Hi infinispan jboss,

I advise you to take a look at quick-start: QuickStart

Also, it may be useful to take a look in the user guide: UserGuide

If you have a more precise question let me know.

Cheers,

Pedro

Hi Pedro,

     thanks  for  respond to this,

     when i used Infinispan in distribution mode with numOwners=1 data is not shared across multiple nodes,,when i used numOwners=2 data is shared...what might be the problem??

thanks,

[nadirx]

That's expected: numOwners=1 means there is only one owner for each element, therefore no redundancy.

hi tristan,

  if i used numOwners=1 data is stored on first node,thats ok.But if want to access data from second node i am not able to access .The value is null..can u provide any help on this.

Does the cluster form ? Is state transfer enabled ? Can we see your configuration (both Infinispan and JGroups) and possibly a debug log of the startup of the application ?

[mvpratap]

yes cluster formed and state transfer is also enabled..these are my config files

I am using same configuration in both nodes(192.168.2.2,192.168.1.1) ,,

help me is there any configuration problem

[nadirx]

Why is the TCP bind_addr="131.10.20.16"  instead of 192.168.x.y ?

[mvpratap]

i forgot to change that it is also 192.168.1.1..

if i use numOwners=1 on both nodes,on first node i add some data to cache,but it is added to second node why???
