BENCHMARKSQL README =================== CHANGE LOG: ----------- Version 5.0 lussman & jannicash: -------------------------------------- + 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. 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. Version 4.1.0 2014-03-13 lussman: --------------------------------- + Upgrade to using JDK 7 + Upgrade to PostgreSQL JDBC 4.1 version 1101 driver + Stop claiming to support DB2 (only Postgres & Oracle are well tested) Version 4.0.9 2013-11-04 cadym: ------------------------------- + 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) Version 4.0.2 2013-06-06 lussman & cadym: -------------------------------------------- + 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 Version 3.0.9 2013-03-21 lussman: ---------------------------------- + Config log4j for rotating log files once per minute + Default flat file location to '/tmp/csv/' in table copies script + Drop incomplete & untested Windoze '.bat' scripts + Standardize logging with log4j + Improve Logging with meaningful DEBUG and INFO levels + 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: ----------------------------------- + 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 Versions 1.0 thru 2.2 2004 - 2012 lussman: ------------------------------------------- + Dare to Compare + Forked from the jTPCC project
