Hi,
A complementary option you may want to try is to split your XAR into smaller
pieces. The XAR is actually a ZIP file loaded with XML representations of
XWiki pages and a descriptor.
Thus you can ZIP say, 20 pages together, look at the description file and
copy it with the right pages included in it, rename the ZIP to .xar and try
importing it.
This way you'll have 5 smaller files instead of a big one, which, in
addition to the steps Ajdin described, should help you get your import done.
As a rule of thumb, given the limitations Sergiu calculated some time ago,
you want your import file to be approximately no bigger than 1/30 of the
amount of memory allocated to your JVM. Thus if you allocate 1.5GB of memory
to the JVM, you'll need your file to be 50MB to maximize your chances of
getting things working.
We're aware of the numerous limitations of the current import / export
feature (max size, pages getting overwritten) and will work on improving it
in the future - once we have achieved our current overarching goal (getting
XE 1.8 out!!).
Hope this helps,
Guillaume

Hi
I'm not sure why you get this error but I do know (since I tried the
same with a 90MB import) that it is pointless trying this with the basic
xwiki setup. Another problem you'll have is the bug with uploading
attachments and doing import is equivalent to adding attachment.
So first of all get Mysql and glassfish or tomcat.
Install xwiki 1.8.
Make sure you have plenty of memory for JVM (I found 1.6 to be the
maximum on windows machine).
Reduce your import file (export without attachments from your live
site).
Then try to import. Then again and again etc.. Until one day it all
works.

Subject: [xwiki-users] Max Upload Size questions
Hello everyone,
I was testing the import/export tool from one wiki to another (I'm
actually trying to export from an online xwiki to a testing instance
locally in my machine), and the resulting file from the export process
turned out to have around 255MB. I have the xwiki enterprise 1.7.1
installed on my machine (including a Jetty container and an HSQLDB
database all set up). When I try to upload the exported file, I get an
error message saying that the max upload size is 10MB. I already changed
the upload_maxsize property in xwiki.preferences to 300MB (the
information in the field was written in Bytes, equivalent to 300MB), but
yet even so, I keep getting the same error message. I think this might
be a HSQLDB handicap. Am I correct? In any case, how can I solve this
issue so I can proceed with this test?!
Thanks a lot !
Roney
