Viewing the data sets for an alias

To view the data sets that are using a particular alias:

Procedure

Specify D next to an alias.
Because IMS Recovery Expert does not save individual data set information in its repository, this command might require you to reanalyze the system if you have not performed a recent analysis. You are not required to perform the analysis, however, IMS Recovery Expert will not be able to display information about tracks, volume, or data type for data sets.

```
                   Re-Analyze System?                   
 BSY$SSRX                                               
   This command requires a current analysis to show     
   which data sets are in use by this IMS.  If you do    
   not perform the analysis, all data sets will still    
   be shown but will have a status of "N/A".  Do you    
   want to perform the analysis now?       Y
```
Press Enter.

Optional: If analysis is needed, specify Y on the Re-Analyze System panel and press Enter. After analysis (or if you are not viewing a previously saved analysis), the Alias Dataset Display panel is displayed.

IMS data sets related to the selected subsystem are shown in ISPF default color blue. Non-IMS data sets are highlighted in the ISPF default color turquoise. Your colors might be displayed differently if you have changed your ISPF default colors.

At the top of the panel, the following information about the IMS environment and alias for which you are viewing data sets is displayed:

Data set Name: The fully qualified name of the data set.
Tracks: The number of tracks allocated for the data set.
Volume: The volume on which the data set is located, or the data set type if the data set is not physically allocated on the volume.
IMS: The value in this column is set to Yes if the data set is an IMS data set for the selected IMS environment.
Sys: The value in this column is set to Yes if the data set is an IMS active or archive log data set or an IMS system data set for the selected IMS environment.
Data: The value in this column is set to Yes if the data set is an IMS database data set for the selected IMS environment.
