Report performance Issue in BI Answers

Hi All,
We have a performance issues with reports. Report is running more than 10 mins. we took query from the session log and ran it in database, at that time it took not more than 2 mins. We have verified proper indexes on the where clause columns.
Could any once suggest to improve the performance in BI answers?
Thanks in advance,

I hope you dont have many case statements and complex calculations that you do in the Answers.
Next thing you need to monitor is how many rows of data that you are trying to retrieve from the query. If the volume is huge then it takes time to do the formatting on the Answers as you are going to dump huge volumes of data. Database(like teradata) returns initially like 1-2000 records if you hit show all records then even db is gonna fair amount of time if you are dumping many records
hope it helps
thanks

Report Performance Issue - Activity

Hi gurus,
I'm developing an Activity report using Transactional database (Online real time object).
the purpose of the report is to list down all contacts related activities and activities NOT related to Contact by activity owner (user id).
In order to fullfill that requirment I've created 2 report
1) All Activities related to Contact -- Report A
pull in Acitivity ID , Activity Type, Status, Contact ID
2) All Activities not related to Contact UNION All Activities related to Contact (Base report) -- Report B
to get the list of activities not related to contact i'm using Advanced filter based on result of another request which is I think is the part that slow down the query.
<Activity ID not equal to any Activity ID in Report B>
Anyone encountered performance issue due to the advanced filter in analytic before?
any input is really appriciated
Thanks in advanced,
Fina

Fina,
Union is always the last option. If you can get all record in one report, do not use union.
since all records, which you are targeting, are in the activity subject area, it is not nessecery to combine reports. add a column with the following logic
if contact id is null (or = 'Unspecified') then owner name else contact name
Hopefully, this is helping.

Accrual Reconciliation Load Run report performance issue.

we have significant performance issues when running accrual reconciliation load run report. we had to cancel after have it run for a day. any idea on how to resolve it?

We experienced similar issue. As the runtime of this report depends on the input parameters. Remember, your first run of this report going to take significant amount of time and the subsequent runs will be much shorter.
But w had to apply the patches referred in the MOS article to resolve the performance issue.

HR ABAP- Report Performance Issue

Can you please any body tell me how to debug a report program by putting watch points and break points.
Waiting for your Reply.
Anu
Bangalore

Hi,
           If you have programm name then proceed with SE38 or take the programm name from Trasaction code which you are using.
Break Points:   If it is performance issue , put external break points around select querie and loop ---end loop.
Watch Points : in the debug screen choose the watch point option and give the field name from your internal table for which you want to put watch point.
After that give the range which you record you want to see in the range options.
for these steps: 1. Execute your programm.
       2. In the selection screen enter /h in the command window to start debugging screen or put break points before excuting.
     3. Once you are in debug screen then start woring with F5 or F6 or F7 and create watch points where ever you like.

Hi
i also faced such an issue and then i found the answer on metalink
Error: "An Interactive Reporting Service Error has Occurred. Failed to Acquire Requested Service. Error Code: 2001" when Processing a bqy Report in Workspace. [ID 1117395.1]
Applies to:
Hyperion BI+ - Version: 11.1.1.2.00 and later [Release: 11.1 and later ]
Information in this document applies to any platform.
Symptoms
Obtaining the following error when trying to process a BQY that uses an Essbase data source in Workspace:
"An Interactive Reporting Service error has occurred. Failed to acquire requested service. Error Code: 2001".
Cause
The name of the data source in the CMC contained the machine name in fully qualified name format whereas the OCE contained the machine name only. This mismatch in machine names caused the problem. Making the machine name identical in both cases resolved the problem.
Solution
Ensure that the name of the data source as specified in the OCE in Interactive Reporting Studio matches the name specified in the CMC tool in the field "Enter the name of the data source".
In fact, all fields need to match between the OCE and the CMC Data Source.

Deski reports performance issue

After an upgrade from BOXI Release2-SP3 to BOXI Release3.1-SP3 all the deski reports are very slow when we try to refresh them using Infoview.
For example, a specific deski report needs two minutes from Desktop Intelligence and twenty!!! minutes from Infoview. The same behavior have all the migrated deski reports. Do you have any idea/workaround??

XL Report performance issues

Hello All,
We are running some XL reports and facing some performance issues: 10 mins for a report to run.
We don´t plan to split this report in many other ones, and I have already run the SQL tools for reorganizing and reindexing the tables (I believe this is nothing to do with performance but ran it anyway...) without any improvements.
Can anybody be a help on this?
Thanks!

Hi Siavauch Saleki
Name the report which take too long to run, i have worked on XL report, when i run report from client system it takes some long time,
try running to run from server
another way of making it faster is go to Task manager in the process tab
Change the priority of XL Reporter , excel to HIGH
THIS WILL MAKE IT FASTER BY ALLOCATING MORE PROCESSOR TIME FROM OS TO IT
This should improve the reporting speed
Let me know how it works
Regards

Webi Reports - Performance Issues

Hi Experts,
       Right now we are using BO XI R2 version. We have 2 servers, server 1 is old and server 2 is new (AIX server u2013 new upgrade of old server).
      When I trying to schedule the report (webi) in both server, reports is running successfully. But problem is that the report scheduling time is more in new server (AIX) than old server (Server1).
There is some performance issues
Example:
Old serve     : 1 hrs (time taken)
New server : 2 hrs (time taken)
Could you please tell me how to increase the webi report performance in new server?

FRS report performance issue

Hello,
We have a report developed in FRS in the below style.
http://postimg.org/image/bn9dt630h/b9c2053d/
Basically, all the dimensions are asked in POV. In the rows of the reports, we have two sparse dimensions that are drilled down to level 0 as shows in above report. The report works fine when run in local currency (Local currency is a stored member). When the report runs in a different currency (dynamic member) then it keeps on running for ages. We waited for 45 minutes and then had to cancel a report, when the same was run in local currency, it gave us our results in 30 seconds.
My thinking is that there should be a better way of showing level 0 members than using "Descendants of Current Point of View for Total_Entity AND System-defined member list Lev0,Entity" as I presume what it does is get descendants as well as level0 members and then compare them. I have alternate hierarchies hence I am using this, isn't there a simple way of saying - just give me level 0 members of the member selected in POV ?
I have used below parameters
Connection - Essbase
Suppress rows on Database connection server
Regards,

Hello,
>> The report works fine when run in local currency (Local currency is a stored member). When the report runs in a different currency (dynamic member) then it keeps on running for ages.
You are focusing on the report. The most likely reason is in the performance of the database. Ofcourse, you can reduce the query size and get your report performing again, but the root cause is likely the database design.
I do not know a function to drill down to the level0 members of the selected POV member.
If this is something different per user, then you might think about meta-read filters. They would remove all that is not granted.

2014 SSRS Reports Performance issues

Hi All,
After upgrading SQL 2008 reports to SQL 2014 i observed there is performance lag in 2014 ssrs reports,
2008 reports which used to render in <2 secs now taking >50 secs,
After doing some checks on why this lag occurred, i found that this is because of the expressions in reports, If i remove all the expressions then report renders < 2 secs otherwise its taking >50 secs
My question here is, we used the same expressions in 2008 version also which displays the report in <2 secs but why same thing taking more time in 2014 version.
Is expressions handling in 2008 and 2014 different.
and below are the expressions used in the both the versions
IIF(ISNOTHING(Fields!Comp.Value),"-",Fields!Comp.Value)
IIF(ISNOTHING(Fields!Base.Value),"-",Fields!Base.Value)
IIF(ISNOTHING(Fields!Var.Value),"-",Fields!Var.Value)
iif(Fields!check.Value=true,"yellow","Transparent")
Thanks in advance
Chandra.

Hi Chandra,
According to your description, the same report render slower in SQL Server 2014 than in SQL Server 2008.
In both SSRS 2008 and SSRS 2014, the expression is processed in the same way. In Reporting Services, the total time to generate a report include TimeDataRetreval, TimeProcessing and TimeRendering. To analyze which section take much time, we can check the
table Executionlog3 in the ReportServer database. For more information, Please refer to this article:
More tips to improve performance of SSRS reports.
After check out which section costs most of time, then you can refer to this article to optimize your report:
Troubleshooting Reports: Report Performance.
If possible, please share some information about your report migration.

SQL Server 2000 std Report Performance Issue

Dear All,
I have a VB based desktop application with back end MS SQL server 2000 database with server machine ibmx5650 with specs intel xeon 2.7GHz (24 CPU's) & 24GB RAM.
There are two things i need help:
Recently we have upgrade the SQL server from 2000 personal edition to the 2000 standard edition. There comes a problem with one of the Report in the application. The report took almost 30 mins previously in SQL 2000 personal edition.But after the upgrade
to Standard edition we are unable to view report before 3 hours even sometimes it doesn't appear after several hours.
Secondly for brief testing i have installed the personal edition on a simple PC rather then a server PC specs are corei5 & 4 GB of RAM. The same report is generated in only 15 mins from the application with this desktop machine as DB server.
Please help me out i have gone through all SQL Server & system performance log of my server machine everything is normal but the report is taking too long & i can only generate that report from personal edition.
Is there the difference due the higher corei5 processor in desktop machine or there is any other issue behind this.
Your prompt response is highly appreciated.
Regards,
Rashid Ali

Hello,
SQL Server 2000 is not support since 2013. Please upgrade to SQL Server 2012 to get better performance and support.

Webi Report Performance issue as compared with backaend SAP BW as

Hi
We are having Backend as SAP BW.
Dashboard and Webi reports are created with Backend SAP BW.
i.e thru Universe on top of Bex query and then webi report and then dashboard thru live office.
My point is that when we have created webi reprts with date range as parameter(sometimes as mandatory variable which comes as prompt in webi) or sometimes taking L 01 Calender date from Bex and creating a prompt in webi, we are facing that reports are taking lot of time to open. 5 minutes 10 minutes and sometimes 22 minutes to open.
This type of problem never ocurred when Backened was Oracle.
Also when drilling in webi report,it takes lot of time .
So can you suggest any solution?

Hi Gaurav,
We logged this issue with support already, it is acknowledged.
What happens is that whenever you use an infoobject in the condition
(so pull in the object into condition and build a condition there,
or use that object in a filter object in the universe and then use the filter)
this will result in that object being added to the result set.
Since the query will retrieve a lot of different calendar days for the period you selected,
the resultset will be VERY big and performance virtually non-existent.
The workaround we used is to use a BEX variable for all date based selections.
One optional range variable makes it possible to build various types of selections
(less (with a very early startdate), greater (with a very far in the future enddate) and between).
Because the range selection is now handled by BEX, the calendar day will not be part of the selection...
Good luck!
Marianne

We have a custom report that is a modified version of the seeded report, and we cannot run the report to completion since our last round of patching. Patches applied are listed below, and include YE Phase 2.
We have not yet opened a TAR on this, because we'll need to gather some information internally first.
Thanks,

We've hit the performance bug and logged an SR. We ran the shipped report and it chugged for 2 1/2 days then blew up on snapshot too old. If you can avoid that error then it fails with ORA-01722: invalid number. I defragged and analyzed the Payroll tables and indexes but it's not enough to help the bad code. I think part of the issue is that the report code just uses a generic /*+ RULE */ hint. Another part of the issue may be that NULLs in the payroll tables aren't properly accounted for in the code.
The behavior of the 'RULE' hint seems to be dependent on what the Paryoll LOW_VOLUME parameter is set to. That is, with LOW_VOLUME=Y and small tables the 'RULE' hint might be fine, but in the real World with with LOW_VOLUME=YouGottaBeKidding it doesn't.
The new Payroll Activity Report for the whole year has very good performance--it only took 4 hours in our environment--and it used to take days.
Open an SR and ask to be attached to Bug 5742521.

Interactive Reports - Performance Issue

Hi All
We have been getting ORA-04030: out of process memory … more and more frequently since first implementing Interactive Reports. From Enterprise Manager we had a look at the most costly queries and the one that stands out the most is:
SELECT *
FROM WWV_FLOW_WORKSHEET_CONDITIONS
WHERE CONDITION_TYPE = ‘HIGHLIGHT’
AND WORKSHEET_ID = :B2
AND SECURITY_GROUP_ID = :B1
ORDER BY HIGHLIGHT_SEQUENCE, NAME I have done all I can with the memory configuration and we are in the process of upgrading the servers to 64 bit Linux.
However, I noticed that WWV_FLOW_WORKSHEET_CONDITIONS table has 400,000 rows and the above query is performing a full table scan on it. As the query is run each time an IR report is viewed, this could account for the problems. The DBAs are of the opinion that the indexing and query are optimal and cannot be improved, so the obvious solution is to archive and purge the table.
Of the 400k rows, 80% are session values linked to sessions that no longer exists. It would appear that each time a user adds a filter or highlight to an interactive report it is recorded as a session value in the WWV_FLOW_WORKSHEET_CONDITIONS table. When the user logs out and closes the session, the values remain in the table and aren't cleared!!!? We currently average about 90 users a day with 60,000+ page requests so 400,000 rows is way more than I would expect to see.
Am I missing something? How do redundant session values get purged from the ir flows tables? Is there a (supported) way for me to clear them?
This is a critical issue for me now and I have raised an SR on metalink, but if the forum could offer some advice or assistance it would be very much appreciated.
Cheers
Simon

Hi Varad
Thanks for your help. I have had a good play with the purge function and now I'm more confused than ever. First let me explain my test scenario: I have an application with an interactive report in which I am logged in and able to make session changes (without saving the reports). I am observing the session activity on the Interactive Report using the apex_application_page_ir_rpt view which is set to filter on the application and page number for the Interactive Report I am testing.
Test 1
User logs into application, adds a filter to the report.
Result: A new row appears in the apex_application_page_ir_rpt view
Administrator Purges all sessions > 10secs old
Result: The new row is removed from apex_application_page_ir_rpt view
Test 2
User logs into application, adds a filter to the report.
Result: A new row appears in the apex_application_page_ir_rpt view
User logs out of application
Result: The new row remains in the apex_application_page_ir_rpt view
Administrator Purges all sessions > 10 secs old
Result: The new row still remains in the apex_application_page_ir_rpt view view
I hope that makes sense. Why would the session values not be cleared if the user logs out first? Why are they not then cleared if all the sessions are purged?
I am hoping that someone else can repeat the test and see if they find the same result.
Cheers
Simon
