2.4 编译
ant
此时会编译出一个版本 benchmarksql-5.0/dist/BenchmarkSQL-5.0.jar，但是该版本并不支持MySQL的TPC-C测试，需要做如下的修改。
3 修改benchmarksql源码
3.1 修改benchmarksql-5.0/src/client/jTPCC.java，增加mysql相关部分，如下所示：
if (iDB.equals("firebird"))
dbType = DB_FIREBIRD; else if (iDB.equals("oracle"))
dbType = DB_ORACLE; else if (iDB.equals("postgres"))
dbType = DB_POSTGRES; else if (iDB.equals("mysql"))
dbType = DB_UNKNOWN; else
{ log.error("unknown database type '" + iDB + "'"); return;
}3.2 修改benchmarksql-5.0/src/client/jTPCCConnection.java， SQL子查询增加"AS L"别名，如下所示：
default:
stmtStockLevelSelectLow = dbConn.prepareStatement( "SELECT count(*) AS low_stock FROM (" + " SELECT s_w_id, s_i_id, s_quantity " + " FROM bmsql_stock " + " WHERE s_w_id = ? AND s_quantity < ? AND s_i_id IN (" + " SELECT ol_i_id " + " FROM bmsql_district " + " JOIN bmsql_order_line ON ol_w_id = d_w_id " + " AND ol_d_id = d_id " + " AND ol_o_id >= d_next_o_id - 20 " + " AND ol_o_id < d_next_o_id " + " WHERE d_w_id = ? AND d_id = ? " + " ) " + " )AS L"); break;3.3 编译修改后的源码，此时得到的benchmarksql版本 benchmarksql-5.0/dist/BenchmarkSQL-5.0.jar 已经支持MySQL的TPC-C测试。
cd benchmarksql-5.0
ant
4 修改相关脚本，支持MySQL
4.1. 在benchmarksql-5.0/run目录下，创建文件prop.mysql，内容如下：
db=mysql driver=com.mysql.jdbc.Driver conn=jdbc:mysql://127.0.0.1:3306/benchmarksqluser=benchmarksql password=123456warehouses=1loadWorkers=4terminals=1//To run specified transactions per terminal- runMins must equal zerorunTxnsPerTerminal=10//To run for specified minutes- runTxnsPerTerminal must equal zerorunMins=0//Number of total transactions per minutelimitTxnsPerMin=300//Set to true to run in 4.x compatible mode. Set to false to use the//entire configured database evenly.terminalWarehouseFixed=true//The following five values must add up to 100//The default percentages of 45, 43, 4, 4 & 4 match the TPC-C specnewOrderWeight=45paymentWeight=43orderStatusWeight=4deliveryWeight=4stockLevelWeight=4// Directory name to create for collecting detailed result data.// Comment this out to suppress.resultDirectory=my_result_%tY-%tm-%td_%tH%tM%tS osCollectorScript=./misc/os_collector_linux.py osCollectorInterval=1//osCollectorSSHAddr=user@dbhostosCollectorDevices=net_eth0 blk_sda
4.2. 修改 文件：benchmarksql-5.0/run/funcs.sh，添加mysql 数据库类型。
function setCP()
{ case "$(getProp db)" in
firebird)
cp="../lib/firebird/*:../lib/*"
;;
oracle)
cp="../lib/oracle/*"
if [ ! -z "${ORACLE_HOME}" -a -d ${ORACLE_HOME}/lib ] ; then
cp="${cp}:${ORACLE_HOME}/lib/*"
fi
cp="${cp}:../lib/*"
;;
postgres)
cp="../lib/postgres/*:../lib/*"
;;
mysql)
cp="../lib/mysql/*:../lib/*"
;; esac
myCP=".:${cp}:../dist/*"
export myCP
}
...省略case "$(getProp db)" in
firebird|oracle|postgres|mysql)
;; "") echo "ERROR: missing db= config option in ${PROPS}" >&2 exit 1
;;
*) echo "ERROR: unsupported database type 'db=$(getProp db)' in ${PROPS}" >&2 exit 1
;;esac4.3 添加mysql java connector驱动，mysql-connector-java-5.1.45.jar 需自行下载。
mkdir -p benchmarksql-5.0/lib/mysql
cp mysql-connector-java-5.1.45.jar benchmarksql-5.0/lib/mysql/
4.4 修改benchmarksql-5.0/run/runDatabaseBuild.sh，去掉extraHistID
AFTER_LOAD="indexCreates foreignKeys extraHistID buildFinish"修改为： AFTER_LOAD="indexCreates foreignKeys buildFinish"
5 测试MySQL TPC-C
cd benchmarksql-5.0/run
./runDatabaseBuild.sh props.mysql
./runBenchmark.sh props.mysql
修改后的benchmarksql对MySQL进行TPC-C测试，结果如下所示：
02:58:47,071 [Thread-1] INFO jTPCC : Term-00,02:58:47,071 [Thread-1] INFO jTPCC : Term-00, Measured tpmC (NewOrders) = 136.7102:58:47,071 [Thread-1] INFO jTPCC : Term-00, Measured tpmTOTAL = 298.8102:58:47,071 [Thread-1] INFO jTPCC : Term-00, Session Start = 2018-12-27 02:53:4602:58:47,071 [Thread-1] INFO jTPCC : Term-00, Session End = 2018-12-27 02:58:4702:58:47,071 [Thread-1] INFO jTPCC : Term-00, Transaction Count = 1494
