Re: [Virtuoso-users] Migrating from x64 to x86 and back

Thank you Kinsley! I have remounted Amazon EBS to downgraded instance, replaced database files and Virtuoso magically started without any problem. 2010/5/18 Kingsley Idehen > Alexander Sidorov wrote: > >> Hello! >> >> For economical reasons I have to migrate from CentOs x64 (Amazon EC2 >> Large)

Hi Kingsley, Yes, geo capabilities work very well under Virtuoso Cloud Edition (good performance was a great surprise after migrating from lod.openlinksw.com to custom Amazon EC2 instance). Here I will quote the initial question to point out the problem: "Prevously I executed LGD queries using lo

Re: [Virtuoso-users] Clear graph
