I use Opensips with NDBCLUSTER, although not with db_virtual. Seems to work okay with db_mysql. To keep things simple, each of my Opensips machines (VMs, really) has a mysqld instance whose only role is to be a front-end to the cluster. I've tried it with CentOS RPMs, Debian (stable) packages, and 7.1.x source from the MySQL site. All okay.
Sorry, no further information on the virtual portion. - Jeff On 12/14/10 12:35 PM, "osiris123d" <duane.lar...@gmail.com> wrote: > >I am trying to get OpenSIPS Virtual_DB module to work with a MySQL Cluster >that I have set up. > >Instead of the database tables being the usual MyISAM I set them up to be >NDBCLUSTER. > >Within the OpenSIPS config I have > ># ----- db_virtual params ----- >modparam("db_virtual", "db_urls", "define set1 ROUND") >modparam("db_virtual", "db_urls", >"mysql://********:***...@173.***.***.219/opensips") >modparam("db_virtual", "db_urls", >"mysql://********:***...@173.***.***.218/opensips") > > >To test I shut down the database on the 173.***.***.218 server and >OpenSIPS >went down.
