Admin: Working with Roles

Taking a Node Offline

When a node is taken offline, all roles at the node are taken offline.

Putting a Node Online 

• When a node is put online, all roles at node are put online.

• When a node is offline, putting one of its roles online puts the node as a whole online.

• If all of a node’s roles are put offline, the node itself becomes offline.

Taking a Node Manager Role Offline

When a Node manager role is taken offline and it is the master node, another node in the cluster assumes the Master node status.

Putting a Node Manager Role Online

When a Node manager role is put online, it is available to assume the status of master node.

Taking a Windows Services Role Offline

• When a Windows services role is taken offline, the role is no longer able to have server jobs assigned to it.  Any server jobs owned by the node in question with an InProgressAtHost status remain as such.

• At RPI, any Playing workflows controlled by the node are Paused.  Playing and Waiting for Trigger activities within workflows are Paused.

• An attempt to Play a Paused workflow owned by the node causes it to enter a Resume Play Requested state; invoking Stop in the same scenario causes the workflow to enter a Stop Requested state.

• If a scheduled or recurring trigger fires while its owning node is offline, it enters a Play Requested state.  If a scheduled wait for event fires in the same context, it enters a Paused state.

Putting a Windows Services Role Online

When a Windows services role is put online, it is once again available to accept server jobs.  Any InProgressAtHost jobs re-commence execution.

At RPI, any automatically-Paused workflows and the activities they contain are resumed.

Taking a Web Services Role Offline

• Load balancing of web service roles is typically handled by IIS and is outside the scope of this documentation.

• When all of a cluster’s web services roles are taken offline, users will no longer be able to log into RPI, and users logged into the RPI client application will be unable to communicate with the server.

Putting a Web Services Role Online

At least one web services role must be online in order for users to log into RPI.

Taking a Help Files Role Offline

• Load balancing of help files roles is typically handled by IIS and is outside the scope of this documentation.

• When all of a cluster’s help files roles are taken offline, users will no longer be able to view RPI help.

Putting a Help Files Role Online

At least one help files role must be online in order for users to view RPI help.
