Hi
Tomcat/tomee session replication; memcached and custom session manager
(hazelcast) solutions are different.
Typically in some of them you accept SPoF, not in others. The perf are not
the same too. Finally guarantees (synchronous or not persistence) can be
different too.

Ok Romain. Im not sure if is tomee issue of msm issue, but i will send you
a mail with the info to the tomee mailing list.

Hello! I am also very interested in having more i.e. docs, examples and
stuff for clustering across the tomee stack. The discussion came up on a
jira some time ago and after that I asked Thomas to write a new post about
it (First part was great!).
For example this is something that sounds really
Hey,
JFYI:
MyFaces+OWB on Tomcat with MSM is working fine.
Don't know about TomEE.

@romain
do you have any article about it? Just for my interesst.
What especially is optimized for tomcat?
I may use TomEE in the future - if our customers allow this.

smiling big... while I wrote OP (last night, my time), I did find Thomas's
long discussion[1] with memcached-session-manager's committer/developer
(Martin). and I remember Thomas said that Martin (the mail list) is 'very
helpful', I think Thomas said that on primefaces forum.
Romain, that
also, i'm still wondering about how database is replicated while clustering
the app.

romain, i have recognized and (gmail) star'red the mail list topics related
to tomee clustering. have not tried yet, but i don't see (any) mention of
how database is replicated while clustering tomee.

interesting response, Jose', thanks!
for some time, I thought that it might be best to have separate server
(tomee + @EJB/DTO's + tomcat's jdbc + database) which is/becomes the
database tier. I guess I need to learn how to do/make remote calls to EJB
server from JSF web layer like you are doing.

hmmm, avoid database replication.
honestly, I think HA-JDBC[1] (clustering the database) is all I really
need, because my app is quite fast, and only bottleneck is database layer.

With the msm you can get away from this.

By the way im not using remote calls. All my apps are in the same ear with
this i can inject my ejb local interface for calling methods in ejb.

Hmmm, i thought you said that you have EAR on one server and database on
separate server. are you running 2 tomee on same server; one tomee = EAR,
another tomee = database?

Ear with all my apps in each server (2 server each with their own ear) then
each server insert/read in another unique db server.

so, db server is on a separate machine/server on the network, and each EAR
is referencing the (one) db server via IP address?
also, do you have an embedded db server (running inside of tomee and using
tomcat jdbc pooling) or network db server/engine?

Yes 2 tomee instances each in separete server point to a third server that
only serve as db

how many concurrent users is your app servingnormally or at peak times?
earlier, i think you mentioned response time is quite fast. did you throw
fast/high-performance hardware at db server, so db server responds fasts to
queries/updates?
do you have any expensive queries or updates...that
I have a early experience with a mini cluster 2 servers using tomee +
memcached for session replication+ sticky session but using 1 only server
for database (i mean i dont use db replication). My jsf apps (ear) are
running in this mini cluster everithyng works fine except when i shutdown
tomee for
26 matches
