Can I use VIP to load balance Coherence Extend?

Hi,
It is possible to provide a list of remote addresses for a remote cache configuration as shown below:
<remote-cache-scheme>
<scheme-name>remote-scheme</scheme-name>
<service-name>ExtendTcpCacheService</service-name>
<tcp-initiator>
<remote-addresses>
<socket-address>
<address>server1_IP</address>
<port>35501</port>
</socket-address>
<socket-address>
<address>server2_IP</address>
<port>35501</port>
</socket-address>
</remote-cache-scheme>
Now is it possible to use a VIP instead of individual IPs for the same purpose?
I tried it and failed. The error was caused by "RequestTimeout". I verified the VIP configuration and it was correct.
Does anyone have similar experience?
Regards,

I haven't worked with VIP, but my vague recollection regarding VIP is that:
(1) A VIP address can only be bound to a single server as it's primarily a fast failover mechanism, so you'd still need a set of them.
(2) VIP isn't intended to be used without CRS. As Coherence includes its own cluster management stack, it would be unusual to configure CRS as well.
One would normally use a general purpose loadbalancer (HW or SW) to achieve your goals, which is a supported configuration.

Can I use LabVIEW to load data directly into system memory? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Win32 function to read the data from the card and now I want it to go directly to system memory.

Can I use LabVIEW to load data directly into system memory from a VI? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Call Library function to read the data from the card and now I want it to go directly to system memory.
The data is being received at 1Mbps.
Thanks

Two questions:
One, if it's a serial card, then presumably it gives you more serial ports, like COM3, COM4, etc. If so, VISA would see the COM ports, and not the card directly. The drivers for the card should make it so that you see the extra serial ports from the OS. If you don't see the extra COM ports from VISA, then it sounds like the drivers for the card are not installed properly. Do the extra COM ports show up in Device Manager?
Two, you said that you're using a Call Library function to get the data and you want to put it into system memory. Errr.... you just read the data and you have it in memory by definition. Are you saying you need a way to parse the data so it shows up on a graph or something?

Is it possible to use Apache with load-balancer ?

Hello,
I'd like to know if it's possible to set up a load-balancing solution made of: Apache Web Server + Hardware Load Balancer+ Cluster of Weblogic Nodes.
In the documents I see Apache server is used only with the HTTP Proxy plugin. But I'd like to use the hardware load balancer to ditribute load to Weblogic nodes.
Is it possible to do it ?
Thanks
Francesco

Hi,
The configuration you are talking about is possible. All the information is here http://edocs.bea.com/wls/docs81/cluster/load_balancing.html#1026240 , and here http://edocs.bea.com/wls/docs81/cluster/bigip.html#618892

Using CSM to load-balance two sites

Hi there,
I currently use CSS11500's at two of my sites and I'm able to use source-groups to achieve site load-balancing behind a single VIP. So basically I have a VIP that has servers in both the local site and remote site. Is something like this possible with the CSM? I suppose there's the nat server or nat client commands, but I'd like to be able to maintain original client IP address if possible, or at least maintain the original client IP for connections that stay local to the site.
Thanks,
Brandon

Hello Brandon-
It is not directly possible to pick and choose what servers are natted on the CSM like the CSS and ACE can do.
In the CSM, you configure nat under the serverfarm specifically.
Ex.
serverfarm Client_Nat_Example
nat server
nat client REMOTENAT
real 10.10.10.1
inservice
natpool REMOTENAT 172.16.35.5 172.16.35.5 netmask 255.255.255.0
If you were to devide up the traffic prior to hitting a serverfarm (maybe use a policy that matches specific subnets for your clients), then you could nat to only certain servers.
Ex.
access-list 2 permit 5.5.0.0 0.0.255.255
serverfarm Client-Nat-Example
nat server
nat client REMOTENAT
real 10.10.10.1
inservice
serverfarm No_Nat
nat server
no nat client
real 20.20.20.1
inservice
natpool REMOTENAT 172.16.35.5 172.16.35.5 netmask 255.255.255.0
policy client_remote
serverfarm Client_Nat_Example
client-group 2
vserver HTTP
virtual 172.16.35.7 tcp www
slb-policy client_remote
serverfarm No_Nat
persistent rebalance
inservice
With this config, the CSM checks global access list 2, anything that matches a source of 5.5.x.x subnet would go to the serverfarm with the remote servers. Anything that does not match 5.5.x.x would use the default serverfarm under the vip (No_Nat serverfarm). This is not optimal, but there is no parity between CSM and CSS when it comes to per-server NAT.

Using ACE to load balance HTTP/S traffic between client & proxy server using tcp 8080

Folks,
I have a scenario where ACE is in load balancing connections to a bunch of Websense servers in a one-armed topology. ACE presents a single VIP to web browser clients and each client's browser proxy configuration is populated with the VIP DNS name. Traffic then gets load balanced between the Websense servers. The problem arises due to Websense requiring the 'X-Forwarded-For' HTTP header in order to obtain the source IP of the client.
ACE inserts this header into the standard HTTP 'proxied' traffic but doing this for HTTPS traffic has required the configuration of the ACE SSL proxy client server.
So the problem I have is this:
How to configure ACE to load balance both HTTP & HTTPS applications using a single VIP and tcp port number ie tcp 8080
The ACE hardware being used is ACE20-MOD-K9 - MODULE
I have attempted to use a L7 class map to match all ciphers and attach this to a L7 Policy-Map but the documentation highlights the fact the 'match cipher' configuration is only available on the ACE appliance.
I believe I am on the correct track. The HTTPS traffic must be identified and used to match against PolicyA and HTTP traffic matched against PolicyB
I'm looking for ideas! I'm hopeful someone must have solved this problem previously!!
Regards,
Simon

Hi Simon,
The classification has to work on different ports. Whether client types http or https doesn't matter to client. His request will reach VIP which will classify the traffic based on port, protocol first and then it can look into further detail to send the traffic to appropriate serverfarm.
You can class-map match-any xxxxx
2 match virtual-address x.x.x.x tcp any
and then you configure further classification on the basis of L7 like url, header etc.
But again, you will still need SSL termination on ACE.

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.

Using CS150 to load balance

Using the CS150 to load balance between two or three servers, want to filter the HTTP url that is returned from the server to the client. It is showing the port number and a login.... ie.
http://weblogic:771/login.asp
I want to remove the :771/login.asp
Any ideas? Having a hard time finding any documentation on Cisco web site.
Bill

Bill,
In general, the CSS will NOT modify a URL being sent to a client from a server. The can send a "redirect url" back to the client given certain criteria coming in from the client. As far as return traffic to the client from the server, the CSS simply routes or mac forwards the data without any manipulation of the url. The only thing the CSS will modify is the ip address of the server in a NATing senario.

If you haven't done this before, there are a few things you need to know. Sorry to say that this is not yet a simple, straightforward process like it is for music CDs. It helps to be a little geeky. You will need to make some choice about file format and file size if there is any chance that the imported discs will take up more space than you have available on your hard drive. If you are willing to learn, you should read the Handbrake User Guide and other articles on the Web about importing DVDs.
If you think this is starting to look complicated and you don't have time to figure it out before the trip, it might be easier to just bring the discs.
I have found that Handbrake can't import every disc. I think Mac DVD Ripper Pro is a much easier program to use, and it will import almost any DVD pretty reliably, but it costs money. For me it is worth it.
No matter which way you do it, it is going to take a lot of time to import a bunch of discs. It is going to take a lot more time than importing music CDs.

Email send issue using "Mail Server Load balancer" (Cisco ACE 20)

Please let me know if someone have experienced this kind of issue or any suggestions.
The send email action was working file in MII with smtp mail server on port 25. Recently basis did a change in mail server ip address and they installed a new Load Balancer . The Load balancer is between SMTP and MII. After this change MII does not send email (unknown source error). now MII send email action has ip address or qualified path of Load balancer in MII send email configuration instead of direct ip address of SMTP server. Below is the error message in Net Weaver logs.
MII still sends email if direct ip address of email server provided but not through email Load balancer .
Any suggestions ?

Using StoneBeat WebCluster load balancing with WebLogic

          Hi,
          I have done some testing of WebLogic Server with my company's StoneBeat WebCluster
          distributed load balancing software. This might be one more option to consider
          as a load balancing solution for WLS. It is advanced in the sense that load balancing
          is really dynamic, there are no single-points of failure (distributed architecture)
          and there is a very good, configurable test subsystem that runs on each cluster
          node to check for overload situations, HW/OS failures, ...
          In the initial testing, the WebCluster load balancing works with WebLogic replication,
          although there are some cases that need mroe consideration (please see below).
          I had to get a patch to WLS6SP1 on NT to make WLS' multicast work when there are
          several NICs on the cluster nodes.
          However, there is one case which causes problems:
          - I have 3 cluster nodes
          - P: 2, S: 3 (SessionServlet = 1)
          - 2: offline - P: 3, S: 1 (SessionServlet = 2; WebCluster randomly selected a
          new node to handle the connection)
          - 2: online - P: 2, S: ? (SessionServlet = 3, WebCluster redistributes the load
          when a node goes online)
          - 2: offline
          - P: 3, S: 1 (__SessionServlet = 1__) NB!
          The log messages show that when node 2 comes back online it retrieves the replica
          from the secondary (node 1) and not from the primary (node 3). After a while (5-6
          minutes), node 3 tries to update the replica on node 1. Node 1 considers this
          a stale update request and removes the Primary 16... (node name) and then the
          secondary for 16... (the replicated object). Then there's a message (still on
          node 1) that it is unable to find object 16... Back on node 3 the primary for
          16... is removed.
          From the WLS6 documentation (under the discussion of using replication with external
          HW load balancing solutions) I thought that this case would have been handled:
          - it is stated that after the failure of a node, if the HWLB box sends the next
          request to a node where there is no replica, WLS is able to retrieve the replica
          - to be fair, this is what happens: when node 2 came back online, it retrieved
          the replica from node 1 (the secondary) - I suppose that there is an assumption
          that if a request arrives to a node without a replica, the primary __must have
          failed__
          Is there any way to get around this problem?
          Admittedly, WebCluster has a problem in that the stickyness of connections is
          not perfect: - when a node goes online, a connection that was correctly persisted
          (based on either source-ip or source-network address) may be moved to a new node
          since the load is redistributed. Our load balancing is very dynamic, but doesn't
          maintain a list of who is connected to which node when resistribution takes place
          Regards,
          Frank Olsen

Rick,
You may want to look at the Alteon and F5 configuration we have on edocs.
Take a look at the following URLs for a possible solution

Using AE with Load Balancing Router?

Hi,
I have two Adsl cable from differents ISPs and one Airport Express (AE), I'm using one adsl in AE and wireless from AE works normaly, when the adsl link fails I change to another ADSL cable. I bought a Dlink DI-LB604 (Load Balance Router) that has 2 Wan ports to receive the two ADSL cables that I have. My question:
Will the Wireless network work if I connect my AE in to Dlink Router using Ethernet cable?
Tks

fsoato, Welcome to the discussion area!
My question: Will the Wireless network work if I connect my AE in to Dlink Router using Ethernet cable?
It should. It shouldn't be any different than connecting it to any other Ethernet connection.

Iview contents missing when using FQDN Cisco Load Balancer

Hello Experts,
We are using Cisco load balancer to distribute the load across the portal servers. Everything was working fine, but after upgrades to the latest support package stack SP18, we ran into some odd behavior. Some of the contents on the iview are blank when using FQDN load balancer URL e.g. http://sap1234.corp.com/irj/portal . But those blank contents does show up if we donu2019t use FQDN e.g. http://sap1234./irj/portal . At this point we are not sure where to start troubleshooting?
Any helps would be appreciated,
Dave

Isn't this the same as your other post? I'm locking this one...

Can I use VIP to load balance Coherence Extend?
