Single NIC card and RAC ???

Hello all,
i 'am tryin to setup a rac with CENTOS 4.4 and open filer for testing purposes
i am following the doc http://www.oracle.com/technology/pub/articles/hunter_rac10gr2_iscsi.html
I have three cpu's each with ONE n/w card. Will it be possible to install oracle clusterware ?
I tried installing oracle clusterware by creating an ifcfg-eth1 file under /etc/sysconfig/network-scripts/ . But it was not detected as a private interface.
Is there any way to proceed with a single NIC card.

You may be able to make the NIC the private interconect, and use the VIP as the public. Not sure if that will work ... it would be tricky, and not recommended due to the amount of traffic on the NIC.
Is there some reason you can't add some cheap 10/100 NIC for the public I/F - PCI, wireless, virtually anything will do. Cards go for $10-$15, assuming you have the space.

Leopard server 10.5.6 with two nic card and two hostname

Hi,
Here is what I am intending to do but don't know how:
-setup a Mac server that has 2 built-in nic.
-nic1 is setup as a DHCP, has proper hostname, DNS, etc. and connects to internet and is easy when you configure it as a server while is connected.
-But, my other nic2 is not DHCP and is cut off from outside and is intended for internal research, but given a proper IP and hostname.
If I want to install the server, then without internet connection it is hard to complete the setup and If I do then it assigns the hostname pointing to the nic1 (which i don't want)
How should I go about this? I tried both way, but Mac picks the hostname that is associated with nic1 always.
Any help is appreciated!
Thanks

Can you do what you want? Sure. (If I understand what you're up to.) But it gets a little ugly.
It's easier to use a firewall-router-NAT device here.
Dual-NIC configurations and IP are an interesting case.
A firewall-router-NAT configuration and the resulting IP routing works out of the box. It also avoids the case where users and software are active on the firewall (as is the case with a dual-NIC host system acting as a firewall), and where these activities happen to modify the firewall configuration; this whether by accident, by intention, or through an exploit. Firewalls are best kept locked down.
If you want to learn IP routing and preferred paths and other network-level considerations, then by all means do continue to work with a dual-NIC host system. (This isn't specific to Mac, either. This is simply how IP and IP routing works. There's no concept of automatically returning the packets of a connection out the same controller that the connection arrived on, for instance. And various IP protocols don't use connections.)
As for DNS and particularly with NAT, you'll probably end up with a split configuration. I'd tend to have an external DNS provider translate the public DNS domain and the public address, and have the NAT box (with port forwarding) map that to the appropriate private IP address. Within the private address space, a private DNS domain (a subdomain of a public registered domain, or a separate registered domain) uses the local (private) DNS server to resolve its queries, and that DNS server forwards queries for which it is not authoritative to the organization's public DNS server.
Do use node.foo.example.com and node.example.com (where you own example.com) or use node.example.com and node.example.net (where you hold both domains), with the former being external and the latter being the internal address space. Having the same name resolve to two different IP addresses gets weird, as (for instance) a laptop moving between domains (particularly in the co-presence of that abomination known as NAT) may not end up routing its IP traffic where you expect. Having the convention of a specific internal subdomain or a specific internal domain also makes the "inside versus outside" distinction very clear, too. It's possible to use a completely private domain internally, but (given ICANN is opening up TLDs, and in the absence of an ICANN-reserved internal-only domain) I don't recommend that.
If you want to continue with the original course of action, this IP routing and split DNS is a common question. Dig around in the forums, and dig around specifically for discussions of IP default routing, for split-brain or split-horizon or split-zone DNS, consider acquiring Cricket Liu's DNS book (which is what we all usually go read when we hit a DNS weirdness), and for tools such as the CutEdge Systems DNS Enabler tool.

RAC with 1 NIC card

Hi Experts
I am trying to configure RAC on 2 desktops and common storage, where the desktops have single NIC cards only. Could you please help me in the steps required to configure the PRIV NIC (aliasing of the NIC).

How to set up set which NIC card to use for multicast?..

 I just downloaded Rolling Patch 1 for WLS6.0SP2.
 While reading the README file it says
 " ISSUE 42518: Provided a way to set which NIC card to use for multicast traffic
 Can anyone tell me how to set this?. on my WebApplication server it has two NIC
 cards and I want to use the NICcard which is being used to talk to internal network
 for multicast messages.
 One more thing,
 Can anyone one tell how to search for bugs (ISSUES) in weblogic. I am looking
 place where I enter ISSUE number and should get the detailed description of bug/issue
 etc..
 Thanks for helping,

 Thanks Kumar, I'll try this.
 Does this -Dweblogic.interfaceAddress used only for multicast. Or this is also
 used to talk to AdminServer?.
 The other problem I am facing is when I restart the AdminServer in recovery mode
 it's not finding my WebApp servers, because my webapp servers are on public network
 and my admin (management) server is on private network.
 please look at http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.developer.interest.management&item=1217&utag=

Connecting two AR5000 receivers on same sound card and stream over net

Hi guys,
I am able to connect one AR 5000 receiver to a sound card , remote control it over the network, stream audio and play from it.
Now I want to connect two receivers on a single sound card and do the rest as mentioned above
Help!!

Thanks Linc Davis. I thought I'd have to pay for the consultation at the Genius Bar, but you're quite right, it is free and you can decide not to go ahead if the quote they give is too much. Just thought I'd write what happened in case anyone else has the same problem. The cause was basically a small cable that needed to be repaired, which cost about 76 euros. I took it to an Apple Store in Paris and they fixed it within 24 hours, even though they estimated 3-5 days. He said another reason this problem might be occurring is because the Logic Board needs to be replaced which would have cost around 360 euros (probably not worth the money for a 3.5 year old laptop), but thankfully it was just the cable.

Install a nic card? and a sound card?

I am a pc user and have recently aquired a power mac g4. It seems the network card and audio card (onboard) are both not working. I know you can install pci cards to pcs for such purposes, but I do not know about macs. So I want to know if it is possible to install these cards, if so how do you install these cards in the mac.
I know with Win XP when new hardware is installed it finds it immediately and you either install the driver or it does it for you. How do you add hardware in a mac? Any help is appreciated because before I buy a new mac I want to learn how to use this one. Thank you!!

Hi,
Too bad about your sound and onboard Nic. Can I ask how you know they are both bad? Seems like a lot to be wrong with a single mac, they are part of the motherboard and difficult to break.
Anyway, you can use a NIC card like this:
http://eshop.macsales.com/item/Sonnet%20Technology/GE1000/
You can plug this into a USB port and then plug speakers into it.

How do I set Link Speed and Duplex Mode of NIC Card

Hi All.
I

I'm working on the tester to verify the various speed at UUT by sending command on those speed and check response.
I used to try Devcon but only disable and enable NIC Card that I know for now. If someone experience on this thing, that would be great.

Migrating single instance SAP and Oracle 11.2.0.1 database to Oracle RAC

We have a single instance SAP Netweaver environment on Oracle 11.2.0.1 database and want to migrate to Oracle 11.2.0.1 RAC and ASM. The documents are for 11.2.0.2 and later but we want a way to:
1. Migrate single instance SAP and Oracle 11.2.0.1 instance to ASM
2. Configure the environment as four node Oracle 11.2.0.1 cluster
Thus far, I have:
1. Installed clusterware 11.2.0.1
2. Installed four ASM instances
My questions:
1. We want to migrate the single instance database to same server and extend to four node cluster and ASM
However, current SID for SAP and Oracle must remain the same. The problem I have is that the target database name needs to be same as source on same physical host.
2. How would I use RMAN to migrate the single instance database to ASM for 11.2.0.1?
3. How would I use rconfig after this step?

3- We have installed four node Oracle 11.2.0.1 clusterware on the above nodesAnd what is the shared storage? For RAC, all shared storage devices for the cluster need to be available and usable by all ASM instances in that cluster.
Issue- we have RAC 11.2 clusterware listener using SCAN and listeners for all four clusterware nodes.
When we try to run the following RMAN command to migrate the single instance Oracle 11.2.0.1 datafiles it fails:The failure says: "+RMAN-10038: database session for channel ORA_DISK_1 terminated unexpectedly+". And this in itself does not tell you what the actual problem encountered is.
4- How to register the single instance with all four ASM instances and network services to resolve the above issue?Register what instance? ASM does not need databases or instances to be registered. It is a storage management layer. The cluster (grid infrastructure) layer is the one that deals with the registration (and management) of the various services and resources on that grid (e.g. ASM instances, database instances, SCAN and VIP, Listener services, etc).
5- Do we need to first run rconfig utility against single Oracle 11.2.0.1 instance to register with clusterware services BEFORE using RMAN to perform the datafile migration to ASM?Never used rconfig. See Support Note +RCONFIG : Frequently Asked Questions [ID 387046.1]+ for details.

ACS SE and NIC Cards

After reading the documentation regarding the NIC cards on the ACS appliance it seems the both cant be used together. Can one be used as a management Interface like on CS-MARS and IPS? while the other performs its normal operation?

unfortunately no, you can only use one NIC that too bottom NIC (NIC 1).
If you want such a feature, you may want to contact your AM, and go for a feature request on this product.

Z87 XPower Board and multiple Single video cards?

I'm lost and can't find an answer anywhere. I use 3 video cards to connect to 6 monitors but for some reason this mobo won't recognize any of my other cards except for the one in PCI_2 since that's wired to the CPU directly... I need to get the other ones working too how can I do this? I checked the CeaseFire switch and they're all set to "On" so they should be working, but alas they are not. Hopefully someone can help me figure out what I am doing wrong.
BTW, these are standalone cards, not crossfire or sli capable.

Quote from: XFM on 29-June-13, 10:27:36
Not that it make much difference to any of us but just out of curiosity why do you need that many cards and 6 displays?
I'm a multi-tasker. I'll have Adobe Premiere running on my primary display, After effects on a neighboring screen, browser in another, e-mail client in another, dreamweaver in another, and I have the final screen designated so I can fly through the files I need to find for easy drag and drop utilization. It's just the setup I like to use more than anything.
Anyway I got it to work finally in Slots 1, 3, & 7. After my last post I rebooted with no cards, added them into slots 1, 3, 5 and then magically the drivers were installed for them. I didn't do anything different which is why I am still a bit confused, but it is working now.
Anyway, time to troubleshoot my last issue. HDD in SATA slots 1-8 work fine but when I add drives to 9 & 10 my computer won't boot, it'll only show a flashing underscore. Kind of like the old issue where a WD external drive would do that on boot... but, anyway I can start a new thread for that if need be.

Having 2 NIC Cards

I have installed a second network card in my power G4 and I need to configure this card with a static IP; however, there is no where to do this (or at least I can not find it). I have the on board network card configured and working. Any suggestions?
I know if I was running os 10 then I could use UNIX commands to do this however I can not afford to do this at the present time.
Thanks
Power g4 Mac OS 9.2.x

Hi Manikandan,
You can use two network cards but if you installed B1 when this two network cards has been configured to enable, the B1 application run will have slow performance. So, you must disable one of network cards, restart the B1 server and run the B1 again.
If you need the NIC card that is already disable, you can enable again. It won't give slow performance.
my answer is quoted from SAP note 1135705:
SAP Business One takes too long to log on users
Symptom
SAP Business One client (not installed on the same machine as the
license service) might take several minutes to log you on successfully due to a delay in establishing a connection with the license server.
After logon, SAP Business One functions as expected.
This is due to the fact that the server or PC on which the license server is installed has more than one network card, or there is a dial-up & VPN interface-configured server.
Note: This can happen when you install the license service on a machine with more than one network card ALREADY installed.
Installing additional network cards on a single network card machine with a license service already installed might not produce this issue.
Other terms
SAP Business One, slow, login, log-in, delay, license, server, NIC, VPN, connection.
Reason and Prerequisites
Application error.
Solution
This issue is a candidate to be resolved in a future release.
Until then, you can use one of the following workarounds:
Disable additional network cards in the Network Connections. Also make sure there is no dialup interface or VPN interface set up, and restart the server. Note that you can re-enable the additional network card after the restart. This will resolve the issue until the next restart.
Install the license server on a machine with a single network card.
Disable all network cards, restart the license server and then enable the network cards again.

Setting Up Dual NIC Cards? Benefit?

Hello Everyone,
I know that the Mac Pro line comes with Dual NICs and I was wondering how do I set these up to be useful with my Cable Modem and Router? Can they be used to get more speed or are they used together in some other capacity.
I really appreciate anyones help and expertise.
Many Thanks,
Chris

The normal use of dual nic interfaces would be to run double instances of a given server on disparate IP numbers. Dual NIC's are generally employed in order to attach multiple IP addresses to a single machine.
Another potential use for dual NIC's is internet connection sharing, where your Mac Pro acts as a kind of router; again also this could be used for attaching one NIC to print services and the other NIC for LAN/WAN access.
OK, actually there are a whole bunch of good reasons for dual NIC cards, but 'doubling your bandwidth' is really not one of them. Believe me, unless you are on a direct fiber OC-10 20 foot from your ISP's NOC, then your existing single NIC has 1000 times the bandwidth of your incoming WAN connection.
It is likely possible to interleave dual NIC cards between two machines for bandwith purposes; but if that were going to be the canse, just identify one as "in" and the other as "out" (both machines would have to have dual NIC's to make this mean anything) but again, I honestly do not see a real world use for this...

Mulitple Oracle Homes and RAC

I want to install multiple SAP systems (SolMan, ECC, PI, etc) to a DB instance with Oracle RAC so that they can share resources and for High Availability. The central instances will be running of virtually separate systems using VMWare.
As per the white paper for doing a SAP installation with RAC, I need to install one SAP system before I install RAC. But when I do the second SAP system that creates a second Oracle_home, do I need to install RAC again? Or do I need to complete all the database installations before I install RAC?
I want to be able to share the hardware but using MCOD is out because of the many problems associated with that.

Hi Steve,
ok - I understand.
According to Oracle Metalink 220970.1 it´s possible to run more than one instance on a RAC but the resource manager will not be able to share load across the instances so one may impact the other.
That document is quite good and answers a lot of questions, also some of those, you posted in your initial question (such as if the DB software must be installed on all notes or how to convert a single instance into a RAC instance etc.)
"Note 527843 - Oracle RAC support in the SAP environment" also states, that ASM and Raw devices cannot be used in SAP/RAC-environments
This is a really nice an interesting project, technically it should be possible to implement but I can´t say, which implications will arise.

LYNC EDGE Server NIC Card Setup

Hello Guys,
I need Your help about setting up the NIC on my EDGE server. I already gone through the article about Set Up Network Interfaces for Edge Servers. as I understand there
are 2 NIC required on each EDGE server (1 Internal facing 7 another 1 is External facing). I just wanted to confirm is there any option to do this with only 1 NIC card or can we configure EDGE with 1 NIC only.?
Thanks in Advance.
Rishi Aggarwal
Regards Rishi Aggarwal

Possible? Yes, I do this on occasion against recommendations and best practices for companies who simply can't or won't set up a second DMZ (please don't split the NICs between your internal network and DMZ, it's just bad security). Everything
mostly seems to work just fine. But, recommended and supported? No.
Here's an article from David Paulino who's also been through it:

This is pretty slow, isn't it? I think the NIC card on this server is
due for an upgrade. I'm looking at the intel pro server nics.
Any other suggestions? I'm looking for a nic card that is on the HCL
