The polling transports (Email, File, FTP) in Service Bus only poll on one managed server for a given service, which is defined in the service configuration. However, if the polling managed server is not running, polling is not resumed automatically on another managed server in the cluster.
The zip file below contains a collection of WLST scripts meant to aid in the re-targeting of polling services from one managed server to another, such as during a managed server outage.
To redirect pollers to a new managed server, use the scripts to take the following steps:
1) List all the services currently polling on a given managed server and save this information to a file.
2) Modify all the services in the list to poll from a different managed server.
3) Once the original managed server is back on line, use the original list to modify those same services a second time to move the poller back to that managed server.
Additional usage information can be found in the enclosed readme.txt file.
