Major code overhaul. The per transaction type terminal data
generation, execution and terminal trace code is moved into a
module jTPCCTData. The database connection with all prepared
statements has moved into a module jTPCCConnection.
Add collecting per transaction result data and OS Level
resource usage collection. The R statistics package is used
to graph detailed information and a complete report in HTML
can be generated from the data.
Version 4.1.2 TBD jannicash:
Fixed one more preparedStatement() leak. Hopefully with the help
of Oracle's V$OPEN_CURSOR view we got them all now.
Fixed a possible deadlock problem in the NEW_ORDER transaction.
Multiple parallel transaction could attempt to lock the same
STOCK rows in reverse order. Sorting the order lines by item ID
avoids this problem.
Version 4.1.1 2016-01-31 jannicash:
Changed the status line to update only once per second. The previous
implementation was getting rather noisy at high throughput.
Fixed two preparedStatement() leaks that could cause ORA-01000 errors
on longer runs with high throughput.
Fixed a problem in the calculation of sleep time between
transactions when using limitTxnsPerMin that could cause the test
to hang at the end.
Added support for escaping ; as ; in SQL files to be able to load
functions and execute anonymous PL blocks (needed for next item).
Changed the definition of history.hist_id into a plain integer with
no special functionality. Two new database vendor specific SQL
scripts allow to enable the column after data load as an auto
incrementing primary key. See HOW-TO-RUN.txt for details.

Simplify "build.xml" to eliminate nbproject dependency
Defaults read in from propeerties
Groudwork laid to eliminate the GUI
Default GUI console to PostgreSQL and 10 Warehouses
Version 2.3.5 2013-01-29 lussman:
