前言

HammerDB 是一個開源的資料庫負載測試和基準測試工具，同時支援 Windows 和 Linux 平臺。

⛳️ 1. HammerDB簡介

HammerDB 是一個開源的資料庫負載測試和基準測試工具，同時支援 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。相比於標準的 TPC-C 和 TPC-H，HammerDB 執行成本低，操作簡單，是伺服器資料庫壓力測試
的很好選擇。
• HammerDB 通過模擬批發商的貨物管理環境，實現了 TPC-C 測試模型，即線上事務處理（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量，tpmC 是 TPC-C 的事務交易單位）。
• HammerDB 通過模擬供應商和採購商之間的交易行為，實現了 TPC-H 測試模型，即線上分析處理（OLAP）的基準測試模型。測試結果由 TPCH Power 來衡量，該值
與資料量和交易平均時間有關，表示一小時內能夠完成的複雜交易的數量。
關於 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 映象下載

docker pull techerwang/oracle:centos76

✨ 2.2 建立容器

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

⛳️3 . HammerDB壓測MySQL

1.如果是Windows直接點選hammerdb.bat，如果是Linux需要呼叫圖形化介面
2.windows平臺壓測，非常耗CPU

## 呼叫圖形化介面
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：生產環境壓測，建議倉庫數不少於100
