11g数据库使用DBUA升级Exadata数据库至12c
DB Name: GRP
Source DB: 11.2.0.3
Target DB: 12.1.0.2
11g数据库使用DBUA升级Exadata数据库至12c前提条件:
0.需要11g源数据库full + archivelog backup 备份 本例中备份集放在以下目录。
[oracle@dm08db01 backup]$ pwd
/home/oracle/lyon/backup
备份脚本:backup_grp.txt
run {
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup AS COMPRESSED BACKUPSET incremental level 0 format '/u01/app/oracle/backup/inc0_%d_%U_%Y%M%D.bak' tag hot_db_bk_level0 database;
release channel c1;
release channel c2;
release channel c3;
sql 'alter system archive log current';
allocate channel c1 type disk;
allocate channel c2 type disk;
backup AS COMPRESSED BACKUPSET format '/u01/app/oracle/backup/arc0_%d_%U_%Y%M%D.bak' archivelog all not backed up 1 times;
release channel c1;
release channel c2;
backup current controlfile format '/u01/app/oracle/backup/ctl_%d_%U_%Y%M%D.bak';
}
1. 源端11g/目标端12c 的Oracle Home需要提前安装且打好所需补丁.
2. 11g OH需要追加打Patch#21150904 确保源端数据库可以注册到12C的CRS.
(Bug 13460353 - Registration of 11.2 database fails against 12.1 CRS stack (required fix for 11g DB with 12c GI))
3. 目标端ASM磁盘组兼容性问题. 需要将12C ASM磁盘组Database compatibility降级至11.2.0.0.0
4. 源端11g OH需要relink rds_ipc
cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk ipc_rds ioracle
5. 源端初始化参数需要设置cluster_interconnects
GRP1.cluster_interconnects=192.168.18.1,192.168.18.2
GRP2.cluster_interconnects=192.168.18.3,192.168.18.4
6. 升级过程一定要注意环境变量的设置
GRP_11G_env 为11g Oracle Home 环境变量
GRP_env 为12C Oracle Home 环境变量
下面开始升级过程.
Upgrade 11g Oracle database GRP to 12C.
0. Edit source database pfile and create target pfile&spfile&passwordFile.
0.1 Edit source pfile esp. init parameters like cluster_database/local_listener/remote_listener.

0.4 shutdown the DB and nomount it.
[oracle@dm08db01 dbs]$ . GRP_11G_env
shutdown immediate;

show parameter spfile;
1. restore target controlfile
rman target /
restore controlfile from '/home/oracle/lyon/backup/ctl_GRP_tfru5il9_1_1_20170302.bak';
2. mount DB.
SQL> alter database mount;
Database altered.
SQL>
3. catalog backup files.
RMAN> catalog start with '/home/oracle/lyon/backup';
list backup set.
RMAN> list backup of database completed after 'sysdate-2';
4. Prepare the restore&recovery script
select 'set newname for datafile '||FILE#||' to '''||replace(NAME,substr(NAME,0,instr(NAME,'/',-1)),'+DATA_DM08/GRP/') ||''';'
from v$datafile;
Edit the script restore_GRP.txt

restore database;
switch datafile all;
recover database;
}
5.
restore&recover DB.
nohup /u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target / cmdfile=/home/oracle/lyon/backup/restore_GRP.txt &
monitoring:
[oracle@dm08db01 backup]$ tail -f nohup.out
6. rename logfile.
select 'alter database rename file '||''''||member||''''||' to '||''''||replace(member,substr(member,0,instr(member,'/',-1)),'+DATA_DM08/GRP/') ||''';'
from v$logfile order by GROUP#;
alter database rename file '+DATA_DM04/grpstdby/log_g11m1.dbf' to '+DATA_DM08/GRP/log_g11m1.dbf';
alter database rename file '+DATA_DM04/grpstdby/log_g12m1.dbf' to '+DATA_DM08/GRP/log_g12m1.dbf';
alter database rename file '+DATA_DM04/grpstdby/log_g13m1.dbf' to '+DATA_DM08/GRP/log_g13m1.dbf';
alter database rename file '+DATA_DM04/grpstdby/log_g14m1.dbf' to '+DATA_DM08/GRP/log_g14m1.dbf';
alter database rename file '+DATA_DM04/grpstdby/onlinelog/group_5.588.929287435' to '+DATA_DM08/GRP/group_5.588.929287435';
alter database rename file '+DATA_DM04/grpstdby/onlinelog/group_6.587.929287435' to '+DATA_DM08/GRP/group_6.587.929287435';

7. open upgrade resetlogs the database.
alter database open resetlogs upgrade;
8. CRS registration to 12C CRS.
srvctl add database -d GRP -o /u01/app/oracle/product/11.2.0/dbhome_1
srvctl add instance -d GRP -i GRP1 -n dm08db01
srvctl add instance -d GRP -i GRP2 -n dm08db02
srvctl modify database -d GRP -p '+DATA_DM08/GRP/spfilegrp'
srvctl config database -d GRP -a
srvctl modify database -d GRP -a DATA_DM08,DBFS_DG,RECO_DM08
9.Add the DB to /etc/oratab
9.
alter system reset remote_os_authent scope=spfile;
alter system set cluster_database=true scope=spfile;
10. Test a DB restart.
srvctl stop database -d GRP
srvctl start database -d GRP
11. Upgrade the DB using DBUA. 注意这里要使用12c的oracle home.
[oracle@dm08db01 env]$ . GRP_env
[oracle@dm08db01 env]$ export DISPLAY=10.129.61.157:0.0
[oracle@dm08db01 env]$ dbua
