生活随笔收集整理的這篇文章主要介紹了 Oracle自治事务处理数据库OCPU可扩展性测试小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

簡介

本文是Autonmous Transaction Processing的操作過程。

創建云實例并安裝Swing Bench

建立yum metadata cache：

$ sudo yum makecache fast Loaded plugins: langpacks, priorities, ulninfo, versionlock ol7_UEKR5 | 2.8 kB 00:00 ol7_addons | 2.8 kB 00:00 ol7_developer | 2.8 kB 00:00 ol7_developer_EPEL | 3.4 kB 00:00 ol7_developer_golang113 | 2.8 kB 00:00 ol7_developer_nodejs10 | 2.8 kB 00:00 ol7_developer_php72 | 2.8 kB 00:00 ol7_ksplice | 2.8 kB 00:00 ol7_latest | 3.4 kB 00:00 ol7_oci_included | 2.9 kB 00:00 ol7_optional_latest | 2.8 kB 00:00 ol7_oracle_instantclient | 2.8 kB 00:00 ol7_software_collections | 2.8 kB 00:00 : ol7_software_collections/x86_64/primary_db | 4.8 MB 00:00 Metadata Cache Created

安裝JDK:

$ sudo yum install java-1.8.0-openjdk-headless.x86_64 Loaded plugins: langpacks, priorities, ulninfo, versionlock 9 packages excluded due to repository priority protections Excluding 2 updates due to versionlock (use "yum versionlock status" to show them) Package 1:java-1.8.0-openjdk-headless-1.8.0.232.b09-0.el7_7.x86_64 already installed and latest version Nothing to do

安裝swingbench：

curl http://www.dominicgiles.com/swingbench/swingbenchlatest.zip -o swingbench.zip unzip swingbench.zip cd swingbench

創建 ATP實例并利用Swing Bench導入數據

創建一個自治交易數據庫ATPDB，過程略。
下載Client Credentials，文件名為wallet_ATPDB.zip，并上傳到剛才創建的云實例中。目標目錄為默認，即opc用戶的home目錄(/home/opc)。

$ unzip -l wallet_ATPDB.zip Archive: wallet_ATPDB.zipLength Date Time Name --------- ---------- ----- ----6733 12-23-2019 03:09 cwallet.sso1851 12-23-2019 03:09 tnsnames.ora3335 12-23-2019 03:09 truststore.jks301 12-23-2019 03:09 ojdbc.properties114 12-23-2019 03:09 sqlnet.ora6688 12-23-2019 03:09 ewallet.p123275 12-23-2019 03:09 keystore.jks --------- -------22297 7 files

在目標數據庫中創建schema并導入數據，挺快，2分多鐘：

配置Swing Bench負載生成器

cd ~/swingbench/configs vi SOE_Server_Side_V2.xml

做如下修改并保存：

... <LogonGroupCount>4</LogonGroupCount> ... <LogonDelay>300</LogonDelay> ... <WaitTillAllLogon>false</WaitTillAllLogon> ...

確認：

$ grep Logon SOE_Server_Side_V2.xml<LogonGroupCount>4</LogonGroupCount><LogonDelay>300</LogonDelay><WaitTillAllLogon>false</WaitTillAllLogon>

生成負載：

cd ~/swingbench/bin ./charbench -c ../configs/SOE_Server_Side_V2.xml -cf ~/wallet_ATPDB.zip -cs ATPDB_medium -u soe -p $DB_PASSWORD -v users,tpm,tps,vresp -intermin 0 -intermax 0 -min 0 -max 0 -uc 128 -di SQ,WQ,WA -rt 0:30.30

然后輸出如下，其中第3列是TPM，第4列是TPS：

將ATPDB的OCPU由1調整到4，然后TPS和TPM大約變為以前的4倍：

最后清理環境。

遺留問題

第一個問題是，Auto Scaling是默認開啟的，為何沒有自動由1變為4？

第二個問題，Number of OCPUs allocated需要在Service Console中看，但只顯示1。是不是表示，雖然我分配了4，但實際只用到1呢？
后來發現是需要等一段時間，才會在圖上反映。
