java - Orientdb: Warning Msg Your maximum heap size is 3.54GB -

-

Suddenly, I got this warning message on the console:

Warning: Your maximum stack size is 3.54 GB, but Orient DB uses Off-Hap Memory to avoid GC Pauses. In case the Orient DB is running as standalone, we recommend that Oyeretadibi use the small amount of heap memory to use the rest as an off-hape. 512 megabytes have been recommended for the size of the pile size.

I went through config documentation and found very likely systems. For example:
file.mmap.maxMemory
memory .optimizeThreshold (deprecated)

and so on, but I do not know this That's how to set this value.


Can you please specify what is correct) with many instances of value orientdb for a busy server?


Thank you

This message is a little confusing.

1) If you run Orient DB as a standalone server process, then this message is understandable. Orient DD does not need much map memory and the rest (remaining) off-hap memory can be used for most of DB paging. While launching OrientDB, you can set pile size by java parameter -Xmx512M .

2) If you run embedded DB embedded, then this message is not really useful because the Orient DD does not know anything about your remaining application. Unless you have enough off-hp memory, it's okay and you can ignore the message.

3) This message is displayed only when you specify No (Java System) property storage.diskCache.bufferSize .

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
