NiUsrp Fetch Rx data band

Hi all,
the "niUsrp Fetch Rx data.vi" does output signal in baseband or in the carrier frequency set-up by the "niUSRP Configure Signal.vi"?
I will use it to make a mixer "via software", in radar application, and I have to know if the correct way for mixing Tx and Rx signals is to take directly the output of the "niUsrp Fetch Rx data.vi" or if I should downconvert this signal.
Thanks,
Giube

Hi Giube,
have you tried with the example you can find in LabVIEW? There are a couple that come up when you search for DDC, but the most appropriate for your case is probably the "niScope EX OSP Downconversion.vi.
Let me know if that can work out for you!

Error -1074118610 occurred at niUSRP Fetch Rx Data (CDB Cluster).vi

I researched this error in forum ,however, I don't reach the solutions.
Error -1074118610 occurred at niUSRP Fetch Rx Data (CDB Cluster).vi
The received data is out of sequence. This may be a symptom of overflows due to an inability to maintain streaming at the specified IQ Rate, or rearrangement of packets by an ethernet adapter or network switch.
When I start to USRP, I am taking this error 6-7 minutes later. I tried IQ Rate= 2M and samples per symbol=4 also IQ Rate is approximately 192k and samples per symbol= 20 for 9600 baud rate.

Hello ITUbahadir
I understand you are NOT testing a LabVIEW shipping example. If this is correct, Could you try to test the shipping examples? Same error? If this is incorrect, what is the name of the example?
If the problem is specific to your code, could you share it? If you are not able to do that, could you explain me what have you changed to the code?

Data sequence to niUSRP write Tx Data

Hay all,
Currently, I'm trying to develop 802.15.4 system. I have a few question about the data sequence that being fetched into niUSRP write Tx Data.vi.
The vi (niUSRP write Tx Data) accepts IQ data from modulation block, What is the sequence for data that is being transmitted? For example, bitstream is modeled as array, which array[] is tranmitted first? The LSB, or the MSB.
The standard itself (802.15.4) specify that the least bit (C0) is transmitted first.
Thank you.

my TICC2530 has been sucessfully detected the signal, but the decoding still messy.
And I have problew, because
"niUSRP Write Tx Data (CDB Cluster).vi<ERR>Underflow: the Tx buffer was emptied before new data was provided. Consider reducing the IQ rate, increasing the Write rate, or increasing the number of samples per Write."
I already tried to change the registry, as mentioned in here Increasing-write-rate , but, I still have the problem, when I run the IQ rate > 4M and samples per symbol 4. Hence, the CC2530 won't recognize the signal, if I set the IQ rate to be 4M. This in the constelation for my custom OQPSK half sine pulse (4M, 4samples/symbol, Symbol rate 1M)
and my CC2530 will recognize the signal if I set the IQ rate 8M and samples per symbol 8, here is the constelation diagram
So, my question is, how to handle the error?

Not able to fetch the data by Virtual Cube

Hi Experts,
My requirement is I need to fetch the data from Source System (From Data base table) by using Virtual Cube.
What I have done is I have created Virtual Cube and created corresponding Function Module in Source System.
That Function MOdule is working fine, if Data base table is small in Source System.But If data base table contains huge amount of data (millions of record), I am not able to fetch the data.
Below is the code I have incorporated in my function module.
c_th_mapping TYPE CL_RSDRV_EXTERNAL_IPROV_SRV=>TN_TH_IOBJ_FLD_MAPPING.
DATA:
    l_s_map TYPE CL_RSDRV_EXTERNAL_IPROV_SRV=>TN_S_IOBJ_FLD_MAPPING.
l_s_map-iobjnm = '0PARTNER'.
l_s_map-fldnm = 'PARTNER'.
insert l_s_map into table l_th_mapping.
create object l_r_srv
    exporting
       i_tablnm              = '/SAPSLL/V_BLBP'
      i_th_iobj_fld_mapping = l_th_mapping.
l_r_srv->open_cursor(
    i_t_characteristics = characteristics[]
    i_t_keyfigures      = keyfigures[]
    i_t_selection       = selection[] ).
   l_r_srv->fetch_pack_data(
    importing
      e_t_data = data[] ).
return-type = 'S'.
In the above function Module,Internal table L_TH_MAPPING contains Info Objects from Virtual Cube and corresponding field from Underlying data base table.
The problem where I am facing is, in the method FETCH_PACK_DATA, initially program is trying to fetch all the recordsfrom data base table to internal table.If Data base table so lagre, this logic is not working.
So would you please help me how to handle these kind of issues.

How to fetch the data from pl/sql table dynamically

Hi All, I have the requirement of comparing two db views data in pl/sql. So, I have bulk collect the view into pl/sql table. But, the issue is, It is expecting to provide the column name for comparison. But, in my case, column name is dynamic. So, i cannot provide the column name directly for comparison.
For eg: In my view t1_VW, i have 4 columns. stid, c1,c2,c3,c4 and similar structure for t2_vw
my code
TYPE v1_type IS TABLE OF t1_vw%ROWTYPE;
l_data v1_type;
TYPE v1_type1 IS TABLE OF t2_vw%ROWTYPE;
l_data1 v1_type1;
test varchar2(1000);
test1 varchar2(1000);
temp1 number;
begin
SELECT * Bulk collect into l_data
FROM T1_VW;
SELECT * Bulk collect into l_data1
FROM T2_VW;
select l_data(1).stid into temp1 from dual; -- It is working fine and gives me the value properly
-- But, in my case, we are reading the column names from array, i am constructing the query dynamically and execute it.
test :='select l_data(1).stid into temp1 from dual';
execute immediate test into temp1;
-- I am getting error as follows:
Error report:
ORA-00904: "L_DATA": invalid identifier
ORA-06512: at "SYSTEM.BULKCOMPARISON", line 93
ORA-06512: at line 2
00904. 00000 - "%s: invalid identifier"
*Cause:
*Action
end;
- Please help me to get rid of this issue. Is it possible to construct the query dynamically and fetch the data?. If not, is there any other better approach to compare the data between two views?.

Output should display what are all columns changed and its old value and new value.
For eg., output should be
COLUMNNAME OLD_VALUE NEW_VALUE STID
C1 20 10 1
C2 50 40 2
C3 60 70 2
C2 80 90 3Why no do this only via a simple sql ?
create table a (STID number, C1 number, C2 number, C3 number);
insert into a values (1, 20, 30, 40)
insert into a values (2, 40, 50, 60);
insert into a values (3, 90, 80, 100);
create table b as select *
from a where 1 = 0;
insert into b values (1, 10, 30, 40)
insert into b values (2, 40, 40, 70);
insert into b values (3, 90, 90, 100);
commit;And now you can issue such a kind of select
SELECT stid , c1, c2, c3
   FROM
( SELECT a.*,
         1 src1,
         to_number(null) src2
   FROM a
   UNION ALL
   SELECT b.*,
         to_number(null) src1,
         2 src2
    FROM b
   GROUP BY stid , c1, c2, c3
   HAVING count(src1) <> count(src2)
   order by stid;I would then create a new table a_b_difference having the same structure as a or b and insert into it like this
create table a_b_diff as select * from a where 1 = 0;
insert into a_b_diff
SELECT stid , c1, c2, c3
   FROM
( SELECT a.*,
         1 src1,
         to_number(null) src2
   FROM a
   UNION ALL
   SELECT b.*,
         to_number(null) src1,
         2 src2
    FROM b
   GROUP BY stid , c1, c2, c3
   HAVING count(src1) <> count(src2)
   order by stid
   ;Then each time there is a difference between a column in a and its equivalente one in b (per unique stid ) a record will be inserted in this table.
You can do more by adding the name of the table in front of each record in this table to see exactly where the data comes from

How to fetch the data from databse table and get the required output

Hi,
I have made a project that connects CEP to database table but i m getting some problem in fetching the data from database.
From the following code :
If the where condition is removed then the application runs fine but i am still not able to fetch the data from the table because it is not showing any output.
Can anyone please suggest me that how to write WHERE statement correctly and how i will be able to see the output.

Do you have StockDs configured in your server config.xml?
I think the query should look more like this:
SELECT stocks.SYMBOL, stocks.EXCHANGE
FROM STOCK as stocks, ExchangeStream [Now] as datastream WHERE stocks.SYMBOL = datastream.SYMBOL

How to Fetch the Data from a Cube

Dear All,
We created a cube containing dimensions
Customer, Product, Branch, Activity, Time dimensions
using Oracle Analytical WorkSpace Manager.
Once Cube is created,
How can I see the Data existing in the Cube using normal SQL Queries ??? Through Analytical Workspace Manager Toll we r able to see the data. But our requirement is to see the data from the Cube using SQL Queries.
Regards,
S.Vamsi Krishna

Hey I got the Solution. It follows in this way :
A Cube is nothing but a Data Storage. Based on the Mapping we given it considers the data.
To fetch the data from the Cube -> we have to write the SQl Query as below :
     SELECT dealer_name,model_name,sales
     FROM TABLE(OLAP_TABLE('MDB.FINAL_AW DURATION SESSION',
     'DIMENSION dealer_name AS varchar2(30) FROM FINALDEAL
     DIMENSION model_name AS varchar2(30) FROM FINALMODEL'));
We can create View for the above statement o
we can apply group by ,rollup, etc etc clauses
and even we can write where clauses for the above select statement.
But now my doubt is :
can we apply any calculations while mapping the Level to an Dimension.
Generally we will map Level toa dimension as DBUSER.TABLENAME.COLUMN NAME
can we apply any calculation like :
MIS.PROPKEY020MB.MATURITY_DATE+2
Please help for the above.
If any wrong is there please let me know
Regards,
S.Vamsi Krishna
can we apply

Report is not fetching the data from Aggregate..

Hi All,
I am facing the problem in aggregates..
For example when i am running the report using Tcode RSRT2, the BW report is not fetching the data from Aggregates.. instead going into the aggregate it is scanning whole cube Data....
FYI.. Checked the characteristcis is exactely matching with aggregates..
and also it is giving the message as:
<b>Characteristic 0G_CWWPTY is compressed but is not in the aggregate/query</b>
Can some body explain me about this error message.. pls let me know solution asap..
Thankyou in advance.
With regards,
Hari

Hi
Deactivate the aggregates and then rebuild the indexes and then activate the aggregates again.

How to fetch the data from a pl/sql table and varray, with some example

I want to fetch the data using a cursor from Pl/sql table and varry and I want to update the data.
Please provide me some example.

PL/SQL Table - please note that, right term is Associative Array.
Presumably you are referring to the 'often heated' back-and-forth that sometimes goes on in the forums when people refer to ANY PL/SQL type using a term with the word 'table' in it?
Curious that you then show an example of a nested table!
type emp_tab is table of employees%rowtype;
The 'right term' for that is 'nested table'. The following would be an 'associative array' or 'index-by table'
type emp_tab is table of employees%rowtype INDEX BY PLS_INTEGER;
Those used to be called 'PL/SQL tables' or 'index-by tables' but 'associative array' is the current term used.
Associative Arrays
An associative array (formerly called PL/SQL table or index-by table) is a set of key-value pairs. Each key is a unique index, used to locate the associated value with the syntax variable_name(index).
The data type of index can be either a string type or PLS_INTEGER.
Since the Oracle docs often use 'PL/SQL table' or 'index-by table' it isn't unusual for someone asking a question to use those terms also. Technically the types may not be 'tables' but it's clear what they mean when they use the term.
In PL/SQL the term 'nested table' is still used even though the PL/SQL collection is not really a table. SQL does have nested tables where the data is actually stored in a table. The PL/SQL 'nested table' type can be used as the source/destination of the SQL data from a nested table so that may be why Oracle uses that term for the PL/SQL type.
The doc that SKP referenced refers to this use:
Nested Tables
In the database, a nested table is a column type that stores an unspecified number of rows in no particular order. When you retrieve a nested table value from the database into a PL/SQL nested table variable, PL/SQL gives the rows consecutive indexes, starting at 1.

Couldn't fetch the data from the data source...[nQSError: 16023]

Hi all.
I think that the problem I want to discuss is well-known, but still I got no answer whatever I tried ...
I installed the BIEE on Linux (32 bit, OEL 5 - to be more precise), the complete installation was not a big deal. After that I installed the Administration tool on my laptop and created the repository. So... my tnsnames.ora on the laptop looks like this:
TESTDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.5)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = testdb)
And the tnsnames.ora on server, in its turn, looks like this:
TESTDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = testdb.localdomain)
The database worked normally and I created and transferred the repository to the server and started it up.
It started without any errors, but when I tried to fetch the data via the representation services I got the error:
Odbc driver returned an error (SQLExecDirectW).
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred.
[nQSError: 16023] The ODBC function has returned an error. The database may not be available, or the network may be down. (HY000)
I discovered, that the ODBC on my laptop was named not correctly (it should have been identical to tnsnames entry) - so I corrected it, saved and replaced the repository on the server and restarted it... - and still got the same error.
Apparently, something is wrong with the data source. So let me put here some more information...
My user.sh looks like this:
ORACLE_HOME=/u01/app/ora/product/11.2.0/dbhome_1
export ORACLE_HOME
TNS_ADMIN=$ORACLE_HOME/network/admin
export TNS_ADMIN

Can anybody point a finger where the error line is? According to the documentation it should work fine.Maybe the driver name is wrong? What driver I need then?
Cause I can't find it.
I'm really sorry to bother, guys :) Let me know if you get some ideas about it (metalink didn't help).

OK, several things wrong here. First the odbc.ini is not meant to be used for Oracle databases, that's not supported on Linux. On Linux you should OCI (Oracle native drivers) and nothing should be added on odbc.ini. Your user.sh seems to be pointing to your DB installation path. This is not correct. It should point to your Oracle client installation so you need to install the Oracle FULL client somewhere. Typically this is normally done with the same OS account as the one used for OBIEE whereas the DB normally runs with the oracle account. Once you got the client installed test it under the OBIEE account doing tnsping and sqlplus to your DB. Also the LD_LIBRARY_PATH should point to $ORACLE_HOME/lib32 not lib as the lib directory is the 64bits and OBIEE uses the 32bits libraries even in 64bits OSes. Finally change your RPD connection to use OCI. Make all those changes and you should be good.

Failed to fetch pluggable data source error

I'm getting this error when creating a report that is connecting to a DB2 table using jdbc. Report builder seems to connect to the database fine, however when I attempt to compile/run the report I get the following error -
'REP-4102: Failed to fetch pluggable data source.
java.lang.AbstractMethodError: COM/ibm/db2/jdbc/app/DB2ResultSet.getStatement'
I'm using the following in my jdbcpds.conf on my local machine.
<driver name = "ibm-db2"
subProtocol = "db2"
connectString = "subProtocol:databaseName"
class = "COM.ibm.db2.jdbc.app.DB2Driver"

Has anyone experienced this issue or has some insight as to what I need to do to resolve this?
TIA

Dear Oracle Reports Team,
Can you please help me out ???
Need your help in this regard urgently.
Best Regards,
Ramakrishnan L
Dear Friends,
I am encountering the following the error while running the reports.
REP-4102: Failed to fetch pluggable data source.
java.lang.NumberFormatException: 75,000000
I am using an Express Query in this case.
The same report runs perfectly when connected to the NT server that has the reports server,Http server and the rdf file.The db that the reports uses is on the SOLARIS server.
But when I use the reports server,http server and the rdf file avaiable to me on the SOLARIS server with the db also now on the same machine it does not run and gives the error.
What could be the problem ?
Just to add more clarity below is the URL which I use to display the report
NT URL(This works perfectly)
http://sa560:7778/reports/rwservlet?server=rep_sa560&report=c:\DWHReports\Man_Days_Spent.rdf&express_server="server=ora_ro_tcp:172.20.128.199/sl=-2/st=1/ct=0/st=1/"&destype=cache&desformat=htmlcss&OESHOST=172.20.128.199&SUSR_NAME='oraexp'&PASSWORD='test'
SOLARIS URL(This does not work and gives the error)
http://172.20.128.199:7778/reports/rwservlet?server=rep_gosisvr&report=Man_Days_Spent.rdf&express_server="server=ora_ro_tcp:172.20.128.199/sl=-2/st=1/ct=0/st=1/"&destype=cache&desformat=htmlcss&OESHOST=172.20.128.199&USR_NAME='oraexp'&PASSWORD='test'
