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
DBNEWID: Release 12.1.0.2.0 - Production on Wed Mar 14 22:40:19 2018 Copyright (c) 1982, 2014, Oracle and/or its affiliates. All rights reserved. Keyword Description (Default) ---------------------------------------------------- TARGET Username/Password (NONE) DBNAME New database name (NONE) LOGFILE Output Log (NONE) REVERT Revert failed change NO SETNAME Set a new database name only NO APPEND Append to output log NO HELP Displays these messages NO
8、使用nid修改dbid和DBName
[orapbf@erptest dbs]$ nid target=sys/oracle dbname=PBF DBNEWID: Release 12.1.0.2.0 - Production on Wed Mar 14 22:41:41 2018 Copyright (c) 1982, 2014, Oracle and/or its affiliates.

[orapbf@erptest dbs]$ exit 登出
9、修改参数文件
[orapbf@erptest ~]$ cd $ORACLE_HOME/dbs [orapbf@erptest dbs]$ ls hc_PROD.dat initPROD.ora lkPROD snapcf_PROD.f spfilePROD.ora [orapbf@erptest dbs]$ vi initPROD.ora *.compatible='12.1.0' ... *.db_name='PBF' ... *._sort_elimination_cost_ratio=5 *._system_trig_enabled=TRUE *._TRACE_FILES_PUBLIC=FALSE *.aq_tm_processes=1 *.AUDIT_SYS_OPERATIONS=TRUE *.compatible='12.1.0' *.control_files='/mnt/data/PBF/db/proddata/cntrl01.dbf','/mnt/data/PBF/db/proddata/cntrl02.dbf','/mnt/data/PBF/db/proddata/cntrl03.dbf'#Restore Controlfile *.cursor_sharing='EXACT'# Required 11i settting *.db_block_checking='FALSE' *.db_block_checksum='TRUE' *.db_block_size=8192 *.db_files=512# Max. no. of database files *.db_name='PBF' *.db_recovery_file_dest_size=214748364800 *.db_recovery_file_dest='/mnt/data/PBF/db/db_recovery_dest' *.diagnostic_dest='/mnt/data/PBF/db/12.1.0/admin/PBF_erptest' *.dml_locks=10000 *.event='10995 trace name context forever, level 16' *.job_queue_processes=10 *.local_listener='PBF_LOCAL' *.log_archive_dest_1='LOCATION=/mnt/data/PBF/db/archive' "initPROD.ora" 76L, 2920C 已写入
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 SQL*Plus: Release 12.1.0.2.0 Production on Wed Mar 14 22:46:59 2018 Copyright (c) 1982, 2014, Oracle. All rights reserved. Connected to an idle instance.

SQL> alter database open resetlogs; SQL> select name,dbid from v$database; NAME DBID --------- ---------- PBF 2995320870 Database altered. sqlplus / as sysdba startup
12、创建新的spfile文件
create spfile from pfile;
