On trying to startup the database the following errors occur:
ORA-27500: inter-instance IPC error
ORA-27300: OS system dependent operationort_create failed with status: 134
ORA-27301: OS failure message: Transport is not connected
ORA-27302: failure occurred at: skgxpcini1

N.B. SMMNI = 2000 (Large enogh)

Any Idea??

Thanks In advance
