[jboss-dev-forums] [Design of JBossCache] - Runtime changes of cache config elements

[manik.surtani@jboss.com]

I've created a new annotation to go with org.jboss.cache.config.Configuration - @Dynamic.

This annotation is applied to fields in the Configuration class and if a setter is called on a Configuration object, if the cache is running and the field the setter modifies does not have the @Dynamic annotation a ConfigurationException is thrown.

Easy way to control configuration changes on a running cache - the only question is, which elements should be treated as dynamic?  :)

Here is an initial list of the fields:


  | private String clusterName = "TreeCache-Group";
  |    private String clusterConfig = null;
  |    private boolean useReplQueue = false;
  |    @Dynamic
  |    private int replQueueMaxElements = 1000;
  |    @Dynamic
  |    private long replQueueInterval = 5000;
  |    private boolean useInterceptorMbeans = true;
  |    private boolean fetchInMemoryState = true;
  |    private short replicationVersion = DEFAULT_REPLICATION_VERSION;
  |    private String replVersionString = Version.getVersionString(DEFAULT_REPLICATION_VERSION);
  |    @Dynamic
  |    private long lockAcquisitionTimeout = 10000;
  |    @Dynamic
  |    private long syncReplTimeout = 15000;
  |    private String evictionPolicyClass = null;
  |    private CacheMode cacheMode = CacheMode.LOCAL;
  |    private boolean inactiveOnStartup = false;
  |    private String serviceName;
  |    private long initialStateRetrievalTimeout = 10000;
  |    private IsolationLevel isolationLevel = IsolationLevel.REPEATABLE_READ;
  |    @Dynamic
  |    private Element evictionPolicyConfig = null;
  |    private boolean useRegionBasedMarshalling = false;
  |    private String transactionManagerLookupClass = null;
  |    private Element cacheLoaderConfiguration = null;
  |    @Dynamic
  |    private boolean syncCommitPhase = false;
  |    @Dynamic
  |    private boolean syncRollbackPhase = false;
  |    private Element buddyReplicationConfig;
  |    private boolean nodeLockingOptimistic = false;
  |    private NodeLockingScheme nodeLockingScheme = NodeLockingScheme.PESSIMISTIC;
  |    private String muxServiceName = null;
  |    private String muxStackName = "fc-fast-minimalthreads";
