Using Dataset Manager

Edit online

Dataset Manager is a powerful, flexible tool that enables you to view, evaluate, and relocate Db2 data sets.

When you move data sets using Dataset Manager, you can change the characteristics of the target data set, as well as the location. Dataset Manager takes care of the tasks required when a Db2 data set is moved, such as stopping and starting the associated database and updating the Db2 catalog.

Dataset Manager supports all types of data set allocations, including storage group, user-defined, and data sets managed using SMS. The following types of moves are supported:

  • Move a user-defined data set to a storage group
  • Move a user-defined data set to the same VCAT or from one VCAT to a different VCAT
  • Move a storage group-defined data set to a user-defined VCAT
  • Move a storage group-defined data set to the same storage group or a different storage group

You can modify the following data set characteristics when moving a data set:

  • The primary allocation and secondary allocation values
  • The target volume(s) when moving a non SMS-managed user-defined data set
  • The SMS class information when moving a user-defined data set

The online displays offer various levels of information about the data sets, from the database level down to the individual extent level. You select the desired data sets to be moved, either interactively from within TSO/ISPF or by using the batch function.

If an error occurs when moving a data set, Dataset Manager backs out the move request and returns the data set to its state prior to the move request.
