How to configure backup network in Network Load Balancing?

Some time ago I failed to find proper discription, how backup Network should be configured in NLB, because it seems to be too many options here. I´m having troubles in MBAM, its IIS autherization failing with error code 401 when dedicated FQDN adress is
used which points to NLB cluster. More information about my MBAM problem is here:
https://social.microsoft.com/Forums/en-US/a0dbe7d9-6440-42f2-99e1-21563647764f/mbam-25-installation-on-2-web-servers-as-ha-with-nlb-an-error-has-occurred-on-helpdesk-website?forum=mdopmbam
Now I need to know, what is the proper way to configure NIC and TCP/IP in NLB hosts. As I see it, there are few options but which one is the one?
1. On hosts, 1st NIC is with domain IPs, 2nd NIC is direct IP to another´s host 2nd NIC. This is the way how it should be done in Fail-Over Cluster, but this method does not seem to work witn NLB at all. Cluster adress does not respond.
2. On hosts, 1st and 2nd NIC is configured both to domain Network, same subnet. 2nd nic does not have default gateway. This method works somehow, but displays error in NLB console, when cluster is created.
3. On hosts, there is only one NIC to domain Network and no backup Network at all. This probably requires multicast mode? In MBAM HA documentation, NLB is discribed as unicast.
Hosts, meaning nodes, are 2012 R2 and located on Hyper-V 2012 R2. MAC spoofing is enabled.
- An additional side question - is it true, that NLB feature is not so reliable, and non-Microsoft hardware NLB is recommended for big companies, or
did I just mess my NLB configuration so bad?

Hi yannara,
When you use NLB cluster node with multiple NIC, you can choose different NLB mode, such as
Single network adapter in unicast mode
A cluster in which ordinary network communication among cluster hosts is not required and in which there is limited dedicated traffic from outside
the cluster subnet to specific cluster hosts.
More detail how to select NLB mode you can refer the following KB:

How to configure R/3 System with Load Balancing?

Hello,
I've created a Web DynPro Application and I would like to case an iView on it. According to SAP tutorials I first need to configure an R/3 System with Load Balancing.
My problem is how to configure the "WAS Host Name".
According to the tutorial:
WAS Host Name = <host>.<domain>:port (this corresponds to the Web Dynpro server location and the port on which it is running eg. PXYZ.wdf.sap.corp:50000.)
I am using NW 04 and my portal is running on this address:
http://ep6sp9test:50000/irj/portal
When I set the WAS Host Name to ep6sp9test:50000 the Test connection fails (I have privildges and created an alias and User mapping). What should I put at this field then?

Hi
I think you have to specify the HTTP port og the WAS running the R/3 system. The 50000 port is the HTTP port of your portal - not the R/3 system. You can see the HTTP port of the R/3 system using transactioncode SMICM - services in the R/3 system.

How to configure backup device

Hii,
I have fresh install 4.7 with sql 2000 database . I want to take backup of my database in other drive . how i will configure this drive .
thanks & regards
jagdish

hi,
you want to take backup using DB13 or from SQL server enterprise manager,
if you want to take backup on network drive the drive must be map and accessible through windows.
configure backup devices on MS SQL Server management Studio,
logon to SQL server management Studio,
under object explorer navigate through server object -> backup devices
create new backup device -- destination file type. give path for your network drive backup folder.

How to configure and test Profibus network using NI part number 780161-01 Master/Slave interface

I have purchased this board from NI. I have been in touch with Comsoft who it appears is the developer of this board. I have used the configurator II to try and build the network. The GSD file for my slave board is entered. I also can see the GSD file for the master. There appears to be no obvious way to test the bus from the configuration tool. I have tried the Express VI provided by Comsoft. Nothing happens. I have a purchased profibus cable with terminations installed. I know the cable works as another division has another Profibus master that does work using this cable How do I configure correctly for sure? How do I test?
Thanks
Rick
Solved!
Go to Solution.

Hi Rick,
First, ensure that you have the correct drivers installed on your system:
Make sure NI-VISA 4.2 or later is installed on your system.
First install 1.3x.x COMSOFT driver
Second install a DF PROFI II Slave and Master board in your PC-System.
Reboot your computer System.
Install the NI-PROFIBUS driver, instructions can be found here.
However, it sounds to me like you may have an issue with your bus configuration or with the GSD file. First, did you obtain the GSD file from the manufacturer or from profibus.com?
Also, common issues with the configuration include specifying an improper baud rate (supported baud rates can be found here), or an incorrect PROFIBUS address. Were you able to successfully save the bus configuration and generate the configuration database? Were you able to load the configuration database into the master device successfully as well?
If you are unable to resolve this issue, can you provide me with some more information about your system setup and error? What PXI chassis are you using, version of LabVIEW, operating system? What devices are you testing on the bus?

How to configure Lion Server as network time server?

I have Lion Server at the top of a small network of Windows 2K, Windows XP and Windows 7 machines.
I need each of those computers to synch their time to that of the Mac Server because this network operates without internet access.
I have tried various protocols from those machines to synch on the server's IP but they all fail.
It has led me to belive I need to enable a service to allow time synch to the managed computers.
But I can't find information on this. I keep getting directed to how to synch the mac to a time server or time machine configuration tips.
Thanks in advance

In Server Admin, select your server, click on Settings, then go to the General tab. You will see an option to enable the Network Time Server.

How to configure the drivers VGA & network wireless for Enterprise Linux 4

Hello
I have installed Enterprise Linux 4 for PC HP Compaq dc7700. The installation was successful but I cannot find linux software driver for VGA & NETWORK.
Where and how can I FIND and INSTALL the drivers VGA & NetWork for liunx Enterprise 4 .
The details of the driver for the display is

Thank you

Hi, Wesam
Please take a look the following link
http://h20331.www2.hp.com/enterprise/cache/317386-0-0-0-121.html
Generally HP compaq dc7700 is not supported with RHEL4.
so maybe you have to install their drivers manually.
For VGA driver, please refer to

How to configure Intel pci8086,109a Network dapter

/boot/solaris/devicedb/master and iprb"pci8086,109a" to /etc/driver_aliases and then
::devlinks & touch /reconfigure::
Please undo the entry in devicesdb/master. You don't need a .bef file. This was required when one used the older boot method and that too when one needed to network boot the system. With GRUB boot which available on Solaris 10 11/06 network boot is done using PXE protocol.
The problem is that Solaris does not recognize your device. The drivers are probed and attached depending on the entries available in /etc/driver_aliases. The entry the ethernet device is not in that list.
To obtain the correct entry,you would need to look at the output from prtconf -pv. Check for Intel or "Ethernet" in the output and look for the compatible properties. The entry would look something like "pci8086,1029.8086.109a". Note that actual entry should be based of the the entries from the "compatible" properties. The correct method to add an entry is use update_drv -a -i "pci8086,XXXX" Where XXXX is based on the output from prtconf -pv.

How to configure backup parallel in SAP with oracle database?

Dear SAP,
We need your suggestion on oracle database backup parallel using brbackup, our SAP system run on:
OS: UNIX - SUN Solaris SPARC 10
SAP: ECC 6.0 SR3
Database: Oracle 10.2.0.4
Our production database are growing rapidly, estimate growing is 2GB/days. Right now we backup our Production using one tape that estimated time to online backup is 4-5hours.
In there future, if we stayed this configuration. It will take long time to backup and restore it's not applicable. That's why we are planning to add more tapes during backup (4 tape parallel).
I read from help.sap, that we can configure this on $ORACLE_HOME/dbs/init<SID>.sap. in parameter:
compress = harware
backup_dev_type = tape
tape_address = (tape1, tape2, tape3, tape4)
tape_address_rew = (tape1, tape2, tape3, tape4)
http://help.sap.com/saphelp_nw04/helpdata/en/88/a2a041a5d4af4db168992639d65d3b/frameset.htm
My question,
If we want to backup parallel using 4 tapes, is this configuration that we need to do (init<SID>.sap) from sap side (DB13)?
Thanks and Best Regards,
Widi

Dear Mark,
Thanks for your help. actually I have one more question:
How do I restore my backup form this 4 tapes, if I'm using parallel backup?
Will the command same like I restore form 1 tape:
example:
brrestore u2013b beczqlnk.ant u2013m full
brrestore u2013a 5371-5372=/oracle/<SID>/oraarch/
Below are the paramter that I will configure:
- tape_address = /dev/rmt/0cbn
- compress = hardware
- backup_dev_type = tape
- exec_parallel = 4
- tape_size = 1600000
- tape_address = (dev/rmt/0mn, /dev/rmt/1mn, ..)
- tape_address_rew = (dev/rmt/0m, /dev/rmt/1m, ..)
Appreciate you help and suggestion on this.
Dear Venkat,
thanks for your suggestion

Adapter configuration & load balancing

Hi,
I posted questions for my requirements on Adapter forum but did not get any answer.
Hope this forum can help.
We started a POc with Oracle As adapters for EBS. As part of that we are trying following taks,
1) Connect to multiple EBS instances & deploy individual adapter for same on AS
2) Use these two instances for loadbalancing & scalaing
I am not bale to find information about above two in Oracle Adapter documentation.
I could build sample EBs adpater scenario with concurrent programs and use a default APPS adapter deployed on AS server by modifying oc4j-ra.xml. But failed to delpoy multiple instances that can be viwed from Enterprise Manager.
Also how to configure my adapters for better load balancing and sclaling. Is there any doc link that i can read?
Thanks in advance.

How to configure Load Balancer in front of Web Logic Cluster

hi all,
I installed 2 weblogic servers in cluster and now i want to deploy Hardware Load balancer in front of them, i want to know do i require any configuration on servers or i just deploy hardware Load balancer in front clustered servers with round robin technique.
Regards,
imran

I think there are two important configuration when you use hardware load balancer in front of WebLogic cluster.
1) Passive Cookie Persistance
You need to configure hardware load balancer so that it can identify Weblogic session cookie for routing request primary server holding HTTP sesstion.
2) External DNS
If there is firewall between hardware load balancer and weblogic cluster and NAT (Network translation ) is used, then you need to configure "External DNS" for each weblogic server in cluster. You need to specify the hostname used by load balancer in "external DNS".
More details about this are available at.

How to monitor targets which are controlled by LOAD BALANCING mechanism

Hi,
I have installed Enterprise Manager 10.1.0.3 and upgraded it to 10.1.0.5. Then i have applied the Application plug-in patch for managing Oracle Applications.In my environment, we have two concurrent managers and four forms servers which are using Load Balancer.Please let me how to manage these concurrent managers and forms servers in that scenario.Would highly appreciate your suggestions regarding the same.Thanks in advance.
Regards,
Vamsi Manyam

This note shows how to configure OEM behind a load balancer.
The question was how to use OEM, not behind a load balancer, to monitor other targets which are behind one or different load balancers.
For example, to monitor :
Forms on server A and B behind load balancer LB1.
Forms on server C and D behind load balancer LB1.
Forms on server E and F behind load balancer LB2.
