java - JVM performance with these garbage collection settings -

-

I have an enterprise-level Java application that makes a few thousand users per day on this weblogic 10.3.6 (Java 1.6 JVM) There is a JACAB web service, using hibernate to hit an Oracle database. It also calls other web services.

We see the following GC settings on our production system: 

  -server -Xms2048m -Xmx2048m -XX: PermSize = 512m - XX: MaxPrimisize = 512m < / Code>  
 What is the effect of this GC sizing? The hardware has more than enough capacity to handle it.  
 I know that it sets stack size and paragraph general at a steady level, but what is the effect of it when you finally have to store garbage?  
 It seems to me that this happens less often, but it takes more time to happen. Is it true?  
 
 
 
 It happens less often, but it takes longer when it can be done < / P>  
 It may happen, it depends on the case of your use. You can also see that GC is less in the rare case.  
 A 2 GB pile is not so much and I will use up to 26 GB without worrying about the size of the pile. This size is slightly slower than memory access or more memory is used.

php - how to change mysql_result($res, 0, "url"); to mysqli -

I do not know how to use mysqli_result like in the past. Is this OK? How is right WHERE status = 'popup' and creditsp> = 1 and (CH) from $ res = mysqli_query ($ con, "SELECT` id`,` usrid`, `url` site Lt; cf || cf = 0) sequence by rand () border 1 "); $ Urll = mysqli_result ($ res, 0, "url"); $ Ownerid = mysqli_result ($ res, 0, "Elixir"); $ Citid = mascile_salt ($ res, 0, "id"); Use fetch_assoc on the results: $ line = $ res-> gt; Fetch_assoc (); $ Urll = $ line ['url']; $ Owner = $ line ['nectar']; $ Site id = $ line ['id']; If there are more than one line, then: while ($ line = $ res-> fetch_assoc ()) {// process $ Line}

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...
