大家好，我是 JiekeXu,很高兴又和大家见面了,今天和大家一起来看看 Oracle 11g RAC 原地升级到 19c，欢迎点击上方蓝字“JiekeXu DBA之路”关注我的公众号，标星或置顶，更多干货第一时间到达！

记得去年初的一段时间内，总是在进行数据库 19c 的升级，安装，测试工作，当时不知怎的，有一个特殊的要求就是原地升级 11g RAC 到 19c,刚好操作系统版本以及 JDK 均满足要求，就当学习了，顺便将第一次的测试步骤大概记录了下来，便有了这篇文章。

说明：原环境架构为 Linux-zSer 环境，OS：Suse12sp5  DB:11.2.0.4 RAC

一、GI 升级

1) 准备 Linux-zSer 环境 19c 软件,RU19.10 补丁包 p32126842

drwxrwxrwx  4 grid oinstall       4096 Feb  5 19:52 32126842
-rwxr-xr-x  1 grid oinstall 2835755051 Mar  6 22:02 LINUX.ZSERIES64_193000_db_home.zip
-rwxr-xr-x  1 grid oinstall 2519769777 Mar  6 22:00 LINUX.ZSERIES64_193000_grid_home.zip
drwxr-x--- 15 grid oinstall       4096 Nov  6 03:51 OPatch
-rw-r--r--  1 grid oinstall 2754599824 Mar  6 22:07 p32126842_190000_Linux-zSer_1910_GI_OJVM.zip
-rwxr-xr-x  1 grid oinstall  173937575 Mar  6 22:06 p6880880_122010_Linux-zSer_12.2.0.1.23.zip
-rw-rw-r--  1 grid oinstall     796834 Feb  5 20:21 PatchSearch.xml

2) 两节点停集群 备份家目录

# /app/product/11.2.0/grid/bin/crsctl stop crs
# tar -zcvf /app/GI.tar.gz  /app/grid /app/oracle /app/product /app/oraInventory

3）新建 19c 升级目录

mkdir -p /backup/app/19.0.0.0/grid 
mkdir -p /backup/app/grid 
mkdir -p /backup/app/oracle/product/19.0.0.0/dbhome_1
chown -R grid:oinstall /backup
chown -R oracle:oinstall /backup/app/oracle
chmod -R 775 /backup


--注意：这里新建目录应该按照 oracle 标准目录 OFA 结构建立，但由于不满足，最好建立成如下路径，ORACLE_BASE 不需改动，ORACLE_HOME 如下即可。
mkdir -p /app/product/19.0.0./grid
mkdir -p /app/oracle/product/19.0.0/dbhome_1


官方文档建议如下：
# mkdir -p /u01/app/19.0.0/grid
# mkdir -p /u01/app/grid
# mkdir -p /u01/app/oracle
# mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1
# chown -R grid:oinstall /u01
# chown oracle:oinstall /u01/app/oracle
# chmod -R 775 /u01/

If you create the OFA path /u01, and grant oracle 755 permissions to write to that path, then the Oracle Inventory directory is created in the path /u01/app/oraInventory, and Oracle Universal Installer creates the path /u01/app/oracle, and configures the ORACLE_BASE environment variable for the Oracle user to that path. If you are performing an Oracle Database installation, then the Oracle home is installed under the Oracle base. However, if you are installing Oracle Grid Infrastructure for a cluster, then be aware that ownership of the path for the Grid home is changed to root after installation and the Grid base and Grid home should be in different locations, such as
/u01/app/19.0.0/grid for the Grid home path, and /u01/app/grid for the Grid base. For example:
/u01/app/oraInventory, owned by grid:oinstall
/u01/app/oracle, owned by oracle:oinstall
/u01/app/oracle/product/19.0.0/dbhome_1/, owned by oracle:oinistall
/u01/app/grid, owned by grid:oinstall
/u01/app/19.0.0/grid, owned by root

4) 环境变量

Grid 原有 11g 环境变量

umask 022
export ORACLE_BASE=/app/grid
export ORACLE_HOME=/app/product/11.2.0/grid
export ORACLE_SID=+ASM1
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
export PATH=${ORACLE_HOME}/bin:${ORACLE_HOME}/OPatch:${PATH}
export HOST=`hostname | cut -f1 -d"."`
export PS1='${HOST}:$PWD(${ORACLE_SID})>'

GRID 19c 环境变量：

jieker1:/home/grid(+ASM)>more .bash_profile_19c 
umask 022
export ORACLE_BASE=/backup/app/grid
export ORACLE_HOME=/backup/app/19.0.0.0/grid
export ORACLE_SID=+ASM1
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
export JAVA_HOME=$ORACLE_HOME/jdk
export PATH=$ORACLE_HOME/bin:$PATH:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/jre/bin:$ORACLE_HOME/jdk/bin
export HOST=`hostname | cut -f1 -d"."`
export PS1='${HOST}:$PWD(${ORACLE_SID})>'
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

ORACLE：
原有 11g 环境变量

umask 022
export ORACLE_BASE=/app/oracle
export ORACLE_HOME=/app/product/11.2.0/db
export ORACLE_SID=jiekedb1
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
export LD_LIBRARY_PATH=${ORACLE_HOME}/lib
export PATH=${ORACLE_HOME}/bin:${ORACLE_HOME}/OPatch:${PATH}
export HOST=`hostname | cut -f1 -d"."`
export PS1='${HOST}:$PWD(${ORACLE_SID})>'

Oracle 19c 环境变量

more .bash_profile_19c 


umask 022
export ORACLE_BASE=/backup/app/oracle
export ORACLE_HOME=/backup/app/oracle/product/19.0.0.0/dbhome_1
export ORACLE_SID=jiekedb1
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export PATH=$ORACLE_HOME/bin:$PATH:$ORACLE_HOME/OPatch:.
export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
export HOST=`hostname | cut -f1 -d"."`
export PS1='${HOST}:$PWD(${ORACLE_SID})$'

5) 图形化升级 GI

RAC1  Grid 用户解压 GI 安装软件到 19c 环境变量 $ORACLE_HOME

unzip LINUX.ZSERIES64_193000_grid_home.zip -d $ORACLE_HOME
cd $ORACLE_HOME
--调用图形界面
jieker1:/backup/app/19.0.0.0/grid(+ASM1)>./gridSetup.sh

以升级模式运行 gridSetup.sh

上面的检查关键信息一定要检查通过！！！

6）ORA-59303

在升级 GI 的过程中一定会出现磁盘组兼容性问题而无法正常挂载，就会报如下错误。

ORA-15032: not all alterations performed
ORA-59303: The attribute compatible.asm (11.2.0.0.0) of the diskgroup being mounted should be 11.2.0.2.0 or higher. (DBD ERROR: OCIStmtExecute)

SQL> alter diskgroup ARCH set attribute 'compatible.asm'='11.2.0.4.0';

映像中这里的 OCR 盘我使用的是新划分的 1G 大小的三块盘，新的 OCR 磁盘组为JIEKER_OCR。

7）跑升级脚本完成 GI 安装

跑升级脚本 rootupgrade.sh

rootupgrade.sh 脚本简要信息示例如下：

2021/04/08 16:03:28 CLSRSC-594: Executing installation step 10 of 19: 'ConfigCHMOS'.

2021/04/08 16:06:32 CLSRSC-325: Configure Oracle Grid Infrastructure for a Cluster ... succeeded

8) 挂载磁盘组

ASMCMD> lsdg 
State    Type    Rebal  Sector  Logical_Sector  Block       AU  Total_MB  Free_MB  Req_mir_free_MB  Usable_file_MB  Offline_disks  Voting_files  Name
MOUNTED  NORMAL  N        4096            4096   4096  4194304      3072     2204             1024             590              0             Y  JIEKER_OCR/
ASMCMD> 
ASMCMD> mount JIEKE_ARCH
ORA-15032: not all alterations performed
ORA-59303: The attribute compatible.asm (11.2.0.0.0) of the diskgroup being mounted should be 11.2.0.2.0 or higher. (DBD ERROR: OCIStmtExecute)
ASMCMD>

这里挂载归档磁盘组就会报 ORA-59303，那么我们来查看一下磁盘组的兼容性，发现全是 0，我们需要将其设置为最低为 19.0.0.0.0。

           1 JIEKER_OCR              4096 19.0.0.0.0           10.1.0.0.0

当去改参数时又会报错 ORA-15032:并不是所有的改变都被执行

SQL> alter diskgroup JIEKE_ARCH set attribute 'compatible.asm'='19.0.0.0.0';
alter diskgroup JIEKE_ARCH set attribute 'compatible.asm'='19.0.0.0.0'
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15001: diskgroup "JIEKE_ARCH" does not exist or is not mounted

那么，怎么办呢？这里就需要到一个隐含参数 ‘_disk_sector_size_override’，可以设置_disk_sector_size_override 参数为 true，来覆盖扇区的设置，这样就可以强制挂载磁盘组。

           2 JIEKE_ARCH              4096 19.0.0.0.0           10.1.0.0.0

接下来我们对数据磁盘组 DATA 磁盘组也进行如上操作。

SQL> alter diskgroup JIEKE_DATA  mount restricted;
Diskgroup altered.


SQL> alter diskgroup JIEKE_DATA  SET ATTRIBUTE 'compatible.asm'='19.0.0.0.0'; 
Diskgroup altered.


SQL> select GROUP_NUMBER,NAME,BLOCK_SIZE,COMPATIBILITY,DATABASE_COMPATIBILITY from v$asm_diskgroup;


GROUP_NUMBER NAME             BLOCK_SIZE COMPATIBILITY        DATABASE_COMPATIBI
------------ ---------------- ---------- -------------------- ------------------
           0 JIEKE_OCR                  0 0.0.0.0.0            0.0.0.0.0
           1 JIEKER_OCR              4096 19.0.0.0.0           10.1.0.0.0
           2 JIEKE_ARCH              4096 19.0.0.0.0           10.1.0.0.0
           3 JIEKE_DATA              4096 19.0.0.0.0           10.1.0.0.0


SQL> ALTER diskgroup JIEKE_ARCH dismount;
Diskgroup altered.


SQL> ALTER diskgroup JIEKE_DATA dismount;
Diskgroup altered.

当然也可以直接在 CMD 里运行 mount 磁盘组的命令。

注意：JIEKE_OCR 旧的磁盘组不用挂载，新的 OCR 磁盘组为 JIEKER_OCR。

二、DB 升级

10）DB 软件安装

软件安装和正常的 19c DB 软件安装没有区别，只要 JDK 版本合适，操作系统版本合适，正常下一步下一步就好。

调用图形化运行 ./runInstaller

其他步骤截图略。

11） 数据库实例操作

• 参数文件创建

使用原先修改好的 19c 参数文件 pfile_19c_forupdate.ora 启动数据库。

升级完之后数据库已经关闭，可将 pfile 中关于集群的参数注释 #*.cluster_database=true 去掉 #，然后用 pfile 启动去重建 spfile.

vim '/home/oracle/pfile_19c_forupdate.ora'
#*.cluster_database=true

总结

以上大概步骤为去年 4 月份一测试 RAC 升级 19c 时做的测试步骤，主要就是 GI 升级这块以及后面的数据库实例升级，DB 软件直接安装即可，其他的一些小细节这里没有记录，比如打补丁呀，磁盘挂载呀等等均没有涉及。而实际生产环境步骤肯定要比这个详细完善，这里只是抛砖引玉，供大家借鉴。况且，一般生产环境均是先搭建 19c 新环境迁移升级，很少有直接在原环境下进行升级操作。

以上如有错误及不到的地方，还望海涵。如果有不理解的地方及不周到的地方，也希望正在阅读的你可以添加我个人微信添加我个人微信【JiekeXu_DBA】沟通，谢谢！
