Hello-- There must be a better way to do this. I have a class method in my model that finds averages and does a few calculations using find_by_sql. The problem I¹m encountering is that all computed columns from MySQL come back as type string. E.g., def self.find_averages(domain_id) if @@domain_average return @@domain_average else @@domain_average = MyDomain.find_by_sql(["select avg(latency) as latency, avg(datediff(session_end, session_start)) as session_duration from live_logs where domain_id=?"], domain_id])[0] end end The problem is...

The following two patches allow the parallel use of memsharing, xenpaging and xen-access by using an independent ring buffer for each feature.

The following two patches are about how to speed up in xenpaging when page in pages. On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds, but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash. What鈥檚 more,the dom0 is always in high I/O pressure.

...h users. But the problem is that would only allow me to query what users are directly in a given domain. In order to determine what users are in a given domain, you have to include the child domains has well. So what users are in domain MLB? The query would be: SELECT * from domain_users where domain_id IN (1,2,3,4,5) Then for steinbrenner it would be: SELECT * from domain_users where domain_id IN (3) But how do you write a query to know what child, grandchild, etc domains to use? -------------- next part -------------- An HTML attachment was scrubbed...

Address some credit2 issues. This patch series, along with the recent changes to the cpupools interface, should address some of the strange credit2 instability. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

ging_prep ensures that an mfn is backing the paged-out gfn, and transitions to the next state in the paging state machine for this page. Foreign mappings of the gfn will now succeed. This is the key idea, as it allows the pager to now map the gfn and fill in its contents. Unfortunately, it also allows any other foreign mapper to map the gfn and read its contents. This is particularly dangerous
