背景:
資料庫建設到現在,一緻在做邏輯備份,考慮到後期維護人員現場情況,建議最近就将歸檔日志打開
過程
因為之前沒有在rac開啟過歸檔,現在在虛拟rac下測試下如果歸檔路徑放到某個節點,或者放到存儲中
grid>asmcmd
>ls
cd DATADG/
cd arch
mkdir arch
pwd
SQL> alter system set log_archive_dest_1='location=+DATADG/arch' scope=spfile sid='*';
System altered.
關閉資料庫,全部節點都要關閉
[grid@zhcs-db1 ~]$ srvctl stop database -d PROD
srvctl stop database -d PROD
srvctl start database -d PROD -o mount

實戰中
節點二的叢集關閉,高可用關閉,後來重新啟動都在報錯,是在沒招了,重新開機了節點二機器,重新開機後發現資料庫還在重新開機中,但是叢集已經啟動了
