Fact Dimension Attribute causing extreme slow query response
I am using SSAS OLAP in SQL Server 2012. My server has 16 GB or RAM - it has only OLAP engine that is being used - nothing related to the relational engine. My fact table has a column called Product Status - for which I've a Fact dimension. Fact table has
18M rows, but the Product Staus has only 2-3 distinct values. When my users bring that attribute in their analysis, the response time is very slow - 10 to 15 minutes. Can anyone share their experiences with how I can go about optimizing this?
I tried to use the user based optimization, but the wizard suggests no aggregations.
Thanks!

Hi GBM,
For a cube of moderate to large size, partitions can greatly improve query performance, load performance, and ease of cube maintenance. Have you define partitions in your cube? Here is a good article regaridng Analysis Services Query Performance Top 10 Best
Practices for your reference, please see:
http://technet.microsoft.com/en-us/library/cc966527.aspx
To troubheshoot MDX query performance issue, we can create a trace to capture some events for further investigation in this case. Please see the articles below how to troubleshoot SSAS MDX query performance issue:

Hope this helps.

SQL tuning for extremely slow query
Hi,
We have a requirement to display sales data by month. The sales data should be summed based on groups. The whole query is dynamically generated so the WHERE clause as well as the GROUP BY columns will be dynamically generated. Please find below the query which has been dynamically generated. The query is extremely slow and is not returning any data even after several minutes.
Please can anyone suggest possible ways of tuning this query? We are evaluating the option of using Materialied Views with Fast Refresh but the number of tables involved in this query runs into several hundreds and creating log in each table would be tedious.
Regards,
Balu

Hi all,
I have an entry here from TKPROF, this is from the production environment. Is there any way that I can make this query run faster?
I would greatly appreciate also if you could explain to me the details of the query below.

ABSI don't have the tables here to test with, but you might verify that this query
select int_basis_desc
, kbr.int_basis_rate
from ( select kib.int_basis_desc
, kbr.int_basis_rate
, max(case when kbr.effect_date <= nvl(:b3,:b4) then kbr.effect_date end)
over (partition by kbr.int_basis) max_effect_date
, effect_date
from fm_int_basis kib
, fm_basis_rate kbr
where kib.int_basis = :b1
and kbr.int_basis = kib.int_basis
and kbr.ccy = :b2
where effect_date = max_effect_date
/gives the same results as the original query.
If still not satisfied, could you paste an explain plan and tkprof output of the new query?

Time capsule causes extremely slow internet
I have an 2011 Apple time capsule running firmware 7.6.4 (latest as far as I know). Recently its begun acting up. Once the modem (a Motorolla SB6121) is restarted and the time capsule is restarted, wifi devices receive the full 100Mbps for approximately 2 minutes. Then the network degrades to hardly 1Mbps. It becomes virtually unusable. With intermittent dropped connections all together. I can confirm its the TC (all is fine on a direct connection from the modem), and I've tried factory resetting TC. The symptoms continue. I've even gotten a new router (it was happening before with a Motorolla SB2100 as well), and the same problem exists.
I'm not sure if its relevant, but it happened around the time Comcast informed us they were increasing our internet speed to about 105Mbps.
Any suggestions?The TC is definitely having issues with the motorola modems..
This one is a bit complicated due to Mavericks.
You can set the WAN port speed on the TC to 100mbit which seems to help for some people.
You can do that using an old fashioned crossover ethernet cable or a small 10/100 switch between the TC and the modem.
In the old utility you can still set the WAN port speed to 100mbit full or half duplex
This is easy to do if you still have a computer running windows, hence older v5 utility.
Mavericks removed the ability to easily run the v5 utility but there is a work around.
http://coreyjmahler.com/2013/10/24/airport-utility-5-6-1-on-os-x-10-9-mavericks/
You must follow those instructions exactly.
No luck then replace the TC as the main router.
Buy a normal standard router.. eg TP-Link WDR3600 which should be around $70. (I pick this one as it can be run on 3rd party firmware like gargoyle which is far more useful than native firmware in most routers). And bridge the TC for use on the network as a WAP and Networked hard disk. -
Morning SQL gurus,
Running queries on APEX takes very long compared to running the script directly on the database.
I tried setting optimizer mode to all_rows, used driving_site and index hints, any other suggestions? The scripts on Apex and DB make use of a db :-/

Pirate

IMac running 10.4.11 Running extremly slow...any suggestions?
I am running my iMac with 10.4.11 and have been experiencing extremely slow program response. I am not very familiar with trouble shooting at all and if anyone has any suggestions I would appreciate it.
Thanks.Hey rt,
I also was very slow with my mac when I wanted to run Tiger. I didnt have any space issues because I have an 80gb external hard drive that I keep everything on except the apps. which the only 3rd party app I have is Photoshop CS, and that was slow whenever I opened a large file to work on. I ran disk repair, etc... and the only solution was to purchase some additional ram being that I was running 256mb. (standard factory) I purchased 512mb (most I can load on user friendly ram slot) from OWC, got the ram the next day installed it, powered up my imac and I immediately noticed my ram was working when the little blue horizontal progress bar on the startup screen zipped across my screen. Now I have photoshop open, multiple tabs in firefox, it's great.
Good Luck

Hi All,
I am sitting on 10.2.0.4.0 on linux box. I've got one complain from the application folks regarding the query the slow query , it's running quite long time. I extracted out the explain plan and commulative wait events for sessions and system and found db file sequenciial read caused us the most waits. the same query was running fine a day before. not sure , where to focus ??

Thanks all of you for your inputs. Well, 2 days back, i logged in as a user , who ran the application query and enabled the level 12 trace and discovered the query never going to complete and press the control-c after 10 min or so and I was left with broken trace file. however , I tkprof'd it and found the "Row Source Operation" and other stuff. now , when I ran the same query it ran in no time and I was start getting the rows in 15 sec of time. I was just unable to figure out ,what had fixed this ? I am also going to past below the comparison stats and hope you guys will able to identify the cause of this behaviour. I tried to do it by comparing the execution plan , but could not able to arrive on any thought. one thing , i would like you to bring into your notice about the fact that while , the bad query were executing (2 days before) , I tried to find out the session waits and discovered , for intiial 5 minutes , it was "SQL*Net message to client ,SQL*Net message from client" and after that it was only "cache buffer chain lru" wait event till i press control-c.
once agian , thanks a lot !!

Airport Extreme Slow Ping (Internet) Response
I am having problems with my dual-band airport extreme. When connecting to the external internet, I'm seeing high ping responses (>500ms) after about 5-10 minutes of resetting (hard reset) the Extreme and initially seeing 15-30ms response times.
I've tried:
1. Moving the router physcially in the house (no improvement)
2. Trying different channels on both 2.5 and 5 (some, but inconsistent improvement)
3. Multiple hard resets and reconfiguring the Extreme
4. Reinstall the firmware (haven't tried going down in firmware)
5. There are no cordless phones in the house
6. Absolute speed to the internet is strong (above my provider's stated speed)
7. If I connect my Macbook pro directly to the cable router, everything (ping + speed) is great.
8. Seeing slow ping responses both on my MacBook Pro and a separate PC
Any suggestions on how to troubleshoot? Seems like it a problem with the wireless connection and/or interference.
thanks!
Dalehad a 5th gen Extreme that I bought with 7.5 and immediately upgraded to 7.6. Saw the exact issue you described. exchanged it for a 6th gen Extreme, and am experiencing the same behavior again... both with 7.5.2 and 7.6 firmware.
everything is hunky dory when plugged directly into my cable modem.
third time's a charm, hopefully. -
SSRS 2008 R2 is extremely slow. The query runs in less than a second in the dataset designer but if you try to view the report it takes over 10 minutes. I have read this is a bug in SSRS 2008 R2. We installed the most recent patches and
service packs. Nothing we've done so far has fixed it and I see that I'm not the only person with this problem. However I don't see any answers either.Hi Kim Sharp,
According to your description that when you view the report it is extremely slow in SSRS 2008 R2 but it is very fast when execute the query in dataset designer, right?
I have tested on my local environment and can‘t reproduce the issue. Obviously, it is the performance issue, rendering performance can be affected by a combination of factors that include hardware, number of concurrent users accessing reports, the amount
of data in a report, design of the report, and output format. If you have parameters in your report which contains many values in the list, the bad performance as you mentioned is an known issue on 2008 R2 and already have the hotfix:
http://support.microsoft.com/kb/2276203
Any issue after applying the update, I recommend you that submit a feedback at https://connect.microsoft.com/SQLServer/
If you don’t have, you can do some action to improve the performance when designing the report. Because how you create and update reports affects how fast the report renders.
Actually, the Report Server ExecutionLog2 view contains reports performance data. You could make use of below query to see where the report processing time is being spent:
After you determine whether the delay time is in data retrieval, report processing, or report rendering:
use ReportServer
SELECT TOP 10 ReportPath,parameters,
TimeDataRetrieval + TimeProcessing + TimeRendering as [total time],
TimeDataRetrieval, TimeProcessing, TimeRendering,
ByteCount, [RowCount],Source, AdditionalInfo
FROM ExecutionLog2
ORDER BY Timestart DESC
Use below methods to help troubleshoot issues according to the above query result :
Troubleshooting Reports: Report Performance
Besides this, you could also follow these articles for more information about this issue:

Using dimension attributes in the Query Builder Bean
All...
I am developing an HTML client based tool using the JSP tags. I wish to create a report that selects the appropriate dimension value based upon an attribute.
But...
Using the query builder I can not select dimension values based upon dimension attributes. Is this possible? The only use I have found for the attributes is when I am sorting my selected diemsnion values.
Thanks in advance
Dylan.1. Java Client QueryBuilder has support for selecting dimension members based on an attribute.
To use this functionality, go to Dimensional Panel -> Conditions tab. Drill on Match group of conditions. The attribute condition appears as the last available condition, but only for dimensions that have attributes.
To test this, use BIBDEMO schema supplied with BI Beans and look at conditions for Product dimension.
2. If you wish to display dimension attributes and their values in the HTML client UI,
here is how you can retrieve attributes and their values for a dimension:
(e.g. for Product dimension in BIBDEMO)
String dimensionID = "MDM!D_BIBDEMO.PRODUCT";
String hierarchyID = null;
MDDimension dimension = metadataManager.getDimensionByUniqueID(dimensionID);
MDHierarchy hierarchy = dimension.getDefaultHierarchy();
if (hierarchy != null)
hierarchyID = hierarchy.getUniqueID();
// Retrieve all the attributes for this dimension
MDAttribute[] attributes = dimension.getAttributes();
if (attributes != null && attributes.length > 0)
String attributeID = null;
AttributeListStep attrStep = null;
Selection sel = null;
MetadataMap map = new MetadataMap(new String[] {MetadataMap.METADATA_VALUE});
for (int i=0; i<attributes.length; i++)
// Get the unique ID for the attribute
attributeID = attributes.getUniqueID();
// Create and evaluate an AttributeListStep
attrStep = new AttributeListStep(dimensionID, hierarchyID, attributeID);
sel = new Selection(dimensionID);
sel.setHierarchy(hierarchyID);
sel.addStep(attrStep);
// Evaluate the AttributeListStep and get the DataAccess
DataAccess da = query.createQueryAccess().getDataAccess(sel, map);
// Walk the DataAccess and get the attribute values
if (da != null)
int extent = da.getEdgeExtent(DataDirector.COLUMN_EDGE);
for (int i=0; i<extent; i++)
// Get the attribute value
strValue = (String)da.getMemberMetadata(DataDirector.COLUMN_EDGE, 0, i, MetadataMap.METDATA_VALUE);
// Add the value to a drop down or another UI element... -
SQL Reporting Services 2014, Enabling Kerberos causes report manager to be extremely slow
We are migrating our environment from SQL Reporting Services 2008 to 2014 on a new server. We are currently using kerberos on the 2008 instance, but when I enable kerberos on the 2014 Reporting Services instance the Report Manager becomes extremely slow.
Has anyone seen this before? Any ideas of what I can check to see what is causing this problem.Just to clarify it is not slow when I run a report, it is slow in general. From first load to accessing a folder, settings, etc. This is all before even executing a report.
The error I see while using Wireshark is KRB Error: KRB5KDC_ERR_BADOPTION NT Status: STATUS_NO_MATCH. When I drill down the into the
error I can see the kerberos string is testprjmnmtreports14.company.com, which is the URL we are using to access the site. I made sure to add that name as an SPN for the service account that is running SQL Reporting Services, however I still receive the error.
Then I tried configuring the site to run without a hostheader, so I accessed the site with the server name ECTSTSQLRS5 and the site works perfectly fine, no errors are reported either. So it seems I have isolated the issue down to Kerberos but I am not sure
how to resolve it. Here is some more information about my environment:
DNS/URL used: testprjmnmtreports14.company.com
Server Name (FQDN): ECTSTSQLRS5.company.int
AD Domain Name: company.int
Server Version: Windows Server 2012 R2
AD Functional Level: 2008 R2
I also have the following SPNs set for my SQL service account:
http/testprjmngmtreports14.company.com
http/testprjmngmtreports14
http/ECTSTSQLRS5.COMPANY.INT
http/ECTSTSQLRS5
As you can see I am trying to use a .com address but my AD domain is .int which I think is the issue, but I do not have the same problem on my other server that is running Windows Server 2008 R2. -
Weblogic 12c Admin Console Extremely Slow Response in "Servers" only
Hi,
I have downloaded and installed weblogic 12c today on IBM p702 blade centre running AIX 7.1 & IBM Java 7. Everything is working fine; Admin Server, Node Manager, etc.
I am facing a strange kind of problem and need your kind suggestions.
When i login to Admin Console 12c and i click on the "servers" link under the domain -> environment; the server response is extremely slow. However, the rest is fine. There is no application deployed and no warning + exception/error is in logs (node manager, admin server out etc.)
Please advice!
Good Day.

Edited by: user1659354 on 11-Jan-2013 03:07This happens when node managers are not running (or not reachable), as it tries to obtain the status of the servers that are deployed on different machines.
What you can check is; are the node managers running on the machines you have configured (in the admin console, click environment, machines, your_machine, monitoring) -
Response time Extremely slow on MS Translator API
Hi,
I am now using Translator API to translate input data from users in real time.
But I found that the response time from the API is sometimes extremely slow.
--- It takes 1 to 2 minute to translate only 5 to 6 characters and it certainly slow down my application
(it normally takes only a few seconds)
--- I am sure that I have enough quota.
I wonder if there is request limit in a minute and if so, how can I upgrade the limit so
I can keep my service work perfectly?
ThanksHi,
This is totally unsusual. For strings in the two to three thousands characters it should not take more than a few 100ms. Can you try again and tell us if you still see this behavior?
Our service is up and running (just go to bing.com/translator and you'll be able to test for yourself the speed of translation for a several hundreds characters sentence) so I'm not sure how to help you out here if it is still the case and your internet
connection is working fine.

Since I upgrade to Firefox 3.5.1 it is extremely slow in responding to lots of web pages including my own home page Atlantic Broadband and my E-Mail for Atlantic Broadband. It just seems to go out to lunch for a minute or more at times. There is no error it eventually gets there, but it is quite annoying. I had no problems at all with the earlier version.
v3.5.1 would be a downgrade because the current version is 4.0
Try updating again, but do it via '''Help '''| '''Check For Updates'''
According to your system specs you currently have v3.6.16 installed which is the previous version to the current one.
