Linux 安裝 Oracle 11g——手工建庫（RAC）



1. 創建目錄
   mkdir -p /u01/app/oracle/admin/orcl/adump
2. 編輯參數文件
   *.memory_target=512m
   *.audit_file_dest='/u01/app/oracle/admin/orcl/adump'
   *.audit_trail='db'
   *.control_files=’+DATADG/ORCL/controlfile/control01.ctl’, ‘+DATADG/ORCL/controlfile/control02.ctl’                                           
   *.db_block_size=8192
   *.db_create_file_dest='+DATADG'
   *.db_domain=''
   *.db_name='orcl'
   *.db_recovery_file_dest='+DATADG'
   *.db_recovery_file_dest_size=1G
   *.diagnostic_dest='/u01/app/oracle'
   *.open_cursors=300
   *.processes=150
   *.remote_listener='nodescan:1521'
   *.remote_login_passwordfile='exclusive'
3. 創建ASM目錄和創建spfile
   • 創建spfile路徑
     [grid@node1 ~]$ asmcmd
     ASMCMD> cd DATADG
     ASMCMD> mkdir ORCL
     
     
   • 開啓第一個節點
     [grid@node1 ~]$ sqlplus / as sysdba 
     SQL> create spfile='+DATADG/ORCL/spfileorcl.ora' from pfile='/tmp/1.txt';
     
     
   • 創建init文件
     
     • 節點1
       vi initorcl1.ora
       SPFILE='+DATADG/ORCL/spfileorcl.ora'
     • 節點2
       vi initorcl2.ora
       SPFILE='+DATADG/ORCL/spfileorcl.ora'
4. 創建密碼文件
   cd $ORACLE_HOME/dbs
   節點1：orapwd file=orapwORCL1 password=oracle
   節點2：orapwd file=orapwORCL2 password=oracle
5. 創建DB
   CREATE DATABASE orcl
      USER SYS IDENTIFIED BY oracle
      USER SYSTEM IDENTIFIED BY oracle
      LOGFILE GROUP 1 ('+DATADG') SIZE 100M,
              GROUP 2 ('+DATADG') SIZE 100M,
              GROUP 3 ('+DATADG') SIZE 100M
      MAXLOGFILES 5
      MAXLOGMEMBERS 5
      MAXLOGHISTORY 1
      MAXDATAFILES 100
      CHARACTER SET US7ASCII
      NATIONAL CHARACTER SET AL16UTF16
      EXTENT MANAGEMENT LOCAL
      DATAFILE '+DATADG' SIZE 325M
      SYSAUX DATAFILE '+DATADG' SIZE 325M
      DEFAULT TABLESPACE users
         DATAFILE '+DATADG'
         SIZE 500M  AUTOEXTEND ON MAXSIZE UNLIMITED
      DEFAULT TEMPORARY TABLESPACE tempts1
         TEMPFILE '+DATADG'
         SIZE 20M
      UNDO TABLESPACE undotbs1
         DATAFILE '+DATADG'
         SIZE 200M  AUTOEXTEND ON MAXSIZE UNLIMITED;
6. 創建undo 和添加redo
   • UNDO
     CREATE UNDO TABLESPACE UNDOTBS2 DATAFILE '+DATADG' SIZE 200M;
   • REDO
     ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 4 '+DATADG' SIZE 100M; 
     ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 5 '+DATADG' SIZE 100M;
     ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 6 '+DATADG' SIZE 100M; 
7. 以下轉單實例db到RAC DB
   
   • 添加rac 參數 
     *.cluster_database=true
     orcl1.instance_number=1
     orcl2.instance_number=2
     orcl2.thread=2
     orcl1.thread=1
     orcl1.undo_tablespace='UNDOTBS1'
     orcl2.undo_tablespace='UNDOTBS2'
   • 啓動第一節點
     startup
     
     ALTER DATABASE ENABLE PUBLIC THREAD 2;
     
     
   • 啓動第二節點數據庫
     startup
     
     
   • 驗證
     select instance_name from gv$instance;
     
     
8. 執行創建數據字典腳本
   @?/rdbms/admin/catalog.sql
   @?/rdbms/admin/catproc.sql
   @?/rdbms/admin/catclust.sql
   @?/rdbms/admin/utlrp.sql
9. 註冊數據庫到Clusterware
   
   • 註冊
     srvctl add database -d orcl -o $ORACLE_HOME
     srvctl add instance -d orcl -i orcl1 -n node1
     srvctl add instance -d orcl -i orcl2 -n node2
     srvctl enable database -d orcl
     srvctl start database -d orcl
     
     
   • 驗證
     crsctl stat res -t
