oracle 11g rac 恢复到单实例
一：在单实例上安装数据库软件不建数据库。
二：创建 initsid.ora文件
shell>cp cp /u01/app/oracle/product/11.2.0.3/dbhome_1/dbs/init{,sid}.ora
修改initsid.ora中的为他的路径
db_name='sid'
memory_target=1G
processes = 150
audit_file_dest='/u01/app/oracle/admin/sid/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
db_recovery_file_dest_size=15G # 恢复目录要足够大，不然的话在恢复的时候会报错。diagnostic_dest='/u01/app/oracle'
dispatchers='(PROTOCOL=TCP) (SERVICE=sidXDB)'
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
# You may want to ensure that control files are created on separate physical
# devices
control_files = (ora_control1, ora_control2)
compatible ='11.2.0'"/u01/app/oracle/product/11.2.0.3/dbhome_1/dbs/initsid.ora" 66L, 2856C written
二：创建恢复目录，将全备和归档日志解压放到该目录下：[oracle@ha1 ~]$ mkdir /u01/app/oracle/flash_recovery_area
[oracle@ha1 ~]$ mkdir /u01/app/oracle/admin
[oracle@ha1 ~]$ mkdir /u01/app/oracle/sid
[oracle@ha1 ~]$ mkdir /u01/app/oracle/sid/adump
[oracle@ha1 ~]$ vim /u01/app/oracle/product/11.2.0.3/dbhome_1/dbs/initsid.ora
# ghallmar 12/02/91 - add global_names=true, db_directory=us.acme.com
# thayes 11/27/91 - Change default for cache_clone
# jloaiza 08/13/91 - merge changes from branch 1.7.100.1
# jloaiza 07/31/91 - add debug stuff
# rlim 04/29/91 - removal of char_is_varchar2
# Bridge 03/12/91 - log_allocation no longer exists
