• Why convert? What is the advantage? Why convert it before you send the data over the network?

  Hello everyone.

  I have a question quite simple and intuitive. Yet Google does not seam to get the answer.

  Basically, I'm curious why should we catalogued something? It seems to me that it's just a little like a "band-aid" for editing data in conversion to a new data type, when it is not properly declared with an appropriate data type. What would be the advantage of this?

  Furthermore, I see a lot of data type casting to U8 programs before sending it over the network. Various reviews say it's for speed, but I can't understand how it improves speed. The same amount of data is still sent, just in a different type of data. This is overcoming a limitation of the network. The network somehow send smaller data types faster?

  I've been curious about this for a while and have yet to find an answer. Any help is appreciated.

  Thank you

  It really depends on the specific situations.

  For example, some functions explicitly require certain types of data as inputs if they are not polymorphic.

  This means that if you do not convert the data yourself and you will see a red dot forced LabVIEW will do it for you.

  As to why the data was not the correct data type in the first place, it is sometimes inevitable.

  A few examples

  -What happens if you just read a text file as a long string.

  If there is digital data in this file, you need to analyze, and then convert it to a usable type (int, sgl, dbl, etc.)

  -you are given a 3rd part VI, dll, etc. that returns a numeric value as a double, but you need the value to I8.

  You cannot change the output of the function given to you, so what you can do to remedy this situation is cataloged data.

  Somehow, this is my first response, but in a more general sense.

  Many functions down to the level of the OS run in binary.

  If your data are not already in binary, the sending computer must convert it to binary, and then send it, have the receiving computer convert in return.

  Two conversions on each side of the transmission add unnecessary delays.

• How does a datapump decide exactly the RCS over a network link?

  I have a question. I use flashback_scn on one of my scripts and I was wondering if I have not specufy the flashback_scn?
  
  How does the data pump without flashback_scn on network_link? How does he decide to what YVERT must export?
  
  I am importing about 40 gigabytes of data which easily takes 2-3 hours on the network link.
  He decides on the SNA at the start of the work?
  
  What new data coming in 2-3 hours after I started the import job?
  
  Looked around in the documentation, but could not find any useful information on this.

  If you do not specify flashback_scn or flashback_time then only data that matches data in partitioned tables. It could also include nested tables, but it does include all the tables.

  Let's say your network work includes these objects table_data and they are exported in this order and say that you add enough data to add 1000 to the RCS every 1/2 hour:

  time object Yvert
  11:30 table0 - unpartitioned 1000
  12:00 table1:partition1 2000
  12:30 table2 - non-partitioned 3000
  01:00 table1:partition2 2000
  01:30 table3 - non-partitioned 5000
  02:00 table1.partition3 2000

  If you do not specify a parameter of flashback, then only compatible data for table1. All 3 partitions will be exported with the SNA even. The CPN is the RCS at the first partition is exported. In the case precedent, if the first to export data of SNA 1000 the first partition of table 1 is exported from SNA 2000, then all partitions table 1 will be exported from SNA 2000. No other data is forced to be exported to the SNA 2000.

  In exp/imp, you could say in line = y, but is not available in expdp/impdp. If you want all the data, you must specify a parameter of blowback. One of the easiest ways is to use:

  flashback_time = sysdate

  There was a problem with it in version 10 and I know it's fixed, but I do not know more what version it is attached to.

• HP ENVY 4520: HP Envy 4520 - refusing to Scan over the network

  Hello

  We currently have a HP Envy 4520, which print, however don't scan or copy over the network.

  I have downloaded and run the HP doctor tool, but it crashes to Windows Image Acquisition (WIA). This article has been read a few topics here, I restarted the following three services:

  1. Remote procedure call (RPC)
  2. Shell Hardwarew
  3. Windows Image Acquisition (WIA)

  Once I finished at the outset what precedes, the scanner worked as expected. However after a reboot - the problem is more severe. The doctor program crashes at the same section and restart services fail to achieve something.

  All software and drivers are up-to-date by using what has been provided on the HP website.

  The error messages vary as well, for example Adobe, I see "fatal error. Commissioning stopped. "

  Hi @DocCottle

  Thanks for your response!

  I managed to solve the problem. After you reset the windows service, you must then make sure that the printer restarts too! I didn't do that. Once done all is well!

• LaserJet P2055DN - do not print over the network

  Configure the printer last night as a network printer (which replaces a former 2300dn LJ). It would not print a test page. To verify that the printer was good, I have loaded the drivers on my laptop and connected via usb.  Was able to print a page of test via USB.  Disconnected usb and reconnected power cable. Released and reset the ip address.  Verified the ip address in scathing of the host.   When I ping the printer I usually lose half of the packages.  There are two other HP printers on the network, a P2015dn and a color 2605dn LJ. Ping their IP back to 100% with a ttl = 255. Ping the p2055 produced 4 packets sent, 2 packets received, 2 lost packets, ttl = 64 2 returns.  I changed the printer cables and exchanged the network switch ports (verified the network switch ports by printing to the LJ 2605) with the same result. I can't get the internal web server to mount, or it partially displays or combinations of these.  If this was the old style removable print server as in my lj2300, I could swap out, but it's not like I can do with this model.  When I send a test page to the printer, it displays "printing", the green light on top flashes, the activity on the network card light flashes, but nothing happens. Finally, I get a «this document failed to print "notification on the host, but the printer still says 'printing' and the lights are still flashing.»  Anyone have any ideas?  I think I'm looking at a bad network/print the server maps in the P2055.

  I also had problems printing over the network to the hp p2055dn. There was no problem via USB printing. All the network settings were ok. Can ping, etc...

  Number of days of bickering, finally found that the Config.Security Network should be reset on the physical control of the printer Panel.

  Press Ok on the Control Panel printer--> press down arrow, you get to Setup Menu Network Config--> press Ok--> a number of arrows down you get to Config network. Security--> press Ok--> you have two options - keep or reset--> choose Reset... Network printing should work fine.

• HP 2520HC: install the software of the printer over the network

  Hello

  I use the HP 2520HC series at the office. I use a network connection.

  Printing works fine, however I want to be able to scan as well. I downloaded the printing software, but the only option I choose, connect via USB? The printer is connected to another PC, so this isn't an option.

  Please help me.

  Hello

  such a USB printer allow only all features on a directly connected USB computer.

  Sharing a printer over the network allows sharing of a printer, Windows don't offer any scanner, the sharing feature.

  You can print from another PC to a shared printer, you will not be able to analyze such, to analyze the use of the computer connected directly to your printer via a USB port.

  Kind regards

• try to print from my Win7 x 64 laptop over the network (homegroup or workgroup) to an enslaved Dell Photo AIO Printer 926

  I'm trying to print from my Win7 x 64 laptop over the network (homegroup or workgroup) to an enslaved Dell Photo AIO Printer 926.  When I look for the computer on the laptop, I find, it seems to be fine, but when I print a job, the print job is in the queue on the laptop and does not send the job to the desktop printer.  I had it once before but a relocation removed.  I'm not sure why I see the desktop of my laptop printer but cannot get it working again.

  Any advice?  Thank you

  You need the Windows7 x 64 drivers for the printer (and perhaps software and fimware) installed on your laptop to be able to print using the printer on another computer if he uses another operating system...  Maybe when you reinstalled you forgot to install these things.  Try this and see if you can then print.

  If this does not help, please post in the Forums Windows7; http://social.answers.Microsoft.com/forums/en-us/category/Windows7 where Windows7 experts will be happy to help you.

  I hope this helps.

• printer cannot be contacted over the network

  I have a HP deskjet 656 printer that I added as a network printer. I installed it on my computer laptop windows 7, which went well. However it does not print. The touble shooter printer tells me to 'the printer cannot be contacted over the network. It works from another laptop I have but not my laptop Windows 7.

  I had a similar problem with my new Windows 7 laptop. After a power failure, the laptop would not recognize my HP printer and the error was that "the printer cannot be contacted over the network" so I spent a lot of time to solve the problem. Finally helped the simplest thing was that I removed this printer in my list of printers and added again using the "Add a printer" Wizard and it worked perfectly!

• RICOH Aficio 1045 Pcl 6 cannot be contacted over the network

  I am running Windows 7 Pro 64-bit and I try to install a printer multifunction Ricoh Aficio 1045 on a network. I was able to do a typical "add a printer" and everything seemed fine, but I can't print. When I run the troubleshooting printer I get the following error 'printer RICOH Aficio 1045 Pcl 6 cannot be contacted over the network. He said to contact my system administrator. I don't have a system administrator. I'm open to any ideas on this one.

  Printer driver from the site Web RICOH (PLC 6 pilot - worm. 3.1.0.0 r31047en)

• hp 8600 printer cannot be contacted over the network and the printer is not enabled.

  hp 8600 printer cannot be contacted over the network and the printer is not enabled.

  the HP software installed on the PC on the floor. Print wireless from PC upstairs and the PC in the basement on the network for the last month up to yesterday

  Now to receive above - two error messages cannot be contacted ove RL network and the printer is turned off.

  Reality - the printer IS on and the PC on the floor can print to the printer.  Network on the printer symbol says it is connected to the network.

  a reason any PC in the basement all the cant suddenly find the network and the printer?

  Hello

  The first thing I would do is follow step 6 in this document to set a static IP address: http://support.hp.com/us-en/document/c02817031
  When it askes for the DNS information, enter in Google DNS. Preferred DNS = DNS Alt = 8.8.4.4 8.8.8.8

  This could increase the stability of the network connection to the printer downstairs.  If this does not help, let me know what OS is on the computer causing problem, because that could cause a problem?  Other than that, you can check the quality of the signal you get form the network and see if this can be a problem.

• importing data from the old system to the new system, key to the raw16 column

  Hi, experts,
  
  now I have a new system, the design of the system is to use raw (16) column as the key column in all tables of database.
  of course, when the new system goes live (in production), new records of transactions are written to the new database system.
  When the new system inserts new records, it manages itself to avoid any conflict of the raw key column value (16)
  
  
  Now, I'm dealing with this problem:
  
  I need to import data from the old system to the new system, I use sys_guid() to fill the column raw (16) into the new database system.
  How can I avoid conflicts of raw column value (16) between the old system data and the new data of database system?
  
  the sql code I write is very simple:
  
  insert into new_sys_table_a (key_column_raw_16,...,...)
  Select sys_guid(), old_sys_col_a, old_sys_col_b
  of old_sys_table_a;

  insert into new_sys_table_a (key_column_raw_16, col1, col2 )
  select key_column_raw_16, col1, col2
  from old_sys_table_a;
  

• Import data from the text file to open the Document

  This should seem simple, but I can't find a way to import a text file delimited to tab automatically on opening the document.  I can open my form fill pdf document, select Forms > more form Options > data management > Import Data > change the bottom right "Text (*.txt) files" file type, select the file, then import with no problems.  I can't find a way to do this automatically when the document opens.  I know a *.fdf file will do, but my data are in a tab delimited text file.  If this is not possible, is there a program or a script that will convert *.txt to import *.fdf?  Thanks for your time.  Steve

  Have you looked at using custom JavaScript?

  importTextData

  You will need to work on how the data file select the line form.
