hello,

is there something like like app.data without helma-swarm synchronizing mechanism?

I need it to persist
app.data.userTrackingDBConnection = new helma.Database("xy");

but this won't work within cluster environments

thx
axel

Hi Axel,

I'm not sure I understand. You want a app.data property that is
shared/replicated among helma instances in a cluster? If so, I think
this is what HelmaGroups is about, although I don't know how well it
is supported/updated.

Another option would be to directly access the jgroups channel
infrastructure from helmaswarm if you are already using that, maybe
putting a DistributedHashtable on top of it and storing it somewhere
in the app hierarchy.

BTW, I'm moving this thread to the new google groups helma list, as
the old helma-user list is supposed to be retired. If you answer to
this, please only send to the google groups address.

Hannes
