解決方法:
1、檢查RAC節(jié)點(diǎn)的密碼文件是否同步,可以直接拷貝覆蓋一下
2、檢查DG節(jié)點(diǎn)的密碼文件是否同步, 可以直接拷貝RAC的密碼文件到DG覆蓋
3、在主節(jié)點(diǎn)alter system set log_archive_dest_state_2=enable;
4、再次查詢(xún)狀態(tài)變成VALID正常

然后再次檢查,發(fā)現(xiàn)還是不同步

主庫(kù)查看

備庫(kù)查看

log_archive_config string DG_CONFIG=(orcldbdg3,orcldbdg)

去主庫(kù)重新enable一下
alter system set log_archive_dest_state_2=ENABLE;
