前言

HammerDB 是一個開源的數(shù)據庫負載測試和基準測試工具，同時支持 Windows 和 Linux 平臺。

?? 1. HammerDB簡介

HammerDB 是一個開源的數(shù)據庫負載測試和基準測試工具，同時支持 Windows 和 Linux 平臺，可以針對 Oracle 、SQL Server、DB2、TimesTen、 MySQL、MariaDB、
PostgreSQL、Postgres Plus Advanced Server、Greenplum、Redis、Amazon Aurora、Redshift 等進行壓力測試。
它主要模擬兩種不同的測試模型：TPC-C 測試模型和 TPC-H 測試模型。相比于標準的 TPC-C 和 TPC-H，HammerDB 運行成本低，操作簡單，是服務器數(shù)據庫壓力測試
的很好選擇。
• HammerDB 通過模擬批發(fā)商的貨物管理環(huán)境，實現(xiàn)了 TPC-C 測試模型，即在線事務處理（OLTP）的基準測試模型。測試結果由 TPC-C 吞吐率衡量，標準測試模型中
的單位是 tpmC（在在 B HammerDB 是中，測試結果的單位是 tpm，不是 tpmC。m tpm 表示每分鐘的事務交易數(shù)量，tpmC 是 TPC-C 的事務交易單位）。
• HammerDB 通過模擬供應商和采購商之間的交易行為，實現(xiàn)了 TPC-H 測試模型，即在線分析處理（OLAP）的基準測試模型。測試結果由 TPCH Power 來衡量，該值
與數(shù)據量和交易平均時間有關，表示一小時內能夠完成的復雜交易的數(shù)量。
關于 TPC-C 和 TPC-H 的詳細介紹請參考 TPC 官方網站（http://www.tpc.org/）

?? 2. 容器部署

? 2.1 鏡像下載

docker pull techerwang/oracle:centos76

? 2.2 創(chuàng)建容器

docker rm -f jemhammerdb

docker run -d --name jemhammerdb -h jemhammerdb \
-p 34389:3389 -p 42222:22 \
techerwang/oracle:centos76 init

docker exec -it jemhammerdb bash

? 2.3 Linux 下安裝

wget https://github.com/TPC-Council/HammerDB/releases/download/v4.0/HammerDB-4.0-Linux.tar.gz

[root@jeames ~]# tar -zxvf HammerDB-4.0-Linux.tar.gz -C /usr/local/
[root@jeames ~]# cd /usr/local/HammerDB-4.0
[root@jeames HammerDB-4.0]# ./hammerdbcli

??3 . HammerDB壓測MySQL

1.如果是Windows直接點擊hammerdb.bat，如果是Linux需要調用圖形化界面
2.windows平臺壓測，非常耗CPU

## 調用圖形化界面
export DISPLAY=192.168.1.1:0.0
echo $DISPLAY

[root@jeames ~]# cd /usr/local/HammerDB-4.0
[root@jemhammerdb HammerDB-4.0]# ./hammerdb

注：生產環(huán)境壓測，建議倉庫數(shù)不少于100
