Load balanced router hangs

Hello,
did anybody else also experience the following problem?
Problem:
The router of a load balanced service object sometimes and all of a sudden stops forwarding incoming requests to its instances, although all instances are available and free.
This finally causes the whole application to hang, since no further call to a method of that service object is being processed.
Observations:
The dump of the load balanced router during this situation indicates that none of the instances is being used (see below). Besides, the instrument MembersInUse has a value of 0.
CPU load of the nodemgr and the router process increase significantly.
There is no DB deadlock.
We have had this problem on several different load balanced service objects (at different times; with dialog durations message or transaction).
It does not depend on overall system load or on available memory resources - the problem can occur at any time.
We can solve this lock situation by restarting the router.
UDS 5.0.3, HP-UX 11
Thanks in advance for any help or hints on what may be going on.
Martin.

Hi Mark,
thank you for your response. I talked to our network group, they told me, that there should be no scans going on. Do you have an idea how we could verify this from the application side, e.g. are there any trace flags we could enable to get some feedback?
Anyway, we did further investigations and found the following:
1) The nameservice contains references to old, non-existing partitions, even to partitions that lived before the last reboot of the system, which are not marked as "[Needs Rebind] [Rebinding]" (showpart in nameservice). By the way, the instrument DeleteOnCommFailure is set to TRUE in our environment.
2) The directory $FORTE_ROOT/tmp containing the unix domain socket files does not get cleaned up. It contains even very old entries.
3) Putting 1) and 2) together, we found out that during the hangs of our system, the load balanced router tries to send a message to one of the not-more-existing instances of the Service Object.
Example:
The following dumps were done while our system was hanging.
The router partition in question is ...:0x3ce25:0x1.
The non-existing partition of the Service Object instance is ...:0x3b913:0x2.
The non-existing process has the PID 16736 (there was such a process running a Service Object instance prior to rebooting the system).
The socket file '/forte/tmp/FORTE_A00004160' still exists.

  • 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?

    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.

  • Internet Load Balancing - Routing Issue

    Dear all, good day...
    in our ministry we are going to contract with 2 ISPs to provide us with the internet service (one of them will be the main line 16 MB, and the other line will be working as a backup line). Now, here is my question, is there any router that can holds the 2 ISPs lines at the same time and have the fail over property and load balancing, or i have to use 2 different routers (we have CISCO 2821) to do the load balancing between the 2 internet lines. Thankx

    Hi Tareq
    There are many ways you can do.But depending on your requirement.If you are using 2 ISPs and all of ISPs are willing to do BGP then that is the right way you should do. For doing load-sharing.please check this link out.
    http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a00800945bf.shtml
    Just my thought.In case one of your ISPs can't do BGP then you can use the policy-based routing feature to do out-bound load-sharing(inside to ISPs) by classifying traffics you want.
    Try to understand technology first.

  • How to Configure Multiple Portal Middle Tiers with a Load Balancing Router

    Hi,
    Portal version trying to install 10.1.2 on Windows 2003 boxes.
    I am following the guide http://download.oracle.com/docs/cd/B14099_19/portal.1012/b14037/cg_advnc.htm#i1046354. I have InfraStructure installed on a different box and am trying to install 2 Portal Midtiers each on separate boxes and using LBR. The above document is kind of confusing as I am trying to following
    5.3.1 Step 1: Install a Single Portal and Wireless Middle Tier (M1)
    5.3.2 Step 2: Configure OracleAS Portal on M1 to Be Accessed Through the LBR (AND FOLLOW ARE THE STEPS 1 to 14 in sequence)
    if I follow 1 to 14 steps in sequence the information is not consistent what is being listed in the following sections
    5.4.1 Create Virtual Hosts
    5.4.2 Configure OracleAS Web Cache
    5.4.3 Register OracleAS Portal with OracleAS Single Sign-On
    i.e.
    ptlconfig -dad portal -sso -host www.abc.com -port 7779
    ptlconfig -dad portal -sso -host www.xyz.com -port 7779
    as in the above steps it says to run
    ptlconfig -dad portal -wc -site
    and ssoreg command that always fails because I am running it from midtier as it gives error saying invalid username/password
    as oppoesed to steps listed in point 8, 9, 10, 11 and 12.
    Can someone please privide the steps in sequence I need to follow when installing 2 midtiers with frontend LBR and one infrastructure. I am trying to follow the architecture listed in the above link.
    Any help is really appreciated.
    Thanks

    Hi,
    Will appreciate any inputs on the following.
    I am planning to install Infrastructure and one Midtier BI Forms Reports Discoverer, Portal on one windows box and the second midtier BI Forms Discoverer, Portal on the second windows box.
    Please correct me if I am wrong on installing and configuring the mid-tiers as following are the steps I have compiled going through the document and want to make sure this time I do it right.
    As I'll be installing BI Forms Reports Discoverer, Portal so wondering when I install the second midtier do I need to unselect all Portal, Forms, Reports, Discoverer or just the Portal I need to unselect.
    Also in the host file of both the windows boxes do I just need to keep the LBR IP Address entry and remove the rest.
    LBR:_
    Computer Name: bigip5.prd.com
    IP Address: *167.123.2.5*
    Listen Port: *80*
    Invaidation Port: *9401*
    Infrastructure:_
    Computer Name: portal1.prd.com
    IP Address: *167.123.2.6*
    Oracle HTTP Server Listening Port: *7777*
    Application Server Control port: *1800*
    M1 (Portal & BI Forms Reports Discoverer):_
    Computer Name: portal1.prd.com
    IP Address: *167.123.2.6*
    Oracle HTTP Server Listening Port: *7778*
    OracleAS Web Cache Listening Port: *80*
    OracleAS Web Cache Invalidation Port: *9401*
    OracleAS Web Cache Administration Port: *9400*
    Web Cache Statistics port: *9402*
    Application Server Control port: *1810*
    M2 (Portal & BI Forms Reports Discoverer):_
    Computer Name: portal2.prd.com
    IP Address: *167.123.2.7*
    Oracle HTTP Server Listening Port: *7778*
    OracleAS Web Cache Listening Port: *80*
    OracleAS Web Cache Invalidation Port: *9401*
    OracleAS Web Cache Administration Port: *9400*
    Web Cache Statistics port: *9402*
    Application Server Control port: *1810*
    First to create MetadataRepository and then Install Infrastructure and then follow the below steps to install Midtiers
    Install and Configure of M1 (Portal and BI Forms Reports Discoverer):-_
    *5.3.1 Step 1*: Install a Single Portal and BI Forms Reports Discoverer (M1 i.e. portal1.prd.com)
    *5.3.2 Step 2*: Configure OracleAS Portal and BI Forms Reports Discoverer on M1 to Be Accessed Through the LBR
    *1.* Configure LBR
    *2.* Follow Section 5.4.1.1 to create the Virtual Host for bigip5.prd.com (LBR) and portal1.prd.com (M1)
    *3.* Define a site that matches the virtual host entry for bigip5.prd.com (LBR) on Webcache of M1
    *4.* Use OracleAS Web Cache Manager on M1, to map the site bigip5.prd.com (LBR) to middle tier portal1.prd.com (M1).
    Follow steps 5 and 6 as per the document
    *7.* Configure bigip5.prd.com (LBR) to accept invalidation requests from the OracleAS Metadata Repository on a separate port i.e. 9401
    *8.* Change iasconfig.xml on M1
    *9.* run ptlconfig -encrypt
    *10.* Register the URL changes with OracleAS Portal by running ptlconfig -dad portal -wc -site
    *11.* No need as it is http only
    *12.* Run the follwoing
    MID_TIER_ORACLE_HOME_M1\sso\bin\ssoreg.bat
    -site_name bigip5.prd.com
    -mod_osso_url http://bigip5.prd.com:80
    -config_mod_osso TRUE
    -oracle_home_path MID_TIER_ORACLE_HOME_M1
    -config_file MID_TIER_ORACLE_HOME_M1\Apache\Apache\conf\osso\osso.conf
    -admin_info cn=orcladmin
    -virtualhost
    *13.* Edit targets.xml to enable monitoring of the LBR's front-end host and port settings for OracleAS Portal
    +<Property NAME="PortalListeningHostPort" VALUE=http://bigip5.prd.com:80/>+ and then run
    MID_TIER_ORACLE_HOME_M1\bin\emctl reload
    *14.* Test the setup
    Install and Configure of M2 (Portal and BI Forms Reports Discoverer):-_
    *5.3.4 Step 4*: Install a Single Portal and BI Forms Reports Discoverer (M2 i.e. portal2.prd.com)
    *1.* As I am installing on wiondows so will not set IASCONFIG_LOC environment variable as I can just copy the iasconfig.xml file from M1 to M2
    *2.* Run OUI on M2
    *3.* Clear the selection for OracleAS Portal but don't know if I need to unselect Forms , Reports, Discoverer also.
    *4.* Enable OracleAS Portal
    *5.3.5 Step 5:* Configure the New Middle Tier (M2) to Run Your Existing Portal
    *1.* Create both virtual hosts as done on M1
    *2.* Copy dads.conf, oradav.conf, cache.conf, web.xml from M1 to M2
    *3.* Re-register mod_osso on M2. To do this, perform the following steps by copying osso.conf from M1 to M2
    *4.* Synchronize the DCM by using the following command
    MID_TIER_ORACLE_HOME_M2/Apache/Apache/bin/ssotransfer MID_TIER_ORACLE_HOME_M2/Apache/Apache/conf/osso/osso.conf
    *5.* Run dcmctl updateConfig
    *6.* add the necessary mod_rewrite and mod_oc4j directives to the httpd.conf and mod_oc4j.conf files respectively
    *7.* Restart Oracle HTTP Server on M2
    *8.* Access the OracleAS Web Cache Manager on M1 and follow steps 9,10,11,12,13,14,15,16 for Webcache seetings and clustering.
    Also will appreciate if can get some info on the following:
    *1.*
    When I configure the Webcache as per the Document but if I bring down one Midtier Instance the requests are not going to the other Instance that is up and ignores the case whether an instance is down. Any idea how what and where do I need to provide any setting which in case of instance is down routes the requests to the one that is up.
    *2.*
    What exactly happens when it says To enable monitoring of the LBR's front-end host and port settings for OracleAS Portal edit target.xml. Is this for LBR to find if an Instance is down or not and route the requests appropriately.
    Thanks again for all the help.

  • Load Balancing b/w two cisco router

    Hello Friends,
    Please advise me,We are using two Cisco Routers with F5 Load balancer,
    Router A (Cisco 2811) has one ISP configured
    Router B (Cisco 3825) has the other ISP configured
    ISP on Router A has 5 Mbps Bandwidth
    ISP on Router B has 10 Mbps Bandwidth
    My Doubt is if the load balancer is down,how to utilize the ISP (or) How to divert the connection ?
    Here i have attached my N/w diagram for ur reference..........
    Can someone solve my question.............please
    Thank you.

    Hi Mohamed,
    With default routing in use you can just configure one default route on each router   But it would only do load sharing not load balancing.
    PFR(performance routing) is a better solution but have never tried with two diffferent router series. Also need to validate if the router series you are using supports PFR.

  • Using a DI-LB604 load balancing on mac

    In my office we are using a DI-LB604 load balancing router, since the day they instaled it my internet conecction is not stable, and it works fine for all PCs in the office, i´m the only one ussing Mac

    You can take a look at this thread:
    http://forums.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=Getting%20Started%20with%20Wireless&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.2cbfa834
    But like I said, if you require more bandwidth per link you need to look at another vendor.

  • Question on how does load balancing work on Firewall Services Module (FWSM)

    Hi everyone,
    I have a question about the algorithm of load balancing on Firewall Services Module (FWSM).
    I understand that the FWSM supports up to three equal cost routes on the same interface for load balancing.
    Please see a lower simple figure.
    outside inside
    --- L3 SW --+
    |
    MHSRP +--- FWSM ----
    |
    --- L3 SW --+
    I am going to configure the following default routes on FWSM point to each MHSRP VIP (192.168.13.29 and 192.168.13.30) for load balancing.
    route outside_1 0.0.0.0 0.0.0.0 192.168.13.29 1
    route outside_1 0.0.0.0 0.0.0.0 192.168.13.30 1　　　　　　
    However I don't know how load balancing work on FWSM.
    On FWSM, load balancing work based on
    Per-Destination ?
    Per-Source ?
    Per-Packet ?
    or
    Other criteria ?
    Your information would be greatly appreciated.
    Best Regards,

    Configuring "tunnel default gateway' on the concentrator allowed traffic to flow as desired through the FWSM.
    FWSM is not capable of performing policy based routing, the additional static routes for the VPN load balancing caused half of the packets to be lost. As a result, it appears that the VPN concentrators will not be able to load balance.

  • Dual Nic Load Balancing Solution

    Hi,
    I have a very peculiar situation. I'm currently a college student with access to an almost unlimited network. But the problem is that the network limits each IP to 30 Mb/s. I have 2 nics at my disposal and have tried two options so far:
    bonding
    two independent nic, let network manager take care of it
    I set-up bonding and got it working, but it seems limited to roughly the same speeds as a single nic, but I can see the network being slit between the two nics evenly. This is what lead me to conclude that since I have a single ip address it's limiting it by IP not mac addresses. Here I might occasionally spike above the limits but not consistently.
    With the network manager solution, Im basically thrown at random and can occasionally get higher than limited speeds. Specially with torrenting clients.
    Are there any other useful options that I could explore, my next stop was a load balancing routing table but I want to see what you guys know before I keep trying weirder solutions.
    Thanks in advance

    falconindy wrote:There's no problem here. Please don't try to circumvent the policies your network admins are defining.
    Oh come on, we'd all do the same thing if we could double our available bandwidth! 
    I really can't provide much of a solution.  I did this back with my dialup days, many many eons ago.  I used 2 phone lines bonded to get my 56k speeds doubled.  It was a gigantic pain in the rear to set up back then, as well.  However, I'm lucky to remember what I had for breakfast, so remembering how I did something 15+ years ago is pretty much out of the question.
    I'm sure linux can do this, but I'm guessing one of the BSDs would have information about how to do this written up somewhere.  This is right up BSD's alley.  They have all kinds of load-balancing code built into their network stack (Amazon actually had a lot of trouble keeping up with demand when they were getting big, so they wrote up their own networking stack, which has since been returned to the FreeBSD project, iirc).  So it might be worth your time to check that out and possibly run a mini BSD setup on an old computer or something to route the bandwidth to an internal network (of course this would likely require three NICs in a single computer...so more complexity there too).  Some of the problem you are running into may be due to the network just being congested, which could explain the differing speeds.  Then there may be an issue with certain servers not being able to push out 60 MB/s worth of data to you, for whatever reason. 
    Either way, please keep us posted about what you do and how you do it, I'm anxious to find out the final solution here.
    Best of luck to you.

  • Session Binding on Web Cache acting as load balancer

    Hi gurus,
    I have Web Cache 10.1.2 acting as load balancer on the front-end machine, and two OracleAS 10.1.2 enterprise edition installations behind it. The load balancing configuration is done and is working well. The Web Cache (acting as load balancer) routes requests the to the two OracleAS installations very well.
    Now I need to set up session binding, so that a request from the same client is directed to the same OracleAS installation (in the same session). I am really a novice on session binding - could you pl let me know what I need to do?
    Going through the Web cache admin guide, I did try to use JSESSIONID but without much success. Specific Qs:
    1. Do I need to enable session binding at only the back-end OracleAS installations, or also at the front-end Web Cache (acting as load balancer).
    2. If I use JSESSIONID - is it generated by Web Cache / HTTP Server automatically, or do I need to write a J2EE application to generate it?
    Thanks a lot in advance.

    hi,,,
    i neesd some help in ur issue,
    i face a problem woth web cache in Load balancing ,, it is not working...
    my case is same to ur case, BUT i have AS10g ( 9.0.4 )
    and i got this err
    "FRM-92101: There was a failure in the forms server during startup.
    This could happen due to invalid configuration.
    Please look in the web-server log file for details."
    i followed metalink notes and configration. and Configuring Oracle HTTP Server by modifying the httpd.conf file.
    - CookieTracking On
    - and CookieName xxxxxxx
    and still the same prob ...
    could u help me plz.
    and is it because my AS version which is 10g(9.0.4) ?

  • Load balancing weirdness using NAT and same-metric route

    Hi.
    I'm trying to set up a double-WAN load-balancing scenario:
    I decided to attempt the "multiple same-metric routes with NAT" approach so I went for the example used in the IOS NAT Load-Balancing for Two ISP Connections Configuration Guide [1].
    I decided to use an upside-down Cisco 871-SEC/K9: use Vlan1 and Vlan2 for the routers and Fa4 for the LAN. I am hoping this is not an issue.
    There is this weirdness with some connections, particularly FTP. I pinpointed the problem to the following scenario: if I do a couple of pings to 100.1.1.1 using the FastEthernet4 as the source address, this is what I get in the logs:
    === PING 1 ECHO REQUEST ===

    In the section "Ping 2 Echo Request" line 2 shows the NAT translating the packet to the address for the first provider but line 3 shows it routing it through the second one.
    In this case, the ICMP packet goes through but it is problematic if the ISP restricts the service by source-address (like RPF) or there is some acceleration mechanism inside the provider cloud, other than just plain routing.
    What am I missing? Here is the relevant part of the configuration. I deliberately disabled CEF to be able to debug the messages, but I *think* this may be altering the actual router behavior. This router does not have a "debug ip cef packet" command.

    Hello.
    This might be a bug in debug command or the IOS (without ip cef) you use; as routing is done before NAT (inside to outside).
    To make sure it works fine with ip cef, just enable strict uRPF (or just ACL) on .1 and .33 interfaces and see if you see any packet sent over wrong interface.
    PS: please check "sh ip cef 100.1.1.1"; I guess ip cef would tell you "per-destination sharing".

  • Load Balancing on 837 router

    HI Prof,
    I've two cisco 837 router with cisco IOS 12.3 currently. I would like to configure load balancing on both the router, have tried to configure GLBP but it show me that the hardware not supported.
    Is there any other protocol or technology to achieve my desire?
    Thank and Advice.

    What are your requirements. Do you have multiple segments to support? Are you only looking for load-balancing or do you have a high availibility requirement?
    In that case you can use multiple HSRP groups for instance.
    Do both 837 routers have a separate xDSL connection?
    Are you using NAT to translate between private and public address pools?
    There is more than one solution to achieve load-balancing. Please answer the above questions and if possible draw a simple diagram of your desired topology.

  • 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.
    HTH,
    Mark

  • Load balancing using multiple default routes

    Hi Guys,
    I just want to ask does creating multiple default routes on my router provides load-balancing on my WAN side? As far as i know, for example if I have two default routes on my router and let say I have two users connecting to the internet, the first one might go to the first WAN link while the second user might go to the second WAN link.
    Thank you so much
    Rex

    there are the difference between, load balancing and load sharing..which we need to understand.
    load sharing means you have 2 users, user A and User B, user A wants to use ISP1 and user B wants to use ISP2. this is called load sharing. and can be achieved via PBR (Policy based routing).
    we should not try to use load balancing for Internet traffic with 2 different ISPs.

  • Load balancing with use of router 881.

    Hello,
    I have two MPLS line and i want load balancing with the help of CISCO router 881. is it necessary that i require two router on both location.? if one location have firewall and one location have cisco router 881 then can i do a load balancing or i require two router each on both location ? What are the basic requirement that i need.

    An 881 should be able to load share across multiple ports.  Many routing protocol support ECMP, including BGP, but you need "special" hidden/secret commands to enable.  EIGRP also supports unequal cost load sharing.
    If an 881 supports OER or PfR, those too will do unequal load sharing, dynamically.
