Repository Data Migration

• if the repository has never had a clean initialization, do that first Repository Clean Initialization
• the root directory (usually /home/repository) must be unique to only one server (no linking from different repository to the same location) because its indexes must match the DB contents
• BE SURE THAT THE DB SNAPSHOT HAS BEEN DONE AT THE SAME TIME AS THE DATASTORE FILES SNAPSHOT
• if tomcat is running, stop it possibly gently using the method startShutDown with admin certificate (this will finish the pending registrations and backup the statistics)
• remove and recreate the used mysql database
• import the data from the backup into that database
• copy the files matching the db backup into the datastore directory or link to the directory structure where the files are available
• if linking, be sure that the user running tomcat can read and write that location
• remove the 3 directories (not enough to remove the content, the directories must be removed) called "index" inside ./workspaces/default ./workspaces/volatile and ./workspaces/metrics
• start tomcat
• at this point the webservice notices that the index directories are missing and re-starts the indexing. It may take around 15 minutes
• verify that the logs (usually /tmp/eticsRepositoryWSLog.log) include "Repository service successfully initialized..."
