資料檔案位置調整
今天，在做建立ORACLE GOLDENGATE測試資料庫時，將資料庫的資料檔案目錄放在了一個空間佔用比較大的盤上，需要調整過來。下面詳細記錄這一過程。
1、關閉資料庫
shutdown immediate
2、將資料庫的資料檔案移動到新位置
mv /u01/ora10g/oradata/ggtarget /u02/ora10g/oradata
3、啟動資料庫到nomount狀態
-bash-3.2$ export ORACLE_SID=ggtarge
-bash-3.2$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on 2 14:47:28 2010
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
Connected to an idle instance.
SQL> startup nomount
ORACLE instance started.
Total System Global Area 222298112 bytes
Fixed Size 1266680 bytes
Variable Size 75500552 bytes
Database Buffers 138412032 bytes
Redo Buffers 7118848 bytes
4、調整control_files引數，將重啟資料庫到mount狀態
SQL> show parameter control
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
control_file_record_keep_time integer
7
control_files string
/u01/ora10g/oradata/ggtarge/co
ntrol01.ctl, /u01/ora10g/orada
ta/ggtarge/control02.ctl, /u01
/ora10g/oradata/ggtarge/contro
l03.ctl
SQL> alter system set control_files='/u02/ora10g/oradata/ggtarge/control01.ctl, /u02/ora10g/oradata/ggtarge/control02.ctl, /u02/ora10g/oradata/ggtarge/control03.ctl' scope=both;
alter system set control_files='/u02/ora10g/oradata/ggtarge/control01.ctl, /u02/ora10g/oradata/ggtarge/control02.ctl, /u02/ora10g/oradata/ggtarge/control03.ctl' scope=both
*
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified
SQL> alter system set control_files='/u02/ora10g/oradata/ggtarge/control01.ctl, /u02/ora10g/oradata/ggtarge/control02.ctl, /u02/ora10g/oradata/ggtarge/control03.ctl' scope=spfile;
System altered.
SQL> select * from v$datafile;
select * from v$datafile
*
ERROR at line 1:
ORA-01507: database not mounted
SQL>
發現直接修改spfile，會給引數中帶來單引號，考慮修改pfile解決
SQL> show parameter control
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
control_file_record_keep_time integer
7
control_files string
/u02/ora10g/oradata/ggtarge/co
ntrol01.ctl, /u02/ora10g/orada
ta/ggtarge/control02.ctl, /u02
/ora10g/oradata/ggtarge/contro
l03.ctl
SQL> create pfile from spfile;
File created.
SQL> shutdown immediate
ORA-01507: database not mounted
ORACLE instance shut down.
編輯引數檔案/u01/ora10g/product/10.2.0/db_1/dbs/initggtarge.ora,修改引數：
*.control_files='/u02/ora10g/oradata/ggtarge/control01.ctl, /u02/ora10g/oradata/ggtarge/control02.ctl,/u02/ora10g/oradata/ggtarge/control03.ctl'
改為*.control_files=/u02/ora10g/oradata/ggtarge/control01.ctl, /u02/ora10g/oradata/ggtarge/control02.ctl,/u02/ora10g/oradata/ggtarge/control03.ctl
再次啟動資料庫到mount狀態：
SQL> startup mount pfile=/u01/ora10g/product/10.2.0/db_1/dbs/initggtarge.ora
ORACLE instance started.
Total System Global Area 222298112 bytes
Fixed Size 1266680 bytes
Variable Size 75500552 bytes
Database Buffers 138412032 bytes
Redo Buffers 7118848 bytes
Database mounted.
SQL> show parameter control
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
control_file_record_keep_time integer

control_files string
/u02/ora10g/oradata/ggtarge/co
ntrol01.ctl, /u02/ora10g/orada
ta/ggtarge/control02.ctl, /u02
/ora10g/oradata/ggtarge/contro
l03.ctl
SQL> create spfile from pfile;
File created.
5、修改資料檔案
SQL> desc dba_data_files;
ERROR:
ORA-04043: object dba_data_files does not exist
SQL> desc dba_datafiles;
ERROR:
ORA-04043: object dba_datafiles does not exist

SQL> alter database rename datafile '/u01/ora10g/oradata/ggtarge/system01.dbf' to '/u02/ora10g/oradata/ggtarge/system01.dbf';
alter database rename datafile '/u01/ora10g/oradata/ggtarge/system01.dbf' to '/u02/ora10g/oradata/ggtarge/system01.dbf'

f
/u02/ora10g/oradata/ggtarge/sysaux01.dbf
/u02/ora10g/oradata/ggtarge/users01.dbf
6、修改日誌檔案
SQL> desc v$logfile;
Name Null? Type
----------------------------------------- -------- ----------------------------
GROUP# NUMBER
STATUS VARCHAR2(7)
TYPE VARCHAR2(7)
MEMBER VARCHAR2(513)
IS_RECOVERY_DEST_FILE VARCHAR2(3)
SQL> col member for a40;

/u01/ora10g/oradata/ggtarge/redo02.log
/u01/ora10g/oradata/ggtarge/redo01.log
SQL> alter database rename file '/u01/ora10g/oradata/ggtarge/redo03.log' to '/u02/ora10g/oradata/ggtarge/redo03.log';

/u02/ora10g/oradata/ggtarge/redo02.log
/u02/ora10g/oradata/ggtarge/redo01.log
7、修改臨時檔案

2 ';
Database altered.
SQL> select * from v$tempfile;

READ WRITE 0 0 20971520 8192
/u02/ora10g/oradata/ggtarge/temp01.dbf
8、測試將資料庫啟動到OPEN狀態
SQL> alter database open;
Database altered.
SQL> select sysdate from dual;
SYSDATE
--------------
07-1210
OK，移動資料檔案位置後成功開啟資料庫
9、差點忘了，已經開了歸檔了，但是沒有設定歸檔目錄
SQL> show parameter archive;
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
archive_lag_target integer
0
log_archive_config string

------------------------------
enable
log_archive_dest_state_10 string
enable
log_archive_dest_state_2 string

------------------------------------ ----------------------
VALUE
------------------------------
enable
log_archive_duplex_dest string
log_archive_format string
%t_%s_%r.dbf

TRUE
log_archive_max_processes integer
2
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
log_archive_min_succeed_dest integer
1
log_archive_start boolean
FALSE
log_archive_trace integer
0
remote_archive_enable string
true
standby_archive_dest string
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
?/dbs/arch
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 1
Next log sequence to archive 1
Current log sequence 1
調整歸檔目錄：
SQL> alter system set log_archive_dest_1='location=/u02/ora10g/oradata/archive' scope=both;
alter system set log_archive_dest_1='location=/u02/ora10g/oradata/archive' scope=both
*
ERROR at line 1:
ORA-32001: write to SPFILE requested but no SPFILE specified at startup
SQL> alter system set log_archive_dest_1='location=/u02/ora10g/oradata/archive' scope=spfile;
alter system set log_archive_dest_1='location=/u02/ora10g/oradata/archive' scope=spfile
*
ERROR at line 1:
ORA-32001: write to SPFILE requested but no SPFILE specified at startup
看下是我剛剛以pfile啟動資料庫因此必須要將資料庫重新以spfile啟動後修改
SQL> startup nomount
ORACLE instance started.
Total System Global Area 222298112 bytes
Fixed Size 1266680 bytes
Variable Size 75500552 bytes
Database Buffers 138412032 bytes

SQL> alter system set log_archive_dest_1='location=/u02/ora10g/oradata/archive' scope=both;
System altered.
SQL> startup mount

SQL> alter database open;
alter database open
*

ORA-01507: database not mounted
SQL> alter database mount;
Database altered.
SQL> alter database open;
Database altered.
SQL> show parameter log_archive_dest_1
NAME TYPE
------------------------------------ ----------------------
VALUE
------------------------------
log_archive_dest_1 string
location=/u02/ora10g/oradata/a
rchive
log_archive_dest_10 string
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u02/ora10g/oradata/archive
Oldest online log sequence 1
Next log sequence to archive 2
Current log sequence 2
OK，所有需要調整的引數都已經調整過來
