Dynamically change the Init parameters

Hello

We will improve our database 10.1.0.5 to 10.2.0.5.

The database is running on pfile.

SQL > show the pfile parameter

VALUE OF TYPE NAME
------------------------------------ ----------- ------------------------------
chain of SPFile

After you run the tool preupgrade, got the warnings below.
**********************************************************************
Update settings: [update of the Oracle 10.2 database init.ora or spfile]
**********************************************************************
ATTENTION: - > "streams_pool_size" must be increased at least 50331648
ATTENTION: - > "session_max_open_files" must be worn at least 20


I don't find these settings in the pfile file. Is it possible to dynamically change these settings?

Can I add these parameters to the pfile file before the upgrade of the database?

SQL > show parameter of flow

  • Dynamically change the number of sub-panels

    Hello

    I have a computer where usually 4 testplaces of production are connected to.

    I want to have a main VI indicating the status of the 4 different testplaces, that I can do with 4 separate sub-panels - no problem.

    The issue is that I would be flexible in testplaces how I show in a program (as this hole thing is pretty cool, and I expect that some changes will come). Is it possible to dynamically change the number of sub-panels displayed (other that make it twenty of them and turning off then those you don't need)?

    My first idea was to place the school in a table, but unfurtunately is not possible.

  • Dynamically change the path of the report

    Is it possible to dynamically change the path where reports are saved. TestStand 4.1.1

    Glennjammin,

    You can set a path to the specific report for any sequence that you run via the entry points of process model using the reminder of your sequence ReportOptions. It will allow you to change the current settings in the Options report (including the path) for the execution of this sequence. This allows each of your sequences have unique report options.

    If I understand your question, you want to do is exactly what is meant recall ReportOptions.

  • Two quick questions (hopefully) - right way to dynamically change the CSS class and put of Splash screen implemented

    Couple of quick questions have left me speechless!

    So, it seems obvious that many JavaFX applications want to dynamically change the CSS styles.  Is the best way to do it through la.getStyleClass () .add ("classname") < node >?  The underlying data structure is a list of observable.  So let's say we have 5 styles that simply to change the fill color of a circle of 5 different colors, respectively.  So if I have a condition in which I want to dynamically apply 1 of these 5 styles, as I do now it's by setting all 5 styles as a string in a list by using a static initializer, then I call < node > .getStyleClass () .removeAll (list), then getStyleClass () .add ("classname").  I do this to avoid adding again and still the same style and inflate the underlying list.  What is the right way to manage dynamic CSS styles?

    Finally a very simple I think.  So I know there's a little differently to implement a splash screen.  My app has certainly got bigger in the last few months of development and I noticed there are about a 5 second delay between when I run the application when I see the main stage.  I was thinking what a splash screen would be nice to fill that time.  I had no time to prototype using a Preloader and I fear that using another, early stage start-up again would be too long of a delay.  "I actually thought that using the Nice and simple JVM argument" - splash: image name > "would be simple, easy and effective.  Unfortunately when I try to do, the splash screen appears but never goes away.  Anyone know what is happening with this?

    Your mechanism to manage the css style classes is a good approach; I've used several times. I wonder why the style classes have been implemented as a list, instead of a game, but there may be cases of good use for the use of a list.

    In some cases you can also consider using CSS PsuedoClasses, which were presented in JavaFX 8. Here is a little easier to use, especially if you have two options. But a use case might look like:

    public class Message {
        public enum Status { NORMAL, WARNING, CRITICAL }
    
        private final ObjectProperty status = new SimpleObjectProperty<>(Status.NORMAL);
        private final StringProperty message = new SimpleStringProperty();
    
        // constructor, getters, setters, and property accessors....
    }
    
    public Label createLabel(Message message) {
        PseudoClass warning = PseudoClass.getPseudoClass("warning");
        PseudoClass critical = PseudoClass.getPseudoClass("critical");
    
        Label label = new Label();
        label.textProperty().bind(message.messageProperty());
        message.statusProperty().addListener((obs, oldStatus, newStatus) -> {
            label.pseudoClassStateChanged(warning, newStatus == Message.Status.WARNING);
            label.pseudoClassStateChanged(critical, newStatus == Message.Status.CRITICAL);
        }
        return label ;
    }
    

    And then your css looks like

    .label:warning {
        -fx-text-fill: orange ;
    }
    .label:critical {
        -fx-text-fill: red ;
    }
    
  • How do I dynamically change the the number of vCPU and amount of a virtual computer memory?

    Hi all

    My first question is how do I dynamically change the number of vCPU and amount of a computer virtual memory when the virtual machine is running? If so, this may be achieved by writing a few scrpits to inform the hypervisor?

    My second question is, I can start a virtual machine in KVM with the number of vCPUs and amount of memory configured in the startup script. I don't know if this is supported in vmware ESXi?

    I couldn't find the answer in the ESXi 5.0 user guide.

    Your suggestion will be highly appreciated.

  • How to dynamically change the host name in the Pages of the URL of the APEX

    Dear gurus,

    Please advise me on how to dynamically change the hostname in the URL used in the pages of the APEX.

    For example: I have the below URL in one of the apex pages.
    owa_util. REDIRECT_URL ("http://adminlxdb03.texas.org:7780/pls/htmldb ' |' / f?") p ='|| v ('APP_ID') | ": 151:" | " v ('APP_SESSION'));

    in the case of a Migration of this apex from one server to another (for example, TEST the PROD box), this / these pages are wrong because the different host id name in the PROD box.

    Is it possible that we can dynamically change the hostname in the URL used in the pages of the APEX.

    for example
    owa_util. REDIRECT_URL ("http://adminlxdb03.texas.org:7780/pls/htmldb ' |' / f?") p ='|| v ('APP_ID') | ": 151:" | " v ('APP_SESSION'));

    should become

    owa_util. REDIRECT_URL ("http://adminetuxdb09.texas.org:7780/pls/htmldb ' |' / f?") p ='|| v ('APP_ID') | ": 151:" | " v ('APP_SESSION'));

    It's adminlxdb03.texas.org (TEST) at adminetuxdb09.texas.org (PROD).

    If the page has no error...

    Please notify.

    Thank you
    Sheik

    You don't need to provide the hostname while redirecting in the pages of the apex

    owa_util. REDIRECT_URL ('f? p ='| v ('APP_ID') |) ": 151:" | " v ('APP_SESSION'));

    should work just fine.

    is it possible to dynamically change the table used in a select statement for an interactive report 3.2 on 11g database? I have a series of similar tables, one for each month of the year. I want to click a month on one page and to set up a table for this month report. I want to use a page for this report and have all the links from the link to the previous page on the same page, just different results based on what month has been clicked.
    I know I could just install 12 different reports and conditionally display each region based on a value passed to the page, but I prefer to create only a single page and a report on this page.

    Thanks for ideas or solutions.

    Hello:

    Because the tables involved are fixed for a given month, you can try something like

    select * from tab_1
    where :p_mth=1
    UNION
    select * from tab_2
    where :p_mth=2
    UNION
    ....
    select * from tab_12
    where :p_mth=12
    

    only the query for the IR. "P_MTH" is the page element has the value entered by the user for the months for which data should be retieved.

  • Dynamically change the Ni HSDIO channels

    I am currently using a PXI-6552 module to generate and acquire I2C signals simultaneously.  I would like to know if it is possible (and how I would go to this topic) to dynamic change channels.  My goal is just to pass the two references of NOR-HSDIO (purple variables) to a new slot - VI that I create from a different set of 5 channels 5 channels.  For example:

    Pseudocode:

    PXI sessions initialize;

    for (i = 0; i< 10;="">

    {

    Set the channels 0-5;

    Generate and acquire;

    Stop the acquisition;

    Set channels to 6-10;

    Generate and acquire;

    Stop the acquisition;

    Set channels to 11-15;

    Generate and acquire;

    Stop the acquisition;

    }

    close the sessions of PXI;

    Basically, I need the fastest way for acquisition channels without having to initialize and close sessions each time.

    I am currently using the HWC downloaded the example .zip from here: http://www.ni.com/example/31200/en/. (I've also attached the two that are necessary for my problem).

    Init HWC Device.vi: (also attached)

    Performance Device.vi HWC: (also attached)

    I may need on the screws are Assign dynamic channels, Configure Idle State and initial configuration.  However, I don't know if those are the only ones.  If it's possible, can I close the original channels and then assign more?  Or re-call "Dynamic Assign Channels" automatically disables all channels not assigned?  Etc.

    The important things to note: I'll put 5 channels at once - for both acquisition AND generation.   I need to close the channels and proceed with 5 different channels - for both acquisition AND generation.  All channels must be on the State of the 'z' to high impedance permanently.

    If you need further information, please let me know!  Thanks in advance for any suggestions and assistance.

  • Dynamically change the Format of Date of Application

    Hi all

    I am looking for a possibility to change the format of date of Application in globalization attributes dynamically according to the user.

    Something likeAPEX_UTIL.SET_SESSION_TIME_ZONE but for the date format.

    Does anybody know how it works?

    In detail:

    I want dates in interactive reports display in a specific date format.

    If I put the following in the attributes of 'security' - call the virtual private database PL/SQL to define the security context:

    BEGIN

    If password = "MY_TEST_USER" then

    run immediately "alter session set nls_calendar =" English Hijrah "';"

    run immediately "alter session set nls_date_format =" DD-MM-YYYY "';"

    end if;

    END;

    Then, the dates are indicated correctly in reports interactive but not in the Action menu-> filter.

    If I put date_format = "DD-MM-YYYY" in the attributes of the globalization, it works very well in the interactive report filter.

    The problem is that I want to set this attribute only for some users.

    Thank's,

    Kirsten

    (APEX 4.0/APEX 4.2)

    Because you can use string syntax of substitution for the attributes of the globalization, for example, you could create an element of the AI_DATE_FORMAT application, reference & AI_DATE_FORMAT. and fill out the application element according to certain parameters in the code after the authentication of the authentication system (for example: get a parameter of an array of parameters user or somesuch).
