Trace Analyzer
Trace Analyzer is a simple tool designed to display SQL trace in a Graphical format and hence provide a richer more interactive way of display the data. It allows users to dynamically rank their SQL and drill down to the individual statements. It also lists the bind parameters and explain plans of SQL statement
CPU Monitor
CPU Monitor is a lightweight Java app that uses Secure Shell (ssh) to scrape information from a server and chart its configuration and current load. It communicates directly with the server and as a result doesn’t require an agent to be running on the target. It currently supports Linux, Solaris and Mac OS servers with more OS’s coming shortly
Database Time Monitor
Database Time Monitor is a simple standalone tool that enables you to see how “Database Time” is being used by your Oracle application. It’s designed to be as simple as possible without any dependencies. It will run against Oracle Enterprise and Standard Edition. The tool works against Oracle 11g but at present 10g support is still being worked and should be in the next release.
