Oracle veritabanını başka bir alana taşıma

1.AMAÇ VE KAPSAM

Oracle controlfile, logfile ve datafile taşıma işlemi

2.UYGULAMA

2.1. Control file’ın lokasyonunu değiştirme.

2.1.1 Control file şuanki lokasyonunu buluyoruz.

SQL> select name from v$controlfile;

NAME

————————————————————-

/U01/APP/ORACLE/ORADATA/CONTROL01.CTL

/U01/APP/ORACLE/ORADATA/CONTROL02.CTL

/U01/APP/ORACLE/ORADATA/CONTROL03.CTL

3 rows selected.

SQL>

2.1.2. Direk lokasyona mv scriptini hazırlamak için. (dosyanın tutulduğu lokasyona göre substr nin ayarlanması gerekir)

SQL> select ‘ mv ‘|| name || ‘ /yeni_disk/’ || substr(name,30) from v$controlfile;

‘MV’||NAME||’/YENI_DISK/’||SUBSTR(NAME,30)||”

——————————————————————————–

mv /u01/app/oracle/oradata/orcl/control01.ctl /yeni_disk/control01.ctl

mv /u01/app/oracle/oradata/orcl/control02.ctl /yeni_disk/control02.ctl

mv /u01/app/oracle/oradata/orcl/control03.ctl /yeni_disk/control03.ctl

2.1.3. Control file’ın lokasyonunu spfile üstünde değiştiriyoruz.

SQL> ALTER SYSTEM SET control_files=’/u02/app/oracle/oradata/controlfile/CONTROL01.CTL’, ‘/u02/app/oracle/oradata/controlfile/CONTROL02.CTL’,’/u02/app/oracle/oradata/controlfile/CONTROL03.CTL’ SCOPE=SPFILE;

Database altered.

2.1.4. Veritabanını kapatıp controlfile’ları yeni lokasyonlarına taşıyoruz.

SQL> SHUTDOWN IMMEDIATE

Database closed.

Database dismounted.

ORACLE instance shut down.

$ mv /U01/APP/ORACLE/ORADATA/CONTROL03.CTL /u02/app/oracle/oradata/controlfile/CONTROL03.CTL

2.1.5. Sistemi yeniden açıyoruz.

SQL> STARTUP

SQL> select ‘ mv ‘|| member || ‘ /yeni_disk/’ || substr(member,30) from v$logfile;

‘MV’||MEMBER||’/YENI_DISK/’||SUBSTR(MEMBER,30)||”

$ mv /U01/APP/ORACLE/ORADATA/REDO/REDO01.LOG /u02/app/oracle/oradata/redo/REDO01.LOG

2.2.5. Direk lokasyonu scriptle değiştirip komutu hazırlamak için. (dosyanın tutulduğu lokasyona göre substr nin ayarlanması gerekir)

SQL> select ‘ ALTER DATABASE RENAME FILE ”’|| member || ”’ to ”/yeni_disk/’ || substr(member,30) || ”’;’ from v$logfile;

‘ALTERDATABASERENAMEFILE”’||MEMBER||”’TO”/YENI_DISK/’||SUBSTR(MEMBER,30)||”’

disk/redo03.log’;

ALTER DATABASE RENAME FILE ‘/u01/app/oracle/oradata/orcl/redo02.log’ to ‘/yeni_

disk/redo02.log’;

ALTER DATABASE RENAME FILE ‘/u01/app/oracle/oradata/orcl/redo01.log’ to ‘/yeni_

disk/redo01.log’;
