You would need two cron jobs with two different xml
configuration files (one for each database) in any machine with an apel parser
installed.
As for the second question, the db doesn’t only contain the
accounting records, it also has information on which log files have been
processed and the last successful publishing date, so it would be very
recommended to move the db back to the MON (in order to avoid reprocessing log
files, republishing data and so on…).
Cheers,
Cristina

Hi Santanu,
The problem is that your CE(s) will only be pointing to one of
the machines, so you’ll only have records in one of them…
As far as I understand, all it (the CE) does is runs the
cron-job, which actually runs the parser-config.xml in return to generate the
data - isn't it?
If so, then is it a problem to have two separate files - one with
reprocess="no" and another with reprocess="yes" - and
running the cron-jobs in two different time?
If the plan is to keep the MON box running but for the CEs to
use the glite-APEL box and if this fails move back to the MON box then that’s
fine… Just remember that if you move back to using the MON box you should move
the contents of the db as well.
Just a question: If the accounting-page is found up-to-date,
do we still need to think about the db?

Santanu
Please open a GGUS ticket if you have any problems with the
installation or with APEL.
Cheers,
Cristina

Hi Cristina
HI Santanu,
You can have both nodes specified in GOCDB, that’s not a problem.
However, having both the new glite-APEL and the old MON running
at the same time is a bit more tricky. Are you planning to have both publishing
records for a while?
Not for a very long time, for sure but just for a little
while, until I'm happy from my side. It's actually a virtual machine - that's
another thing I'm testing too for the production. So the idea is to keep
running the old one as backup if the new one fails.
cheers,
Santanu
