Using BACKUP From OSQL And Wait For It's End
Aug 31, 2006
I'm writing a small vbscript to backup a db and some related files, so I used a WSShell calling OSQL to run a Sql BACKUP command, then after it's finished I XCOPY the resulting file plus some other related files. But the problem is that OSQL ends it's execution as soon as the BACKUP command is sent to SqlServer, not when the backup itself ends.
Anyone knows how to synchronize the two? How to wait, inside OSLQ, for the end of the BACKUP execution?
TIA

I'm experiencing a very annoying failure when trying to do a backup - I hope you can help where others (including me) have failed.
The setup is a SharePoint Portal Server 2003 version 11.0.8126.0 running on Windows server 2003 Standard edition Service pack 1; it has a SQL-server 2005 version 9.0.2047 running on Windows server 2003 Standard edition Service pack as a back-end.
When I issue a backup of the SharePoint database XXX_SITE which holds round 4 gb. of data (mainly documents) the backup process hangs with a Wait Type 'MSSEARCH', it makes no difference whether I issue it as a single job, or through a maintenance plan.
I tried to stop the MsSearch service on the SharePoint-server, and disabled the Full-Text search on the database but it makes no difference.
The only way I can get a backup is to reboot the server on which SQL-server resides (restarting the SQL-server makes it rather unstable), and do a manual back-up shortly after.

Hi all,
Am extremely new to SQL and have come stuck writing a DOS script that works well if the DB's are on the same server. My problem is that one of the DB's the script is to manage is on another server and I've been losing sleep trying to work out how to resolve this.
I'm trying to keep (if possible) the script as simple as I explain below.
For the successful DEMO backups, I have the following ....
The SQL batch file (%SQLFile%) reads:
backup database DB_DEMO to DISK = 'C:DA_InstallsBOSDEMO estingackupsdbaseDB_DEMOFri.bak' with init
go
In the DOS script, I have:
osql -S %DBSrvr% -E -d %SQLDatabase% -n -i %SQLFile% -o %SQLBackupLog% >> %OutputLog%
And this is successful, as the script and the DB reside on the same server. However I'm troubled by how I connect to the DB_LIVE db on another server and write the backup to the same server the script is run from.
Any help is really appreciated.
Cheers,
Cameron

Will osql product an SQL backup? By this I mean a text file with thetransact-sql in it so I can use it to recreate the database elsewhere?Thank you.

I am running into problems while running a large procedure, and i think it may have something to do with a PAGEIOLATCH_SH wait problem.
My server, whose sole purpose is to run this one procedure, is doing plenty of disk i/o, and the CPU’s bouncing around, so I assume it’s working. But when I look at its process info, it seems to be sleeping a lot of the time on PAGEIOLATCH_SH. No other users are in the DB, so I'm quite confused. I don't find much info on this anywhere, so any insight would be very appreciated.

I'm new to SQL Sever 2005 and I'm trying to do what Informatica (Power Center - ETL) is trying does.
I have created a work flow and it is scheduled to run at every night 1:00 AM .The process is to load a flat file (CRV.data) into the database from a shared location.The flat file is transfered from a 3rd party and once the file transfer is complete it will create a indicator file (0 byte eg: CRV.DONE file) which indicates the CRV.data transfer is complete.
In my workflow I will be waiting for the CRV.DONE indicator file and once it is avaiable I will start loading the CRV.data and once the load is completed I will delete CRV.DONE file and be ready for the next day load.
Please let me know if there is any way in SQL Server 2005 to achieve it.Thanks

Hi. We are migrating a mainframe datacom database to SQL Server. One of our client-server applications already uses SQL Server. This application uses a middleware product to query and update the datacom database being migrated. We are considering using Service Broker to replace the middleware.
In many cases the client does not need a response provided the message is queued and will eventually get delivered. However, in some cases the client would like to wait for the message to be processed before proceeding. Is there an easy way to both submit and optionally wait for a response - with data - in a single stored procedure? If client does not want to continue to wait, is there a way to use a procedure to check for the returned message later?
We have not used Service Broker before and are doing for a "sanity" check before proceeding. We do not want to tightly couple the two databases at this time.

I have installed performance dashboard on 2 different servers. The first server have User Session CPU Time 71% and Wait Time =28%, The other server have Cpu Time of 20% and Wait Time of 79%. Have I understand that stands in SQL Server Waits And Queues that I have some typ of wait problem in my second server?
Then I tries to run this
Select
'%signal waits' = cast(100.0 * sum(signal_wait_time_ms) / sum (wait_time_ms) as numeric(20,2)),
'%resource waits'= cast(100.0 * sum(wait_time_ms - signal_wait_time_ms) / sum (wait_time_ms) as numeric(20,2))
From sys.dm_os_wait_stats
First Server
%signal waits %resource waits
--------------------------------------- ----------------------------
0.07 99.93
Second Server
%signal waits %resource waits
--------------------------------------- ----------------------------
0.12 99.88
Messy in my head€¦ Help please
My second server have
CLR with 50% in the historial wait. Rest in Sleep

I'm doing an update on a table with about 113m rows, the update-statement is fairly simple: update tab set col = null where col is not null.
The col column is mostly null.
Sysprocesses shows three rows for this statement: 1 CXPACKET (its a dual processor, 2000 box with sp3 installed), 2 PAGEIOLATCH_SH (waitresource is filled). My guess would be that the where-clause is executed in a seperate process blocking the update.
I changed the statement into update [...] set col = null; sysprocesses shows one row with PAGEIOLATCH_SH. Executing forever.
I checked other processes including those outside sqlserver but none are using the db, let alone accessing the table involved. Even restarted sqlserver to be sure there's no dead process blocking the update. Didn't help.
So I added a search condition to the where-clause, involving a clustered index in order to reduce the rowcount. The execution plan shows a 97% hit on the clustered index, but sysprocesses shows the three rows again...
So far the profiler didn't help me out either: there's a SP: CacheInsert on the update-statement... then nothing.
What should I do?

I have an ASP.NET web application that hangs on a single database UPDATE command for 5+ minutes. I can see this occur in SQL Profiler. This is a one row UPDATE statement on a small table (~600 rows). There are no JOINs or sub queries. There are no other users using the system. During this 5+ minutes, I can see the job in Enterprise Manager with a wait type of NETWORKIO. Since both IIS And SQL Server are running on the same system, the network shouldn't be an issue. Any ideas?

I setup a SQL Agent to send me an email when the Average Latch Wait Time is greater than 300ms. Now I receive an email every 15 seconds stating that the current ALWT is 3916ms. That value never changes with the emails. However, the perfmon shows nothing at all (shows zero).
I also have a Buffer cache hit ratio of 2848.00.
These numbers are when there is NOBODY on the DB at all It is just sitting there. When I reboot the server, as soon as SQL starts it starts to send the emails again.
Server: Intel Xeon Quad Core 2.66
RAM: 4GB (with /3GB in the boot.ini)
RAID 1: OS
RAID 1: Data (DB and logs)
CPU Utilization: 0-1%
RAM Utilization: 527MB
OS: Server 2003 R2 With SP2
SQL: 2005 Standard with SP2
How can I determine if the ALWT is really 3916?
I executed 'Select * from sysprocesses where SPID>50 and waittime>0'
Which showed;
BROKER_RECEIVE_WAITFOR
waittime=110640ms
waittype=0x0075
status=suspended
program_name=DatabaseMail90 - Id<3780>
Any assistance is greatly appreciated.
Thank You
Magnum

Hi,
I have a data-flow-task that imports data to sqlserver.
Now I want to check, if a special column of an imported record is null.
If yes, I have to wait 10 minutes and jump to the data-flow-task again. (Cjeck and wait).
How can I do this with the integration services?
Thanks
Gerd

We have a few SSIS jobs that we are currently manually kicking off after we are sure that certain AS400 jobs have run. We want to completely automate this process, so that we don't have to babysit. What is the most efficient way to do this? In the past (on SQL Server 7 no less) I've seen the 400 job setting a flag to 'Y' in a 400 file, FTPing it down to a flat file, and then the SQL job running every five minutes checking the flag. When it was 'Y', the SQL job would run. We do not have the option of using FTP here. Any suggestions would be appreciated! After the job runs, we'd like it to kick off a report as well

So, I'm fairly new to SQL, and I'm working with a SQL2k5 Database with pre-made packages and what-not. This database was setup before I started this job, and now I'm trying to improve part of the processing in SQL, and so far so good, but I can't figure a couple things out.
The main problem is when I start a SQL command to launch a DTS package from a .sql file, how can I make it wait for the package to complete or fail before moving onto the next part of the .sql script? Hope it's a simple question, I've just taught myself enough SQL to get by in a couple of weeks.
Thanks!

Good morning,
I will start off with the default warning message: I am a beginner. That said, I have an SSIS process that calls an external executable to transform a data file through a homegrown C program. (This will eventually be converted, but for the moment needs to remain.) The end of the run creates a *.done file. How do I use the SSIS tasks to pause/wait, checking periodically, for the existence of this file before continuing with processing tasks? I apologize if this is easy, but I am stumped.
Thanks in advance,
Roger

CXPACKET wait type current makes up 63% of all the wait types which is causing latency. I need to identify the specific workloads responsible for waits so I can optimise or MAXDOP them. I already know how to retreived the top IO, CPU, Memory consuming queries but how do I identify the statements and order them by wait time?
Can someone point me in the direction of a command, DMV or will the top CPU list be adequate?
Thanks

Hello,
It seems strange to me that once the UNION ALL component waits for at least one row from each input buffer before it puts anything into the output buffer (that's the behaviour that I have observed anyway).
Why does it do that?
Thanks

I would like to know what a particular session is waiting on (cpu, io, memory etc).
For that I try to figure out how to use extended events. I would prefer to avoid the use files written to db-server, why I tried "histogram target".
Well my attempt does not produce usefull output,
-- check current event sessions
SELECT a.name,
CASE WHEN b.name IS NOT NULL
THEN 'Started'
ELSE 'Stopped'
END AS current_state
[Code] ....
The intention was to get a pareto chart, to see the top wait events in the session. I would also like to see amount of cpu used. Based on this tuning effort could be prioritized.

OK, I know this is out there all over and yes I did a search for this topic; however, I am confused about tables with an image data type and with moving text file group to another filegroup.
Here is what I have:
I have a table storing imaged documents and has become very large. I want to move the table to another filegroup. The table is created like this:
USE [PD51_Data]
GO
/****** Object: Table [dbo].[SCANNEDDOCUMENTS] Script Date: 05/13/2008 14:52:40 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[SCANNEDDOCUMENTS](
[DocID] [int] IDENTITY(1,1) NOT NULL,
[CaseID] [int] NOT NULL,
[DocName] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[Doc] [image] NOT NULL,
[DocLocation] [varchar](255) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[DocNotes] [text] COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[TopicID] [int] NULL,
[ScannedDocumentsCheckSum] [varchar](128) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,PRIMARY KEY CLUSTERED
(
[DocID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
ALTER TABLE [dbo].[SCANNEDDOCUMENTS] WITH NOCHECK ADD CONSTRAINT [ISCANNEDDOCUMENTS2] FOREIGN KEY([TopicID])
REFERENCES [dbo].[TOPICS] ([TopicID])
GO
ALTER TABLE [dbo].[SCANNEDDOCUMENTS] CHECK CONSTRAINT [ISCANNEDDOCUMENTS2]
On a test DB, I moved the clustered and nonclustered indexes to a secondary filegroup no problem, but it still shows to be stored in the primary filegroup. I read an article about having to create a new table in the secondary in order to move the images and text file group. Has anyone come across this?
Do I need to drop the clustered index and FK to move to a secondary filegroup?
Or
Do I create a new table into the secondary filegroup and then add the Clustered index and constraints?

For one of our SQL server 2005 Ent edition 64 bit SP4 which has transnational replication set up and used for heavy reporting, i was trying to counter out the performance of slow running queries which basically runs and get suspended and most often are seeing waiting:So i tried to analyse the wait stats and come up with below stats where ASYNC_NETWORK_IO dominated for a collection of two weeks data.

Hello,
I'm hoping someone can clarify what I am seeing below:
I have a SQL Server which the 2nd top wait state according to the SQL Server 2005 SP2 dashboard is "CLR_Auto_Event" and "CLR_Manual_Event". This server dosen't have CLR Integration enabled in "Surface Area Configuration", and we do not have any CLR applications. I've checked this dashboard many times and CLR never appeared before, and nothing has changed on the server interms of new databases, and we don't host any applications on the server. I ran a short profiler trace and didn't see any CLR Assembly Loads.
Is there something I'm missing....?

Is there a way to execute a stored procedure and have it move on without waiting for a response from the stored procedure. I am trying to create a button on a webpage that will execute a stored procedure but the procedure takes to long to run and my page times out. Instead I would like the button to start the procedure and the webpage look at a table of data. When the table of data is empty then I will know the stored procedure is complete. Is this possible?

We usually wait until a service pack has been released for a product like SQL Server before using it in production. Is this over cautious or the norm?
