Hi,
I have Oracle 9i. Oracle listener is aborting by itself after every few minutes giving TNSLSNR.exe failed. While listener is running I can do all the activity on the database.
Please let me know if there is any solution.
Thanks in Advance.

I have a query that retrieves a single record from searching on two tables.
The statement goes like this...
select sum(amount) from Table1 A union Table2 B on a.id = b.id
where date < ### and date > #### and account = ###
As people are running a particular report, this statement is executed time and
time again to pull up the numbers necesarry for the report. When the report gets slow, I can speed it up by updating the statistics. My concern is that I'm having to update the statistcs every hour; otherwise, the query becomes slow. I have noticed that users are inserting data while users are running the report on one of the tables listed above. I'm sure that's making it become more fragmented and ultimately slowing down the query.
Do you have any suggestion on how I can make the union of these two tables faster? Or is there anything I could do to speed the query besides creating clusted indexes?
Any help would be appreciated....thank you
Hi Everybody:
We have a table which needs to be updated 2 million times per day. It hosts all real time transaction. There are 200K records in this table. Would you please to share your experience with me about how to protect/save such table in SQL 2000 from any possible damage?
We plan to use point-in-time backup (every 5 minutes). It still takes at half an hour to recover the whole database. Any new technology from Microsoft or SQL 2000 you can recommend?
Thank you very much.

Can any one recommend an approach for identifying the frequently accessed tables and files in a SQL/Server application? Particularly, if the database is stored on raw partitions instead of FAT or NTFS. Thanks.

What is a Yak? 07May2007
Hey guys. I need a little help once again, here's the problem:
We are using an attendance system software that adds records in an Access 97 table whenever someone logs in or out of the room (Yes, it's old and I hate it, but it came with the hardware).
So we plan to create a program that lets admins check those login/logout data in an SQL Server 2005 database using a Visual Basic as the frontend.
Our only problem is, how do we transfer data from the Access 97 tables to our SQL tables *everytime* it gets updated? We don't need every detail the Access97 table has (it has IDNo, CardNo, Time, Location, plus other useless stuff). We just need to extract the IDNo(int) and Location(varchar) field(we'll just use getdate() for the Time since the update is done in realtime anyway).
So in a way, we are trying to find out a way to technically sync both tables, just like Database Mirroring style.
Any suggestions?
Hi,
In a project with SQL Servcer 2005 the customer is interested to save (archive) content of a table frequently. They want to have possibility to restore the table content as before. I have suggested to export the table every day to a text file and save the file in Visual source safe. If they need there will be possibility to import the text file later. Now I wonder, is there any other way to do archiving of the table content in SQL Server 2005?
Best regards

Hi guys,
I faced problem related to Locking and Isolation Level on Table(s).
My problems is there r some tables which r frequently updated, and I also want to fire select query over those tables every 1 seconds and want to get only committed records.
In current scenario we start transactions with ReadCommitted Lock for updating records. But in this scenario I can€™t get select query result because of some of recourses r used by transactions so after some time it gives Deadlock error.
So I want solution like both operation run simultaneously and get only committed records at a time of transaction running
Please help me for solving my problem.

I'm working on databases where statistics of some indexes (tables) are changing too frequently. Once I update them manually, one minute after they get 10-20% change, and five minutes after they get over 100% change. Tables get updated very frequently (multiple times in a second).
When I run a query to read from sys.stats, sys.dm_db_stats_properties and other dynamic views, I see that they were last updated when I did it manually, but the change rate overpassed the 500+20% (tables have multiples of 10K rows). Auto create and update statistics are set to true on all databases, and I don't know why sql server does not do that automatically.

View 1 Replies View RelatedI am new to Service Broker and Query Notification. I've used Books Online and the other help files to successfully create a class to subscribe and listen for mods to a table on a SqlServer 2005 (SP1 applied) server. My prototype worked exactly as expected.
However, when I put my code into production, the listener was calling my NotifyEvent() callback repeatedly, and without any changes being made to the table! Of course, I'd tested with a simple two column table and implemented with a more complex multi-column one. After some experimentation I discovered that the problem occured when the SELECT statement refrenced a "blob" column.
That is, the CREATE TABLE command included a column:
[Data] [varbinary] (max) NULL
and the SELECT statement looked like:
private const string _select = "SELECT [Role_s], [User_s], [DataType], [Project_s], [DataName], [tag], [Data_s], [ScopeType], [ScopeOwner], [Data1], [Data2], [Data3], [Data4], [IsProject], [Data] FROM [ovs].[OVS_AppData_tbl] WHERE DataType='SchedTask'";
SqlServer called my NotifyEvent() continuously. If I removed the [Data] column from the select, then the code worked as I had tested. I also tried this on another table (fewer columns) that also had a [Data] defined similarly, and again the continuous notifications came. I've got a workaround because I also calculate a hash on the [Data] column, and I can "watch" the hash instead of the underlying [Data].
Oh, when I ask SSMS to script the table with the [Data] column it gives me:
[Data] [image] NULL
This may (or may) be relevant (vs. varbinary).

View 4 Replies View RelatedHi,
I'm new to this SQL thing, and I inherited a DB that has a job that runs every two hours 24/7. Normally the process takes about 5 minutes to complete, but on occasion it just doesn't finish. In those cases, it cannot run at the next two hour cycle. If this happens on a Friday evening, it doesn't get noticed until Monday morning. That is a Bad Thing (tm).
Someone told me to create a second job that would run 45 minutes behind the first and automatically stop the first job if it hadn't terminated on it's own. My problem is I cannot find anywhere how to do this. I have found how to start other jobs, but not stop them.
Thanks in advance!

It appears that our web server (IIS 4) stopped responding after running
some BCP jobs. Anyone know why BCP would interfere with IIS.
SQL and IIS are on the same server. Anyone had problems with IIS/SQL getting along?
After the problem showed up, SQL responds fine in ISQLw, but the Web service goes out to lunch.
I scheduled jobs to take backups, but i found out that sqlserver agent is stopping by itself, what could be the solution for this problem.
Thanks in advance

I then cleared the generated data and selectedDesign Query in Editor. I then picked both tables in the 'Add Table' window and picked 'Add'. This produced two windows and I made the links I needed and clicked OK. This generated the SQL I wanted and it works great! But when I close the SQL Express and then re-open it the SQL does not work!

View 1 Replies View RelatedI have set up a couple of servers in a SQL 2012 AlwaysOn Availability Group (non FCI). I have also configured a Listener which enables SQL clients to connect to the server currently servicing the database, as expected.
I would also like non SQL clients to be able to connect to the server currently hosting the database so that they can run scripts sitting in a share. I don't have a shared disk so just have a directory share on each server with the same scripts in each directory.
I am able to ping and RDP to the listener IP address/name and end up on the correct server but am unable to connect to the share ListenerNameShare. Is that actually supported? If it is, any thoughts on what I need to do to get it going. If it isn't what other options do I have?
So I have Availability groups configured as well as the Availability Group Listener, what If I want to change the port that the listener is listening on, do I need to reboot the server or is it dynamic across the board ?
View 5 Replies View RelatedI am trying to setup an AG on a cluster, I was able to define where I want my replica, but I need to setup the ip for the listener of that one
When I am adding the Ip at the listener I am getting the following message:
The Windows Server Failover Clustering (WSFC) resource control API returned error code 5057. The WSFC service may not be running or may not be accessible in its current state, or the specified arguments are invalid. For information about this error code, see "System Error Codes" in the Windows Development documentation.
The attempt to create the network name and IP address for the listener failed. The WSFC service may not be running or may be inaccessible in its current state, or the values provided for the network name and IP address may be incorrect. Check the state of the WSFC cluster and validate the network name and IP address with the network administrator. (Microsoft SQL Server, Error: 41009)
Browsing around I found this guide: [URL] ......
And I make sure that the cluster has permissions to "Read all properties", "Create Computer Objects", even to "Create all child" permissions
I also added those permissions to the account that starts sql at that cluster and I am logged as that and I am still getting the error....
After manual AG fail-over from primary to secondary the application is not able to connect the listener name for atleast for 5 - 10 mins
The telnet fails during this time from app server, the listener ip is on muti-subnet.
At the same when i try to connect it from SSMS from a remote machine it works fine.
