Hi everybody! I tried to install the new version of PostgreSQL an everything worked really fine until I typed in the "postmaster -i" command for the first time. The following error message occured: IpcMemoryCreate: shmget failed (Invalid argument) key=5432001, size=1073152, permission=600 FATAL 1: ShmemCreate: cannot create region I am running a Redhat Linux 5.2 on a sparc machine. Does anybody know a solution for this problem? -- Best Regards, Steffen Zimmert Steffen Zimmert Fraunhofer Center for Research in Computer Graphics Providence, Rhode Island, USA email: [EMAIL PROTECTED]
