Question about the listener and the process server in dedicated server mode

Hello

The Oracle documentation says that, when a client connection request is received on the server, the receiver creates a process server who will work with the database instance to perform the tasks requested by the user/client process. So far, everything was good.

Now, when the user is on the Oracle himself server, the listener didn't need to run to establish a connection to the database. Therefore, it is possible to stop the Listener and not always connect using sqlplus and a valid username and password.

In the case above, the question is: if the listener does not work, what/who created the process server that communicates with the instance of the database on behalf of the user? In other words, in the normal case, the listener could get the request and create the server process. When the listener does not work what part of the Oracle Gets the requests and creates the server process?

Clarification on how this case is handled are very much appreciated, thank you,

John.

John,

I guess that you have asked the same thing in a different form in another thread. In the case, when the process of the user and the server is to be on the same side, the communication done by using the Protocol bequeth and the user, since it is not not going to use a (@) sign, he would use a default service for connected sys$ users .

  • Questions about the process of cloning in Oracle Apps

    Hello..

    I'm trying to clone Oracle 11i (single node) Linux applications, but with some doubts in the process... could someone please help me...

    I ran preclone (adpreclone.pl) scripts on both layers of DB and APPL system source... then stop apps services and target the database copy in the system... but my question comes here... they say I should be copy only files of the SUMMITS as APPL_TOP, COMN_TOP, etc. and ORACLE_HOME, IAS_ORACLE_HOME... but these TOPS and HOUSES exist within a directory as...
    example:
    APPL_TOP - / dev/p01/oracle/devappl
    COMN_TOP - / devc/p01/oracle/devcomn
    ORACLE_HOME - /dev/p02/oracle/devdb/9.2.0
    by note metalink (230672.1), they say it's to copy...
    [APPL_TOP]
    [OA_HTML]
    [OA_JAVA]
    [OA_JRE_TOP]
    [COMMON_TOP] / util
    [COMMON_TOP] / clone
    [COMMON_TOP] / _pages (if this directory exists)
    [806 ORACLE_HOME]
    [iAS ORACLE_HOME]
    My question is should I be creating directories like (/ dev/p01/oracle/devappl) (/ dev/p01/oracle/devcomn) and copy the TOPS and HOMES in appropriate subdirectories or just simply copy... then run the process... postclone your ideas and suggestions are welcome... Thank you...

    your right... that's the real way, manually create the directories and copy them from the source to the target by the metalink (230672.1) note... but I'm worried that I might miss some files in the copy process... I mean are below here are the the only ones required in the process postclone... because if you see the real $ORACLE_HOME (/ dev/p02/oracle/pixdb/9.2.0) to the user oracle is missing... What about the database files? .. .is there all I could mention to facilitate the creation of directories...

    You can just copy the files in the directories devdata, lolo, devappl, devdb, devcomn.

    Also all by creating the directories in this way... If I'm going to use a new name for the instance, do I have to replace the "dev" to the new name as 'edev' or something and then start the postclone process...
    /dev/P02/Oracle/pixdb/9.2.0
    /dev/P01/Oracle/pixora/8.0.6
    / dev/p01/Oracle/pixora/IAS
    / dev/p01/Oracle/pixappl
    / dev/p01/Oracle/pixcomn

    You can use any name for the main mount (it is-to-say/u01 /... or/edev /..), just replace dev with edev for five above mentioned directories.

    Thank you

  • Question about the process() in Lession 1-2 method

    Lesson 1-2 contains the statement "String r = process (list, (x, y)-> x.length () - y.length ())", that I do not understand and cannot parse, even if I am a little familiar with lambda expressions. "  The method takes a list of String and a comparator, but the result is assigned to a unique string.  What result returned by this method?

    Looks like you are looking to slide 4 lesson 1-2.

    The example here does not say what the process() method, but one can imagine that she's going through all the items in the list and chooses the one that is the largest according to the provided comparer. This is similar to the Collections.max (Collection, comparator) method. Who is?

    Furthermore, there is a small error in the declaration of the process() method which could give a little trouble. The statement must have a parameter of type:

    static T process(List l, Comparator c)

    If you have problems, the analysis of the code, the line in the example is

    String r = process(list, (x, y) -> x.length() - y.length())

    In this case, the reference parameter is the lambda expression

    (x, y) -> x.length() - y.length()

    This has two parameters which, in this context, must be of type String. The Agency calculates the difference between the lengths, which is an int. Thus, the lambda takes two strings and returns an int. This corresponds to the comparator interface compare() method.

  • Question about the use of merger during cloning modes

    Hi I want to clone to an empty layer above the background layer. I have the tool set to curent and below and the white layer is set to the normal blending mode.  I want cloning to be in darken blending mode. I have change the blending mode of the Clone Stamp tool to darken. Who will work on a blank layer that is set to normal or is it necessary to also change the blend mode of the Virgin to darken so layer? Thanks for your help.

    I don't think changed for the Clone Stamp tool in cs5 compared to previous versions.

    You should be able to use the Healing Brush tool on an empty layer and vary the blending modes in the options toolbar.

  • A few questions about the use of data and Cliq

    I have the cliq, however I chose to not get 3G (so I bought full fare). So I have a few questions about the phone and the use of 3G / 2 G/Edge:

    1 - is possible to disable completely the 2G / 3 G/Edge? I know you can switch between them, but are anyway just tell the phone to stop using them altogether since I'm not subbed to the service?

    2. when the update takes place, I guess we'll have to reconnect motoblur and etc, but if I don't have 3 G will I have motoblur connection problems after the update? Or he keeps the latest wifi settings so that it would connect to wifi to connect. When I first got my phone it was not a problem b/c I had 3G for the first month.

    I hope that makes sense, thanks!

    To stop all the data, I would like to download an application called APNDroid. He cut them all down. When you log on to blur you have 3G or WIFI doe this without getting a timeout error. During the process of setting up your Blur account, you can press the menu button and set up your wifi to work, this will connect you to Blur and your phone will be connected to the blur. If I were you I would be rethinking to do a data plan since you are really losing out on most of your main features of phones. It's your choice, however.

  • Questions about the implementation of clusters of storage and DTS on active cluster

    I have a few questions about the implementation of clusters of data store and SRS storage in VSphere 5.1.

    We have a data center with about 15 HP blades and a few servers non-lame.  The hosts are all either VSphere 5.0 or 5.1.  Our back-end storage is an EMC VNX 5700 with about 20 stores of data.  All the VMWare is managed by VCenter 5.1 running on a dedicated physical machine.

    Currently, each data store is used individually; No piles of data store are put in place.  When a new virtual machine is created, the administrator usually chooses the data with the most space store.  Periodically, we will go back and manually storage vMotion machines to balance the load.

    Recently, we have expanded the VNX storage, so we now have LUNS in different pools, with different levels of performance.

    What I would do is set up for the data store clusters, so that us when a virtual machine is created, the administrator must not know what data store is in which pool.  Also take advantage of the DRS storage so that the burden of storage will be "refine" himself a little.

    I know the setting up of a cluster of storage in a 'clean' environment is quite simple, but my concern is creation/conversion data warehouses existing in active production in the cluster, while they are used.

    If I access the screen "data warehouses and store data from clusters ', right-click on the data center and create a cluster, and then move the various data stores in the new cluster, will there be an interruption in the production running systems?

    I also wonder about activation of storage i/o control.  It is not currently enabled on data warehouses.  I know it's useful for the StorageDRS, but will be allowing any negative impact on the system?  If I turn on the warehouses of data, is there anything else I should do or set in addition to all that allows him?

    Finally, we are in the process of Site Recovery Manager configuration.  SRS has an impact on the configuration of the data clusters and DTS store?

    Thanks in advance for your comments.

    Hello

    Clusters of data and using DTS store doesn't impact RS even if you create a cluster of data store for storage of replicated data and another for everyone else, this way you machines virtual you want to replicate are not moved on warehouses of data that are not replicated , but will still have the ability to move if there is a conflict.

    Gregg

    With all due respect but SRM and DTS don't go together. SRM does not at all support the use of DTS. So if you are configuring SRM forget DTS for now.

    Reason for this is that SRM knows no DTS and VMs can be in flight when a failover should occur, and bad things can happen. Also, the protection breaks when a virtual computer is moved between data warehouses in a cluster data store.

    In short: don't go there.

  • Question about the database to use with ESX and Labmanager

    Hello

    Finally my company is buying a permit for Labmanager and ESX server using Labmanager to our tests.

    We had a question about the database that we use for the actual installation.

    Could we use MY - SQL? Or that we have the olbigation to install a SQL or Oracle DB for the whole system to work?

    We prefer to use MY_SQL because it is open-source and will cost less to use for us.

    Thanks in advance for the answer and please excuse my bad English, I'm french spoke first.

    Lab Manager installs SQL Express as part of the installation and use. If you install also Virtual Center as part of your deployment of Lab Manager (do not use an existing VC server), you can use the database SQL Express is included for small installations of ESX, but MY SQL is not an option. You can search the databases supported in the installation guide for what version you deploy.

  • Question about the interruptions and priming

    Hello

    I had a few questions about the startup and interruptions in a virtualized environment

    Assuming that, plenty of virtualization (no material assistance to virtualization of memory ).

    1 initialization: in an ordinary PC, the boot process starts with the BIOS, to expansion ROM, back to the BIOS and MBR secondary boot record, then grub (is it) and finally the operating system. In a virtualized environment with VMM running directly on top of hardware (Native VMM), how is the initialization of the different process, as I understand it takes BIOS-> Expansion ROM - > BIOS-MBR-> other record secondary-> VMM-> OS--> applications >. Am I right on that?

    2 breaks: VMM examines the source interruptions prior to the interruption, so in a multicore environment, assuming a 2 processor core, how the VMM decides on the kernel for which the interruption in intended, prior to shipment of the interruption. Interruptions are tag ID, said core ID?

    Thanks in advance

Am I right on that?

    It is simplistic but essentially correct.  A metaphor would be a little better thinking that the hypervisor/vmm is an operating system, except that the process on this operating system are requests or comments OSes.  If the BIOS-> OPROM-> BIOS-> MBR-> hypervisor-> init process of the hypervisor-> reviews of fork () s operating systems.  This can become blurred by the design choices (for example Xen/Hyper-V init start a coded parent hard partition that makes hypercalls privileged to fork() guest OSes; ESXi init runs a very limited subset of applications directly on the hypervisor and ESX Classic is somewhere between these approaches).

    There is a subtle distinction between "hypervisor" and "www."  The "hypervisor" is the operating system of single root (e.g. ESX) who interacts directly with the hardware and has access to everything; a hypervisor is not to be used to run virtual machines.  When we talk about a "hypervisor", the tendency is to describe something which is a BONE (although usually a minimal OS designed only to run virtual machines).  The "www" is the layer that allows a virtual machine run: it provides the interposition, virtualization and emulation services and can be plural (for example a vmm by guest operating system).  Architecture of VMware deal with these two separate components, while most other virtualization platforms merge the two.

    Strictly speaking, the interruption is not transmitted to a guest operating system - receives the hypervisor (or rather the VMM it transmits to the hypervisor), the hypervisor drivers interpret the interruption (for example reading package of NIC, I/O process of HBA, the timer tick completion), then after a new appropriate break in the guest OS.

  • Consider purchase of Wacom Cintiq 27 HD Touch - Questions about the tactile feature in Photoshop and Lightroom

    I'm considering buying a 27 HD Touch of Wacom Cintiq monitor. I have a few questions about the two programs Adobe and their use of the 'touch' feature - Photoshop CS6 and Lightroom 5.7 running on Windows 7.

    1 problems related to touch a feature in Lightroom and Photoshop CS6 and 5 resolved that you see on the forums of Wacom a year ago?

    2. If so, is there sufficient value gained through the tactile feature in Photoshop CS6 and Lightroom 5 to justify the $500 price difference between the Cintiq 27 HD vs Touch HD? (I realize that this is a subjective question based on the abundance of its cash).

    3. I intend to stay with CS6 as long as possible to avoid a monthly subscription, BUT I wonder if buy the Touch HD can provide additional key features in future releases of these products that do not exist currently. (It is a pie in the kind of sky in question).

    Thank you!

    Support for Photoshop Touch is added by CC 2014.2.2.  However as the Pro Intuos Wacom tablets with touch can be used with earlier versions of Photoshop and the Wacom Tablets Configurator can custom features can be used with Photoshop touch tablets.  I use LR but I don't know that the same thing would be true for her. You can configure the setting for many applications. The device driver knows which application its interfacing with and uses the parameter set for each...

    I have disable most of touch when using Photoshop.  The main reason why I have a Tablet is Photoshop Brush tools. Like Eraser, clone stamp, etc, nothing is better then a pen when it come to create the layer mask.  For most programs, I always use a mouse and I use the keyboard, the mouse and the pen with Photoshop...

    I never wanted a Cintig I do not have my hand between my eyes and the work. I'm not an artist.

  • A question about the methods and parameters.

    Hey guys, this is my first post here. I am very new to Java and done a bit of C++ before Java. I had a question about the methods and parameters. I do not understand the methods; I know they can be repeated when it is called, but it's almost everything. I also know that a program should have a class that contains the main method. What I really, really understand on methods is what the parameters are. I know they are in parentheses and that is it. Could you explain what they are? I really appreciate it. Thanks to all in advance. Best regards, Michael

    Taking an example:
    Suppose you calculate area of the rectangle you need two inputs one is the length and the width. Area = l X b, where l = length, b = width

    If your method, say, calculateAreaOfRectangle (length int, int width) will be two parameters as arguments.

    System.out.println ("field of rectangle:" + calculateAreaOfRectangle (40,30);)

    public int calculateAreaOfRectangle (int length, int width) {}
    int area;
    Area = length * width;
    return of area;
    }

    So if you call this method then the output will be returned in 120.

    Parameters of a method are simply the input variables for the method of treatment for all calculations or something useful.

    And we cannot have methods inside the main method in Java. It is in the java syntax and if you do, it will throw a syntax error.
