Verifying server rename for SPARQL Gateway

This topic describes the final verification steps to take for the SPARQL Gateway component after a successful server rename and after you have completed the steps in the server rename verification wizard.

Then the server is restarted, SPARQL Gateway detects the .mappingEvent file in the conf/SPARQL_Gateway folder and starts rename process. During the server rename process, all request sent to the SPARQL Gateway will be redirected to the JTS server rename status page. Once the server rename is completed, all SPARQL Gateway function resumes automatically.

Note: For each server rename event, the previous database directory and configuration file are backed up under conf/SPARQL_Gateway folder with server-rename-event-id and timestamp appended to the file names. For example: SPARQL_Gateway.properties__bkDPUIwREeKo_aeYfgBi_A_2013-03-13_15-10-50 and db_old__bkDPUIwREeKo_aeYfgBi_A_2013-03-13_15-10-50. To reverse server rename for the SPARQL Gateway, shut down the server and rename the database directory and configuration file back to default value, for example: SPARQL_Gateway.properties and db, and restart the server.
