Hi All,
I am facing a strange problem : I am trying to cluster 2 (and later 3) caches .
My tests are based on the test.examples.StudentMaintTest. Code remains the same
except for private PojoCache createCache(String name), there is one method for
each of the cache that reads different conf files.
one conf file has :
<TCP bind_addr="10.32.2.48" loopback="true" start_port="7800"
enable_diagnostics="false" />
| <TCPPING down_thread="true"
initial_hosts="10.32.2.48[7800],10.32.2.48[7801]" num_initial_members="3"
port_range="5" timeout="3500" up_thread="true" />
| <MERGE2 max_interval="10000" min_interval="5000"/>
| <FD down_thread="true" max_tries="5" shun="true" timeout="2500"
up_thread="true"/>
| <VERIFY_SUSPECT down_thread="false" timeout="1500" up_thread="false"/>
| <pbcast.NAKACK down_thread="true" gc_lag="100" retransmit_timeout="3000"
up_thread="true"/>
| <pbcast.STABLE desired_avg_gossip="20000" down_thread="false"
up_thread="false"/>
| <pbcast.GMS down_thread="true" join_retry_timeout="2000"
join_timeout="5000" print_local_addr="false" shun="false" up_thread="true"/>
| <pbcast.STATE_TRANSFER down_thread="true" up_thread="true"/>
the other one has :
<TCP bind_addr="10.32.2.48" loopback="true" start_port="7801"
enable_diagnostics="false" />
| <TCPPING down_thread="true"
initial_hosts="10.32.2.48[7800],10.32.2.48[7801]" num_initial_members="3"
port_range="5" timeout="3500" up_thread="true"/>
| <MERGE2 max_interval="10000" min_interval="5000"/>
| <FD down_thread="true" max_tries="5" shun="true" timeout="2500"
up_thread="true"/>
| <VERIFY_SUSPECT down_thread="false" timeout="1500" up_thread="false"/>
| <pbcast.NAKACK down_thread="true" gc_lag="100" retransmit_timeout="3000"
up_thread="true"/>
| <pbcast.STABLE desired_avg_gossip="20000" down_thread="false"
up_thread="false"/>
| <pbcast.GMS down_thread="true" join_retry_timeout="2000"
join_timeout="5000" print_local_addr="false" shun="false" up_thread="true"/>
| <pbcast.STATE_TRANSFER down_thread="true" up_thread="true"/>
and nothing happens (regarding sychronization) test fails :
NullPointerException is thrown when doing joe2.addCourse(bar_); . Joe2 comes
from Student joe2 = (Student) cache2_.getObject("/students/65432");
If I do NOT list all the "servers" in the TCPPING it works !!!
Did I do something wrong in the service.xml files ? or did I really miss
something ?
Thanks for your answers
