High Availability configuration requires Master-Shadow cloud connector. While taking over, sometimes in exceptional situations, where both of cloud connector in High Availability configuration are shadow role/master role. In case such bad-configuration occurs, SCP connection will be lost and Satellite systems cannot connect to SAP cloud platform (formerly known as HANA cloud Platform)
How this can happen:
If you have not setup the cloud connector HA set up perfectly, you might end up in a situation where both of cloud connector act as Master or both act as Shadow Cloud connector.
Options to rectify:
When you configure cloud connector installation, you get the option to choose master or shadow installations. However, if you are trapped in a situation as mentioned above, you either have to reinstall both master and shadow installation, and you can choose master and shadow role while setting up the initial configuration, but you will lose all the configuration and connections set up with satellite systems. Hence, it is not recommended.
Other option:
You can change the role as per your requirement using configuration.jar file.
Prerequisites:
Procedure:
service scc_daemon stop
3. Run the below command from the directory
java -jar configurator.jar -be [master/shadow]
which role you want to assign to one of the cloud connectors.
4. Start the cloud connector
service scc_daemon start
Please check the status for confirmation. It should be started and should give you the URL to login:
