Create PXHCDR.sql

It performs two functions:

a set of pre-defined health-checks around parallel execution setup system-wide.
generates some html reports to diagnose PX issues. These diagnostics reports are based mainly on PX dynamic and static views.
This script installs nothing on the database, and updates nothing. Thus it is safe to use it on a production environment. It also works on read-only systems.

Script pxhcdr.sql only asks for two parameters: enter "D" if you have the Oracle Diagnostics Pack only. Enter "T" if you have the Oracle Tuning Pack license (which requires having the Diagnostic Pack license). Enter "N" if you have neither license. The second parameter is directory.
