Oracle appliance is proposing various possibilities for creating databases either on the Bare Metal or using KVM DB System. Each DB System will host a single database in a separate VM. What about having each DB system running a separate network? In this blog I would like to share my tests and findings about how to create additional network on the ODA and how to create DB System on separate VLAN interface. The principle would be of course the same if we would like to create KVM Virtual Machines (compute instance) on separate VLAN.
Configuration description
For my test I have got an ODA X8-2M with a quad-port 10GBase-T network interface. I’m running ODA version 19.13.
On my network card, the 2 first ports p7p1 and p7p2 will be assigned to btbond1 and the 2 next ports p7p3 and p7p4 will be assigned to my second bonding interface btbond2. ODA are configured by default with active-backup mode without LACP for all bonding interfaces. This is automatically designed by the ODA and can not be changed. More over we need to keep in mind that on an appliance we will never manually change the Linux network scripts. All network configuration changes needs to be done with odacli.
btbond1 is used for my main network and we will use btbond2 to add additionnal networks.
The 2 additional networks are :
10.38.0.1/24 VLAN id 38
10.39.0.1/24 VLAN id 39
Checking network interface
With ethtool I can check and see that the 2 p7p3 and p7p4 ports are twisted pair and connected to the network :
[root@dbi-oda-x8 ~]# ethtool p7p3 | grep -iE "(bportb|detected)" Port: Twisted Pair Link detected: yes [root@dbi-oda-x8 ~]# ethtool p7p4 | grep -iE "(bportb|detected)" Port: Twisted Pair Link detected: yes
I can see that both those interfaces are assigned to btbond2 interface :
[root@dbi-oda-x8 ~]# grep MASTER /etc/sysconfig/network-scripts/ifcfg-p7p3 MASTER=btbond2 [root@dbi-oda-x8 ~]# grep MASTER /etc/sysconfig/network-scripts/ifcfg-p7p4 MASTER=btbond2
Checking existing and default ODA configuration
After reimaging an ODA we would have the below default configuration.

To use a network interface with the VMs, either a DB System or a Compute instance, the network interface needs to be created in the vnetworks.
VLAN Tagged versus Untagged
If a port on a switch is configured as tagged (trunk port in cisco world), the connected equipment (here our ODA) is VLAN aware, and would need to be tagged as well. The port is enabled for VLAN tagging. Purpose is to pass traffic for multiple VLAN’s. The ethernet frame is enclosing an additional VLAN header. The connected equipment will add the VLAN information in the ethernet frame.
If a port is configured as untagged (access port in cisco world), the connected equipment (here our ODA) does not know anything about in which VLAN it is and does not care about it. The switch will manage it on its own. The port does not tag and only accepts a single VLAN. The ethernet frame coming to the connected equipment will not have any VLAN header.
This is explained in the 802.1Q standard.
Most of the time trunk ports will link switches and access ports will link to end devices, albeit we would like to use several VLAN network on the same ODA network interface.
Creating an additional untagged network
Let’s create an additional untagged physical network on the Bare Metal itself. We will create it on btbond2 interface. Untagged means that the ODA will not add VLAN information in the Ethernet frame.
The option -t bond would be the default one and would here not be required.
[root@dbi-oda-x8 ~]# odacli create-network -n btbond2 -p 10.38.0.10 -m untagged1 -s 255.255.255.0 -g 10.38.0.1 -t bond { "jobId" : "9a4476dd-b955-433b-9463-377f66ab737a", "status" : "Created", "message" : null, "reports" : [ ], "createTimestamp" : "February 04, 2022 13:48:12 PM CET", "resourceList" : [ ], "description" : "Rac Network service creation with name untagged1", "updatedTime" : "February 04, 2022 13:48:12 PM CET" } [root@dbi-oda-x8 ~]# odacli describe-job -i 9a4476dd-b955-433b-9463-377f66ab737a Job details ---------------------------------------------------------------- ID: 9a4476dd-b955-433b-9463-377f66ab737a Description: Rac Network service creation with name untagged1 Status: Success Created: February 4, 2022 1:48:12 PM CET Message: Task Name Start Time End Time Status ---------------------------------------- ----------------------------------- ----------------------------------- ---------- Setting network February 4, 2022 1:48:12 PM CET February 4, 2022 1:48:18 PM CET Success Setting up Network February 4, 2022 1:48:12 PM CET February 4, 2022 1:48:12 PM CET Success restart network interface btbond2 February 4, 2022 1:48:12 PM CET February 4, 2022 1:48:18 PM CET Success [root@dbi-oda-x8 ~]# odacli list-networks ID Name NIC Interface Type Subnet Mask Gateway VLAN ID Node Networks -------------------------------------- -------------------- ------------ --------------- ------------------ ------------------ -------- ----------------------- bb05b06c-52eb-41ce-8ed8-92ec712db61d Public-network pubnet BRIDGE 255.255.255.0 10.36.0.1 [IP Address on node0: 10.36.0.241] 95ec74b7-4f6f-4cda-9b0c-5bcac731666b ASM-network privasm BRIDGE 255.255.255.128 [IP Address on node0: 192.168.17.2] e77a33d0-2b40-4562-b802-c02cadd93b25 Private-network priv0 INTERNAL 255.255.255.240 [IP Address on node0: 192.168.16.24] 6171aad7-e247-4b08-a56e-83bdedd74af1 untagged1 btbond2 BOND 255.255.255.0 10.38.0.1 [IP Address on node0: 10.38.0.10] [root@dbi-oda-x8 ~]# odacli list-vnetworks Name Type Interface Bridge Uniform Created Updated -------------------- --------------- --------------- -------------------- -------- ----------------------- ----------------------- pubnet Bridged btbond1 pubnet NO 2022-01-28 08:54:55 CET 2022-01-28 08:54:55 CET
I can see that our new network exists in the network list but not in the virtual network of course.
I can also check and see that our btbond2 interface has been configured by odacli as an untagged bonding interface with the appropriate information.
[root@dbi-oda-x8 ~]# ip addr sh btbond2 9: btbond2: mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 3c:fd:fe:92:80:1a brd ff:ff:ff:ff:ff:ff inet 10.38.0.10/24 brd 10.38.0.255 scope global btbond2 valid_lft forever preferred_lft forever [root@dbi-oda-x8 ~]# ls -ltrh /etc/sysconfig/network-scripts/ifcfg*btbond2* -rw-r--r--. 1 root root 262 Feb 4 13:48 /etc/sysconfig/network-scripts/ifcfg-btbond2 [root@dbi-oda-x8 ~]# cat /etc/sysconfig/network-scripts/ifcfg-btbond2 #This file was created by ODA.

Of course it is not possible to create another untagged network on btbond2 interface knowing there is already one existing :
[root@dbi-oda-x8 ~]# odacli create-network -n btbond2 -p 10.39.0.10 -m untagged2 -s 255.255.255.0 -g 10.39.0.1 -t bond DCS-10001:Internal error encountered: nicnamebtbond2 already exists in the networks list .. .
Creating an additional tagged network would also not be possible. Note the option -t and -v to create tagged networks on the ODA :
[root@dbi-oda-x8 ~]# odacli create-network -n btbond2 -p 10.39.0.10 -m tagged2 -s 255.255.255.0 -g 10.39.0.1 -t VLAN -v 39 DCS-10001:Internal error encountered: Creating vlan in the interface btbond2 is not allowed. Physical network untagged1 already exists in interface btbond2.
Let’s delete our additional untagged network
[root@dbi-oda-x8 ~]# odacli delete-network -m untagged1 { "jobId" : "3d7a033f-fd9c-4632-a6f1-b80f7d3fcf57", "status" : "Running", "message" : null, "reports" : [ { "taskId" : "TaskSequential_10041", "taskName" : "deleting network", "taskResult" : "", "startTime" : "February 04, 2022 14:08:32 PM CET", "endTime" : "February 04, 2022 14:08:32 PM CET", "status" : "Running", "taskDescription" : null, "parentTaskId" : "TaskSequential_10039", "jobId" : "3d7a033f-fd9c-4632-a6f1-b80f7d3fcf57", "tags" : [ ], "reportLevel" : "Info", "updatedTime" : "February 04, 2022 14:08:32 PM CET" }, { "taskId" : "TaskZJsonRpcExt_10045", "taskName" : "Setting up Network", "taskResult" : "Network setup success", "startTime" : "February 04, 2022 14:08:32 PM CET", "endTime" : "February 04, 2022 14:08:32 PM CET", "status" : "Success", "taskDescription" : null, "parentTaskId" : "TaskSequential_10041", "jobId" : "3d7a033f-fd9c-4632-a6f1-b80f7d3fcf57", "tags" : [ ], "reportLevel" : "Info", "updatedTime" : "February 04, 2022 14:08:32 PM CET" }, { "taskId" : "TaskZJsonRpcExt_10048", "taskName" : "restart network interface btbond2", "taskResult" : "", "startTime" : "February 04, 2022 14:08:32 PM CET", "endTime" : "February 04, 2022 14:08:32 PM CET", "status" : "Running", "taskDescription" : null, "parentTaskId" : "TaskSequential_10047", "jobId" : "3d7a033f-fd9c-4632-a6f1-b80f7d3fcf57", "tags" : [ ], "reportLevel" : "Info", "updatedTime" : "February 04, 2022 14:08:32 PM CET" } ], "createTimestamp" : "February 04, 2022 14:08:32 PM CET", "resourceList" : [ { "resourceId" : "6171aad7-e247-4b08-a56e-83bdedd74af1", "resourceType" : null, "resourceNewType" : "Network", "jobId" : "3d7a033f-fd9c-4632-a6f1-b80f7d3fcf57", "updatedTime" : null } ], "description" : "Network service deleteRacNetwork with id 6171aad7-e247-4b08-a56e-83bdedd74af1", "updatedTime" : "February 04, 2022 14:08:32 PM CET" } [root@dbi-oda-x8 ~]# odacli describe-job -i 3d7a033f-fd9c-4632-a6f1-b80f7d3fcf57 Job details ---------------------------------------------------------------- ID: 3d7a033f-fd9c-4632-a6f1-b80f7d3fcf57 Description: Network service deleteRacNetwork with id 6171aad7-e247-4b08-a56e-83bdedd74af1 Status: Success Created: February 4, 2022 2:08:32 PM CET Message: Task Name Start Time End Time Status ---------------------------------------- ----------------------------------- ----------------------------------- ---------- deleting network February 4, 2022 2:08:32 PM CET February 4, 2022 2:08:34 PM CET Success Setting up Network February 4, 2022 2:08:32 PM CET February 4, 2022 2:08:32 PM CET Success restart network interface btbond2 February 4, 2022 2:08:32 PM CET February 4, 2022 2:08:34 PM CET Success

Creating additional tagged network
Let’s create the first tagged network on btbond2 interface :

And we can see that respective tagged network interface has now been created on the Linux operating system side (note the <btbond>.<vlan_id>) :

Creating virtual networks
Knowing I need to use the networks for the next DB Systems I have deleted the created physical networks and I’m going to create the 2 same tagged networks as virtual networks on the btbond2 interface :

My 2 new tagged networks exists as virtual network and not physical networks :

Tagged network interfaces have been created by the dcs-agent on the linux operating side :
[root@dbi-oda-x8 ~]# ls -ltrh /etc/sysconfig/network-scripts/ifcfg*btbond2* -rw-r--r--. 1 root root 239 Feb 4 14:38 /etc/sysconfig/network-scripts/ifcfg-btbond2 -rw-r--r-- 1 root root 145 Feb 4 15:19 /etc/sysconfig/network-scripts/ifcfg-btbond2.38 -rw-r--r-- 1 root root 145 Feb 4 15:19 /etc/sysconfig/network-scripts/ifcfg-btbond2.39 [root@dbi-oda-x8 ~]# cat /etc/sysconfig/network-scripts/ifcfg-btbond2.38 #This file was created by ODA. Do not edit. DEVICE=btbond2.38 ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=none VLAN=yes ONPARENT=yes BRIDGE=brtagged38 [root@dbi-oda-x8 ~]# cat /etc/sysconfig/network-scripts/ifcfg-btbond2.39 #This file was created by ODA. Do not edit. DEVICE=btbond2.39 ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=none VLAN=yes ONPARENT=yes BRIDGE=brtagged39
On the linux side, I can see that the respective IP addresses have not been assigned to the physical interfaces :
[root@dbi-oda-x8 ~]# ip addr sh | grep -iE "(btbond2|btbond2.38|btbond2.39)" 4: p7p3: mtu 1500 qdisc mq master btbond2 state UP group default qlen 1000 5: p7p4: mtu 1500 qdisc mq master btbond2 state UP group default qlen 1000 9: btbond2: mtu 1500 qdisc noqueue state UP group default qlen 1000 60: btbond2.38@btbond2: mtu 1500 qdisc noqueue master brtagged38 state UP group default qlen 1000 62: btbond2.39@btbond2: mtu 1500 qdisc noqueue master brtagged39 state UP group default qlen 1000
But on new virtual interfaces linked to the tagged btbond2 interfaces :
[root@dbi-oda-x8 ~]# ip addr sh | grep -iE "(tagged38|tagged39)" 59: brtagged38: mtu 1500 qdisc noqueue state UP group default qlen 1000 inet 10.38.0.10/24 brd 10.38.0.255 scope global brtagged38 60: btbond2.38@btbond2: mtu 1500 qdisc noqueue master brtagged38 state UP group default qlen 1000 61: brtagged39: mtu 1500 qdisc noqueue state UP group default qlen 1000 inet 10.39.0.10/24 brd 10.39.0.255 scope global brtagged39 62: btbond2.39@btbond2: mtu 1500 qdisc noqueue master brtagged39 state UP group default qlen 1000
And I can ping them :

I can see the network bridge information from the operating system as well :

Creating 2 DB Systems using respectively tagged38 and tagged39 virtual networks
My repository has already been updated with the KVM DB System Image :

I have created the first DB System json file assigning a new IP address from the VLAN38 network using tagged38 virtual network. The IP connection will use bridging through the virtual VLAN38 IP address we created on the Bare Metal itself :
[root@dbi-oda-x8 ~]# cat /opt/dbi/create_dbsystem_srvdb38.json ... ... ...

I have then created the second DB System json file assigning a new IP address from the VLAN39 network using tagged39 virtual network. That time the IP connection will use bridging through the virtual VLAN39 IP address we created on the Bare Metal itself :

Direct connection on the DB Systems
Finally I can access directly the DB Systems through SSH from my laptop. Here as example, connection to the srvdb38 DB System.

And directly from my laptop I can connect and use the Oracle database DB38 :
Creating a virtual network without assigning an IP address to the bridge interface
Of course it is possible to create a virtual bridge interface without assigning any IP address.
I deleted tagged39 virtual network in order to create it again without IP address :

Of course I could have updated the vnetwork interface using odacli modify-vnetwork and assigning 0.0.0.0 as IP address.
I created again the tagged39 virtual network without assigning an IP address to the bridge interface.

maw@DBI-LT-MAW2 ~ % ssh [email protected] [email protected]'s password: Last login: Thu Feb 17 18:10:10 2022 from gateway [root@srvdb39 ~]# ip addr sh ens3 2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 52:54:00:86:87:88 brd ff:ff:ff:ff:ff:ff inet 10.39.0.20/24 brd 10.39.0.255 scope global noprefixroute ens3 valid_lft forever preferred_lft forever [root@srvdb39 ~]# ps -ef | grep [p]mon oracle 93401 1 0 17:35 ? 00:00:00 ora_pmon_DB39 [root@srvdb39 ~]#
And I can join the DB39 database from my laptop directly :
Conclusion
KVM DB System main purpose is hard partitioning for oracle licensing. All ODA’s cpu cores can remain active. DB System with appropriate pinned CPU core related to the number of licenses will be created for the oracle database. The others ODA’s CPU core can be used for further KVM or application needs.
As we could see KVM DB System will then have an additional pros. With DB System we can separate Database traffic through separated VLANs.
On the other hand KVM DB System will have some other cons :
- More complex installation.
- More resources will be consumed : each DB Systems will run its own oracle restart (grid) infrastructure.
- Each DB Systems will have to be patched separately as well during ODA patching, making patching process more heavy.
Also please note that current ODA release 19.13 supports only creation of database in version 19.11, 19.12, 19.13, 21.3 and 21.4 for the DB Systems.

13.06.2024Hello, once vnetwork are created for tagget vlan, type bridged-vlan, and dbsystems created on it , we would like to view these same vlan as network (odacli list-networks) for baremetal database creation on it via tooling. Seems not possible ? like it is for non-tagged pubnet seen as "bridge" on both sides ? technically as the bridge for tagged vlan can be itself assigned an ip, it is possible to add a database listener on it, but it is manual, outside tooling...

24.06.2024Hi Paul,
Sorry for delay in my answer. You are right, creating vnetwork will not be listed in as network, and you can see this in my blog as well. It is different for the oda public interface (pubnet) that you will see in vnetwork list and network list. On the other hand the network you created as vnetwork is in any case also accessible from the bare metal if you assigned an IP address to your vnetwork. So you could create an additional listener on those ip address. Need to be tested on lab, I do not see any reason why it should not work. Please read my other article, https://www.dbi-services.com/blog/separating-database-traffic-on-an-oda/, where I explained all this. Of course creating this additional listener in the grid infra is manual. There is, so far, no odacli command which will do it for you.
Good luck.
Regards,
Marc
