Field Detail

DEFAULT_CHANNEL_PROPERTIES_PRE

public static final java.lang.String DEFAULT_CHANNEL_PROPERTIES_PRE

The first half of the default channel properties. They default channel properties are:

 UDP(mcast_addr=*.*.*.*;mcast_port=45566;ip_ttl=32;mcast_send_buf_size=150000;mcast_recv_buf_size=80000):PING(timeout=2000;num_initial_members=3):MERGE2(min_interval=5000;max_interval=10000):FD_SOCK:VERIFY_SUSPECT(timeout=1500):pbcast.NAKACK(gc_lag=50;retransmit_timeout=300,600,1200,2400,4800):UNICAST(timeout=5000):pbcast.STABLE(desired_avg_gossip=20000):FRAG(frag_size=8096;down_thread=false;up_thread=false):pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;shun=false;print_local_addr=true)
 

Where *.*.*.* is the specified multicast IP, which defaults to 231.12.21.132.

Method Detail

getChannelProperties

public java.lang.String getChannelProperties()

Gets the JavaGroups channel properties. If not specified, default properties will be generated using the multicast IP. Either this or the multicast IP must be set, or else null will be returned.

setChannelProperties

public void setChannelProperties(java.lang.String v)

Sets the JavaGroup channel properties. See the JavaGroups homepage for more imformation. If not specified, default properties will be generated using the multicast IP. Either this or the multicast IP must be set.

getMulticastIP

public java.lang.String getMulticastIP()

Gets the multicast IP address for the JavaGroup.

setMulticastIP

public void setMulticastIP(java.lang.String v)

Sets the multicast IP address for the JavaGroup.

getCacheType

public java.lang.String getCacheType()

Gets the underlying cache type to use on each server. The two options are LRU and Auto.

setCacheType

public void setCacheType(java.lang.String v)

Sets the underlying cache type to use on each server. The two options are LRU and Auto.

getLRUCacheSize

public java.lang.String getLRUCacheSize()

Gets the capacity of the LRU cache. If the cache type is LRU, then this is the maximum number of objects in the LRU queue. Otherwise, this is ignored.

setLRUCacheSize

public void setLRUCacheSize(java.lang.String v)

Sets the capacity of the LRU cache. If the cache type is LRU, then this is the maximum number of objects in the LRU queue. Otherwise, this is ignored.
