Last updated on JUNE 07, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 12.2.0.1 and later
Information in this document applies to any platform.

Symptoms

Our database server is configured with 4 private network interface to handle DNFS I/O to NAS storage cluster. The IPs are defined in oranfstab file on the server.

server: vs-nnnnnnnn5000
path: XXX.xx.xx.xxx
local: XXX.xx.xx.xx
path: XXX.xx.xx.xxx
local: XXX.xx.xx.xx
path: XXX.xx.xx.xxx
local: XXX.xx.xx.xx
path: XXX.xx.xx.xxx
local: XXX.xx.xx.xx


However we don't see these paths display in either v$dnfs_channels or in alert.log for 12c databases.

On the same server, the information is available in 11g's v$dnfs_channels and alert.log.
