ORACLE-PDB管理-CBD数据库控制文件

  在节点1连接数据库，直接连接到cdb$root,执行转储当前的控制文件到/home/oracle/123.ctl中，分析对于容器数据库oracle。控制文件的结构是什么样的进行分析：

1 转储控制文件

sqlplus / as sysdba
alter database backup controlfile to trace as '/home/oracle/123.txt'

2 读取控制文件

[oracle@wxdb02 ~]$ more 123.ctl

-- Below are two sets of SQL statements, each of which creates a new
-- control file and uses it to open the database. The first set opens
-- the database with the NORESETLOGS option and should be used only if
-- the current versions of all online logs are available. The second
-- set opens the database with the RESETLOGS option and should be used
-- if online logs are unavailable.
-- The appropriate set of statements can be copied from the trace into
-- a script file, edited as necessary, and executed when there is a
-- need to re-create the control file.
--
--     Set #1. NORESETLOGS case
--
-- The following commands will create a new control file and use it
-- to open the database.
-- Data used by Recovery Manager will be lost.
-- Additional logs may be required for media recovery of offline
-- Use this only if the current versions of all online logs are
-- available.

-- After mounting the created controlfile, the following SQL
-- statement will place the database in the appropriate
-- protection mode:
--  ALTER DATABASE SET STANDBY DATABASE TO MAXIMIZE PERFORMANCE
