Classification Has Been Delayed Because The Routing Information...
Apr 25, 2007
Any ideas on why I get this message in the transmission status:
Classification has been delayed because the routing information is currently being updated.
I did create/drop some routes because I had pointed them to the wrong service, but that was some time ago.
I also just tried to restart the sql instance and it hung on stopping so I'm assuming something with the routing caused the issue.
Any ideas?
Thanks.

Hi all, thanks for reading.
Bit of a puzzler...
A customer of ours has reported a intermittent error using one of our applications to receive some stock.
Under normal circumstances the application updates about 10 tables in a single transaction, inserting to some, updating others. After the stock receipt they print off a Crystal report against the receipt data.
The customer is saying that (very) occasionally they perform a receipt (no errors) and print off the report (no problems) yet when they come to access the data some time later it is almost as if no receipt has been made.
I have seen their data and can see what they mean. None of the expected data updates seem to have taken place. And yet there is the report sat there, indicating that it must have...
Looking closely at the data I can see breaks in the sequencing in certain identity column-carrying tables, during the period when the stock receipt was made. To all intents and purposes, therefore, it looks as though a rollback has occurred.
Is this possible? Could a Crystal report show uncommitted data which is then rolled back? How 'long' can a rollback take? Can it be initiated in some other way?
NB: We have done all the obvious things like:
- checking they have received against the correct DB;
- checking that no app or procedure can remove data in this way.
- verified that the report is reporting from the correct place.
etc.
The 'missing' data is so perfectly removed, my instinct says it must be a rollback but I can't see how this can be (yet).
All suggestions gratefully received - how could I track down whether this was occurring? Or is it my fevered imagination?
Many thanks!!!!
pmb
ps: According to our records, this customer is running SQL 7 SP3.

Hello All,
Thanks in advance for your help.
I am wondering if there is a correlation between the size of a database and the amount of RAM required in the server. Here's what's going on:
NT4.0 SP 6a, SQL 7.0
2-800 MHz Pentium III Processors
512 MB RAM
Swap Files: two, divided evenly between two partitions, min 512 per partition (dynamic)
3- 9.2 GB Drives, RAID 5
SQL Database size: 2.5 GB
The SQL administrators have a scheduled job set to dump the database every four hours, so they have 6 of these dump files per day. Seagate Backup Exec v 6.? backs up those files every evening. Of course, this is a mission-critical application.
As the NT/Hardware administrator, I was tasked to flash upgrade all the hardware that could be flashed. That happened about three weeks ago. Ever since I flashed it, getting the data dumps has been an inconsistent process. Sometimes it works, sometimes it errors out. The error message is " Lost Delayed - Write Data: The system was attempting to transfer file data from buffers to (path). The write operation failed, and only some to the data may have been written to the file."
On and off during the day, you can't even copy a small file on the server without receiving the same message.
Before I flashed the server, it was blue-screening and needing to be rebooted about once every two weeks. Since I flashed it, the server hasn't been rebooted, because it hasn't blue-screened.
The database dumps are about 2 GB. We were thinking that the way the dump process worked was that a snapshot of the data was put into memory before it was written to disk. We thought since the dump size was larger than Physical Memory + Virtual Memory, that that could be causing the error.
What do you guys think?
1. Is dumping the database first the preferred way to get a backup, or should a backup directly to tape be scheduled instead?
2. Do we have enough RAM for the database?
3. Are there special settings we should set for the RAID controller card to maximize throughput for SQL?
Thanks again. I am definitely not a SQL DBA and any information you can provide would be really helpful.

Hello --I think this is the term for what I want (something that could be generatedin ACCESS using a pivot table, or, maybe Yukon).We have data for sales by sales people in sales regions. More than oneperson sells in a region.We want to display data as follows:salesperson's names----------- ----------- ----------- ----------- ----------- -----------region 1region 2 row/column values are sales amounts for person inthat regionregion 3We will add a WHERE clause for the period of time covered.I don't want to have to change the query if a new salesperson or new regionis added.Can this be done in SQL Server 2000, Analysis Services, OLAP, anywhere?Can someone direct me to examples of how to do this?Thanks for any direction.Larry Mehl

Hi,
I am studying data mining features of SSAS and for a workshop I've
created 2 views derived from vTargetMail view of AdventureWorksDW.
Train data consists every record except those in Pacific, and test
view consists only records from Pacific area.
1. I've created a mining structure based on Decision Tree and selected
BikeBuyer as predictable column.
2. According to input column suggestions, I've selected Age,

I can get training results in decision tree browser and dependency

Am I missing a step, or must I do some fine-tuning on (what)

Can anyone HELP!!
I have a system set up with 2 servers, the master server replicating the data to the backup server. Each server has two network cards, 1 which links directly to the other server.
The problem is the replication is being routed round the network making the direct link useless.
How can this be ammended!!
They are both logging into the same primary controler.
I am open to sugestions

Hi There
I cannot find anything online or in BOL about the proper format for a named instance in the routing address.
is it simply
ADDRESS = 'TCP://SERVERNAMEINSTANCENAME:4026'
or do you need to provide the port number for the instance.Not sure if TCP recognises the instance part?
Thanx

Hi
We are currently starting new project and evaluating possibility of using Service Broker in it but seems there could be some problems
We have a central server with a central database and several hundred of mobile? users. Information ( actually a subset which is specific to a particular user ) should be sent from/to central database and we wanted to use Service Broker for this.
When you set up a route in Service Broker you need to define Network address which I believe should be an IP address or DNS name.
The problem for us is that our mobile? users do not have static IP addresses and I am not sure we can assign a unique dns to all of them.
Mobile users can connect to internet in different placesŚ and hence get different IP addreses.
Is there a solution to this problem?
Rsgards,
Leonid.

Unable to access the 'T' database because no online secondary replicas are enabled for read-only access. Check the availability group configuration to verify that at least one secondary replica is configured for read-only access. Wait for an enabled replica to come online, and retry your read-only operation. Changed database context to 'T'.
I have 2 sql servers running in an AG group. SQL 2 is fully syncd and is used for read only reporting.The connection from the listener using ReadOnly works and connects to SQL 2. The problem is, when a database in SQL 2 is suspended from the AG group, the listener does not connect to the SQL 1 (primary).
The AG group is setup exactly like this:
Readable Secondary = Yes for both SQL 1 and 2, Availability Mode = Synchronous
why the listener does not connect to primary server?Connection in primary was set to "Allow read/write connections" for the AG. This meant "Connections where the Application Intent connection property is set to ReadOnly are not allowed. " Setting to "Allow All Connections" worked.

I've been reseaching on SSB and have read quite a number of posts on this forum that closely relate to what im trying to achieve. I have a solution im designing that ideally consists of a central server (SQLENTERPRISE) that will receive messages asynchronously from remote clients (SQLEXPRESS) spanning a wide geographical region over a GPRS virtual private network on a TCP/IP transport. This ideally is a star and spoke architecture and requirements dictate high level security, no loss of messages whatsover as well as high reliability and scalability.
To meet the security requirement in the context of the above scenario, i was thinking implementing both dialog and endpoint security using certificates would be ideal. I've downloaded some samples and have encountered problems simulating the above scenario on 3 machines (I Server & 2 Clients). Client1 sends messags successfully, the 2nd client doesnt possibly because the certificate on the server matches that to client1 since i ran that script first. How do i make it that the Server shares one certificate with all remote clients? Or is there a better way to configure SSB to work in this scenario?
Secondly i have hard coded the Server's IP Address in the Routes created on the Clients. Considering this is over a GPRS Virtual network, how can i make the clients dyamically "discover" the Server? The idea here is to make adding and setting up of new remote clients easy so that you can just plug them in to the existing network
Any help or pointers would be greatly appreciated.

I setup an AG with a listener (AO1) on three servers.
Server1 = Primary, Readable Secondary = No
Server2 = Secondary, Readable Secondary = Read-intent only
Server3 = Secondary, Readable Secondary = Read-intent only
Connecting to AO1 with default settings, I end up on Server1.
If I attempt to connect to AO1 with specifying ;ApplicationIntent=ReadOnly (with or without specifying the db name) in SSMS, still lands me on Server1.
Also on topic, in this scenario I would actually want Server1 to be a readable secondary (in the event of a fail-over). So If I did set it as Yes, even If I do get the issue above working, won't I always land on Server1 then?

Setting up Service Broker routes, endpoints and security is just too hard. One has to run pages and pages of Transact-SQL code just to get the Hello, world example work between two separate SQL Instances and the chances of making a mistake are overwhelming.
Well, not anymore! Ive just uploaded into the Service Broker team code gallery a new GUI tool for doing just that: easily configure two services to be able to have conversations. The tool uses the Service Listing concept. A Service Listing is like an identity card for a service. It is an XML document that contains all the necessary information needed to establish a conversation with that service. When two parties need to establish a conversation, they can exchange the Service Listings of the two services and the tool will create the entire infrastructure needed to establish the conversation. Optionally it can also create the message types and contracts supported by a target service in the initiator service database....

My application supports a single database connection and in the app console I can produce reports. If I include the app database in an AlwaysOn availability group with a read-intent replica will SQL automatically route the âselectsâ to that second instance thus offloading my applicationâs reporting activities or I need a separate db connection (maybe from a reporting app or cli) with a connection specifying read-only intent?

Having an annoying AG/AO problem with the read only routing side of it.
Let me give some specifics first:
2 SQL Server Instances, Not Clustered.
Availability Group is named 'Ireland'
There is a primary Replica and a Secondary Replica, named:
'IrelandPrimary' and 'IrelandSecondary'
There is a listener configured with the name 'ListenIreland' on Port 14330 (the two 3's are correct)
Read Only Routing URLS are configured as follows:
IrelandPrimary tcp://Ireland.dom.local:49891ALL
IrelandSecondary tcp://Ireland.dom.local:49841ALL
So now my problem:
When I try to connect using the ApplicationIntent=Readonly; or even using -K ReadONLY in sqlcmd I get the error telling me that my connection was actively refused.
This is connecting to the Listener, not the instance itself - that works fine. I'm at a bit of a loss now.
To explain what I am trying to achieve is a for a connection to be redirected to the secondary replica when its set for read-intent.
I've just noticed that it only fails when I specify ApplicationIntent=ReadOnly; If I omit the Intent It connects to the read-write database instead.

Hello,
I have some troubles with IBM WebSphere Application Server using MS SQL Server 2005 JDBC Driver. I always get the error e.g.
java.lang.SecurityException: class "com.microsoft.sqlserver.jdbc.SQLServerDatabaseMetaData"'s signer information does not match signer information of other classes in the same package
I found this Feedback but it seems to be closed.
A temporary solution for me was to delete the meta-inf directory of the JAR-File, but that can't be the solution.
Can anyone help me with this problem?

Remus,
thank you for your reply on (microsoft.public.sqlserver.notificationsvcs).
one more question :
Server_2 == Server_3
so I set up a route for db2:
CREATE ROUTE [rem_s2_route] AUTHORIZATION [dbo] WITH SERVICE_NAME = N'rem_s2' , ADDRESS = N'TCP://192.168.0.2:4022'
to create route for db3 (sql express) I tried
CREATE ROUTE [rem_s3_route] AUTHORIZATION [dbo] WITH SERVICE_NAME = N'rem_s3' , ADDRESS = N'TCP://192.168.0.2sqlexpress:4022'
this failed, what am I doing wrong or did I lost the plot? How do I diff beteen more than one instance of sql server on the same server? And can the port be the same on each instance of SQL Server?
thank you in advance

I have a report where the information is getting cut off the report.
At the beginning of or at the ending of the page it is dropping the information.
My layout setting are set 8.5in wide by 11in height. .5in for either left or right margin. 1in for top and bottom.
I run the report and I'm missing a record.
I adjust the height to 10in to force diffferent page breaks and it's there.
I have the setting in one of the groups set for a page break at end. If I uncheck that it doesn't help.Still no records.

Hi!This is a very simple question and I'm sure you guys will help me a lot.I'm using Visual Basic 2005 for programming. I have one table on my MS SQL 2005 database that has an int column with a counter that needs to be incremented when a user registers.So when reading the value I use a simple SQL query like this:
SELECT counter FROM companies WHERE company=0
then I store the value in a local int variable and then I increment it. Then I update the incremented value.
UPDATE companies ...
I need every single customer to have an individual value. My question is how can I prevent an error, data corruption or whatever if two or more users want to register at the same time? I've been reading about lock update but I'm not sure how to implement it on Visual Basic 2005 and I don't want to store scripts on SQL Server.
I'll appreciate your comments and help on this situation.

Hi,
I administering SQL server and one of or Db (size ~7 Gb) have a table with size 396 MB and 25 indexes created on this one. We working with this DB using Siebel Call center.
I have met a very strange situation: when I tried to get some data (using Siebel) my request take ~5 min. I run Profiler and catched this T-SQL statement which Siebel send to SQL server. After that, I run this T-SQL query using Query Analyser and found that Query Optimiser used wrong index. (clustered index) and try to compare every 470436 rows from the tables.
This is the statement. @P1, @P2, and @P3 just variable which siebel transfer to SQL server.
SELECT ........
FROM
dbo.S_EVT_ACT T1
LEFT OUTER JOIN dbo.S_CONTACT T2 ON T1.TARGET_PER_ID = T2.ROW_ID
WHERE
((T1.APPT_REPT_FLG != @P1 OR T1.APPT_REPT_FLG IS NULL) AND
(T1.TEMPLATE_FLG != @P2 OR T1.TEMPLATE_FLG IS NULL)) AND
(T1.SRA_DEFECT_ID = @P3)
But I found the very strange situation - when I manualy put the value '1-FRK' instead of @P3 - Query Optimizer used RIGHT index and I had a very good performance.
And addition when I tried to run the first Query on the same table but with the only 1000 rows the Query Optimiser choose right index.
Wat's on, wat happend with My Query Optimizer? Wy his decision so different from time to time?
Thank's a lot for any information about how to make Optimiser obedient.
