Oracle – Randomly got ora-01017

I installed an Oracle RAC (12.1.0.2) on ESXi 6.5. RAC nodes are hosted on different physical servers, and there is storage on which the shared hard drive resides.

Here is my problem:
Try Toad, sqlplus, Weblogic. The creation of a data source is irrelevant. With each method, Oracle reports ORA-01017 errors, almost 50% of my attempts.

I am unable to run my software, user interfaces, services, etc., as I usually cannot connect. Here are my connection examples to sqlplus:

I suspect an entropy value, but I really don't know what to change.

cat /proc/sys/kernel/random/entropy_avail generally outputs around 3000

ERROR:
ORA-01017: Invalid username / password; Registration refused

As you can see, this error occurs with the same user (on the database node itself. It is not a remote computer).

Waiting for your valuable suggestions,

Thank you very much

Uploads – WordPress multisite images randomly receive 404 errors

We have a WordPress multisite and the images on the subsite randomly receive 404 errors (not all). If you upload multiple images to the media library, some will work fine while others will get 404 error. This is very confusing. It is not caused by plugins or themes and I also reinstalled WordPress.
Images that receive 404 must also be renamed for uploading to work again. Does anyone have any idea why this is happening and what is the solution?

magento2 – CSV Uploader randomly throws errors for identical entries

I am trying to upload 12000 SKUs (1000 each) using the CSV uploader.

I get some random errors for identical data.

Example: Each cell in the attribute_set_column column has a 9, but I get this error

 Invalid value for Attribute Set column (set doesn't exist?) in row(s): 575, 577

Is there a way to fix such inconsistencies or get less vague error messages?

Thank you very much

How do I randomly convert Li texts to links in Javascript?

I need to convert a list of Li texts into links using javascript, 3 links at random.
SEMrush

FROM THAT:

  • List 80
  • List 82
  • List 100
  • TO THIS:

    I have batch overflow search everywhere but can't find anything that fits my needs.

    Something like that:

    • List 1
    • List 2

java – Tries to randomly generate enemies every second from an array list, but nothing is shown

I'm currently doing a Space Invaders / Astroids game and working on random enemies that range from the top of the window to the bottom. I thought it would be best to use time, but so far it doesn't seem to work. Is there any way I could do it better?

int time = second();


counter = counter - time;
   if(counter == 0) { 
    ObjEnemies enemy = enemies.get(counter);
    enemies.add(new ObjEnemies((random(height)), 0,20));
     enemy.move();
     enemy.display();
     counter = 1;
 }

Function construction – If statement with randomly generated integers

I have to do the following:

Write a Mathematica function called randomHop that uses a list of two x and y coordinates as an argument. Your definition should begin

randomHop ({x_, y_}): =

The function should then generate a random integer r equal to 1 or 2 (this should be localized) and then

  • If r equals 1, return {{0.5, 0.5}, {0.5, 0.5}}. {x, y};
  • if r is 2, return {{-0,5, -0,5}, {0,5, -0,5}}. {x, y} + {1.0, 0}.

I have tried so far

randomHop({x_, y_}) := (
  r = RandomInteger({1, 2})
  If(r == 1, Return({{0.5, 0.5}, {0.5, 0.5}}.{x, y}), 
  Return({{-0.5, -0.5}, {0.5, -0.5}} . {x, y} + {1.0, 0})))

but it does not work and I do not know why. Any help would be appreciated.

sharepoint online – InfoPath forms are randomly stored as XML

I have a bunch of InfoPath form libraries. All three libraries use InfoPath client forms. The forms contain parameterized queries so they can not be converted to forms based on Broswer. The problem is that some users can successfully open, edit, and save their InfoPath forms in the library, but others have trouble saving the form – the form is saved as an XML document and becomes unreadable. Has anyone else seen this behavior and have a diagnosis for it? In some cases, some users have warned me that they have received the error "Before you open files from this location, you must first add the site to your list of trusted sites …", but I have no confirmation that this happens in any case. I can not duplicate the error myself, but access the system as an administrator of the site collection.

java – Bauschlachtschiff in progress. How do I connect the ships and locate the ships randomly?

I have been working on this side project for some time trying to make a battleship game. I came across some things that I do not know how to do. I wondered if anyone knew how to make each of the five ships of the appropriate length and then randomly determine the position on the boards.

I draw the two boards so in my void setup ()

 //drawing grid
  for(int i = 0; i < 10; i++){
     for(int j = 0; j <10; j++){
      squares.add(new ObjGame( 20+50*i,75+50*j));
      squares.add(new ObjGame( 580+50*i,75+50*j));
     }
  }

Here I create the matrix for the ships and the hit symbols. I do it in their own class to try to somehow keep my lead person clean

ObjGame(int xi, int yi){
   ship = random(5)<.5;

   x = xi;
   y = yi;
 }
  void draw(){
    pushMatrix();
        translate(x,y);
        fill(25,200,222);
        stroke(c1,c2,c3);
        rect(0,0,50,50);

        if(!ship && clicked){
         fill(255); //white circle for miss);
         ellipse(25,25,30,30); 
        }
        else if(ship && clicked){
          fill(255,0,0); //red circle for hit
          ellipse(25,25,30,30);
        }
        else{
          fill(25,200,222);
          rect(0,0,50,50);
        }
       popMatrix();
      }

      void attacked(){
        if(mouseX <= 500){
        if(mouseX> x && mouseX< x+ 50 && mouseY > y && mouseY < y+50){
         clicked = true;
         println(x+" "+y);
        }
      }

I also try to print out their coordinates, but I want them to print 0-9 instead of their actual x and y coordinates. Is there an easy way to fix it, or should I just switch it?
