Programmierung von Partitionsgruppen

In der Methode getPartitions einer Partitioned Stateless Session Bean (PSSB) ordnen Sie denselben Partitionsalias mehreren Partitionen zu. Dabei wird für einen Teil von Partitionen ein Partitionsgruppenkontext erstellt.

Im folgenden Beispiel (WPFPartitionGroupingSample.ear) entspricht die Anzahl der Partitionsgruppen der Hälfte (1/2) der Partitionen. Jede Partitionsgruppe enthält zwei Partitionen:

public PartitionDefinition[] getPartitions() {	
		try {
          numOfAlias=Math.round(numOfPartitions/2.0f);
			partitionAlias= new String[numOfAlias];
		}
      catch(Exception e){
……
		}
		PartitionDefinition[] rc = new PartitionDefinition[numOfPartitions];
		for (int i = 1; i <= numOfPartitions; ++i) {
			rc[i - 1] = ivManager.createPartitionDefinition(PartitionGrouping.PARTITION_PREFIX + padZeroToString(i + "", 6));
			int k= Math.round((i-1)/2.0f-0.1f)+1; 
						rc[i-1].setPartitionAlias(PartitionGrouping.PARTITION_ALIAS + padZeroToString(k + "", 6));
		}
	} 

Laufzeitumgebung eines Partitionsalias

Die Datei WPFPartitionGroupingSample.ear enthält Quellcode. D_WPFPartitionGroupingSample.ear ist ein implementiertes Enterprise Archive (EAR).

Beide Dateien befinden sich im Verzeichnis [WAS_HOME]/profiles/[PROFIL]/installableApps. Installieren Sie D_WPFPartitionGroupingSample.ear. Rufen Sie eine Befehlszeile auf und wechseln Sie dort in das Verzeichnis c:\XD60-Installationsverzeichnis><bin>. Geben Sie anschließend den folgenden Befehl ein:
launchClient D_WPFPartitionGroupingSample.ear -CCBootstrapPort=9813

Das Ergebnis ist der folgende Code:

PartitionAlias Context Routing Sample has 10 partitions
PartitionAlias Context Routing Sample has 5 alias
Partition alias groups different partitions and router does WLM for each alias
that has more than 1 partitions.
This sample shows that alias context will be routed into 2 different (even and
odd) partitions:
