VBJ Implementation: ORB.init

• org.omg.CORBA.ORB.init(...)

• This class reads the property "org.omg.CORBA.ORBClass" and instantiates the
  the class using newInstance


• Calls set_parameters(...)

• This call comes to com.inprise.vbroker.orb.ORB class
• initializes the com.inprise.vbroker.properties.PropertyManager and is cached in ORB
• Processes the command-line and VM properties using com.inprise.vbroker.properties.CommandLineProcessor

• PropertyManager has a ChainProperties class which keeps an assortment of properties of different types such as command line properties, system properties (VM), properties loaded from file and some others.
• Command-line and VM properties are added to the ChainProperties

• Command-line parameters starting with -OA or -vbroker are added directly into the command line property set in the chainProperties. While adding, any templates are expanded. Any properties starting with -ORB are migrated to new properties and added in.
• Similarly, the system properties (VM) are processed and added to the ChainProperties in the PropertyManager

• Call initialize()

• The properties passed in during ORB.init() are now processed as above and added to PropertyManager
  which is internally cached in ORB properties set.
• File ORB.properties is then read and all the properties are again processed and added to the
  PropertyManager into DEF_PROPS bucket
• Properties are then read from the file pointed by ORBpropStorage and loaded into FILE_PROPS bucket.
• If the property vbroker.orb.propOrdering is set, then the buckets in the ChainProperties is ordered
  to be compliant to be with the specified ordering
• Initialize Web Service
• Initialize Logger
• Instantiates a new com.inprise.vbroker.interceptor.Init; This class implements com.inprise.vbroker.interceptor.ServiceLoader interface
  and has init, init_completed and shutdown API
• Calls init()
• Instantiates a new com.inprise.vbroker.interceptor.InterceptorManagerImpl object
  which implements InterceptorManagerControl which has API to get_manager

• Constructor initialize the following interceptor managers

• "Bind" -> BindInterceptorManagerExt
• "POALifeCycle" -> POALifeCycleInterceptorManagerExt
• "ServiceResolver" -> ServiceResolverInterceptorManagerExt
• "PolicyCreation" -> PolicyInterceptorManagerExt
• "URL" -> URLInterceptorManager
• "ObjectKeyAliasing" -> ObjectKeyAliasInterceptorManager
• "Connection" -> ConnectionInterceptorManager
• "POACreation" -> POACreationInterceptorManager
• "GlobalServerRequest" -> ServerRequestInterceptorManagerExt
• "GlobalIORCreation" -> IORCreationInterceptorManagerExt
• "EventQueue" -> EventQueueManager

• Add another ServiceResolver for resolving the Control with following name
  "VisiBrokerInterceptorControl"

• Create a new instance of ProtocolManager of type com.inprise.vbroker.ProtocolEngine.ManagerImpl
  Initialize the various Protocol Engine bits. The factories are all anonymous objects that create the
  objects that are shown after th "->"

• Server Engine factory -> com.inprise.vbroker.ProtocolEngine.ServerEngineImpl
• Threadpool Dispatcher factory -> com.inprise.vbroker.orb.TPDispatcherImpl
• NIO Threadpool Dispatcher factory -> com.inprise.vbroker.orb.TPDispatcherImplNio
• Thread Session Dispatcher factory -> com.inprise.vbroker.orb.TSDispatcherImpl
• Main Thread Dispatcher factory -> com.inprise.vbroker.orb.MTDispatcherImpl
• Connection Pool factory -> com.inprise.vbroker.orb.ConnectionPool
• Socket Server Connection Manager factory -> com.inprise.vbroker.orb.SocketSCM
• NIO Socket Server Connection Manager factory -> com.inprise.vbroker.orb.SocketSCMnio

• URL manager is cached and the following URL resolvers are installed. URL resolver have
  this notion of supported protocols which they can resolve.

• com.inprise.vbroker.IIOP.IIOPLocResolver
• com.inprise.vbroker.IIOP.CorbaLocResolver
• com.inprise.vbroker.IIOP.IIOPNameResolver

• Install all Service loaders listed in the property vbroker.orb.systemLibs.application property.
  In this case, the property value points to service loaders.
• Install all the Service loaders listed in the property vbroker.orb.dynamicLibs.
  The funny thing in this case is that vbroker.orb.dynamicLibs is a prefix and there could
  be number of vbroker.orb.dynamicLibs.<xxx> properties for example vbroker.orb.dynamicLibs.naming
  and the value of these properties will be the actual service loaders. Also, for each of these,
  the value could be comma separated list.
• Each of the Service Loaders thus found is then initialized by calling Init().

• com.inprise.vbroker.IIOP.Init
• com.inprise.vbroker.LIOP.Init
• com.inprise.vbroker.qos.Init
• com.inprise.vbroker.ds.Init
• com.inprise.vbroker.URLNaming.Init
• com.inprise.vbroker.dynamic.Init
• com.inprise.vbroker.ir.Init
• com.inprise.vbroker.naming.Init
• com.inprise.vbroker.ServerManager.Init
• com.inprise.vbroker.IOP.Init
• com.inprise.vbroker.CONV_FRAME.Init
• com.inprise.vbroker.PortableInterceptor.Init
• com.inprise.vbroker.rmi.CORBA.Init
• com.borland.vbroker.notify.Init
• com.borland.vbroker.CosTime.Init
• com.inprise.vbroker.naming.Initilize

• ORB initializers are now installed

• Property org.omg.PortableInterceptor.ORBInitializerClass is
  used as prefix. All the property names starting with prefix is got
  and the actual Initializer class are the suffix after removing the
  prefix and added to a collection
• If the property vbroker.orb.enableNativeMessaging is true, then
  the init class com.borland.vbroker.NativeMessaging.Init is added to
  the collection.
• com.borland.security.core.Init is always added to the collection.
• All the classes are now loaded and instantiated and added to the
  _services and _orbInitializer lists.

• Add com.inprise.vbroker.poa.POABidder as client engine
• Register value factories for VisiObjectReferenceTemplate and VisiTransientObjectReferenceTemplate.
• Call the pre_init and post_init operations on the ORB initializers.
• Cache all the property settings in the ORB such as vbroker.orb.tcIndirection.
  There are lot of such properties cached here.
• Call complete_init() on all the ServiceLoaders now.
