Unable to capture data from Serial port using LVRT2010 in single core pentium 4 machine

I am using application written in Labview using windows Labview
Runtime environment 2010. Application creates a tunnel to intercept data from
Serial port.
My problem is, Currently, I am using single core Pentium
processor. When I am trying to intercept the data between COM1 and COM7 (COM 7
is a virtual port) it is not able to capture data.
When I am running Labview RT environment using dual core
processor machine it is running normally. I wonder whether it could be the compatibility issues with
single core Pentium processor.

Hi Magnetica
Are both of the machines running the same runtime engine,
drivers ect?
Have you had RT applications running on this
machine before?
Is the development computer a 64bit machine?
The processor is a supported model (See link below).

Single query to get data from different databases

i need to capture certain fields from certain tables in database 1 and certain fields from certain tables in database 2 into one file using a single SQL statement.
i tried searching on the net
i found that dblinks can help
but iam not sure if ill be able to create dblinks in my situation which is:
i need to get data from oracle to be copied to mysql
this is not a replication acitivity, but i need certain fields from one database and certain from the other
so what iwas thinking is, if i use an sql query to get all the fields (i need around 40) from the different oracle databases and create a singlefile with one insert per select, i can then read that file into mysql
instead of creating multiple sql queries for each table and creating separate files and eventually separate tables in mysql.
can anyone help me here?
or maybe suggest another approach.
thanks

Hi,
I think dblink is the only option available to get data from different databases. It will work for your case too.
CREATE DATABASE LINK db_link CONNECT TO user_name IDENTIFIED BY password USING 'instance_name'you must have the system privilege 'create database link' to create db links. This way you can get the required data and put it in a table in oracle. But i dont know how to put this data from oracle table to Mysql.

InfoCube Modelling-Adding data from different ODS's on to the Infocube

Hi Experts,
I am new to SAP BI. I have a basic doubt on Modelling the InfoCube.
In our requirement, I have to populate data from 9 custom SAP Tables on to 9 ODS's. And, then take these data on to Infocubes.
And, they want to reduce the number of cubes as much as possible. So, I have to combine the data from different ODS's and build 2-3 Infocubes.
For Example.
I am going to combine 5 ODS's data on to 1 CUBE based on Delivery number...
there are 5 ODS with common key Delivery number. And, suppose I have added some set of fields from ODS1.
And, now when I add other set of fields from the second ODS, WHAT WILL HAPPEN TO THE 'Delivery Number' field ??
I will make it clear.
I have a record in CUBE already containing Fields- : Delivery no, field_a, field_b, field_c, field_d. Where the 'Delivery no =112333'. This record comes from ODS1.
Now, I want to add data data from ODS2, containg fields -: Delivery no, field_e, field_f, field_g, field_h.
And, what happens to the already existing record in CUBE with 'Delivery no = 11233'. ?
Will the value in this info-object get overwritten ?
OR.. will it combine the data from both the ODS's and show it as ONE record ???
Please advice ... How will I solve this scenario ?
Thanking You in Advance
Shyne Sasimohanan

Answer for your question and the suggestion.
the data will look like as given below
Delivery no, field_a, field_b, field_c, field_d, field_e, field_f, field_g, field_h
11233           1           1           1          1            0           0            0            0
11233          0           0          0             0           1           1           1          1
but the best way, according the design standards is creating another DSO on the top of all the DSO's and combine all the data in that DSO and send the data to Infocube. then the data will be shown as below.
Delivery no, field_a, field_b, field_c, field_d, field_e, field_f, field_g, field_h
11233           1           1           1          1            1           1           1          1

How to combine data from different input forms outside a nested iView

Hi,
i try to combine data from different input forms in a single one.
Because of space reasons in Flex compiling i already use nested iViews. Within these nested iViews its possible to use the 'combine' function to do this.
But in the main iView I cant compose these function with other elements. I need to do this because of using these model in Guided Procedures with output parameters. These parameters I only get with a 'endPoint'. Unfortunatly its not possible to combine data from different input forms into the 'endPoint'.
Is there any solution?
Thanx
Mathias

Hi Scott,
i tried this already and i also tried to map all parameters in the endpoint by drawing lines from the other forms and assign the 'empty parameters' by a formula.
And when i create a collable object in GP and assign the VC iView, only the parameters of the parent-form (the form who trigger the event) are shown as output-parameters.
Maybe any other ideas? I cant believe that such a simple thing is not possible?!?!
In my opinion, thats a bug, that I'am not able to use the combine-operator in the main VC-iView. Whats your mind?
greets
mathias

Data from different databases in the same report.

Hi Everyone,
I am trying to build a reconciliation report in which I need to show the data from the source and target, side by side.
Source and target are both different databases, although being oracle only
Whenever a new data model is created, it gets attached to a data source and in the report we need to choose a specific data model.
Can we have data from different databases in the same report ?

Yes, it is possible.
One way Is to use dataTemplates. There you can make queries from any number of different databases (The max I have done is 5).
It looks something like that:
<dataTemplate name="NameOfTemplate">
<dataQuery>
     <sqlStatement name="Q1" dataSourceRef="Connection1">
          <![CDATA[     select * from table1]]>
     </sqlStatement>
     <sqlStatement name="Q2" dataSourceRef="Connection2">
          <![CDATA[     select * from table2]]>
     </sqlStatement>
</dataQuery>
<dataStructure>
     <group name="RESULT1" source="Q1">
          <element name="P_FIRST_NAME" value="P_FIRST_NAME"/>
     </group>
     <group name="RESULT2" source="Q2">
          <element name="P_DATE" value="P_DATE"/>
     </group>
</dataStructure>
</dataTemplate>dataStructure is very important when you get data from different places, if you don't define those elements, then only the result from Q1 is shown.
The second possible way is to make as two different data models, each containing their own query and then set Main Data Set as concatenated SQL Data Source.
Best of luck,
Evelyn

How to display multiple data from different table in one table? please help

Hi
I got sun java studio creator 2(the separate installation not the one in the net beans)....
My question is about displaying data that have been taken from the database.... I know how to display data in a table(just click on the table "bind data" )... but my question is that:
when i want to use a sql statement that taken the data from different table...
how can i display that data in the table(that will be shown in the web) ??? when i click bind data on the table i can only select one table i can't select more than one....
Note:
1) i'm using the rowset for displaying the data in the table, since the sql statement is depending on a condition(i.e. select a from b where c= ? )...
2) i mean by different table is that( i.e. select a from table1,table2 )..
thanks in advance...

I want display the details of emp table.. for that I am using this SQL statement.
select * from emp where mgr=nvl(:mgr,mgr);
when I give the input as 7698 it is displaying the corresponding records... and also when I won't give any input then it is displaying all the records except the mgr with null values.
1)I want to display all the records when I won't give any input including nulls
2)I want to display all the records who's mgr is null
Is there any way to incorporate to include all these in a single query..It's a little unclear what you're asking.
The following query always includes rows where mgr is NULL, and when the bind variable :mgr is NULL, it displays all rows:
SELECT *
FROM     emp
WHERE     LNNVL (mgr != :mgr)
;That is, when :mgr = 7698, it displays 6 rows, and when :mgr is NULL it displays 14 rows (assuming you're using the Oracle-supplied scott.emp table).
The following query includes rows where mgr is NULL only when the bind variable :mgr is NULL, in which case it displays all rows:
SELECT     *
FROM     emp
WHERE     :mgr     = mgr
OR      :mgr      IS NULL
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL it displays 14 rows.
The following query includes rows where mgr is NULL only when the bind variab;e :mgr is NULL, in which case it displays only the rows where mgr is NULL. That is, it treats NULL as a value:
SELECT     *
FROM     emp
WHERE     DECODE ( mgr
            , :mgr, 'OK'
            )     = 'OK'
;When :mgr = 7698, this displays 5 rows, and when :mgr is NULL, it displays 1 row.

How to insert data from different internal table into a data base table

hi all,
I want to insert a particular field in an internal table to a field in a data base table.Note that the fields in the internal table and database table are not of the same name since i need to insert data from different internal tables.can some one tell me how to do this?
in short i want to do something like the foll:
INSERT INTO ZMIS_CODES-CODE VALUE '1'.
*INSERT INTO ZMIS_CODES-COL1 VALUE DATA_MTD-AUFNR .(zmis_codes is the db table and data_mtd is the int.table)

REPORT ZINSERT.
tables kna1.
data: itab LIKE KNA1.
data lv_kUNAG LIKE KNA1-KUNNR.
lv_kuNAG = '0000010223'.
ITAB-kuNNR = lv_kuNAG.
ITAB-name1 = 'XYZ'.
INSERT INTO KNA1 VALUES ITAB.
IF SY-SUBRC = 0.
WRITE:/ 'SUCCESS'.
ELSE.
WRITE:/ 'FAILED'.
ENDIF.
Here lv_kunag is ref to kna1 kunnr passed in different name
In internal table .
Try and let me know if this logic dint work.

Problem in reading data from serial port continuously- application hangs after sometimes

I need to read data from two COM port and order of data appearance from COM port is not fixed.
I have used small timeout and reading data in while loop continously . If my application is steady for sometime it gets hangs and afterwards it doesnt receive any data again.
Then I need to restart my application again to make it work.
I am attaching VI. Let me know any issue.
Kudos are always welcome if you got solution to some extent.
I need my difficulties because they are necessary to enjoy my success.

What do you mean, "not fixed?" If there is no termination character, no start/stop character(s) or even a consistent data length, then how can you really be sure when the data starts and stops?
I probably misunderstood you though. Assuming the last case is not ture - there is a certain length to the data - then you should use the bytes at port, like in the otherwise disastrous serial port read example. In this case, it's NOT disastrous. You have to make sure that you read all the data that came through. Right now you have no idea how much data you just read. Also, if this is streaming data, you might want to break it out into a producer/consumer design pattern.
Not fixed means order is not fixed, data from any com port can come anytime. lenght is fixed, one com port have 14 byte and other 8 byte fixed..
Reading data is not an issue for me as it works nice but I have a query that why my application hangs after sometime and stops reading data from COM PORT.
Kudos are always welcome if you got solution to some extent.

Select data from different database

hi,
may I know how to select data from different database?
for example,
I've 2 databases, OracleDB and OracleAR
Connect with OracleAR in SQL*Plus
select * from OracleDB.TableName
does Oracle support this kind of query?
how can I retrieve data from other database while im connecting with
other database?

Hi,
Yes, it's possible. No, your syntax won't work.
First of all you have to define a DATABASE LINK inside the DB where you are already connected (in this case OracleAR). Read docs how to do that.
Second thing is the query. It will look like
SELECT * from TableName@<NameOfDatabaseLink>Greetings,
Guido

Retriving of data from different tables

retriving of data from different tables depening of the primary key this key field is there in all tables if it is there in one v table it should continue to other tables otherwise it should get exit from that it should display information message or otherwise success message if it is there in all tables .

Im writing the concept, just check it.
SELECT * from kna1 into lt_kna1.
if sy-subrc eq 0.
selest * from lfa1 into lt_lfa1
