Use the work sheet to calculate the size of your PDA log data set (long term).

1. Fill in the blanks with values for your installation.

     ________  =  ?UID          -  The high-level qualifier you want to
                                   use for the PDA log data sets.
     ________  =  ?HOSTID       -  The identifier for the processing unit
                                   at your site.
     ________  =  ?TRACEUNIT    -  The unit identifier for the device on
                                   which you want to allocate the PDA log
                                   data sets.
     ________  =  ?TRACEVOL     -  The serial number for the volume on
                                   which you want to put your PDA log
                                   data sets.

2. Allocate the minimum recommended storage for PDA log data sets: 20 cylinders.

   Substitute the values you have provided in step 1 of this work sheet, and run the JCL job shown in Allocating the Problem Determination Aid (PDA) log data sets to allocate and catalog the PDA log data sets.

   If you allocated these data sets as SMS-managed data sets, they must be allocated on a specific volume and they must be associated with a storage class having the GUARANTEED SPACE attribute.

3. Allocate a generation data group (GDG) in which you can archive your site's trace history data.

   The example defines the generation data group (GDG) name for the archived problem determination output data set. Substitute the applicable values you provided in step 1 of this work sheet, and run the JCL job shown in Maintaining a history of Problem Determination Aid (PDA) log data to create a generation data group.

4. Develop a procedure to automatically copy your PDA log data sets to tape.

   The example shows you how to copy the inactive trace data set to tape as a generation data set (GDS). Substitute the applicable values you have provided in step 1 of this work sheet, and run the JCL job shown in Maintaining a history of Problem Determination Aid (PDA) log data to automatically copy your PDA log data sets to tape.
