一：版本检查

二：准备19C安装包

三：创建目录

四：安装Oracle软件

五：升级前检查

六：升级

七：验证

八：问题

环境说明：

OS:Red Hat Enterprise Linux Server release 7.5 (Maipo)

DB:Oracle 18.3.0.0.0 升级到 Oracle 19.3.0.0.0

一：版本检测

Oracle 19c - Complete Checklist for Manual Upgrades to Non-CDB Oracle Database 19c (Doc ID 2539778.1)

二：准备19C安装包

---LINUX.X64_193000_db_home.zip

[root@cjcos package]# pwd

/package

[root@cjcos Oracle_1903_for_Linux]# ll -rth

total 2.9G

-rw-r--r-- 1 oracle oinstall 2.9G Jan 19 10:55 LINUX.X64_190000_db_home.zip

三：创建目录

[root@cjcos yum.repos.d]# mkdir -p /u01/app/oracle19

[root@cjcos yum.repos.d]# chown -R oracle:oinstall /u01/app/oracle19

[root@cjcos yum.repos.d]# chmod -R 775 /u01/app

[root@cjcos yum.repos.d]# su - oracle

[oracle@cjcos ~]$ mkdir -p /u01/app/oracle19/product/19.0.0/dbhome_1

[oracle@cjcos ~]$ cd /u01/app/oracle19/product/19.0.0/dbhome_1

四：安装Oracle软件

[oracle@cjcos dbhome_1]$ pwd

/u01/app/oracle19/product/19.0.0/dbhome_1

[oracle@cjcos dbhome_1]$ unzip -q /package/LINUX.X64_190000_db_home.zip

[root@cjcos ~]# xhost +

access control disabled, clients can connect from any host

[oracle@cjcos dbhome_1]$ cd /package/database/

[oracle@cjcos database]$ ./runInstaller

[root@cjcos ~]# /u01/app/oracle19/product/19.0.0/dbhome_1/root.sh

五：升级前检查

[oracle@cjcos ~]$ /u01/app/oracle19/product/19.0.0/dbhome_1/jdk/bin/java -jar /u01/app/oracle19/product/19.0.0/dbhome_1/rdbms/admin/preupgrade.jar

六：升级

[oracle@cjcos ~]$ cd /u01/app/oracle19/product/19.0.0/dbhome_1/bin/

[oracle@cjcos bin]$ ./dbua

SQL> conn / as sysdba

SQL> EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;

SQL>EXECUTE DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;

SQL> alter session set container=cjcpdb01;

SQL> EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;

SQL>EXECUTE DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;

七：验证

设置环境变量

[oracle@cjcos ~]$ vi .bash_profile

export PATH

#export ORACLE_BASE=/u01/app/oracle

#export ORACLE_BASE=/u01/app/oracle12

#export ORACLE_BASE=/u01/app/oracle18

export ORACLE_BASE=/u01/app/oracle19

#export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1

#export ORACLE_HOME=$ORACLE_BASE/product/12.0.0/dbhome_1

#export ORACLE_HOME=$ORACLE_BASE/product/18.0.0/dbhome_1

export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1

#export ORACLE_SID=cjcdb

export ORACLE_SID=cjcdb01

#export ORACLE_SID=cjcdb02

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

[oracle@cjcos ~]$ source .bash_profile

监听状态

[oracle@cjcos ~]$ lsnrctl status

[oracle@cjcos admin]$ pwd

/u01/app/oracle19/product/19.0.0/dbhome_1/network/admin

[oracle@cjcos admin]$ vim tnsnames.ora
