Oracle Server Not Starting Local Tetra

1) Stop and start oracle. Ensure that Oracle services are completely stopped before starting.

/etc/init.d/dbora stop

ps -elf | grep ora

pkill -u oracle 

OR

kill -9 <oracle ID>

/etc/init.d/dbora start

2) Check with 'ip a' if two ip addresses are bound to eth1. The two addresses are 192.168.1.37, and 192.168.0.3. If either is not up, make it up and restart oracle.

ip a

Output:

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 100
    link/ether 00:07:e9:09:f9:9c brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.37/24 brd 192.168.1.255 scope global eth1:0
    inet 192.168.0.3/24 brd 192.168.0.255 scope global eth1
    inet6 fe80::207:e9ff:fe09:f99c/64 scope link 
       valid_lft forever preferred_lft forever

If 192.168.1.37 is down, run the following:

ifup eth1

If 192.168.0.3 is down, run the following:

ifup eth1:0

Restart oracle after this. Follow step 1.
