"Determining Query Time Estimate" takes long time.

Is there any way we can turn it off? Actually query takes few seconds but it takes almost five minutes to determining time estimate.
Does anybody know why it happens?
Thanks in advance
Naveen

edit preferences and set QPPEnable to zero.
Then apply the preferences.
This should turn off query prediction.

Query on Cube jumps to Query on ODS ; Query on ODS takes Long time

Hi All,
Perormance Issue: Query on Cube jumps to Query on ODS.
Query on ODS taking long time.(JumpQuery)
Specific to ODS Query: When i have checked the Query on ODS(individually) also taking longer time
Actually ODS contains quite huge data. Indexes already maintained.
I have checked the RSRT- Execute SQL and Debug Option also. Indexes maintained Perfectly .
Order of objects in ODS indexes are matching the order of Objects in SQL stat of RSRT Trans. Inspite of that taking long time.
I have checked both the ways jumpquery aswellas individually .
My question is when the query is jumping from cube to query on ODS how to check the performance, how the query is executing in background when switching over to the second query, Moreover calculated keyfigure has been used for jumping to the target query.
How can query(ods query) time is optimized or improve performance when jumping from query on Cube ?
can any body help?
Rgds,
C.V.

What i understand is that you need to optimise the Query jumping time . But this will be very less compared to the time taken by the query on the ODS.
Ideally you shouldnt be making a BEx Query on the ODS , as this takes a long time. What you can do is try executing the Bex Query on the ODS to find out as to where the issue lies. If this query is taking a long time , there is not muich that you can do here.

BEx query selection screen takes long time to popup

Hi,
I have a query which is taking long time to popup the selection screen. I have tried in RSRT the generate report option, the generating report takes 45 to 60 mins. After the report is generated the query selection screen comes up in couple of seconds. The first time I run the query everything its fine but then for the second time the problem comes back again.
The selection screen takes +/- 40 mins to comes up in RSRT and in the portal it times out.
I have run the statistics of the query and according to the statistics report the query takes a lot of time for the following component :
OLAP: Query Gen. 2681,312682
I have removed the query from the cache monitor and after that regenerate the report. But these steps didnu2019t solve my problem.
I made two test queries, in one query I have made the CKFu2019s and RKFu2019s directly at the infoprovider, and dragged and dropped in the KF structure. In the other query I made the CKFu2019s and RKFu2019s in the query KF structure itself. The query where I have the CKFu2019s and RKFu2019s at the infoprovider that query times out, the other query where I put the CKFu2019s and RKFu2019s in the query KF structure doesn't has this performance problem.
What I donu2019t know is why the query is failing when I use RKFu2019s and CKFu2019s from the infoprovider, the other query donu2019t have this problem.
Please advise how to proceed.
Thanks in advance,

Hi,
Please check the following notes which should be useful.
1387593 - Performance optimization for query change/generation
1416737 - Performance optimization for query change/generation(2)

Drop Down List in Query Selection Screen Takes Long Time.

I open a report, refresh the query and get a selection screen. But when clicked on the drop down list it takes 4- 5 mins for displaying the drop down options.
How can I speed up the displaying of drop down list in selection screen?
Could any one please help regarding the setting to enable this?
Thanks.

Hi,
I guess there is a setting to look up the master data tables or use the dimension,which would speed up the time that it takes to display the drop down selections
Do you have any idea about the setting?
Thanks.

Query Prediction takes long time - After upgrade DB 9i to 10g

Hi all, Thanks for all your help.
we've got an issue in Discoverer, we are using Discoverer10g (10.1.2.2) with APPS and recently we upgraded Oracle DatBase from 9i to 10g.
After Database upgrade, when we try to run reports in Discoverer plus taking long time for query prediction than used to be(double/triple), only for query prediction taking long time andthen takes for running query.
Have anyone got this kind of issues seen before, could you share your ideas/thoughts that way i can ask DBA or sysadmin to change any settings at Discoverer server side
Thanks in advance
skat

Hi skat
Did you also upgrade your Discoverer from 9i to 10g or did you always have 10g?
If you weren't always on 10g, take a look inside the EUL5_QPP_STATS table by running SELECT COUNT(*) FROM EUL5_QPP_STATS on both the old and new systems
I suspect you may well find that there are far more records in the old system than the new one. What this table stores is the statistics for the queries that have been run before. Using those statistics is how Discoverer can estimate how long queries will take to run. If you have few statistics then for some time Discoverer will not know how long previous queries will take. Also, the statistics table used by 9i is incompatible with the one used by 10g so you can't just copy them over, just in case you were thinking about it.
Personally, unless you absolutely rely on it, I would turn the query predictor off. You do this by editing your PREF.TXT (located on the middle tier server at $ORACLE_HOME\Discoverer|util) and change the value of QPPEnable to 0. AFter you have done this you need to run the Applypreferences script located in the same folder and then stop and start your Discoverer service. From that point on queries will no longer try to predict how long they will take and they will just start running.
There is something else to check. Please run a query and look at the SQL. Do you by change see a database hint called NOREWRITE? If you do then this will also cause poor performance. Should you see this let me know and I will let you know how to override it.
If you have always been on 10g and you have only upgraded your database it could be that you have not generated your database statistics for the tables that Discoverer is using. You will need to speak with your DBA to see about having the statistics generated. Without statistics, the query predictor will be very, very slow.
Best wishes

CV04N takes long time to process select query on DRAT table

Hello Team,
While using CV04N to display DIR's, it takes long time to process select query on DRAT table. This query includes all the key fields. Any idea as to how to analyse this?
Thanks and best regards,

Be aware that XP takes approx 1gb of your RAM leaving you with 1gb for whatever else is running. MS Outlook is also a memory hog.
To check Virtual Memory Settings:
Control Panel -> System
System Properties -> Advanced Tab -> Performance Settings
Performance Options -> Adavanced Tab - Virtual Memory section
Virtual Memory -
what are
* Initial Size
* Maximum Size
In a presentation at one of the Hyperion conferences years ago, Mark Ostroff suggested that the initial be set to the same as Max. (Max is typically 2x physical RAM)
These changes may provide some improvement.

Reason and Prerequisites
The authorizations below are not assigned to the user.
Solution
Assign authorization for roles
To assign authorizations for a role, execute the following steps:
1. Start Transaction Role maintenance (PFCG)
2. Select a role
3. Choose the "Change" switch
4. Choose tab title "Authorizations"
5. Choose the "Change authorization data" switch
6. Choose "+ Manually" switch
7. Enter "S_USER_AGR" as "Authorization object"
8. Expand "Basis: Administration"/"Authorization: Role check""
9. From "Activity" select "Create or generate" and others like "Display" or "Change"
10. Under "Role Name", enter all roles that are supposed to be shown or changed. Enter "*" for all roles.
11. You can re-enter authorization object "S_USER_AGR" for other activities.
Assign authorization for transactions
If a user is granted the authorization for changing a role, he/she should also be granted the authorization for all transactions contained in the role. Add these transaction codes to authorization object S_USER_TCD.
1. Start the role maintenance transaction (PFCG).
2. Select a role.
3. Click on "Change".
4. Choose the "Authorizations" tab.
5. Click on "Change authorization data".
6. Click on "+ manually".
7. Specify "S_USER_TCD" as "Authorization object".
8. Expand "Basis - Administration"/"Authorizations: Transactions in Roles".
9. Under "Transaction", choose at least "RRMX" (for BW reports), "SAP_BW_TEMPLATE" (for BW Web Templates), "SAP_BW_QUERY" (for BW Queries and/or "SAP_BW_CRYSTAL" (for Crystal reports) or "*". Values with "SAP_BW_..." are not transactions, they are special node types (see transaction code NODE_TYPE_DEFINITION).
Using the SAP System Trace (Transaction ST01), you can identify the transaction that causes NOT_AUTHORIZED.
Prevent user assignment
Having the authorization for changing roles, the user is not only able to change the menu but also to assign users. If you want to prevent the latter, the user must loose the authorization for Transactions User Maintenance (SU01) and Role maintenance (PFCG).
Z1>Note
Refer to Note 197601, which provides information on the different display of BEx Browser, BEx Analyzer and Easy Access menu.
Please refer to Note 373979 about authorizations to save workbooks.
Check in the transaction ST22 for more details on the Query designer failure or query log file.

MVIEW refresh takes long time

Materialized view takes long time to refresh but when i tried select & insert into table it's very fast.
i executed SQL and it takes ust 1min ( total rows is 447 )
but while i refresh the MVIEW it takes 1.5 hrs ( total rows is 447 )
MVIEW configration :-
CREATE MATERIALIZED VIEW EVAL.EVALSEARCH_PRV_LWC
TABLESPACE EVAL_T_S_01
NOCACHE
NOLOGGING
NOCOMPRESS
NOPARALLEL
BUILD DEFERRED
REFRESH FORCE ON DEMAND
WITH PRIMARY KEY
Not sure why so much diffrence

A MV refresh does that and also writes database data.
These are not the same thing and cannot be directly compared.
So instead of pointing at the SELECT execution time and asking why the MV refresh is not as fast, look instead WHAT the refresh is doing and HOW it is doing that.
Is the execution plan sane? What events are the top ones for the MV refresh? What are the wait states that contributes most to the processing time of the refresh?
You cannot use the SELECT statement's execution time as a direct comparison metric. The work done by the refresh is more than the work done by the SELECT. You need to determine exactly what work is done by the refresh and whether that work is done in a reasonable time, and how other sessions are impacting the refresh (it could very well be blocked by another session).

"Determining Query Time Estimate" takes long time.
