Tuning Topology Split Manager discovery

After copying the discovery configurations from one of the IP Availability Manager installations to the Topology Split Manager installation, you should consider modifying certain configurations in the discovery.conf and tpmgr-param.conf files to reduce memory usage and to shorten the discovery time of the Topology Split Manager. If neither high memory usage nor long discovery time is an issue in your deployment, you can ignore the following considerations.

Consider doing the following to reduce memory usage and to shorten discovery time:

• Increase the number of discovery threads in discovery.conf Increase the number of discovery threads in discovery.conf

• Disable unnecessary discovery probes in discovery.conf Disable unnecessary discovery probes in discovery.conf

• Ensure that unnecessary discovery probes are disabled in tpmgr-param.conf Ensure that unnecessary discovery probes are disabled in tpmgr-param.conf

  Also, consider adding the --nodx option to the Topology Split Manager service command, to reduce Topology Split Manager memory use by preventing the loading of the libraries that enable codebook correlation and event generation. If necessary, use property subscription to subscribe to DiscoveryError events for UnitaryComputerSystem elements.

  If memory usage is not an issue, do not add the --nodx option to the Topology Split Manager service command.
