Re: [Dspace-tech] help! migration causes slow loading of files
i also tried to access - https://dizzyg.library.vcu.edu/browse-title; is dead slow..

Hi Vishal, We don't necessarily need to use https: for everything - it was easier to set up with mod_jk Has anyone set their instance up with http and then used https only for authentication?

Re: [Dspace-tech] help! migration causes slow loading of files
Hi Susan,
We don't necessarily need to use https: for everything - it was easier
to set up with mod_jk
Has anyone set their instance up with http and then used https only
for
authentication?
You can achieve this using mod_rewrite, using rules such as:
## SSL Virtual Host Context
VirtualHost 1.2.3.4:443
...
RewriteEngine on
RewriteCond %{REQUEST_URI}!^/password-login.*
RewriteRule ^/(.*)
http://%{HTTP_HOST}/$1 [L,R]
/VirtualHost
## Non-secure Virtual Host Context
VirtualHost 1.2.3.4:80
...
RewriteEngine on
RewriteCond %{REQUEST_URI}^/password-login.*
RewriteRule ^/(.*)
https://%{HTTP_HOST}:443/$1 [L,R]
/VirtualHost
I hope that helps,

Re: [Dspace-tech] help! migration causes slow loading of files
Hi all, Well, my problem is bigger than expected as the files aren't loading quickly on either production or test. Although we're still checking out university networking issues, I'm still curious to see if anyone has had trouble opening larger files through the Dspace app. For example, here's a couple of larger files (although they're still on ~24 mb) on our production instance: https://dizzyg.library.vcu.edu/bitstream/10156/2476/1/TESI%20VALE.pdf These files never open, but rather just spin. I get no indication in any of the logs that there is an issue. We're using tomcat/apache jk connector, running dspace 1.4.1 on linux thank you!!

Re: [Dspace-tech] help! migration causes slow loading of files
hi Claudia, It does have the proper rights - checked that yesterday eve. My dspace.cfg points there At this point, we think we may have a network issue, but we're still looking into that. thanks so much for your help and let me know if you have other ideas about what it could be. Like I said, we've moved to a much larger server and I thought that would increase the load time of the files. I've also increased the JAVA_OPTS memory to a gig... thanks!

Hi Susan, Assuming you click on a link to the pdf file in a record, what is the resulting URL? Does the new server replace the old server on the same ip-address and host name? Does the URL include a host name you expect? If it is a file system issue, you may want to find the tool to dump it's configured and running characteristics and confirm the combination is all OK. Try adding a pdf file directly to the file system to see if it will write as expected. Also check the logs for the stack of components (e.g. tomcat) and that the account permissions for the application and files are OK. You may also be able to use the mapping of the pdf file name to the assetstore's object path from details in the database and possibly look directly at that object on the file system to see if it is really there and available.
