Administering Connections V5.5Welcome to the IBM Connections V5.5 documentation. IBM Connections is social networking software designed for the workplace. Its features help you to establish dynamic networks that connect you to the people and information you need to achieve your business goals.
AdministeringRun administration and maintenance tasks to keep your environment up-to-date. For example, learn how to customize your deployment or how to use the wsadmin utility to edit configuration files. You can also schedule tasks, maintain application databases, moderate content, or manage users and their roles.
Disabling widgetsYou can disable widgets from displaying on the Home page or elsewhere in IBM® Connections when you no longer want them to be available to your users.
Editing widgetsEdit a widget to change its name, description, or deployment descriptor.
Removing widgetsIf a third-party widget is no longer used or needed, you can remove it from the widget catalog. You cannot remove IBM® Connections widgets from the catalog, you can only disable them.
Administering SearchThe Search service provides a point for performing full text and tag searches across all the deployed IBM® Connections applications. Search is a required application for all IBM® Connections applications, and it must be running to prevent unexpected behaviors in the other applications.
Managing the Search indexThe Search application uses a Lucene 3.0.3 index, supplemented by social facet information. The location of the Search index is mapped to an IBM® WebSphere® Application Server variable, SEARCH_INDEX_DIR. The value of this variable is set to CONNECTIONS_DATA_DIRECTORY/search/index by default.

Managing the Search index

The Search application uses a Lucene 3.0.3 index, supplemented by social facet information. The location of the Search index is mapped to an IBM® WebSphere® Application Server variable, SEARCH_INDEX_DIR. The value of this variable is set to CONNECTIONS_DATA_DIRECTORY/search/index by default.

The index is generated by retrieving all the necessary information from each IBM Connections application on an administrator-defined schedule. Each task defines which applications to crawl and whether to optimize the index at the end of the task. The following applications can be indexed: Activities, Blogs, Bookmarks, Communities, Files, ECM files, Forums, Profiles, and Wikis. Status updates and community calendar events can also be indexed.

Search uses the WebSphere Application Server scheduling service for creating and updating the Search index. The scheduling service is based on the Cron calendar, which uses predefined date algorithms to determine when a task should run. While the scheduling service supports the use of a Simple calendar, this is not currently supported for IBM Connections. For more information about the WebSphere Application Server scheduler, see Scheduling tasks.

IBM Connections applications maintain delete and access-control update information for a maximum of 30 days. If indexing is not performed on an index for 30 days, that index is considered to be out-of-date and reindexing is necessary. You must delete and recreate the index to ensure data integrity.

Note: When indexing on a Microsoft® Windows® 2008 deployment, you might get the following error: java.io.IOException: Access is denied. This error is caused by an underlying Lucene issue and prevents the index from being updated. To resolve the problem, restart all the machines in the cluster.
