Public network resources
A Clusterware resource of type ora.network.type is created for each subnet. First, network resource is created
with a cardinality of 1 and named
ora.net1.network
resource. The output of the following crsctl command shows a
resource created for the public network. This network is owned by the root user, with oracrs userid having Read and
Execute permissions.
$ crsctl stat res ora.net1.network -p |more
NAME=ora.net1.network
TYPE=ora.network.type
ACL=owner:root:rwx,pgrp:root:r-x,other::r--,group:oinstall:r-x,user:oracrs:r-x
...
The resource attribute agent_filename indicates that this resource is monitored by orarootagent process. Also,
if there are errors, then the resource is restarted five times before the resource is marked offline.
AGENT_FILENAME=%CRS_HOME%/bin/orarootagent%CRS_EXE_SUFFIX%
...
RESTART_ATTEMPTS=5
SCRIPT_TIMEOUT=60
Interfaces eth1 and eth2 are configured for the public network. Further, this resource captures subnet details of
the public network; thus, all IP public addresses must be in this configured subnet.

USR_ORA_IF=eth1 eth2
USR_ORA_NETMASK=255.255.254.0
USR_ORA_SUBNET=10.11.45.0
VERSION=12.1.0.0.0
Network configuration as discussed so far can also be easily retrieved using the srvctl command. Output of the
srvctl command shows that there is a
net1
network configured in the 10.11.45.0 subnet on the eth1 and eth2 interfaces.
$ srvctl config network
Network exists: 1/10.11.45.0/255.255.254.0/eth1:eth2, type static
