    Tool for monitoring of OCI client applications [f.e.: TOAD/TOra, or any OCI-based fat client] interaction with Oracle Database. Monitors SQL statements and values passed/fetched between client application and RDBMS. Consists of simple and nice GUI [C#] and events handler [C++] with quite a lot of OCI hacking. Interface between handlers and tool's GUI is through tailing of XML "pipeline" files in $HOME/.ocimonitor directory. Tool is quite similar to Quest SQLMonitor, which is unable to trace values.
