CHANGE LOG:

Upgrade to PostgreSQL 9.3 JDBC 4.1 version 1102 driver
Improve support for Oracle
Re-implement the non-uniform random generator in TPC-C style.
Conform to clause 4.3.3.1 and enable lookup by last name
Add a switch to disable terminal-warehouse association, spreading the data access over all configured warehouses.
Re-worked the run shell scripts and the location of SQL files to make support of more database types easier.
Add support for Firebird (http://www.firebirdsql.org).
Add FOREIGN KEYS as defined by TPC-C 1.3.
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.

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.

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.

Incorporate new PostgreSQL JDBC 4 version 1100 driver
Changed default user from postgres to benchmarksql
Added id column as primary key to history table
Renamed schema to benchmarksql
Changed log4j format to be more readable
Created the "benchmark" schema to contain all tables
Incorporate new PostgreSQL JDBC4 version 1003 driver
Transaction rate pacing mechanism
Correct error with loading customer table from csv file
Status line report dynamically shown on terminal
Fix lookup by name in PaymentStatus and Delivery Transactions (in order to be more compatible with the TPC-C spec)
Rationalized the variable naming in the input parameter files (now that the GUI is gone, variable names still make sense)
Default log4j settings only writes to file (not terminal)

Removed Swing & AWT GUI so that this program is runnable from the command line
Remove log4j usage from runSQL & runLoader (only used now for the actual running of the Benchmark)
Fix truncation problem with customer.csv file
Comment out "BadCredit" business logic that was not working and throwing stack traces
Fix log4j messages to always show the terminal name
Remove bogus log4j messages

Default build is now with JDK 1.6 and JDBC 4 Postgres 9.2 driver
Remove outdated JDBC 3 drivers (for JDK 1.5). You can run as before by a JDBC4 driver from any supported vendor.
Remove ExecJDBC warning about trying to rollback when in autocommit mode
Remove the extraneous COMMIT statements from the DDL scripts since ExecJDBC runs in autocommit mode
Fix the version number displayed in the console
