Some questions about writing rc.d scripts the right way

Hello everyone,
I'm setting up an environment and have a number of server daemons that I would like to automate the startup of, so I'd like to write some rc.d scripts for them. Now, I could just go ahead and roll my own but I thought I should try to learn the correct way of doing this.
I have already read the wiki page (https://wiki.archlinux.org/index.php/Wr … .d_scripts) and have used the example there as a starting point, I have a working script that starts a daemon. However I have some questions...
How do I handle the case where the daemon's name differs from the running process? Once case I have is to start up a web server for ruby documentation. The process I need to start is "gem server" but what is listed in ps is "ruby ... gem server". Starting works just fine, but when trying to stop it the rc.d script uses "pidof gem" to locate the daemon which fails because there is no such process (it's ruby) so stopping the daemon fails.
My second query is how to handle multiple daemons that differ only in their arguments. I don't think the rc.d script can handle this. I would like to run several of these "gem servers" for different trees of development.
I may be better off in this case just writing my own thing to do it.
Any help and advice appreciated...

Yeah, look elsewhere.
find / -name \*.pid
Edit:  an example:
PIDFILE=/var/run/named/named.pid
It's in a subdirectory, so that the user that BIND runs at, has permission to create and remove the pidfile from that directory.
One thing to bear in mind, when stopping a daemon, is that it might not stop immediately. E.g. lighttpd, when asked to do an orderly shutdown with:
kill -TERM $(pidof -s /usr/sbin/lighttpd) 2>/dev/null
Cannot be immediately checked in the initscript. My erm, workaround for that is to just assume that it got the message

  • Hello , I want to ask some question about ipads \  How powerful is the iPad?  How useful is it for reading books, newspaper or magazines or for surfing the web? Can you identify any shortcomings of the device?   please help me :(

    Hello ,
    I want to ask some question about ipads \
    How powerful is the iPad? 
    How useful is it for reading books, newspaper or magazines or for surfing the web?
    Can you identify any shortcomings of the device?  
    please help me

    it's less powerful than your average computer. THink of it like a netbook but with a better processor.
    It'll do fine for surfing (although if you browse a lot of flash based sites you will need to get a third party browser since safari doesn't accommodate it)
    You may do OK on reading books, papers or magazines, especially if they have apps, but the ipad's screen is backlit, so it doesn't work well outdoors and you may need to fiddle with the brightness so that you don't get eye strain (it's just like doing too much reading from a computer screen)
    I would say the biggest short comings are data transfer. Apple's preferred work flow is that everything is done via iTunes or the internet....well people dont' always have 100% reliable always on internet access so you can find yourself in a situation where you can't get things on/off the iPad.
    By and large, it's a good device for day to day stuff, but is not a computer replacement.

  • Question about product variable - is BC the right choice for me?

    I have a criteria that must be met for my ecommerce solution for a new business. The customer has a product that has a variable length, and would like the price to reflect the options that are offered. For example: the produced panels are 30" wide, but the customer can choose the length of each panel. Another option may be sq. ft. for material...
    How can I achieve this with Business Catalyst? Is there an easy way?
    Thank you for your time!!!
    Matt

    Look into Product Attributes.
    You can preset various sizes and change the price based on the size. See this KB Article.
    I would recommend creating a trial site, use a template, then try Product Attributes and see if it does all of what you need.
    If you believe it would work then you can go from there.

  • Some question about communicating the usb RAW device

    I have some question about USB communication: I want to make my VI communicate
    TI-DSP by USB, now, the driver of USB on DSP have done, and  there are a test
    program writen by VC and a driver fold(with a .inf and a .sys files), when I
    install the driver and run the test program, the driver program on DSP run
    regularly. And then I want to program a VI which have the same function as the
    test program, so I unload the driver on PC firstly, then install the DSP in
    NI_VISA according to "Using NI-VISA 3_0 to Control Your USB Device - Tutorial -
    Instrument Drivers". When I sent the standard control request using the VISA test panel, the status below happened. I don't know what wrong with my step.

    This thread
    contains already a related answer and explains what a sys driver is.
    While you could theoretically use the Call Library Node to call all the
    necessary Win32 API kernel functions to connect to a device driver,
    this would be very cumbersome and not doable without a real good
    understanding about C programming. Writing an interface DLL instead
    won't need more C programming knowledge at all but will give you a
    clean interface to that device driver which eventually could be used in
    other programming environments as well.

  • Some questions about the integration between BIEE and EBS

    Hi, dear,
    I'm a new bie of BIEE. In these days, have a look about BIEE architecture and the BIEE components. In the next project, there are some work about BIEE development based on EBS application. I have some questions about the integration :
    1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?
    2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?
    3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?
    4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?
    could anyone give some guide for me? I'm very appreciated if you can also give any other information.
    Thanks in advance.

    1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?You, shud consider OBI Application here which uses OBIEE as a reporting tool with different pre-built modules. Both 10g & 11g comes with different versions of BI apps which supports sources like Siebel CRM, EBS, Peoplesoft, JD Edwards etc..
    2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?Its independent of any soure. This is OBIEE modeling to create RPD with all the layers. If you build it from scratch then you will require to create all the layers else if BI Apps is used then you will get pre-built RPD along with other pre-built components.
    3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?BI apps comes with pre-built ETL mapping to use with the tools majorly with Informatica. Only BI Apps 7.9.5.2 comes with ODI but oracle has plans to have only ODI for any further releases.
    4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?User will still see old data because its good to turn on Cache and purge it after every load.

  • Some questions about the U2 edition

    After a long time, I have decided that I will buy the Ipod U2 edition. I really need some information about this model
    Apart from the look, is there any different between the U2 version and the normal one ?
    Will I have all U2 songs if I purchase it ?
    Im currently living in Vietnam, is there any ways I can buy an Ipod ?
    thx in advance!

    1. No.
    2. You can get a 30-minute U2 video from the iTunes store with a coupon provided with the purchase of an iPod U2; this video is not available in Vietnam, as there isn't an iTunes store for your country. Aside from this coupon and the different appearance of an iPod U2, there aren't any benefits to choosing this specific model.

  • Some questions about configuration in MAX.

    Hello,everyone!
    I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
    I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
    My question as following:
    1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
     If I select stepper,though motor can work but I can't test encoder in MAX.
    2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
    3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
     My English is poor,Pls pardon me!I come from China.
    Thank you for your help!

    Hi,Jochen,
    Thank you for your kindly help!
    The manufacturer of the drive and motor that I am using now is Japan SANYO DENKI,drive type is RS1A01AA,motor type is R2AA06020FXP00.
    And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
    Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
    1,Motor can't run.
    2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
    Except for the  two points mentioned above,"Following Error" is  occured frequently,I don't know why.
    I am still not clear why I must set the motor type be stepper in MAX .
    And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
    I am verry sorry I have too many questions!
    I am very appreciate for your kingly help!Thanks again!

  • Some questions about javacard 2.1.1 and smartcardio

    Hello i have some question about java card 2.1.1 and the smartcardio package.
    1.) I want to sign a message with the Signature.ALG_RSA_SHA_PKCS1 algorithm. I use the following code in the applet to sign the message:
    final static byte P1_CREATION_MODE = (byte) 0x01;
    final static byte INS_SIGN_MODE = (byte) 0x60;
    final static byte SmartCard_CLA = (byte) 0xB0;
    private void signMessage(APDU apdu) {
            byte[] buffer = apdu.getBuffer();
            byte byteRead = (byte) (apdu.setIncomingAndReceive());
            signature.init(privateKey, Signature.MODE_SIGN);
            short length = signature.sign(buffer, ISO7816.OFFSET_CDATA, byteRead, buffer, (short) 0);
            apdu.setOutgoingLength((short) length);
            apdu.sendBytesLong(buffer, (short) ISO7816.OFFSET_CDATA, (short) length);
            apdu.setOutgoing();
        }On the host side I use the following code to connect to the card and to send the sign apdu:
    if (TerminalFactory.getDefault().terminals().list().size() == 0) {
                LOGGER.log(Level.SEVERE, "No reader present");
                throw new NoSuchCardReader();
            /* Select the first terminal*/
            CardTerminal terminal = TerminalFactory.getDefault().terminals().list().get(0);
            /* Is a card present? */
            if (!terminal.isCardPresent()) {
                LOGGER.log(Level.SEVERE, "No Card present!");
                throw new NoSuchCard();
            /* Set the card protocol */
         Card card = terminal.connect("*");
            ATR atr = card.getATR();
            LOGGER.fine(getHexString(atr.getBytes()));
            LOGGER.fine(getHexString(atr.getHistoricalBytes()));
            CardChannel channel = card.getBasicChannel();
            CommandAPDU cmd = new CommandAPDU((byte) 0xb0, (byte) 0x60, (byte) 0x01, (byte) 0x00, new String("datadatdatadata").getBytes(), (byte) 0x40);
         ResponseAPDU response = channel.transmit(cmd);
            card.disconnect(false);But this does not work and i got the following error

    2) What is PKCS? what is the difference between
    PKCS#11 and PKCS#15??PKCS is the abbreviation of "Public-Key Cryptography Standards"
    PKCS #11: Cryptographic Token Interface Standard
    See http://www.rsasecurity.com/rsalabs/node.asp?id=2133
    PKCS #15: Cryptographic Token Information Format Standard
    http://www.rsasecurity.com/rsalabs/node.asp?id=2141
    If you want to use yor smartcard as secure token it doesn't have to be a JavaCard.
    BTW: I don't remember a way to access PKCS#15 tokens on a JavaCard from within an oncard JavaCard program. If you want to use keys in your oncard program, you have to transfer it onto the card or generate it oncard and export the public key by your own oncard/offcard code.

  • Some question about fade in // fade out by hideEffect and showEffect in Actionscript

    Some question about fade in // fade out by hideEffect and
    showEffect in Actionscript
    Please kindly take a look at the following page:
    http://camusmiu.no-ip.com/HounganQuestion/PictureHolderTest.html
    (can view source)
    I tried to make an image preloaded and scale the image to
    it's preferred size.
    When I came to consolidate the stuff into a component, I
    found the application goes weird as I implementation the show/hide
    effect.
    The third trial which just hide and show the images directly,
    instead of using viewstack, fail to bring the second image onto
    screen.
    It just used fadeOut instead of fadeIn(you see there is a
    flash of the second image)
    After some study of showEffect and hideEffect behaviour,
    seems the mechanism of hide/show a component works in this way:
    this._fadeIn:Fade = new Fade();
    this._fadeIn.alphaFrom = 0;
    this._fadeIn.alphaTo = 1;
    this._fadeIn.duration = 1000;
    this._fadeOut:Fade = new Fade();
    this._fadeOut.alphaFrom = 1;
    this._fadeOut.alphaTo = 0;
    this._fadeOut.duration = 1000;
    Component_A.visible = true;
    Component_A.setStyle("showEffect", this._fadeIn);
    Component_A.setStyle("hideEffect", this._fadeOut);
    then when I set Component_A.visible = false, the sequence
    works like following:
    Component_A.visible = true
    Component_A.visible = true, alpha = 100;
    Component_A.visible = true, alpha = 50;
    Component_A.visible = true, alpha = 0;
    Component_A.visible = false;
    The above sequence works visa versa as:
    Component_A.visible = false;
    Component_A.visible = true, alpha = 0;
    Component_A.visible = true, alpha = 50;
    Component_A.visible = true, alpha = 100;
    Component_A.visible = true;
    (Correct me if i am wrong)
    ========================================================================================== ====
    From what I observe from the application, I have two
    question.
    1) When more than one component using the this._fadeIn,
    this_fadeOut as the hide/show effects, the component in instance of
    this._fadeIn? will it mess out if more than one component using the
    fadeIn instance in the same time?
    2) from the third component, i.e. PictureHolder3, when I load
    other the picture , it fade out the new image instead of fading
    in... Seems there is problem if I hide show too frequent. I think
    when I hide then show right the way, the component only do the hide
    part...
    Can someone pls look into it and tell me what I did wrong?
    Cuz in normal practice I don't think appropriate to use ViewStack
    in Actionscript...

  • It does not cover my question about in what order does the sync work?

    It does not cover my question about in what order does the sync work?
    Does the first signed on computer copy its information to the cloud?
    Does the second computer/pad/cell then download the information from the cloud overwriting the information on the second device even if some of the information is different?
    What happens to the information on the second device that is not in the cloud?
    If you delete a record (eg a bookmark) from the second device how does it then delete it on the first device?
    What are the keys to the different types of information?

    Hi I have answered you questions inline below:
    Does the first signed on computer copy its information to the cloud?
    Yes when you first set up the account or when you first add a device to the cloud, if it is not the first time, it will merge with the other data
    Does the second computer/pad/cell then download the information from the cloud overwriting the information on the second device even if some of the information is different?
    By default it merges. There is no option to change this.
    What happens to the information on the second device that is not in the cloud?
    It will sync at the next sync interval if that data is selected to sync.
    If you delete a record (eg a bookmark) from the second device how does it then delete it on the first device? What are the keys to the different types of information?
    It resolved the entry the next time the first and second device syncs. Can you elaborate on the second part of this question?

  • Some question about 9iAs R1.2.2 & R2, need your help:

    Some question about 9iAs R1.2.2 & R2, need your help:
    Since 2000, we has used 9iAS Core (R1.2.2) to publish our website. The platform is Suns Solaris (SPARC). The database is Oracle 8i. But there are so many questions:
    1.     The Web Cache cant be installed well
    2.     The web pages use JSP to query database with SQL show errors when we refresh the page a few times. The error will disappear after restarting the 9iAS or refreshing the page again. On the other hand, the same pages dont show error on resin. The error is java.sql.SQLException : Closed Connection: next. I supposed that the connection of database has some hidden troubles, but I can find it, could you give me some advice.
    Now I have installed 9iAS R2, But when I visited the manage page, I found that a password is needed to visit the web cache manage page. I dont think I have set the password, and then I cant control the web cache. I want to know is a default password occurred? If not, what is the password.

    The default password for Web Cache is: administrator
    See walkthrough on the sample code page: http://otn.oracle.com/sample_code/products/ias/content.html

  • Some question about Toshiab reocvery disk for Satellite P300-133

    Hello guys ,
    I got some questions about unpleasant recovery surprises :
    *1)* I just made recovery DVD using Toshiba Recovery Disk Creator and it initially asked for 2 DVDs - but when the first one was done it didn`t require a second blanc DVD . Is it possible all system files of Windows Vista to be written on 1 DVD ?
    *2)* Could I reinstall Windows Vista using the HDD Recovery option ( by pressing F8 ) without using recovery DVD ?
    *3)* Which HDD partitions`ll be formatted ( just system C: or both C: and E: ) using HDD recovery ?
    *4)* What is recovery DVD - Image of the hard drives or Vista installation files ?
    Its pretty bad idea not to include OS on DVD when I have paid for it.
    Thanks for all the problems to Toshiba :(

    1. I think the recovery disk creator means 2 CDs. I have a Portege M700 with Windows Vista and one DVD too. I recovered it and after this I have a clean Vista installation with all drivers and tools from Toshiba. Nothing is missing.
    2. Yes, you can reinstall Vista using the HDD Recovery option when you press F8 at startup. You dont need the recovery DVD but you should create one when your HDD get some errors or something else. If you need a new Recovery DVD, you have pay for one.
    3. The complete HDD and partitions will be formatted, so backup your data first on a DVD, external HDD, USB stick or something else.
    After the reinstallation you have the factory settings.
    4. The recovery DVD is an image of the HDD about the factory settings. If you make a recovery, there are all drivers and tools already installed. Of course on the disk are the installations files of Vista, but you can only use this DVD on your Satellite P300. The disk can not be used on an other Satellite or on a PC.
    When you have more questions, have a look in the user manual. There are a many in formations about the recovery. Its in chapter 3.

  • Some question about Cisco Prime Infrastructure

    Dear all
    I have some question about using Cisco prime Infrastructure:
    - Can I show how many user access to one Access Point (AP) ?
    - If I can. What is display information of user ? etc Ip address, MAC, username access, name of device (notebook, tablet, phone ..)
    - How many time do Cisco Prime Infrastructure refesh user  informantion .?
    Please help me and send picture about it if you can.
    Thank you so much.

    Hi,
    I don't have the Prime Infrastructure to post you image, but you can simply find all the answers you want on the config guide:
    http://www.cisco.com/en/US/docs/wireless/prime_infrastructure/1.2/configuration/guide/clientmgmt.html#wp1232242
    1- You can surely find how many clients associated to a specific AP.
    - Informaiton of the client usually includes username, SSID, ip address, mac address, RSSI, device vendor...etc. I don't think it contains the device type (ipad or iphone both appear as apple vendor. it does not destinguish between this and that.
    3- The time of the refreshment is configurable. You need to configure the corresponding background task for the poll period. (this is also metnioned in the link above).

  • Some question about georaster?

    Hello,
    I have some question about how to create high efficiency georaster model. I have 3T capacity raster data. It's bands is from 8 bands to 12 bands and the resolution is 0.5 meter. In order to ensure the original information of raster data, I consider not use the SDO_GEOR.mosaic, this means that a import file is a georaster object. I keep the original data capacity, not compression. I use JPEG-B to compress pyramid data.
    Does anyone can tell me my georaster model is OK? or tell me some areas for improvement.
    Thanks who have lool my page.

    i don't have specific performance number on georaster using bigfile tablespaces. "A bigfile tablespace with 32K blocks can contain a 128 terabyte datafile" and should be doable with georaster in considering your data size is just 8 TB. It should have some advantages over small file tablespaces, for example, it would be easiler to manage because it has only one datafile. but note, "Bigfile tablespaces are intended to be used with Automatic Storage Management (ASM) or other logical volume managers that supports striping or RAID, and dynamically extensible logical volumes". "Using bigfile tablespaces on platforms that do not support large file sizes is not recommended and can limit tablespace capacity." please refer to the Oracle Database Administrator's Guide.
    thanks

  • [Urgent] Some questions about Oracle Portal 10g - 11g upgrade

    Dear friends,
    We are under doing upgrading assessment of Oracle Portal from 10g to 11g. After reviewed the 'upgrading guide', we still have some questions as below:
    1. Whether the 'Instant Portal' feature remain in Oracle Portal 11g? If yes, how to migrate the Instant Portal 10g sites? If no, any workaround?
    2. Whether the old 10g Page Group and Pages will be still available after 11g upgrade? Also can customer import the old 10g transportset into Portal 11g?
    3. How about the customized Portal 10g objects (such as customized template, style, attributes) after 11g upgrade? Still be usable?
    4. Customer use PDK to develop many portlets in 10g. Can they use JDeveloper 11g to migrate their old project to 11g automatically?
    Thank you in advance and any comment are welcome.

    1. Whether the 'Instant Portal' feature remain in Oracle Portal 11g? If yes, how to migrate the Instant Portal 10g sites? If no, any workaround?Instant Portal is not available anymore in Oracle Portal 11g. The Instant Portal page groups will be migrated to standard Portal page groups. Maintenance of the Instant Portal can be done with the standard Portal tools. The Instant Portal tools are not available anymore.
    Whether the old 10g Page Group and Pages will be still available after 11g upgrade? Also can customer import the old 10g transportset into Portal 11g?Old 10g Page Groups are migrated to Portal 11g. They will still be available after the upgrade.
    Export/Import through transports sets has always been limited to instances of the same version. It is not supported between versions as documented in the Administration Guide :
    [11.2.1|http://download.oracle.com/docs/cd/E14571_01/portal.1111/e10239/cg_imex.htm#CCJBCCGD] System Requirements
    Before exporting and importing content, ensure that your system meets the minimum system requirements, as described in this section.
    Notes:
    * Export and import functions only within the same release of Oracle Portal and the same patch release, for example, release 10.1.4 to release 10.1.4 or release 11.1.1 to release 11.1.1. You cannot export and import between two different releases, such as release 10.1.2 to release 10.1.4 or release 10.1.4 to release 11.1.1.
    How about the customized Portal 10g objects (such as customized template, style, attributes) after 11g upgrade? Still be usable?Customized objects get migrated as well. Certain types (e.g. PL/SQL item types) need to be checked after upgrade as the behavior of the PL/SQL code may differ between database versions. This is particularly of concern when the 10.1.4.x Portal uses a 10.1 database. A database upgrade to either 10.2, 11.1 or 11.2 is necessary as Portal 11g is not supported with RDBMS 10.1.
    Customer use PDK to develop many portlets in 10g. Can they use JDeveloper 11g to migrate their old project to 11g automatically?Never done this, but the Portal framework is able to consume JPDK providers which are running in older versions of the toolkit. If the providers are running in standalone OC4J containers, you would be able to upgrade the framework and keep the providers in their OC4J containers. This will allow you to focus on the framework first and worry about your providers later.
    Thanks,
