基本信息*

测试目的:
检查确认TEST（这里TEST代替数据库名）从WINDOWS迁移到LINUX是否具有可行性。
这里通过手动XTTS的方法进行迁移，由于XTTS的PERL脚本不支持源服务端为WINDOWS，所以这里用手动XTTS（RMAN备份集方式）。
迁移前检查
1.检查平台
SELECT PLATFORM_id,PLATFORM_NAME, ENDIAN_FORMAT
FROM V$TRANSPORTABLE_PLATFORM
WHERE PLATFORM_ID =
( SELECT PLATFORM_ID
FROM V$DATABASE );
2.检查字符集
select * from nls_database_parameters where parameter=‘NLS_CHARACTERSET‘;
3检查时区
select dbtimezone from dual;
4.检查命令进行自包含检查(重点）
exec sys.dbms_tts.transport_set_check(‘TEST_INDEX,TEST1_INDEX,TEST2_DATA,TEST3_DATA,TEST4_DATA,TEST3_INDEX‘,TRUE);

select select * from TRANSPORT_SET_VIOLATIONS;
开始迁移
1.在源端 （进行全备份）
RMAN TARGET /
run{
allocate channel t1 type disk;
backup incremental level=0 tablespace TEST_INDEX,TEST1_INDEX,TEST2_DATA,TEST3_DATA,TEST4_DATA,TEST3_INDEX
format ‘I:\pglng-backup\rman\TESTtbs0_%U‘tag=TESTtbs0;
release channel c1;
}
2.在目的端进行全量恢复
DECLARE
devtype varchar2(256);
done Boolean;
BEGIN
Devtype:=sys.dbms_backup_restore.deviceAllocate(type=>‘‘,ident=>‘t1‘);
sys.dbms_backup_restore.restoreSetDatafile;
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>05,toname=>‘/data/test/test1_INDEX.DBF‘);
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>06,toname=>‘/data/test/test2_INDEX.DBF‘);
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>07,toname=>‘/data/test/test3_DATA.DBF‘);
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>08,toname=>‘/data/test/test1_DATA.DBF‘);
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>09,toname=>‘/data/test/test2_DATA.DBF‘);
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>10,toname=>‘/data/test/test3_INDEX.DBF‘);
sys.dbms_backup_restore.restoreBackupPiece(done=>done,handle=>‘/u01/rman/leve0/testTBS0_0HV7GF2Q_1_1‘,params=>null);
sys.dbms_backup_restore.deviceDeallocate;
END;

第一次增量备份

进行数据库割接

把要迁移表空间设为只读状态
alter tablespace exessa_data readonly;
alter tablespace exessa_index readonly;
alter tablespace appquery_data readonly;
alter tablespace appquery_index readonly;
alter tablespace fullquery_data readonly;
alter tablespace fullquery_index readonly;
最后增量备份（注最后增量备份前必须把表空间置为只读，不然最后导入元数据会报错）

rman target /
run{
backup incremental level=1 tablespace test1_INDEX,test2_INDEX,test2_DATA,test1_DATA,test3_DATA,test3_INDEX
   format ‘I:\pglng-backup\rman\testtbs1_%U‘tag=testtbs1;
}

最后增量恢复

outhandle varchar2(512);
outtag varchar2(30);
done boolean;
failover boolean;
devtype varchar2(256);
BEGIN
DBMS_OUTPUT.put_line(‘Entering Rollforward‘);

把元数据导入目标库

imp "‘sys/admin2295 as sysdba‘" transport_tablespace=y TABLESPACES=‘test1_INDEX‘,‘test1_DATA‘,‘test2_DATA‘,‘test2_INDEX‘,‘test3_INDEX‘,‘test3_DATA‘ FILE=/u01/exp/testtablespace.dmp log=/u01/exp/testtablespace.log datafiles=‘/data/test/test2_DATA.DBF‘,‘/data/test/test2_INDEX.DBF‘,‘/data/test/test3_INDEX.DBF‘,‘/data/test/test3_DATA.DBF‘,‘/data/test/test1_DATA.DBF‘,‘/data/test/test1_INDEX.DBF‘
