Hi,
I am not deploying any explicit service.
My Question here is if I am running 2 server nodes then both should be able to
read and write to Ignite, where as in current condition only one application
is able to read from ignite .
Ignite jar are part of Spring application which are deployed on 2 different
Machines.
Below is Piece of code which is running on one machine and not on other
Lock _lock =null;
try {
_lock =
CacheManager.getLock("DSLOCK", JourneyCacheEnum.IGNITE_DS_CACHE);
_lock.lock();
ScanQuery<String,
DecisionSplitWait> scanQuery = new ScanQuery<>(
new
IgniteBiPredicate<String, DecisionSplitWait>() {
private static final long serialVersionUID = 1L;
@Override
public boolean apply(String e1, DecisionSplitWait e2) {
Instant timeLapse = e2.getTimeLapse();
return ObjectUtils.isEmpty(timeLapse) ? true
:
timeLapse.isBefore(Instant.now());
}
});
scanQuery.setPageSize(1);
QueryCursor<Entry<String, DecisionSplitWait>> cursor =
CacheManager.query(scanQuery, JourneyCacheEnum.IGNITE_DS_CACHE);
Iterator<Entry<String, DecisionSplitWait>> iterator = cursor.iterator();
Entry<String,
DecisionSplitWait> entry = null;
if
(iterator.hasNext()) {
entry = iterator.next();
}
if
(!ObjectUtils.isEmpty(entry)) {
key
= entry.getKey();
decisionSplitWait = entry.getValue();
decisionSplitWait.setTimeLapse(Instant.now().plusSeconds(WAIT_TIME_ADDED_FOR_SCAN));
CacheManager.getAndReplace(key, decisionSplitWait,
JourneyCacheEnum.IGNITE_DS_CACHE);
}
}finally {
if(!ObjectUtils.isEmpty(_lock)) {
_lock.unlock();
}
}

Hi,
I think you have a singleton service that has been deployed to a random Ignite
server node. Try checking your service configuration and make sure it contains
at least the following:
svcCfg.setMaxPerNodeCount(1);
svcCfg.setTotalCount(3);
With these properties, you will have one instance of the service across three
nodes. And your service was deployed as:
ig.services(ig.cluster().forServers());

Hey,
Let me explain Architecture
I am running 3 Ignite server nodes ,each have some services which read and
write data from Kafka and also to Ignite
all services(From all servers ) are able to read from kafka and publish it to
Ignite.(Ignite is in replication mode).
But the thread responsible for reading from Ignite are only working on Single
Node.
I have added IP in Logs to identify , which packet is read from which IP .
In logs it clearly shows that all services from all Nodes are able to write to
Ignite , but only Single Node is reading it and publishing it ahead .

Hey,
Sorry, but I don't understand what the issue you mentioned? You are using a
transaction cache and most likely using transactions. Perhaps you are just
having design problems. Tell us more about what you are going to achieve.
Sincerely,

Hi,
Team stuck with Issue with in Ignite Cluster where in Only Single Node is able
to read data from Ignite ,other Nodes are able to write data on to Ignite ,
data is shared with other Nodes,
Below is configuration
cache.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_ASYNC);
cache.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
cache.setCacheMode(CacheMode.REPLICATED);
cache.setGroupName("EngineGroup");
cache.setOnheapCacheEnabled(true);
LruEvictionPolicyFactory lruEvictionPolicyFactory = new
LruEvictionPolicyFactory<>(10000);
lruEvictionPolicyFactory.create();
cache.setEvictionPolicyFactory(lruEvictionPolicyFactory);
TCP/IP Discovery Code
TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
ipFinder.setShared(true);
ipFinder.setAddresses(
Lists.newArrayList(IP1,IP2,IP3));
tcpDiscoverySpi.setIpFinder(ipFinder);
All help appreciated .
