Unexpected Error With JDBC SQL Server 2000 Connectivity
Sep 3, 2007Hi,
We are running one shopping site for our organisation, which includes Tomcat 5.0.28 , IIS & SQL Server 2000 SP3 hosted on platform Microsoft Windows Server 2003 Enterprise Ed. , we are running jsp pages server side and site is hosted on internet,
but it is observed that after every 1/2 days , page will throw following exception, and site get blocked.
javax.servlet.ServletException: Network error IOException: No buffer space available (maximum connections reached?) : connect
Can anybody help please?
I am beginner with JDBC - SQL Server Connectivity ,
I am giving our configuration details:
Driver Used - Microsoft SQL Server Driver 2000 SP3
Protocol Used - TCP/IP which open socket connection on default port 1433
Authentication - Mix Mode Authetication ( using sa account login)
Even setting done within LOCAL instance running on server to allow max. connections i.e 32767
My observation is that some kind of virus threat may causing this error, because if server will be rebooted, we doesn't
get any error and everything works fine.
Waiting for your suggestions and advise.
Thanks a lot.

Mandar Velankar

JDBC Connectivity Problem
Nov 9, 2006An application on our sql 2005, x64, server is trying to connecto to our HP 3000 using JDBC (from MiniiSoft). The applicaiton fails.
Are than any administrative tools from Microsoft that I can use to see if the JDBC connection is good? (We are new users of th app and it is possible that we have misconfigured the app but be want to check that JDBC is working as a first step.) We use jre 1.4.2_11
TIA,
barkingdog
P.S. I have heard about a Microsoft JDBC product. We haven't tested it and don't know if it can talk to an HP 3000 (which uses a MiniSoft listener)

MS JDBC Driver Incompatibility With JDBC 3.0 Specs
Aug 8, 2006Hi all,
We've just stumbled on a 1.0 version incompatibility with the JDBC specs.
Problem: A table with SMALLINT column. According to JDBC specs version 3.0
(p.B-179) and 4.0 (p.221)), the value should be converted to Integer type.
Unfortunatelly we get a Short object :(
Now, I remember, this case was also affecting old JSQLConnect driver from
DataDirect. Could that problem sneak to new MS driver too?
Please let me know any resolution to this problem if exists.
The issue has not been fixed in CTP 1.1 version. Any ideas if it can be fixed??
Cheers,
Piotr
2000 JDBC Vs 2005 JDBC
Mar 12, 2008
I've got an import app written in Java. One table I'm importing from contains 22 million records. When I run the app in a 2000 environment, I have my max heap set at 512, and the table gets imported. When I run in a 2005 environment, I have to change the max heap to 1152 or it will error out with a similiar error:
com.microsoft.sqlserver.jdbc.SQLServerException: The system is out of memory. Use server side cursors for large result sets:Java heap space. Result set size:854,269,999. JVM total memory size:1,065,484,288. (<--this is with max heap at 1024)
what is the difference between the 2000 and 2005 JDBC that I have to set max heap in one and not the other?

Jun 21, 2001I had SQL Server working without a problem on my laptop until I changed the identification name of my laptop to make it more recognisable when I connect to a LAN. However, since I've changed my laptops name, my local SQL Server service wont run and I cant connect to my local databases. I can connect to remote SQL Servers though. If I change my laptops name back to what it was before, it still doesnt work. This has happened in the past and the only way I could solve the problem then was to uninstall SQL Server 7, remove all registry keys referring to it then reinstall it. I dont want to do all that again so....HELP!!!???! I'd really appreciate any help anyone could give me. Please email me at adrianmhills@hotmail.com

SQL Server Connectivity And Security
Feb 2, 2008Couple of questions for the SQL Server Guru's out there.
SQLServer 2005
Web Hosting Provider
Ok I am developing a Web application in ASP.NET with AJAX, etc. etc. It will be some time before it is ready to roll out. As a mockup I created the same application in Microsoft Access and Visual Basic (VS 2008), which I can link the tables to the hosting provider on the internet. Works very well and speed is very acceptable.
My question is, is how secure is the data that is moving from the local application to SQLServer 2005 with the web hosting provider ? Is there anything that I can do to increase security ?
Thanks, any thoughts ?
SQL Server Connectivity Error...
Mar 3, 2008Hello All -
I am using SQL server 2005 sp1 to work with my applications... and i am using ODBC connection to communicate with SQL serrver...
The connectivity has been working fine for more than a 6 months now .... and suddenly it thows an error ...
"General network error. Check your network documentation.ConnectionRead (recv())."
There about 10 applications accessing SQL server... and all the applications throws this same error...
I intially thought it migjht be bacuase some applications are over utilizing the SQL connection and not closing them properly... but i noticed the connection opened in the Activity monitor are the same as it supposed to be ... no extra unwanted connection opened...
I also noticed that SQLserver.exe process is utilizing almost all the RAM memory and trying to allocate more page memory.... so i restarted the SQL sever service and that reinstated all the connectivity properly....
in couple of days .... the memory utilization again reached the max and this problem started again and i had to restart the SQL server again... and this problem happens every 2 days...
I know SQL server is using up those memory for caching purpose which is normal... but Y would this cause the connectivity to fail...
Is it a problem in SQL server 2005 SP1 ... shd i upgrade it to SP2?
If some of my application is causing this how would i narrow it down to that application and pin point on that particular one?
The thrown error does not have much information for it to guide me in a direction for debugging...
Please can any one help me tro this problem?

Check Connectivity Sql Server
Jun 6, 2007Hello all, I am hoping this is the correct place for this. I have an application that depends on an active connection to Sql Server Express 2005. I am looking for a way is any to check for the existance ofthe server I defined and wether it is online or not. I know I can just catch the error on connection but it takes a bit and I have customers trying to cancel it before it's finished because they think it's locked up. I would like a quick way to check without trying to create a connection if it's online, then if it is, proceed, if not, let the customer know. I was hoping for something like a database server ping of sorts.
Thank you,
Jim
Do I Need To Create A Domain To Get Connectivity To A Report Server Database On A Remote SQL Server Instance?
Oct 23, 2007I'm setting up a simple SSRS implementation for a non-profit organization, using two servers hosted at a data center. The first server has SQL Server Standard Edition and Reporting Services installed. I've designed and deployed a number of useful reports on this server.
I was hoping to isolate this first server by installing IIS and SSRS on the second server, have users browse from the Internet to that second server (over SSL, of course), and have all reports served up from databases (and, presumably, the report server database) on the first server.
During the installation of SSRS on the second server, however, I'm being prompted to specify the service account. According to the help text:
"Reporting Services. Service accounts are used to configure a report server database connection. Choose a domain user account if you want to connect to a report server database on a remote SQL Server instance. If you are using a local report server database, you can use a domain user account or Local System to run the service."
I believe I want to configure SSRS to connect to a report server database on a remote SQL Server instance; therefore, it appears that I need to enter a domain user account. The only problem is, neither server belongs to a domain; they are members of a simple two-server workgroup.
Does SSRS, configured to connect to a report server database on a remote SQL Server instance, require a domain? Does what I'm hoping to accomplish require a domain? Creating a two-server domain seems like overkill for this implementation, doesn't it?
I appreciate any comments and suggestions. Thanks!

When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

Here are the points to be noted.
1. The queries work when executed individually.
2. The client can PING the server.
3. I tired changing the default network libraries to 'Named Pipes' but this also returns
the following error

SQL Server 2005 Remote Connectivity
Feb 13, 2007I am an application developer with an existing system developer in SQL Server 2005 Express and Visual Studio 2005.
I have installed the system I wrote at a physician's office, and it is working fine on a local computer utilizing XP operating system.
There is a requirement to allow other terminals to connect to this XP terminal to execute the application, so I am exploring possibilities for connecting remotely from the other computers in the physician's office.
I am running Virtual Machine for my client computer.
I modified SQL Server 2005 on my main computer. I enabled both TCP/IP and Named pipes in the SQL Server Surface Area Configuration utility. I also set SQL Server Browser to start automatically.
The local application is successfully connecting with the following connectionstring: Data Source=localhostsqlexpress;Initial Catalog=MedicalDB;Persist Security Info=True;User ID=sa;Password=thepassword
I realize that I would have to substitute the server name for localhost before I could connect from the application, but I wanted to first "connect" to the database from my second machine successfully before I began trying to connect from my application. I can Ping the pc that is running sql server express, I am able to "telnet" my pc that is running SQL Server Express.
Both my computers are in the same workgroup and there is no domain.
There are no aliases in my configuration, and there is no encryption on the server.
Ther error message I recieve is:
Cannot connect to DDD
An error has occurred while attempting connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under default settings SQL Server does not allow remote connections.
