ICM/IPCC Enterprise: Load Balancing between 2 IVRs using System PG

Hi,
I have a question and I am not able to see the solution. I have 2 IVR type 9 configured into a System PG with two IVR pims. The problem is that when I perform a call, the call always goes to IVR number 2 and if I stop this IVR, the system doesn't work. I have verified that all is well configured, but I don't where the problem resides.
Any ideas?
Regards

Thank you for your answers.
David, I have verified that both PIMs are active.
Dchumbley, I have execute rttest status and this is the response:

I have tested the following scenario:
If I have configured the network VRU with a label from the first IVR, the call arrives to first IVR, but if I configure 2 labels for both IVRs, the call always arrives the second IVR.
Any ideas?

  • Load balancing between application server and database

    Hi,
    is there any load balancing between the application server and the database? Consider we have a single instance of an application server that sends database queries from different clients to the database. Are the requests queued in some way at the application server, allowing to control the flow of the queries (e.g. queries from "more important" clients might be sent with a higher priority)?
    Thanks for your help!

    Hi Victor/Jim/Volker,
    Thanks a lot for all the responses..
    Just wanted to let you guys know that my installation finished successfully.
    The thing which confused me was that my Qtime, Qdate and everything else was showing correct values..
    Well, my problem I set the environmental variable PASE_TZ to the EST time zone on a SYS level using WRKENVVAR>F4>SYS and added the variable. I logged off and the sidofr logged off, but one user which should have logged off and didn't was the "SAPINST"(my installation user) which was logged in the subsystem TMKSVR00.
    Even when I had closed the SAPINST installlation program, the user doesn't log off...it just sits there until and unless u shut him out of the system using the option 4 on wrkactjob for ending the JOB(SAPINST logged in the system below the TMKSVR00 subsystem)
    So since the SAPISNT user never logged of, his environmental variables were not initilized properly, even after the changes...
    This thought came to me almost after a 6 hours of wasting my time searching for notes here and there...
    I think when u end/stop the install in SAPINST, the SAPINST user should log off the AS400 system, but I have noticed, it never does...although when u restart the installation, if u have noticed it shows you the log on for the SAPINST user in the TMKSVR screen...
    Its kind of buggy, I would say...
    I have noticed, that even when I log on to AS400 from home or from a remote PC using Emulator, it shows me logged in the subsystem and even after i have logged of, it still shows me there...
    Anyway, thanks a lot guys...for all your responses..
    Just wanted to let you know all.
    Thanks

  • Load balancing between two routers

    I have two routers connected through the LAN connection. The first one is using as routing protocol EIGRP, the other one is part of the managed service and I do not have access to it. I would like to make a load balancing between the two of them by redistributing the static routes in EIGRP. When I tried this, I am loosing the EIGRP entry for this route in the routing table. I would like to have both of them , so we could have traffic sharing. I appreciate if you give me any hints.

    Raju,
    you have two choices as far as I can see. If you want to use static routing over the WAN to your branch, you could duplicate your static routes to the branch and point them to the secondary router. You will have two identical sets of static routes in the primary router, one set pointing to the WAN interface and the other one pointing to the secondary router.
    ip route x.x.x.x "WAN-interface"
    ip route x.x.x.x "secondary router"
    ip route y.y.y.y "WAN-interface"
    ip route y.y.y.y "secondary router"
    etc.
    As a result the primary router will have two routes to the branch and will load-balance. If one next-hop fails (either the WAN interface or the secondary router), only the other will be used. If the next-hop comes back up, load-balancing will resume.
    The other choice would be to use EIGRP over the WAN, and make sure the two routers become EIGRP neighbors. Then you can use the "variance" command to achieve unequal cost load-balancing between the two routers. Let me know if you need more information about this, but i think static routes will be sufficient in your situation.

  • Load balancing between Instance for same external IP client

    Hi,
    I have a azure website which is single tenant and is going to be used inside a single Domain from same region.
    Now my website provide good  performance till 20 concurrent request. I want to scale this so that it can reach up to 30 - 40 -100 so on.
    What are the options available to achieve this. till now what i have figured out is that
    1. If i increase the web site instance or on the auto scale option. It load balances between the instances on the basis of Client external I.P. but in my case all the users which are using the site shares the same external IP. 
    I have tested it increasing the instances doesn't make any impact on my performance results. 
    2. I have also looked in traffic manager but that case is valid when the clients are on different GeoLocations which is also not valid in my case.
    So my basic Question is if i have a pool of different scenarios where 
    100 users uses 1 azure website
    200 uses uses 1 azure website
    1000 users uses 1 azure website
    what infra should i take for each website to support this have performnace same as 100 users.

    Hi,
    I would request you to configure Web hosting plan and check if it helps in increasing the performance.
    It gives a set of features and capacity that you can share across your websites separately.

  • Round robin DNS for load balancing between multiple network adapters (Xserve)

    I'm attempting to use 'round robin' DNS to load balance between the two ethernet adapters of an Xserve.
    Both ethernet adapters are connected to the same LAN and have static IP addresses of 192.168.2.250 and 192.168.2.251.
    The DNS zone for the server's local domain/host (macserver.private) has a machine record with both IP addresses (set up in the Lion Server UI).
    Having read up on round robin DNS, I would have expected DNS requests for 'macserver.private' to be answered with the two IP addresses ordered at random, achiving my aim of requests being served at random via each ethernet adapter.
    However this doesn't seem to be the case. Doing a 'nslookup' from any of the network clients results in the two IP addresses being listed in the same order everytime. And pinging 'macserver.private' only ever results in a response from the same address.
    Does anyone know why this is the case? Does Lion Server use a non-standard DNS configuration? Are there any additional settings I need to configure in Lion's DNS server to make adopt a round robin approach to responding to requests?
    Thanks in advance for any help!

    Be careful what you wish for
    Round Robin DNS is rarely the best option for 'load balancing'. At the very least it's subject to caching at various point on the network - even at the client side, once the client looks up the address it will cache that response - this means that subsequent lookups may be served from the client's cache and not refer back to the server. Therfore any given client will always see the same address until the cache expires.
    I suspect this is what you're seeing.
    You can minimize this by setting a lower TTL on the records. This should result in the response being cached for a shorter period, meaning the client will make more requests to the server, with a higher change of using the 'other' address.
    However, you're also going to run into issues with the server having two interfaces/addresses in the same LAN. This isn't recommended.
    As Jonathon mentioned, you may be better off just bonding the two interfaces. This will provide an automatic level of dynamic load balancing without the latency of DNS caches, as well as automatic failover should one link fail (as opposed to round robin DNS which will cause 50% of requests to fail until the client cache expires and a new lookup is performed (and, even then, there's still a chance the client will try to use the failed link).

  • Question about load balancing between Portal and ABAP

    Hi,
    I have the problem whit load balancing between Portal and ECC (ERC) ABAP
    Exist two system:
    1) ECC (ERP) ABAP = Backend     Module = HR
    2) EP (JAVA) = Frontend
    The users (9000 users) logon in the EP and run query (data personal) in the ECC.  The problem to all user connect in Central Instance and not in the Dialog Instance.
    How can balancing the conecction HTTP (EP) to ECC (ABAP)??
    I need balancing in the ECC to Dialog Instance

    Jco -> right. Another possibility is that you use iviews that point to the backend in this case you will need to use a load balanced entry for the backend system in the [system landscape|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/8c1e438d7017fce10000000a42189c/frameset.htm] -> SAP_R3_LoadBalancing
    If you have ESS deployed on your portal, you will most probably need to do both.

  • Load-Balancing between Foreign and two Anchors

    Hi, we have two foreign controllers (one active, one standby) and two anchor controllers. All APs are connected to the active foreign controller. The layer 3 networks for the wlan clients on both anchors are different for the same SSID. SSID: Internet, anchor 1: Subnet A, anchor 2: Subnet B. So when a client is getting anchored to Anchor 1, the clients will get an ip from subnet A and when the client is getting anchored to anchor 2, the client will get an ip from subnet B.
    This is so far not a big problem because we only have a few accesspoints in some rooms. But what will happen, when we have a full covered wlan and the client roams from one AP to the other AP? Is there a possibility, that the client will anchored to a different anchor while roaming? I think this will result in a lack of connectivity because without a real disconnect the client will not ask for a new IP address.
    Other question: Is it possible to disable this load-balancing between anchor controllers? Or can i make a client sticky to only one anchor as long as an access-session is established?
    All controllers are 5760 with 3.3.3 software.

    Hi acontes, 
    It's an interesting question. 
    In this case, if all AP's are on WLC-A and there is no possibility that an L3 inter-subnet roam will occur between WLC-A and WLC-B, I would just forward WLC-A to Anchor A and WLC-B (in the event of fail over) to Anchor B (if Anchors reside on different subnets). If you must specify Anchor A and Anchor B on each WLC for redundancy purposes, it's important to understand the guidelines and limitations with regard to Foreign / Anchor Design.  
    As Scott mentioned, the limitation with Anchoring design is that there is no primary / secondary configuration for an Anchor on the Foreign WLC.
    If WLC-A has two entries (1) for Anchor-A and (2) for Anchor-B, the EoIP tunnels are establish and load-balancing occurs in a round robin fashion.
    Keep in mind the following with regard to guest N+1 redundancy:
    •A given foreign controller load balances wireless client connections across the list of anchor controllers configured for the guest WLAN. There is currently no method to designate one anchor as primary with one or more secondary anchors.
    •Wireless clients that are associated with an anchor WLC that becomes unreachable are re-associated with another anchor defined for the WLAN. When this happens, assuming web authentication is being used, the client is redirected to the web portal authentication page and required to re-submit their credentials.
    Since traffic is transported at Layer 2 via EoIP, the first point at which DHCP services can be implemented is either locally on the anchor controller or the controller can relay client DHCP requests to an external server. Since the IP address directly correlates to the DMZ subnet or the interface where the traffic egresses, it is possible for some clients to get IP's from both Subnet A or Subnet B in the event that WLC-A is building EoIP to both anchors.
    1) What happens if my clients roam?
    Nothing... since all AP's are on WLC-A, it's Intra-Controller Roaming
    Each controller supports same-controller client roaming across access points managed by the same controller. This roaming is transparent to the client as the session is sustained, and the client continues using the same DHCP-assigned or client-assigned IP address. The controller provides DHCP functionality with a relay function. Same-controller roaming is supported in single-controller deployments and in multiple-controller deployments.
    Would it be better to choose the same DHCP Pool on both anchors?
    It's probably better to have redundant anchors on the same subnet, but it's not required. 
    3) How would you design this :-)
    WLC-A <--EoIP--> Anchor A (DHCP Pool A)
    WLC-A <--EoIP--> Anchor B (DHCP Pool A)
    It's important to remeber what Scott mentioned about the lack of a primary / secondary relationship. If multiple controllers are added as mobility anchors for a particular WLAN on a foreign controller, the foreign controller internally sorts the controller by their IP address. The controller with the lowest IP address is the first anchor. For example, a typical ordered list would be 172.16.7.25, and 172.16.7.28. If the first client associates to the foreign controller's anchored WLAN, the client database entry is sent to the first anchor controller in the list, the second client is sent to the second controller in the list, and so on, until the end of the anchor list is reached. The process is repeated starting with the first anchor controller.
    If any of the anchor controller is detected to be down, all the clients anchored to the controller are deauthenticated, and the clients then go through the authentication/anchoring process again in a round-robin manner with the remaining controller in the anchor list. This functionality is also extended to regular mobility clients through mobility failover. This feature enables mobility group members to detect failed members and reroute clients.

  • Enterprise Load Balancer

          Dear Team,

    You have to remember that the 9.0.4 release isn't that new either. However, you can basically use every load balancer out there if they support 1) Sticky/Persistent sessions and 2) Nat client.

  • Distributed Queue - Unable To Load Balance Between Each Time A Send Method Is Called

    Hi,
              According to the JMS documentation, I should be able to get the
              distributed queue to load balance
              between each time the message producer calls Message.send(). I was not
              able to achieve this, however,
              I noticed the load balancing happens when a JMS client is stopped and
              restarted (meaning totally
              exit the JVM and restart the JVM).
              Here is my configuration:
              WLS 8.1 SP2 on XP
              One cluster with two nodes (running on the same machine w/ different port)
              Each node hosts one JMS server, which hosts one physical queue and using
              JDBC store
              One distributed queue with two physical members from each of the JMS
              server.
              JMS Connection Factory is configured with "Load Balancing Enabled" set to
              yes,
              and "Server Affinity Enabled" to no. This connection factory is target to
              the cluster.
              The queue session for the queue sender is created with transaction setting
              to false.
              Any hints and ideas would greatly appreciated.

  • How to properly load balance between diffrent server farms.

    Hi experts,
    We are using an ACE 4710. We chose for our server farms to load balance using the least_connections predictor. it seems to work fine inside the same server farm but is it working properly between server farms? It doesn't seem because some of my real servers seems to be more loaded than others. Each server farm are using the same real servers.
    Any idea about what is the problem or any suggestion regarding the best load balancing predictor we should use using this kind of configuration?
    Thank's to all.

    The ACE uses load-balancing algorithms or predictors to determine how to balance the traffic among the devices configured in the server farms, independent of the device type. For FWLB, we recommend that you use only the hash address source and the hash address destination predictors. Using any other predictor with FWLB may fail and block traffic, especially for applications that have separate control and data channels.
    Here is the configuration guide for the Cisco ACE 4700 Series Appliance Server Load-Balancing.

  • Load balancing between two interfaces on 2811

    Hi,
    We have a 2811 router with VPN and NAT configured. We have two internet connection from different ISPs. The speed of our original connection is 2MB up and down. The speed of our new connection is 1MB up and down. We want to configure load balancing between the two connections. Our new ISP has provided us with a CISCO 837 router. We want to connect that router into our 2811 on one of the free WIC card and then configure load balancing between the two interfaces on our 2811. The third interface has a local address configured. Please suggest where to start. I tried searching on net for any configuration example but I was unable to find any particular example with commands. I am new on CISCO platform. Any help will be hugely appreciated. Thanks in advance.

    Raju,
    you have two choices as far as I can see. If you want to use static routing over the WAN to your branch, you could duplicate your static routes to the branch and point them to the secondary router. You will have two identical sets of static routes in the primary router, one set pointing to the WAN interface and the other one pointing to the secondary router.
    ip route x.x.x.x "WAN-interface"
    ip route x.x.x.x "secondary router"
    ip route y.y.y.y "WAN-interface"
    ip route y.y.y.y "secondary router"
    etc.
    As a result the primary router will have two routes to the branch and will load-balance. If one next-hop fails (either the WAN interface or the secondary router), only the other will be used. If the next-hop comes back up, load-balancing will resume.
    The other choice would be to use EIGRP over the WAN, and make sure the two routers become EIGRP neighbors. Then you can use the "variance" command to achieve unequal cost load-balancing between the two routers. Let me know if you need more information about this, but i think static routes will be sufficient in your situation.

  • 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!

  • Question about Load Balance SFTP service by using CSS1150X

    Does anyone come across of load balancing SFTP service by using CSS1150X? Typically by configuring CSS1150X to load balance FTP service, the configuration will as follow:
    content ftp_rule
    vip address 192.168.3.6
    protocol tcp
    port 21
    application ftp-control
    add service serv1
    add service serv2
    add service serv3
    active
    group ftp_group
    vip address 192.168.3.6
    add service serv1
    add service serv2
    add service serv3
    active
    However, for my personal understanding and knowledge, I will configure my CSS1150X as follow to load balance SFTP service:
    content sftp_rule
    vip address 192.168.3.6
    protocol tcp
    port 22 //Change 21 to 22
    application ftp-control
    add service serv1
    add service serv2
    add service serv3
    active
    group sftp_group
    vip address 192.168.3.6
    add service serv1
    add service serv2
    add service serv3
    active
    My question is, "application ftp-control" in content "ftp_rule" is still applicable to SFTP or not?

    I believe application ftp-control would not be used for sftp.
    This might cause the session to get dropped when there is no data channel created and cause issues with long connections.
    Hope it helps!!

  • Lync 2013 Enterprise load balancing on the front end and edge pool

    Hi,
    I am setting up a Lync 2013 Enterprise deployment consisting of a Front End pool (x2 FE servers) and an Edge pool (x2 Edge servers).  I'm seeing some conflicting advice regarding load balancing using hardware or DNS for the front end and the edge.
    On the front end I have 2 internal DNS records 'lyncfepool1.contoso.local' each of which map to one of the IPs of the FE servers.  I've used my details to populate the Detailed Design Planner excel spreadsheet and am told that I require a HLB to load
    balance my front end pool.  I'm aware of the need to load balance HTTPS traffic internally (which will be done by TMG) however other traffic to the front end (SIP, etc) can be balanced by DNS only, and not require a HLB?
    Can someone clarify the front end requirement?
    Also - looking now at the edge pool - this site again have two edge servers in a pool.  We are using a total of six private IP addresses, two per edge service (2 x av.contoso.com, 2 x sip.contoso.com and 2 x webcon.contoso.com).  These will be
    NAT'ed by the external firewall and directed to the respective external (DMZ) IP addresses on the Edge servers on port 443.  I know this isn't true roundrobin due to the intelligence of the Lync client when connecting (in that the Lync client will connect
    to one of the public IPs and if it can't connect, it will know to connect to the other service IP), however I want to clarify this set up, particularly the need to direct the external public IP traffic at the DMZ Edge IP specified in the topology builder.
    I've attached a basic diagram of the external/DMZ/Edge side which hopefully helps with this question
    Persevere, Persevere, Per..

    That is because you will always need HLB for a front-end server since it hosts the Lync webservices which use HTTP/HTTPS traffic.
    The description on the calculation tool also describes this correctly:
    Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing or a combination of DNS load balancing and device-based load balancing (for
    Lync web services)
    You can use either Hardware or DNS loadbalancing for SIP traffic only, but you will always need a HLB for the webservices.  Both are applicable for the Front-End so you have either
    full HLB for both SIP and HTTP(S) traffic
    DNS LB for SIP traffic and HLB for HTTP(S) traffic
    Hope this is more clear :-)

  • Load Balance Between Diff DB's or Instances??

    Hello All,
    Based on the below TNS entry, my understanding is that since it has multiple listener addresses by default connect time failover is configured and as description says load balancing option is also enabled.
    But how would i know whether fail over & load balancing is happening to the same instance of database or altogether to a different database??.... I did nslookup on the server names though IP addresses are different it's still not clear for me....
    How different are the Oracle instance & Oracle DB??
    Could you please shed some light for me to cross check, Thank you.
    BDCD =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = xxx-vip.abc.com)(PORT = 1557))
        (ADDRESS = (PROTOCOL = TCP)(HOST = yyy-vip.abc.com)(PORT = 1557))
        (LOAD_BALANCE = yes)
        (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME = BDCD)
      )

    1.) Thanks for your reply, so load balancing and/or fail over will only happen between different instances of the single database or can it also be possible between 2 different databases provided the databases are in sync??
    Yes, it can be done between two databases as well and this is called Standby database configuration. This won't do the load balancing for you but you would get teh switchover (or Failover) between two.
    2.) Would it be possible to have PROD & DR database servers with load/fail over options configured and also with dataguard setup between those 2 DB's will have same IP addresses & host names like below?
    PROD      DataBase Server     tsjipud186.xyz.mq.abcd.net     123.45.67.30
                         tsjipud187.xyz.mq.abcd.net     123.45.67.55
    DR     DataBase Server          tsjipud186.xyz.mq.abcd.net     123.45.67.30
                        tsjipud187.xyz.mq.abcd.net     123.45.67.55
    Hmm may be I need a cup of coffee because not able to parse the question.
