发现log事务日志文件很大，数据文件2G左右，日志超过15G，决定压缩。
使用以下命令：

–截断事务
BACKUP LOG with no_log
use Heihe
DBCC SHRINKFILE (heihe_log)
将之收缩到默认大小

1. 新安装sql server 2k+sp4，建named instance，注意位置与被恢复前的位置一致，同样的盘符
2. 打开企业管理器，新建sde, westdc, dnnWestdc三个新库，关闭企业管理器
3. 打开sql 查询分析器，执行
restore database westdc from disk = ‘E:SQL_BACKUPwestdcwestdc_db_200609140200.BAK’
…
3.1 注意 sde生成时的命名方式是 sde_dat (instead of sde_Data generated by sql svr 2k by default) -> sde.mdf (instead of sde_Data.mdf by default), and sde_Log (same as default) -> sdelog.ldf (instead of sde_Log.ldf by default)，所以需要在生成sde时注意修改对应的名字
4. 恢复 model, msdb, pubs三个数据库
restore database model from disk = ‘E:SQL_BACKUPmodelmodel_db_200609210200.BAK’
restore database msdb from disk = ‘e:sql_backupmsdbmsdb_db_200609210200.BAK’
restore database pubs from disk = ‘e:sql_backuppubspubs_db_200609210200.BAK’

5. 恢复master，必须在单用户模式下进行
5.1 停止现有的sql server 服务
5.2 open command window, come to the named instance directory, for example, E:WESTDC-sqldbMSSQL$WESTDCBinn
5.2. run sqlservr -c -m -s WESTDC. WESTDC is the name of instance going to run
5.3 打开sql查询分析器，运行 restore database master from disk = ‘e:sql_backupmastermaster_db_200609210200.BAK’
结果提示：
已成功地还原了 master 数据库。正在关闭 SQL Server。
SQL Server 正在终止此进程。
DONE!

注，如果位置不一致，可以通过detach和attach函数移动数据库（包括用户数据库和pubs, model, msdb, tempdb, master）到新位置，具体操作见微软支持：http://support.microsoft.com/kb/224071/

将以下内容保存为 OracleExportAutomata.bat，运行即可。可以与Windows计划任务联合使用，比如每天3:00am运行一次。

REM This program is used to export data in Oracle to external files named with current date.
REM A simple export schema is employed. Monday the data will be completely exported.
REM Tuesday through Thursday data will be exported in an incremental manner.
REM Friday, data exported include all the incremental data since the last completed export.
REM Saturday and Sunday incremental export will be employed once more.

REM This program can be used together with Windows plan and task utility. In that way,
REM the program can be enhanced with running by schedule.

1. Advanced/Variables, add a variable named <odbcUserDsnDir>, with a Text
type, Get variable from Registry, Default value "C:Program FilesCommon
FilesODBCData Sources", Root key: HKLM, Path:
HKEY_LOCAL_MACHINESOFTWAREODBCODBC.INIODBC File DSN, and Value name:
DefaultDSNDir. Thereafter, you can use <odbcUserDsnDir> to get file DSN’s
location.

2. Files to install, add the target dsn file, such as notesphr.dsn in my
example, specifying the target directory as <odbcUserDsnDir>. It will make
the dsn file copy from the installation packaget to the dsn default
directory. This is my dsn file’s content:

[ODBC]
DRIVER=Microsoft Access Driver (*.mdb)
UID=admin
UserCommitSync=Yes
Threads=3
SafeTransactions=0
PageTimeout=5
MaxScanRows=8
MaxBufferSize=2048
FIL=MS Access
DriverId=25
DefaultDir=C:Program FilesPhraseMemodatabase
DBQ=C:Program FilesPhraseMemodatabasenotesphr.db

3. In the notesphr.dsn, the last two lines should be changed in reponse of
the installation directory. We can do this with the help of System
changes/Text files. Click Add…, select Replace text action, specify the
filename, which is, in this example, <odbcUserDsnDir>notesphr.dsn, Search
text "DefaultDir=C:Program FilesPhraseMemodatabase" (quote marks
excluded) by replaced with "DefaultDir=<InstallDir>database" (quote marks
excluded), click ok to dismiss the dialog. Same as just now what we did,
replace "DBQ=C:Program FilesPhraseMemodatabasenotesphr.db" with
"DBQ=<InstallDir>databasenotesphr.db"

4. done. The installation will automatically copy your dsn file to the
target computer’s appropriate directory according to the computer’s
settings.
