Configuring search functions for clusters
You can enable the search functions for use in clusters by changing a setting in the System Properties application.
About this task
Several search functions depend on Lucene indexing of the search objects. The Lucene index files must be placed in a shared disk location that is accessible by all nodes in the cluster. These index files are used by the Global Search and Self Service Global Search applications, as well as search functions in other service desk applications.
Procedure
- Set up the cron task PmObjSearchCron to create the Lucene index files. For more details, see the Configuring the search and auto-classification functions section. When running the product in a clustered environment, only one of the cluster nodes must be running the PmObjSearchCron cron task to create and update the search indexes. This task should be run on a different JVM from the product user interface.
- Create a network path share that can be accessed by all servers. For example, //cronserver/indexing_path.
- In the System Properties application, set the LUCENEOBJINDEX property to the network path share that you specified. The default location of the property is <websphere_install>/profiles/Custom01/objectsearchindex.
