1.Primary数据库生成LogMiner字典信息（生成之前，确保待转换的物理Standby停止REDO应用）
ORCLPRI_LG >execute dbms_logstdby.build;
PL/SQL procedure successfully completed.
2.逻辑Standby更名
ORCLSTD_LG >show parameter db_name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_name string orcl
ORCLSTD_LG >alter database recover to logical standby ORCLLDG;
alter database recover to logical standby ORCLLDG
*
ERROR at line 1:
ORA-19953: database should not be open
ORCLSTD_LG >shutdown immediate
ORA-01507: database not mounted
ORACLE instance shut down.
ORCLSTD_LG >alter database recover to logical standby ORCLLDG;
alter database recover to logical standby ORCLLDG
*
ERROR at line 1:
ORA-01034: ORACLE not available
ORCLSTD_LG >startup mount
ORACLE instance started.

3.重启生效
ORCLSTD_LG >show parameter db_name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_name string ORCLLDG
ORCLSTD_LG >select database_role from v$database;
DATABASE_ROLE
----------------
LOGICAL STANDBY
4.创建本地和远程归档路径
