BENCHMARKSQL README

USAGE:

benchmarksql的使用请查看文件：HOW-TO-RUN.txt

说明：

1. 针对ADBPG测试场景，本工程针对开源benchmarksql做了如下修改：
   • 修改了建表语句脚本，为某些表指定了分布键
   • 修复了在生成本地CSV数据文件时，CSV数据列和建表数据列不匹配的问题

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
