Oracle：获取创建控制文件的指令

有时候可能出于好奇或者重建控制文件等需求，需要获取当前数据库的控制文件创建时的语句。
这种时候你需要通过TRACE获取。

以下初步呈现技术细节。
Trace存放路径：

[oracle@ora12c ~]$ pwd
/home/oracle
[oracle@ora12c ~]$ ls -ltr
total 8
-rw-r--r-- 1 oracle oinstall 4781 Nov  2 21:40 db_logic.xml
[oracle@ora12c ~]$

[oracle@ora12c ~]$ pwd

/home/oracle

[oracle@ora12c ~]$ ls -ltr

total 8

-rw-r--r-- 1 oracle oinstall 4781 Nov 2 21:40 db_logic.xml

[oracle@ora12c ~]$

SQL*Plus操作：

[oracle@ora12c ~]$ ps -ef | grep pmon
oracle   39387     1  0 13:01 ?        00:00:00 ora_pmon_atlas
oracle   39561 39474  0 13:27 pts/2    00:00:00 grep pmon
[oracle@ora12c ~]$ env | grep SID
ORACLE_SID=atlas
[oracle@ora12c ~]$
[oracle@ora12c ~]$ sqlplus / as sysdba

[oracle@ora12c ~]$

注意，上面的“alter database backup controlfile …”最后跟的参数是“noresetlogs”。
它的意义是不重置联机重做日志。
如果需要重置联机重做日志，可以将“noresetlogs”修改为“resetlogs”。

默认情况下，如果不跟“noresetlogs”或“resetlogs”，在生成的TRACE文件中会包含两条“Create controlfile”的语句，分别对应以上两个选项。
在选择的时候需要小心甄别。

查看生成的TRACE文件：
