How to use replicated Infinispan cache in Wildfly standalone-full-ha - wildfly

Question

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.

Answer 1

Try to directly inject a cache reference (not populating it through the CacheManager). As I understand, this is only way to compel infinispan container to start it in the new WildFly 10.
#Resource(lookup = "java:jboss/infinispan/cache/monitor/default")
private Cache<String, String> cache;
By careful with the JNDI name (default one) or specify it explicitly in configuration

Answer 2

Instead of injecting CacheManager you should inject each cache instance. While doing, keep in mind the following points.
Make sure to enter the correct JNDI name. To avoid any confusion you could explicitly mention the JNDI name in the configuration
Add the transport tag to the cache-container. This is needed for replicated or distributed mode.
Sample Configuration in standalone-full-ha.xml
<cache-container name="replicated_cache" default-cache="default" module="org.wildfly.clustering.server" jndi-name="infinispan/replicated_cache">
<transport lock-timeout="60000"/>
<replicated-cache name="customer" mode="SYNC" jndi-name="infinispan/replicated_cache/customer">
<transaction locking="OPTIMISTIC" mode="FULL_XA"/>
<eviction strategy="NONE"/>
</replicated-cache>
</cache-container>
Inject the resource as follows
#Resource(lookup = "java:jboss/infinispan/replicated_cache/customer")
private Cache<String, Customer> customerCache;
