[IDD #PGJ-802823]: request for approval of LDM data receiving

I will add an example pattern-action file action to the copy of pqact.conf
that you sent in a previous email; verify that it works in the LDM setup on
my workstation and then mail it back to you later today.

Let's address the logging issue after you have succeeded in getting products
written to disk.

OK, this is good to know.  I assume that you are also implying that the
time on your Windows machine is correct.

How long did you wait?

This may be an artifact.  As soon as we get the saving of data products
working, you will be better able to investigate monitoring of receipt
of products.  By the way, the other way to monitor the receipt of
products is by using the LDM utility 'notifyme'.  Here is an example:

<as 'ldm'>
notifyme -vl- -f ANY

re:
> > OK, I added the following lines to pqact.conf:
> EXP<tab>([12][0-9][0-9][0-9])\.([0-3][0-9][0-9])(bfr|ion|wet)Prf(.*\.nc)
> <tab>FILE<tab>-close
> <tab>/home/ldm/var/data/\1\2/\3Prf/\3Prf\4

I assume that you substituted a tab character for the <tab> values above.

re:

Again, I will create a working action in a vanilla pqact.conf file and
send you the file this afternoon.

re:
> Is the configuration of LDM supposed to be this weird?

No, not at all.  Most folks do not run into the problems you are seeing.

re:

It is too bad that we can't logon to your machine to make sure that
things are setup correctly.

re:
> Thanks for help and regards!!

No worries.

Cheers,

Tom
