Hi
I am still learning about xwiki (how to code velocity, code/add plug-in
etc) so wanted some real data.
I will install mysql and ask for sql dump as Sergiu suggested.
I will add a few notes as Comments to Import/Export and Download pages!!
Many thanks!
Ajdin

Xwiki would not start with heap size more than 1.6gb, I've attempted
this.
I'll try the other option you've suggested although I do not know how
to load sql dump into HSQLDB? I've you have any suggestions please
advise.
One warning: You should definitely not use HSQLDB for anything more than
demo purpose. It's not a production database.
Thanks

I searched web for 2 days looking for answers to this question and all
I found was JAVA_OPTS and CATALINA_OPTS suggestions.
I have not seen
any ware your comment on "handling attachment consumes about 27 time
the size of the attachment". It was probably some ware out there but
I missed it.
Maybe you should include it on the Import/Export page
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/ImportExport
Thank you for your response, at least I know where the issue is.

Hi All
I am having a problem uploading a xar file. I get "Java Heap Space,

I have changed file upload size to 133MB by going to
http://localhost:8080/xwiki/bin/edit/XWiki/XWikiPreferences?
editor=obj
ec t and changing Maximum Upload Size:.
The .xar file is 90MB downloaded as backup from
http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/Main/
WebHome.
I do not know what version this runs on since it is on one of the
xwiki farm things :-).
I have Win XP with 3.5gb memory available.
Has anyone had this error recently?
This is a major design flaw of the current attachment storage model.
As
stated in a previous mail, handling attachment consumes about 27 time
the size of the attachment, so 90M * 27 ~= 2.5G. This needs to be
fixed ASAP. In the meantime, you can either increase the heap size to
more than 2.5G, or request an sql dump from the myxwiki farm admins.
