To update a catalog entry for a data set

In the dropdown list under Resources on the ESMAC menu, select JES.
Click Catalog in the Resources part of the ESMAC menu.
To limit the entries displayed, enter a filter string in the text field next to the List button. For example, enter "ABC*" to view only those data sets that begin with ABC. You can use a single asterisk as a wild card.
Click the List button.
On the Data Catalog page, click DCB against the entry that you want to update.
Note: No entries are shown on the Data Catalog page until you click the List button. You can use the field adjacent to the List button to enter a filter string to limit the number of entries displayed. For example, enter "ABC*" to view only those data sets that begin with ABC. You can use a single asterisk as a wild card.
Change the properties of the data set as required.
Click Apply.
