Hi,
Do you use cluster with persistence? After first actication all your
data will be located on the first activated node.
In this case, you also should track your baseline.
https://www.gridgain.com/docs/latest/developers-guide/baseline-topology
Baseline topology is a subset of nodes where you cache data located.
The recommendations are the following:
1)you should activate the cluster only when all server nodes were started
2)If the topology changes, you must either restore the failed nodes or
reset to the base topology to trigger partition reassignment and
rebalancing.
3)If some new node should contain the cache data then you should add
this node to baseline topology:
using java code:
https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/IgniteCluster.html#setBaselineTopology-java.util.Collection-
using utility tool:
https://www.gridgain.com/docs/latest/administrators-guide/control-script#adding-nodes-to-baseline-topology
4)In case if some node from baseline can't be started (e.g because its
data on the disk was destroyed) it should be removed from baseline:
https://www.gridgain.com/docs/latest/administrators-guide/control-script#removing-nodes-from-baseline-topology
If you are not using persistence, please provide additional information
that "data is being added to the cache but not available to any of the
modules." means:
1) How you access data
2) What do you see in the logs

Andrei

Hi,
I have two module(Web and Engine) and want to share data b/w the
modules , but when I run web and engine together , data is added to
cache but is not available to either of modules.
below is my ignite config, which is same in both modules
config.setActiveOnStart(*true*);
config.setAutoActivationEnabled(*true*);
config.setIgniteHome(propertyReader.getProperty("spring.ignite.storage.path"));
config.setFailureHandler(*new*StopNodeOrHaltFailureHandler());
config.setDataStorageConfiguration(getDataStorageConfiguration());
config.setGridLogger(*new*JavaLogger(java.util.logging.Logger./getLogger/(*/LOG/*.getClass().getCanonicalName())));
Ignite ignite= Ignition./start/(config);
ignite.cluster().active(*true*);
All Caches created have below properties |
cache.setWriteSynchronizationMode(CacheWriteSynchronizationMode.*/FULL_ASYNC/*);
cache.setAtomicityMode(CacheAtomicityMode.*/TRANSACTIONAL/*);
cache.setCacheMode(CacheMode.*/REPLICATED/*);
cache.setGroupName("EngineGroup");
Both Modules are running on IP List :
127.0.0.1:47501,127.0.0.1:47502,127.0.0.1:47503,127.0.0.1:47504
Please suggest..
