  • 1.  SDM and UIM integration over virtual ip address of SDM

    Posted Apr 02, 2018 08:47 AM

    Hi All,

     

    Am asking this on behalf of customer (I have changed the port numbers below),

     

    We have 3 application servers configured with VIP (virtual IP-address) in load balancer. we want to use the virtual IP-address of the SDM server to integrate with UIM.We have ssl configuration on the VIP and it is working on port 8443. It is doing ssl offloading and forwarding the request in plain http on port 9090.

     

    We have integrated UIM and SDM using sdgtw probe. The sdgtw probe uses soap on port 9090 and Rest on 9050.

     

    Please confirm how we can configure VIP with port 8443 and sdgtw probe on port 9050.

     

    Is the above even possible (or) should this go as an enhancement request?

    The sdgtw probe configuration should point to the VIP address and port.

    It should be transparent to the probe.

    In terms of how to configure the VIP, that depends on what type of device they are using?  Is this an F5?

    Hi Shawn,

     

    Thank you, guess it should be F5. Will ask the customer to follow the thread.

    This documentation page has the steps for configuring the F5 or CA Service Desk Manager:

    One of the issues with SDM SOAP is that we do not support replication of our authentication tokens (called SIDs).  A an SID token generated on a specific SDM server is valid only on that server.

     

    So, when you try to use any web services integration coming into SDM over a Load balanced set of SDM servers, as long as you have stringent session Stickiness, then you maybe OK.  

     

    The main issue with something like UIM (or Spectrum or Process Automation Manager) load is that, they're usually initiated from just a handful of servers. (mostly one or two servers).  So source IP based persistence will still create an un-balanced traffic because, your request would be sent to just (by F5 to) one server or the other on SDM side.  

     

    The above is something to keep in mind.  We did have some customers who submitted some ideas about full load balancing support SDM SOAP traffic  Balance of WebEngines/Domsrvrs for WebServices Applications (SOAP/REST) 

     

    Some had got around it by enabling JVMRoute based load balancing on AXIS  How does CA Service Desk do load balancing and how can sticky sessions be enabled? 

     

    Hope the above two help you a bit more.
