Disable Tfa In Oracle 19c RAC-20220112
導讀：
1.TFA是AHF（自主健康框架）的一部分，TFA可以幫助您收集和分析診斷資料。TFA從12.1.2.3.0之後封裝很多oracle問題分析工具。例如：ORAchk,EXchk,OSWatcher,Procwatcher,ORATOP,SQLT,DARDA,alert summary等等，這些工具都不用自行安裝了。
2.TFA生產系統中通常預估會佔用2%-5%cpu和2%-5%memory。故在不需要收集資訊的情況下我們是可以關閉的。
Oracle 19c Rac 關閉 Tfa 步驟如下：
1.檢查狀態
[root@rac1 ~]# tfactl status WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. .-------------------------------------------------------------------------------------------. | Host | Status of TFA | PID | Port | Version | Build ID | Inventory Status | +------+---------------+------+------+------------+----------------------+------------------+ | rac1 | RUNNING | 2186 | 5000 | 20.2.0.0.0 | 20200020200626072308 | COMPLETE | | rac2 | NOT RUNNING | - | | | | | | rac3 | NOT RUNNING | - | | | | | '------+---------------+------+------+------------+----------------------+------------------'
2.關閉自啟動
[root@rac1 ~]# tfactl disable WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. TFA autostart has been disabled ..
3.關閉tfa
[root@rac1 ~]# tfactl stop WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. Stopping TFA from the Command Line WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. Stopped OSWatcher Nothing to do ! TFA-00104 Cannot establish connection with TFA Server. Please check TFA Certificates Killing TFA running with pid 2186 . . . Successfully stopped TFA..
4.檢查是否關閉TFA
[root@rac1 ~]# tfactl status WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. TFA-00002 Oracle Trace File Analyzer (TFA) is not running # 已經關閉TFA
5.保證叢集節點統一配置管理，故其餘節點也執行關閉TFA操作
# rac2和rac3步驟省略，因過程和rac1節點相同
6.開啟tfa
# 先tfactl enable後，才能tfactl start [root@rac3 ~]# tfactl enable WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. TFA autostart has been enabled .. [root@rac3 ~]# tfactl start WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. Starting TFA.. Waiting up to 100 seconds for TFA to be started.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Successfully started TFA Process.. . . . . . WARNING - TFA Software is older than 180 days. Please consider upgrading TFA to the latest version. TFA Started and listening for commands
7.檢視tfa預設配置
