How to Install Second Cloud Connector Instance on one host.

Hello,

I have two hosts with AIX OS, one is QA and the other is PROD. I have already installed Cloud Connector Instances on both hosts. Now I want to install a second cloud connector Instance on the QA host to be the fail over for the PROD instance. I am logged in as root and am running in to this error:
rpm -i com.sap.scc-ui-2.11.3-6.x86_64.rpm
package com.sap.scc-ui-2.11.3-6.x86_64 is already installed.
----------------------------------------------------------------------------------
How am I supposed to install the second instance??

    Hello Syed,

    Thanks for the clarification. Unfortunately this type of configuration is not recommended since you have already the cloud connector service listening under port 8443 and this can lead to issues at OS level.

    The official recommendation is to install one instance of cloud connector per host or virtual machine, therefore If you still want to use the QA host, you have two options:

    1. Deploy a virtual machine and install the cloud connector shadow instance there.

    2. Download a portable version of the cloud connector which will allow to have multiple instances in the same host. Note that there are some restrictions. See below:

    Thanks,

    • Hello Syed,

      Please bear in mind that the portable version should not be used in productive environments, use the portable cloud connector for testing purposes only. Use the machine which runs the Cloud Connector only for this purpose and don’t reuse it for other scenarios. If you would like to have HA enabled in your landscape, this is something you need to consider prior to configure this option.

      Thanks,

      BR.

    Hi Syed Rehman But the second VM cannot be 2 things. One instance can only be either a Master or a Secondary - it cannot operate as Master for one environment and Secondary for another. You will need another VM to do this with a completely separate SCC install.

    Hello Syed,

    If you have installed the package in the QA host there is no need to install again the same package. Simply go to the master cloud connector instance administration UI and enable High Availability first, see below:

    Then you can go the shadow cloud connector instance administration UI and select Become Shadow option from the High Availability menu.

    See more information below:

    Hope this helps.

    BR.

    • Hi Carlos,
      Thank you for commenting. The issue is that the shadow instance is not yet installed. I have one PROD instance and I have one QA instance. Both are master instances. What I am being asked to do is install a 3rd instance on the same QA host and configure that as shadow for the Cloud Connector on the Prod box.

      Prod Host -- 1 Cloud Connector Instance
      QA Host -- 2 Cloud Connector Instance -- 1 instance as Master for QA & 1 instance as shadow for Prod failover.

      Let me know if that clears up my question and possible next steps.

      Again, thank you for your time.

    Agree with Carlos Delgado here - the whole point of a fail over is to have it on a separate VM/server as if you had them on the instance and that instance goes does you have lost your Master and your secondary. The recommendations as described are to have a single SCC instance on a single machine.

    • Hello Phil,

      But I do have the Master and secondary on different VMs. I have 1 VM with the Master Instance for Prod, and I have another VM that is to act as both the Master for QA and also host the failover for Prod. So if the Prod goes down, the shadow Instance will take over.
