public PingJndi()

Method Detail

getLookupNames

public String[] getLookupNames()

Get the names of JNDI bindings that should be queried on each host

Specified by:: getLookupNames in interface PingJndiMBean

Returns:: the array of target names to test

setLookupNames

public void setLookupNames(String[] names)

Set the names of JNDI bindings that should be queried on each host

Specified by:: setLookupNames in interface PingJndiMBean

Parameters:: names -

getProviderURLPattern

public String getProviderURLPattern()

Get the Context.PROVIDER_URL regular expression.

Specified by:: getProviderURLPattern in interface PingJndiMBean

Returns:: the regular expression containing the host, for example 'jnp://(host):1099/'

setProviderURLPattern

public void setProviderURLPattern(String regex)

Set the regular expression containing the hostname/IP address of the JNDI provider. This expression is used to build the JNDI Context.PROVIDER_URL for each node in the cluster. The expression should contain a "(host)" component that will be replaced with the cluster node hostname.

Specified by:: setProviderURLPattern in interface PingJndiMBean

Parameters:: regex - the regular expression containing the host, for example 'jnp://(host):1099/'

membershipChanged

public void membershipChanged(ArrayList removed,
                              ArrayList added,
                              ArrayList members,
                              String logCategoryName)

The TopologyMonitorService trigger callback operation.

Specified by:: membershipChanged in interface PingJndiMBean

Parameters:: removed - ArrayList of nodes that were removed; added - ArrayList of nodes that were added; members - ArrayList of nodes currently in the cluster; logCategoryName - the log4j category name used by the TopologyMonitorService. This is used for logging to integrate with the TopologyMonitorService output.
