OraSnap

OraSnap provides Oracle snapshot-based^[37] performance monitoring and statistics gathering. It takes a very different approach to database administration and tuning from the tools we’ve looked at so far. OraSnap consists of a set of specialized SQL scripts that produce HTML output that can be used by a web browser. The product works somewhat like statspack , Oracle’s own new snapshot-based tool; statspack builds upon the older utlestat.sql performance tuning script, which provides report-based functionality.

Stewart McGlaughlin, the author of OraSnap, started work on this program back in 1998. The first version of OraSnap was released in December 1998, and, after various revisions and changes, the hallowed 1.0.0 version was quickly released to great acclaim. The latest OraSnap version (v2.2.1) was released in April 2000, and that version is compatible with Oracle Versions 7.3 through 8.1.5. The program will continue to be updated to keep the data dictionary views and other information up to date as Oracle9i reaches release. As of January 2001, the latest release of OraSnap, v2.3.3, is available with lots of new features.
