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/dump SYS 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$ ls camsData20181017.dmp camsData20181017.log impdp_camsData20181017.log oracle@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$ ls channel20181024173831.dmp channel20181024173831.log core20181024173831.dmp core20181024173831.log cwap20181024173831.dmp cwap20181024173831.log oracle@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 -k Filesystem 1024-blocks Used Available Capacity Mounted on rpool/ROOT/solaris 205406208 26547648 100958072 21% / /devices 0 0 0 0% /devices /dev 0 0 0 0% /dev ctfs 0 0 0 0% /system/contract proc 0 0 0 0% /proc mnttab 0 0 0 0% /etc/mnttab swap 11726088 2912 11723176 1% /system/volatile objfs 0 0 0 0% /system/object sharefs 0 0 0 0% /etc/dfs/sharetab fd 0 0 0 0% /dev/fd rpool/ROOT/solaris/var 205406208 415600 100958072 1% /var swap 11725976 2800 11723176 1% /tmp rpool/VARSHARE 205406208 3432 100958072 1% /var/share rpool/export 205406208 304 100958072 1% /export rpool/export/home 205406208 320 100958072 1% /export/home rpool/export/home/grid 205406208 1128 100958072 1% /export/home/grid rpool/export/home/oracle 205406208 592 100958072 1% /export/home/oracle rpool/repo 205406208 20656608 100958072 17% /repo rpool 205406208 384 100958072 1% /rpool rpool/VARSHARE/zones 205406208 288 100958072 1% /system/zones rpool/VARSHARE/pkg 205406208 304 100958072 1% /var/share/pkg rpool/VARSHARE/pkg/repositories 205406208 288 100958072 1% /var/share/pkg/repositories 100.100.100.54:/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 1692 dr-xr-xr-x 2 root root 2 Oct 6 2015 home drwxr-xr-x 2 root root 2 Sep 28 22:47 media drwxr-xr-x 18 root sys 18 Sep 29 06:58 kernel drwxr-xr-x 7 root sys 23 Sep 29 07:01 platform drwxr-xr-x 3 root sys 5 Sep 29 07:01 boot lrwxrwxrwx 1 root root 10 Sep 29 07:01 sbin -> ./usr/sbin lrwxrwxrwx 1 root root 9 Sep 29 07:01 bin -> ./usr/bin drwxr-xr-x 2 root sys 2 Sep 29 07:01 mnt drwxr-xr-x 7 root root 7 Sep 29 07:04 system drwxr-xr-x 3 root sys 3 Sep 29 07:04 export drwxr-xr-x 4 grid oinstall 7 Sep 30 01:49 soft drwxr-xr-x 2 root root 2 Oct 2 01:36 iso drwxr-xr-x 3 root root 15 Oct 2 01:41 repo drwxr-xr-x 12 root bin 335 Oct 2 01:54 lib drwxr-xr-x 43 root sys 50 Oct 2 02:22 var drwxr-xr-x 4 root root 4 Oct 2 21:02 rpool drwxr-xr-x 3 root oinstall 3 Oct 2 21:07 u01 drwx------ 21 root root 30 Oct 2 23:34 root drwxr-xr-x 35 root sys 47 Oct 3 00:12 usr drwxr-xr-x 2 grid asmadmin 7 Oct 3 04:52 sharedisk drwxr-xr-x 7 root sys 7 Oct 3 07:31 opt drwxr-xr-x 4 root sys 8 Oct 24 01:13 devices drwxr-xr-x 193 root sys 193 Oct 24 01:13 dev dr-xr-xr-x 1 root root 1 Oct 24 01:14 net dr-xr-xr-x 1 root root 1 Oct 24 01:14 nfs4 drwxrwxrwx 2 nobody nobody 4096 Oct 25 14:36 backup drwxr-xr-x 98 root sys 194 Oct 25 16:40 etc drwxrwxrwt 10 root sys 862 Oct 25 16:46 tmp dr-xr-xr-x 192 root root 480032 Oct 25 16:47 proc
5.测试新directory备份权限
oracle@cwgsdb1:/backup$ expdp directory=dir_dp schemas=hr dumpfile=hr.dmp logfile=hr.log parallel=2 CLUSTER=N Export: Release 11.2.0.4.0 - Production on Thu Oct 25 17:18:54 2018 copyright (c) 1982, 2011, Oracle and/or its affiliates.

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
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
scp camsData20181025.tar.gz oracle@100.100.100.215:/u01/app/oracle/dump
$ lsnrctl stop $ sqlplus / as sysdba sql> shutdown immediate;
（5）关闭定时任务，在任务之前加#
crontab -e
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
oracle@cwgsdb1:~$ srvctl stop database -d cams oracle@cwgsdb1:~$ srvctl start database -d cams -o mount oracle@cwgsdb1:~$ sqlplus / as sysdba sql*Plus: Release 11.2.0.4.0 Production on Thu Oct 25 20:13:32 2018 copyright (c) 1982, 2013, Oracle.

12.还原最新生产数据
（1）解压最新生产数据
oracle@cwgsdb1:~$ cd oracle@cwgsdb1:~$ cd /u01/app/oracle/dump/ oracle@cwgsdb1:/u01/app/oracle/dump$ ls camsData20181025.tar.gz oracle@cwgsdb1:/u01/app/oracle/dump$ tar zxvf camsData20181025.tar.gz x camsData20181025.dmp, 7310499840 bytes, 14278320 tape blocks x 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 cams oracle@cwgsdb1:/u01/app/oracle/dump$ srvctl start database -d cams -o mount oracle@cwgsdb1:/u01/app/oracle/dump$ sqlplus / as sysdba sql*Plus: Release 11.2.0.4.0 Production on Thu Oct 25 20:52:54 2018 copyright (c) 1982, 2013, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP, Data Mining and Real Application Testing options sql> alter database archivelog; Database altered. sql> alter database open; Database altered. sql> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination +DATADG Oldest online log sequence 4 Next log sequence to archive 7 Current log sequence 7 另一个节点也执行： sql> alter database open; Database altered. sql> select open_mode from gv$database; OPEN_MODE -------------------- READ WRITE READ WRITE
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
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！这里是编程之家网站，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！
