Question:

When do you need to allocate a data set for a certificate and what are the attributes needed for certificate data sets?

Answer:

Data sets associated with Top Secret commands such as a TSS gencert, genreq or export that put a certificate into a data set cannot be pre-allocated.  They will be allocated by issuing the command(s).

If you are not issuing Top Secret commands to put the certificate in a data set then you have to allocate the data set.
The data set needs the following attributes: 

DSORG = PS and RECFM = VB. 

Any other attributes are not specific and can usually take a default value.  Only the two above are mandatory values.
