”由于MySQL已经是一个运行了众多知名Web2.0网站的数据，包括Craigslist、Digg、Wikipedia和Google等，或许我们可以说每一个Web2.0公司实质上是一个使用MySQL数据库的公司。oracle|数据|数据库
公司比来要上shopfloor体系,需将数据库从东莞转移过去,以下就是转移的经由…

东莞体系情况:

OS:Windows2000AdvancedServer+SP4

Oracle9istandardEditionVersion:9.0.1.1.1

吴江体系情况:

HPML570CPU:IntelXeonMPCPU3.0GRAM:2GB

OS:Windows2000AdvancedServer+SP4

Oracle9iStandardEditonVersion:9.2.0.1.0.

步骤:

1.安装Oracle9i,选择只安装Software,不创立数据库,安装历程略.

2.创立相干目次:d:oracleadminwjsfmsdump

d:oracleadminwjsfmscdump

d:oracleadminwjsfmsudump

d:oracleadminwjsfmscreate

d:oracleadminwjsfmspfile

3.Copy数据文件到E:OradataWJSFMS目次下,一时文件可不COPY,文件清单以下:

SYSTEM01.DBFNDOTBS01.DBFCWMLITE01.DBFDRSYS01.DBFEXAMPLE01.DBFINDX01.DBFTOOLS01.DBF
USERS01.DBFCSFIS01.ORASFIS01.ORARSFIS02.ORAHSFIS01.ORACINDX01.ORARINDX01.ORA
RINDX02.ORAHINDX01.ORAUNDOTBS2.ORA

4.COPY把持文件G:ControlFileWJSFMS,H:ControlFileWJSFMS,I:ControlFileWJSFMS

5.COPYRedo文件到G:RedoLogWJSFMS,H:RedoLogWJSFMS,I:RedoLogWJSFMS

6.新建实例,此SID必需跟本来的SID一样…

C:Oradim–NEW–SIDWJSFMS–STARTMODEm

7.创立暗码文件

C:orapwdfile=d:oracleora92databasepwdwjsfms.orapassword=passwordentries=5

8.修正初始参数文件INITwjsfms.ora,如没有参数文件,则可用oracle自带的参数文件举行修正,白色部分为修正部分:

…….

control_files=("G:ControlFileWJSFMSCONTROL01.CTL","H:ControlFileWJSFMSCONTROL02.CTL","I:ControlFileWJSFMSCONTROL03.CTL")

……………………..

background_dump_dest=d:oracleadminWJSFMSdump

core_dump_dest=d:oracleadminWJSFMScdump

timed_statistics=TRUE

user_dump_dest=d:oracleadminWJSFMSudump

……………………….

log_archive_dest=f:oraclewjsfmsarchivelog



假如是依据oracle自带的参数文件举行修正的,则还需修正db_name,instance_name

9.激活oracle

c:qlplus/nolog

sql>conn/assysdba

sql>startuppfile=d:oracleora92databaseinitwjsfms.ora

此时提醒以下信息(因为晋级时未将相干信息spool出来,故只能将alert文件中的信息show出来作为参考):

ORA-00218:blocksize4096ofcontrolfiledoesnotmatchDB_BLOCK_SIZE(8192)

ORA-00202:controlfile:G:ControlFileWJSFMSCONTROL01.CTL

呈现此毛病的缘故原由是本来的database的db_block_size跟如今的初始化参数设的纷歧样,将初始化参数中的db_block_size=8192改成4096便可

sql>shutdownimmediate

sql>startuppfile=d:oracleora92databaseinitwjsfms.ora

ORA-01157:cannotidentify/lockdatafile1-seeDBWRtracefile

ORA-01110:datafile1:D:ORACLEORADATAWJSFMSYSTEM01.DBF

ORA-27041:unabletoopenfile

sql>alterdatabaseopen;

alterdatabaseopen

*

ERRORatline1:

ORA-00313:openfailedformembersofloggroup1ofthread1

ORA-00312:onlinelog1thread1:E:ORACLEORADATAISCO12REDO01.LOG



再次实行alterdatabaserenamefile

sql>alterdatabaserenamefileD:ORACLEORADATAWJSFMSREDO01.LOGtoG:RedoLogWJSFMSREDO01.LOG;

alterdatabaserenamefileD:ORACLEORADATAWJSFMSREDO02.LOGtoH:RedoLogWJSFMSREDO02.LOG;

alterdatabaserenamefileD:ORACLEORADATAWJSFMSREDO03.LOGtoI:RedoLogWJSFMSREDO03.LOG;



此时实行alterdatabaseopen

sql>alterdatabaseopen;

此时提醒:

Errorsinfiled:oracleadminwjsfmsudumpwjsfms_ora_2516.trc:

ORA-10827:databasemustbeopenedwithMIGRATEoption

然后instance主动shutdown

呈现这个缘故原由是因为数据库版本纷歧致酿成的,本来版本是9.0.1.1.1,如今是9.2.0.1.0.

10.数据库晋级:

检察oracleonlinedocument,决意手工晋级数据库

sql>startupmigratepfile=d:oracleora92databaseinitwjsfms.ora

SQL>SPOOLupgrade.log

至此数据库转移终了
DBaaS系统其实具有更大的市场机遇：像其他云服务一样，DBaaS意味着更短的销售周期，更少的启动费用，持续不断的收入，也意味着比之前更多的客户。

只能告诉你，学好数据库语言和原理，多见识几种数据库软件，比一棵树上吊死要好。

是否碎片会引发效率问题？这都是需要进一步探讨的东西。varbinary(max)代替image也让SQLServer的字段类型更加简洁统一。

其中最有名的应该是row_number了。这个终于解决了用临时表生成序列号的历史，而且SQLServer2005的row_number比Oracle的更先进。因为它把Orderby集成到了一起，不用像Oracle那样还要用子查询进行封装。

索引视k就有。但是2005对其效率作了一些改进但是schema.viewname的作用域真是太限制了它的应用面。还有一大堆的环境参数和种种限制都让人对它有点却步。
