Re: [xwiki-users] OutOfMemoryError: GC overhead limit exceeded on a new installation

[myname]

Hi,

the last message is in my opinion the important one.
java.lang.OutOfMemoryError: GC overhead limit exceeded 

as far as i know java is telling you that it's spending too much time with
the garbage collection with too little result.

I would recommend to remove the garbage collection parameters from the
arguments and test it again.
If xwiki is working then you can add the parameters again and adjust the
values.

[xwiki-users] OutOfMemoryError: GC overhead limit exceeded on a new installation

[Jared Simms]

Hello,

I've been trying to get xwiki running for almost a week and keep running into 
memory errors. I was finally able to get through the Distribution Wizard 
without having to restart Jetty due to out of memory errors, but am still 
getting the errors when I try to do almost anything in the wiki. The standalone 
installer works great and is much more responsive but I would like to use 
Postgres for the database.

Any suggestions for what I can do to get xwiki to stop the out of memory errors?

Thanks,
Jared

Here's my current config:

OS: Ubuntu 16.04.1 LTS fully patched

Java: 
 - openjdk version "1.8.0_91"
 - OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-0ubuntu4~16.04.1-b14)
 - OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

Jetty: 9.2.14.v20151106
 - JAVA_OPTIONS="-server -Xms800m -Xmx2048m -XX:MaxPermSize=222m 
-Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC 
-XX:MaxGCPauseMillis=100"

Database: PostgreSQL 9.5.3

JDBC Driver: postgresql-9.4.1208.jar



Here are the most recent errors that occurred when I tried to edit my first 
page:

[xwiki-users] Assunto: Re: Velocity not work in HTTP Meta Info

[Julio Brum]

Thank you Eduard, I intend to migrate to the skin Flamingo. But for now, I 
solved the problem, because given the right script to all users (group). It was 
necessary to change the skin momentarily to Flamingo because the script access 
right not appear on the skin Colibri.

Just a reminder that the colibri skin is deprecated and you should focus your

improvements / etc).

Regarding XWiki 8.1, make sure you force clear you browser cache.

Also note that starting with XWiki 8.2RC1, CK is now the default editor and you 
may want to try it out and verify how it works in it.

[xwiki-users] 2 bug on WYSIWYG Editor Module

[Pascal BASTIEN]

Hi,

I found 2 differents bugs on WYSIWYG Editor Module.
I copy/paste "Load on demand using velocity macros" example:
http://extensions.xwiki.org/xwiki/bin/view/Extension/WYSIWYG+Editor+Module#HLoadondemandusingvelocitymacros

On Xwiki 7.0.1, I load the WYSIWYG Editor, I type some words in WYSIWYG tab, I 
underline a word and select source tab  => a end of line is inserted before __ 
charcters. It is the same behavior with strikethrough word.
Any ideas how to fix it?

With Xwiki 8.1, WYSIWYG Editor is loading anymore.

[xwiki-users] Images with wysywig

[Gerritjan Koekkoek]

When our user use the wysywig editor to insert a image

And the user chooses to upload the image from computer


The system will attach the image to the current $doc

But it will insert a link [[image:x.xxx]] where z.xxx is the attached 
filename.


This works fine when page is visited.

But when in BLOG or using {{include reference='docWithImage'/}}


It can not find the link and show the according 'can not find image' icon

Is it possible to automatically insert a image as 
[[image:wiki:space.p...@x.]] (is this called extended reference to 
attached image])


Same for any attached file where user chooses to add a link to attachment (PDF, 
.doc, .xls)

Re: [xwiki-users] saving a page using javascript

[Eduard Moraru]

Hi,

As Vincent mentions, REST is the way to go.

An alternative, though, is to use the save action's URL:
http://platform.xwiki.org/xwiki/bin/view/DevGuide/Standard+URL+Format#HAction:save

Thanks,
Eduard

You should check the XWiki REST API:
http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI

I don’t think there’s any JS API that encapsulate this but I could be wrong.
