节点	主机版本	主机名	实例名	Oracle版本	IP地址
主库	redhat 7.9	orcl	orcl+cdb19c	11.2.0.4 + 19.3.0（补丁 29585399）	10.211.55.100
备库	redhat 7.9	orcl_stby	不创建实例	19.3.0（补丁 29585399）	10.211.55.101

注意：源库最好冷备拷贝到新机器进行升级，保留源库用于回退。

根据MOS文档 2485457.1可以获取最新版 AutoUpgrade工具下载地址：

二、升级主库

1、用autoUpgrade工具升级主库

参考文章：都2021了，还愁Oracle升级步骤麻烦吗？学会本文，升级如喝水

config文件如下：

cat<<EOF >/soft/conifg.cfg
# Global configurations
global.autoupg_log_dir=/soft/uplogs
global.raise_compatible=yes
global.drop_grp_after_upgrade=yes

# Database number 3 - Noncdb to PDB upgrade
upg3.log_dir=/soft/logs
upg3.sid=orcl
upg3.source_home=/u01/app/oracle/product/11.2.0/db
upg3.target_cdb=cdb19c
upg3.target_home=/u01/app/oracle/product/19.3.0/db
upg3.target_pdb_name=orcl
upg3.target_pdb_copy_option=file_name_convert=('/oradata/orcl/', '/oradata/CDB19C/orcl/')
upg3.start_time=NOW                  # Optional. 10 Minutes from now
upg3.upgrade_node=orcl           # Optional. To find out the name of your node, run the hostname utility. Default is 'localhost'
upg3.run_utlrp=yes              # Optional. Whether or not to run utlrp after upgrade
upg3.timezone_upg=yes           # Optional. Whether or not to run the timezone upgrade
upg3.target_version=19  # Oracle version of the target ORACLE_HOME.  Only required when the target Oracle database version is 12.2
upg3.remove_underscore_parameters=yes
upg3.source_tns_admin_dir=/u01/app/oracle/product/11.2.0/db/network/admin
upg3.target_tns_admin_dir=/u01/app/oracle/product/19.3.0/db/network/admin
EOF

开始升级 non-cdb转换为pdb

至此，主库已升级完成。

检查升级情况：

设置pdb随cdb启动：
alter pluggable database all save state;

在这里插入图片描述

三、搭建ADG

1、主备CDB搭建ADG

备库执行：

dbca -silent -createDuplicateDB \\
-gdbName cdb19c \\
-sid cdb19c \\
-sysPassword oracle \\
-primaryDBConnectionString 10.211.55.100:1521/cdb19c \\
-nodelist orcl_stby \\
-databaseConfigType SINGLE \\
-createAsStandby -dbUniqueName cdb19c_stby \\
-datafileDestination '/oradata'

DBCA创建备库实例 pdb

--主库设置DG参数
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(CDB19C,CDB19C_STBY)';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=/archivelog VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=CDB19C';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=CDB19C_stby ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=CDB19C_STBY';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;
ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=4;
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;
ALTER SYSTEM SET FAL_SERVER=CDB19C_STBY;
ALTER SYSTEM SET FAL_CLIENT=CDB19C;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT='/oradata/CDB19C','/oradata/CDB19C_STBY' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_FILE_NAME_CONVERT='/oradata/CDB19C','/oradata/CDB19C_STBY'  SCOPE=SPFILE;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

--备库设置DG参数
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(CDB19C_STBY,CDB19C)';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=/archivelog VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=CDB19C_STBY';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=CDB19C ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=CDB19C';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;
ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=4;
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;
ALTER SYSTEM SET FAL_SERVER=CDB19C;
ALTER SYSTEM SET FAL_CLIENT=CDB19C_STBY;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT='/oradata/CDB19C_STBY','/oradata/CDB19C' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_FILE_NAME_CONVERT='/oradata/CDB19C_STBY','/oradata/CDB19C'  SCOPE=SPFILE;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

配置ADG参数
2、CDB主备开启同步

##备库执行
alter database recover managed standby database using current logfile disconnect from session;

##主库执行
alter system set log_archive_dest_state_2=enable;

同步情况检查
