DB2 Text Search enables creating full-text search applications in IBM® DB2® for Linux®, UNIX®, and Windows® (LUW). For scenarios where high availability of the full-text search applications is required, a fail-over strategy must take into account that a DB2 Text Search setup involves two components: the DB2 database server and the text-search server. Text-search index catalog data and text-search index administration data are stored in the database and included in the DB2 High Availability Disaster Recovery (HADR) strategy. However, the text-search index collections are managed by the text-search server and are located on the file system. An extension of the database HADR strategy is, therefore, required to include the objects managed by the text-search server.
