Using the network load balancing from the nodes itself

I have installed a 2 node Sun Cluster 3.2, configured a shared ip resource and attached to it a scalable network aware resource working on the two nodes. I have crashed the process on one of the node in such a way that the cluster could not restart it again
In this status I tried to open a connection from another server and the load balancer always sent the traffic to the node that was up which is as expected...
If I try to open a connection from the node on which the process is failed then I get a connection refused meaning that the load balancer is not working in this circumstance.
Is this a bug/ a mis-configuration/ or just an inherent cluster problem.
Is there a solution to this issue?
Regards
Daniel

To answer your first question, no, there isn't anything you can do.
Here is what my colleague suggested while I was away:
Zone-clusters scalable services still require shared-IP zones, which means requests from one app to another would still bounce back due to loopback. Probably wouldn't help here.
They could isolate the services that must talk to other services into their own failover group on exclusive-IP zones. Other services can be setup as originally planned. But maybe there are too many such "dependent services" for this to be useful. Also, each failover service must have its own IP address.
Finally, can these web services be configured so that it tries multiple addresses. In that case, if the shared address foo for service X bounces back (due to X having crashed on the local node), the app itself would retry with address bar for service X? This allows for uniform configuration across all services, namely:
    - try shared address
    - try node 1's own address (either public or clusternode1-priv)
    - try node 2's own address
You can fine tune it so that configurations on node 1 only use node 2's address as backup, and vice versa. I don't know if that is any help.
As for your second question, the answer is that Solaris Container Clusters allow for consolidation and isolation of clusters onto a single set of nodes. Normal containers don't really allow you to consolidate complete clusters in quite the same way. See http://www.sun.com/offers/details/820-7351.html for more.

Microsoft Network Load Balancing on the SG-500

Hello,
I wanted to know if the Microsoft Network Load Balancing can also be configured on the switch SG-500? and if so, how?

Hello,
From everything I have read about this service, it is independent of hardware, the configuration is all done on the servers themselves.
Source I used: Microsoft Network Load Balancing Technical Overview
The section on Ease-of-use talks about there being no hardware changes required for this to work.
Hope that helps and thank you for choosing Cisco,

Load balancing from the BI portal

Hi everybody,
We have a BW system with two application servers.
When we use BEx, the load balancing leads the user to the application server that is used less.
When we use the portal, everything goes over the central server.
Does anybody know how we can set up load balancing from the BI portal ?
Kind regards,
Marc van Eijndt

The web dispatcher for your portal should do the load balancing... usually the scenario is the other way round - BEX tends to use the server irrespective of its load and Portal will hit the load balancer and hence lead to better performance ....

MPLS/VPN network load balancing in the core

Hi,
I've an issue about cef based load-balancing in the MPLS core in MPLS/VPN environment. If you consider flow-based load balancing, the path (out interface) will be chosen based on source-destination IP address. What about in MPLS/VPN environment? The hash will be based on PE router src-dst loopback addresses, or vrf packet src-dst in P and PE router? The topology would be:
CE---PE===P===PE---CE
I'm interested in load balancing efficiency if I duplicate the link between P and PE routers.
Thank you for your help!
Gabor

Hi,
On the PE router you could set different types and 2 levels of load-balancing.
For instance, in case of a DUAL-homed site, subnet A prefix for VPN A could be advertised in the VPN by PE1 or PE2.
PE1 receives this prefix via eBGP session from CE1 and keep this route as best due to external state.
PE2 receives this prefix via eBGP session from CE2 and keep this route as best due to external state.
                             eBGP
                     PE1 ---------CE1
PE3----------P1                          Subnet A
                     PE2----------CE2 /
                            eBGP
Therefore from PE3 point of view, 2 routes are available assuming that IGP metric for PE3/PE1 is equal to PE3/PE2.
The a 1rst level of load-sharing can be achieve thanks to the maximum-paths ibgp number command.
2 MP-BGP routes are received on PE3:
PE3->PE1->CE1->subnet A
PE3->PE2->CE2->subnet A
To use both routes you must set the number at 2 at least : maximum-paths ibgp 2
But gess what, in the real world an MPLS backbone hardly garantee an equal IGP cost between 2 Egress PE for a given prefix.
So it is often necessary to ignore the IGP metric by adding the "unequal-cost" keyword: maximum-paths unequal-cost ibgp 2
By default the load-balancing is called "per-session": source and destination addresses are considered to choose the path and the outgoing interface avoiding reordering the packets on the target site. Overwise it is possible to use "per-packet" load-balancing.
Then a 2nd load-sharing level can occur.
For instance:
         __P1__PE1__CE1
PE3           \/                   Subnet A
        \ __P2__PE2__CE2
There is still 2 MP-BGP paths :
PE3->P1->PE1->CE1->subnet A
PE3->P1->PE2->CE2->subnet A
But this time for 2 MP-BGP paths 4 IGP path are available:
PE3->P1->PE1->CE1->subnet A
PE3->P1->PE2->CE2->subnet A
PE3->P2->PE1->CE1->subnet A
PE3->P2->PE2->CE2->subnet A
For a load-balancing to be active between those 4 paths, they must exist in the routing table thanks to the "maximum-path 4 "command in the IGP (ex OSPF) process.
Therefore if those 4 paths are equal-cost IGP paths then a 2nd level load-balancing is achieved. the default behabior is the same source destination mechanism to selected the "per-session" path as mentionned before.
On an LSP each LSR could use this feature.

Trying to find the Network Activity number from the CATSPS table

Hi Experts
I am trying to build a report to show unprocessed time on Network Activities. The time is entered via CAT2 and transferred to CATSPS via the CATA job.
Once the data hits the table, an internal system number is given to activity.
I have the following example:
Say I have three Network Activities all linked to the same Network and WBS as follows:
Network   Activity #
43000121 0001
43000121 0002
43000121 MTS
When I post time against the 2nd and 3rd NWAu2019s, CATSPS has the following entries:
RNPLNR               RAUFPL                RAPLZL
000043000121    0000000182         00000002
000043000121    0000000182         00000003
Now the RAPLZL field has no visual link to the NWA.
Does anyone know of the Internal table that holds the link between the RAPLZL field and the Activity that is represents.
I have already looked at PLPO (no entries).
Any other suggestions would be appreciated.
Thank you in advance

Match the entries RAUFPL, RAPLZL of CATSPS with AUFPL, APLZL of AFVC table, you will get the activity number(VORNR)

Using Microsoft Network Load Balancing for Livecycle ES 2/2.5 with JBoss clustering?

Hi,
Has anyone tried using Microsoft NLB for Livecycle with JBoss clustering and get it working? Able to login to livecycle's admin ui page with the NLB IP
My enviroment:
- 2 jboss application server (different IP address)
- Horizontal clustered
- LC ES2 installed on both servers
For those who setup successfully, hope you can share your experience.
Thank you.

Thanks!
Just a few more questions...hehehe
In the document: Configuring LiveCycle ES2 Application Server Clusters Using JBoss.
Page 35 item 3.4. Have you had to configure the Caching Locators? If yes, where did you put them, in only one machine or in all of the nodes?
On page 29, iten 2.7 (Testing the JBoss Application Server cluster) says that for testing we can run the command specifying the server, in my case is:
run.bat -c lc_sqlserver_cl -b <ipAddress>
But in the Appendix C: Configuring JBoss as a Windows Service, it says: call run.bat -c all -b <ipAddress>
So when should I start JBoss with "lc_sqlserver_cl" or "all" ?

Network load balancer for Agentry applications

Hi Expert,
I'm going to implement a SAP Mobile Platform solution that will use an agentry application and I need some clarification about the HA configuration and the usage of the network load balancer and relay server. Just for information I'm going to use SMP 2.3 SP4.
My understanding is that Relay server is a reverse proxy and load balancer for SMP but It can't be used for the agentry applications. Is this correct?
Based on the standard configuration in order to balance the load of the client devices in the SMP cluster I have to use a Network load balancer, therefore the technical architecture of my solution should be the following:
|Agentry Client device| ----> | Network Load Balancer | ----> | SMP and Agentry Cluster| -----> |Back end systems|
Is this correct? I didn't find specifications about the Network load balancer.. Is there a list of the Network load balancer products supported from SAP for agentry application. Is there any best practice on the network load balancer?
Thank you in advance for you collaboration.

Because we don't test any directly with our QA we don't have have a preferred products. Talking to our consulting group they normally just use what the customer already has installed in their network. Both Software or hardware load balancers has been used.
The key part needed for the load balancer for Agentry 6.0.x and SMP 2.3 (not SMP 3) that it is set to TCP Pass through.

How to enable Network load balancing for Enterprise portal

Hello,
We have installed EP 7.0 central instance(00) and dialog instance (01) and would like to enable network load balancing between these two EP servers.Have installed network balancer and the configuration has been done at network level.
The below URLs are being used for accessing the portal
Central instance :
http://CIhostname:50000/irj/portal
Dialog Instance:
http://DIhostname:50100/irj/portal
Both the port number has to be same for enabling load balancing.In order to acive this we have to map this port to http port by making some changes in Visual Administrator.
Can you please let me know step by step procedure or any link where i can find the same?
Appreciate your response
Thanks,
Vadi

Dear Jay,
Thnaks for your reply.
No...NLB will helpful in load balancing between different 2 different application (Ep)servers.
We are using microsoft network load balancer.Found the service http provider in VA for making those changes.
Any way thanks.

Network Load Balancing - "access denied" when loading configuration information from host2

We have 2 Windows 2012 R2 servers, both are running on workgroup.
We set up NLB cluster. When we open NLB Manager on the server2, then message shows "loading configuration information. Access denied. Error connecting to server1".

Hi Zhong Gang,
When you are using Network Load Balancing (NLB) Manager, you must be a member of the Administrators group on the host that you are configuring, or you must have been delegated
the appropriate authority. If you are configuring a cluster or host by running NLB Manager from a computer that is not part of the cluster, you do not have to be a member of the Administrators group on that computer. Please disable your nodes firewall and
try again.

Bug with Network Load Balancing Services and SkipAsSource always reverting to true

Steps to reproduce:
Add an IP address to the cluster (2 nodes running Windows Server 2012) using the Network Load Balancing Manager
Using PowerShell set the SkipAsSource flag on the IP Address to true (Set-NetIpAddress -IpAddress 192.168.1.10 -SkipAsSource $true). The flag is correctly set.
Try to reverse the setting (Set-NetIpAddress -IpAddress 192.168.1.10 -SkipAsSource $false). Flag stays as true.
It appears as though Network Load Balancing Services is remembering the setting from someone.
Things I've tried all without success (in no particular order):
Removing the IP address from the cluster and adding it back in
Using PowerShell to remove the IP address and add it back in manually (on each host).Flag stays set as true on the 1st node but takes a second before it reverts back to true on the 2nd node.
Using netsh to remove the IP address and add it back in manually (on each host). Flag stays set as true on the 1st node but takes a second before it reverts back to true on the 2nd node.
Deleting each host from the cluster (one at a time), removing the registry keys CurrentControlSet\Services\WLBS and
Removing both hosts from the cluster
Restarting the hosts
Using processmon (sysinternals) to try and find a registry entry that might be set when SkipAsSource is set
Does anyone know:
How to resolve this issue? I'm guessing resetting the TCP/IP stack would work but that's a last resort as it requires an on sight visit to the datacentre.
Where the SkipAsSource flag it stored?
How to reset the master/global cluster config?
Thank in advance,
Antony

Multicast not working with Window2K Network Load Balancing.

I'm using W2K Network Load Balancing (WBLB) for our cluster machines (2
          boxes) to load balance between IIS (one IIS instance on each box). Each IIS
          instance is a proxy to the weblogic cluster (one app server instance on each
          box). Currently I only have a single network card configured for each box,
          so I have had to enable multicast support for the WNLB. But if I do this
          I'm unable to get multicasting working correctly for the weblogic cluster.
          When I run the multicast tester (utils.MulticastTest) one box is able to
          receive multicast messages from both boxes, but the other box is only
          receiving multicast messages from itself (but not the other box). Does
          anyone have any experience with configuring weblogic clustering on machines
          with WNLB also configured?
          Thank you.
          Marko.


Hi
NLB return traffic for UDP would come from the node IPs.
You could use NAT on your firewalls so they come from the same public IP.
Otherwise you'd be looking at something other than MS NLB.

Windows Network Load Balancing - Virtual MAC Address

Hi All,
I have environment that running 2 Exchange 2010 server with CASHT and join windows network load balancing as a node.
My question is,
If NLB service is restart, is it virtual MAC Address for NLB will change to new virtual MAC Address?
Thanks for response,
Best Regards,
Henry Stefanus

Hi Henry Stefanus,
The NLB work mechanism will not change whether what higher application we used and I am not very familiar with Exchange NLB architecture, may the following KB and article
may help you.
When you use the unicast method, all cluster hosts share an identical unicast MAC address. Network Load Balancing overwrites the original MAC address of the cluster adapter
with the unicast MAC address that is assigned to all the cluster hosts.
When you use the multicast method, each cluster host retains the original MAC address of the adapter. In addition to the original MAC address of the adapter, the adapter is
assigned a multicast MAC address, which is shared by all cluster hosts. The incoming client requests are sent to all cluster hosts by using the multicast MAC address.

Hyper-V 2012 R2 & NLB (Network Load Balancing) with Unicast on VMs

Hi,
We set up a 2012 R2 Hyper-V Cluster. On this Cluster we would like to run 2 VM's which are using NLB (Network load Balancing) in Unicast mode.
We have created a External Virtual Switch wich is connected trough a 3x10GB LACP Team to a Cisco Nexux Switch.
We have tried to set the NLB up in the way we did with 2008 R2 but we were not be able to get this working. Is there any Change in 2012 R2 we did not think about?
Each time we form the Cluster one Node becomes unavailable.
Timo

Check the virtual network adapter properties - you must enable MAC address spoofing. We had the same issues.
Note that this will absolutely pollute your host machine's system log with tons of spam and make it pretty much worthless. I'm trying to find a way around this as we speak, actually.

Network Load Balancing and failover for AFP Sharing

Dear all,
Somebody kindly teach me to use round robin DNS to perform the network load balancing, it's success but not the failover.
I have 4 xserve and want to do the load balancing and failover at the same time.
I have read the IP failover document and setup it successfully, but anyone know is it possible to do the IP failover for more than 2 server?
For example, 4 server serving the AFP service at the same time, maybe I have 1 more extra server to do the IP failover for thoese 4 servers.
As I know, IP failover require Firewire as the heartbeat detection. But one xserve only have 2 firewire ports. May I setting up the IP failover only by a ethernet port and an IP address? does it possible to detect and failover to any server after server down has been detected?
I believe load balancer maybe the best solution but its cost is too high.
Thanks any advance!
Karllee

well, u have 2 options here
software load balancing
request comes it foo.com -> ws7u2 hosting foo.com is configured to run as reverse proxy . this server sends any incoming requests to one of the four back end web server 7 handling your incoming request
hardware load balancing (this you need to invest)
request comes to hardware load balancer who responds for foo.com -> sends requests to four ws7 server hosting your application
you could try out how software load balancing works out for you before you invest in hardware load balancing
here is more instruction on configuring ws7 + reverse proxy (software load configuration)
- install ws7 on foo.com
- create a new configuration (choose port 80, disable java

Network Load balancing for Server 2003 and Server 2012

Our environment currently has 2 web servers running Windows Server 2003 with Network Load Balancing. We are looking to update the servers to Windows Server 2012. Is it possible to add Windows Server 2012 into the Windows Server 2003 Network Load
balancing cluster? This way we could bring up 2 new servers add them into the network load balancing and then take out the 2003 servers without disrupting our production.
Any thoughts or suggestions on how to make this work properly?

Hi,
You can upgrade an existing Network Load Balancing (NLB) cluster to Windows Server 2008, Windows Server 2008 R2, or Windows Server 2012 by taking the entire cluster offline
and upgrading all the hosts, or you can leave the NLB cluster online and perform a rolling upgrade. A rolling upgrade entails taking individual cluster hosts offline one at a time, upgrading each host, and returning the host to the cluster. You continue upgrading
individual cluster hosts until the entire cluster is upgraded. A rolling upgrade allows the cluster to continue running during the upgrade.
