ADG 升级 [11.2.0.1 -> 11.2.0.4]
目标
ORACLE ADG 环境下将 11.2.0.1 升级到 11.2.0.4
思路
停快速故障轉移功能;主库暂停归档传输;备库安装新版本软件,备库启动到mount;主库安装软件,主库升级数据库,主库启用归档传输,备库开启日志恢复。
注意
11.2.0.4新版软件安装到一个新目录下，注意copy之前的spfile、密码文件、network file、dg_broker_config文件（监听配置文件的静态监听部分需要修改），备库只升级软件版本。数据库升级是通过主库升级后通过应用主库归档完成升级和同步的。
概要步骤
1.停快速故障轉移功能
2.主库暂停归档向备库传输
3.备库在新目录下安装新版本软件
4.备库启动到mount状态
5.主库安装软件，升级数据库
6.主库启用归档向备库传输
7.检查备库、主库升级情况
8.修改 compatible 参数(主备)
9.ADG环境DB重启
10.切换到最大可用模式
具体步骤
1.停快速故障轉移功能
[oracle@mppay2 ~]$ dgmgrl sys/123456
DGMGRL> show configuration
DGMGRL>stop observer
DGMGRL>disable fast_start failover;
DGMGRL> show configuration;
Configuration - my_dg_cfg
Protection Mode: MaxAvailability
Databases:
mppay1 - Primary database
mppay2 - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
2.主库暂停归档向备库传输
DGMGRL> show database mppay1
Database - mppay1
Role: PRIMARY
Intended State: TRANSPORT-ON
Instance(s):
MPPAYUAT
Database Status:
SUCCESS
edit configuration set protection mode as MaxPerformance;
edit database 'mppay1' set state='TRANSPORT-OFF';
edit database 'mppay1' set property LogXptMode ='ASYNC';
edit database 'mppay2' set property LogXptMode ='ASYNC';
show database 'mppay1';
#主庫
SQL> show parameter dg_broker;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
dg_broker_config_file1 string /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr1MPPAY1.dat
dg_broker_config_file2 string /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr2MPPAY1.dat
dg_broker_start boolean TRUE
#備機
SQL> show parameter dg_broker;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
dg_broker_config_file1 string /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr1MPPAY2.dat
dg_broker_config_file2 string /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr2MPPAY2.dat
dg_broker_start boolean TRUE
3.备库在新目录下安装新版本软件
3.1 关闭数据库，监听。
[oracle@mppay2 ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/dbhome_1
[oracle@mppay2 ~]$ which sqlplus
/u01/app/oracle/product/11.2.0/dbhome_1/bin/sqlplus
[oracle@mppay2 ~]$ sqlplus / as sysdba
SQL> shutdown immediate;
SQL> exit
[oracle@mppay2 ~]$ lsnrctl stop
3.2 在新目录下安装Oracle 11.2.0.4 软件(only oftware)
--安裝時路徑選擇 新的 ORACLE_HOME
--编辑oracle环境变量，修改ORACLE_HOME为新的目录
vim /home/oracle/.bash_profile
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/dbhome_1
3.3 copy 配置文件
[oracle@oracle2 admin]$ cp /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/*.ora /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/
--修正listener.ora 及 tnsnames.ora 中ORACLE_HOME
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/spfileMPPAYUAT.ora /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr1MPPAY2.dat /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr2MPPAY2.dat /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwMPPAYUAT /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
4.备库启动到mount状态
[oracle@mppay2 ~]$ which lsnrctl
[oracle@mppay2~]$ lsnrctl start
[oracle@mppay2~]$ sqlplus / as sysdba
SQL> startup mount;
5.主库安装软件，升级数据库
5.1 在新目录下安装Oracle 11.2.0.4 软件(only oftware)
--安裝時選擇新的 ORACLE_HOME ,注:监听不需要配置
--编辑oracle用户环境变量，修改ORACLE_HOME新目录
vim .bash_profile
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/dbhome_1
5.2 关闭数据库，监听
[oracle@mppay1 ~]$ lsnrctl stop
[oracle@mppay1 ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/dbhome_1
[oracle@mppay1 ~]$ which sqlplus
/u01/app/oracle/product/11.2.0/dbhome_1/bin/sqlplus
[oracle@mppay1 ~]$ sqlplus / as sysdba
SQL> spool /home/oracle/upgrade01.log
SQL> @/u01/app/oracle/product/11.2.0.4/dbhome_1/rdbms/admin/utlu112i.sql
SQL> spool off
--根据提示修正不符合升级条件的地方,清空回收站
SQL> purge DBA_RECYCLEBIN;
SQL> select count(*) from DBA_RECYCLEBIN;
--查看无效对象
SQL> select count(*) from dba_objects where status<>'VALID';
SQL> EXECUTE dbms_stats.gather_dictionary_stats;
SQL> shutdown immediate
5.3 copy 配置文件
[oracle@oracle2 admin]$ cp /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/*.ora /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/
--修正listener.ora 、 tnsnames.ora 中ORACLE_HOME
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/spfileMPPAYUAT.ora /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr1MPPAY1.dat /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/dr2MPPAY1.dat /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwMPPAYUAT /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/
5.4 升级数据库
[oracle@mppay1 dbs]$ which sqlplus
/u01/app/oracle/product/11.2.0.4/dbhome_1/bin/sqlplus
[oracle@mppay1 dbs]$ sqlplus / as sysdba
SQL> startup UPGRADE
set echo on
spool /home/oracle/update02.log
set time on
SQL>@/u01/app/oracle/product/11.2.0.4/dbhome_1/rdbms/admin/catupgrd.sql
--3o分钟（做完后自動shutdown immediate）
SQL> sqlplus / as sysdba
SQL> startup
SQL> select count(*) from dba_objects where status<>'VALID';
456
SQL> @/u01/app/oracle/product/11.2.0.4/dbhome_1/rdbms/admin/utlrp.sql
SQL> select count(1) from dba_objects where status<>'VALID';
0
SQL> @/u01/app/oracle/product/11.2.0.4/dbhome_1/rdbms/admin/utlu112s.sql
SQL> select count(1) from dba_objects where status<>'VALID';
0
SQL> EXECUTE dbms_stats.gather_dictionary_stats;
SQL> shutdown immediate
SQL> startup
5.5主库启动监听
[oracle@mppay1 ~]$ lsnrctl start
5.6查看oratab
[oracle@mppay1 ~]$ cat /etc/oratab
5.7查看Broker配置
DGMGRL> show configuration

7.检查备库、主库升级情况
SQL>

set pagesize 9999
col comp_name format a40
SQL> SELECT COMP_NAME, VERSION, STATUS FROM SYS.DBA_REGISTRY;

8.修改 compatible 参数(主备)
-- 切记这个参数已修改，此次升级操作就无法回退，一定要在应用经过测试之后修改。
SQL> show parameter compatible
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
compatible string 11.2.0.0.0
SQL> alter system set compatible='11.2.0.4.0' scope=spfile;
- ADG环境DB重启
關閉主機DB
SHUTDOWN IMMEDIATE;
關閉監聽
lsnrctl stop
關閉備機DB
SHUTDOWN IMMEDIATE;
關閉備機監聽
lsnrctl stop
啟動備機監聽
lsnrctl start
啟動備機DB
startup;
啟動主機監聽
lsnrctl start
啟動主機DB
startup;
SQL> show parameter comp;
NAME VALUE
------------------------------------ ---------------------------------
cell_offload_compaction ADAPTIVE
compatible 11.2.0.4.0
nls_comp BINARY
plsql_v2_compatibility FALSE
- 切换到最大可用模式
DGMGRL> edit database 'mppay1' set property LogXptMode ='SYNC';
DGMGRL> edit database 'mppay2' set property LogXptMode ='SYNC';
DGMGRL> edit configuration set protection mode as MaxAvailability;
安装 oracle 11g r2 时出现错误 调用makefile /oracle/app/oracle/product/11.2.0.4/db_1/sysman/lib/ins_emagent.mk的目标nmo时出错。
主要因为C库的问题,解决办法就是手动指定C库位置出现agent nmhs问题后,
找到$ORACLE_HOME/sysman/lib/ins_emagent.mk文件,在文件里找字符串 $(MK_EMAGENT_NMECTL)
替换为$(MK_EMAGENT_NMECTL) -lnnz11
注意：lnnz和$(MK_EMAGENT_NMECTL)之间有空格
然后点“重试“按钮就可以了
修/u01/app/oracle/product/11.2.0/db_1/ctx/lib/ins_ctx.mk，将 ctxhx: $(CTXHXOBJ)
$(LINK_CTXHX)\ (INSO_LINK) 修改为：
ctxhx: $(CTXHXOBJ) -static
$(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) /usr/lib64/stdc.a
点击Retry继续安装。
启动数据库到mount状态出现如下问题，则如下处理
SQL> startup mount;
ORA-00845: MEMORY_TARGET not supported on this system
[root@XAG110 ~]# df -h | grep shm
tmpfs 1.5G 709M 788M 48% /dev/shm
[root@XAG110 ~]# cat /etc/fstab | grep tmpfs
[root@XAG110 ~]# mount -o remount,size=4G /dev/shm
[root@XAG110 ~]# df -h | grep shm
tmpfs 4.0G 709M 3.4G 18% /dev/shm
SQL> startup mount;
Database mounted.
