VLAN's in Oracle VM 3.0.1
hi all
i have made a trunk on the cisco switch for my port eth1. i trunk vlan16 and vlan20. when i create this two vlan segments in oracle vm, i have no connect. when i make a untagged vlan than it works with both networks. but i want split it in 2 segments. can oracle vm 3.0.1 work with this function / trunk from a cisco switch? or what must i do that i can define 2 segments over vlan on oracle vm?

Once you enable the VLAN stuff, it'll start tagging the packets with those VLAN IDs. I have several VLANs working in my OVM 3.0.1 install, so I know it works. :)

We recently encountered an issue with our iStore server where the CPU spiked taking the website offline. The server was still up and running however we were forced to restart Apache to get the server back up and running. The logs were very undescriptive outside of the following error: <jservException> Connection from /172.16.1.2 refused due to authentication failure. Everything has worked fine before/since this incident.
We are running iStore/EBS version 11.5.10 and our overall architecture is one iStore server in the DMZ with an application server and a DB server on our server VLAN all running Oracle Enterprise Linux. What steps can we take to track down this issue to find the root cause? Any help would be appreciated, thanks.Sharuk wrote:

Oracle 10g RAC - Private Interconnect on Private non-routable VLAN
In our data center there is an existing Oracle 10g RAC configured with private VLAN for Interconnect administered by a different group of DBAs.
We are designing a new, separate Oracle 10g RAC environment to support our application.
When we discussed with our data center folks to set up a private VLAN for our RAC Interconnect, they suggest to use the same existing Private VLAN used by other Oracle RAC configurations. In that case the Interconnect IPs will be on the same subnet as other Oracle RAC configurations.
For example, if
RAC1 with 2 nodes is using 192.168.1.1 and 192.168.1.2 in the VLAN_1 for the Interconect, they want us to use the same VLAN_1 with Interconnect IPs 192.168.1.3 and 192.168.1.4 for our 2 node RAC.
Is Sharing same subnet on the same Private VLANs for interconnects of different RAC configurations supported?
Will that cause any performance hit? That means the Interconnect IPs of One RAC configuration is pingable from other RAC configuration.
Did anyone come across such a design?
Could not find any info on this on Metalink.
Thanksyes
this is practically very much feasible.. as you would have only 4 m/c in ip subnet .... and this is very much less than the public subnet which we should refrain from using from interconnect. -
Oracle RAC Interconnect, PowerVM VLANs, and the Limit of 20
Hello,
Our company has a requirement to build a multitude of Oracle RAC clusters on AIX using Power VM on 770s and 795 hardware.
We presently have 802.1q trunking configured on our Virtual I/O Servers, and have currently consumed 12 of 20 allowed VLANs for a virtual ethernet adapter. We have read the Oracle RAC FAQ on Oracle Metalink and it seems to otherwise discourage the use of sharing these interconnect VLANs between different clusters. This puts us in a scalability bind; IBM limits VLANs to 20 and Oracle says there is a one-to-one relationship between VLANs and subnets and RAC clusters. We must assume we have a fixed number of network interfaces available and that we absolutely have to leverage virtualized network hardware in order to build these environments. "add more network adapters to VIO" isn't an acceptable solution for us.
Does anyone know if Oracle can afford any flexibility which would allow us to host multiple Oracle RAC interconnects on the same 802.1q trunk VLAN? We will independently guarantee the bandwidth, latency, and redundancy requirements are met for proper Oracle RAC performance, however we don't want a design "flaw" to cause us supportability issues in the future.
We'd like it very much if we could have a bunch of two-node clusters all sharing the same private interconnect. For example:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.16.4 / 255.255.255.0 / VLAN 16
Cluster 2, node 2: 192.168.16.5 / 255.255.255.0 / VLAN 16
Cluster 3, node 1: 192.168.16.6 / 255.255.255.0 / VLAN 16
Cluster 3, node 2: 192.168.16.7 / 255.255.255.0 / VLAN 16
Cluster 4, node 1: 192.168.16.8 / 255.255.255.0 / VLAN 16
Cluster 4, node 2: 192.168.16.9 / 255.255.255.0 / VLAN 16
etc.
Whereas the concern is that Oracle Corp will only support us if we do this:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.17.2 / 255.255.255.0 / VLAN 17
Cluster 2, node 2: 192.168.17.3 / 255.255.255.0 / VLAN 17
Cluster 3, node 1: 192.168.18.2 / 255.255.255.0 / VLAN 18
Cluster 3, node 2: 192.168.18.3 / 255.255.255.0 / VLAN 18
Cluster 4, node 1: 192.168.19.2 / 255.255.255.0 / VLAN 19
Cluster 4, node 2: 192.168.19.3 / 255.255.255.0 / VLAN 19
Which eats one VLAN per RAC cluster.Thank you for your answer!!
I think I roughly understand the argument behind a 2-node RAC and a 3-node or greater RAC. We, unfortunately, were provided with two physical pieces of hardware to virtualize to support production (and two more to support non-production) and as a result we really have no place to host a third RAC node without placing it within the same "failure domain" (I hate that term) as one of the other nodes.
My role is primarily as a system engineer, and, generally speaking, our main goals are eliminating single points of failure. We may be misusing 2-node RACs to eliminate single points of failure since it seems to violate the real intentions behind RAC, which is used more appropriately to scale wide to many nodes. Unfortunately, we've scaled out to only two nodes, and opted to scale these two nodes up, making them huge with many CPUs and lots of memory.
Other options, notably the active-passive failover cluster we have in HACMP or PowerHA on the AIX / IBM Power platform is unattractive as the standby node drives no resources yet must consume CPU and memory resources so that it is prepared for a failover of the primary node. We use HACMP / PowerHA with Oracle and it works nice, however Oracle RAC, even in a two-node configuration, drives load on both nodes unlike with an active-passive clustering technology.
All that aside, I am posing the question to both IBM, our Oracle DBAs (whom will ask Oracle Support). Typically the answers we get vary widely depending on the experience and skill level of the support personnel we get on both the Oracle and IBM sides... so on a suggestion from a colleague (Hi Kevin!) I posted here. I'm concerned that the answer from Oracle Support will unthinkingly be "you can't do that, my script says to tell you the absolute most rigid interpretation of the support document" while all the time the same document talks of the use of NFS and/or iSCSI storage eye roll
We have a massive deployment of Oracle EBS and honestly the interconnect doesn't even touch 100mbit speeds even though the configuration has been checked multiple times by Oracle and IBM and with the knowledge that Oracle EBS is supposed to heavily leverage RAC. I haven't met a single person who doesn't look at our environment and suggest jumbo frames. It's a joke at this point... comments like "OMG YOU DON'T HAVE JUMBO FRAMES" and/or "OMG YOU'RE NOT USING INFINIBAND WHATTA NOOB" are commonplace when new DBAs are hired. I maintain that the utilization numbers don't support this.
I can tell you that we have 8Gb fiber channel storage and 10Gb network connectivity. I would probably assume that there were a bottleneck in the storage infrastructure first. But alas, I digress.
Mainly I'm looking for a real-world answer to this question. Aside from violating every last recommendation and making oracle support folk gently weep at the suggestion, are there any issues with sharing interconnects between RAC environments that will prevent it's functionality and/or reduce it's stability?
We have rapid spanning tree configured, as far as I know, and our network folks have tuned the timers razor thin. We have Nexus 5k and Nexus 7k network infrastructure. The typical issues you'd fine with standard spanning tree really don't affect us because our network people are just that damn good. -
Hello,
I have installed Oracle VM on Dell Poweredge 2950 with broadcom netextrem II chipset NIC. When i configure the vlan with this commands :
vconfig add eth1 201
ifconfig eth1.201 192.168.201.233 up
it's not match. The NIC don't TAG the packets.
If i configure a Red Hat enterprise 5.2 with the same command and port on my switch CISCO, it's OK, the VLAN is correctly TAG.
The drivers in Oracle VM had a problem ?
Thank's for your help.It seems that these drivers are broken:

How to create a multiple VLAN or xenbr in oracle vm
hi,
i have a server which has a 1 nic card.hence having 1 xenbr i.e.xenbr0
now my requriement is to create multiple vlan or xenbr into the system.so instead of 1 xenbr i can have many xenbr's & all my guest vm's are in differernt subnets.
i have trunked the network port from switch side
i refered below url but still not working..
http://wiki.oracle.com/page/Oracle+VM+Server+Configuration-bondedand+trunked+network+interfaces
please help...To create a new brigde and use it in your hosts you can try this
brctl addbr xenbrX
ip link set xenbrX up
brctl addif xenbrX ethY
ifup ethY
you have created a new bridge with the number "X" on interface "Y" ... now all you have to do is configure you guests to use this new configuration:
vif = ['
type=ioemu,
bridge=xenbrX'
Hope this helps! ;)

Oracle VM 3.1.1 and VLAN problem.
Hi There
We got two vlans, 10 and 11. 10 is used for our "Server Management" and 11 is used for "Cluster heartbeat" and "Live Migrate".
So, when I added ovs1(the fist server), it discover the following:
192.168.1.0 - 192.168.1.0-vpg
Then I add the second vlan 11 and my "networks" look like this:
192.168.1.0 - 192.168.1.0-vpg
10.0.0.0 - 10.0.0.0-vpg
Everything is still fine, I added the second server (ovs2) last night to the pool. I did some live migrations and test on the pool.
This morning when I wanted to do a live migration OVMM complained that it is not in the same network group.
So this is what I found under "vlan groups:
192.168.1.0 - 192.168.1.0-vpg
10.0.0.0 - 10.0.0.0-vpg
0004fb00002500005ea963abcbaf0a1d
So it seems that OVMM does not add it to the 192.168.1.0-vpg group ? And when I do a "rediscover" on ovs2, OVMM just create a new random number with that IP in.
Any ideas... Do I need to log an SR ?
Regards
NardusHi There
I don't know if this is the right way but it did solve the issue for me.
I have compared files in the /etc/sysconfig/network-scripts directory and discovered that there was some files missing. The files that you need to look for is meta-bond0 and meta-vlan11. It seems that this files is been created when a server is installed or added to a pool and for some reason the meta-vlan* file is not created. This was on the server that wasn't adding the correct network. I made sure the meta-* files was the same on all my server, this might be different for your setup. After adding the missing meta-* file, I did need to remove the server from the pool and rediscover it.
Hope it helps.

How to configure Solaris 10 IPMP for Oracle VDI 3.3.2
Hi,
Does anyone have an indication on how to configure Solaris 10 IPMP in a manner that supports Oracle VDI?
We have setup two servers with 2 test addresses on physical and 1 logical for the hostname of the box, but when we configure VDI the VDI database does not come up on the 2nd box. We have also tried configuring IPMP without test addresses, but it doesn't make any difference - the DB still doesn't go into the up state after configuration on the 2nd server.
Solaris 10 u9 with patches
Two physical NICs on management VLAN via 2 switches
Two physical NIcs on VDI VLAN via 2 switches
VDI 3.3.2
All hostnames are in DNS and resolve for short name, FQDN and also reverse IP lookup
The is a proposal pdf on Oracle website that mentions IPMP, so someone has done it. Just could do with a hint on how it was done so that it works.
( http://www.oracle.com/us/technologies/virtualization/vdi-design-proposal-1401195.pdf )
Thanks
PaulOK, updating this with what was causing the issue.
Not an IPMP problem this was a DNS problem. The VDI servers have access to two DNS environments, so had a DNS search path that had the domain where the VMs where going to go and another for management of the box with two DNS servers listed in /etc/resolv.conf.
We configured VDI using the FQDN for the management DNS, however the vda-config script takes the hostname of the box adds the first DNS domain from /etc/resolv.conf search entry and configures using (it seams to ignore what you put into the vda-config). When the config script comes to configuring MySQL because the names didn't match (FQDN it created by adding hostname to the 1st entry in DNS search path & FQDN that you put into vda-config command), it decides that it is configuring a "Client MySQL" instance rather than a "Slave MySQL" instance, which means the VDA DB never comes up in the out of vda-center status.
So the fix is to:
1) configure IPMP without test addresses (so traffic comes out of the correct IP and can be reverse looked up in DNS by the other host)
2) if you have multiple DNS search entries, configure VDI using the first entry in your search path as its FQDN

How to configure Oracle VM(Xen) bridge networking?
Hi,
I have installed Oracle VM (Xen) and within it 2 VM Templates: One for Oracle 11g DB and the other with Siebel App. RHEL5.3 x86
The problem is that I cannot get the xen network bridge to work properly and get no ping to the gateway or any other ip from the VM's.
arping to and from the vm's to the hosting xen works ok.
i have configured the vm.cfg to have : vif = ['type=netfront,bridge=xenbr0',] is this correct?
Can you please help?
Thanks,
Liron
On the VM(Siebel App) for example:
/etc/sysconfig/network-scripts/*ifcfg-eth0* seem ok.
I had eth1 in my ifconfig right after I added ['bridge=xenb0'] but somehow I am now getting 'Device not present'
though I am not sure this is the issue.

Show the device that actually bears your IP
[root@bdk-esb-ovs11 ~]# ip route show dev 0a004300
default via 10.0.67.10
10.0.67.0/24 proto kernel scope link src 10.0.67.32
[root@bdk-esb-ovs11 ~]# cat /etc/resolv.conf
nameserver 10.0.67.10
[root@bdk-esb-ovs11 ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=bdk-esb-ovs11
GATEWAY=10.0.67.10
Now correct the GATEWAY:
[root@bdk-esb-ovs11 ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=bdk-esb-ovs11
GATEWAY=10.0.67.1
The network needs restart now, to get the right gateway.
BEWARE , Do get downtime to restart the network on OVS.
Alternatively migrate your machine to another OVS .
# service network restart
My VM on the OVS server survived a service network restart on its host OVS, but missed 18 pings..

Hello,
I am an engineer working with a Cisco Gold Partner in Saudi Arabia. We have a large university as our client where they are constructing a new
building and require our services to build the network infrastructure. Therefore, we are to implement the routing and switching infrastructure as
well as the Wireless solution.
At present, I have no issues in implementing the R&S infrastructure as it is very straight forward but it has implications on the deployment of
the wireless solution which I explain further below. The R&S infrastructure comprises of the typical Core, Distribution, and Access layers and we
are focusing on the local distribution and access switches with regards to the new building. The client has a converged Layer 3 network spanning
from distribution layer to core layer and they are running EIGRP for this convergence. This is not a problem and has already been implemented.
Yet, the challenge arises in deploying the WLAN infrastructure. The client already has a Cisco WLAN infrastructure in place where they have a
large number of LAPs that are registered with their controllers in the Data Center. They have two WLC 5508 where one is the Primary and the other
the Secondary. The local distribution switch to which the WLC are connected also is the gateway for the SVIs for the SSIDs that are configured on
the controllers. This means that once the packets from the AP come in to the WLC, they are tagged with the correct VLAN and sent to the directly
connected distribution switch which then routes it into the rest of the Layer 3 network. Interestingly, the WLC 5508 are running AireOS 7.6 and
support the "New Mobility" feature. The two controllers have formed a Mobility Group (MG) between each other.
Now, the new building will have two Catalyst 3850 switches installed where each one has a total of 40 AP licenses pre-installed and activated
i.e. a total of 80 APs can be supported by the two switches. A total of 67 LAPs will be deployed in the new building which can be accommodated
between the two switches and their integrated controller.
Yet, based on my understanding and research about Converged Access is that, ideally, the Catalyst 3850 will only run the Mobility Agent (MA)
feature while a central controller would provide the Mobility Controller (MC) service. unfortunately, there are not enough licenses on the
existing WLC 5508 nor can we migrate the new licenses that will facilitate such a split deployment.
This means that I would need to configure the two Catalyst 3850 as independent MC and form a MG between them. I have done this and tested this
already and the mobility is working fine. But my concern is not about getting the Catalyst 3850 to work as this is simple but rather it is
focused on creating a common Mobility Domain (MD) so that clients can roam from this new building to the rest of the campus while maintaining the
state of their connections to the WLAN infrastructure.
To make things more complicated, since the new building will have its own Layer 3 distribution switch and the Catalyst 3850 switches will connect
to this distribution switch, it means that new VLANs and SVIs need to be created for the SSIDs broadcast in the new building. This means that new
subnets need to be assigned to the SSIDs.
As such, I have the following questions:
Q1) If we create new SVIs for the SSIDs (same SSIDs names will be used in the new building as in the rest of the university campus) this means
that new subnets will be assigned to these SSIDs. Now, I believe I have two options...one is to make the new Catalyst 3850s to be in the same MG
as the existing WLC 5508 which then cater for Layer 3 client roaming or I have to treat this as a totally seperate WLAN network and follow on to
the solution as per the next question. Please advise which is a better option?
Q2) I could create separate MG i.e. the new building Catalyst 3850s can be in one MG and the existing controllers can be in another MG. I can
then have one of the existing WLC 5508 (the primary one) to run the Mobility Oracle (MO) feature so as to create a single Mobility Domain (MD).
Would this facilitate in Layer 3 client roaming and RRM for all the controllers in the same MD?
Q3) If I do create a MD, how is this accomplished in such an environment since the documentation is severely limited in this regard?
Please advise at your earliest. To assist further, I have attached a topology diagram which may aid in explaining the situation with more
clarity. If these things are clarified, I will be better able to wrap my head around the technology and in turn service my clients better.
Regards,
AmirHi Amir,

I would configure them in the same mobility group. Also configure same SPG for those two 3850 stacks if users are frequently roaming within these two buildings.
Q2) I could create separate MG i.e. the new building Catalyst 3850s can be in one MG and the existing controllers can be in another MG. I can then have one of the existing WLC 5508 (the primary one) to run the Mobility Oracle (MO) feature so as to create a single Mobility Domain (MD). Would this facilitate in Layer 3 client roaming and RRM for all the controllers in the same MD?
MO is not required (it is only for very large scale deployments)
Q3) If I do create a MD, how is this accomplished in such an environment since the documentation is severely limited in this regard?
Yes, documents are hard to find :(
These notes may be useful to you based on my experience. I am running IOS-XE 3.6.1 in my production.

Install Oracle VM Server T4-4 from OPS Center 12c
Hello,
I try to install my new server T4-4 from OPS Center with a New profile OS Provisioning. It start and work perfectelly, but when arrive the time to configure the Network in aggregate (net2 and net3).
the process is never execute. From the cisco switch all is well done for aggregate the port.
I have the following messages just after the first reboot.
Is there a DOC or any idea will be appreciate.
Thank's for help

Here's the VNET config for the other LDOM in the RAC cluster:

Need help with configuring a Printer Driver in Oracle apps
Hi,
We have set of interfaces/concurrent jobs which are programed to send the output file to file location1. Now we need to direct the output for all these jobs to file location2. The idea is to not modify the existing code, but have configuration in place which will re-direct the output files to the new “file location2”, once the concurrent job run is complete.
We have come across “Using Dummy Printer driver” option wherein we created a dummy printer driver with arguments as below and attached this printer to all these concurrent jobs.
mv <file location1>/$PROFILES$.TITLE <file location2>
This option is working fine if both the file locations are hard coded. But both these locations are configured in 2 separate profile options and the filepath would change from once Oracle instance to another.
We are looking for solutions where we can pass the profile option value to this printer driver instead of hardcoding it in the argument.
Also, please suggest any other solution to move the output files to a different location.
Please note that our client is on Oracle On-Demand environment (apps – 11.5.10) and hence a shell script cannot be used for this.
Thanks,
Kiranmayi.Hello Mark,
I can't support the netopia router/modem, but I would think there should be an admin guide for the configuration. If it is a modem/router and you said there is rules for allowing or blocking services, which sounds like access list you should be able to create a rule for the client you want to block on the modem/router to prevent it from talking to the internet.
If you want to insure no outside security threats can make it to the computer staticly assign an IP address but don't give it a default gateway address. The client will not be able to talk to any other network but its own. It sounds like you only have one vlan or a flat network so this should work, but if you need to be able to have this computer in the future talk to other networks internally then it isn't a viable solution. Blocking at the modem/router would be the only solution.
The SG300-08 Switch you could setup an ACL to block that client from talking to the modem/router, but the potential for causing valid traffic from being blocked in your own network grows.
To create this rule you would first
go to Access Control
Create a MAC Base ACL (give it a meaning full name)
Create 2 a MAC BASE ACE
Rule 1
Priority 10
Action Deny
Destination Any
Source User Defined
MAC address of client wanting to be blocked
Apply
Rule 2
Priority 20
Action Permit
Destination Any
Source Any
Apply
Bind the ACL to a port
Make sure to only bind the ACL to the port that connects to the router/modem.

Oracle 11g RAC on HP BladeSystem
We are on our way to evaluate the HP BladeSystem on which we will also deploy RAC.
Regdg. the same we had some queries:
We will have 4 network ports on each DB node. 2 will go for iSCSI and the remianing 2 will be bonded (so it'll appear as 1) and the bonded port alongwith VLANs will be used for public LAN, private LAN as well for other access to the systems. Is this supported i.e. will RAC install happen successfully using virtual interfaces? And is that the correct way to do it?
If not, then what is the alternative? Should we have 2 more ports on each node and also have 2 dedicated switches for the interconnect? Is that what most others who have experience running RAC on blades have done?
Also, it would be helpful if experts or others with a similar experience can help understand how different is it from a non-blade deployment (one diff that we have already understood is that it'll be iSCSI and not FC).
Many thanks.On Hp-Unix, although we have ServiceGuardextension for Oracle RAC (SGeRAC), we will still need to configure Oracle Clusterware (CRS). In this case Oracle Clusterware works along side of SGeRAC.
OCFS2, or Oracle Cluster FileSystem is a storage alternative made available on limited Operating Systems (OEL,RHEL,MS Widows etc).
I think that answers your question. Haig said that, you might want to use Shared raw volumes/devices/partitions in combiation with SGeRAC. We could use HP Cluster File System, but must understand it is not Certified yet.
For database storage, we can use ASM/RawPartitions. I'd recommend a verification with Oracle Certification matrix for such issues.
