Set up the Missed Absolute Path Cache

To improve the performance of contextual linking you can enable a Missed Absolute Path Cache. The Missed Absolute Path Cache functionality requires a dynamic object cache to be setup in WAS before it can be utilized. This cache should be installed by default, but if you need to create this, follow these instructions:

1. In a non-clustered environment:

   1. Login to the WebSphere Administrative console for your server.

   2. Go to Resources tree > Cache Instances .

   3. Click Object cache instances.

   4. In the scope section, select the node on which your server is located and then select the server on which the cache is to be set up.

   5. Click Apply to save your choices.

   6. Click New to create a new cache.

   7. Enter missed in the Name field and services/cache/iwk/missed in the JNDI name field. These values are used to lookup the cache and use it. Leave all other fields set to their default values.

   8. Click OK at the bottom of the form and then Save.

   9. To enable the cache for your Web content, edit WCMConfigService.properties and ensure missed_absPath.cache.enable=true .The WCMConfigService.properties file is located in the PROFILE_HOME/PortalServer/wcm/shared/app/config/wcmservices/ directory.

      Restart WebSphere Portal to enable any configuration changes made to this file.

2. In a clustered environment:

   1. Login to the WebSphere Administrative console for your server.

   2. Go to Resources > Cache Instances > Object cache instances .

   3. Select a scope from the Scope selection drop-down list or uncheck the Show scope selection drop-down check box, click the Browse Clusters button, and then choose the cluster that you want to create the cache for.

   4. Click Apply to save your choices.

   5. Click New to create a new cache.

   6. Enter missed in the Name field and services/cache/iwk/missed in the JNDI name field. These values are used to lookup the cache and use it. Leave all other fields set to their default values.

   7. Select Enable Cache Replication.

   8. Go to the Full group replication domain drop-down box and select the name of the cluster you want to cache.

   9. Select Choose Push-Only from the Replication type drop down box.

   10. Enter 1 in the Push Frequency field. Leave all other fields set to their default values.

   11. Click OK and then Save > Save > OK.

   12. To enable the cache for your Web content, edit WCMConfigService.properties on every server in the cluster and ensure missed_absPath.cache.enable=true .The WCMConfigService.properties file is located in the PROFILE_HOME/PortalServer/wcm/shared/app/config/wcmservices/ directory.

       Restart WebSphere Portal to enable any configuration changes made to this file.
