Channel used in Rman

Hello

What is the channel in the RMAN backup. What is the use of the channel in the RMAN?

Thanks in advance
ASIT

A RMAN channel is a communication pipeline between an RMAN executable and a target or auxiliary database. An RMAN channel consists of a server on the target or auxiliary database session and a stream of data to the unit of backup or vice versa. RMAN console sends commands to the database using this channel, and the session running on the database server executes the command on behalf of the RMAN Recovery Manager.

The strings that you entered in your file name conversion settings does not match where actually your data files. If the string does not match the names of files, there is no names of files to convert. Because you're on windows, how about something like this?
```
set db_file_name_convert='\ORCL\','\ORCLSTD\'
set log_file_name_convert='\ORCL\','\ORCLSTD\'
```
Hope that helps...

Error in the capture of several channels using pre-trigger

I have problems of acquiring data with pre-trigger samples during the capture of several channels, using hardware NOR-PXI-6071E and Analog Input VIs in Labview (inheritance OR-DAQ).

My goal is to trigger a signal, while capturing another. Unfortunately, I can't use the PFI0 for external triggering, as our cables/material have already been built, so I have to use an analog input as the trigger channel. I understand that to do this I must capture the two strings and the string I want to trigger outside must be the first string in the list.

If I trigger and capture on the same channel (I tried 1-4) then it works very well, regardless of the number of samples before relaxation together. If I capture more than one channel (the channel of the relaxation to a first), with no pre-trigger samples, then trigger and capture both work very well. However, if I do the same thing with pre-trigger > 0 sample I get the following error:

Error-10621 to AI control. Possible reasons:
NOR-DAQ LV: The specified trigger signal cannot be assigned to the resource for the trigger.

I don't have to such limitation explained in the user manual, and the forum search, I found a few other people who have had the same problem but they had no solutions. Any ideas?

Hi Jackson,

Unfortunately, this is a hardware limitation when you reference analog trigger via one of the lines to HAVE.

Please see this knowledge base. Particularly the second paragraph says

The error-10621 appears immediately when the VI running if you try to assign scans of relaxation before while scanning multiple channels and using one of the entries as your trigger channel.

Details are explained in the third paragraph:

Because all the entries are multiplexed before being sent for analog triggering circuit, it is possible that the trigger on the trigger channel conditions might miss while the device is multiplexing by another channel. In this case, the trigger will not be detected.

It is explained in the E-Series user manual page 10-3. Specifically the second paragraph of the section entitled "Analog Input Channel".

Numberic channel using Dict.Add text conversion

I have several channels that have a text value for them and I used a Dict.add function to change the values of a number so it can be traced linearly. However, I had to create a separate for each channel in the set data function. I want to generalize it more so it will come out and watch an all channels and compare the values of the dictionary already created. I have attached a sample form of how I currently do not change and I played with a new form called TxtToNum.vbs which is more widespread. I have 6 dictionary that I use in total as well so who plays in the task. I do a lot of work of script and could really use it little assistance.

Interference between channels using a block of cFP-TC-120, CB-3 connection

Using a CB-3 with a cFP-TC-120 module connection block for read sensors millivolt. The sensors are pressure with an excitation of 10V sensor. Millivolt signal varies 8mv to-70mv. All have 8 differential channels wired in two of these modules sitting in slots 3 and 4, a slot 4 back on the plain. There is also the 24V in the electrical box used by two modules to relay PSC - 421 driving valves that open, leads at room temperature or in separate the empty rooms they are in slots 1 and 2. Do to the cFP-TC-120 the same and each is affected in the same way, more interference is not only between the same module 120 channels, but also between the modules! If a sensor is vacuum where the millivolt is around 7 mV reading is stable through the following conditional changes. "If a sensor is emptied at room temperature, say channel 6 and channel one is already at room temperature its reading can change by 0.25mv be affected by the evacuation of other channels. This worsens proportional number of channels is ejected by up to 0.5 mV for all other channels that are evacuated. This module is differential and each channel and the module are isolated we don't understand where or how this interference takes place. Help!

Ben,

We have done some trouble shooting and isolated in millivolts sensor signal of the NOR. We found that voltage was real and electronics is not the field point. The system runs on 24V except for sensors that have an excitation of 12v. We found that the Commons between these continuous tensions were just that, each have been shared. We have separated the Commons and vola! Perfection.

Need help to set up an acquisition of two channels using NI5154

Hello experts NOR:

I'm setting up a scanner high speed data acquisition NI5154. I have two data channels need to be measured. In fact only the waveforms in the channel 1 must be recorded and channel 0 is used for counting digital pulses.

My goal is like this: once started, the digitizer should count the digital pulses in channel 0 for some time until a start trigger happened in the channel PFI_0. After receipt of the beginning in the channel PFI_0 relaxation the digitizer should switch to channel 1 and start captured signals and save them to the disc. After a well-defined time, stop digitier the acquisition in channel 1 and then switch to channel 0 and repeat as cycles.

my questions are: what the best way to count the Digital pulse channel 0 ? The only way I know is the source of reference on channel 0 command and then get the number of "Done Records" from the property node. After the acquisition of the digitizer will be waiting for the trigger to start in the channel PFI_0, no pulse in the channel 0 will be counted. If I let the impulses in channel 0 not counted in the first cycle, at the end of each cycle how can I switch from channel 1 channel 0 and saitch return after receiving the trigger from the beginning? It seems that I have to configure the trigger repeatly system.

How to read voltage on several channels using the 6255\SCB-68

Hi all

I have been able to get the following code to compile, run and display the data as expected. When you read the tension (CSR) on Dev0/ai65

... Instruments\NI-national DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage\Cont Acq - Int Clk\ContAcq - IntClk.c

* I think I'm using CSR, but I have no idea since I don't see an argument to specify

I'm reading two different data points:

1 discovered (CSR) tension on Dev0/ai65

2 show the (differential) voltage difference between Dev0/ai17 and Dev0/ai25

Can someone point me to an example (or a web link) where two different data points are read.

* edit - I am filling this task using C++

Thank you

How to replace the units of a channel using scripts % 3F

Hello

I have a few questions about the manipulation of the channel property 'unit' by scripts.

Case 1: If the unit in the chain is not specified in the properties, what command should be used to add the inside unit?

Case 2: When I create using the string ' Call.Root.ChannelGroups (1). Channels.Add ("name", DataTypeFloat64, 1)', empty space of unity being, what other command can be used which was available to the units to the breast?

Case 3: Consider that I have channel (channel A) with the already defined unit (x), how can I replace the unit with another (y)? (Units of x and there belong to different physical quantities, so the ChnUnitConvert)

Pls let me know if you nee details on the same.

Kind regards

Fazil Shah.

Hi Fazil,

The key word for SCRIPT DIAdem units is "unit_string". If you open the SCRIPT and open the channel property list you can select the property unit and drag & drop it in the SCRIPT Editor. This creates the code of script for the property.

Case 1
You have the options of towing: a quallified assignment complete or a channel object variable (if you have more settings for the channel of the second alternative is better)

Data.Root.ChannelGroups (1). Channels ("mychannel"). Properties ("unit_string"). Value = "MyUnit.

or

Dim oChn
Set oChn = Data.Root.ChannelGroups (x). Channels ("mychannel")
oChn.Properties ("unit_string"). Value = "MyUnit.

case 2
You must add the unit after the creation of the channel

Set oChn = Data.Root.ChannelGroups (x). Channels.Add ("MyChannel", DataTypeChnFloat64)
oChn.Properties ("unit_string"). Value = "MyUnit.

case 3
It's the same as case 1 or if you do not want to use an already existing channel device, it can look like this

oChnA.Properties ("unit_string"). Value = oChnB.Properties ("unit_string"). Value

I hope that answers your questions

Greetings

Imaging multi channels using the acquisition card OR

We have a 1408 IMAQ being controlled by LabVIEW 8.0.

We want to install multi-channel of imagery. All the channels work individually. However, when I was trying to show two channels simultaneously, single channel works and I got the following error message:

Error 1074397150 has occurred to IMAQ enter Setup.vi

Possible reasons:

NOR-IMAQ: A timeout error occurred while you wait for the specified event. If you expect a picture, make sure all the video data is acquired during the period. If you wait for a signal, check that the assertion of signal occurs within the period.

Sometimes I get a different error message asking me to assign different buffers to both channels. I understand that IMAQ 1408 has only analog digital (ADC) converter to digitize the incoming video. It may acquire up to four different cameras, but only of a camera at a time.

I don't mind do frame rate in half. I think to show only one channel at a time and do the two channels alternantly. But I need to know how config routes to get there.

I've attached an example that should work. I could not test it because I don't have the equipment, so it might need some settings. I would test it with one channel by setting the channel # 1. Once it works, define channels # 2. I set the display to use snapshot mode so the same image can be used for all screens.

The only reason that I can think of that would make multi-channel acquisition fail when single channel works is the lack of synchronization between signals. The start of frame signal must be the same for all channels.

Port 20Gbit-channels using ports sfp +.

Hello

I hope to implement a cost affective solution who can use ports for uplinks on the X 2960 & switch series XR and where appropriate to the top/downlink modules for X 3750 series switch

If someone knows if it is possible to group ports sfp + 10 GB in a channel port 20gbit?

Whoever did this or they could point me in the right direction for documentation?

Thank you

Yes, it can group several ports 10Gig on all these devices as long as you have the appropriate modules. 2960 X supports up to 24 Etherchannels and the XR up to 48.

If you are uplnking the 2960 3750-X series, you need a 10Gig for X-3750 series module.

Windows Media Center will not scan digital channels using a dual tuner (analog/digital)

I have an AverMedia Volar Max tuner which is analog and digital double Windows 7 Professional
Media Library 'sees' the tuner as an analog tuner and properly identifies all the analog channels, that I see on TV.
However, none of the digital channels are detected. I have not found a way to "force" a search using QAM256 or any other research of digital formats. Using the tuner, cable and connections the same BUT with a linux sotware (mythtv) all digital channels have been identified.
Is the problem because its analog and digital modes? How can I force Media Center to see the digital capacity of the tuner?

Might have been a better place to look for information on the AverMedia Max Volar tuner AverMedia USA site.

If you had looked here to find the latest drivers or to read support information, you would have found:

Currently, Microsoft Windows Media Center does not signal QAM. You will need to use our AVer Media Center in order to receive the QAM signal. Please download the application on our website programs:
