Two changes in the custom Java class loader used for UDRs.

First, the class loader now adds any jar files stored in

$TRAF_HOME/udr/public/external_libs to its CLASSPATH.

The choice of this directory is anticipating work on

isolated UDFs, see TRAFODION-2561.

Second, the custom class loader LmClassLoader now uses to do most of the work. This allows

us to delete a lot of code in this file. When this class

was first written, many years ago, the URLClassLoader was

probably not yet available.

Finally, with the new class loader, the JDBC predefined

UDF can also be simplified.

[TRAFODION-2420] RMS enhancements Introduced 2 new counters HeapWM: - "SQL Heap WM" - Tracks the high water mark of the used memory including space buffer and bmo operator memory. It is enough to monitor this counter alone to track the memory utilization of the query.

scrIOTime: "Scr. IO Time" - Tracks the IO time taken to read/write to

the scratch files at BMO operator level

Introduced a 'Single line Format' option to display BMO stats and SE stats

in a single line format to enable exporting the output to Excel easily.


Removed and cleaned up the code further

Also fixed memory corruption issues seen with GET STATISTICS command.
