Logical SQL to physical SQL taking time in datamodel.

I am designing a report in BI publisher and for that I am creating a datamodel.
My datamodel contains 4 dataset with 4 different logical SQLs and all use source as Oracle BIEE.
When I generate/execute xml from datamodel I observed in nqquery.log that BI publisher is executing each logical SQL in sequence.
That is OBIEE first send logical SQL of one of the dataset and then convert it to physical SQL. After first physical SQL is completed then only it is converting second logical SQL to physical.
So logical to physical query is happening in sequence rather than in parallel.
My datamodel contains huge logical SQLs and OBIEE takes almost 40 seconds each to convert it physical query. This will result in total 160 seconds for just converting 4 logical SQLs to physical SQLs.
Does anybody know if there is any setting where I can manage to convert multiple logical to physical in parallel?

Hi Experts,
Please help on this.

OBIEE: logical SQL to Physical sql conversion

Hi,
Is there any way i can get the physical sql from logical sql ( Apart from reading log file).. I am looking something like JAVA api which does that for us.. Do we have any mapping table which stores this mapping.
Does the OBIEE provides any Java API.
Appreciate your help in advance.

Difference between logical and physical SQL

Hi all,
I created a dashboard prompt and added some columns from the dimensions and one column from the fact table.
When I run the report in the dashboard and filters using the prompts,I see in the logical sql that all the filters have been applied to the report, but when I check the physical SQL only the filters on the dimensions columns have been applied.
I don't see the filter on the columns from the fact table.
Is there any reason for that?
Regards

I could figure out what was the issue.
My fact table was using a different MV as source table.The fact table column I was using in the prompt was not mapped correctly to the one in the MV.

Converting logical SQL to physical

I have a bunch of logical queries stored in my usage tracking table. What's the easiest way that I can convert these to physical SQL? I want to avoid re-running the reports and looking at the NQQuery.log.
Let me know if there's an easy way to run my logical sql and getting the physical query from it.

Hi,
i) Dashboard -> Click Settings > Administration to open the Oracle BI Presentation Services Administration Window
ii) Click the Manage Sessions link to open the Session Management window.
iii)In the Session Management window, under Cursor Cache, click the View Log link for the last entry.
The log displays the last query.
iv)Locate :
the SQL Request section. This section contains the logical SQL issued from Answers.
the General Query Info section, just below the SQL Request section. This section identifies the repository, subject area, and presentation catalog from which the query was run.
the Sending query to database named SH section, just below the General Query Info section. This section identifies the physical data source to which Oracle BI Server is connecting and the physical sql that was generated.

OBIEE 11g Usage Tracking - Physical SQL

Hi All,
The Query Text column gives me only the logical SQL. The Log Level is set at 2. How can I get the physical SQL via Usage tracking?
Thanks for your time and help.

Hi,
Good for you.
Maybe you can post the solution and how you solved your issue to help other users having the same problem and then close the thread (currently it's still This question is Not Answered.)

[NQQuery log]: Physical SQL generated agaisnt 2 Database in OBIEE 11g

Hi Experts,
I have a problem regarding the physical SQL generated by Query log.
So this is the setup.
SCENARIO 1:
Oracle Data Warehouse DB
- col1
- col2
- col3
OLAP_OBIEE
- col4
When I run these columns together in Analysis. It seems like the physical SQL generated in the Query log is partitioned with each other and I cant get the exact SQL so I can make comparison with the total record count in Analysis UI and the SQL developer.
select col1, col2, col3 from Oracle Data Warehouse tables
select col4 from OLAP_OBIEE tables
================================================================
SCENARIO 2:
Oracle Data Warehouse DB
- col1
- col2
- col3
- col4
Running these columns together in Analysis. I am wondering why the physical SQL is somewhat also partitioned just like in SCENARIO 1.
select col1, col2, col3 from Oracle Data Warehouse tables
select col4 from Oracle Data Warehouse tables
Hope that you get what am I trying to say. :(
Thanks,

Hi Maqsoon,
Sorry for the confusion, in my Analysis report, I have a report where it generates 2 physical SQL in one Database, also I have a report where it uses 2 Database which also generates 2 physical SQL.
Below is the SQl generated in my Analysis report using 1 Database

Based on what you said, so it is impossible to merge the physical SQL if we use 2 Database right?

Logical Reads for a SQL ID

Dear Experts,
Any idea how we can find out Logical reads for a SQL ID over a 24 hour period? AWR shows physical reads info.. any data dictionary view that captures logical I/O?
Thanks

Figured it out.. This is it:
col Time_Taken for 999999999999
col log_reads for 9999999999999
select sql_id, sum(disk_reads_delta) as phy_reads, sum(BUFFER_GETS_DELTA) as log_reads, sum(ELAPSED_TIME_DELTA/1000000) as Time_Taken
from dba_maint.DB_HIST_SQLSTATS
where PARSING_SCHEMA_NAME='USERNAME' and BEGIN_INTERVAL_TIME>='03-JAN-13' and sql_id in ('abcdefghijkl')
group by sql_id order by phy_reads, log_reads, time_taken desc;

Inserting Data from Oracle to SQL Server on the Real Time Basis.

Hi Everyone,
I need to insert data from Oracle to SQL Server on the Real Time basis, we have to fetch data from oracle approx 20 tables, and each table has more than 30 Fields. I need to fetch data in every 15 mins.
I have created a job using SQL SERVER Agent by writing insert queries for all the tables with conditions that no rows will be inserted which is already in SQL. note that this job is taking only 1 min to execute.
But in this way our SQL Server getting hanged and it giving problems to other application running in the SQL SERVER.
So i m requesting all of you that what is the best way to insert huge amount of data on the real time basis.
Thanx in Advance.

1) Create Linked server
2) insert data using openquery and set job in sql agent
3) run job after 15 minutes

Physical SQL Query of the BI Publisher Report

Hi,
Where can we see the Physical SQL Query of the BI Publisher Report with OBIEE as a Data Source? As you people might be knowing, when we chose OBIEE - a logical SQL will/need to be placed.
Thanks,
Vency

I don't see it in NQQuery log:(
Ideally, it should be because it will hit BI Server. Moreover, I can see it (report's logical SQL) in BI Server Cache.
Any other thoughts?

Physical SQL contains apostrophe

In OBIEE-11g, how can we escape apostrophe in physical SQL. For example a filter that contains member name(Amy O'Brien) is being sent as 'where member_name ='Amy O''''Brien'. The four quotes are leading to mismatch of the conditiona and hence not returning any results.
Thanks

Logic Doubling in v7 SQL - Dimension with 3 hierarchies

I'm having a problem with logic doubling at a client where I have a dimension with 3 hierarchies in v7 SQL 2008. When I try to run logic off a property in this dimension, base members in all 3 hierarchies are doubling, whereas base members in only two hierarchies are not. I've tried using *Membersets, *Select, and *XDIM_Memberset statements to stop the values from doubling, but I'm not having success.
Any ideas? Has anyone else seen this?
Thank you,
Grant

Yes, sorry, I've been busy.
Basically, I had two rollups of data in one dimension, and when I was trying to reconcile the logic push that consolidated all the data from this dimension into one member, I was only looking at one of the rollups, and not the other one. So, it was really just a matter of writing logic and running it without taking into account all the data I was manipulating.
Thanks,
Grant

Moving Physical SQL Cluster into Virtual SQL Cluster based on Hyper-V Failover

Hello All............I have a SQL Cluster based on Physical Hardware that has Three-3 instances as well. I have setup a Hyper-V Failover Cluster (2012 R2) and have built Virtual/Guest SQL Cluster (2012 R2) upon it. Now, I intend to move
the instances/databases from Physical SQL Cluster to Virtual SQL Cluster.
1. Is this supported? If so, I would appreciate any guidance on it?
2. Is P2V of SQL Cluster supported in Hyper-V Failover Cluster based on Windows Server 2012 R2?

Hi Sir,
Please refer to the following blog regarding moving SCCVM SQL database to another SQL server:
http://blogs.technet.com/b/configurationmgr/archive/2013/04/02/how-to-move-the-configmgr-2012-site-database-to-a-new-sql-server.aspx
It is quoted from the similar thread :

But it seems that is a migration of system center production , I would suggest you to post the question to system center forum ：
