SYS@rac2> alter system set log_archive_dest_1='LOCATION=+fra' scope=both sid='rac2';

2.關(guān)閉所有實(shí)例

shutdown immediate

3.設(shè)置歸檔

SYS@rac1> startup mount

SYS@rac1> alter database archivelog;

4.打開數(shù)據(jù)庫

SYS@rac1> alter database open;

5。兩個節(jié)點(diǎn)驗(yàn)證

節(jié)點(diǎn)1

SYS@rac1> archive log list

Database log mode Archive Mode

Automatic archival Enabled

Archive destination +FRA

SYS@rac2> archive log list

Database log mode Archive Mode

Automatic archival Enabled

Archive destination +FRA

Oldest online log sequence 29

ASMCMD [+FRA/rac/archivelog/2018_03_23] > ls

thread_1_seq_26.263.971545091

thread_2_seq_29.261.971544421

thread_2_seq_30.262.971545055

1關(guān)閉數(shù)據(jù)庫

[oracle@rac1 ~]$ srvctl stop database -d rac
