Defining and initializing IMS databases

When you are developing applications that access IMS databases, there are times when you want to empty your data sets and start to input the data again. FM/IMS provides a mechanism for you to:

• Delete and redefine the data sets associated with an IMS database.
• Initialize the database, so that it can be used in the edit or load process.
• Load data into an uninitialized IMS database (see Loading into an uninitialized database).

The tasks described in this section are:

• Deleting and redefining your data sets
• Initializing an empty database
