OraRep is a PL/SQL snippet (embedded in a shell script) which creates a well-formatted HTML report on a given database instance, providing you with an overview on your instance(s), some hints for performance tuning, and more. It has been tested with Oracle 8.1.7, 9.0.1, and 9.2. The script easily fits into a cron task to be run on a regular basis. Sample output (HTML) is included. OSPRep does the same job for Oracle StatsPack Reports based on SnapShot Levels up to 7, and provides additional "plugins" for more detailed reporting on special issues. It also optionally creates a separate page with charts to visualize the results and more.
Netinfo is a IP/MAC address locater for switched networks. It collects information from routers and L2/L3 switches and combines them to provide IP-MAC, IP-switch interface, and MAC-switch interface pairs. This makes it possible to determine the exact location of an IP or a MAC address in a network. It supports policy configuration and violation detection and can location duplicate IPs and IP address changes. It can also be used to monitor access to switch interfaces and stores a history of all collected information. Experimental support for automatic user lock-out in the event of violations is also included. It works with Cisco devices and is intended for use by NOCs and network administrators.
