Resolution

Warning: This s not a standard procedure and should be carried out as a last resort to connect a client master to CJOC!

You need to purge the CJOC configuration for your Master, and recreate the client master connection from scratch following these steps:

1 [CJOC]: Release and Delete the client-master you have the issue with**

2 [Master]: Stop instance

3 [Master]: Delete the following files for the master to entirely remove the link to CJOC:

• $JENKINS_HOME/license.xml
• $JENKINS_HOME/operations-center-cloud*
• $JENKINS_HOME/operations-center-client*
• $JENKINS_HOME/com.cloudbees.opscenter.client.plugin.OperationsCenterRootAction.xml

4 [Master]: Disable Security in the Master by editing $JENKINS_HOME/config.xml. Locate this line: <useSecurity>true</useSecurity> and changing it to <useSecurity>false</useSecurity>

5 [Master]: Start the Master

6 [CJOC]: Create a new client master

7 [CJOC]: Configure the Licensing strategy that you want to use

8 [CJOC]: Connect the client master either by push configuration from CJOC or manually from the Master

9 At this stage, if the connection does not work and you are still stuck on the registration screen, you need to ask support for an evaluation license to get past the registration screen.

10 [Master]:The client master may need to be restarted to complete license registration.

11 [CJOC]- Optional: Operations center might be keeping values in cache that prevent provisioning of a new master. If this procedure did not get you past the registration screen, you may have to restart CJOC. Re-do the procedure, stop CJOC in step 2 and start CJOC in step 6.
