Is there a way to setup in Oracle SQL Developer an initial filter for table Data view tab or switch off automatic data load?
I work with a team of analysts whom start analysis by entering that tab and yet keep avoiding manual writing sql. Initial data load last over half minute and pressing cancel on loading dialog with progress bar makes that tab useless.
Just want to make life of these guys bit easier.
The answer is 'no' - filters aren't currently persisted across sessions of SQL Developer.
I would suggest Pravin's answer regarding views OR
Create an APEX front end application for data entry for your business users, it's a perfect use-case for APEX.
There is a request on the feature exchange, check this out.
Why not create a view on these tables with initial filter ? Instead of table team can query these views. You can limit columns also which team needs.
I am running into issues with out of memory exceptions . I need to display a large set of data in a cross tab. I need to display 5,277,888 rows aggregated into 403,920 rows. I don't think birt can handle this and would like some advice.
These are the options I was thinking
Some how fetch some data at a time and aggregate it (might still run out of memory)
Find a different reporting framework that renders html
Not use cross tab and do all of the aggregation server side and try to display it in a sudo cross tab.
Fetaching large amonunt of data and providing it to BIRT increases data trafic and also many a times (as in your case) lead to system / report engine hang.
What you are thinkning is correct. (Option 3) It is preferable to use aggregate functions in your db and give an already summarized data to BIRT at times.
SQL provides options for cross tab outputs (SQL Pivot Function) as well in case required.
I have a stored procedure that returns about 50000 records in 10sec using at most 2 cores in SSMS. The SSRS report using the stored procedure was taking 20min and would max out the processor on an 8 core server for the entire time. The report was relatively simple (i.e. no graphs, calculations). The report did not appear to be the issue as I wrote the 50K rows to a temp table and the report could display the data in a few seconds. I tried many different ideas for testing altering the stored procedure each time, but keeping the original code in a separate window to revert back to. After one Alter of the stored procedure, going back to the original code, the report and server utilization started running fast, comparable to the performance of the stored procedure alone. Everything is fine for now, but I am would like to get to the bottom of what caused this in case it happens again. Any ideas?
I'd start with a SQL Profiler trace of both the stored procedure when you execute it normally, and then the same SP when it's called by SSRS. Make sure you include the execution plans involved, so you can see if it's making some bad decisions (though that seems unlikely - the SQL Server should execute an optimal - or at least consistent - plan regardless of the query's source).
We used to have cases where Business Objects would execute stored procs dozens of times for no aparent reason and it lead to occasionally horrible performance, though I've never seen that same behavior with SSRS. It may be somewhere to start, though. You'll also see the execution begin/end times - that will make it clear if it's the database layer that's hanging up, or if the SQL Server hands back the data in 10 seconds and then it's the SSRS service that's choking somewhere.
The primary solution to speeding SSRS reports is to cache the reports. If one does this (either my preloading the cache at 7:30 am for instance) or caches the reports on-hit, one will find massive gains in load speed.
You may also find that monthly restarts of SSRS application domain to resolve your issue.
Please note that I do this daily and professionally and am not simply waxing poetic on SSRS

If you do not like initial reports taking long and your data is static i.e. a daily general ledger or the like, meaning the data is relatively static over the day, you may increase the cache life-span.
Finally, you may also opt for business managers to instead receive these reports via email subscriptions, which will send them a point in time Excel report which they may find easier and more systematic.
You can also use parameters in SSRS to allow for easy parsing by the user and faster queries. In the query builder type IN(#SSN) under the Filter column that you wish to parameterize, you will then find it created in the parameter folder just above data sources in the upper left of your BIDS GUI.

I have an SSRS report that calls out to a stored procedure. If I run the stored procedure directly from a query window, it will return in under 2 seconds. However, the same query run from an 2005 SSRS report takes up to 5 minutes to complete. This is not just happening on the first run, it happens every time. Additionally, I don't see this same problem in other environments.
Any ideas on why the SSRS report would run so slow in this particular environment?
Thanks for the suggestions provided here. We have found a solution and it did turn out to be related to the parameters. SQL Server was producing a convoluted execution plan when executed from the SSRS report due to 'parameter sniffing'. The workaround was to declare variables inside of the stored procedure and assign the incoming parameters to the variables. Then the query used the variables rather than the parameters. This caused the query to perform consistently whether called from SQL Server Manager or through the SSRS report.
I will add that I had the same problem with a non-stored procedure query - just a plain select statement. To fix it, I declared a variable within the dataset SQL statement and set it equal to the SSRS parameter.
What an annoying workaround! Still, thank you all for getting me close to the answer!
Add this to the end of your proc: option(recompile)
This will make the report run almost as fast as the stored procedure
I had the same problem, here is my description of the problem
"I created a store procedure which would generate 2200 Rows and would get executed in almost 2 seconds however after calling the store procedure from SSRS 2008 and run the report it actually never ran and ultimately I have to kill the BIDS (Business Intelligence development Studio) from task manager".
What I Tried: I tried running the SP from reportuser Login but SP was running normal for that user as well, I checked Profiler but nothing worked out.
Solution:
Actually the problem is that even though SP is generating the result but SSRS engine is taking time to read these many rows and render it back.
So I added WITH RECOMPILE option in SP and ran the report .. this is when miracle happened and my problem got resolve.
I had the same scenario occuring..Very basic report, the SP (which only takes in 1 param) was taking 5 seconds to bring back 10K records, yet the report would take 6 minutes to run. According to profiler and the RS ExecutionLogStorage table, the report was spending all it's time on the query. Brian S.'s comment led me to the solution..I simply added WITH RECOMPILE before the AS statement in the SP, and now the report time pretty much matches the SP execution time.
I simply deselected 'Repeat header columns on each page' within the Tablix Properties.
If your stored procedure uses linked servers or openquery, they may run quickly by themselves but take a long time to render in SSRS. Some general suggestions:
Retrieve the data directly from the server where the data is stored by using a different data source instead of using the linked server to retrieve the data.
Load the data from the remote server to a local table prior to executing the report, keeping the report query simple.
Use a table variable to first retrieve the data from the remote server and then join with your local tables instead of directly returning a join with a linked server.
I see that the question has been answered, I'm just adding this in case someone has this same issue.
I had the report html output trouble on report retrieving 32000 lines. The query ran fast but the output into web browser was very slow. In my case I had to activate “Interactive Paging” to allow user to see first page and be able to generate Excel file. The pros of this solution is that first page appears fast and user can generate export to Excel or PDF, the cons is that user can scroll only current page. If user wants to see more content he\she must use navigation buttons above the grid. In my case user accepted this behavior because the export to Excel was more important.
To activate “Interactive Paging” you must click on the free area in the report pane and change property “InteractiveSize”\ “Height” on the report level in Properties pane. Set this property to different from 0. I set to 8.5 inches in my case. Also ensure that you unchecked “Keep together on one page if possible” property on the Tablix level (right click on the Tablix, then “Tablix Properties”, then “General”\ “Page Break Options”).
I came across a similar issue of my stored procedure executing quickly from Management Studio but executing very slow from SSRS. After a long struggle I solved this issue by deleting the stored procedure physically and recreating it. I am not sure of the logic behind it, but I assume it is because of the change in table structure used in the stored procedure.
I Faced the same issue. For me it was just to unckeck the option :
Tablix Properties=> Page Break Option => Keep together on one page if possible
Of SSRS Report. It was trying to put all records on the same page instead of creating many pages.
Aside from the parameter-sniffing issue, I've found that SSRS is generally slower at client side processing than (in my case) Crystal reports. The SSRS engine just doesn't seem as capable when it has a lot of rows to locally filter or aggregate. Granted, these are result set design problems which can frequently be addressed (though not always if the details are required for drilldown) but the more um...mature...reporting engine is more forgiving.
In my case, I just had to disconnect and connect the SSMS. I profiled the query and the duration of execution was showing 1 minute even though the query itself runs under 2 seconds. Restarted the connection and ran again, this time the duration showed the correct execution time.
I was able to solve this by removing the [&TotalPages] builtin field from the bottom. The time when down from minutes to less than a second.
Something odd that I could not determined was having impact on the calculation of total pages.
I was using SSRS 2012.
Couple of things you can do, without executing the actual report just run the sproc from within the data tab of reporting services. Does it still take time?
Another option is to use SQL Profiler and determine what is coming in and out of the database system.
Another thing you can do to test it, so to recreate a simple report without any parameters. Run the report and see if it makes a difference. It could be that your RS report is corrupted or badly formed that may cause the rendering to be really slow.
Had the same problem, and fixed it by giving the shared dataset a default parameter and updating that dataset in the reporting server.
DO you use "group by" in the SSRS table?
I had a report with 3 grouped by fields and I noticed that the report runed very slowly despite having a light query, to the point where I can't even dial values in the search field.
Than I removed the groupings and now the report goes up in seconds and everything works in an instant.
In our case, no code was required.
Note from our Help Desk: "Clearing out your Internet Setting will fix this problem."
Maybe that means "clear cache."
I'm using Crystal Reports 11 (and VB6) to open a report file, load the data from an Access database and either print the report to a printer or export the report to another .rpt file (for later printing without the database)
Even for small amounts of data the process is somewhat slow. Profiling showed about 1.5 seconds for three records (one page) For about 500 records on 10 pages, it's 1.7 seconds.
Can I do something the speed it up? Can I tweak the data or the report?
This is just an idea, but I 'd first try to build a view on the server, so that CR can directly access the report's data without dealing with any join or filter or whatever on the user's side. I have read terrible things about CR querying the server multiple times with the same query before displaying the report ...
Seeing that there are no other replies I'll just post what I'm really thinking and that is honestly I wish my Crystal Reports 11 app was as fast as yours. In my application there are so many suppressed fields and sections that Crystal just drags for about a minute to generate any report.
