Hi all,
Concerning portability again :-)
Is there any way I can add in the memory all the numbers with
portability? (2.000.000 rows)?
And also reload these data a few times a day and access this data from
the Kamailio script?
while I advise usage of sqlops/sql_query() instead of
avpops/avp_db_query(), if you want to load such data in memory should be
in shared memory. For that look at htable or maybe you can re-use pdt.
Cheers,
Daniel

There are the $var PVs you already mentioned, and then also the
$shv that
are shared variables. But they are (process) global, and not
transactional. Daniel proposed and developed the new xavp type for sr
which are basically extended AVPs. More informations can be found
