Hello,
We have a question about 19C grid install :
How can we install "grid infrastructure for a cluster" on a single redhat8 instance/node/server (without RAC architecture) ?
The aim is to use acfs on our databases server for datafiles and reco, which is not possible with oracle restart only.
We know this kind of configuration is possible, as such configuration is set up on a oracle appliance ODA S or M model.
At the grid install step, we are blocked when gridSetup is requesting the differents networks informations.
Here our network configuration :
cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.2.22 redhat1
10.0.2.23 redhat1-scan
10.0.2.24 redhat1-vip
redhat1 is the hostname, with correct ip.
redhat1-scan and vip have fake ip (unreachables) , added in /etc/hosts only to pass the gridSetup.sh step.
As on a ODA, we have on our single redhat node one physical network interface. To answer to the gridSetup requirement, we tried to add 2 additionnal bridged networks priv0 and privasm :
ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 08:00:27:01:7d:20 brd ff:ff:ff:ff:ff:ff

3: priv0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether 4a:3a:1c:02:14:87 brd ff:ff:ff:ff:ff:ff
inet 192.168.16.24/28 brd 192.168.16.31 scope global noprefixroute priv0
valid_lft forever preferred_lft forever
4: privasm: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether fe:33:98:1c:90:3b brd ff:ff:ff:ff:ff:ff
inet 192.168.17.2/25 brd 192.168.17.127 scope global noprefixroute privasm
valid_lft forever preferred_lft forever
In the gridSetup.sh, we used :
2: enp0s3 for the public network interface
3: priv0 ("fake" bridge interface) for private network
4: privasm ("fake" bridge interface) for ASM & private network
The orainstRoot.sh step failed with following error :
[main] [USMInstance.configureLocalASM:3413] ORA-39511: Start of CRS resource for instance '215' failed with error:[CRS-2672]: Attempting to start 'ora.interconnect.haip' on 'redhat1'
In our context, could you please guide us to setup the differents linux network interfaces so the grid infrastructure in cluster mode can successfully complete in a single server ?
Is this kind of installation "grid RAC without cluster" documented and certified by oracle ?
We ask because it's the way it's working on appliances ODA (S and M models). We didn't find any documentation about that.
Again, the aim is to install grid "in cluster mode' to use acfs filesystem for datafiles, redologs and so on ... as Oracle Restart does not support Oracle ACFS
resources on linux platform
Thank you for your help.
