1）dbca建库

1）tnsnames配置（主备）
su - oracle vi $(orabasehome)/network/admin/tnsnames.ora tns_albin = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.150.10.135)(PORT = 1625)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = albin) ) ) tns_albindg = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.150.10.140)(PORT = 1625)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = albindg) (UR = A) ) )
2）配置监听
-- 主备添加dg监听器
su - grid srvctl add listener -listener LSNR_DG -endpoints "TCP:1625" srvctl start listener -listener LSNR_DG
-- 备库添加静态监听 vi $(orabasehome)/network/admin/listener.ora SID_LIST_LSNR_DG = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = albindg) (ORACLE_HOME = /oracle/app/12.2.0/grid) (SID_NAME = albin1) ) (SID_DESC = (GLOBAL_DBNAME = albindg_DGMGRL) (ORACLE_HOME = /oracle/app/12.2.0/grid) (SID_NAME = albin1) ) )
注：其它节点实例按实际情况修改标红处内容
1）查看密码文件路径
$ srvctl config database -d albin Database unique name: albin Database name: albin Oracle home: /oracle/app/oracle/product/12.2/db_1 Oracle user: oracle Spfile: +DATA/ALBIN/PARAMETERFILE/spfile.1328.982582089 Password file: +DATA/ALBIN/PASSWORD/pwdalbin.1312.982581307 Domain: Start options: open
2）复制密码文件到备端服务器
拷贝密码文件到文件系统并传到备端服务器 方案1： su - oracle sqlplus "/ as sysdba" create or replace directory source_dir as ‘+data/albin/password‘; create or replace directory dest_dir as ‘/tmp‘; set lines 168 pages 99 col DIRECTORY_NAME for a32 col owner for a18 col DIRECTORY_PATH for a80 select owner, DIRECTORY_NAME, DIRECTORY_PATH,ORIGIN_CON_ID from dba_directories; begin dbms_file_transfer.copy_file( source_directory_object => ‘source_dir‘, source_file_name => ‘pwdalbin.1312.982581307‘, destination_directory_object => ‘dest_dir‘, destination_file_name => ‘orapwalbin‘); end; / SQL> host ls -l /tmp/orapwalbin 方案2: su - grid asmcmd cd data/albin/password cp pwdalbin.1312.982581307 /tmp/orapwalbin -- 备端服务器节点
scp /tmp/orapwalbin grid@vm-ora-N1:/tmp/orapwalbin
su - grid
asmcmd -exec "cp /tmp/orapwalbin +data/albindg/password/orapwalbin"

host scp /home/oracle/stdby.ora oracle@vm-ora-N1:/home/oracle/stdby.ora
对物理备库创建备重做日志文件,查询主库的联机重做日志文件，备重做日志文件的大小应该与主库联机重做日志文件的大小相同，备重做日志文件组的数量应该比主库联机重做日志文件组多一组，计算公式为(maximum # of logfiles +1) * maximum # of threads (实际：standby_redo_logs = 主库日志组+1，成员数量一致)
注意：RAC数据库，在创建重做日志文件时需要指定thread号
