This topic tells you how the messaging engine sets up its data store and what to do when you delete a messaging engine.
When starting, a messaging engine performs checks on the tables that comprise the data store to determine whether they are suitable. If the tables do not exist, and the user has selected the Create tables option when configuring the messaging engine, the messaging engine attempts to create the tables. Otherwise, your database administrator must create the tables beforehand, using the DDL statements generated by the sibDDLGenerator command.
