Probe shows the RMS incorect value in Multisim
Why Probe1 I (rms) value is not equal to Probe2 I (rms) + Probe3 I (rms)?
Because I'm a noob.
Probe2 I (rms) = I (rms) Probe1 / sqrt (2).

Trace files showing the bind variable value =""
10g on solaris
Hi all
We have a problem with an informatica workflow brings an update statement in Oracle in trems of performace.
I started using DBMS_SUPPORT tracing with lie the TRUE value. He captured the trace files accordingly against a controlled set of data. Trace TWOT files were produced.
Trace files first shows the SELECT statement are questions that identifies the records that will be updated.
The 2nd trace file shows the actual UPDATE statement published as a PL/SQL loop to do the update.
There are 20 records that users have rigged last updated and the update statement lists 20 cases where updates taking place. All updates occurred successfully after reviewing the results of the post. However my question is why the trace files are showing the values of bind as the value ""?... any ideas appreciated!
an excerpt of the file trace...

'dty = 1' indicates that the data type is VARCHAR or NVARCHAR. As the timestamp data types data types BLOB, and various other, bind variables defined as NVARCHAR will not have their values dumped in a 10046 trace file. I suspect that the: 1 binding variable is passed as an a NVARCHAR2.

PXI-6120 HAVE values only show the low limit values
Hello, I use a PXI-6120 with traditional DAQ driver module screws switch a signal of AI to a PFI channel that allows synchronization of area of OCCUPANCY the AI. In order to measure a single channel of AI with the same set-up, I stopped the criterion VI and tried to see the only measure max. Unfortunately, I opened a task DAQmx, I created for another application, which does not work probably because I have not reset the card after the stop of the VI. Since then, readings of IT are all flat on the lower limit values and the OD has remained at about 0.2 volts any value I write for her. In the meantime, I tried to reset and to recalibrate the device, which worked in DAQ and DAQmx (not the self-calibration in mx). But I have the impression, that the Council has kind of stuck in a State that I can't easily find and/or access. Does anyone have an idea, how can I do a factory reset, or what could be the problem? Greetings! Olli

acquire a signal and the rms value in a table every second
Hello everyone,
Sorry, but I am known in the world of LabView and I'm going crazy because I can't understand how to do a simple thing (or what it tends to be in my mind).
As said by the object,
my wish is to acquire a digital (a through the DAQmx) continuous (it's ok for this part), get the RMS (or average) of such acquired signal (thanks to the Amplitude and levels of measurement, for example) and put the value in a table (1 d); and, every second.In one sentence: acquire a signal, the average value, put in a table, and then restart each second. In the end, for example, the program for 1 minutes gives me 60 value in the table.
Is someone can help me?
Thank you in advance.
Viviogs.
First of all, I'm not sure that you can be sure exactly a second measurement using this technique. If the precise timing is important, I think that you need a timed loop.
That said, if the only problem you have is how to write the table indexed in a spreadsheet, you just need to use "Write in the worksheet file." See here.

Hello
I have the choice of Message box, in which I'll show the inventory list organizations are assigned to responsibility. I just the following query in the query of LOV...
Select hou.NAME separate organization_name, mp.organization_id
of mtl_parameters mp
, hr_organization_units hou
oa org_access
where mp.organization_id = hou .organization_id
and hou.organization_id = oa.organization_id
and oa.responsibility_id = fnd_profile.value ('RESP_ID')
organization_id asc order
But first let's say after the OA Core bounce if I open a responsibility which is to have access to 5 associations of the inventory, and then in the message of choice is showing correctly... But when I go to another responsibility that is to have access to a single inventory, always the choice of Message body shows the previous inventory 5 Orgs who is to have access to the prior responsibility.
Pointers on this?
Thank you

Why can't I just show the value of the reference variable on name full column
Hello everyone,
I want to display the value of the reference variable as column name for one of my analysis on OBIEE. However, when I write, it does not show the value, it shows just as text;
VALUEOF ("rv_yesterday")
How can I show the value of it?
Can you help me please.
Kind regards
Dilek
Raja,
What is a date or a related data type in any variable of RPD - session or repository - will become a datetime. That's a given and you can play as much as you want with to_date, trunc, DATE (the way of the RPD), but will it be a datetime value. Period.
Only when she is cast to a string rather than one of the 'date' data types can get rid of the component "hour".
Edit: Sorry, I forgot to add: < dilek,="" that="" response="" is="" your="" answer="" as="" well,="" sorry.="" no="" "date="" without="" time="" component="" in="" proper="" data="" types."=""> >

DESC, showing the different type of data value via dblink
Hi friends,
We have two databases and for two of them, the configuration is as below
Version of the operating system: Solaris 5.10
DB version: 10.1.0.4
For security reasons, I'm going by names of junk. Assume the names of database DB1 and DB2.
We have a table T1 S1 schema of database DB1. to extract data from this table in DB2 in schema S2, we created a database DB1 and DB2 (lets say the name of dblink is XYZ)
In DB1, in table T1, we have a column by name SYS_CREATED and its data type is varchar2(40 char).
After you create the database link, below we have the table as desc
DESC S1. T1@XYZ
When we describe this statement, instead of showing the value of data type of column SYS_CREATED as varchar2(40 char), it's showing as varchar2(160 Char).
Then, we created a table in DB2 under schema S2 as below
SQL > create table S2. T2 in select * from S1. T1@XYZ;
and now, when we describe the table T2, its original display value is varchar2 (40 Char).
Then just when we described, it shows a higher value for the data type and when we create the table, his watch even than the original. In addition, what is happening to only varchar2 datatype. other data types such as number or tank remain same even when we describe.
one thing is, when he demonstrated a different value using describe, sound exactly multiplying by 4 times. for example, if we have varchar2 (1000 char), the varchar2 (4000 tank) showing
I would like to know if anyone in this strange situation earlier, if so, what is the reason?
Thank you very much in advance

Add filter slot table form to show the lines with null values
Hello
I have a tabular presentation where we need to add a filter with two values (selection list) so that if one of the columns in a table (column1) is zero, then I need to display all records where column1 is null.
I was wondering how do I put this in the Source of tabular forms where condition. This filter has only two values,
All the
NULL for the error
So when the user selects all, then all the records in the table are shown
If the user selects 'Value Null in error', while the records where Column1 is null will be shown
For example
If the user selects, thencolumn1 column2 A B 1 C 3 D
all four files will show up. Else, only the first and the second will be returned.
Thank youHi, Ryan.
Try a static LOV like this
STATIC2:;,--- All ---;--- All ---
and a Where clause, like this
where column1 is null or :p1_filter like '%%'

In the column of table when the values are grater that maximum linear axis it does not show the bar
Hi guys,.
In the column of table when the values are grater than there maximum linear axis it does not show the Bar.But I want to display the bar up to the maximum limit of the axis is linear without changing the limit max.
Consider following the example:
The values are 80 90 200 300
and here is the result:
Left: when I don't put maximum property of linear axis.
Right: when I put in maximum property of linear axis to 200.
Law 4th bar is not visible because the value of this bar is 300 which is excedding maxium. But I want the 4th bar to appear identical to 3 bar.
How can I do this?
Thanks in advance.
Then you should change the value of Y to the maximum value.
Another option, you should consider is changing the Render item column to reflect that the value is greater than the specified maximum value.

ADF LOV->; UI: main table showing the fields ID and not the search values
Hello
I am very new to the development of the ADF and will have a simple question that I can't solve.
Using Oracle JDeveloper 11.1.2.0.0 I create my views and objects of entity without incident. I have an entity object that has several "search values" (these are all optional references to foreign keys to tables 'children'). Objects and relations are perfectly mapped the ADF.
In the views of child object I created the list UI tips
-Type: Combo box with list values
-the "selected" column is the "description" of the research
in the editable display object, I traced the fields 'id' to use the predefined LOVs.
This works as expected in the user interface, I created with an ADF table can be updated.
However (here's the noob question), the "id" is displayed in the search on the table column. When I click the menu drop-down I can see the description, etc, but for a professional user when they look at the table, they see an unfriendly identification number.
How can I get the part of the LOV display to show the description, while remaining linked to the ID of the parent entity.
for example, it shows
while I want to display:Country LOV1 LOV2 LOV3 United States 15 18 2
If this has been answered several times or walk through there, sorry for the redundant question, I simply can't find a solution!Country LOV1 LOV2 LOV3 United States Washington Seattle Rain
Hello
There are several ways to do this, you simply need an additional outputText next to the lov component field to display the value of the description.
If you search the forum or adf blocks, you'll find several implementations.
And here's one: http://andrejusb.blogspot.com/2010/06/lov-description-text-with-groovy.html

Produce a graph showing the lowest of the 4 hourly values as a point
Good, new to this forum.
I am producing a graph in the APEX that shows the lowest value of every 4 hours to produce a point in my chart to a monthly chart.
I created a calendar for flashback data every hour from a database.
Then this bit of SQL for a diagram of the weekly display data of each hour:
Select the null link,
TO_CHAR (current_date, 'MON-DD-YYYY HH24') as a label,
(OLDEST_FLASHBACK_TIME * 24) AS #.
of flashback_history
where DATABASE_NAME = "#"
I want to get the lowest value of all 4 hours and display in the chart for a month.
Sorry if this makes no sense!
Thanks in advancewith tab as (select todays_date dt, OLDEST_FLASHBACK_TIME * 24 value from flashback_history where DATABASE_NAME ='####' ), -- end of mimicking a table "tab" containing some data results as (select dt, value, 4 * trunc((row_number() over (order by dt) -1) / 4) grp from tab) select min(dt) keep (dense_rank first order by value) dt, min(value) from results group by grp order by 1;

Need to show the same values in all jspx pages
Hello.
I use jdeveloper 11.1.1.5
I had created a jspx pages such as dept.jspx and emp.jspx
I've been using this in my jspx page
The bindings.return.inputValue will return the value of the code below<af:outputText value="#{bindings.return.inputValue}" binding="#{pageFlowScope.backing_dept.ot1}" id="ot1"/>
My scenario is that I need to display the same value in emp.jspxpublic String checkLoginCredentials1(String p_user,String p_pwd) { System.out.println(p_user + " " + p_pwd); ApplUsersVOImpl vo = (ApplUsersVOImpl)this.getApplUsers1(); /*set the bind variable value*/ vo.setNamedWhereClauseParam("p_user",p_user.toUpperCase()); vo.setNamedWhereClauseParam("p_pwd",p_pwd.toUpperCase()); vo.executeQuery(); int rowCount=vo.getEstimatedRangePageCount(); System.out.println("rowCount="+rowCount); if(rowCount==0) { throw new JboException("Password doesn't match"); } return "Welcome"+ " " + p_user.toUpperCase(); }
I had created a task flow frm dept.jspx to emp.jspx and emp.jspx to dept.jspx
I tried the same XML file in my emp.jspx
But while I m browsing frm emp.jspx to dept.jspx there are doesnot.,.<af:outputText value="#{bindings.return.inputValue}" binding="#{pageFlowScope.backing_emp.ot1}" id="ot1"/>
This means that for the faces-config. XML (the standard JSF configuration file), there is no scope spanning application except for the scope of the session. This does not mean that you should not use extended session if you use faces - config.Xml.
However, you have been advised to use the workflow and no faces - config.Xml.
