Hello everyone, no hope to use PostgreSQL + Mosix, because PostgreSQL uses shared memory, as such it's not suitable for migration. Mosix isn't able now to give us a single system image, where a cluster of machine acts as a single transparent machine. I'm trying DIPC+GFS to do this, i've patched the 2.2.17 linux kernel with DIPC , changed PostgreSQL sources to create distributed shared memory and semaphores (postgres uses only sem and shm), next steps are to try to start-up (the changed) postgres to use this distibuted ipc and a central location for datafiles (GFS , NFS?, or a thing that permits a shared fs with flock and fcntl) , then do a simple connect script that , for example , do a round-robin connection to the different postgresql servers on the machineS. DIPC has not a failover mechanism now. Ideas? bye valter >From: Johan Sjöholm <[EMAIL PROTECTED]> >To: "Mosix List" <[EMAIL PROTECTED]> >Subject: PSQL >Date: Wed, 1 Nov 2000 14:09:34 +0100 > >Hello everyone, > >Anyone that has tryied PostgreesSQL under Mosix ?
