GSS load balancing ? Only one GSS seems to answer

Hi,
We have configured two GSSs but only one of them seems to respond to DNS requests, I see this via the answer hit counts.
The box that answers is NOT the GSSM Primary. I was under the impression that both boxes could/would respond or is this not true.
Any facts would be appreciated. Cheers.
Mike

The RoundRobin balancing will not be a perfect distribution if you use the AP-KAL mechanism for your keepalive. This is because when the load on the answers changes, the "order" is sorted, and the top of the sorted list is used for the next answer even though the sorted order is of no interest in a roundrobin balance.To get a perfect roundrobin balance, use a different keepalive.

  • Load Balancing only working on one server!

    Hi All,
    I have configured 3 servers as follows:
    Server 1 = WebCache only server (Windows 2003)
    Server 2 = 10g Forms and Reports server (Solaris)
    Server 3 = 10g Forms and Reports server (Solaris)
    Servers 2 and 3 work perfectly using the direct addresses on the following ports
    server2.domain.com:7778/formsurl?config=WEBTEST
    server3.domain.com:7777/formsurl?config=WEBTEST
    I have added the Origin servers, the site definitions, and the one site-to-server mapping which is as follows:
    server1.domain.com:7777
    --> server2.domain.com:7778/formsurl?config=WEBTEST
    --> server3.domain.com:7777/formsurl?config=WEBTEST
    When connecting using the WebCache server's URL I get a FRM-92101 error, cannot communicate... I am using the URL below to connect:
    --> server1.domain.com:7777/formsurl?config=WEBTEST
    However, if I remove one of either server2 or server3 from the site-to-server mapping (effectively meaning that WebCache is only 'load-balancing' on one server), the application loads up fine.
    It is only when enabling both servers that it fails?!?!
    Does anyone have any ideas as to what could be happening to cause this problem??
    Many thanks,
    Paul

    Thanks for all the replies ;)
    I have now fixed the problem...Dont ask me how because it would take too long to explain!
    Thanks,

  • Clustering for load balancing only

    I wish to set up 2 WLS 8.1 machines to run an application independently to
              share load (no replication of sessions, beans etc).
              Can I create a cluster for the two servers and not turn on any session or
              bean replication, then configure the IIS or Apache plug-in to use the
              cluster and therefore create some load balancing?
              Chris
              

    Chris,
              Yes you can certainly use a Cluster simply for load balancing. There is no
              mandate that you have to take advantage of session state replication in the
              cluster.

  • Server Load Balance in one network using CSM Cat6509

    I have 2 Web Servers with real IP address 10.1.12.61 and 10.1.12.62 (subnet mask 255.255.255.0). The virtual IP address configured on CSM is 10.1.12.100
    I also have 2 Application Servers with real IP address 10.1.12.81 and 10.1.12.82 (subnet mask 255.255.255.0). The virtual IP address is 10.1.12.120.
    Users will access Web server using the virtual IP address (10.1.12.100) so that the traffic will be load balanced.
    But there is also requirement that those Web Servers access Application Servers using IP address 10.1.12.120 so that the traffic will be load balanced as well.
    Is this requirement feasible?
    Can CSM load balance between servers in one network address?

    Budiman,
    I am building the same situatiuon here. But the most simple part seems not to be working. I have two webservers in the same subnet as my VIP.
    The clients can be everywhere in every subnet.
    This is what happens:
    btpebgw70#sh mod contentSwitchingModule 9 conns
    prot vlan source destination state
    In TCP 401 192.6.53.42:1901 151.183.58.196:80 ESTAB
    Out TCP 401 151.183.58.196:80 192.6.53.42:1901 ESTAB
    ok this is good but:
    btpebgw70#sh mod contentSwitchingModule 9 reals detail
    151.183.58.201, ORBIS, state = OPERATIONAL
    conns = 0, maxconns = 4294967295, minconns = 0
    weight = 8, weight(admin) = 8, metric = 0, remainder = 0
    total conns established = 58, total conn failures = 58
    the failures have the same value as the established. Can you send me your config part of the csm because I am getting tired of this. Please email to [email protected]
    Thanks in advance!

  • Apache HTTP proxying for load balancing only to a group of non-clustered WL servers

              Hi,
              We're running WL Server 6.1 SP 2 on Solaris 2.8.
              For the Apache HTTP proxy plugin, if you use the WebLogicCluster http.conf option,
              do the WL servers you want to load balance across have to be part of a WebLogic
              cluster (if you are prepared to do without failover, as I know it would need to be
              a proper WL cluster to replicate session info for failover). Can you load balance
              across a group of non-clustered WL servers, and maintain the user session to the
              one WL server so that it doesn't switch between servers on alternate requests for
              the same user session, or must the servers be configured as a WebLogic cluster?
              Paul
              We find that if you have a collection of WL servers that are not configured as a
              cluster, that it will load balance alternate requests to each server, but it will
              not pin a user to a single machine according to their session so for 2 servers, 2
              differetn sessions get created, one on each machine.
              Is this because it doesn't normally do this, but sends the user alternately to a
              primary then secondary which works in a cluster because the session is replicated.
              I thought the secondary was only used when the primary failed.

              You don't have to use the clustering option. To get failover, you'll have to
              use the JDBC persistence option of WL.

              The primary/secondary stuff requires clustering. If Apache continues to
              "load balance" after the first request, you need to either use JDBC session
              persistence or use a different load balancer (like mod_jk for Apache or a
              h/w load balancer with support for sticky).

  • Internet Problem - One site will load, another won't. Then mintues later, the site that previously would load won't and the one that wouldn't will. I'm also pulling up a lot of pages in all text. Pics won't load or only one will load and the rest won't...

    Several weeks ago, I began to have some very strange internet connection issues. All the lights on my modem stay on and my computer shows full wi-fi signal, but I suddenly I won't be able to load any pages. Other times, I'll be able to load pages from one site, but not another. It's not the same sites all the time though.... sometimes I'll be able to load pages from one site and not another, and then 5 minutes later it'll switch and I'll be able to load pages from the site I previously couldn't and I won't be able to load pages from the site I previously could. A lot of pages are coming up just text with no pics... and then 5 mintues later that site will load normally and another site will come up just text. It does the same thing whether I'm connecting wirelessly or via an ethernet cable. It also doesn't matter which browser I use (I've tried Safari, Chrome, and Firefox). Although, once in a while when using chrome, I get a DNS error page instead of the usual 'cannot find server'. I contacted my service provider and I'm not losing speed or dropping packets. According to them, the problem I'm having is very strange since diagnostic tests show no problems at all. Perhaps someone has run into this before and has a suggestion?

    Then if you have tried all the browsers try connecting the system to yoour router with an Ethernet cable and turn WiFi off. If you have the same problem then it more then likely after your computer, Router or modem or connection from your ISP.
    If you get good browsing with the Ethernet cable then it is either the WiFi card in your Mac or the WiFi system in your router.

  • Firefox is loading plugins from both default directory and my home plugin directory. How do I tell it to load from only one place ?

    I log on to a Linux server that my IT group set up. They have a directory ../firefox/5.0/plugins and , as expected, there is a link to java . However, I wanted to use a differnent version of Java. So I created a directory in ~.mozilla/plugins and created a link to the versionof java I wanted. When I checked, Firefox had both versions installed. I can manually disable, but I rather there was a way to override, not compliment, the default plugins.

  • ACS load balancing

    if i have CSS and i want to load balance between 2 ACS . do i have to make one of them active and seoncde backup or i can load balance between bother server .
    if yes is this will not effect the authentication and databse .
    if there is any artical it wile be more better

    Hi,
    Cisco ACS has a replication feature that allows you to have more than one (1) ACS servers/appliances to provide high-availability/ redundancy. In this case, you will have one primary and more than one secondary (backup) servers.
    The database replication creates mirror systems of ACSs by duplicating parts of the primary ACS setup to one or more secondary ACSs. Without load-balancer, you need to add both primary and secondary ACSs in all AAA clients as backup if the primary ACS fails or is unreachable. With a secondary ACS whose ACS internal database is a replica of the ACS internal database on the primary ACS, if the primary ACS goes out of service, incoming requests are authenticated without network downtime, provided that your AAA clients are configured to fail over to the secondary ACS.
    The following url provides you with details on how the ACS replication is performed:
    http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/acs40/user/sad.htm#wp756102
    http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/acs40/user/index.htm
    I am not sure about load-balancing two ACSs, but you probably can try this. Behind a load-balancer, maintain the primary/secondary server setup to enable replication (selected items only) from primary to secondary ACS. But pls bear in mind, in replication, only the Primary ACS can send update to backup server, not bidirectional. Backup/secondary ACS can only receive updates. Use the replication features as an update tool between the servers. All changes/updates must be made in your primary ACS only.
    In normal ACS replication, all AAA clients need to specify primary and secondary ACS server as backup. With load-balancer, only one (1) IP need is required, which is the virtual IP assigned by load-balancer to represent the two ACSs.

  • Multiple WAN connections all through one router with load balancing?

    I am setting up a network in my dormatory for myself and about 20 friends. about half of us have DSL connections at the moment. Is there a way to have all the DSL connections (possibly run through cheap home DSL routers) all connect into a cisco router that then acts as the gateway for our entire network? woudl it be possible for each internet request to go out over the connection that has the least load AND also be able to use some sort of load balancing, so one user cant use all of the outgoing/incoming bandwidth?
    If you have any ideas please let me know

    Hi Ian,
    To get this working, you would either need to use something like PPP to bundle your links together or use a dynamic protocol.
    In bundling the links, you could make them appear as one link, with a single IP address each end and the router takes care of distributing the load. To implement this though, you would need control of both sides of the link, or be terminating with one carrier who is happy to implement this for you.
    The second is to use a dynamic protocol (such as eigrp, ospf, etc), which can build up a map of the network to router from point a to point b. For this you also need control of the link.
    I can't think of another method, unless you can control the link from both sides. Your other option it to pool your money and buy a larger link or a leased line. If you bought a leased line or two, your carrier would be more than happy to talk to you about routing over that, but generally you're looking at mega bucks for that.

  • Weird load balancing and paging: What is going on?

    Hi,
    We have EP 7 installed in our environment.  The Portal has a Central Instance and two dialog instances.  We are using NetScaler 7 as a load balancer.  Our load balancer is currently configured with a weighted round-robin of 3:3:1.  For all requests, 3 connections are set to each of the dialog instance with only 1 connection sent to the central instance. 
    We have recently received a monitoring report which indicates that, despite the load balancing configurations, one of the dialog instance (DI1) is having a higher CPU load.  We assume this means that more requests are being sent to one particular instance.  Comparing this report with the past reports we have received, this particular instance has been consistently getting higher CPU loads, which is puzzling.  The dialog instances in our Portal setup do not do anything else, other than serving Portal requests.  In other words, no third party applications are installed on these servers.  We do not know why this particular instance is having a higher CPU load.  Is there anything that we can do to find out why this instance keeps having a higher CPU load?  Is there something we should be doing at the load balancer's end?
    On a different note, the other dialog instance (DI2) is having high paging activities.  From one of the posts in the forums, it seems to indicate that the high paging might be an indication that the Portal is undergoing some garbage collection activities.  However, it does not make sense that only ONE instance is having high paging if garbage collection is carried out on.  How is it that the rest of the instances are not having high paging issues?  Has anyone come across this situation?  What should we do to find out what is going on behind the screens?
    Any suggestions/advice would be much appreciated.
    Thank You.

    Hi Dagfinn,
    Many thanks for your reply. 
    Question1: How is NetScaler configured with regards to stickyness?
    We have NetScaler Persistence turned on, so that users' requests are served by the same dialog instance from the beginning to the end.  We found that if Persistence is not enforced, a user's request could be sent to a different dialog instance, which will cause data inconsistencies.  Can this be counted as stickyness?  I am not sure how Persistence is maintained.  It could be possible that it is done via IP...I will find out more from my colleague, who is maintaining NetScaler. 
    I guess we will need to have monitoring tools in place to determine the actual load distribution, as you have suggested in Question 2.  I guess we will have to consider the viable actions to be taken from what we shall observe... 
    Question 2: Can you get some data one how NetScaler is distributing the load in practice (not in theory, ie. configuration) ? (usually is a monitoring tool for this in such a product)
    I believe my colleague has such tools.  I will try to obtain the relevant data and make the appropriate analysis.
    Question 3: How many server nodes do you have for the central instance and for the two dialog instances?
    We have 1 server node in the central instance and 3 server nodes for each of the dialog instance.
    Many thanks again on your suggestion to choose a better score other than weighted round-robin.  We'll do the necessary analysis and decide a better score to use on NetScaler.

  • ISA570-Load balancing and Losing packets

    I am load balancing two isp's.  One isp is fine, but the other I have very high packet loss when pinging the corresponding wan interface from any machine located outside our network.  During the packet loss, I cannot https to our firewall from outside our network, but I can rdp using a different address on that same isp and ping another machine located inside our network, it seems only the wan interface is having the issues.  Our isp uses icmp to our wan interface and they started noticing the loss the other day, again the other isp loses no packets.  I have no issues with clients losing connection from that isp so it looks like it is an issue from outside in only on that wan interface.  
    I have a spare ISA and that is experiencing no packet loss when using another ip from the problem isp on it's wan interface.  The isa's have the same configuration and when I tried moving completely to the backup isa it continued with the same issue.  Upgraded to a later firmware, still the same issue.  I even took a laptop and put it on our switch that is before the isa and gave it a static public address and I can ping it with no problem from the outside.  I can also ping from the laptop to the wan port of the prod isa that is losing packets and it replies as it should, which I assumed would lose packets if it were the isa having issues, but it didn't.
    I know this has nothing to do with Cisco security services as on the backup firewall it was still losing packets when we moved the connections over to it.  
    I can ping from inside my network to the public wan address with no loss when outside machines are having problems.
    I can ping the problem wan address from a laptop or from isa(IP = 64.x.x.42) to isa(IP = 64.x.x.45) with no packet loss.  
    This is a head scratcher and I need some real help here.

    Never figured this one out.  However,  I was able to figure out how this starts. A couple of weeks ago we had an issue with an ISP and we disabled that interface during the day and re-enabled at the end of the day and thats when we noticed ICMP breaks to other ISP..  I don't know why but the ISP we renabled we can ping just fine, but the other one always has issues.  The only fix is to enable link failover detection and both WAN interfaces become pingable again.
    Now, we use load balancing and one issue we are experiencing is that randomly both WAN interfaces go down and I can confirm this with a ping utility we use off site that pings both WAN interfaces and also each ISP gateway they are connected to.  When this happens the ISP's gateways are reachable and neither WAN interface on the ISA are.  I am still on .15 version of the firmware, because there were too many issues with newer releases.  Is this a known issue?
