正式生产库，配置双节点的RAC + 单实例的 DATAGUARD
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
正式生產(chǎn)庫，配置DATAGUARD
RAC+單實(shí)例DATAGUARD? 配置
RAC 兩節(jié)點(diǎn)：
192.1.0.101?? ?rac1?? ?
192.1.0.102?? ?rac2
存儲(chǔ)：ASM
DB_UNIQUE_NAME= racdb
實(shí)例：racdb1; racdb2;
DG:
192.1.0.103?? dg1?? ?
存儲(chǔ) ：ASM
數(shù)據(jù)庫名： racdb
DB_UNIQUE_NAME=stbdb;
一、系統(tǒng)準(zhǔn)備
?? ?1.1 DG 磁盤分區(qū)：
?? ?
?? ?本地磁盤，磁盤分區(qū)ASM DISK 對照表
?? ?磁盤分區(qū)?? ?磁盤大小?? ?RAID?? ?ASM NAME?? ?ASM GROUPDISKNAME
?? ?-----------------------------------------------------------------

?? ?/dev/sdb2?? ?300?? ??? ?GB?? ?RAID5?? ?RECOVERY2?? ?+RECOVERY

?? ?/dev/sdg1?? ?899.5?? ?GB?? ?RAID0?? ?DATA5?? ??? ?+DATA
?? ?/dev/sdb 為多個(gè)小盤合并成為一個(gè)RAID5的磁盤，因考慮到多個(gè)小盤（8*146G）多分區(qū)不好管理，
?? ?同時(shí)這幾個(gè)多個(gè)小盤已使用了2年左右，合并一起做RAID5也可以做個(gè)容錯(cuò)處理。
?? ?
?? ?1.2?? ?做一個(gè)SSH對待訪問
?? ?#在dg1上執(zhí)行建立私匙，以方便拷貝文件
?? ?# su - oracle
?? ?$ mkdir ~/.ssh
?? ?$ ssh-keygen -t rsa
?? ?$ ssh-keygen -t dsa
?? ?#將dg1的加入
?? ?$ ssh dg1 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
?? ?$ ssh dg1 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
?? ?$ scp ~/.ssh/authorized_keys dg1:~/.ssh/authorized_keys
?? ?（遇到一個(gè)問題：
?? ??? ?[oracle@rac1 .ssh]$ ssh dg1 date
?? ??? ?Warning: the RSA host key for 'dg1' differs from the key for the IP address '192.1.0.103'
?? ??? ?Offending key for IP in /home/oracle/.ssh/known_hosts:15
?? ??? ?Matching host key in /home/oracle/.ssh/known_hosts:17
?? ??? ?Are you sure you want to continue connecting (yes/no)? yes
?? ??? ?2013年 10月 12日 星期六 11:39:08 CST
?? ??? ?解決方法：
?? ??? ?查看known_hosts 內(nèi)容，發(fā)現(xiàn)'192.1.0.103' 以前指定了其它的服務(wù)器，直接刪除對應(yīng)的其它服務(wù)器行。
?? ??? ?問題解決。
?? ?）
?? ?還有一個(gè)有趣的問題，在RAC1中配置了ssh 對等訪問，系統(tǒng)會(huì)自動(dòng)更新到其它的RAC節(jié)點(diǎn)中，比如我這里有RAC2；
?? ?在單機(jī)上先安裝一個(gè)GRID（ASM),再安裝ORACLE.
?? ?1.3 安裝GRID
?? ??? ?【】為獨(dú)立服務(wù)器配置ORACLE GRID INFRASTRUCTURE
?? ??? ?安裝此項(xiàng)選擇，還要選擇一個(gè)ASM磁盤，是開始時(shí)沒想到的。后來另外分出兩個(gè)分區(qū)做ASM特征盤，
?? ??? ?有點(diǎn)象RAC中的RAC表決盤(或OCR磁盤）。
?? ?1.3，1.4 兩個(gè)安裝參考：

二、數(shù)據(jù)庫配置
?? ?
?? ?2.1 監(jiān)聽/ASM 配置
?? ?2.1.1 listener.ora
?? ?[oracle@localhost admin]$ cat listener.ora
?? ?# listener.ora Network Configuration File: /opt/app/oracle/product/11.2.0/network/admin/listener.ora
?? ?# Generated by Oracle configuration tools.
?? ?LISTENER =
?? ?? (DESCRIPTION_LIST =
?? ??? ?(DESCRIPTION =
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.103)(PORT = 1521))
?? ??? ?)
?? ?? )
?? ?2.1.2 tnsnames.ora
?? ?[oracle@localhost admin]$ cat tnsnames.ora
?? ?# tnsnames.ora Network Configuration File: /opt/app/oracle/product/11.2.0/network/admin/tnsnames.ora
?? ?# Generated by Oracle configuration tools.
?? ?RACDB1 =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS_LIST =
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.101)(PORT = 1521))
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.111)(PORT = 1521))
?? ??? ?)
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVICE_NAME = racdb)
?? ??? ?? (INSTANCE_NAME = racdb1)
?? ??? ?)
?? ?? )
?? ?RACDB =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan)(PORT = 1521))
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVER = DEDICATED)
?? ??? ?? (SERVICE_NAME = racdb)
?? ??? ?)
?? ?? )
?? ?RACDB2 =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS_LIST =
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.102)(PORT = 1521))
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.112)(PORT = 1521))
?? ??? ?)
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVICE_NAME = racdb)
?? ??? ?? (INSTANCE_NAME = racdb2)
?? ??? ?)
?? ?? )
?? ?stbdb =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.103)(PORT = 1521))
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVER = DEDICATED)
?? ??? ?? (SERVICE_NAME = stbdb)
?? ??? ?)
?? ?? )
?? ?把stbdb 部分插入到兩個(gè)節(jié)點(diǎn)的 tnsnames.ora 文件中。
?? ?
?? ?2.1.3 grid 用戶下，使用asmca 建立 +DATA,+RECOVERY 兩個(gè)ASM 磁盤組。
?? ??? ?測試查看ASM 磁盤組：
?? ??? ?[grid@localhost grid]$ asmcmd
?? ??? ?Connected to an idle instance.
?? ??? ?ASMCMD> ls
?? ??? ?ASMCMD-8102: no connection to ASM; command requires ASM to run
?? ??? ?
?? ??? ?修改grid 用戶下的.bash_profile
?? ??? ??? ?ORACLE_SID=+ASM; export ORACLE_SID?? ??? ? (原為：ORACLE_SID=+ASM1; 此內(nèi)容為RAC中拷貝而來有兩個(gè)實(shí)例ASM1,ASM2.)
?? ??? ??? ?PATH=$ORACLE_HOME/bin:$PATH; export PATH
?? ??? ??? ?
?? ?修改后問題解決：
?? ??? ?[grid@localhost grid]$ asmcmd
?? ??? ?ASMCMD> ls
?? ??? ?CRS/
?? ??? ?DATA/
?? ??? ?RECOVERY/
?? ??? ?ASMCMD> exit
?? ?2.2.配置參數(shù)：
?? ??? ?2.2.1、打開Forced Logging模式
?? ??? ?SQL> alter database force logging;
?? ??? ?Database altered.
?? ??? ?
?? ??? ?2.2.2
?? ??? ?SQL> alter system set log_archive_config='DG_CONFIG=(stbdb,racdb)';

?? ??? ?ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=stbdb LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=stbdb' scope=both;
?? ??? ?ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=DEFER;
?? ??? ?--先設(shè)置成不活動(dòng)的，后面再修改成：? ENABLE;
?? ??? ?--ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2 = ENABLE scope=both;
?? ??? ?#添加STANDBY LOGFILE:
?? ??? ?
?? ??? ?select group#,THREAD#,l.MEMBERS,l.STATUS from v$log l

?? ??? ?4?? ?4?? ?2?? ?2?? ?ACTIVE
?? ??? ?5?? ?5?? ?1?? ?2?? ?ACTIVE
?? ??? ?6?? ?6?? ?2?? ?2?? ?ACTIVE
?? ??? ? alter database add STANDBY logfile thread 1 group 7 ;
?? ??? ? alter database add STANDBY logfile thread 1 group 8 ;
?? ??? ? alter database add STANDBY logfile thread 1 group 9 ;
?? ??? ? alter database add STANDBY logfile thread 2 group 10 ;
?? ??? ? alter database add STANDBY logfile thread 2 group 11 ;
?? ??? ? alter database add STANDBY logfile thread 2 group 12 ;
?? ?#2.2 生成pfile，并修改。
?? ??? ?SQL> create pfile='/tmp/initstbdb.ora' from spfile;
?? ??? ?1.修改
?? ??? ??? ?*.audit_file_dest='/opt/app/oracle/admin/racdb/adump'
?? ??? ?? 修改后：
?? ??? ??? ?*.audit_file_dest='/opt/app/oracle/admin/stbdb/adump'
?? ??? ??? ?建立目錄 ：
?? ??? ??? ?mkdir -p /opt/app/oracle/admin/stbdb/adump
?? ??? ??? ?chown oracle:oinstall? /opt/app/oracle/admin/stbdb/adump
?? ??? ?2.添加以下內(nèi)容:

(紅色部分為添加的ASM 磁盤組)
?? ?1.3，1.4 兩個(gè)安裝參考：
?? ?http://blog.csdn.net/miyatang/article/details/6659839
?? ?
先前測試的配置日志（http://blog.csdn.net/miyatang/article/details/9979579）
二、數(shù)據(jù)庫配置
?? ?
?? ?2.1 監(jiān)聽/ASM 配置
?? ?2.1.1 listener.ora
?? ?[oracle@localhost admin]$ cat listener.ora
?? ?# listener.ora Network Configuration File: /opt/app/oracle/product/11.2.0/network/admin/listener.ora
?? ?# Generated by Oracle configuration tools.
?? ?LISTENER =
?? ?? (DESCRIPTION_LIST =
?? ??? ?(DESCRIPTION =
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.103)(PORT = 1521))
?? ??? ?)
?? ?? )
?? ?2.1.2 tnsnames.ora
?? ?[oracle@localhost admin]$ cat tnsnames.ora
?? ?# tnsnames.ora Network Configuration File: /opt/app/oracle/product/11.2.0/network/admin/tnsnames.ora
?? ?# Generated by Oracle configuration tools.
?? ?RACDB1 =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS_LIST =
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.101)(PORT = 1521))
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.111)(PORT = 1521))
?? ??? ?)
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVICE_NAME = racdb)
?? ??? ?? (INSTANCE_NAME = racdb1)
?? ??? ?)
?? ?? )
?? ?RACDB =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan)(PORT = 1521))
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVER = DEDICATED)
?? ??? ?? (SERVICE_NAME = racdb)
?? ??? ?)
?? ?? )
?? ?RACDB2 =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS_LIST =
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.102)(PORT = 1521))
?? ??? ?? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.112)(PORT = 1521))
?? ??? ?)
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVICE_NAME = racdb)
?? ??? ?? (INSTANCE_NAME = racdb2)
?? ??? ?)
?? ?? )
?? ?stbdb =
?? ?? (DESCRIPTION =
?? ??? ?(ADDRESS = (PROTOCOL = TCP)(HOST = 192.1.0.103)(PORT = 1521))
?? ??? ?(CONNECT_DATA =
?? ??? ?? (SERVER = DEDICATED)
?? ??? ?? (SERVICE_NAME = stbdb)
?? ??? ?)
?? ?? )
?? ?把stbdb 部分插入到兩個(gè)節(jié)點(diǎn)的 tnsnames.ora 文件中。
?? ?
?? ?2.1.3 grid 用戶下，使用asmca 建立 +DATA,+RECOVERY 兩個(gè)ASM 磁盤組。
?? ??? ?測試查看ASM 磁盤組：
?? ??? ?[grid@localhost grid]$ asmcmd
?? ??? ?Connected to an idle instance.
?? ??? ?ASMCMD> ls
?? ??? ?ASMCMD-8102: no connection to ASM; command requires ASM to run
?? ??? ?
?? ??? ?修改grid 用戶下的.bash_profile
?? ??? ??? ?ORACLE_SID=+ASM; export ORACLE_SID?? ??? ? (原為：ORACLE_SID=+ASM1; 此內(nèi)容為RAC中拷貝而來有兩個(gè)實(shí)例ASM1,ASM2.)
?? ??? ??? ?PATH=$ORACLE_HOME/bin:$PATH; export PATH
?? ??? ??? ?
?? ?修改后問題解決：
?? ??? ?[grid@localhost grid]$ asmcmd
?? ??? ?ASMCMD> ls
?? ??? ?CRS/
?? ??? ?DATA/
?? ??? ?RECOVERY/
?? ??? ?ASMCMD> exit
?? ?2.2.配置參數(shù)：
?? ??? ?2.2.1、打開Forced Logging模式
?? ??? ?SQL> alter database force logging;
?? ??? ?Database altered.
?? ??? ?
?? ??? ?2.2.2
?? ??? ?SQL> alter system set log_archive_config='DG_CONFIG=(stbdb,racdb)';
?? ??? ?SQL> ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=30;
?? ??? ?SQL> ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;
?? ??? ?SQL> ALTER SYSTEM SET FAL_SERVER=stbdb;
?? ??? ?SQL> alter system set FAL_CLIENT=racdb;
?? ??? ?SQL> alter system set standby_file_management=auto;
?? ??? ?ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=stbdb LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=stbdb' scope=both;
?? ??? ?ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=DEFER;
?? ??? ?--先設(shè)置成不活動(dòng)的，后面再修改成：? ENABLE;
?? ??? ?--ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2 = ENABLE scope=both;
?? ??? ?#添加STANDBY LOGFILE:
?? ??? ?
?? ??? ?select group#,THREAD#,l.MEMBERS,l.STATUS from v$log l
?? ??? ??? ?GROUP#?? ?THREAD#?? ?MEMBERS?? ?STATUS
?? ??? ?1?? ?1?? ?1?? ?2?? ?INACTIVE
?? ??? ?2?? ?2?? ?1?? ?2?? ?CURRENT
?? ??? ?3?? ?3?? ?2?? ?2?? ?CURRENT
?? ??? ?4?? ?4?? ?2?? ?2?? ?ACTIVE
?? ??? ?5?? ?5?? ?1?? ?2?? ?ACTIVE
?? ??? ?6?? ?6?? ?2?? ?2?? ?ACTIVE
?? ??? ? alter database add STANDBY logfile thread 1 group 7 ;
?? ??? ? alter database add STANDBY logfile thread 1 group 8 ;
?? ??? ? alter database add STANDBY logfile thread 1 group 9 ;
?? ??? ? alter database add STANDBY logfile thread 2 group 10 ;
?? ??? ? alter database add STANDBY logfile thread 2 group 11 ;
?? ??? ? alter database add STANDBY logfile thread 2 group 12 ;
?? ?#2.2 生成pfile，并修改。
?? ??? ?SQL> create pfile='/tmp/initstbdb.ora' from spfile;
?? ??? ?1.修改
?? ??? ??? ?*.audit_file_dest='/opt/app/oracle/admin/racdb/adump'
?? ??? ?? 修改后：
?? ??? ??? ?*.audit_file_dest='/opt/app/oracle/admin/stbdb/adump'
?? ??? ??? ?建立目錄 ：
?? ??? ??? ?mkdir -p /opt/app/oracle/admin/stbdb/adump
?? ??? ??? ?chown oracle:oinstall? /opt/app/oracle/admin/stbdb/adump
?? ??? ?2.添加以下內(nèi)容:
