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
