BenchmarkSQL 测试Oracle 12c TPC-C 性能-阿里云开发者社区

使用BenchmarkSQL测试一下Oracle 12c的TPC-C性能，同时对比一下PostgreSQL 9.5的性能。

测试机：

3 * PCI-E SSD，逻辑卷条带，XFS，数据块对齐，16核开HT，256G内存。

12c安装，配置请参考

下载benchmarksql

http://sourceforge.net/projects/benchmarksql/

下载安装 JDK7

http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk7-downloads-1880260.html
wget http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.rpm
rpm -ivh jdk-7u79-linux-x64.rpm

检查包安装位置(使用rpm安装时也可以直接指定位置)

rpm -ql jdk
...
/usr/java/jdk1.7.0_79/bin/java
...

配置JAVA环境变量，将ORACLE jdbc驱动拷贝到benchmark/run目录

$  cp ~/oracle/product/12.1.0/db_1/jdbc/lib/ojdbc6.jar   benchmarksql/run/
$  cp ~/oracle/product/12.1.0/db_1/jdbc/lib/ojdbc7.jar   benchmarksql/run/

$  export JAVA_HOME=/usr/java/jdk1.7.0_79
$  export PATH=$JAVA_HOME/bin:$PATH
$  export CLASSPATH=.:./ojdbc6.jar:./ojdbc7.jar:$CLASSPATH

修改runSQL.sh，加上$CLASSPATH，否则会报oracle驱动CLASS不存在的错误。

$  vi runSQL.sh
myCP="../lib/postgresql-9.3-1101.jdbc41.jar"
myCP="$myCP:../dist/BenchmarkSQL-4.1.jar"

myOPTS="-Dprop=$1"
myOPTS="$myOPTS -DcommandFile=$2"

java -cp .:$myCP:$CLASSPATH $myOPTS ExecJDBC

$ vi runLoader.sh 
java -cp .:$CLASSPATH:../lib/postgresql-9.3-1101.jdbc41.jar:../dist/BenchmarkSQL-4.1.jar -Dprop=$1 LoadData $2 $3 $4 $5

修改props.ora

$  vi props.ora 
driver=oracle.jdbc.driver.OracleDriver
conn=jdbc:oracle:thin:@localhost:1521:orcl12c
user=benchmarksql
password=benchmarksql

创建数据库用户

$  sqlplus "/ as sysdba"
SQL> create user benchmarksql identified by "benchmarksql";
SQL> grant dba,connect to benchmarksql;
SQL> alter user benchmarksql default tablespace users;

设置ORACLE 批量提交参数

SQL> alter system set commit_write='batch,nowait';

使用强制软解析

SQL> alter system set cursor_sharing=force;

使用O_DIRECT

SQL> alter system set filesystemio_options=directio scope=spfile;
SQL> alter system set disk_asynch_io=false scope=spfile;
(以上参数 lunar 建议后改为如下)
SQL> alter system set filesystemio_options=setall scope=spfile;
SQL> alter system reset disk_asynch_io scope=spfile;

修改最大连接数，打开游标数。

SQL> alter system set processes=1000 scope=spfile;
SQL> ALTER SYSTEM SET open_cursors=900 SCOPE=BOTH;

alter system set session_cached_cursors=0 scope=spfile;
(以上参数 lunar 建议后改为如下)
SQL> alter system reset session_cached_cursors scope=spfile;

重启数据库.

防止NUMA影响(需重启操作系统)：

grub.conf
numa=off

扩展表空间，防止空间不够。(1000个warehouse够用了）。

SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users01.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users02.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users03.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users04.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users05.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users06.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users07.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users08.dbf' size 31G;
SQL>  alter tablespace users add datafile '/disk1/digoal/oradata/users09.dbf' size 31G;
alter tablespace UNDOTBS1 add datafile '/disk1/digoal/oradata/undotbs1_01.dbf' size 31G;
alter tablespace UNDOTBS1 add datafile '/disk1/digoal/oradata/undotbs1_02.dbf' size 31G;
alter tablespace SYSTEM add datafile '/disk1/digoal/oradata/system_01.dbf' size 31G;
alter tablespace SYSAUX add datafile '/disk1/digoal/oradata/sysaux_01.dbf' size 31G;
alter tablespace TEMP add tempfile '/disk1/digoal/oradata/temp_01.dbf' size 31G;
alter tablespace TEMP add tempfile '/disk1/digoal/oradata/temp_02.dbf' size 31G;

新增redo log file，默认只有3个50MB的redo log，产生大量 log file switch (checkpoint incomplete)和 log file switch completion等待事件。

select group#,sequence#,bytes,members,status from v$log;

select member from v$logfile;

alter database add logfile group 4 ('/disk1/digoal/oradata/orcl12c/redo04.log') size 2g;
alter database add logfile group 5 ('/disk1/digoal/oradata/orcl12c/redo05.log') size 2g;
alter database add logfile group 6 ('/disk1/digoal/oradata/orcl12c/redo06.log') size 2g;
alter database add logfile group 7 ('/disk1/digoal/oradata/orcl12c/redo07.log') size 2g;
alter database add logfile group 8 ('/disk1/digoal/oradata/orcl12c/redo08.log') size 2g;
alter database add logfile group 9 ('/disk1/digoal/oradata/orcl12c/redo09.log') size 2g;
alter database add logfile group 10 ('/disk1/digoal/oradata/orcl12c/redo10.log') size 2g;

alter system switch logfile;
alter system switch logfile;
alter system switch logfile;
alter system switch logfile;
alter system checkpoint;

alter database drop logfile group 1;
alter database drop logfile group 2;
alter database drop logfile group 3;

rm -f /disk1/digoal/oradata/orcl12c/redo01.log
rm -f /disk1/digoal/oradata/orcl12c/redo02.log
rm -f /disk1/digoal/oradata/orcl12c/redo03.log

alter database add logfile group 1 ('/disk1/digoal/oradata/orcl12c/redo01.log') size 2g;
alter database add logfile group 2 ('/disk1/digoal/oradata/orcl12c/redo02.log') size 2g;
alter database add logfile group 3 ('/disk1/digoal/oradata/orcl12c/redo03.log') size 2g;

修改benchmarksql建表SQL的ORACLE兼容性：

$  vi sqlTableCreates
create sequence benchmarksql.hist_id_seq;

create table benchmarksql.history (
  hist_id  integer default benchmarksql.hist_id_seq.nextval primary key,
  h_c_id   integer,
  h_c_d_id integer,
  h_c_w_id integer,
  h_d_id   integer,
  h_w_id   integer,
  h_date   timestamp,
  h_amount decimal(6,2),
  h_data   varchar(24)
);

创建表

$  cd benchmarksql/run
$  ./runSQL.sh props.ora sqlTableCreates

导入数据

$  nohup ./runLoader.sh props.ora numWarehouses 1000 >./load.log 2>&1 &

单位为50万。1000将写入5亿记录。

------------------------------------------------------

修改创建索引的脚本ORACLE兼容性。

删除以下无效SQL
-- select setval('hist_id_seq', (select max(hist_id) + 1 from benchmarksql.history), false);
-- vacuum analyze;
增加
exec dbms_stats.gather_schema_stats( - 
  ownname          => 'BENCHMARKSQL', - 
  options          => 'GATHER AUTO', - 
  estimate_percent => dbms_stats.auto_sample_size, -

  degree           => 34 - 
   );

创建索引

$  ./runSQL.sh props.ora sqlIndexCreates

手工修改序列值

SQL> select max(hist_id) + 1 from benchmarksql.history;
MAX(HIST_ID)+1
--------------
      30000001
SQL> select benchmarksql.hist_id_seq.nextval from dual;

  30000002
SQL>  alter sequence benchmarksql.hist_id_seq increment by 1;
Sequence altered.
SQL> select benchmarksql.hist_id_seq.nextval from dual;
   NEXTVAL

  30000003

benchmark 测试

修改runBenchmark.sh

$   vi runBenchmark.sh
java -cp .:$CLASSPATH:../lib/postgresql-9.3-1101.jdbc41.jar:../lib/log4j-1.2.17.jar:../lib/apache-log4j-extras-1.1.jar:../dist/BenchmarkSQL-4.1.jar -Dprop=$1 jTPCC

修改props.ora，设置比例。

$ vi props.ora
driver=oracle.jdbc.driver.OracleDriver
conn=jdbc:oracle:thin:@localhost:1521:orcl12c
user=benchmarksql
password=benchmarksql

warehouses=1000
terminals=96
//To run specified transactions per terminal- runMins must equal zero
runTxnsPerTerminal=0
//To run for specified minutes- runTxnsPerTerminal must equal zero
runMins=10
//Number of total transactions per minute
limitTxnsPerMin=0

//The following five values must add up to 100
newOrderWeight=40
paymentWeight=36
orderStatusWeight=8
deliveryWeight=8
stockLevelWeight=8

修改log4j，减少日志打印量。 priority改成info，只输出最终结果，不输出产生订单的日志。

$ vi log4j.xml

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

数据库没有做过多优化，测试数据仅供参考。

并且使用benchmarksql测试，系统还有大量空闲CPU，IO资源，所以性能应该不止于此。

有兴趣的童鞋可以使用load runner或者sysbench或其他工具再测试一下。

生成AWR：

压测开始前
BEGIN
  DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;
/

压测开始 到 结束。

BEGIN
  DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;

生成报告：
@$ORACLE_HOME/rdbms/admin/awrrpt.sql

为了突破测试程序的极限，开4个schema，每个schema负责1000个仓库，数据量总共20亿左右。

每个测试程序对付一个schema。

终端数保持一致，每个测试程序开32个终端，一共128个终端。
