Method Detail

runMigration

public boolean runMigration(Connection windchill_database_connection,
                            PersistentObjectManager pom,
                            PrintWriter log_writer)
                     throws Throwable

Description copied from interface: Migrator

Run the migration.

Migrators should log all output to the given PrintWriter. This is the log that is created by RunMigrators. It is an autoflush writer.

Migrators should return true if they successfully completed migration and false otherwise. It is the migrator's responsibility to log failure reasons to the log.

Migrators should not concern themselves with committing the work on the connection. The MigratorRunner will commit the connection work after running each Migrator.

Specified by:

runMigration in interface Migrator

Parameters:

windchill_database_connection - an open connection to the Windchill database

pom - a persistent object manager against the Windchill database

log_writer - an autoflush printwriter for logging any and all output

Throws:

Throwable - declared so that migrators can let exceptions contibuting to failure pass out of the method. The migrator runner will handle these by logging them.
