DM数据库学习之路(十九）DM8数据库sysbench部署及压力测试

sysbench部署

  ### **安装依赖**

yum -y install  make automake libtool pkgconfig libaio-devel vim-common

1. 上传sysbench源代码

sysbench_tool.tar

1. 测试是否安装成功

$ /opt/sysbench/sysbench-master-dpi/src/lua

$ ./sysbench --version

sysbench 1.1.0

sysbench测试DM

  ### **测试准备**

  1.

     #### **生成配置文件**

$cd /dmdata/sysbench_tool/sysbench-master-dpi

$ ./autogen.sh

autoreconf: Entering directory `.'

autoreconf: configure.ac: not using Gettext

autoreconf: running: aclocal -I m4

autoreconf: configure.ac: tracing

autoreconf: running: libtoolize --copy

libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, 'config'.

libtoolize: copying file 'config/ltmain.sh'

libtoolize: putting macros in AC_CONFIG_MACRO_DIRS, 'm4'.

libtoolize: copying file 'm4/libtool.m4'

libtoolize: copying file 'm4/ltoptions.m4'

libtoolize: copying file 'm4/ltversion.m4'

autoreconf: running: /usr/bin/autoconf

=============================================================================== 1. 1. 1. #### **编译** $ cd /dmdata/sysbench_tool/sysbench-master-dpi $ make 编译成功后，在src目录下生成可执行文件sysbench 将sysbench拷贝到src/lua目录下，然后进入/src/lua目录运行sysbench 1. 1. 1. #### **环境变量设置** export DM_HOME=/dm8 export PATH=$DM_HOME/bin:$PATH:$DM_HOME/tool:$PATH:HOME/bin:/usr/local/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$DM_HOME/bin sysbench测试的时候需要依赖dm的dpi驱动 需要设置：LD_LIBRARY_PATH 1. 1. 1. #### **DM默认测试脚本说明** sysbench的数据库测试脚本在src/lua目录下，以oltp为前缀，脚本是lua脚本，可以自行编辑，编辑保存后不需要编译就可以直接使用。 Internal目录下的lua脚本为基础生成h文件，供后续程序编译使用。修改Internal目录下的lua脚本需要重新编译sysbench脚本。 Oltp_common.lua：最基础的测试脚本，定义了表结构、事务基本操作。其它oltp脚本都是引用oltp_common，将其中query进行组合，实现各种测试场景。最常用3个脚本如下： oltp_read_write.lua:读写混合性测试，包含查询，更新，删除，插入操作 oltp_read_only.lua:读性能测试，包含查询操作 oltp_write_only.lua:写性能测试，包含更新、删除、插入操作 一般使用oltp_read_write.lua脚本测试数据库的oltp性能，包含了读和写操作。oltp_read_write.lua脚本qps是tps的20倍，一个transaction包含20个query操作，这20个query包含14个read，4个write,2个other. * begin:事务开始，计为1个other * point_selects:循环10次，计为10个read * simple_ranges:计为1个read * sum_ranges:计为1个read * order_ranges:计为1个read * distinct_ranger:计为1个read * index_updates: 计为1个write * non_index_updates: 计为1个write * delete_inserts:包含delete,insert操作，计为2个write * commit:事务结束，计为1个other oltp_read_write.lua脚本说明： **require** **部分：**引用其它lua脚本。Oltp_read_write.lua脚本中的函数定义都在oltp_common.lua脚本，所以需要首先引用。 **Prepare_statements** **部分：**对应sysbench测试执行过程中run命令的initializing worker threads部分，对数据库的操作就是建立session后准备各种操作的语句句柄和参数绑定。 **Event** **部分：**这部分是测试执行的具体步骤，对应与sysbench的测试执行过程中run命令在threads started后开始的操作。反复执行event统计各种指标。 1. 1. ### **DM8测试** 1. #### **基本测试** 1. #####

**连接失败，错误代码DM_-70089** **错误信息:** ALERT:Error -- DM_-70089_Encryption module failed to load **错误** **原因：** Sysbench测试DM时，未找到所依赖的dm动态库 **解决方法：** 在sysbench终端，设置LD_LIBRARY_PATH,添加dm的bin目录，或者将dm的bin目录下的动态库拷贝到系统目录。 1. 1. 1. #### **连接成功，测试线程初始化失败，错误代码DM_-606** **错误信息:** DM_-606_stmt handle to the limit the number of statements or system of memory **错误** **原因：** Session上的句柄限制，需要调大句柄。例：1个事务仅有2个query,测试表共计25个，每个session要申请2\*25=50个句柄用于测试。默认的oltp_read_write.lua脚本中1个事务有11个query,25张测试表默认即11\*25=275个语句句柄。 **解决方法：** vi dm.ini 增加MAX_SESSION_STATEMENT 1. 1. 1. #### **执行configure失败** **错误信息:** configure error:mysql_config executable not found **错误** **原因：** 编译支持mysql的sysbench时，没有找到mysql的头文件和驱动。 **解决方法：** 如果不需要支持mysql测试，那么configure使用参数---without-mysql. 如果需要支持mysql测试，那么需要安装mysql-devel软件包，configure使用参数---with-mysql-includes指定mysql头文件目录,--with-mysql-libs指定libmysqlclient.so文件目录。例如 ./configure --with-mysql-includes=/usr/include/mysql --with-mysql-libs=/usr/lib64/mysql/ 1. 1. 1. #### **测试DM，连接成功，测试线程初始化失败** **错误信息:** 无效的表或者视图名 **错误** **原因：** 没有完成建表和数据插入或者sysbench run使用的参数---tables同prepare过程中使用的---tables参数不一致 **解决方法：** 先完成建表和数据插入，确认sysbench run使用的参数---tables同prepare过程中使用的---tables参数一致。 1. 1. 1. #### **测试DM，连接失败** **错误信息:** 当前session超过最大值 **错误** **原因：** 当前测试数据库连接threads=1000超过dm.ini中MAX_SESSIONS最大值 **解决方法：** 修改数据库dm.ini中MAX_SESSION值 1. 1. 1. #### **测试DM，测试线程初始化失败** **错误信息:** FATAL:worker threads failed to initialize within 30 seconds **错误** **原因：** Sysbench测试中，测试线程初始化的默认时间超过了初始化参数时间值，如--time=30，当遇到网路延时，测试表多，测试线路程较多，一旦超过30秒，就会出现上述错误。 **解决方法：** --thread-init-timeout来设置一个合适 的初始化超时时间。 1. 1. 1. #### **测试DM，并发大测试表多，初始化失败** **错误信息:** Error -- DM_-70019 **错误** **原因：** Dmserver同时处理太多连接请求，导致每个连接处理耗时增加，后续连接超时。 **解决方法：** vi dm.ini增加参数STARTUP_TIMEOUT=500 注：STARTUP_TIMEOUT表示dpi_login发startup和login消息给服务器之间的超时时间。
