SYS@oradb1>create spfile='+DATADG/oradb_s/spfileoradb.ora' from pfile='/home/oracle/init_s.ora'; cd $ORACLE_HOME/dbs echo "SPFILE='+DATADG/oradb_s/spfileoradb.ora'" > initoradb1.ora cd $ORACLE_HOME/dbs echo "SPFILE='+DATADG/oradb_s/spfileoradb.ora'" > initoradb2.ora备库启动到nomount状态 SYS@oradb1>startup nomount;

alter system set log_archive_config='dg_config=(oradb,oradb_s)' scope=spfile sid='*'; alter system set log_archive_dest_1='location=+FRA valid_for=(all_logfiles,all_roles) db_unique_name=oradb' scope=spfile sid='*';

alter system set log_archive_dest_state_2=enable scope=spfile sid='*'; alter system set standby_file_management='auto' scope=spfile sid='*'; alter system set fal_server='oradb_s' scope=spfile sid='*'; alter system set db_file_name_convert='+DATADG/ORADB_S','+DATADG/ORADB' scope=spfile sid='*'; alter system set log_file_name_convert='+DATADG/ORADB_S','+DATADG/ORADB' scope=spfile sid='*';重启主库 srvctl stop database -d oradb srvctl start database -d oradb 7. 主库添加standby日志 alter database add standby logfile thread 1 group 7 '+DATADG' size 100M; alter database add standby logfile thread 1 group 8 '+DATADG' size 100M; alter database add standby logfile thread 1 group 9 '+DATADG' size 100M; alter database add standby logfile thread 1 group 10 '+DATADG' size 100M;

restore database; switch datafile all; release channel t1; release channel t2; } 9. 注册OCR并打开备库 srvctl add database -d oradb -o $ORACLE_HOME srvctl add instance -d oradb -i oradb1 -n oradg1 srvctl add instance -d oradb -i oradb2 -n oradg2 SYS@oradb1>shutdown immediate $ srvctl start database -d oradb -o 'read only' 10. 备库应用日志 SYS@oradb1>alter database recover managed standby database using current logfile disconnect from session;
