[pca] PCA

[little help]

I  wanted to get feedback on what other are doing when installing patches.
For hosts in the environment I am trying to decide if I simply install all
patches or missingrs?  I am aware of the added time and somewhat risk that
installing all introduces, but I have not had a problem and it seems to be
"best practice".  Which one would be closer to the patch cluster?

Also, I have a number of DMZ hosts, as well as hosts on the private networks
that cannot access our proxy server to download the patchdiag.xref file,
when I run the pca command.  If I copy the file manually to the /var/tmp/ is
works fine.  I am wondering if there is an option I can use to have the
client try to download the latest file and if not use a default location.  I
am aware of the -X (--xrefdir) option but I would like to use this as a
secondary should the download of the latest file fail.  I have been a able
to accomplish this with

pca --dltries=1 -X=/location_to_file

Is there a "cleaner" way?
