脚本将多个数据库日志文件移动到另一个磁盘

Question

我有许多数据库需要将其日志文件移动到新驱动器。 有脚本可以在任何地方执行此操作吗？ 有点像

对于每个用户数据库... alter database ...脱机...将日志文件移动到T：...

Answer 1

几年前我不得不这样做。

您需要更改@DestinationFolder值并调整查询以过滤dbs。

目前，这会将所有用户dbs的日志移动到@DestinationFolder位置。 我建议注释掉所有的exec sp_executesql @CMD命令并运行，以验证所需的命令是否正确：

USE [master]
GO

CREATE proc [dbo].[MoveLog]
as

--enabling xp_cmdshell will be required to do the file move
exec sp_configure 'xp_cmdshell', 1;
reconfigure;


declare @DBName as varchar(128);
declare @LogicalName as varchar(128);
declare @FileLocation as varchar(128);
declare @FileName as varchar(128);
declare @CMD as nvarchar(256);
declare @SourceFolder as varchar(128);
declare @DestinationFolder as varchar(128);

SET @DestinationFolder = 'E:\MSSQL\LOG'; -- Change this to the correct destination folder

BEGIN TRY

declare Db_cursor Cursor forward_only for
   select name
   from sys.databases
   where owner_sid  0x01;--user dbs only

OPEN Db_cursor;

FETCH NEXT FROM Db_cursor 
INTO @DBName;

WHILE @@FETCH_STATUS = 0
BEGIN

    set @CMD = 'ALTER DATABASE [' + @DBName + '] SET SINGLE_USER WITH ROLLBACK immediate';
    Exec sp_executesql @CMD
    RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT ;

    set @CMD = 'ALTER DATABASE [' + @DBName + '] SET OFFLINE ';
    Exec sp_executesql @CMD
    RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;

    SELECT @LogicalName =name, @FileLocation=physical_name, @FileName = reverse(left(reverse(physical_name), charindex('\', reverse(physical_name)) -1))
    FROM sys.master_files
    WHERE type_desc = 'LOG' and database_id = DB_ID(@DBName);

    --move the log file
    set @CMD = 'exec xp_cmdshell N''move "' + @FileLocation + '" "' + @DestinationFolder + '\' + @FileName + '"''';
    Exec sp_executesql @CMD
    RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;

    SET @SourceFolder = REPLACE(@FileLocation,@Filename,'');

    /* Update the system catalog */
    set @CMD = 'ALTER DATABASE [' + @DBName + '] MODIFY FILE ( NAME = [' + @LogicalName + '], FILENAME = ''' + @DestinationFolder + '\' + @FileName + ''')';
    Exec sp_executesql @CMD
    RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;

    set @CMD = 'ALTER DATABASE [' + @DBName + '] SET MULTI_USER';
    Exec sp_executesql @CMD
    RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;

    set @CMD = 'ALTER DATABASE [' + @DBName + '] SET ONLINE';
    Exec sp_executesql @CMD 
    RAISERROR ('Executed command: %s',0,1,@CMD) WITH NOWAIT;

    FETCH NEXT FROM Db_cursor 
    INTO @DBName;
END

CLOSE Db_cursor;
DEALLOCATE Db_cursor;
--GO
END TRY

BEGIN CATCH
   IF (SELECT CURSOR_STATUS('global','Db_cursor')) >=0 
   BEGIN
      DEALLOCATE Db_cursor;
      RAISERROR ('Db_cursor Deallocated in catch',0,1) WITH NOWAIT;
   END

   SELECT ERROR_LINE(),ERROR_MESSAGE();

END CATCH

exec sp_configure 'xp_cmdshell', 0;
reconfigure;

我知道这是一个很老的帖子。 但我认为最好在此发布此解决方案，而不是在新帖子中发布。

我需要上面的解决方案，但由于减少了停机时间（以上脚本只抓取一个文件），因此同时更改了更多ROWS和LOG文件。 如果Destinationlocation与SourceLocation相同，我添加了测试代码以不使用数据库Ofline。 您可以为ROWS和LOG文件定义不同的目标/分区。

我错过的一步是处理文件ACL。 在某些情况下，需要一个超过默认的ACL，特别是对于服务或实例帐户。 我添加了这一步。 ACL设置由位于@copyaclScriptLocation的简单Powershell脚本处理。脚本来自Jeffrey Snover

<#
.SYNOPSIS
Copy the ACL from one file to other files

.DESCRIPTION
Takes a file and copies its ACL to one or more other files.

.PARAMETER FromPath
Path of the File to get the ACL from.

.PARAMETER Destination
Path to one or more files to copy the ACL to.

.PARAMETER Passthru
Returns an object representing the security descriptor.  By default, this cmdlet does not generate any output.

.INPUTS
You can Pipeline any object with a Property named "PSPath", "FullName" or "Destination".

.EXAMPLE
PS> Copy-Acl Referencefile.txt (dir c:\temp\*xml)

.EXAMPLE
PS> dir c:\files *.xml -recurse | Copy-Acl ReferenceFile.txt

.LINK
Get-Acl
Set-Acl

注释：/ *获取复制原始ACL的dataroot位置* /
我知道XP_REGREAD部件不是一个很好的解决方案，最好用Powershell完成，但我不知道比获得dataroot目录更好的方法。 此代码段用于SQL实例，很容易更改为默认路径
