Re: [Dspace-tech] How to purge/remove old thumbnails?
Hi Alcides, you could do something like the following SQL query. Please note that I didn't actually test it, it's just to give you the idea.

Re: [Dspace-tech] High CPU usage
Hi Elvi, I can't tell you why your Tomcat is using 100% CPU, but I'm fairly sure that NullPointerException is not directly related to that. To find out the problem, you should use a Java profiler and find which function Tomcat spends most time in. One other potential source of this could be that you gave Tomcat too little memory and it spends a lot of time doing garbage collection. For other tips, also try a google search for "tomcat 100% cpu".

Hi Ryan, I don't think you can run the DSpace application itself in a clustered configuration (homogenous clusters). That, however, doesn't mean that DSpace can't benefit from a multi-node configuration. There are several parts that can be moved onto separate nodes: 1) the database server (that might in turn be clustered, but that will most likely *not* speed things up) 2) Solr server (may be also clustered, this might provide the most benefit from clustering). Do separate the statistics core (which is write-heavy) from the search and oai cores; or use ElasticSearch-based statistics instead. 3) a frontend HTTP server to serve static resources (especially bistreams) 4) use a separate syslog server to store logs As always, measure the performance benefits of each individual change you make. If you need additional details or if you're not sure what the benefits of each point are, feel free to ask.

Re: [Dspace-tech] LDAP auto-registration -- what am I missing?

Hi Andrew, yes, that sounds like a permissions "problem" on the side of your LDAP server. I'd say that once your user successfully authenticates, he's not allowed to read his own attributes (name, surname, ...) and thus DSpace stores null. Do try to log in using some LDAP client (e.g. ldapsearch or a GUI client like Apache Directory Studio) using the same user's credentials and see if you can read the values of his attributes. > I'm not doing heirarchical authentication, should I be? If you can verify that the problem is what I say it is, you can fix it on the LDAP server side by giving all users permission to read their attributes (at least those that DSpace needs). While you could have one special LDAP account that has read permissions to all the other accounts and use it to retrieve the attribute values, this is not how the code in DSpace currently works. Even if you enable hierarchical auth (which you otherwise don't need - because the authentication itself works for you), DSpace will still use the actual user's account to retrieve its attributes, not the search.user account.

Re: [Dspace-tech] Question about mod_jk, x-forwarded-for and IP-based authentication
Hi Elvi, you're right that you need to configure your Apache to send the X-Forwarded-For headers. Assuming that works on the Apache side, there is one more modification you need to make on the DSpace side to make DSpace look at the IP address in X-Forwarded-For rather than the actual IP address (which in your case is always Apache's IP). You need to set this in dspace.cfg: useProxies = true That should make not only IPAuthentication recognize the IP from X-Forwarded-For, but also other parts of DSpace such as statistics.
