SQL Server Connection over WAN Link

I am planning
to setup a BlackBerry server and connect to a remote SQL Server over a
WAN link with 150+ms ping time. Is there a known tolerance for
SQL server connection latency? For example, I have been told by
RIM that ping time for Exchange should be around 35ms so if it is
higher, a BES should be placed next to the Exchange server. Any reply would be greatly appreciated.

There is no problem with slow connection :-)
You might get lots of waits in the SQL side (most likly there will be lots of
ASYNC_NETWORK_IO) which you can monitor using sys.dm_os_waiting_tasks and sys.dm_exec_requests. But if there is no disconnections then most small application will work OK

Issue while accessing a SQL Server table over OTG

Hi,
I have been learning oracle for about 1.5 years and am just starting to learn some OTG pieces. I am wondering about an issue. The issue is:
"We need help with an issue we are having while accessing a SQL Server table over OTG. We are getting the following error message in Oracle :
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC SQL Server Driver]Unicode conversion failed {HY000}
The column it is failing on is "-----------" in the view --------------- in the SQL Server database pointed to by the Oracle DB Link ------------------- thats created in the Oracle instances ---- and -----.
This was working before, but is now failing, we suspect its due to new multi-byte data being added to the base table in the above column."
I took out the details and added ---- instead. I am wondering your guys thoughts on fixing this issue and helping me learn along the way. Thanks

Hi Mike,
Thanks for the response, here are the details:
1. What is the character set of the Oracle RDBMS being used. What is returned by -
select * from nls_database_parameters;
NLS_CHARACTERSET
AL32UTF8
NLS_NCHAR_CHARACTERSET
UTF8
We get SQL_Latin1_General_CP1_C1_AS and 1252 as Collation Property and Code Page
The datatype of the column in question in SQL Server is nvarchar(100).
When I do a describe on the SQL Server view ( desc CK_DATA_FOR_OPL@------- ), I get the error below;
ERROR: object CK_DATA_FOR_OPL does not exist
Select * from CK_DATA_FOR_OPL@------ where rownum =1 does get me a row.
create table tmp_tab as
Select * from CK_DATA_FOR_OPL@----- where rownum =1;
desc tmp_tab shows the datatype of the said column in the table created in Oracle as NVARCHAR2(150).
Not sure why a column defined with size 100 in SQL Server should come across as 150 when seen over OTG. We see something similar in DB2 tables we access over OTG as well.

How do SQL server 2000 and Oracle linked?

Hi,
How do SQL server 2000 and Oracle linked?
Thanks in Advance
Baloch.

use the like to setup ODBC and datasource

and then create link server in sql server after you test conenction with oracle

Convert SQL Server ROW_NUMBER() OVER(PARTITION BY() Query to Access

Hi,
I am having trouble with converting this SQL Server query to Access. If anyone can give me help I would appreciate it.
SELECT B.AMOUNT_REQUESTED, B.INIT_OFF, B.MBR_NBM, B.STATUS, B.APPLICATION_NBR
FROM
SELECT AMOUNT_REQUESTED, INIT_OFF, MBR_NBM, STATUS, APPLICATION_NBR, ROW_NUMBER() OVER(PARTITION BY MBR_NBM ORDER BY MBR_NBM) RN
FROM LOAN_DATA
WHERE APPLICATION_DATE BETWEEN '20150420' AND '20150425'
) B
WHERE RN = 1
ORDER BY B.MBR_NBM

While there is no equivalent to ROW_NUMBER(), it appears that you are just wanting the first row of each group, and that CAN be accomplished in Access, but I do wonder why you would WANT to do that in Access if your data is stored in SQL Server. As
Tom indicated a Pass Through query object is likely your best bet -- or a View in SQL Server, then create a Linked Table object that points to it.
To get the first of each group ... which is essentially a TOP n, where n = 1 ... so .. the first thing you will want to indentify is a second field to use as a Key in order to define the "first" row you want in the group. In your SQL
statement, you are ordering my mbr_nbm, so the secondary sort is unknown -- likely predicable, but unknown with out knowledge of the schema ... so, I will provide samples by using APPLICATION_DATE as the sort key.
This one is the "first" of a series with the assumption that the one you want is the one with the "biggest"/"most recent" APPLICATION_DATE.
SELECT vLoanData.AMOUNT_REQUESTED, vLoanData.INIT_OFF, vLoanData.MBR_NBM, vLoanData.STATUS, vLoanData.APPLICATION_NBR
FROM LOAN_DATA As vLoanData
INNER JOIN
(SELECT MBR_NBM, Max(APPLICATION_DATE) As LastAppDate
FROM LOAN_DATA As vLast
GROUP BY MBR_NBM) As vLastApp ON vLoanData.MBR_NBM = vLastApp.MBR_NBM And vLoadData.APPLICATION_DATE = vLastApp.LastAppDate
Or ... the following is a TOP n query where n = 1.
SELECT vLoanData.AMOUNT_REQUESTED, vLoanData.INIT_OFF, vLoanData.MBR_NBM, vLoanData.STATUS, vLoanData.APPLICATION_NBR
FROM LOAN_DATA As vLoanData
WHERE (vLoanData.MBR_NBM & '|' & vLoanData.APPLICATION_DATE)
IN (SELECT TOP 1 (vCorrelated.MBR_NBM & '|' & vCorrelated.APPLICATION_DATE) As Key
FROM LOAN_DATA As vCorrelated
WHERE vCorrelated.MBR_NBM = vLoanData.MBR_NBM
ORDER BY vCorrelated.MBR_NBM, vCorrelated.APPLICATION_DATE DESC)
This second example is not going to win you any points with respect to speed, but is truly a closer model to the TOP N type thing you are doing in SQL Server.
Hope that helps!

Hi Tony,
Srry but No. We just installed the monthly updates.
I went back and found I had missed removing a patch. I missed the rollup for Windows Server 2003:
Event Type: Information
Event Source: NtServicePack
Event Category: None
Event ID: 4382

After I removed that is still didn't work but after about five minutes it started working.
I guess I ned to report that to MS after I research what might be changed to make the patch work.
Every time I get stuck and ask for help it seems to be just before I stumble on the solution.
Thanks for replying.
Well - maybe this will help someone else.
Thanks again for replying Tony

Why is my application name not showing up in the SQL Server connection properties?

If I understand correctly I should be able to have the application name from application.cfc show up in my SQL Server connection string (i.e. in the program_name column of sp_who2) if I go in to the DSN advanced settings and check "Application Name" under Client Settings.
However having done that I still don't see anything in the program name columns of the sp_who2 result set. Any ideas?
Thanks!

I drew my shape, then went to the GRADIENT panel and clicked in the default gradient box to apply the default white to black gradient. Normally you can click on either color to change it using the ways I described in my original post but those are not available to me. The only way I could add a color was to drag it from the SWATCHES panel into the gradient colors slider.
This means that I cannot make changes to colors directly in the gradient panel like before. I have to make changes to the individual colors but clicking on the color in the gradient slider then going to the COLOR panel and adjusting the color there. Or by dragging in a whole new color from the COLOR or SWATCHES panels. This is really killing my work flow.

Hi,
According to your post, an error occurred when you connect SQL Server in SharePoint.
We can do as follows:
1. Try to replace Integrated Security=SSPI with Integrated Security=True
2. Check whether there is <identity impersonate="true" /> under <system.web> tag in web.config.
Here are two articles for you to take a look at:

Can't create an MBO object using an SQL Server connection profile

Hi all,
I'm trying to create an MBO from an table using an SQL Server connection profile. The connection is fine but when i grag a table into Mobile Application Diagram in order to create an MBO i got the following exeption:
I´ve already configured the necessary jar (sqljdbc4.jar) in the following directories:

Hi Nuno,
I just wanted you to verify the path where you have pasted JAR file. As you mentioned
Path 1:
C:\Sybase\UnwiredPlatform\Servers\UnwiredServer\lib
but as per doc it should be under:
C:\Sybase\UnwiredPlatform\Servers\UnwiredServer\lib\3rdparty
Path 2:

First off, let me say that in the past (pre v9) when I've tried to use Windows logins with datasources, it never worked. But that doesn't mean that they finally got it working, just that I stopped trying.
What I was referring to in my post is that once you have CF installed, you need to go to the Windows Services screen, open each of the CF processes, click on the LOGIN tab, and change it from the default services login to be whatever WIndows login you have setup in Active Directory. Then restart CF so that it's process is now running under that login with its credentials. Then go to SQL Admin and setup that same login and give it access to the database you want to access. Then go to CF Datasource menu and setup the datasource as you did previously. If CF's support of Windows authentication for datasources does in fact now work, you should be in business.
If it doesn't work, then you'll need to do as I said earlier, and setup SQL logins for the CF servers to use, and then in the CF Datasource setup screens you would specify that login info in the same way that you would have given it the "sa" login info.

MDM-EP SQL/Server Connection Properties

I created a system in Enterprise Portal(EP) which I want to have connection properties to my local MDM Server which is my SQ/Server on my laptop.
Using the Connection Test, EP cannot connect. I've tried 'local', the SQL Server name (in my case USTEM05NB028939) and even the IP address of my machine... no can do! I do have an alias set up... I suspect that the Connection Properties for a local MDM server are illusive... does anyone have the protocol for a local SQL/Server connection?

Hi Tom
solution is as below
1) Please ensure EP is updated with latest Business Package of MDM 5.5 SP03.   Download the below Business Packages from www.SWDC.SAP.COM/Server using Service Market Place ID.
                   a. com.sap.mdm.tech.mdm4j.sda
                   b. com.sap.mdm.tech.connector.sda
                   c. BPMDMTECH.sca
                   d.BPMDMAPPL.sca
2) Ensure your "hosts" file (C:\winnt\system32\drivers\etc\hosts) on your laptop (MDM Server) has the IP address and hostname of the EP Server similarly update the same on EP server with MDM IP address and server details.
               ( Ex USTEM05NB028939   192.168.12.20) etc in the hosts file
3) Ensure all Java related patches of MDM are applied on EP which will enable WAS to identify the MDM IViews.
4) Go to MDM Console and check the Repository details of the repository that needs to integrate with EP. Identify the Repository Port that is running the Repository. Here usually if we have more than one repository in the MDM server we give repository ports like 1234,1235 etc but its imp to leave 5 ports for every repository example if the first repository is using 1234 as repository port then better user 1240 for the next repository.
5) Ensure you have accessed MDM Server Repository thru the Admin account of MDM Server from EP.
6) Also change the Windows Authentication mode of SQL Server to Administrator Mode for SA in SQL Server.
7) Also kindly mention the 'MDM 5.5 Host Server' as 'USTEM05NB028939' (If USTEM05NB028939 your MDM Server name) rather than Local on your EP.

FXO traffic is going over Wan link after enabling QoS

Hi,
We have CCM 5.0,2811 voice gateway,1 4FXO and 1 g.shdsl card on it. 4 Telco lines are on 4FXO card.CCM is at the other side of g.shdsl line.Topology like that,
2811 ---------------- CCM
4fxo g.shdsl
When a call receives from FXO port, system is working normally without QoS. When we enable QoS traffic,traffic is going over wan link then return again.Because of that,delays and timeouts occuring.Router's config is at the attachment. Please Help!
Thank you

Check your H323 gateway config in CCM to be sure the Media Termination Point Required box is unchecked. Using MTP forces the call to terminate on the closest MTP resource which is likely at your CCM site.
Please rate helpful posts.

30EA2 - Feedback on Microsoft SQL Server connectivity

I think Oracle SQL Developer is great! But I also think it could be better.
I believe Microsoft SQL Server connectivity in SQL Developer could/should be stronger/simpler if, for no other reason, than the simpler it is the more likely there will be converts.
In Help -> Check for Updates ... I'd propose an Update Centre something like External DB connectivity or Third Party DB connectivity. In other words, make it obvious.
Failing that, or perhaps in addition, instead of calling it JTDS JDBC Driver 11.1.1.58.17 why not Microsoft SQL Server connectivity, with JTDS ... in the description?
And then, this is the big one, make installing the JTDS JDBC driver update actually enable connectivity to MS SQL Server.
Initially trying to connect to a MS SQL DB, having installed no updates, I get the error:
An error was encountered performing the requested operation:
Driver class not found.
Verify the Driver location
Vendor code 0
SQL Developer "knows" I'm trying to connect to a MS SQL DB, so why not a slightly more helpful error?
After installing the JTDS JDBC Driver I do get a slightly more helpful error (in that it contains key words I can Google):
An error was encountered performing the requested operation:
I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.
Vendor Code 0
Connectivity only begins to work after I do this/these additional step/s:
Copy the file 'jtds-1.2.2-dist\x86\SSO\ntlmauth.dll' from the unzipped JTDS --> <SQL Developer Home>\jdk\jre\bin. Then restart SQL Developer.
With thanks to:
http://www.dbforums.com/microsoft-sql-server/1612362-java-sql-sqlexception-i-o-error-sso-failed-native-sspi-library-not-loaded.html#post6368137
Then, and only then, it works just fine.
With thanks for Oracle SQL Developer,

Well to be honest there is no good reason to use access to connect to PeopleSoft But we see the same problem in a totally unrelated program called RFGEN or even Crystal Reports through odbc. The Problem is I did not want to field all the questions about RFGEN.(what it is, how it works, must be something wrong with it etc...) I would have thought that someone has connected and used Access. RFGEN is a third scanning System that works with our existing system on SQL Server and we want to keep it and use it with the PeopleSoft.

SQL Server Connection Issue

I've tried going through the steps to resolve the issue, but I am still coming up blank. The part that I am not understanding is the, "A non-recoverable error occurred during a database lookup." part.
Is this a security problem? I can establish an ODBC connection to the server as well as connect and query through visual studio, however when trying to run it through one of our custom programs, it throws this error message.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider:
TCP Provider, error: 0 - A non-recoverable error occurred during a database lookup.)

There are many reasons of SQL server connectivity issue. Refer checklist to find out the real cause of connectivity issue.
1. Check SQL services are running
2. Check SQL Browser service is running
3. Check remote connections are enabled
4. Network connectivity between database & application servers by TRACERT command
5. Check TCP/IP protocol enabled at SQL server
6. Check talent connectivity – telnet <IP address> <port no on SQL server running>
7. Check UDP port 1434 is open or not on SQL Server
8. Check firewall is running or not Check
9. If firewall running, SQL Server & UDP port must be added in exception in firewall
10. Run SQL Discovery report on machine SQL server installed, to check you are using correct instance name to connect( default \named) -http://mssqlfun.com/2013/02/26/sql-server-discovery-report/

SQL Server Connection errors

I am receiving the following error when attempting to open a SQL Server connection in a C# console application: "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was
not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) SQL Error"
1) my coworker built the project on his machine (same code) and the project works - no errors
2) I used the identical connectionstring (same code for that matter) in a server app vs. console app - no errors
3) I built the connection using project properties/settings (Properties.Settings.Default) - test the connection on the Connection Properties window - "Test connection succeeded." Use the connection in my project to open a connection -
receive error.
4) ping to server - no errors
5) I used PL/SQL developer to connect to server using same connection information - no errors
6) I installed Visual Studio 2013, built the project - receive error
I am stuck at this point. Can anyone help?
Thank-you,
Barbara Velasco

Hi Barbara,
Firstly, please make sure that the SQL Server Services are running. Other reasons could be incorrect connection string, firewall block the connection and so on. Please refer to the following article to troubleshoot this issue:

In addition, here are some good articles regarding troubleshoot SQL Server connectivity:
