Use the DB.6 panel to change the characteristics of a data set by entering the UPD function and the changed field values.
One of the more common uses of this panel is that of renaming data sets. If the DCB for this data set is not changing, all that you must enter is the RENAME function and the NEWNAME for the data set. This panel changes the data set name in the CA WA CA 7 Edition database. To change the data set name in z/OS, use the RENAME top line utility command.
If the DCB attributes change, be sure that the SMF indicator has the proper value for the situation. If the system is to pick up automatically the DCB characteristics, set the SMF indicator to Y. The appropriate DCB field cleared to blanks or zeros.
Note: Ensure that the RENAME occurs before changing JCL and loading of jobs. If not, the DB.3.1 updates sometimes need to be manually performed to disconnect the old data set name.
