How do I stop the default topology sync in Hierarchical SAM?
How do I stop Smarts SAM automatic topology synchronization in the presentation layer of a Hierarchical SAM configuration?
How do I disable automatic topology synchronization in the presentation layer of Smarts SAM?
The following sections of this Fix statement explain how to:
- Stop the automatic Smarts SAM Topology Synchronization
- Schedule a Topology Synchronization
- Find the appropriate driver
- Start the Topology Synchronization
Stopping automatic Topology Synchronization
To stop automatic Topology Synchronization in the presentation layer SAM, add the following line to the dxa-sam.conf file in the Presentation SAM server. It is necessary to restart the SAM domain after making this change to apply this change to the active system:
topoUpdate ICF_TopologyManager::ICF-TopologyManager::fakeAttr
Scheduling a Topology Synchronization
The synchronization between individual presentation and aggregation servers can be scheduled by using cron to run dmctl commands to kick off the Topology Synchronization.
Finding the driver to run the Topology Synchronization
To find the appropriate driver to run the Topology Synchronization, run the dmctl getInstances GA_DaemonDriver command and locate the entry that starts with the domain name and ends with _Topo-Driver. For example, if the SAM domain is named SAM-AGG, the driver name would be SAM-AGG_Topo-Driver. The full syntax for the required command is:
dmctl s <Presentation_SAMDOMAIN> getInstances GA_DaemonDriver
Starting the Topology Synchronization
To start the Topology Synchronization, invoke the start operation of the GA_DaemonDriver object with a command similar to the below example:
dmctl -s INCHARGE-SA invoke GA_DaemonDriver::SAM-AGG_Topo-Driver start
