在Oracle12.1中使用NID 修改数据库的DBID和DBName【实战】
短信预约 -IT技能 免费直播动态提醒
在异机恢复完成后,使用NID 修改数据库的DBID和DBName,重新启动数据库。
主要步骤如下:
1、 开启数据库:
SQL> startup
ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance
ORACLE instance started.
Total System Global Area 4.2950E+10 bytes
Fixed Size 4508576 bytes
Variable Size 2.6172E+10 bytes
Database Buffers 1.5569E+10 bytes
Redo Buffers 1203449856 bytes
Database mounted.
Database opened.
2、创建pfile,用于对DBName进行参数修改
SQL> create pfile from spfile;
3、查询当前的DBID和DBNAME
select name,dbid from v$database;
4、关闭数据库
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit
5、备份数据文件,尤其是控制文件
cp proddata data (简单进行冷备份)
6、将数据库启动到mount状态
[orapbf@erptest dbs]$ export ORACLE_SID=PROD
[orapbf@erptest dbs]$ echo $ORACLE_SID
PROD
[orapbf@erptest dbs]$sqlplus / as sysdba
SQL>startup mount;
7、查看nid命令简单帮助文档
[orapbf@erptest dbs]$ nid

8、使用nid修改dbid和DBName
[orapbf@erptest dbs]$ nid target=sys/oracle dbname=PBF

10、创建新的密码文件
orapwd file=/mnt/data/PBF/db/12.1.0/dbs/initPBF password=oracle format=12
11、使用resetlogs 选项打开数据库
[orapbf@erptest dbs]$ sqlplus / as sysdba
