Обсуждение: PostgreSQL ontop of FreeBSD jails, maybe there is still hope!
It seems there are certain projects running at the moment that will eventually make possible to run PostgreSQL on FreeBSD's jail (virtual server on plain iron speed). Pre jail resource limits: http://freebsdfoundation.blogspot.com/2010/07/resource-containers-project.html Further generalization improvements: http://freebsdfoundation.blogspot.com/2010/06/update-on-jail-based-virtualization.html "Further, the project includes generalization of the virtual network stack framework, factoring out common code. This will provide an infrastructure and will ease virtualization of further subsystems like SYSV/Posix IPC with minimal overhead. All further virtualized subsystems will immediately benefit from shared debugging facilities, an essential feature for earlyadopters of the new technology." By solving the SYSV/IPC problems, PostgreSQL will be able to be run on jails, even easier and more robustly than it is the case now. Lets hope those guys will deliver smth good. -- Achilleas Mantzios

We've been doing that across the project infrastructure for 10 years or more. The only issue we run into is that we need to use a unique port in each jail as shared memory isn't entirely isolated between jails. -- Dave Page EnterpriseDB UK: http://www.enterprisedb.com The Enterprise Postgres Company

Thats a pretty known workaround, still inconvenient and annoying for massive scale virtual environments. > > > -- > Dave Page > EnterpriseDB UK: http://www.enterprisedb.com > The Enterprise Postgres Company > -- Achilleas Mantzios
