Topic	XmlBlaster has an advanced queuing facility. Among others one tested persistence layer is offered by communicating with an oracle database.
Des cription	The generic plugin for jdbc based queues has been tested against Oracle 8.1.6, Oracle 9.20 i and 10g (10.1.0.3.0) on Linux and on HP-UX (11.0). 8.1.6 has been tested with the jdbc Driver of 10g with jdk1.4 on Linux and HP-UX and with jdk1.5 on Linux. Oracle is available on http://www.oracle.com where you can find all necessary information and instructions on how to make Oracle run. Once you have a running oracle database you can configure xmlBlaster to make it run against it. Before you need to download the jdbc driver (you need two files for jdk1.3 : the classes12.zip nls_charset12.zip and for jdk1.4 and higher you need ojdbc14.jar files which you can download them from http://otn.oracle.com/software/tech/java/sqlj_jdbc/content.html. You must put these files in the CLASSPATH (for example you can put them into $XMLBLASTER_HOME/lib and add them to the CLASSPATH.
Example Java	These are example QoS of subscribe() invocations: <qos> <queue maxEntriesCache='1000' maxBytesCache='4000' maxEntries='10000' maxBytes='1000000000' onOverflow='deadMessage'/> </qos>
Configure	These parameters allow to configure a cache queue running with postgres Property Default Description Hot Impl QueuePlugin[CACHE][1.0] org.xmlBlaster.util.queue.cache.CacheQueueInterceptorPlugin specifies the cache implementing class to be used queue/maxEntries 1000 specifies the maximum number of entries allowed in this queue queue/maxBytes 10485760 (10MB) specifies the maximum total size allowed in this queue queue/persistent/url jdbc:oracle:thin:@develop:1521:TEST the url which specifies where to find the DB. queue/persistent/user xmlblaster The db user under which to run queue/persistent/password secret The password used together with the user 'xmlblaster' Additionally the configuration parameters for the ram queue and the jdbc queue must be defined. NOTE: Configuration parameters are specified on command line (-someValue 17) or in the xmlBlaster.properties file (someValue=17). See requirement "util.property" for details. Columns named Impl tells you if the feature is implemented. Columns named Hot tells you if the configuration is changeable in hot operation.
