MBean's CacheManager attribute ClusterSize does not reflect the cluster topology when no cache is looked up
-----------------------------------------------------------------------------------------------------------
Key: ISPN-1044
URL: https://issues.jboss.org/browse/ISPN-1044
Project: Infinispan
Issue Type: Bug
Components: JMX, reporting and management
Affects Versions: 5.0.0.BETA1
Reporter: Emmanuel Bernard
Assignee: Manik Surtani
{code}EmbeddedCacheManager manager = createCustomCacheManager( "default-config.xml", new Properties() );
manager.start();
MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
final String defaultDomain = mbs.getDefaultDomain();
ObjectName name = new ObjectName( "org.infinispan:type=CacheManager,name=\"HibernateOGM\",component=CacheManager" );
//uncomment to "fix" the bug and gat the right cluster size
//final Cache<Object,Object> instances = manager.getCache( "INSTANCES" );
for (;;) {
Thread.sleep( 5000 );
System.out.print( "\nCluster size: " + mbs.getAttribute( name, "ClusterSize" ) );
}
{code}
The code will only show 'Cluster size: 1' unless final Cache<Object,Object> instances = manager.getCache( "INSTANCES" ); is uncommented

[JBoss JIRA] Created: (ISPN-888) Support both Synchronization and XAResource for interacting with the TransactionManager
by Mircea Markus (JIRA)
Support both Synchronization and XAResource for interacting with the TransactionManager
---------------------------------------------------------------------------------------
Key: ISPN-888
URL: https://issues.jboss.org/browse/ISPN-888
Project: Infinispan
Issue Type: Feature Request
Components: Transactions
Affects Versions: 4.2.0.Final
Reporter: Mircea Markus
Assignee: Mircea Markus
Fix For: 5.0.0.Final
This might be a configuration option on <transaction registerSynchronization="true" .../>. This would be false by default.
Syncs have the advantage that TMs can optimise 2PC with a 1PC where only 1 XAResource is present.
Useful when used as a simple cache in front of a DB. E.g., as a Hibernate second level cache: if the cache would register itself with the TM as a XAResource than at commit time, the TM would see two XAResources (cache and db) and would not be able to make this optimization. This means that it would write to disk tx logs - time consuming.

[JBoss JIRA] Created: (ISPN-955) Allow HotRod server to be passed a cache manager class to be used instead of DefaultCacheManager
by Octavian Florescu (JIRA)
Allow HotRod server to be passed a cache manager class to be used instead of DefaultCacheManager
------------------------------------------------------------------------------------------------
Key: ISPN-955
URL: https://issues.jboss.org/browse/ISPN-955
Project: Infinispan
Issue Type: Enhancement
Components: Cache Server
Affects Versions: 5.0.0.ALPHA3
Environment: 4.2.1.CR1
Reporter: Octavian Florescu
Assignee: Manik Surtani
The cache manager class used by HotRod server is not pluggable. org.infinispan.server.core.Main always uses DefaultCacheManager.
Allow passing in the name of a user supplied class implementing EmbeddedCacheManager thought some mean (eg a param).
I implemented this functionality already (see bellow, look for the addition of -f param), so I hope something like this makes it into 5.0.0
