Hi Y'all,
When i alter 1 single value in my sql server 2000 sometimes i get following error:

After clicking away:
2)CANNOT START MORE TRANSACTION ON THIS SESSION
Maybe someone can help me out on this?
Thanks!
Hi,
I am using ADO in my application to connect and retrieve data from Microsoft SQL Server 2000 SP4. When I start my application, it establishes connection to the server successfully and I am able to retrieve data from the server. here is my test scenario:
1. unplug the network cable from the client machine and put the cable back in after some time. I disconnect from the database in my code when the client machine disconnects from the network
2. Once the client machine comes back on the network, I try to reconnect and retrieve data from the sql server but I get the following error message when I try to execute a sql command:
[Microsoft][ODBC SQL Server Driver]Communication Link failure
This problem occurs only with Window XP SP2. With XP SP1 it works fine. It seems to be problem on the client side as with Windows XP SP1 I do not get this error message at all.
Here are the various details:
1. The firewall is off on the client workstation.
2. the connection string is:
driver={SQL Server};server=AA;uid=BB;pwd=CC;database=DD
where AA = DNS name of server machine where sql server is running.
BB = user name
CC = password
DD= database name
3. The client is remote to the server.
4. I can ping the server machine when the client machine reconnects to the network.
5. I can still telnet the server when the client machine reconnects to the network.
6. client database provider is MDAC odbc.
7. the client and server machines are in the same domain.
8. Shared memory and TCPIP protocols are enabled and TCP is at the top of the list.
9. No alias is being used.
10. Viris scan is not installed.
11. force encriptioned is NOT checked.
Please reply.
We are running SQL 2000 sp4, only one user database (SAP) the database is 63 GB.
The ldf files were trashed so I went to tape to restore.
We are using veritas backup exec 9.1 sp4. Veritas is on the same server. I can restore the master db and the msdb fine. However when we attempt to restore the DEV db it runs for 2 hours and then fails with a communication error from veritas.
When we restore the master the DEV db comes up suspect as there are no files for it to attach to) so we cannot attach to it to restore, so I have deleted it and attempted to restore - same communication error. I have recreated a db named DEV with the mdf etc created to the size needed plus some to be sure, no good same behavior (behavior described below).
The job starts and it creates all the folders for the database (there are 1 MDF, 5 NDF, and 4 LDF files each in its own folder). Then it begins to create teh individual files it gets ~half way through at about an hour-hour and fifteen. During this time there are a large number of writes being performed by SQL (I assume it is creating the structures). Then it switches over to reading from tape a large number of read by beengine for another 45-1.5 hours then the job fails with the error unable to communicate with the device. I ahve noticed that once it starts reading from tape the db is gone from enterprise manager, and the mdf etc. files that were being created are now gone.
Help this has gone on for three days!!!
Hi Folks,
This is regarding the intermittent failure of communication between the application server and database server in one of our customer environment. Application error as well as SQL error log shows "General Network Error","Communication Link Failure". Please find below the server configuration
Application Server OS: Win 2003 server + Service Pack1, Standard Edition
Database Server OS: Win 2003 server + Service Pack1, MS SQL Server 2000 + SP4
We have checked the Client/Server Network utility associated with SQL Server and found TCP/IP protocol is used in communication neither than Named Pipes. DSN is used. We have also followed and implemented as per one KB article which mentioned Win 2003 server's feature of preventing Denial of Service attacks (Chance may be there to prevent the valid login packets).We made the registry changes and disabled this feature. A scheduled job which updates the database happens every morning. Also backup was done using a backup utility which needs the exclusive access to DB. So we have asked the customer to use enterprise manager for back up the DB instead of using the other utility to backup. If any one have experienced the same issue, please let me know.
Thanks,
Pranav.
Hello
TestMachine1 runs SQL2005 SP2 and has as linked server myRemoteServer (SQL2000) server. I run an stored procedure in TestMachine1 which inserts about 20,000 rows to a table in myRemoteServer and brings back a similar quantity of rows. This stored procedures take about 1.5min to complete, but no error appears.
When running the same stored procedure in TestMachine2 (also SQL2005SP2), the following error appears after about 1 minute of execution (not the exact text):
SQLNCli. TCP Provider: network name is no longer available - communication link failure.
Please note that this stored procedure worked before on TestMachine2 (but with less than 10,000 rows) and that connectivity is proven among TestMachine1 and myRemoteServer, since I can execute "select * from synonym_MyRemoteTable" with no problems at all in the TestMachine2's Management Studio.
TestMachine1 and TestMachine2 have Windows XP Professional SP2; myRemoteServer has Windows 2003 and SQL Server 2000 SP4.
Can you please help me to avoid this error?
Hi all,
I am wondering if you guys have any experience with failing Stored Procedures running inside a SSIS package with the following error:

Sometime it fails when gets called through a job and sometimes even when a package is open in a design mode. The actual Stored Procedure NEVER fails if called in SQL Server Management Studio.
Any ideas or suggestions will be very helpful and appreciated

Hi all,I am trying to setup a VB.Net development environment on my desktop for one of the application which was already in the production for couple of years (some unknown contractor(s) developed and maintained it so far). The application works fine on the web.Visual Studio 2005, .Net 2.0, SQL 2000, SQL Server 2005 were installed on my desktop. When I try to build the entire application/solution in the debug mode (i.e., with http://localhost/), build succeeds and I could get to the login.aspx. When I try to login, I am getting an error in the Visual Studio at the following code;connection = New SqlConnection(connectionString)
connection.Open()
saying "Communication with the underlying transaction manager has failed", "System.Transactions.TransactionManagerCommunicationException was unhandled by user code". And the web browser displays the following error "Error HRESULT E_FAIL has been returned from a call to a COM component". When I try to connect the SQL Server 2005 with the same ConnectionString attributes by going to Tools>Connect to Database, it works fine. But, through application connection.Open() giving above errors. I have set the MSDTC properties (i.e., under Component Services>MyComputer Properties>Security Configuration) as below:-Enabled Network DTC Access, Allow Remote Clients, Allow Remote Administration, Allow Inbound, Allow Outbound, No Authentication required - selected, Enabled XA Transactions...& DTC Logon Account is "NT AUTHORITYNetworkService".Please help.Thanks in advance,Chandra
When running the etl I'm getting the error: <SSIS Task>: Shared Memory Provider: Timeout error [258] ; followed by the message "Communication link failure".
What is special about this message that it happens on a SQL Execute task (random task) and the Timeout is after 2 minutes.
When executing the packages separatly it is working fine. The SQL Tasks that are failing are also quit heavy, but reasonable and takes between >2min and 10 - 15 min. Statements are stored procedures that puts an index on 3 mil. records or update statements,...
I had a look to all my (SSIS-etl)Â timeouts and they have the default value 0, the "remote query timeout" of the server is set to 10 minutes. According to me, these are the only one that exists?
There are 2instances on the server each instance has 24GB allocated, the server has 64 in total. Also when the etl runs (that results in an error) no other etl is running on the 2 instances. I'm working with the oledb sql server native client11.0 provider : SQLNCLI11.1.
we have our cubes in Server A and SQL DB resides on Server B (we are on SQL 2014), from last couple of days are cube started failing due to below error:
OLE DB or ODBC error: Protocol error in TDS stream; HY000; Protocol error in TDS stream; HY000; Protocol error in TDS stream; HY000; Communication link failure; 08S01; TCP Provider: An existing connection was forcibly closed by the remote host.
; 08S01
I have been going through some blogs to understand the error but don't find any specific yet.
Hi,
I have created vb6 app to connect to sql server 2000 db, and now i have a new requirement: to publish this app on web, but I should use an exising vb6 application that includes all buisness logic and all communication with database: quieries, stored procedures, etc.
To implement this, i create a client :HTML interface and server: asp file that receives an input from client and calls vb6 functions with parameters he received from client. My question is: how can i call from asp application a vb6 application?
I have a database where it will be simple to calculate needed data. Specifically I need to calculate the sum of several columns based on a number of WHERE constraints. I can write the SQL statements - up to a point. The point is the transition to VB. For a simple example
Select sum(Costs) from Research where (Code = 01213).
Now somewhere I have floatiing around in the machine I have my answer but how do I get the SQL results as a variable I can equate to my Visual Basic variable Total_Research_Costs?
Please also let me know if I have won the stupid question of the month?
Thanks for your help.

We are using SQL Server 7.0 with Windows NT4 SP4, IIS and ASP
We are not using any complex joins or view updation. We are using ADODB connection variable with an application scope to establish the connection. When we try to use the connection object to open a Recordset, this error occured. We colsed the connection and destroyed the ApplicationScope Connection object and re-created the object with out any success.
I get ODBC Error 823 when I try to access data from Crystal reports and I/O error, communication link failure...from query analyzer. But the weird thing is it is on and off. If I keep keep clicking 4 times in a row it happens 5 time or 7th time. It is alo only on one of the big tables. They are all stored on same primary filegroup?
Any ideas on what this might be? When I checked BOL it said disk error. The network team doesn't seem to agree. How can I make sure it is hardware or software problem?

View 1 Replies View RelatedI am trying to setup an alert system for our new application. Idea is to create triggers on the tables that we need updates about. When a table changes trigger will be fired and that will send a change data message to a service on a
different sql server. That service will process the message and create an event in the notification services database. Notification service will later send an email or sms etc depeding on what is required.
Currently i got the message exchange working between two service in the same database. Now I am working on exchanging message between two SQL Servers with no luck. Can anyone please post an article on how to setup communications between two services on different servers.
I did try to expose service broker as an endpoint and create a route on the other server to call it? (This don't work)
Thanks,

Hi...
We had a setup that used to work up until about a month ago, and I'm just getting around to investigating it. A previously functioning Service Broker app exchanging messages between 2 boxes in a dev/qa environment stopped delivering messages.
Both endpoints are set up to use AUTHENTICATION=WINDOWS and have connect granted to public on both.
The sender side has all the messages piling up in the sys.transmission_queue. When I profile the exchanges, I see initiator -> target connection then the target trace gets
10054(An existing connection was forcibly closed by the remote host.)
and the initiator trace gets
Connection handshake failed. An OS call failed: (80090350) 0x80090350(The system detected a possible attempt to compromise security. Please ensure that you can contact the
server that authenticated you.). State 66.
I've checked that the login that's used to run the target Sql Server instance is in the security list for the initiator instance. I've checked that I can log into the initiator instance with the creds for that account. Both machines can see the domain controller.
I've googled on the "forcibly closed" message in the target trace but all I've found so far says that it's either
1) mismatched security
2) no connect on the endpoints
3) expired certificates.
None of which appear to apply here. Haven't found any message mixing "forcibly closed" with the latter message.
Any ideas?
Thanks

Hai,
Iam using VC++ application to connect remote database(MSSQL) through network.
Everything works fine, if the network connection is active. If the network breaks and resumes, the application throws "Communication Link Failure" and do not get connected even after the network is resumed.
Client :
* Windows 2000 Professional
* MDAC 2.5
* VC++, using framework- CRecordset to access database
* PEER to PEER network configuration
* DSN through ODBC
Server :
* Windows 2000 Professional
* MDAC 2.8
* MSSQL Server
how to resume the database connection ??
Any one help me????
Thanks in advance,
We replicate from London to New York and Hong Kong. The New York replication is working fine but everytime we try the Hong Kong replication it starts doing it but when it gets to the bulk copying stage it'll still keep going but on a random table will suddenly fail with a communication link failure message ?? It used to do this and because it keeps trying it used to eventually succeed but recently it never succeeds ?? It keeps trying but we end up having to stop it as it just doesn't succeed anymore ?? Our link to Hong Kong appears fine, we can ping and PC Duo into their servers.
Any ideas would be greatly appreciated as we can't think what it may be ??
thanks

We have been seeing random inexplicable communication link failures when communicating with a Win2K SQL server for a while now. After a very detailed analysis of the various causes of the problem (network, name lookups, etc.), we've narrowed it down to possibly the ODBC driver. We are using TCP/IP.
I've stuck a packet sniffer on the connection between the SQL server and the client and in almost all cases, the connection suddenly terminates with the client sending a TCP reset to the server.
Looking at the packet traces further, it seems like in about 60% of the cases, there is period of activity on the TCP connection, then some inactivity during which there is a constant stream of TCP keepalives between the client and server and then suddenly the client resets the TCP connection.
Now, we can usually correlate this TCP reset to some new activity initiated on the client application, so could this be related to connection pooling in the ODBC? Thats the only inference I can obtain.
We are running Win2K SP3a on the server.
Any ideas on what else to look for or how to debug this further? I have 10GB of packet traces and can provide more details on the connection traces if necessary. The problem also is that we have ~100 clients constantly communicating with the SQL server and we will see anywhere from 10-20 random CLFs in a day.
I've searched the archives extensively and this does seem to be a problem for many people, but a few of them seem to have had genuine network problems and we've pretty much ruled that out since there are other simultaneous TCP connections between the client and the server and they seem to be okay.
Thanks,

Hi Guys,
I am using C++ (Ver 6) that connects to a SQL Server 7 DB using ODBC drivers. The apps connects to the database in the start and listens to the users requests and replies with the required data.
The apps is working fine, but once in a while it looses connection and gives "Communication link failure" message.
I just restart the apps and it is able to reconnect and perform as normal without any problems.
I am not able to find the reason as this behaviour as its very much unpredictable!
The error is returned by SQLExecDirect() function.
The question is, since I still have the Connection Handle, is it possible to just reconnect to the database re-using the same handle ? or do I have any other choices ?
Thanks in advance.

Okay-- if anyone can solve this they are truly the SQL genius! We are getting this error when we run a VB program that we use to access an SQL database on a server across our network on a workstation. In fact we get this same error when we even run the program on the server where the SQL database is running or on any of our workstations. Here is the error message:
08501:[Micorsoft][odbc sql server driver] communications link failure
Now the odd thing is that many other functions in the workstation application work fine and retrieve data from SQL but certain data requests by the workstation application fail with the above error message and we get this message consistently. Even though it appears that different workstations running the identical Vb application will get this error consistently but in different locations when running the application. We were running SQL 6.5 on an old server, with the workstation application for literally years without any problems. We also decided to upgrade to a new server, installed server 2000 operating system and the latest version of SQl -- moved all the databases pointed the workstations odbc at this new server and get exactly the same error in the same location in the workstation applications. The programmer that wrote the application and designed the database in SQL can't find the problem and a number of other computer "experts" also could not find the error. We did add a new linksys DSL router/firewall but everything kept working after this installation for several weeks so I don't know if this is the problem on the network. THe programmer also noted that he had problems using terminal services on our network to connect to his office computer and decided that there must be some network issues that are causing the ODBC communicaitions to fail and also terminal services to fail-- or of course they may be unrelated. Has anyone ever seen this ODBC communication error in their travels through SQL implementations? Any help will be greatly appreciated. If we can't fix this we will have to abandon a software application that has been used for over five years and just too complex to rewrite.

Hi, when I try to activate my address book, i get the error "There is no pool available for this operation. Exit the wizard. (Error Code: 0xc3EC78D9)".
I have verified my mmc shows that LCS is at SP1, it is activated, and
functioning properly (users able to interact via OC2005). It is locally
installed on the standard edition server.
SQL 2005 Standard x64 Service Pack 2
Windows 2003 R2 X64 service pack 2
The principle, partner and witnesss have two NICs each (NIC1 and NIC2). I want them to communicate in NIC2 for sending logs and establishing quorum. This will happen in their own private network (say 192.168.1.0/24). The NIC1 in each server will be available for client communication. The domain and clients are in the network (say 10.1.1.0/24).
I am using the same domain account as SQL server service account in all three servers.
How can I do this?
Thanks
Problem: We have intermittent failures of SQL Server jobs with the following error -
TCP Provider: The specified network name is no longer available. [SQLSTATE 08S01]
Communication link failure [SQLSTATE 08S01]
Types of job steps failing: DBCC Checkdb, LiteSpeed backups, re-indexing sql in stored procs, home-grown database update stored procs. These types of job steps are failing on 3 different servers in a 4-way active cluster although all 4 servers have the same type of job steps. No steps involved attempt cross-server processes, job only uses its own server and SAN.
Environment: 4-way active IA64bit cluster Windows 2003 datacenter running SQL2005 RTM. All 4 nodes attached to EMC Clarion SAN.
What we have already looked at: No additonal messages in event viewers. SQL Agent additional logging shows same error. Network services has monitored and sees nothing. Network services is current on firmware upgrades (just applied last batch 2 weeks ago) and still got 2 more errors after the upgrades. I've seen other postings (with no solutions) where people have same error with SQL2000 through SQL2005 SP2, so i don't believe SP2 will help this.

My program connected to SqlServer when it started, the state of the connectionPtr was adoStateOpen.Then I disable the network card and enable it immeditately, the errors happened when I executed the sql query probably because of connectionPtr was invalid,but the state of connectionPtr was always adoStateOpen.
