erratic performance with data warehouse query...

Posted By:      Posted Date: October 16, 2010    Points: 0   Category :Sql Server

Ok I am running into some very strange performance issues with this one particular query. 



FROM Enrollment.Processing.Enrollment_Audit a

INNER JOIN Enrollment.Dim.EquipmentType n ON n.EquipmentType = a.Equip_Type

INNER JOIN Enrollment.Dim.ClientID t ON t.Client_ID = 214

INNER JOIN Enrollment.Dim.DealerCode q ON q.Client_ID = 214 AND q.DealerCode = a.DealerCode AND q.EndDate IS NULL

INNER JOIN Enrollment.Dim.DealerCode u ON u.Client_ID = 214 AND u.DealerCode = a.PurchDealerCode AND u.EndDate IS NULL

INNER JOIN Enrollment.Dim.Device i ON i.Client_ID = 214 AND i.Make = a.PMake AND i.Model = a.Pmodel AND i.ClientMarket_ID = a.ClientMarket_Id AND i.EquipmentTypeKey = n.ID

INNER JOIN Enrollment.Dim.ExtendedDevice d ON d.Client_ID = 214 AND d.Device_ID = a.Device_ID AND d.ESN = a.ESN AND d.Mobile_IDN = a.Mobile_IDN

INNER JOIN Enrollment.Dim.Market l ON l.Client_ID = 214  AND l.Market_Code = a.Market_Code

INNER JOIN Enrollment.Dim.Source o ON o.

Web Farms: Use Data Caching Techniques to Boost Performance and Ensure Synchronization


Performance is an important concern for any application, but becomes critical when the app is a Web Service accessed by thousands of clients simultaneously. One hardware approach to distributing Web Services requests evenly is a Web farm consisting of multiple servers. Once on a Web farm, Web Service performance can be improved by using ADO.NET DataSet objects to cache frequently accessed data, reducing round-trips to the database. Here the author describes data caching in a Web farm environment and discusses how to avoid the cross-server synchronization problems inherent in this approach.

Query Performance & Overall Design - SSAS MDX WCF

Hi All, We have a Cube which is to be queried by the Online system , using WCF service. Peroformance of the queries running on the Cube is not really very good , as we have to calculate various percentile (which are all calculated members) on the cube, this howver works well within limits of 5-6 secs for small sample size. But this goes beyond the threshold of 30 secs when the record counts increases. What we have is our SSAS Cubes , and we have WCF Service querying the Cube using ADOMD.NET. This may not be one of the best way to achieve this requirement , but we are kind of completed with development and it may not be feasible to work on another approach, what we are looking for is optimize this design and make it work with in expected time limits of 5-8 secs. Kindly let me know, if i am not clear or if you need any more info to suggest something ! Thanks a lot for your help !   Kindly

Oracle Linked serve Query performance in 2000 vs 2008 R2 64 Bit

Hi everyone We have started to migrate one of our reporting systems from Sql 2000 to Sql 2008 R2.  One of the steps has been to test the perforance of certain Oracle linked server queries between each server.  We are finding on average 3 fold better perforance stats (in terms of query completion time) on the old server.  This should obviously not be the case.  The new server has signifantly more CPU/Memory/IO resources to play with, and it is 64 bit (not to mention its new!).  Here's what I got so far: Old server: SQL 2000 on W2000 both fully patched.  Old Dell Dual core with 3 GB of Ram running on two soft IDE Mirrored drives (yes I know... it sucks).  It connecting via the MS OLE DB provider for Oracle (9i client) New server: ESX VMware Server with 2 CPU's assigned, 8 GB of ram connected to large HP SAN.  CPU, ram and IO's have all been ruled out as the problem.  We've tried varying network cards with different results so we havent ruled that out yet.  Its connecting via the Oracle provider for OLE DB (11G 64 bit client) The linked server is an Oracle 9i fully patched server.  All three are on the same network backbone. Running a simple select * query on both servers returns the same number of rows (~76 000) .  It takes ~1:20 on the new server and ~0:20 on the old server. In looking at the wait stati

SQL Query to retrive the data in XML Predefined tag format

I am looking out the way for  instead of using column names as tags, be able to use a predefined mapping. For example Select firstname from employee <firstname>John</firstname> Instead, Have a file that maps the firstname to fname so when we run the TSQL should get:  <fname>John</fname> Please consider that there are over 100 columns in the Query for which how can I use the predefined format.  Sivaprasad S http://sivasql.blogspot.com Please click the Mark as Answer button if a post solves your problem!

Full text performance of a certain query

I am doing a full text query on a very simple table and when I include the search term "y5v" in the conditions it slows the query down like 8 to 1. The table is defined as: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[tblTextSrchData]( [intItemId] [int] NOT NULL, [srchTxt] [varchar](max) NOT NULL, CONSTRAINT [PK_tblTextSrchData] PRIMARY KEY CLUSTERED ( [intItemId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] Here is the query: SELECT II.intItemID, KEY_TBL.[RANK] as Score FROM tblItems II INNER JOIN CONTAINSTABLE(dbo.tblTextSrchData,srchTxt, '("capacitor" OR FORMSOF(INFLECTIONAL, "capacitor") OR "capacitor*") AND ("active" OR FORMSOF(INFLECTIONAL, "active") OR "active*") AND ("y5v" OR FORMSOF(INFLECTIONAL, "y5v") OR "y5v*")') KEY_TBL ON KEY_TBL.[KEY] = II.intItemID If I take any of the additional search terms out it improves performance.  If I remove the yv5 search term the results are returned in less than a second. What seems to be the problem is for some reason when I add yv5 it starts doing these sorts after the full text matching.  These sorts take most of the time.  I'm not sure

How to query for id's of the fields with List Data Retrival Services Query() web service

Since i marked a post as answer in my previous topic, it seems that people dont visit the topic anymore as they see it as "answered" while it actually is only partially answered. So i guess i have to ask again in a different topic.    I need to get data from Sharepoint Server (3.0 i belive) for my Integration Services project. For that i use Sharepoint's webservices. I've read tutorials and downloaded sample programs to talk to WSS web services. I realise i have two ways to get items in a list: Use Query() or GetListItems(). Problem is, GetListItems() has a mandatory "Row limit" field and i might have to import ALOT of fields, so i thought Query() is better for me.  But, when using GetListItems(), the WSS returns the ID of the fields (for example, for a field of type user, something like "395;Ivanov Ivan Ivanovich" is returned) but when using Query() for the same list, WSS returns only the field value ("Ivanov Ivan Ivanovich") without the ID. I need it to return the ID as well. How can i set it up, on my side or server side, so i would receive the ID's, not only the values of the fields that are actually linking to something by ID when i use Query() web service?     

MDX query using linked server - performance question

Hi, I'm having a strange performance behavior. When I’m running a mdx query on management studio, it runs for 10 minutes (its mainly calc members on a large cube) When I run the same query via linked server and openquery, it runs for 20 minutes. Is the SQL from some reason does a parsing or running the query twice? The server is sql2008 UP1 on 64bit. and the "allow in process" is checked. its the default in sql2008 Thanks in advance, Yoav  

query w.r.t to SharePoint 2010 Performance Planning & Extranet Topology

  1.      Which extranet topology to go with in case of exposing Intranet to Remote Employees / Partners ?   My understanding:   There are 3 extranet topologies : Edge Firewall , Back to Back , Split back to back   If Scenario is : a)      Only Employees needs to access Intranet from Home ,we can go for Edge Firewall b)      If partners & Employees , both needs to access Intranet ( it will have some partner sites ) , then we can go for Back to Back OR Split back to back .   Questions: ·         Is Understanding correct ? ·         Is there any factor which can help in making a decision between Back to Back Or Split back to back ?   2.      As part of sizing , I read that we should capture following information -          What should be maximum acceptable CPU utilization in production servers ? ( Example : 70%) -          What will be the concurrent number of users accessing portal during peak hour of a day ? ( Example 1000 users from total of 18000 users ) -          How many request per second are done to portal
