Best Way To Retrieve Oracle Data Into SS2000 Near Real-time?
Jul 19, 2007
I have no idea where to post this kind of question, so here it is!
I have a requirement to retrieve oracle 10 data into SS2000 in as near real-time as possible (stupid users!) and join with resident SS data for on-demand reporting. (We use SS replication to populate some reporting tables from other SS2000 instances and this has spoiled the users as well as the developers! )
I would like to know if there are any clever ways of doing this, or if a plain-old DTS package running in some kind of loop is the practical answer. 1 minute delay is probably too long . . . I don't know if data can be pushed from the oracle side. Or if we need to write a Service and use it to suck and push.
Any suggestions?
thanks!

I currently have an application which retrieves stats from a SQL database that are updated throughout the day. My application updates every 3 seconds to retrieve these stats but I found that it's quite expensive to the server's CPU when there are several clients running my application. Are there any other methods for extracting the data that won't require so much CPU. The fact that the database is being hit so much isn't good either. I have already written a webservice hoping that this would improve things but I'm not sure it has.

Hi
I´m a SysAdmin and I´m implementing ASSP (anti-spam) to use with an email server.
But the ASSP requires a txt file with all domains hosted in the server that are in a SQL Table of the server.
My questions is: Is there anything to make a real time TXT file with all the domains ?
maybe use trigger I dont know..

Hi there,
I was wondering about the stability of SSIS when it comes to importing data on a real-time basis. Let's say you have a scenario where flat files, for instance, will be dropped at random intervals ranging from 1 second to 10 seconds apart and the importer has to import these files immediately.
I would imagine that this is done with a package which runs a loop sniffing the directory forever but I stand corrected on the best ways of doing it.
I'm not too sure whether SSIS is a good idea for this as lots of people have had bad comments on SSIS in real-time in my company but they cannot elaborate on why enough to convince me. I have done some pretty cool stuff and must admit that I am a fan of the technology but dont want to defend it into a corner
Please give me your thoughts on this
Regards
Michael

I am about to prepare a paper concerning the field of real-time data mining. Real-time here means the process of incremental training of an existing model as soon as the data arrives.
There is a number of papers introducing algorithms for incremental association analysis, incremental clustering etc. Stream mining Ãs a field which is closely related to that. The main reason for the implementation of incremental algorithms is a) the large amount of data to be mined and b) the high rate of new data that is evolving every day.
Using classical batch mining algorithms, models that are outdated for some reason, would have to be re-trained, which could be very time consuming for billions of records. And once the training is completed, the training would have to be restarted once again because a bulk of new data has been arrived.
The question that I would like to discuss now is: For what real world applications would it be a meaningful or even essential to use real-time training of models?
Two main reasons could determine the answer to that question:
You just want to incorporate new data into existing models in order to increase the prediction accuracy of your model or
Your underlying data is subject to more or less massive changes (also refered to as concept drift) and you want to adapt your mining model continuously to that reality.
I'm looking for some examples or ideas where one of these cases apply and it would be a good idea to have incremental mining algorithms involved.
I'm looking forward to inspiring some discussion on that issue.

I want to build a windows application in Visual Studio 2005 that grabs some data from a SQL DB and displays it in a gridview. That is easy and I already have it done, but I also want to know how to show this data in real-time. For example: right now we have a application that pulls some login information for all the users and displays their phone extension, their name, and their status. They can change their status by clicking on some radios below the datagrid and on change it updates the data and then posts back. However, I dont know how the guy who did it made it so that these local changes are automatically shown on everyone elses computers around the office. In other words, they are shown the live data as it changes, without having to refresh it or anything. How would I go about doing this or does anyone have any places/resources that could help me accomplish this task. Thanks.
Oh and the guy who wrote this is no longer working here and he deleted the source code so i cant look at it.

Is there a way to keep track in real time on how long a stored procedure is running for? So what I want to do is fire off a trace in a stored procedure if that stored procedure is running for over like 5 minutes.

Hi guys,
When I thought everything is okay with this script, I got a new problem...
I have a VBA's script from Excel 2003 that builds sql script and retrieves data from SQL SERVER 2000.
in order to make the sql running, I need to use a multi - batch processing, to pass and execute every command line once a time.
Up to here, I am using a test case with Account number = '123456' and getting the desire results.
The code below is running okay with the test case, but when changing the account number (mark as yellow in the code) to include all the accounts (or just one other account), I am getting the following ERROR:
run - time error '-2147217871 (80040e31)' - [Microsoft] [ODBC SQL Server Driver] time out expired.
Now, if I take the same code, with the condition that generates the ERROR, and try it into SQL Server, I get the results without errors.
Thanks in advance,
Aldo.
Below the code:

Hi all.
I have posted this question in another forum but no one has so far been able to provide a solution to the problem. Since I know Database Journal always has very informative and enlightening posts, I figured I'd post the question here in hopes that some guru can provide an answer.
If you're running SQL 2000 and have any jobs that have been executed, you could perform a query as such:
select last_run_time from msdb.dbo.sysjobsteps
and receive returned values that contain the last time a job was executed "stored in integer datatype" columns. See ->
sp_help sysjobsteps.
In SQL 2005 I believe the concept is the same. I think the intent of Microsoft had it mind for doing this was to store the date separate from the time values which won't work using the datetime datatype and I have read this in documentation in the past.
The challenge is to convert that data into a humanly legible 12 or 24 hour time format like 11:00 AM or 02:45:39.
Does anyone have any suggestions or clues to assist in resolving this problem??? :(
Thanks.

We are using SQL 7 at 2 different locations, on 2 different Domains that are connected via a T1 line.
We need to have our 2 SQL servers be identical at all times, meaning when a change is made on one server, it is immediately replicated to the other. The problem is that both servers are always being used, so there is no primary/backup server scenario.
Does anyone know if there is a third party software available, or if this is even possible to do, given the fact that the databases are always open ?
Thanks.

i have 2 DB in 2 different servers.
db1 and db2
db1 gets 150k records every hour. db2 is like the backup of db1. db2 is used to retrieve records to create reports using reporting services.
what is the best way to synchronize db2 with db1?
is it to create a dts package and set up a job that runs every hour?
off topic question.
what kind of language does reporting services use to create the reports?

The ETL processing for my project will be deployed as part of a larger application which is operated by non-technical users. Therefore I want to provide real-time feedback to the user on progress, errors, etc., using windows standard GUI interface objects and style- for example a progress bar. The "designer" of course does some of this but there won't be any designer in our deployed application (and SSIS designer is neither intended to be used by, nor appropriate for, non-technical users anyway).
Now that I have the ETL logic working, it's time to tackle this UI requirement. I am thinking one way to do this is to start a script task to run in parallel with the main ETL processing, open a winform in that task that has various GUI objects whose "state" is based on package scoped variables, update the package level variables via the "on progress" event (or other events as needed) of various SSIS tasks and components, and refresh the winform's display regularly via a timer event.
Does this approach seem like it would be effective? Has anyone tried maintaining an open winform via a script task and updating it's objects via package variables in parrallel with the package is running other tasks?
Thanks,
Ken

Hi,
We currently have a propriety in memory DB that is used to store the latest transactions in the system and we have a service that copies the data to a SQL Server every couple of seconds - For historical reporting purpose.
We would like to move into a more standard DB as our real time DB, since we have scalability and availability issues. We taught about using SQL Server since this is the DB we know, but I'm not sure it's built to handle real time data.
Does someone has any experience in using SQL Server for "Real Time" applications?
Does someone has any experience in storing the data files on RAM?
Does MS has a solution similar to Oracle's TimesTen, which is their real time DB?
Thanks,
Avi G..

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.
Joan

I'm sure just about everyone uses the PRINT command to give feedback as to what their lengthy and involved scripts are doing, as sort of a record.
I cannot figure out how to make the stuff I use in PRINT commands come out in real-time like SELECTs seem to. Does anyone have an answer to this? These are long-running scripts, and I'd rather nip a problem in the bud before the entire script completes if there's a problem I can capture.

Hi
There are 2 databases db1 and db2 on SQL server 7 with tables 1 and 2 respectively.
Both these tables have a field called Quantity. IF quantity gets updated in table 1 then that change should be immediately reflected in table2.
I though an update on table1 would serve the purpose but this trigger doesn't seem to be working however there are no errors during the syntax check.
The code for the trigger that i have used on table 1 is as below
CREATE TRIGGER [Qty_UPDATE] ON [Table1]
FOR UPDATE
AS
IF UPDATE (Qty)
BEGIN
UPDATE db2.dbo.table2
SET db2.dbo.table2.qty = qty
END
Please help
Thanks in advance

I saw a presentation last week where the speaker created some sorta sql server "watch window" (in Sql Server Management Studio I think) where he could watch all the commands being executed on his sql server database in real-time. For example he could navigate to web pages (that hit the database) and as he pressed buttons you could see the sql commands execute in this "watch window." If other users hit the database at the same time you could see those sql queries execute as well. I didn't think at the time to ask how he did it - does anyone know how to set this up? I have a problem with my sql server right now and it would be useful to see which sql queries (etc) are being executed when. Thanks in advance,J. Shane Kunklejkunkle@vt.edu
