如何從TFA升級到AHF?
前言:
Oracle
Autonomous Health Framework（AHF）將做為Oracle下一代健康檢測整合工具，這些工具可以24x7全天候自動協同工作，以保持資料庫系統的健康和運作，同時大幅度地減少人類的反應等待時間。Oracle應用機器學習技術，Oracle AHF可以提供預警或自動解決資料庫和系統管理員在高可用性(HA)和性能方面的運作問題。
通過以下方法，Oracle AHF可以在軟體（資料庫，GI，OS）和硬體（CPU，網絡，記憶體，儲存設備）問題期間保留資料庫系統的高可用性和效能：
A. 為潛在的高可用性(HA)或性能下降問題提供預警。
B. 快速識別瓶頸資源、重新分配資源、確定根本原因和AI建議採取的措施以快速解決。
C. 快速收集相關且完整的診斷log，可以上傳Oracle線上Support服務進行有效分類。
步驟:
1.
首先建立AHF安裝資料夾
[root@rac1
tmp]# mv AHF-LINUX_v19.3.2.zip /u01
[root@rac1
tmp]# cd /u01
[root@rac1
u01]# ls
AHF-LINUX_v19.3.2.zip app
[root@rac1
u01]# mkdir AHF
2.
解壓縮檔案
[root@rac1
u01]# unzip AHF-LINUX_v19.3.2.zip -d AHF
Archive: AHF-LINUX_v19.3.2.zip
inflating: AHF/README.txt
inflating: AHF/ahf_setup
3.
執行安裝程式
[root@rac1
u01]# cd AHF
[root@rac1
AHF]# ls
ahf_setup README.txt
[root@rac1
AHF]# ./ahf_setup
