Class DatabaseIdentity

java.lang.Object

ome.services.db.DatabaseIdentity

public class DatabaseIdentity
extends java.lang.Object

Represents the unique identity of this database, consisting of the omero.db.authority and omero.db.uuid properties. Used primarily to fulfill the LSID contract of globally unique identifiers. On database initialization:

   bin/omero db script
   psql my_database < script
 

a UUID is added to the "configuration" table with the key "omero.db.uuid". This value will be used in all objects exported from this database, so that they can be cleanly re-imported. This implies that it is not safe to copy a database and use it actively while the original database is still running. Only use database copies (or "dumps") as a backup in case of catastrophic failure. A default authority of "export.openmicroscopy.org" is used to simplify initial configuration, but you are welcome to use a domain belonging to you as the authority. If you choose to do so, you will need to use the same authority on any host which you may happen to migrate your database to.
