-----------------------------------------
关闭数据库实例及相关进程 (静态监听、动态监听、EOM、相关服务)
-root下
mkdir -p /u02/app/oracle/product/12.2.0/db_1
chown -R oracle:oinstall /u02/app
chmod -R 775 /u02/app
mkdir -p /u02/setup
chown -R oracle:oinstall /u02/setup
chmod -R 775 /u02/setup
yum -y install smartmontools
rpm -Va pdksh-5.2.14-37.el5_8.1.i386
yum -y install ksh
7. 修改环境变量
然后，再修改oracle用户的.bash_profile
ORACLE_BASE=/u02/app/oracle;export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/12.2.0/db_1
然后source ~/.bash_profile
-------开始安装ORACLE 12C软件（選擇 Upgrade an existing database）------------------------------
archive log list;
shutdown immediate;
startup mount;
select status from v$instance;
alter database noarchivelog;
alter database open;
archive log list;
8. 登录查看，升级后版本
[oracle@11g ~]$ sqlplus / as sysdba
set linesize 150;
set pagesize 9999;
col comp_name format a40;
SELECT COMP_NAME, VERSION, STATUS FROM SYS.DBA_REGISTRY;
SQL> select count(*) from dba_objects where status<>'VALID';
COUNT(*)
----------
0
SQL> select * from utl_recomp_errors;
no rows selected
------------------------------------------------------------------------
编译失效对象(如存在失效對象，則運行如下腳本）
SQL>@$ORACLE_HOME/rdbms/admin/catuppst.sql
Session altered.
--多次执行utlrp.sql，失效对象数量不再变化
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
--------------------------------------------------------------------------
col owner for a20;
col object_name for a32;
col object_type for a16;
col status for a8;
select owner, object_name, object_type, status
from dba_objects
where status='INVALID'
order by 1,2,3;
9. 修改compatible参数，若修改完成，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;
SQL> alter system set compatible='12.2.0.1.0' scope=spfile;
SQL>
shutdown immediate;
startup;
show parameter compatible;
SQL>
set linesize 150;
set pagesize 9999;
col comp_name format a40;
SELECT COMP_NAME, VERSION, STATUS FROM SYS.DBA_REGISTRY;
----------------------------------升級完成----------------------------------------------------------------
