最近服务器执行收缩日志文件大小的job老是报错

我所用的一个批量收缩日志脚本

USE [master] GO /****** Object: StoredProcedure [dbo].[ShrinkUser_DATABASESLogFile] Script Date: 01/05/2016 09:52:39 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROC [dbo].[ShrinkUser_DATABASESLogFile] AS BEGIN DECLARE @DBNAME NVARCHAR(MAX) DECLARE @SQL NVARCHAR(MAX) --临时表保存数据 CREATE TABLE #DataBaseServerData ( ID INT IDENTITY(1, 1) , DBNAME NVARCHAR(MAX) , Log_Total_MB DECIMAL(18, 1) NOT NULL , Log_FREE_SPACE_MB DECIMAL(18, 1) NOT NULL ) --游标 DECLARE @itemCur CURSOR SET @itemCur = CURSOR FOR SELECT name from SYS.[databases] WHERE [name] NOT IN ('MASTER','MODEL','TEMPDB','MSDB','ReportServer','ReportServerTempDB','distribution') and state=0 OPEN @itemCur FETCH NEXT FROM @itemCur INTO @DBNAME WHILE @@FETCH_STATUS = 0 BEGIN SET @SQL=N'USE ['+@DBNAME+'];'+CHAR(10) +' DECLARE @TotalLogSpace DECIMAL(18, 1) DECLARE @FreeLogSpace DECIMAL(18, 1) DECLARE @filename NVARCHAR(MAX) DECLARE @CanshrinkSize BIGINT DECLARE @SQL1 nvarchar(MAX) SELECT @TotalLogSpace=(SUM(CONVERT(dec(17, 2), sysfiles.size)) / 128) FROM dbo.sysfiles AS sysfiles WHERE [groupid]=0 SELECT @FreeLogSpace = ( SUM(( size - FILEPROPERTY(name, ''SpaceUsed'') )) )/ 128.0 FROM sys.database_files WHERE [type] = 1 SELECT @filename=name FROM sys.database_files WHERE [type]=1 SET @CanshrinkSize=CAST((@TotalLogSpace-@FreeLogSpace) AS BIGINT) SET @SQL1 = ''USE ['+@DBNAME+']'' SET @SQL1 = @SQL1+ ''DBCC SHRINKFILE (['' + @filename + ''],'' + CAST(@CanshrinkSize+1 AS NVARCHAR(MAX)) + '')'' EXEC (@SQL1)' EXEC (@SQL) FETCH NEXT FROM @itemCur INTO @DBNAME END CLOSE @itemCur DEALLOCATE @itemCur SELECT * FROM [#DataBaseServerData] DROP TABLE [#DataBaseServerData] END

幸亏报错信息还是很全面，根据报错信息找到相关的数据库，执行一下DBCC LOGINFO

dbcc loginfo(N'cdb')

发现确实只有两个VLF文件，不能再收缩了，因为是批量脚本，当其中有一个库失败之后，后续的库就不会再进行收缩操作

这里只要加上数据库的VLF数量的判断就可以了

本文写的不好，还请各位大侠提出宝贵意见，如有好的解决方案欢迎分享，大家共同学习进步。
