robocopy tools(Windows2000 server shared folder access control copy )



As the data server is changed to another server machine. The shared source should be relocated to another server , but the access control rights should be maintained. Xcopy can do it in the same machine , but it can not support different machines copy action.
Howerver , there's another way to do it .Symantec Back up software can do it , but it nid you to pay, though there's trail period , but if we do it ourselves , whether there's another way to do it .
The answer is yes. There's another tools for it : RoboCopy.
Fist you have to select a diretory for the distination for the copied files :




Then choose which file you want to copy, after that you can do it yourself,
Then it will run the robocopy command to relocate the shared source to the distination you made.

Well done, there's no manual for the user but you ask them to support the server room . so wat will happen if they don't know how to solute the problem in KVM down.

how to restore database from sql server 2005 to SQL server2000

                       how to restore database from sql server 2005 to SQL server2000

想从sql server 2005 的数据库备份恢复数据到2000,会遇到错误 "Too many backup devices specified for backup or restore; only 64 are allowed.

(Microsoft SQL Server, Error: 3205)"

用detach和attach同样不行,"Error 602 Severity Level 21 Message Text

Could not find row in sysindexes for database ID %d, object ID %ld, index ID %d. Run DBCC CHECKTABLE on sysindexes."


 

 

How to Downgrade a Database from SQL Server 2005 to SQL Server 2000

As you may all know, SQL Server 2005 request a minimum of 8GB RAM to work… let say satisfactorily. I first didn’t knew that and after a while from the upgrade I did from SQL Server 2000 to 2005 my SQL Services were starting to crash three or four times per DAY!!! 

At first I thought I was being attacked, but soon I realized it was nothing like that. I then decided to downgrade to an SQL Server 2000 edition. Though I looked around the internet to find some information on how to do that, I got very disappointed when I realized that no actual documentation of any kind could be found for that. So I am posting this thread to inform you on the procedures I had to follow for this action. 

Before beginning I must assume, firstly that the user, who will attempt such thing, has a basic knowledge of SQL Environment, secondly that he has the two versions already installed (both 2000 and 2005), that a basic backup of the databases has been created and finally that all the 2005 SQL Server Users have been created at the SQL Server 2000 environment as well.

Step 1 Generating Scripts for the Database Elements and Structures

1) Right-click over the desired Database at 2005, Choose Tasks and the Generate Scripts (Option).

2) At the pop-up Dialog Box click at the Script All Objects in the selected Databases check box, to activate it and then Click the Next Button.

3) Set the following Elements to the following Values

a. Script Collation , set to TRUE

b. Script Database Create, set to TRUE

c. Script of SQL Version, set to SQL SERVER 2000

d. Script foreign keys, set to FALSE

e. Script Triggers, set to FALSE

Then Hit the Next button

4) Select the way the generated scripts should be saved (There are different selections. The most common one is Clipboard). Finally click the Next button till you reach the end.

5) Click Finish

After completing this procedure, we have to move to the SQL SERVER 2000 environment. Here, by using the Query Analyzer, we will have to run the scripts that were generated using the master database. Copy and Paste the script at the Query Analyzer and run it. After that the Structure of the Database will be created.

Be careful, the SQL Server 2005 Edition inserts the Views in a random place through the script. Therefore, all the scripts that are referred to the Views MUST be moved to the end of the script. If the Query Analyzer shows some errors do not be bothered. Delete all the elements created from the script and after you fix the code run it again.


Step2 Moving the data from 2005 to 2000

1) After completing the previous step successfully, moving the data follows. Right-click at the 2005 database you used to run the previous step and select Tasks and then choose the Export Data (option).

2) From the pop-up Dialog Box, select the Source Db and Click at the Next Button.

3) At the next step you will have to choose the destination server and the destination Database for the Data to be exported. Then Click Next.

4) A List of all the Source Database’s Elements will appear in the screen. Select one by one all the Elements you wish to move and for each one click at the button Edit Mappings (Located at the bottom right corner of the Dialog Box just under the Elements list). A new Dialog box will pop-up. Select the Delete rows in Destination Tables option and activate the Enable Identity Insert Option. (Remember to repeat this action for each of the selected Element from the list that will be moved.

CAUTION!!! A malfunction of the SQL Server 2005 has been found. Not sure why, after multiple tries I have observed that when I tried to move more than twelve Elements at once, the Export Data Wizard of SQL Server 2005 seemed to disable the Enable Identity Insert Option that was activated over the Edit Mappings Dialog Box. But if the number of the selected Elements is smaller than 12 no problem seemed to appear.

Step 3 Generating Scripts for the Database Foreign Keys and Triggers

Finally, to successfully finish the downgrade of the Database, the Triggers and the Foreign Keys of the DB must be produced. The procedure that should be followed is the one stated next:

1) Right-Click at the SQL 2005 Database and Select from Tasks Menu the Generate Scripts Option.

2) Using the pop-up Dialog Box make sure that the check box Script All Objects in the selected Databases is not enabled and hit the Next Button.

3) Set all the Elements on the List to a False Value except the ones that follow:

a. Include IF NOT EXISTS , set to TRUE

b. Script Owner, set to TRUE

c. Script of SQL Version, set to SQL SERVER 2000

d. Script foreign keys, set to TRUE

e. Script Triggers, set to TRUE

Then Hit the Next button 

4) After finishing reading the Elements of the Database, a new list will appear at the Dialog Box. Make sure that you select ONLY THE TABLES of the Database and hit the Next Button.

5) At the screen that follows hit the Select All button and the Next.

6) Select the way the generated scripts should be saved (There are different selections. The most common one is Clipboard). Finally click the Next button till you reach the end.

7) Click Finish Button.

After completing this procedure, we have to move to the SQL SERVER 2000 environment. Here, by using the Query Analyzer, we will have to run the scripts that were generated using the master database. Copy and Paste the script at the Query Analyzer and run it. After that the Foreign Keys and the Triggers of the Database will be created.

After these steps the database should be fully functional under the SQL Server 2000 edition.

During Export data from 2005 to 2000 ,there's may be some problem , wat i encountered is that though 2005 management info shows successfully exported, but it just export 1 record into the disternation table.

So inorder to solve the problem , you 'd better use the disternation database to import data from 2005 ,that will be much useful. And the problem solved.

Good luck!
