Upgrade Instructions

If you have VOS and ODS Release 4 or earlier, preserving your data while upgrading your installation and databases to the newest release requires the steps described below.

If you do not have any old data, you can skip this process, and simply use the new demo database, which has all the current ODS applications pre-installed.

VOS

1. Shut down the previous server.
2. Start the new server executable you have built or downloaded into the same directory.
3. There is a change in the DAV metadata represented in the RDF store. To bring all up-to-date, log in as dba with isql and execute:
   

   
   SQL> dav_replicate_all_to_rdf_quad (1);
   

   
   This is a one-time manual update which changes the DAV graph-name to have no trailing slash.

ODS

To upgrade the ODS applications and preserve any data you may have in them, do the following:

1. Shut down the server.
2. Take a backup of the database file(s), just in case.
3. Start the server.
4. Re-install/upgrade the VAD package corresponding to each installed applications. These are found in the share/virtuoso/vad/ directory in the tree where make install copies the results of the build. The upgrade can be done through the Conductor, or by executing the following command in isql:
   

   
   SQL> vad_install('ods_framework_dav.vad', 0);
   

   
   
5. Repeat for each installed package.
