How to enable parallel port DC5800

This PC has header pins on the motherboard for a parallel port and I have connected a header cable but linux does not recognise that the computer has any parallel port hardware. There also seems to be no way to enable or disable the parallel port in the BIOS although it does have a setting for the printer port mode. The parallel support is described as "optional" on this PC, is it possible that the port cannot be enabled on this model?
Additional: I just installed Windows and it's the same. It really seems like the parallel port is disabled at BIOS level and cannot be activated.

What kind of hints are needed in order to invoke multiple db link? As I said - this (distributed PQ across db links) is not supported. PQ needs to run inside a single database.
The only time that PQ runs across servers, is with an Oracle RAC database. But even then, PQ runs inside a single physical database.
If you want to use parallel processing across databases via db links, you need to code and implement that yourself.

  • [865PE/G Neo2 Series] How to correct "Parallel port driver service failed to start"?

    I recently disabled the parallel port in the BIOS (I wasn't using it anyway) to try and free up an IRQ or some system resources, when I installed a firewire controller (which I wanted to have its own IRQ if possible).  Then I periodically started getting this error "The Parallel port driver service failed to start due to the following error:
    The service cannot be started, either because it is disabled or because it has no enabled devices associated with it."  I Googled this, but any info I found either was not applicable or was in incomprehensible techspeak.  I couldn't figure out how to prevent the error from occurring, so for the time being I re-enabled the parallel port in the BIOS--disabling it didn't free up any IRQ's anyway.    I would like to know more about this, however.  Is there a proper way to go about disabling the parallel port so that this error does not occur?   
    Should it be done before installing Windows?  What are the advantages and disadvantages of disabling the parallel port, other than freeing up IRQ's (as I said, it didn't--unless this also happens only upon Windows install?).  Gurus, please respond!

    That was the first thing I tried.  There is nothing called "parallel port service", nor is there any mention of the parallel port in any of the services listed.   I don't know if it is even using any system resources, anyway.  The ECP Printer Port always had a box checked that said "never use an interrupt" anyway. It has no conflicts or sharing.   Maybe I should leave it alone.  It's just that people always mention disabling it in order to free resources.   

  • How to enable HTTPS Port in abap system

    Hello All,
    Hope all are doing great,can any one please tell me the procedure step by step how can i enable https port in my only abap system,is it required to enable ssl also for this?..
    Regards,
    Syed

    Hi,
    For enabling the HTTPS port you need to do alot many things
    At first change the para meters in Rz10
    icm/server_port_0 - PROT=HTTPS, PORT=1443, TIMEOUT=900
    icm/HTTPS/verify_client - 1
    ms/server_port_0 - PROT=HTTPS, PORT=1443
    SE80 - Utilities > Settings > Internet Transaction Sevrer = HTTPS
    and also check SMICM under Services HTTPS is not showing as Active
    and still if you are facing any issue with the port check with the network team/firewall team whether any port is being blocked on the network/firewall.

  • HOW TO ACCESS PARALLEL PORT USING JAVA

    hello guys.. Please Solve my Problem..
    I have to access motor through pc using Parallel Port. I want to know how to program in java to access Parallel Port. So How can i code to access the any Port of Parallel Port. Please Guide me in this..

    well I cannot give a more detailed answer than "use the java comm API".
    http://java.sun.com/products/javacomm/
    http://java.sun.com/developer/Books/javaprogramming/cookbook/11.pdf
    However Java wasn't built to do these kinds of operations, so it may well be that the API does not provide the functionality you need. In that case you may need a native library to do the work for you, which can make things a lot more difficult.

    Hi
    You ask for the best way?
    Well, you have got only one way?
    You need an USB to parallel adapter. Check in the google for some offers.
    I searched in the google and found some good options.
    Maybe this could be a good choice;

    Could anyone help me to enable parallel process in 10g database.
    Thanks in advance.

    >
    PARALLEL_AUTOMATIC_TUNING is deprecated since 10g. It's always true now. PARALLEL_SERVER is related to OPS (prior to RAC) and long time deprecated.
    You enable parallel query with an ALTER TABLE statement like
    SQL> ALTER TABLE SALES PARALLEL;or with a hint like
    SQL> select /*+ parallel(sales) */ * from sales;Kind regards

  • How to access parallel ports using LabVIEW?

    I want to send data to a device which is connected through LPT1.when Iam using serial port write.vi with port number 10(for LPT1) it is giving an error code 37 which means the device not found. whether those vis are only for accessing serial ports? Then how to access LPT1 using LabVIEW?

    Most likely you need to modify your labview ini file to let it know that LPT1 (or whichever) will be controled through the serial port control. See the following link for a knowledgebase answer to this question:

  • My parallel port cannot work on win2000 and new pc

    I was troubled by the reading/writing from parallel port on win2000 for a long time. I had made my programs work on win2000/OLD PC, but i failed with the same programs on win2000/new PC. I tried with the method from the forum, that is, install accessHW and other method from my colleagues. Allways failed. I have to return to an old pc, it work! I think not only win2000/winxp will influence parallel port work, but also pc hardware. My new PC is Dell's GX260SMT with p4 2.4G. Dell's FAE told me that i can not install win98 on the pc due to some limitation of mainboard. Who met the smae issue as mine? How to fix it? Thanks for any help.

    I typically stay away from Dell PC's. I always have problems with them..
    I'm surprised to read that a new PC doesn't support Win-98. Have you / can you try Win-NT 4?
    I can't understand why Win2K would be different with a newer PC. The OS assigns the base address of the parallel port to a typical value of 0378h. This is for LPT1.
    My question would be: Are you having problems with LPT1 or do you have a PCI-based Parallel Port (to add ports)? If so, you cannot change the base address with Win-2K or Win-XP which assigns a PCI base address to the port.
    Can you provide more details as what exactly changes between the 2 PC's. Other than the motherboard and typical hardware (of course).
    How is the parallel port configured?
    What are you doing
    with it, etc?
    Any information that can help figure out a solution.

    JLV

  • Parallel port in windows NT

    I am trying to use the parallel port with labview 4.1 in windows NT.
    Windows NT security doesn't let me touch the parallel port, so my
    application crashes every time that I run my VI.
    Does any one knows how to access parallel ports in Win NT ?
    Thank you very much,

    Hello Paul,
    Windows NT does not normally allow direct hardware access, as in
    using LabVIEW's IN and OUT VIs.
    The In and Out work under Win95. There is a third party tool call:
    Peek/Poke 5.0 from Viewpoint. http://www.viewpointusa.com/peekpoke.html
    I have use this software to control Pc hardware. The Peek/Poke software
    gives you In and OUT VIs (that "get around NT security") that work under
    NT.
    I do not know if Peek/Poke works with LabVIEW 4.1, but I do know
    that LabVIEW 5.1 does.

  • How to enable the S-Video port on a Satelite M30X-154?

    Hey does any one know how to enable the S-Video port on a Satellite SM30X-154 laptop?
    If I press the FN+5 keys the only options I get is LCD and no S-VHS option. My TV is set up for it as I watch DVD's through the cable.

    Hi,
    Sorry, my Tosh A100 has a Geforce 7600, I don't know what your GA is.
    But on mine I have a NVidia Control Panel, where I can configure dualview,
    which normally lets me choose between the builtin LCD and the extern monitor (VGA-Port).
    When a TV is connected and not recognized, I can enforce recognition there.
    On the next start of the panel, the TV is then available too.
    Perhaps I could help you.
    If not, note that with windows settings your TV will not be available.
    Try to go to the User Interface of your graphics adapter...

  • How can i us the parallel port of the printer to control a frequenz-generator?

    Hello all !
    I like to  control with LabVIEW 8 student-version, the Frequenz-generator gadget . For this challenge i like to us the parallel port of the printer. I need for data flow only 2 cable. The frequenz-generator gadget need two signal : Low and High.How  can i  us the parallel port of the printer to control a frequenz-generator gadget? I have us  the VIs-Visa  (Visa-Serial, write, Close ), but i dont no what command i have to write on the Visa-Write so that the Signal can be in the low or high position.
    Thanks

    Hi Jeanjac,
    first, look here:
    http://en.wikipedia.org/wiki/Parallel_port
    to get the port numbering. also, be sure not to leave pin unconected, sometimes you might get an error message otherwise (i remember pin11 has to be always connected or so for windows...)
    second, just run the test panel in MAX and write something to your device to check if it works.
    then in LV, you have to decide to which pin is connected your instrument. in any case you have to address all 8 output pins together! this is a parallel...
    if you prefere to use only one pin, then you can use the serial port, with just pin 2 and 3 connected. it would work easier for you, since you address only one bit.

  • How to enable an monitor parallel processing in Oracle

    Hi All,
    I have 2 short questions:
    1. When we want parallel processing, we can either use a parallel hint in the query, or alter a table to be parrallel. My question is what is the difference in the following 2 syntax:
    a. ALTER TABLE myTable PARALLEL (DEGREE 3);
    b. ALTER TABLE myTable PARALLEL 3;
    Does the "DEGREE" keywor make any difference? or they both are same statements?
    2. When we enable parallel processing, how can we monitor oracle processes, to confirm that a certain table is being actually processed by multiple threads of a singe user process?
    An early response would be highly appreciated. Thanks.

    1)The parallel clause lets you change the default degree of parallelism for queries and DML on the table.
    2) PARALLEL DEGREE specifies the number of query server processes that can scan the table in parallel. Either specify a positive integer or DEFAULT which signifies to use the initialization parameter
