Using the cccoreservice command
The cccoreservice command is a command-line utility for managing the collage-core service on one or two Collage control nodes. It went through a pretty major overhaul back in Collage 3.4, so I thought I'd highlight how it now works.
| cccoreservice command options | On single control node... | On dual-control nodes... |
|---|---|---|
| start | Starts the collage-core service on the control node. | Makes sure the clumanager software is running and then enables the collage-core service, which will be started on either of the control nodes. |
| stop | Stops the collage-core service on the control node. | Disables the collage-core service in clumanager, which will stop the service from running on any control node. |
| restart | Stops and then then restarts the collage-core service. | Directs clumanager to restart the collage-core service on the control node on which it is currently running. |
| status | Prints the status of collage-core services on this control
node. |
Prints the status of the cluster. If the collage-core service is not running on this control node, then the status option will not provide status of the collage-core service, just the cluster software. |
| failover | Ignored. | Cause the collage-core service to be migrated to the other control node. |
As you might notice, there is some reliance on the underlying clumanager software for dual-control node configurations. To learn more, check out the article, Understanding Control Node Failover.
