugins if you want chaining, since the area plugin already capable to do the chaining. But hub is in parallel and will authenticate against the first positive response, if any. So, I'm a bit confused by the notes section in the doc.

        Best regards, Jan

          Jan, See my answer to Fred above. You had a correct understanding. Here are the notes I think you are referring to: "You do not need to configure the AREA Hub manually to use multiple AREA LDAP plug-ins. See Configuring the AREA LDAP plug-in."

          "The AREA hub works only with DLLs. Java plug-in server has an inbuilt capability to chain across multiple Java AREA plug-ins. So, you do not need AREA hub for Java. You can configure multiple AREA Java plug-ins in pluginsvr_config.xml"

          The first of these means that if you are using the C plugin for AREA LDAP, the AREA LDAP Configuration form automatically configures AREA HUB do you do NOT need to configure it manually.

          The second note essentially means that ARA Hub is meant for the C plugin server and is not needed for the Java plugin server since it automatically chains.

      Fred, The Java Plugin server auto-chains in the order the plugins are defined (and therefore, loaded). The C plugin required AREA Hub. Since AREA Hub is a C plugin, it does not work with the Java Plugin server. For example, say you wanted to use RSSO and AREA LDAP. You would simply include both of those in the pluginsvr_config.xml and they will get called in the order that you put them. If most of your users are RSSO and only some are LDAP, you would probably put AREA LDAP second since you have the potential of locking users out if they provide a valid LDAP user name but the password was for RSSO instead. This way, anyone that logs in with RSSO does not have to first try LDAP. And Any LDAP users will quickly fail the RSSO login and then try LDAP. I hope this answers your questions.
