Transmission Of Compressed Snapshots
Feb 2, 2007
I am using SQL2005 merge replication and have pull subscribers on a low bandwidth link
I am compressing the snapshot into an alternate folder. Files are not put into the default folder
When I start a synchronization, I would expect the cab file to be copied to the subscriber and then the files to be extracted locally at the subscriber in order to apply the snapshot
However, what appears to be happening is that the files are being extracted from the cab file on the publisher (in a UNC specified directory) and then copied in their uncompressed form to the subscriber - resulting in an extremely slow snapshot application.
Any ideas what I am doing wrong? I have read about the options for using FTP to transfer snapshot files, but I am not clear whether I have to use FTP in order to transmit a compressed snapshot. I don't want to use FTP unless I need to.
Any suggestions would be much appreciated

Noticed weird activity today with pull merge.
When your snapshot is set to be delivered via ftp and compressed in a cab file. If you add a new article to your publication and re-run the snapshot the agent will be unable to pull the snapshot down as it for some reason doesnt think its compressed. It is failing to find the scripts it needs inside the cab file despite the cab file existing in the correct location.
Here is the error.

Hi There
I have sent messages and they are all sitting in the transmission queue with a blank status, why is service broker not trying to send them ? They are no errors in the sql log. BOL says this is blank when it has not tried to send the message ? Service broker is definately activated in the database.
How do i force sql server to send anything in the transmission que ?
I have no idea what is wrong or where to check ?
Thanx

My normal scenario is tills sending live slaes to head office via service Broker queue. Sales are sent as soon as sale is made(normally tills on adsl lines), a loss of a Link to head office will still allow a sale to be made with the sale sitting in the transmission queue on the till but has not been commited at HO to adjust stock etc, until the link is back up. My worry is link goes down with several sales siting in the queue and then hardware failure. Is their a mechanism to backup the Transmission queue in the case of no link?
If you could back up the transmission queue at a till could i then take those messages and copy them into head offices queue for processing, this is in the case of my link to the till was down for a whole day but needed the daily sales from the shop,could i get the back up at end of the day and apply the messages at head office?
Any infomation on what would be the best way to recover from this event would be gratefully accepted.
any examples on a heartbeat to check the link status that is of very low cost between HO and tills bearing in mind HO needs to maintain status for large number of tills.

My transmission queue has lots of messages that will never, ever be delivered because the transmission_status = "The session keys for this conversation could not be created or accessed. The database master key is required for this operation."
How can I purge the transmission queue to get rid of this junk?

I have a strange problem with messages getting stuck in a transmission queue. The set up is as follows:
1. Client database behind physical firewall
2. Firewall rules forward inbound traffic to Client Database
3. Server database has route to firewall
4. Client and Server databases on different physical networks
Over the last couple of days, the IP address of the PC that has the Client database on it changed. Messages were getting through to the Server from the Client but not the other way round. I presume this also meant that message acknowledgements were also not getting back to the Client because messages were stuck in the Client transmission queue.
Looking in more detail at the queued messages at the Server side, it appeared that the Server had received the messages, processed them, and sent back an end conversation. The state of the conversation in conversation_endpoints was DISCONNECTED OUTBOUND. Which I assume means that these would never get through to the Client?
What is the correct way of dealing with this situation? I tried doing an end conversation with cleanup at the Server end but this is clearly wrong because this removes any trace of the conversation from the Server and means that the messages now get through correclty (again) and processed (again). Meaning that we now have duplicate messages in our database.
Any help would be much appreciated.
Thanks.

Hello,
I have a table of compressed data and am looking for an efficient way to expand the data for reporting purposes.
The table is used to store the number of hours a given contractor works and is stored in the following fashion:
cntHours
58
20
58
20
The first row represents the number of sequential days where an employee worked the same # of hours. Once the # of hours changes, a new record is created. In this simple example, the first row shows an employee working Monday-Friday (5) for a total of 8 hours each day. The second row represents the weekend (2 days) where the employee worked 0 hours.
What I need to do is explode this out to show 1 record per day. Ideally I'd like to write a function to do this as I would be linking to another table which has the start and end date for the contractor and would allow me to apply individual dates to each record based on the contractor start date through to the end date.
Thanks for any help you can provide!

I have a web application that sets up a query notification on a queue. Normal operation works fine, but for some reason the queue being monitored disables occasionally (even with the transaction, error message, and end dialog message) pattern set up as described in Remus' blog post. When the queue disables, everything goes insane and the transmission queue, left unchecked, fills up the transmission queue with hundreds of thousands of PostQueryNotification messages. Am I doing something wrong? What should I do to mitigate this because it IS possible that the queue might disable sometimes, and I don't want drive space eaten up on a low-end SQL Express machine, if it does. Also - second question - where is the transmission queue storing all these messages? TempDB?

I just completed a copy-Only compressed backup of a DB (with a FULL Recovery Model ) on SQL Server 2012 and the resulting backup (the bak file) is 1/100th the size of the data & log file. Is the compression in SQL Server 2012 just that good or did something else happen that I did not catch? Below is the T-SQL to re-create the backup. The size of the data file is 750MB and the log file is 75GB and is %95 used according to the SQLPERF command.
Does the compression in SQL Server 2012 simply that good
BACKUP DATABASE [MYBIGOLEDB] TO DISK = N'Z:Microsoft SQL ServerMSSQL11.MSSQLSERVERMSSQLBackupMYBIGOLEDB_20150611.bak' WITH COPY_ONLY, NOFORMAT, INIT, NAME = N'MYBIGOLEDB-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, COMPRESSION, STATS = 10

One way to save storage space is to put the SQL data files into a compressedfile. Has anyone got any idea how this will affect the query speed?

Hi,
I have a server in our central location which is a compressed snapshot publisher. I have 2 push subscribers in remote locations on very slow WAN links. I would like the snapshot cabinet file to be uncompressed at the subscribers location rather than the publisher location. Is this possible with push subscribers? I want to manage the pushing of data to the remote subscribers from the publisher location.
I understand the default with push subscriptions is to uncompress the cabinet file at the publisher location.
Thanks,
Mark.

Hi everyone,
already tried this in other SQL forums, but maybe i have some luck here.
I need mainly to restore database backups from customers. They arrive in all kind of formats (zip, rar, gz). I'd like to be able to restore those directly from the compressed file, because i'm talking up to 7GB rar files which take a while to uncompress in a separate step.
I'm working for 6 years in R&D environments, but mostly on Linux/Oracle where this is an easy task using pipes, but i haven't found a sinlge web page, post or even script to do this with MSSQL. The VDI is not really what i'm looking for, so aren't backup software like SQLBackup, Litespeed etc. because i can't force the customer to use those.
Anybody any idea or even the same problem maybe with solution?
Thx.

I am trying to read a 36 byte files that contains compressed data. I create my Flat File data source and SSIS reads it fine UNTIL it hits a x00 in the file. Then it stops reading and I can't get any data after it. There is data after the x00. Here the entire hex string: C7 C7 CF 6A 00 00 05 02 3D 03 21 01 E0 02 00 00 00 00 00 00 00 00 3D 3C 1E FD 02 C8 00 00 00 AE 41 E3 28 7C
To test, I changed the two x00 in bytes 5 and 6 to x01 and SSIS read until the next x00.
Anyone have any ideas?
Thanks,
Jack Lavender

I want to use SSB as a mean to thread multiple SP invocation of the same procedure.
When I launched the initator processes it created in the transmission queue error messages saying for each of them that it is an invalid target service name.
The view (sys.transmission_queue) records them in this way in the status column:
"The target service name could not be found. Ensure that the service name is specified correctly and/or the routing information has been supplied."
Services and queues and activation procedure are all defined into the same database.
I drop services and queues, and i tried to create a service with the initial wrong name. Nothing happened.
Thanks vour your help

Hi all,
I am trying to use bcp to output data to a compressed (zipped) folder.
The bcp command is called from a step in scheduled job in SQL 2005 (T-SQL) similar to:
SET@chvCommand =
'bcp [working_t] out D:EprojectsEdataCdata200701.dat'
+ ' -c -STPISQL -T'
EXECUTE master.dbo.xp_cmdshell @chvCommand, NO_OUTPUT
.... where Cdata is a compressed (zipped) folder.
The scheduled job seems to work without errors, but afterwards there is nothing in the compressed folder.
If Cdata is a regular folder everything works fine.
Thanks for you insight.

I have this bcp
EXEC xp_cmdshell 'bcp "SELECT top 10 * FROM [db].dbo.[u_activity]" queryout "C:bcpCustomers.csv" -c -b 10000 -t~ -S 10.20.8.149 -U user-P password'
which throws the data into a csv, but the issue is I also need to compress the file down in a .rar file,
can this be done in a SP while still executing the above bcp ?

I have an issue in my production , SQL server 2008 R2 , in Error log it is said “ An error occurred in dialog transmission Error : 9655 , State : 3 and Error : 9736 Severity : 16 State 0
I checked in sysmessages , it is said :” The transmission queue table structure in database is inconsistent. Possible database corruption “
So do you think I need to run DBCC checkdb ? Should I run it after working hours or it is fine within working hours ?

I have a question about SQL Service Broker.
Here are the steps I use to produce the issue.
1) I drop the Service Broker on the Receiver by running the following sql script:
if exists (select * from sys.services where name = N'//TyMetrix360Audit/DataWriter') drop service [//TyMetrix360Audit/DataWriter]
2) I send some messages using the SQL Service broker on the sender side
3) The messages I send stay in sender transmission queue. Here is an example of what my transmission queue looks like after running select * from sys.transmission_queue on the sender.

Service Broker received an error message on this conversation. Service Broker will not transmit the message; it will be held until the application ends the conversation.
The main point is that the sys.transmission queue retains the messages with the error 'Service Broker will not transmit the message; it will be held until the application ends the conversation.'
4. I execute the following sql statment on the sender:
select * from sys.conversation_endpoints
and see that the conversation that sent the messages are in state 'ER'
5. I then recreate the receiver with the following script:
create service [//TyMetrix360Audit/DataWriter] authorization dbo on queue dbo.TyMetrix360AuditQueue([//TyMetrix360Audit/Contract])
6. I send some more messages and see that the new messages are being received and processed correctly.
7. But what of the messages stuck in the sender transmission queue. How are these messages to be resent? Since the conversations are in state 'ER' it seems they are not being resent. Do I need to write a custom SQL script to resend them? I do not want to end the conversation because the message will be lost and not resent.
So, in conclusion, the main question is:
When the receiver goes down, or the receiver service broker simply does not exist and messages pile up the sender transmission queue like in my example how do these messages get resent when the receiver is restored?
By the way when I run
select service_broker_guid from sys.databases where database_id = db_id()
I get the same GUID after the server is restored.

I have created a new report.what i do in application is i compress the image and save it in database.now i need to retrieve the compressed image and display in the report. I have used the following code to decompress the binary data save in the image.
I dont know after that what should i do. How to show the picture in SSRS Report. I need to show picture in many reports.one of my doubt is how to call this function in SSRS Report. The function accepts input as byte but in database the column in varbinary.
Should I convert the input type of function to varbinary instead of byte array?
Public Function Decompress(ByVal arr As Byte()) As Byte()
Dim notCompressed As Boolean
notCompressed = False
Dim MS As MemoryStream
MS = New MemoryStream()
[Code] ....

Here is a description:
1. drop receiver side service broker with sql command : drop service [//TyMetrix360Audit/DataWriter]
2. send a message from the sender.
3. now the sys.transmission_queue on the sender keeps the message.
The relevant tables on the sender and receiver no look like this:
the following summarizes the transmission queue on the SENDER:
conversation handle message_body transmission status
5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 my message in binary, ie 0x.F4E1.... <blank>
the following summarizes the sys.conversation_endpoints on the SENDER:
conversation handle conversation_id state
5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 461891C8-5D53-4D89-A7C6-097FE2EDB22A CO
the following summarizes the transmission queue on the RECEIVER:
conversation handle message_body transmission status
5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 message body of error message...... One or more messages could not be delivered to the local service targeted by this dialog.
the following summarizes the sys.conversation_endpoints on the RECEIVER:
conversation handle conversation_id state
5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 461891C8-5D53-4D89-A7C6-097FE2EDB22A DO
What do I do now?
There is a message stuck in the sender transmission queue. You responded in my last post that I need to do a RECIEVE on the sender and end the conversation myself? This is not helping me. I am still confused about the answer to this. Can you provide some sort of code outline or steps to resolve this issue. As of now I do not know how to resend my messages stuck in the sender transmission queue and they can not be lost when the conversation is ended.
Also, I thought SQL Service broker was supposed to hadle things like this. It is common for the receiver to not be there. In this case the messages should resend automatically once the receiver is back up. Please help as there is no documentation online about how to resolve this issue and your last response was not adequate.
Thanks

Hi, I am trying to lean ASP.NET. So I was trying to install SQL Server too. But, I could not install. The aleart box popped up:
"SQL Server set up cannot install files to the compressed or encrypted folder: C:Program FilesMicrosoft SQL Server"
Before this, I also got a warning that the hardware of my computer does not meet the hardware requirement.
I would like to know how I can install SQL Server into my computer. Or, shouldn't I do that? To learn ASP.NET I want to have a database ready. If I can not use SQL Server, I may try Access or something smaller...
Thanks in advance.

Scenario: (1) Initiator/Target are running on different machines; (2) Target is on SQL Standard Edition with service pack 1; (3) Initiator ends the conversation.
If Initiator is running on SQL Express Edition with service pack 1 or 2, Send message? and End conversion? will introduce two messages in initiators sys.transmission_queue. One is empty message with correct message type; the other is empty message with no message type. Both of them are from the Target to the Initiator.
If Initiator is running on SQL Standard Edition with service pack 1, with same stored procedure (attached below), there is no message left in initiators sys.transmission_queue.
We like to find the way to make Initiator on SQL Express Edition acting same as it on SQL Standard Edition, namely not left messages in the initiators sys.transmission_queue
CREATE PROCEDURE [dbo].[CreateMessageForQueue]
@message varchar(max)
AS
BEGIN
SET NOCOUNT ON;
DECLARE @handle UNIQUEIDENTIFIER;
BEGIN DIALOG CONVERSATION @handle
FROM SERVICE [TCP://Initiator:4321]
TO SERVICE N'TCP://Target:4567'
ON CONTRACT LogContract
WITH ENCRYPTION = OFF;
SEND ON CONVERSATION @handle
MESSAGE TYPE LogMessage(@message);
END CONVERSATION @handle
END
Thanks,

Have 3 reports that runs using a shared schedule to generate historic snapshots. This has be working for months and months but out of nowhere it changed.
So now when ever the schedule runs it will generate the historic snapshot for 1 report but NOT the 2 remaining. As a strange twist the report that is successful changes from time to time...
SQL Server 2000, RS+SP2.
Any ideas?
Thanks
Regards
Jonas

We will soon be going to a new ERP system using MS SQL 2000. I'm looking into possible backup strategies. The database size will be about 50 Gigs.
We have a SAN, which the new ERP system will be backed up on. I know a little about a SAN, but I need to make decisions about the types of backups to make. We can have 10 active snapshots, so I could use snapshots during the day as a point in time backup. I could also use the SAN snapshot instead of using a full backup. Would it be safe to use the SAN snapshots instead of the normal SQL Server backups? Im not sure how long it will take to do a full SQL Server backup because the server is still in testing mode. Im not getting the big picture about when to use snapshots and when to use regular SQL Server backups.
Is it possible in Windows 2000 Server to stop the transactions and flush the buffers for a few seconds to do a snapshot? From what I understand, the database could be left in a suspect state if you use snapshots to restore a database.
Thanks in advance for any help!

I think I've read some conflicting advice in BOL. Maybe someone can clarify it for me.
Under "Database Mirroring and Database Snapshots" it says:
"You can take advantage of a mirror database that you are maintaining for availability purposes to offload reporting. To use a mirror database for reporting, you can create a database snapshots on the mirror database and direct client connection requests to the most recent snapshot"
To my mind, to enjoy a noteworthy performance gain, that mirror database would need to be on another server.
But then you read under "Database Snapshots":
"Multiple snapshots can exist on a source database and always reside on the same server instance as the database."
So how do you get the snapshot to the mirror?

HiWhat would be the quickest way to create a backup and revert programon an sql (2000) database?- Can you create a transaction on a database, regardless of theconnections and thenrollback it all via an external program- Could you monitor the changes with profiler and then reverse those?- If desperate, could you backup the db from a tool and then restoreit? (too slow to be practical?)Not sure how to do this so any offers would be appreciatedta

If multiple snapshots for the same report attempt to generate at the same second, is there something in place to prevent them from conflicting with each other?
Our SSRS 2005 application will use a console app that we are writing to change the default parameters on each report and call the CreateReportHistorySnapshot method. This application will be multi-threaded, so there is a possibility that multiple versions of the same report with different parameters will attempt to run at the same time. We need to be sure that these snapshots will not conflict and return the appropriate SnapshotHistoryID for that report run.
From looking at the History table in the ReportServer database it looks like there are uniqueIDs and other keys that would prevent duplicates, but what if the requests come in at the same time? Is SSRS 2005 smart enough to delay for a second so that there is not a duplicate? Since the way you reference these snapshots in your URL is with the Snapshot Time in UTC format, that only goes out to full seconds (2006-05-02T00:00:00).
Sorry for the length, but I could not think of how to condense this.
Thanks,
Steve

Hopefully not too much of a stupid question.
At the moment, we are using SSRS to report off an Oracle database, if we take a snapshot of the data on the Oracle database and put it within SQL, will we expect an increase in performace/response.
And is it a good idea to keep the snapshot in the same place where SSRS is installed?
Thanks in advance.

I want to share one of my doubt about SSRS and report server,
if i use snapshots or cache to my reports in report server, is it going to make increase in performance?
if it is going to make increase in performance,then SQLSERVER DATABASE is going to have any burdens,
means is it going to down the performance of Database?
Pls give me Responce to my Questions....

Hi
I am creating a full Merge replication setup between two servers
Is there any way that I can set it up so that I do not have to create a snapshot.
Ie I would gurantee that the data and structutre is EXACTLY the same on both the subscriber and the publisher.
The problem is that my data base is over 4GB and it is quicker for me to get the data from one server to the other by doing a backup and restore.
I am using SQL 2005 with the latest SP
Cheers
Ants
