Redhat 7.4 Oracle 11.2.0.4升级到18c non-CDB(手动)

Linux从11.2.0.4升级到18c non-CDB(手动)

对于12c之前的版本，如果要升级到12c，18c版本，那么也只能升级到non-CDB模式无法直接升级到CDB模式。

Redhat 7.4 Oracle 11.2.0.4升级到18c (DBUA方式)：
https://www.cndba.cn/Expect-le/article/3020

安装18c数据库软件

新的Oracle环境变量：

ORACLE_BASE=/u02/app/oracle
ORACLE_HOME= /u02/app/oracle/product/18.1.0/dbhome_1
ORACLE_SID=cndba

2)资源配置：

[root@18c ~]# vim /etc/security/limits.conf
oracle  soft  nproc  2047
oracle  hard  nproc  16384
oracle  soft  nofile  1024
oracle  hard  nofile  65536
oracle  soft  stack  10240
oracle  hard  stack  32768
oracle soft memlock 3145728
oracle hard memlock 3145728

mkdir -p /u02/app/oracle/product/18.1.0/dbhome_1
chown -R oracle:oinstall /u02
chmod -R 775 /u02/

解压18c到新的ORACLE_HOME下

unzip -d /u02/app/oracle/product/18.1.0/dbhome_1 Oracle18.1.0.zip

安装数据库软件
只安装数据库软件

如果是单实例则选择第一个

选择企业版

修改为新的ORACLE_BASE目录

默认

安装前检查，内存不符合要求。18c建议的内存为8G

正在安装

执行root.sh脚本

升级前检查

运行查脚本

脚本可以从MOS(ID 884522.1)中下载，也可以在新的$ORACLE_HOME/rdbms/admin/中找到，直接在源库上运行即可，然后根据检查结果修改即可。

在源库上执行脚本检查

[oracle@cndba software]$ /u02/app/oracle/product/18.1.0/dbhome_1/jdk/bin/java -jar /u02/app/oracle/product  
/18.1.0/dbhome_1/rdbms/admin/preupgrade.jar

  /u01/app/oracle/cfgtoollogs/orcl/preupgrade/preupgrade_fixups.sql  

  /u01/app/oracle/cfgtoollogs/orcl/preupgrade/postupgrade_fixups.sql  
Execute fixup scripts as indicated below: 
Before upgrade log into the database and execute the preupgrade fixups  
@/u01/app/oracle/cfgtoollogs/orcl/preupgrade/preupgrade_fixups.sql  
After the upgrade:  
Log into the database and execute the postupgrade fixups  
@/u01/app/oracle/cfgtoollogs/orcl/preupgrade/postupgrade_fixups.sql  
Preupgrade complete: 2018-07-10T15:01:40

     preupgrade.log里记录的是检查的详细信息，有不满足的对象可以通过查看该文件获取。根据提示：在升级前要执行preupgrade_fixups.sql脚本来修复不符合要求的对象。升级后需要执行postupgrade_fixups.sql脚本来修复。

  INFORMATION ONLY

  ================

  14. Check the Oracle documentation for the identified components for their
      specific upgrade procedure.
      The database upgrade script will not upgrade the following Oracle
      components:  OLAP Catalog,OWB
      The Oracle database upgrade script upgrades most, but not all Oracle
      Database components that may be installed.  Some components that are not
      upgraded may have their own upgrade scripts, or they may be deprecated or
      obsolete.

  ORACLE GENERATED FIXUP SCRIPT
  =============================
  All of the issues in database ORCL
  which are identified above as AFTER UPGRADE "(AUTOFIXUP)" can be resolved by
  executing the following
SQL>@/u01/app/oracle/cfgtoollogs/orcl/preupgrade/postupgrade_fixups.sql

执行修复脚本

会自动修复不满足升级条件的问题，如果有没有修复的问题需要手动去修复。

The fixup scripts have been run and resolved what they can. However,
there are still issues originally identified by the preupgrade that
have not been remedied and are still present in the database.
Depending on the severity of the specific issue, and the nature of
the issue itself, that could mean that your database is not ready
for upgrade.  To resolve the outstanding issues, start by reviewing
the preupgrade_fixups.sql and searching it for the name of
the failed CHECK NAME or Preupgrade Action Number listed above.
There you will find the original corresponding diagnostic message
from the preupgrade which explains in more detail what still needs
to be done.

升级APEX
从18c开始，Oracle不会自动更新APEX组件，需要手动更新。
下载APEX：http://www.oracle.com/technetwork/developer-tools/apex/all-archives-099381.html
要写切换到解压的apex所在的目录下再以sysdba身份登录数据库，执行脚本升级

[oracle@cndba apex]$ pwd

打开数据库

在执行完升级脚本后，会自动将数据库关闭，所以需要手动启动数据库。这个重启过程，Oracle刷新所有缓存，清除缓冲区，并执行其他内务活动。这些动作都是为了保证更新后的数据库的整体性和一致性。

可以看到有两个问题需要手动去修复：time zone版本问题和无效对象。

更新TIMEZONE版本

首先从MOS上下载所需的升级脚本(文档 ID 1585343.1)，从Oracle 11.2开始提供了自动升级的脚本，非常方便。

查看当前版本

SQL> SELECT version FROM v$timezone_file;
   VERSION
---------
       14

解压文件，执行检查脚本

[oracle@cndba DBMS_DST_scriptsV1.9]$ ll
total 68
-rw-r--r-- 1 oracle oinstall  6294 Jan  8  2015 countstarTSTZ.sql
-rw-r--r-- 1 oracle oinstall  7213 Mar 17 18:30 countstatsTSTZ.sql
-rw-r--r-- 1 oracle oinstall 19502 Aug 22  2014 upg_tzv_apply.sql
-rw-r--r-- 1 oracle oinstall 31010 Aug 22  2014 upg_tzv_check.sql

a) 检查当前环境

SQL> @/software/DBMS_DST_scriptsV1.9/upg_tzv_check.sql

INFO: NO actual RDBMS DST update will be done by this script.

b) 更新TIMEZONE版本

这里需要注意，执行该脚本会自动重启数据库两次。如下：

SQL> @/software/DBMS_DST_scriptsV1.9/upg_tzv_apply.sql

INFO: If an ERROR occurs the script will EXIT sqlplus.

INFO: The database RDBMS DST version will be updated to DSTv31 .

收集固定对象的统计信息

固定对象的统计信息能够为Oracle优化器提供必需的信息用来找到更有效的执行计划。

SQL> EXECUTE DBMS_STATS.GATHER_FIXED_OBJECTS_STATS

查看组件是否正常

执行脚本utlu122s.sql验证所有组件是否工作正常。

     可以看到都正常。

查看无效对象

SQL>  select owner,object_type,count(*) from dba_objects where status='INVALID' group by owner,object_type order by owner,object_type;

OWNER          OBJECT_TYPE          COUNT(*)

--------------------- ----------------------------------- -------------------

APEX_050100          PACKAGE BODY        2

SCOTT                FUNCTION            1

2 rows selected.

修改COMPATITLE参数

在所有测试完成后且结果都正常，那么就可以将COMPATITLE参数设置为18.1.0。该操作需要重启才能生效。再次打开数据库过程中Oracle会做一个“名称转换”操作，该操作需要几分钟时间。

查看COMPATITLE

SQL> show parameter compatible

NAME                   TYPE        VALUE

------------------------------------ ----------- ------------------------------

compatible               string      11.2.0.0.0

noncdb_compatible        boolean     FALSE

修改COMPATITLE

SQL> alter system set compatible='18.0.0' scope=spfile;

System altered.

重启之前要删除所有的还原点

SQL> col name for a30

SQL> select scn,GUARANTEE_FLASHBACK_DATABASE,NAME from v$restore_point;

SCN    GUA     NAME

------------ ---------  ------------------------------

1493536  YES    GRP_1531210432335

1 row selected.


SQL> drop restore point GRP_1531210432335;

Restore point dropped.

重启数据库

SQL> shutdown immediate

SQL> startup

再次查看COMPATITLE

COMPATITLE参数一旦修改了，就无法降级数据库到原来的版本了。

SQL> show parameter compatible

NAME                   TYPE        VALUE

------------------------------------ ----------- ------------------------------

compatible               string      18.0.0

noncdb_compatible        boolean     FALSE

注：当Oracle Database COMPATIBLE参数更新到18.0.0时，对数据库的第一次Java调用将启动“名称转换”操作。此操作可能需要几分钟才能完成。在增加兼容性参数之后，第一次对数据库进行Java调用时，应该会出现此延迟。执行名称转换的初始延迟仅在初始Java调用期间发生。
