What is the difference between CleanExpiredCache and FlushReportFromCache Do we need to run both the SPs to clear all the SSRS reporting cache? Is it possible to clean all the Cache information and retain the logs? If yes how we can do so. Is it by deleting the REportServerTempDB.dbo.ExecutionCache table work in achieving this?
View 8 RepliesIs there a way to drop clean buffers at the database level instead of the server/instance level like the undocumented DBCC FLUSHPROCINDB (@dbid)??
Is there a workaround for dbo? to be able to flush procedure and data cache without being elevated to sysadmin? server role?
PS: I am aware of the sp_recompile option that can be used to invalidate cached execution plans.
Thx.
Hi,
My problem is that I cannot completely clean buffer cache on SQL Server 2005 version 9.00.2047.00 (probably SP1).
Right after I run DBCC DROPCLEANBUFFERS in the context of my database (this is development server, and so far I am only the one who is working with a particular database), I run a script that quetries sys.dm_os_buffer_descriptors view also from the context of my database to make sure that the buffer cache is really clean. However it shows large number of entries totalling 42 MB.
I ran both DBCC an the script in the past too, and it always showed nothing in the results, that means that buffers were really clean. The reason why I am running this is for benchmarking of existing and new application.
Does anybody have any idea, suggestions, how to troubleshoot this issue ? I already closed all connections to this database, but rebooting the server is not an option since other people are also working on it.
Thanks
I have a report whose parameters are limited by the user who is logged in. Ex. if a user had full access they would see all 100 hospitals in our hospital parameter, if another user had limited access they might only see 5 - this will vary largely on who is logged in. The data source that drives these parameters are set as follows:
Credentials stored securely in the report server, username and password are entered and Impersonate the authenticated user after a connection has been made to the data source is checked.I now want to cache this report for X minutes. So I goto Properties/Execution and select 'Cache a temporary copy of the report. Expire copy of report after a number of minutes'.
Applying this gives me the error: Credentials used to run this report are not stored.
I have a dashboard page that I would like to load fast. But I would also like the user to be able to run the report On-Demand. The report has start date and end date parameters which default to the first and last day of last month. If I use a Cache plan that loads at 6AM the report runs with the default parameters set in the report, the user has to wait until it completes before they can change the parameters.
If I uncheck "use default" parameters in the report I lose the ability to set a cache refresh plan with the default parameters because the option is greyed out. So is there anyway outside of creating a second copy of the report to allow a user to open a report, change the parameters and run it, but also have a way to schedule some sort of Cached report for the default parameters so I can put that on a WebPart page that would load instantly?
in microsoft doc there is written on the topic of BP Extensions with SSD's in SQL Server 2014: only clean pages are written to disk... does this mean data pages that have not been modified yet? or also those data pages that have already been modified, and where log has finished writing and the transaction has been marked as commited??
why are there clean data pages being written to L2 cache to make space for other not modified pages? I mean, shoudnt they be modified first, before letting other unmodified data pages into the Cache? I mean they have still to be modified..that makes no sense to me to page them out and page them in again just for other data pages...
Has anyone ever worked with the Reporting Services Device Information Settings (Render or HTML method) If so, were do I begin. I have read all of the articles and have xml examples but I don't know where to start?
Do I make the change in SSRS?
Do I make the change on the field that I want to alter?
Do I make the change on the report header properties?
What is the first step?
I want to change the excel device info parameter settings simplepageheaders = true. How would I go about doing this?

Hi,
I developed a report in development environment, which will later be deployed to QA, Staging and then Production. This report has more than 10 datasets and if the report is moved through each of the databases, datasource has to be changed for all the datasets. is there anyway that I can do it globally, what i mean is can i set up any configuration files which I can use in QA, Staging and Production.
Any ideas
Thanks,

I have a query where I am trying to display the most recent information about travelling method of customers using "t.collection_date". I am struggling to get MAX function working in the query.
SELECT P.id, P.forename, P.surname, P.dob, c.postcode, l.code_des, MAX(t.collection_date)
FROM People p,
MOT_HIST t,
lk_mode_of_travel l,
corresp_address c
WHERE p.ID = t.id (+)
AND t.mode_of_travel = l.int_code (+)
AND p.id = c.entity_id (+)
Maybe I am just a lot better at this than I thought, but I figure that somewhere there is a mathematical rule that is being overlooked. When I run dbcc sqlperf (lrustats) on some of my production machines, I sometimes end up with a cache hit ratio (which is defined as a percentage, mind you) that is slightly over the limit:
Statistic Value
-------------------------------- ------------------------
Cache Hit Ratio 100.00898
Cache Flushes 0.0
Free Page Scan (Avg) 0.0
Free Page Scan (Max) 0.0
Min Free Buffers 331.0
Cache Size 4362.0
Free Buffers 9434.0
I suspect some counter somewhere is getting wrapped around its 4 byte limit. Is there any reliable source for getting statisics about SQL Server performance? Users tend be unreliable and say everything is slow.
I am loading data using SSIS 2008 from a table in SQL Server 2008 DB to excel 97 sheet pre-defined with column headers. All the columns in excel is has 'Text' format property and the columns in the SQL Server table are defined as nVarchar. One of the columns has trailing spaces in few rows in DB but after exporting to excel 97, the spaces are gone. We need to retain the whitespaces in the column values. How can we do that.

Hi,
When I generate a report I pass an id(guid) so it knows what record to get information for, now if I hit the "generate report" button on my application I will get the report, but if I change the record and hit the "generate report" button again, I get a cached copy of the report. I looked at several sources for a solution, I ended up adding 3 parameters:
rs:ClearSession=true
rcarameters=true
rc:emissionTime=System.DateTime.Today.Ticks.ToString()
I just tested again, and did not work. Can you help me solve this issue?
Thanks.
How do I know when its the right time to use the Cache Connection Manager? I understand that Full Cache mode eliminates the need to query the lookup table for every row.
Is the Cache Connection Manager intended for use by multiple packages that need access to the same lookup data?

It's driving me crazy, why is it looking for 'ReportServerTempDBTempDB' in the catalog instead of 'ReportServerTempDB'?
Is it possible to migrate from 32bit to 64bit?
Any help is appreciated
I've a simple lookup transform in SSIS 2008 (R2). I've created it with a full cache and it worked fine. When i switch to partial cache, it will give me this error:

TITLE: Package Validation Error

ADDITIONAL INFORMATION:
Error at DFT_AdventureWorks [Lookup [411]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
[Code] ....
I've created a OLE source with the following query :
SELECT
SalesOrderID,
OrderDate,
CustomerID
FROM Sales.SalesOrderHeader
And this will flow into the lookup transform and this has the following lookup reference query:
SELECT CustomerID,
AccountNumber
FROM Sales.Customer
WHERE CustomerID % 7 <>0
I am using a lookup and full cache, occasionally i get this warning:[Lookup [150]] Warning: The component "Lookup" (150) encountered duplicate reference key values when caching reference data. This error occurs in Full Cache mode only. Either remove the duplicate key values, or change the cache mode to PARTIAL or NO_CACHE. Now I know it is only a warning but it is highlighting a real issue.Is there a way of capturing that this has happened?
View 6 Replies View RelatedWe are using the cache transformation in our project , while doing the cache transformation our disk space goes to 0 MB free and SSIS package execution not completes even after 3 hr..Initially we have around 34 GB free space on C: drive .Our server configuration is 64 RAM. We are caching the data from table which contains around 21 million records.We changed the path in properties (“BLOPTempStoragePath”,”BufferTempStoragePath”) of Data Flow task of SSIS in which we are using Cache Transformation.
View 6 Replies View RelatedI work in the healthcare area, and am handling the survey data ETL's. There are around 8 different survey areas and based on information received from them for the visit they reference, I want to pull in more info from our invoicing database. My idea is this:
1.) Pull in the flat file to an ODBC staging table
2.) Cache all invoice records that fall between the MIN(Date of Service) and MAX(Date of Service) from the staging table.
3.) First lookup the information needed on patientID, providerID, date of service, and billing location.
4.) For the surveys that didn't match on those 4 columns, try looking up based on patientID, date of service, and billing location (since I could be 99% sure this would still return the record I need).
5.) For the remaining surveys, lookup based just on patientID and date of service. These records will be flagged for manual review because clearly, if a patient has multiple appointments in the same day, this will be prone to error.
However, in trying to use only 3 of the columns in the lookup, I get the error saying basically that I need to utilize all 4. Is there a way around this, or is there an entirely different way I should be approaching this? The reason I thought cache transform was the answer is because I will need to run a different package for each lookup, as the data and logic between each survey will vary, but the invoice data "pool" will stay the same regardless.
Hi guys,
I am looking at the plan caches/cached pages from the perspective of
sys.dm_os_memory_cache_counters and sql serverlan Cache - Cache Pages
For the first one I am using
select (sum(single_pages_kb) + sum(multi_pages_kb) )
from sys.dm_os_memory_cache_counters
where type = 'CACHESTORE_SQLCP' or type = 'CACHESTORE_OBJCP'
a slight change from a query in
http://blogs.msdn.com/sqlprogrammability/
For the second just perfmon.
The first one gives me a count of about 670,000 pages only for the object and query cache and the second one gives me a total of about 100,000 pages for five type of caches including object and query.
If I am using the query from http://blogs.msdn.com/sqlprogrammability/ to determin the plan cache size
select (sum(single_pages_kb) + sum(multi_pages_kb) ) * 8 / (1024.0 * 1024.0) as plan_cache_in_GB
from sys.dm_os_memory_cache_counters
where type = 'CACHESTORE_SQLCP' or type = 'CACHESTORE_OBJCP'
it gives me about 5 GB when in fact my SQL Server it can access only max 2GB with Total and Target Server Memory at about 1.5 GB.
Does anyone have any idea what is going on?
Hi Friends,
I was in the phase of switching over to Sql Server Reporting from the normal reports. I plan to go with the SQL server 2005 standard version. Do i need visual studio 2005 to design and deploy report. If I am using only SQL server standard alone for my reporting and publishing, is it possible to assign the user rights to reports, user can just login and can view all the reports that belongs to that user. Since I wont be using the visual Studio 2005, so I want to implement this using the SQL server 2005. So pls help me with your kind information how to proceed ahead.
Thanks,

and use
IDTSConnectionManagerCacheColumn100 id = connMgr.Columns["Id"]; get the column info.
but how do i get the cache connection content ?I want to look in the content in a script component code.
I'm currently loading a package that does a lookup on a column of data type nvarchar(4).The values itself are (A+, A, B+, B, C, D, /). The strange lookup behaviour is happening for each of the cases, so it's not related to a specific value. After trying to put the cache on NO CACHE, the lookup works perfectly. When using the default FULL CACHE the strange behaviour happens. Could it be related to the data type? I have not yet tried to use a CHAR instead of a NVARCHAR but it looks like people have similar issues using CHAR.
View 2 Replies View RelatedI'm attempting to obtain a cost effective solution for my existing customers to develop reports on their SQL 2000 Server installations using their Reporting Services 2000. With products like Visual Basic.NET 2003 becoming almost impossible to obtain, I have at least one customer who is running into a dead end.
One option possibly is the SQL Express with Advanced Services download, which has Reporting Services. My questions are as follows:
Can the report designer component of SQL Express Reporting Services be configured to connect to an external database (which would happen to be a SQL 2000 database) to establish its datasets?
Does the resultant designed report end up in an RDL file? If the customer published this report via the Reporting Services 2000 Report Manager, would the report be able to run?
Sorry for asking a question like this that I could probably answer on my own, but my customer needed this answer yesterday. I have scoured the web and microsoft sites - and posted a question on the official SQL Reporting Services cateogy ... in an attempt to answer the basic question of how to design reports for Reporting Services 2000 in the absence of Visual Basic.NET 2003 (or other .NET 2003 tools) with no success.
Thanks to anyone who can help.

I work in a big project and we will begin in using reporting services as the base technique for reports and I will be responsible for this part. but I have a problem I will discuss in the following:
Currently: We use currently devexpress reports and we have 2 languages(Arabic and English). the data in tables saved in two ways (Arabic and English). when the end user change the language of the web site the report data language changed when run it.
Example:
we have table with (ID, NAME_AR, NAME_EN, JobTitle_AR, JobTitle_EN). designed report will display(ID, NAME_EN, JobTitle_EN) . but the end user change the language of the system the report will
dispaly(ID, NAME_AR, JobTitle_AR)
Hint:this done pragmatically
how to do this in reporting services.
Q1: Any way to control which db loads when, and perhaps stop this error from happening? Again- when all is said and done, the report server functions, and I am able to access just fine.
Q2: What kind of recovery is being referred to? Given the message type- I assume it's nothing of concern- probably more to do with a system that doesn't run all the time.
Okay- so I get these two event messages each time I boot.
Below are two error message I see daily with each system boot- the services mentioned do "actually" function, and are running- as not 10 seconds after these messages are logged, the successfully loaded messages appear. It's almost as if report services tries to connect before the databases are up and running.
Basically the sequence (today) was:
1. 05:49:01 Failure Audit (MSSQL$SQLEXPRESS)
2. 05:49:01 Error (Report Server Windows Service (SQLEXPRESS)
3. 05:49:02 Recovery is complete. (EventID 3408 MSSQL$SQLEXPRESS)
4. 05:49:06 Starting up database 'ReportServer'
5. 05:49:09 Server Resumed execution (MSSQL$SQLEXPRESS)
I'm assuming based on the events that Report Server Service attempts to connect to the ReportServer database before it's actually started. Doesn't really explain the failure audit-
1. Failure Audit:
Event Type: Failure Audit
Event Source: MSSQL$SQLEXPRESS
Event Category: (4)

This is almost immediately followed by this (which I consider a no-brainer, considering the above):
