NIC Teaming/Bonding Support by Oracle or NOT

hi:
I have customers using RedHat Linux ES3 Update 6 with NIC Bonding/Teaming on the Oracle 10G RAC's private/heartbeat LAN, I would like to hear from you all or Oracle Support whether SUCH CONFIGURATION IS SUPPORTED BY ORACLE OR NOT.
Thanks.

NIC Teaming/Bonding

Do anyone has a doc or link for NIC teaming/bonding ?
Thanks in advance.

Hi Chandu,
NIC teaming is the process of grouping together several physical NICs into one single logical NIC, it can be used for network fault tolerance and transmit load balance. The process of grouping NICs is called teaming.
It has two purposes:
Fault Tolerance: By teaming more than one physical NIC to a logical NIC, high availability is maximized. Even if one NIC fails, the network connection does not cease and continues to operate on other NICs.
Load Balancing: Balancing the network traffic load on a server can enhance the functionality of the server and the network.
example: http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_example09186a008089a821.shtml
Hope it helps.

NIC teaming/bonding for interconnection

Hi to all,
We are planning for a two node Oracle RAC implementation on Windows Server and we have some doubts about interconnect. Because redundancy is not as important, and because we are limited by money Gigabit switch will be used for interconnection and for public network.
Can we get in bandwidth (load balancing) if we use NIC Bonding on one switch. Which is best?
- To buy servers with two single 1Gb port NIC’s and bond this NIC’s for interconnection and one single port NIC for public network or
- One dual port NIC (bond this NIC’s) for interconnects and one single NIC for public network?

The wrong h/w choices can and will hurt all of these factors.
Can we get in bandwidth (load balancing) if we use NIC Bonding on one switch. No. Bonding usually does not address load balancing. You need to check exactly what the driver stack used for bonding supports.
The primary reason for bonding is redundancy. Not load balancing/load sharing.
Which is best?
- To buy servers with two single 1Gb port NIC’s and bond this NIC’s for interconnection and one single port NIC for public network or
- One dual port NIC (bond this NIC’s) for interconnects and one single NIC for public network?A server with dual 1Gb NICs will be bonded into a single bonded NIC. And that is what then must be used - the logical bonded NIC and not the individual NICs.
This means that 2 1Gb ports provide you with a single bonded port. And you need 2 ports for RAC - public and interconnect.
So you either need 4 physical ports in total to create 2 bonded ports, or 3 ports in total for 1 bonded port and 1 unbonded port.
And what about your cluster's shared storage?
This, together with the Interconnect, determines the robustness and performance of RAC. 1Gb Interconnect is already pretty much a failure in providing a proper Interconnect infrastructure for RAC.
Keep in mind that the Interconnect is used to share memory across cluster nodes (cache fusion). The purpose is to speed up I/O - making it faster for a cluster node to get data blocks from another node's cache instead of having to hit spinning rust to read that data.
Old style fibre channel technology for shared storage is dual 2Gb fibre channels. Which will be faster than your 1Gb Interconnect. How does it make sense to use an Interconnect that is slower (less bandwidth and more latency) than the actual I/O fabric layer?
Would you configure h/w for a Windows server (be that a database, web or mail server) where the logical I/O from the server's memory buffer cache for local disks is slower than actually reading that data off local disk?
Then why do this for RAC?
Last comment - over 90% of the 500 fastest and biggest clusters on this planet run Linux. 1% runs Windows. Windows is usually a poor choice when it comes to clustering. Even Oracle does not provide their Exadata Database Machine product (fastest RAC cluster in the world) on Windows - only on Linux and Solaris (and the latter only because Oracle now owns Solaris too).

NIC Teaming/Bonding with multiple switches.

Today I started setting up in my lab a network with redundant Cisco 2970 switches. The hosts are two HP DL145 servers with two broadcom GBe NICs. The systems are running Linux 2.6.15.1 and I have enabled bonding in the kernel as a module.
Each NIC is plugged into a different switch, and the switches are NOT connected together using ISL or any other method. For all intents they operate as single switches. Each switch is in turn connected to a switch on which my gateway is located.
I have the configuration working using mode 0 (balance-rr). Using tcpdump on the underlying slave interfaces, I can see that packets are in fact being sent out over both interfaces, and that odd sequence numbers are sent on if0 and even numbers are sent on if1. If I unplug one of the interfaces, the bonding driver marks it as down, and stops sending data on that interface. When plugged back in, data transmission is resumed. Furthermore, when using the bonding driver's arp monitoring of the default gateway, unplugging a switch from the upstream switch causes the interface connected to that switch to fail.
My question is if this is a "supported" configuration and/or if there is a better way to make this work.
Furthermore, my next test is to add a PIX 515UR to the mix, and figure out how to connect IT to both switches.
I cannot find any information about how to bond or team interfaces on the PIX, can it do something like this?

NIC teaming in OVM

Hi folks,
Does Oracle VM support NIC Teaming(Bonding of more than 1 NICs in to 1 Logical NIC)? Does it require any driver or patch for the same.
I have SUN server x4710 which has 2 NIC cards.
Moreover If I ve VMs(guests) with IPs of different VLANs(Eg. 10.22.70.x and 202.49.214.x) residing on same VM server what would be the best practice?
Hope fully I have made the points clear..
Thanks in advance...

Moreover If I ve VMs(guests) with IPs of different VLANs(Eg. 10.22.70.x and 202.49.214.x) residing on same VM server what would be the best practice?I usually create a bridge per VLAN. That way, I can create a virtual interface to a guest that is already on a particular VLAN and the guest doesn't have to worry about VLANs. Also, it means you can control VLAN assignments outside the guest OS. See this wiki page for more info:

Hyper-V NIC Team Load Balancing Algorithm: TranportPorts vs Hyper-VPorts

Hi,
I'm going to need to configure a NIC team for the LAN traffic for a Hyper-V 2012 R2 environment. What is the recommended load balancing algorithm?
Some background:
- The NIC team will deal with LAN traffic (NOT iSCSI storage traffic)
- I'll set up a converged network. So there'll be a virtual switch on top of this team, which will have vNICs configured for each cluster, live migration and management
- I'll implement QOS at the virtual switch level (using option -DefaultFlowMinimumBandwidthWeight) and at the vNIC level (using option -MinimumBandwidthWeight)
- The CSV is set up on an Equallogics cluster. I know that this team is for the LAN so it has nothing to do with the SAN, but this reference will become clear in the next paragraph.
Here's where it gets a little confusing. I've checked some of the Equallogics documentation to ensure this environment complies with their requirements as far as storage networking is concerned. However, as part of their presentation the Dell publication
TR1098-4, recommends creating the LAN NIC team with the TrasportPorts Load Balancing Algorithm. However, in some of the Microsoft resources (i.e. http://technet.microsoft.com/en-us/library/dn550728.aspx), the recommended load balancing algorithm is HyperVPorts.
Just to add to the confusion, in this Microsoft TechEd presentation, http://www.youtube.com/watch?v=ed7HThAvp7o, the recommendation (at around minute 8:06) is to use dynamic ports algorithm mode. So obviously there are many ways to do this, but which one is
correct? I spoke with Equallogics support and the rep said that their documentation recommends TransportPorts LB algorithm because that's what they've tested and works. I'm wondering what the response from a Hyper-V expert would be to this question. Anyway,
any input on this last point would be appreciated.

Gleb,
>>See Windows Server 2012 R2 NIC Teaming (LBFO) Deployment and Management for more
info
Thanks for this reference. It seems that I have an older version of this document where there's absolutely
no mention of the dynamic LBA. Hence my confusion when in the Microsoft TechEd presentation the
recommendation was to use Dynamic. I almost implemented this environment with switch dependent and Address Hash Distribution because, based on the older version of the document, this combination offered:
a) Native teaming for maximum performance and switch diversity is not required; or
b) Teaming under the Hyper-V switch when an individual VM needs to be able to transmit at rates in excess of what one team member can deliver
The new version of the document recommends Dynamic over the other two LBA. The analogy that the document
makes of TCP flows with human speech was really helpful for me to understand what this algorithm is doing. For those who will never read the document, I'm referring to this:
"The outbound loads in this mode are dynamically balanced based on the concept of
flowlets. Just as human speech has natural breaks at the ends of words and sentences, TCP flows (TCP communication streams) also have naturally
occurring breaks. The portion of a TCP flow between two such breaks is referred to as a flowlet. When the dynamic mode algorithm detects that a flowlet boundary has been encountered, i.e., a break of sufficient length has occurred in the TCP flow,
the algorithm will opportunistically rebalance the flow to another team member if apropriate. The algorithm may also periodically rebalance flows that do not contain any flowlets if circumstances require it. As a result the affinity
between TCP flow and team member can change at any time as the dynamic balancing algorithm works to balance the workload of the team members. "
Anyway, this post made my week. You sir are deserving of a beer!

NIC Teaming on new 2012R2 install IntelX540-T2 Netgear XS712T not functioning properly

I have a new 2012R2 server with an Intel LOM X540-T2 Dual port, 10-gig copper NIC. I'm trying to team both ports to a Netgear 10-gig copper switch (XS712T, CAT6A cables) and not having much luck. Latest firmware/drivers all around. I reset to factory defaults
on the Netgear switch.
From a console, I go to server manager, NIC Teaming, New Team.
When I try Team Mode: Switch Independent / Load balancing mode: Dynamic. Both ports become Active. I understand that now the adapters listed in networking connections are to be left alone, and that configuration should take place on the Microsoft
Network Adapter Multiplexor Driver. The 'Team' adapter is supposed to DHCP, but never does, and ends up with a private 169.254 address. If I manually configure ip4 on the 'Team' adapter, I still have no communication to the network. Both ports are able
to DHCP when un-teamed. Something interesting is that port 1 only shows received packets, and none sent. At the same time, port 2 shows a much smaller number of sent packets, but zero received. Odd.
When I try Team mode: LACP / Load balancing mode: Dynamic. I add two of the Netgear ports to a LAG and enable LACP. One of the ports in Windows will show 'Active' (and has DHCP'd with normal send/receive), and the other port shows 'Faulted LACP Negotiation'
with very few sent packets and zero received.
Any ideas, or places to look next?
Edit: It looks like I can get physical port 1 to join the LACP group, but physical port 2 will not join, even after swapping cables and rebooting the Netgear switch. But port 1 still goes 'active' regardless of the switchport that it's plugged into.

Oracle can not support upto 32 characters table name and field name ?

hi
oracle up limitation ?

Oracle can not support upto 32 characters table name and field name ?
It is true?
null

Hello All
It's been a year after those posts about the limit of identifiers in Oracle Database. Does anybody know what can be done to get rid of that primitive limit? We are developing using Application Servers, Java, generated Code and a very nice object model, in which we can't just use abreviations because of early database age memory shortcomings.
We are currently using 8i in a very large organization. Is there any chance this version can be configured to allow larger identifiers? Is upgrading to 9i going to solve this problem? Is Oracle Databases really doomed forever because of a 20-year-ago limitation?
Please, I do like Oracle Databases. I don't want to be flooded with quick answers like "just use 32 character identifiers". I would like to hear a serious solution. Is anybody there still locked in the 8.3 filename paradigm of MS/PC-DOS? Does anybody has to fit an entire Enterprise System in segmented 640Kb of memory? Does anybody has to use monochrome character mode interfaces? Of course not those in the mainstream.
I also know that other hadrware and software products have lots os limitations. Take Windows 2000. Its command line has a limit of 255 characters! You can't have more than 4GB of memory in a PC! However, one can't expect one mistake to justify others.
I wish I were very wrong in this respect, and all it should be necessary is to turn on some kind of configuration parameter in 8i to allow us to develop high quality code.
Thanks for your attention.
Please, feel free to contact me if you have a solution.

How to incorporate a Language that is not supported in Oracle Portal

Hi,
I want to know the preferred way to add support for a new language in Oracle Portal.
If a language is not supported in Oracle Portal, how I can add the content for that language in the Portal?
Please advise.
Best Wishes.

I've seen this in a statement of direction presentation as an enhancement for R11. So this should be a R11 feature. In the meantime you might investigate the NLS views and tables and try to find a way to extend this. BUT just in an emergency case and you have to know that is not supported (also you may lose support in general for this installation when hacking the repository). So I cannot recommend this with a clear conscience. You have to know exactly what you're doing.
You can also open a SR to get an official statement from support. Maybe there's a note for this.

FDM is not supported on Oracle RAC? Why not?

[http://download.oracle.com/docs/cd/E12825_01/epm.111/fdm_11113_readme.pdf|http://download.oracle.com/docs/cd/E12825_01/epm.111/fdm_11113_readme.pdf] We are in the process of implementing Oracle Hyperion Financial Data Quality Management (FDM) version 11.1.1.3 as part of our Hyperion Essbase BI environment. I read over the documentation prior to building the databases, but apparently I missed an important bit of information. It seems that FDM is not supported on Oracle RAC. I just noticed this under in the "Known Issues" section of the FDM 11.1.1.3 release notes, and that was only one sentence. The release notes do not explain why this is the case.
- Does anyone know why FDM release 11.1.1.3 is not supported for Oracle RAC?
- Has this always been the case?
- Can a single node database, running on an Oracle 10.2.0.4 two node RAC environment, be used instead of building a separate, stand-alone database?
Link to readme document. The reference to RAC support, or non-support, is on page 6:

"Your browser is not supported by Oracle BI Presentation Services"

Hi,

Can any one tell me the solution for this?
Edited by: Uma on Apr 26, 2012 5:24 AM

Hi Uma,
good that your issue is resolved. we are generally modifying/adding the header to override the existing version to previous version, so instead of using the FF10+ header we are just modifying it to FF9 inorder to make it work
The UA string of Firefox itself is broken down into four components:
Mozilla/5.0 (platform; rv:geckoversion) Gecko/geckotrail Firefox/firefoxversion
Mozilla/5.0 is the general token that says the browser is Mozilla compatible, and is common to almost every browser today.
platform describes the native platform the browser is running on (e.g. Windows, Mac, or Linux). Note that platform can consist of multiple "; "-separated tokens. See below for further details and examples.
rv:geckoversion indicates the release version of Gecko (such as "10.0"). From Firefox 5.0 and Gecko 5.0 onwards, geckoversion is the same as firefoxversion (described below).
Gecko/geckotrail indicates that the browser is based on Gecko. geckotrail is "20100101" in desktop release builds and does not represent the actual build date of the browser. For desktop development builds, geckotrail presently indicates the build date of the browser, but this is likely to change in the future. Starting February 1st 2012, geckotrail is the same as geckoversion and firefoxversion in Firefox for Android with a native front end (aka. Fennec Native).
Firefox/firefoxversion indicates the browser is Firefox, and provides the version (such as "11.0").

Is XMLTYPE not supported in Oracle Lite?

I tried to create a XMLTYPE column in Oracle Lite. I am getting this error.
[POL-5147] this feature is not supported. Is XMLTYPE not supported in oracle lite ?
Can anyone help me understand how to create XMLTYPE column in oracle lite?
Thanks..

Or you could say that they are supported, but sharpening, moire and de-noise are not available (or just set to default), which is actually more Canon's fault. sRAW is a major mess and we're very lucky it's even supported in AP3, finally.

SAP Note 378648 - Offline backup support with Oracle Fail Save

I am trying to implement SAP Note 378648 - Offline backup support with Oracle Fail Save, but am unsure about part of the solution....
Basically, I have to add several parameters into the Environment Variables of the MS Clustered Servers running Windows Server 2003 for the user xidadm...
Fairly straight forward apart from one parameter....
BR_OFS_DOMAIN=<domain>
I am unsure what is required/meant by domain. Can anyone shed some light??

Those are environment variables of the Windows user who is running brbackup; usually this is SAPService<SID>.
You have to set this variables the same way as you set ORACLE_HOME and so on.
(I am not sure about the details; never worked with MS cluster.)
hope this helps
