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。
目 录
一、GI 升级
1) 准备 Linux-zSer 环境 19c 软件,RU19.10 补丁包 p32126842
2) 两节点停集群 备份家目录
3）新建 19c 升级目录
4) 环境变量
5) 图形化升级 GI
6）ORA-59303
7）跑升级脚本完成 GI 安装
8) 挂载磁盘组
9) 最终集群状态如下
二、DB 升级
10）DB 软件安装
11） 数据库实例操作
参数文件创建
附：19c 升级参数文件
12）跑升级脚本 dbupgrade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

# /app/product/11.2.0/grid/bin/crsctl stop crs
# tar -zcvf /app/GI.tar.gz /app/grid /app/oracle /app/product /app/oraInventory3）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

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：

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。

当去改参数时又会报错 ORA-15032:并不是所有的改变都被执行

*
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。

接下来我们对数据磁盘组 DATA 磁盘组也进行如上操作。

当然也可以直接在 CMD 里运行 mount 磁盘组的命令。

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。

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。
