1.物理Standby从SHUTDOWN状态启动到READ ONLY状态 ORCLPDG select open_mode from v$database; OPEN_MODE ---------- READ ONLY 启动之后默认是READ ONLY状态。 ORCLPDG alter database recover managed standby database cancel; alter database re

1.物理Standby从SHUTDOWN状态启动到READ ONLY状态
ORCLPDG >select open_mode from v$database;

OPEN_MODE
----------
READ ONLY
启动之后默认是READ ONLY状态。

ORCLPDG >alter database recover managed standby database cancel;
alter database recover managed standby database cancel
*
ERROR at line 1:
ORA-16136: Managed Standby Recovery not active

之前没有启动REDO应用,现在来取消此应用肯定会出错。
2.从READ ONLY状态到REDO应用状态
ORCLPDG >alter database recover managed standby database disconnect from session;

Database altered.

ORCLPDG >select open_mode from v$database;

OPEN_MODE
----------
MOUNTED
3.取消REDO应用,到READ ONLY状态
ORCLPDG >alter database recover managed standby database cancel;

Database altered.

ORCLPDG >select open_mode from v$database;

OPEN_MODE
----------
MOUNTED

ORCLPDG >alter database open;

Database altered.

ORCLPDG >select open_mode from v$database;

OPEN_MODE

READ ONLY

在Primary端删除表空间

including contents and datafiles在删除表空间的同时也自动删除对应的物理文件

好像已经删除了,但是看看操作系统下的物理文件:
ORCLPDG >host dir /u01/app/oracle/oradata/orclstd/*

ORCLPDG >host dir /u01/app/oracle/oradata/orclstd/*
/u01/app/oracle/oradata/orclstd/example01.dbf
/u01/app/oracle/oradata/orclstd/orclstd01.ctl
/u01/app/oracle/oradata/orclstd/orclstd02.ctl
/u01/app/oracle/oradata/orclstd/orclstd03.ctl
/u01/app/oracle/oradata/orclstd/pfile_orclstd.ora
/u01/app/oracle/oradata/orclstd/pri.dbf
/u01/app/oracle/oradata/orclstd/redo01.log

/u01/app/oracle/oradata/orclstd/undotbs01.dbf
/u01/app/oracle/oradata/orclstd/users01.dbf
可见,当standby_file_management=manual时,在Primary端删除时加上了including datafiles字句,Standby数据库

只会将表空间和数据文件从数据字典中删除,表空间涉及的物理文件需要手工删除。
重命名表空间:
ORCLPRE >alter tablespace rmantbs offline;

Tablespace altered.

ORCLPRE >host mv /u01/rec_catalog/rmantbs.dbf /u01/rec_catalog/rmantbs01.dbf

ORCLPRE >alter tablespace rmantbs online;
alter tablespace rmantbs online
*
ERROR at line 1:
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file
ORA-01110: data file 6: '/u01/rec_catalog/rmantbs.dbf'

由于在操作系统里面改过名字,无法识别。还要在数据字典里面修改数据文件路径。
ORCLPRE >alter tablespace rmantbs rename datafile
2 '/u01/rec_catalog/rmantbs.dbf'
3 to
4 '/u01/rec_catalog/rmantbs01.dbf';

Tablespace altered.
