All the user administration functions are restricted to members of the dba group only. User manipulation functions do not generally return values. In case of error an error condition will be signalled. http://docs.openlinksw.com/virtuoso/VAD.html virtuoso.docs@openlinksw.com VAD - Virtuoso Application Distribution http://docs.openlinksw.com/virtuoso/VAD.html Thu, 28 Aug 2008 11:43:25 GMT VAD provides a package distribution framework for installation, management, dependency checking and un-installation of Virtuoso applications. A VAD package contains all required Virtuoso components, which would constitute an application or hosted solution, within a single distributable file. A VAD package cannot contain any system parts independent of Virtuoso thus excluding operating system executables, shared objects, installers or settings. Virtuoso and VAD provide the following abilities: http://docs.openlinksw.com/virtuoso/backup.html virtuoso.docs@openlinksw.com Data Backup & Recovery http://docs.openlinksw.com/virtuoso/backup.html Thu, 28 Aug 2008 11:43:25 GMT Administering a database involves taking backups and having a readiness to recover from backups and subsequent transaction logs. Backups can be taken in two principal ways: The Virtuoso backup functions can be used from any client directly, such as ISQL. It is possible, and perhaps preferable, to create stored procedures for performing the backup functions and scheduling these with the Virtuoso scheduler. http://docs.openlinksw.com/virtuoso/perfdiag.html virtuoso.docs@openlinksw.com Performance diagnostics http://docs.openlinksw.com/virtuoso/perfdiag.html Thu, 28 Aug 2008 11:43:25 GMT This section provides a checklist for improving performance of a Virtuoso server. If something does not work fast, this is mostly for the following reasons: Determining which is the case is simple. The result set returned by status ('') has most of the information. Do this twice with some 10 seconds between the samples and see the second result set. http://docs.openlinksw.com/virtuoso/ptune.html virtuoso.docs@openlinksw.com Performance Tuning http://docs.openlinksw.com/virtuoso/ptune.html Thu, 28 Aug 2008 11:43:25 GMT
