oarcle 19c ADG补丁升级(19.3-19.22)

本文主要是介绍oarcle 19c ADG补丁升级(19.3-19.22)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、备库操作

1.关闭备库数据库实例

sqlplus / as sysdba
startup
shutdown immediate 
# 查看oracle进程
ps -ef | grep sqlplus

2.关闭监听

lsnrctl start 
lsnrctl stop
lsnrctl status

3.升级Opatch

# 备份当前Opatch目录
su - oracle
cd $ORACLE_HOME
mv OPatch OPatch14.bak

4.解压6880880_190000_Linux-x86-64.zip

 cd /softls
unzip -d $ORACLE_HOME p6880880_190000_Linux-x86-64.zip
# 解压完查看OPatch版本
cd $ORACLE_HOME/OPatch
./opatch version

5.解压和应用33806152补丁

cd /soft
ls
unzip p35943157_190000_Linux-x86-64.zip
su - root
cd /soft
chown oracle:oinstall p35943157_190000_Linux-x86-64.zip

6.检查补丁是否冲突

cd 35943157
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail

7.应用补丁

$ORACLE_HOME/OPatch/opatch apply

查看是否应用成功

cd $ORACLE_HOME/OPatch
./opatch lspatches

二、主库操作

1.备份oracle文件

cd $ORACLE_HOME
cd ..
ls
tar -cvzf db_home.tar.gz db_1/

2.主库关闭数据库及监听程序

sqlplus / as sysdba
shutdown immediate
exit
ps -ef |grep sqlplus
**##关闭监听**
lsnrctl start 
lsnrctl stop
lsnrctl status

3.升级OPatch

##拷贝当前Opatch目录
su - oracle
cd $ORACLE_HOME
mv OPatch OPatch14.bak
# 解压p6880880_190000_Linux-x86-64.zip安装包cd /softls
unzip -d $ORACLE_HOME p6880880_190000_Linux-x86-64.zip# 查看OPatch版本
cd $ORACLE_HOME/OPatch
./opatch version

4.应用补丁

# 解压补丁包
cd /soft
ls
unzip p35943157_190000_Linux-x86-64.zipcd 35943157
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail$ORACLE_HOME/OPatch/opatch apply

cd $ORACLE_HOME/OPatch
./opatch lspatches

5.注册前检查

cd $ORACLE_HOME/OPatchlsnrctl start
sqlplus / as sysdba
startup upgrade[oracle@ora19 OPatch]$ ./datapatch -prereq

6.检查完成注册补丁

./datapatch -verbose

7.编译无效对象

cd $ORACLE_HOME//rdbms/admin$ sqlplus / as sysdbaSQL> @utlrp.sql

8.检查主库补丁注册情况

select VERSION,VERSION_FULL from dba_registry;

9.备库切换主库完成补丁注册

1、主库SQL> select name,open_mode,switchover_status from v$database;NAME OPEN_MODE SWITCHOVER_STATUS
--------- -------------------- --------------------
PROD1 READ WRITE TO STANDBYSQL> alter system switch logfile;System altered.SQL> alter system archive log current;System altered.SQL> alter database commit to switchover to physical standby with session shutdown;Database altered.SQL> shutdown abort
ORACLE instance shut down.
SQL> startup mount

TO PRIMARY2、备库

--------- -------------------- --------------------
PROD1 READ WRITE TO STANDBY3、新备库（原主库）启用实时日志应用SQL> alter database recover managed standby database using current logfile disconnect from session;Database altered.SQL> select name,open_mode,switchover_status from v$database;NAME OPEN_MODE SWITCHOVER_STATUS
--------- -------------------- --------------------
RMANPRI READ ONLY RECOVERY NEEDED4、新主库切换日志SQL> alter system switch logfile;System altered.5、分别查看当前主备库切换后当前日志序列号主库：SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /oracle/archive
Oldest online log sequence 52
Next log sequence to archive 54
Current log sequence 54备库：SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /oracle/archive
Oldest online log sequence 53
Next log sequence to archive 0
Current log sequence 546、查看当前主备库状态主库：SQL> select name,open_mode,switchover_status from v$database;NAME OPEN_MODE SWITCHOVER_STATUS
--------- -------------------- --------------------
RMANPRI READ WRITE TO STANDBY备库：SQL> select name,open_mode,switchover_status from v$database;NAME OPEN_MODE SWITCHOVER_STATUS
--------- -------------------- --------------------
RMANPRI READ ONLY WITH APPLY NOT ALLOWED

三、回退补丁

sqlplus / as sysdba
startup
shutdown immediate 
exit# 关闭监听
lsnrctl start 
lsnrctl stop
lsnrctl status
# 回退补丁
cd $ORACLE_HOME/OPatch
./opatch lspatches
./opatch rollback -id 35943157
