1.清理RAC集群中测试数据

（1）关闭应用服务器所有应用

（2）删除数据库中所有用户数据

DROP USER "XXXX" CASCADE;

2.清理RAC集群中RMAN备份文件

3.清理RAC集群中逻辑备份文件

（1）查看所有在用directories

SQL> set lines 300;SQL> col OWNER for a30;SQL> col DIRECTORY_NAME for a30;SQL> col DIRECTORY_PATH for a50;SQL> select * from dba_directories where DIRECTORY_NAME in ('DIR_DP','DPDATA1');OWNER                          DIRECTORY_NAME                 DIRECTORY_PATH------------------------------ ------------------------------ --------------------------------------------------SYS                            DPDATA1                        /u01/app/oracle/dumpSYS                            DIR_DP                         /u01/app/oracle/admin/cams/dpdump/

（2）清理directories路径下文件

oracle@cwgsdb1:~$ cd /u01/app/oracle/dumporacle@cwgsdb1:/u01/app/oracle/dump$ lscamsData20181017.dmp        camsData20181017.log        impdp_camsData20181017.logoracle@cwgsdb1:/u01/app/oracle/dump$ rm *oracle@cwgsdb1:/u01/app/oracle/dump$ cd /u01/app/oracle/admin/cams/dpdump/oracle@cwgsdb1:/u01/app/oracle/admin/cams/dpdump$ lschannel20181024173831.dmp  channel20181024173831.log  core20181024173831.dmp     core20181024173831.log     cwap20181024173831.dmp     cwap20181024173831.logoracle@cwgsdb1:/u01/app/oracle/admin/cams/dpdump$ rm *oracle@cwgsdb1:/u01/app/oracle/admin/cams/dpdump$ ls

4.在第RAC第一个节点调整directory路径，指向NFS文件系统

（1）该服务器挂载NFS，查看NFS信息：

oracle@cwgsdb1:~$ df -kFilesystem           1024-blocks        Used   Available Capacity  Mounted onrpool/ROOT/solaris     205406208    26547648   100958072    21%    //devices                       0           0           0     0%    /devices/dev                           0           0           0     0%    /devctfs                           0           0           0     0%    /system/contractproc                           0           0           0     0%    /procmnttab                         0           0           0     0%    /etc/mnttabswap                    11726088        2912    11723176     1%    /system/volatileobjfs                          0           0           0     0%    /system/objectsharefs                        0           0           0     0%    /etc/dfs/sharetabfd                             0           0           0     0%    /dev/fdrpool/ROOT/solaris/var                       205406208      415600   100958072     1%    /varswap                    11725976        2800    11723176     1%    /tmprpool/VARSHARE         205406208        3432   100958072     1%    /var/sharerpool/export           205406208         304   100958072     1%    /exportrpool/export/home      205406208         320   100958072     1%    /export/homerpool/export/home/grid                       205406208        1128   100958072     1%    /export/home/gridrpool/export/home/oracle                       205406208         592   100958072     1%    /export/home/oraclerpool/repo             205406208    20656608   100958072    17%    /reporpool                  205406208         384   100958072     1%    /rpoolrpool/VARSHARE/zones   205406208         288   100958072     1%    /system/zonesrpool/VARSHARE/pkg     205406208         304   100958072     1%    /var/share/pkgrpool/VARSHARE/pkg/repositories                       205406208         288   100958072     1%    /var/share/pkg/repositories100.100.100.54:/impbackup                        51606140    15116928    33867772    31%    /backup

（2）调整directory路径：

create or replace directory dir_dp as '/backup/';grant read,write on directory dir_dp to public;

（3）查看NFS文件权限：

oracle@cwgsdb1:~$ ls -lrt /total 1692dr-xr-xr-x   2 root     root           2 Oct  6  2015 homedrwxr-xr-x   2 root     root           2 Sep 28 22:47 mediadrwxr-xr-x  18 root     sys           18 Sep 29 06:58 kerneldrwxr-xr-x   7 root     sys           23 Sep 29 07:01 platformdrwxr-xr-x   3 root     sys            5 Sep 29 07:01 bootlrwxrwxrwx   1 root     root          10 Sep 29 07:01 sbin -> ./usr/sbinlrwxrwxrwx   1 root     root           9 Sep 29 07:01 bin -> ./usr/bindrwxr-xr-x   2 root     sys            2 Sep 29 07:01 mntdrwxr-xr-x   7 root     root           7 Sep 29 07:04 systemdrwxr-xr-x   3 root     sys            3 Sep 29 07:04 exportdrwxr-xr-x   4 grid     oinstall       7 Sep 30 01:49 softdrwxr-xr-x   2 root     root           2 Oct  2 01:36 isodrwxr-xr-x   3 root     root          15 Oct  2 01:41 repodrwxr-xr-x  12 root     bin          335 Oct  2 01:54 libdrwxr-xr-x  43 root     sys           50 Oct  2 02:22 vardrwxr-xr-x   4 root     root           4 Oct  2 21:02 rpooldrwxr-xr-x   3 root     oinstall       3 Oct  2 21:07 u01drwx------  21 root     root          30 Oct  2 23:34 rootdrwxr-xr-x  35 root     sys           47 Oct  3 00:12 usrdrwxr-xr-x   2 grid     asmadmin       7 Oct  3 04:52 sharediskdrwxr-xr-x   7 root     sys            7 Oct  3 07:31 optdrwxr-xr-x   4 root     sys            8 Oct 24 01:13 devicesdrwxr-xr-x 193 root     sys          193 Oct 24 01:13 devdr-xr-xr-x   1 root     root           1 Oct 24 01:14 netdr-xr-xr-x   1 root     root           1 Oct 24 01:14 nfs4drwxrwxrwx   2 nobody   nobody      4096 Oct 25 14:36 backupdrwxr-xr-x  98 root     sys          194 Oct 25 16:40 etcdrwxrwxrwt  10 root     sys          862 Oct 25 16:46 tmpdr-xr-xr-x 192 root     root      480032 Oct 25 16:47 proc

5.测试新directory备份权限

6.原生产环境日结关门

在业务人员完成当日业务后，机构关门，防止业务人员登录系统做业务。计划在数据库迁移完成之后执行日结跑批。

7.原生产环境关闭电票前置机应用

登陆电票前置机weblogic控制台，使用tail -f命令查看当前是否在刷日志，如果没有刷日志，则通过控制台关闭电票前置机应用。

8.原生产环境关闭应用

按照应用关闭的逻辑顺序，依次关闭原生产环境应用。

9.原生产环境数据库备份后下线

（1）原数据库备份命令

expdp \'/ as sysdba\' DIRECTORY=dpdata1 DUMPFILE=camsData20181025.dmp SCHEMAS=xxxx,yyyy logfile=camsData20181025.log

（2）文件压缩

tar zcvf camsData20181025.tar.gz camsData20181025.dmp camsData20181025.log

（3）将文件传输至新生产数据库服务器第一个节点中

scp camsData20181025.tar.gz oracle@100.100.100.215:/u01/app/oracle/dump

（4）关闭老生产数据库

$ lsnrctl stop$ sqlplus / as sysdbaSQL> shutdown immediate;

（5）关闭定时任务，在任务之前加#

crontab -e

（6）修改旧数据库服务器IP地址为其他地址。

10.修改RAC集群的scan ip为生产数据库IP

按照测试环境验证过的流程，修改RAC集群的scan ip为生产数据库IP。

11.关闭生产环境归档

12.还原最新生产数据

（1）解压最新生产数据

oracle@cwgsdb1:~$ cdoracle@cwgsdb1:~$ cd /u01/app/oracle/dump/oracle@cwgsdb1:/u01/app/oracle/dump$ lscamsData20181025.tar.gzoracle@cwgsdb1:/u01/app/oracle/dump$ tar zxvf camsData20181025.tar.gzx camsData20181025.dmp, 7310499840 bytes, 14278320 tape blocksx camsData20181025.log, 345007 bytes, 674 tape blocks

（2）执行导入命令

impdp \'/ as sysdba\' DIRECTORY=dpdata1 DUMPFILE=camsData20181025.dmp SCHEMAS=xxxx,yyyy logfile=impdp_camsData20181025.log cluster=N

13.删除导入时提示的无效对象

（注：这里需要和开发人员确认，确认后删除）

drop FUNCTION "DATABUFF"."ELEMIDX";drop FUNCTION "DB2ODESK"."FSBN";drop PROCEDURE "DB2ODESK"."BATCH_DELETE";drop PROCEDURE "DB2ODESK"."SP_DESK_CURRZS";drop PACKAGE BODY "DATABUFF"."MIGRATION_TRANSFORMER";drop FUNCTION "CAMS_BCE"."TX_ZD2";drop FUNCTION "CAMS_BCE"."TX_ZD3";

14.开启生产环境归档

oracle@cwgsdb1:/u01/app/oracle/dump$ srvctl stop database -d camsoracle@cwgsdb1:/u01/app/oracle/dump$ srvctl start database -d cams -o mountoracle@cwgsdb1:/u01/app/oracle/dump$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.4.0 Production on Thu Oct 25 20:52:54 2018Copyright (c) 1982, 2013, Oracle.

15.部署生产环境RMAN策略，并执行全量备份

按照测试环境验证过的流程，部署生产环境RAMN策略，并执行手工全量备份。

16.手工收集统计信息

exec dbms_stats.gather_schema_stats('XXXX');

17.修改生产应用中数据库连接为service连接

按照测试环境验证过的流程，修改生产应用中数据库连接为service连接

18.启动生产环境应用并验证

（注：生产系统使用查询交易进行验证）

按顺序依次启动应用，测试多组跨子系统的查询交易，然后在数据总线监控平台上查看交易的报文以及成功状态。

19.验证批量功能

（注：如果遇到问题，需第一时间处理）

生产环境执行跑批操作，将会计日期跑到第二日，同时验证功能是否正常。

20.生产环境数据库查询用户设定

（这里选择现有用户scott作为插叙用户，只赋予查询权限）

由于测试阶段已经将scott用户解锁，这里不再重复操作。

select 'grant select on XXXX.' || OBJECT_NAME || ' to scott;'  from DBA_OBJECTS where owner='XXXX' and object_type in ('TABLE','VIEW');

执行上述语句生成的SQL，可为scott用户赋予查询所有业务表和视图的权限。

21.开启电票前置机

登陆电票前置机weblogic控制台，通过控制台开启电票前置机应用。

22.其他问题处理

（1）由于迁移时遇到ORA-04063: view "CAMS_CWAP.QUERYSHOUXIN_V" 有错误的问题，为保证数据表、视图权限完整性，单独执行报表权限脚本。

（2）Linux和Unix系统中date命令不一样，迁移后需单独调整。

（3）Linux和Unix系统中nc命令不一样，迁移后需单独调整。

（4）测试过程发现新生产数据库与测试环境未进行网络隔离，存在一定风险。已通知网络工程师处理。

23.隔日检查RMAN备份集，确认生产运行情况

经过确认，RMAN已经按照既定策略执行备份和历史文件删除，生产环境运行稳定。

至此，生产环境切换工作全部完成完毕，生产环境Oracle数据库成功从Linux X86单机迁移到Solaries双节点RAC集群。

到此，相信大家对"Oracle数据库怎么从Linux x86单机迁移到Solaries双节点RAC集群"有了更深的了解，不妨来实际操作一番吧！这里是网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
