I would like to use a replicated Infinispan cache using two Wildfly standalone instances. I want to insert a value on one node and I should be able to read it on the other node.
Here's what I tried:
- I unzipped the full WF10 distribution using two different virtual maschines running Debian Jessie.
- I run both maschines with the standalone-full-ha.xml config.
- I changed the binding from localhost to the IP adresses of the VMs - all ports are reachable from outside.
- I added another cache by inserting the following code to the config:
<subsystem xmlns="urn:jboss:domain:infinispan:4.0">
<cache-container name="monitor" default-cache="default">
<transport lock-timeout="60000"/>
<replicated-cache name="default" mode="SYNC">
<transaction mode="BATCH"/>
</replicated-cache>
</cache-container>
...
- The rest of the configuration is not modified.
- On both nodes I get the following log entries (my interpretation is - both nodes see each other):
2016-03-13 11:19:43,160 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-1) ISPN000094: Received new cluster view for channel monitor: [wf1|5] (2) [wf1, wf2]
- On one node I created a cache writer. On the other node a cache reader is deployed:
@Singleton
@Startup
public class CacheWriter {
private final static Logger LOG = LoggerFactory.getLogger(CacheWriter.class);
@Resource(lookup = "java:jboss/infinispan/container/monitor")
private EmbeddedCacheManager cacheManager;
private Cache<String, String> cache;
@PostConstruct
public void init() {
cache = cacheManager.getCache();
LOG.info("Cache name: " + cache.getName());
}
@Schedule(hour = "*", minute = "*", second = "0", persistent = false)
public void createDateString() {
Long date = new Date().getTime();
updateCache("date", date.toString());
}
public void updateCache(String key, String value) {
if (cache.containsKey("date")) {
LOG.info("Update date value: " + value);
cache.put(key, value);
} else {
LOG.info("Create date value: " + value);
cache.put(key, value);
}
}
}
@Singleton
@Startup
public class CacheReader {
private final static Logger LOG = LoggerFactory.getLogger(CacheReader.class);
@Resource(lookup = "java:jboss/infinispan/container/monitor")
private EmbeddedCacheManager cacheManager;
private Cache<String, String> cache;
@PostConstruct
public void init() {
cache = cacheManager.getCache();
LOG.info("Cache name: " + cache.getName());
}
@Schedule(hour = "*", minute = "*", second = "10", persistent = false)
public void readDateString() {
LOG.info("Cache size: " + cache.keySet().size());
if (cache.containsKey("date")) {
LOG.info("The date value is: " + cache.get("date"));
} else {
LOG.warn("No date value found");
}
}
}
The values on the writer are inserted but there are no cache modifications on the reader node and the cache size is always 0. I tried the TCP and the UDP stack. What am I missing? Can you help me.
Thanks in advance.
