RAC veritabanlarında , veritabanı id ve veritabanı adının değiştirilmesi

Bu makalede RAC şeklinde çalışan bir veritabanının id ve adının değiştirilmesi , öncesinde ve sonrasında hangi işlemlerin yapılması gerektiği anlatılmaktadır.

Örneklerde ismi ORCL olan veritabanının adının TEST olarak değiştirilmesi için gerekli işlemler yapılmıştır.

Öncelikle cluster_database parametresinin değerini false olarak değiştirerek işe başlayalım.

Veritabanımızı bir node üzerinden mount modda başlatalım.

Yeni isimle oluşturulan veritabanı başlatalım.

-bash-4.3$  srvctl start database -d TEST
-bash-4.3$  srvctl status database -d TEST
Instance TEST1 is running on node oradb1
Instance TEST2 is running on node oradb2

CRS de eski isimle kayıtlı instance ve veritabanını silelim.

-bash-4.3$ srvctl remove instance -d ORCL -i ORCL1
Remove instance from the database ORCL? (y/[n]) y
-bash-4.3$ srvctl remove instance -d ORCL -i ORCL2
Remove instance from the database ORCL? (y/[n]) y
-bash-4.3$ srvctl remove database -d ORCL
Remove the database ORCL? (y/[n]) y

Bu aşamada , db_name ve db_unique_name parametreleri yeni isim olması beklenmektedir. ASM disk grupları içinde yeni isimle dizinler otomatik oluşması beklenmedir.

Veritabanımızı mount modda açıp, mevcut datafile’ların yeni ASM dizininde oluşmasını sağlayıp, eskilerini silelim.

Mevcut control_files parametresini , bir adet eski controlfile ve oluşmasını istediğimiz disk grupları isimlerini içerecek şekilde değiştirelim.

SQL> alter system set control_files='+DATA/orcl/controlfile/current.824.957891589','+DATA','+RECO' scope=spfile sid='*';

System altered.

Veritabanımızı nomount modda başlatıp , restore controlfile işlemi ile yeni controlfile’ların oluşmasını sağlayalım.

-bash-4.3$ srvctl stop database -d TEST


SQL> startup nomount

Daha önceki adımlarda spfile’ı ASM içindeki eski veritabanı adı altında yeni ismiyle oluşturmuştuk. Bu adımda yeni dizin altında yeni ismiyle tekrar oluşturacağız.

Spfile değişimi sonrasında veritabanı konfigürasyonu değiştirerek yeni spfile’ı kullanmasını sağlayalım.

-bash-4.3$ srvctl modify database -d TEST -p +DATA/test/spfiletest.ora
-bash-4.3$ srvctl config database -d TEST

Veritabanımızı kapatıp, tüm nodelardaki $ORACLE_HOME/dbs/initSID.ora dosyasındaki ilgili satırın bir önceki adımda veritabanı konfigürasyonunda belirttiğimiz spfile’ı gösterecek şekilde değiştirelim.

-bash-4.3$ srvctl stop database -d TEST


-bash-4.3$ cat $ORACLE_HOME/dbs/initTEST1.ora
SPFILE='+DATA/ORCL/spfileTEST.ora'              # line added by Agent


-bash-4.3$ vi $ORACLE_HOME/dbs/initTEST1.ora


-bash-4.3$ cat $ORACLE_HOME/dbs/initTEST1.ora
SPFILE='+DATA/test/spfiletest.ora'              # line added by Agent

Veritabanımızı açıp , konfigirasyonda yeni spfile’ın görüldüğünden ve yeni spfile ile açıldığından emin olalım.

-bash-4.3$ srvctl start database -d TEST
-bash-4.3$ srvctl config database -d TEST

ASMCMD> rm -rf ORCL

Son kontrollerimizi yapalım. Tüm datafile ve tempfile’ların ASM deki yeni dizin altında olduğundan emin olalım.
