If you installed online product documentation with your previous version of DB2 for Windows, OS/2, AIX, HP-UX or Solaris, or if you installed another IBM product like VisualAge C++ or VisualAge for Java, an online search system called NetQuestion was also installed automatically.
If the version of NetQuestion that comes with DB2 Version 7 is later than the version of NetQuestion currently present on your system, the current version will be upgraded and any existing document indices will be re-registered with NetQuestion. This will be done automatically for you during DB2 installation.
For more information on NetQuestion, refer to the Installation and Configuration Supplement.
