ORB Interface: Policy Object (4.9) The Policy interface is not available in IDL, but is instead available through nsdorb/corba.h in C++ and through org.omg.CORBA.Policy in Java. ORB Interface Thread-Related Operations: perform_work (4.11.2) How an application and the ORB arrange to use compatible threading primitives is platform-specific. For C++ NonStop CORBA provides two sets of threading primitives: ● An object-oriented set of primitives in the header file nsdevent/vthread.h.
The Portable Object Adaptor: create_POA (11.3.8.2) For C++, the third parameter of the signature for create_POA() takes a CORBA::PolicyList_ptr instead of a CORBA::PolicyList passed by reference. The Portable Object Adaptor: Policy Creation Operations (11.3.8.5) For C++, NonStop CORBA adds StatePolicy and create_state_policy (in StatePolicyValue value), with values STATELESS and STATEFUL. The default is STATEFUL.

Transaction Service Table of Contents Overview Nested Transactions (1.2.4.1) Service Architecture: Transaction Context (1.3.2) Service Architecture: Exceptions (1.3.6) Current Interface (2.1.1) TransactionFactory Interface (2.1.2) Coordinator Interface: get_transaction_name (2.1.5.15) RecoveryCoordinator Interface: replay_completion (2.1.6.1) TransactionalObject Interface (2.1.10) The User's View: Application Programming Models (2.2.
Nested Transactions (1.2.4.1) The specification defines nested transactions. These transactions are optional and are not supported by NSOTS. Service Architecture: Transaction Context (1.3.2) NSOTS does not support the transactional Dynamic Invocation Interface. Service Architecture: Exceptions (1.3.6) In general, NSOTS does not provide exception minor codes. However, when an exception is initiated by Open TMF, NSOTS assigns the TMF error code to the CORBA exception minor code. Current Interface (2.1.
resource is still required to wait for Resource::commit() or Resource::rollback() to be invoked. The RecoveryCoordinator will only be used by very sophisticated server applications. TransactionalObject Interface (2.1.10) The specification says that an object that supports the TransactionalObject indicates that it wants the transactional context associated with the client thread to be associated with all operations on its interface.
Model Interoperability (2.3.3) The specification provides for interoperability with X/Open DTP through the TX and XA interfaces. NSOTS does not support those interfaces because the TMF subsystem is the native transaction manager for HP NonStop Kernel operating system environments (not X/Open). NSOTS extends the Current interface with the tmf_start(xid) and tmf_end() procedures (where xid is a transaction identifier obtained from tmf_get_tx_id_() ). They correspond to X/Open xa_start() and xa_end().

Invoked by a transfer (client or server) event handler, this method notifies the transfer event-handler user that the connection has been terminated. unsigned long header_in( Fw_MD *pp_MD ) Delivers the first pv_header_size bytes of a message. For TCP/IP, pv_header_size (the length of the message header) is determined by the set_header_size method of the transfer (client or server) event handler. Class Fw_Transfer_EH The base class for client and server event handlers.
API Methods If your application includes a client event handler user implementation, it must implement all of the following methods that it uses, except those method implementations (if any) that it inherits from the NSDEFw_GFS class. Fw_Client_EH_User() Creates an Fw_Client_EH_User object. ~Fw_Client_EH_User() Destructor for the current Fw_Client_EH_User object. void connected() Invoked by a client event handler when it has successfully established a connection with its peer.
If connect returns true, the client event-handler user should expect to be called with either the connected or connect_failed method. Class Fw_Server_EH_User The base class for server event-handler users, a role played by the transfer portion of a client wrapper. This class is derived from the Fw_Transfer_EH_User class. API Data Fw_Server_EH *ip_EH Allows an implementation to store the pointer to the event handler associated with a server event-handler user.
~Fw_Server_EH() Destructor for the current Fw_Server_EH object. bool accept( void *pp_client_address ) Directs the server event handler to accept the connection with the peer indicated by the transport-dependent pp_client_address. The result of this method indicates whether the server event handler succeeded in accepting the connection. Class Fw_Listener_EH_User The base class for listener event-handler users, a role played by the listener portion of a client wrapper.
API Methods If your application includes a listener event handler implementation, it must implement all of the following methods that it uses, except those method implementations (if any) that it inherits from the NSDEFw_GFS class or either of the classes Fw_Sock_Client_EH or Fw_Sock_Server_EH. Fw_Listener_EH() Creates an Fw_Listener_EH object. ~Fw_Listener_EH() Destructor for the current Fw_Listener_EH object.

IO_Type: Close_Msg, CPU_Down_Msg, Dialog_Abort_Msg, Open_Msg, Process_Deletion_Msg, Read_Msg, Write_Msg, Write_Read_Msg, Unknown_Msg Messages expected by Receive_EH. Dialog_Flags: Dialog_Abort, Dialog_Begin, Dialog_Middle, Not_Dialog For context-sensitive NonStop TS/MP (Pathsend) messages (the server end of a TS/MP dialogue is implemented with Guardian file-system components).
static Address* get_address() Factory. Use this instead of new. static put_address( Address* pp_address ) Recycler. Use this instead of delete. static unsigned hash( const Address& pr_address ) Rogue Wave tools.h dictionary-compatible hash method. bool operator==( const Address& pr_RHS ) Returns true if the instance and the right-hand side string compare on all API strings. API Data Declared in the header file, the following arrays are large enough to hold the standard Guardian file-system strings.
Destructor. API Data Fw_MD *ip_MD Pointer to a message data object. For delivering the results of READ operations to the event handler. Event *ip_next For chained events, can be used as a pointer to the next event in the chain. short iv_count Contains the completion count for the operation (as in AWAITIO). short iv_FE Contains any Guardian file-system error codes returned by the operation. Key iv_key Associates the FS Client Event object with the I/O operation it represents.
Destructor. unsigned hash( const Key &pr_key ) Static method that, given a Key, will generate a value usable by Rogue Wave dictionaries. int operator==( const Key &pr_RHS ) Compares the instance with the parameter on the right-hand side. Returns true if the two keys have identical values for iv_FN and iv_tag. API Data short iv_FN File number associated with operation. unsigned long iv_tag Nowait tag associated with operation.
appropriate with the I/O event. static void put_EH( EH *pp_EH ) Recycler. void send_message( Fw_Message *pp_msg ) Tells the event handler to deliver a full message over the event handlers connection. API Data Address *ip_address From the open message data, uniquely identifies the connection within this process. EH *ip_next For chained events, can be used as a pointer to the next event in the chain. short iv_file_number The clients file number associated with the connection.
void unregister_listener( Listener::Address *pp_address ) Removes the entry at pp_address from the listener dctionary. void unregister_server( Server::Address *pp_address ) Removes the entry at pp_address from the server dictionary. NSDEFw_GFS::Server Implements the Fw_Server_EH role using the other Guardian file-system server components. Class NSDEFw_GFS::Server::Address Provides a hashable abstraction used by Guardian file-system servers to uniquely identify connections.
Event() Constructor that creates an Event object. ~Event() Destructor. void reply( FE pv_FE ) A server event handler object calls this method when it has processed the event and associated any response message data with the event. API Data Fw_MD* ip_MD Points to any data associated with the I/O. Write data is attached by the Receive_EH. Read data is attached by an event handler for delivery to the client. Event* ip_next For chained events, can be used as a pointer to the next event in the chain.
void disconnect() Resets the event handler. void handle_event( Event *pp_event ) This method is invoked by a callback from the NonStop CORBA event framework when the event framework receives an I/O event of a type registered by the event handler. A legacy client wrapper must implement this method when playing the role of the server event handler. The implementation should do whatever is appropriate with the I/O event. void send_message( Fw_Message *pp_msg ) Queues the messages MDs to be sent.
Class NSDEFw_GFS::Listener::Event Events are generated by the Receive_EH upon receipt of OPEN messages. API Methods Event() Constructor that creates an NSDEFw_GFS::Listener::Event object. ~Event() Destructor for NSDEFw_GFS::Listener::Event objects. void reply( FE pv_FE ) Results in calling REPLYX to complete the Guardian file-system OPEN. API Data Server::Address *ip_address From the open message data, uniquely identifies the connection within this process. short iv_message_tag From FILE_GETRECEIVEINFO_.
void stop_listening() Called by a listener event handler user. Unregisters itself from the Receive_EH. gcfehoss.h Classes In general, the classes, methods, and data items declared in the gcfehoss.h header file ($NSD_ROOT/include/nsdevent/gcfehoss.h) are for internal use by NonStop CORBA. The single method described below, however, can be used in legacy server wrappers that issue nowait Pathsend requests without the use of a jacket procedure.
Saves an Fw_MD and its buffer for later reuse. This is the preferred method for disposing of an Fw_MD. static Fw_MD *get_3_tuple( const unsigned long pv_buffer_length ); Returns a new or recycled Fw_MD that is associated with a new or recycled buffer of the size indicated by pv_buffer_length. The default size (Fw_Message::DEFAULT_BUFFER_SIZE) should be passed as pv_buffer_length unless a larger buffer is desired for efficiency reasons.
void reset( void ); Combination of reset_read and reset_write. void reset_read( void ); Returns ip_user_read and iv_data_bytes to their original values. void reset_write( void ); Returns ip_user_write, iv_data_bytes, and iv_free_bytes to their original values. static void set_test_no_MDs( const bool pv_no_MDs ); Allows simulation of resource shortage for testing what happens if the ORB cant allocate a new Message Data descriptor. When pv_no_MD is true, the factory methods fail.
Class Fw_Message Framework Message. Provides an abstraction for a complete message, and a get/put recycling factory. Fw_Message objectss can be written to and read from. Fw_Message objects are implemented as a list of Fw_MDs. (see Fw_MD). See also Fw_Transfer_EH_User and NSDEFw_GFS. API Methods Fw_Message( void ); Constructor for an empty message. Note that the preferred method for obtaining an Fw_Message is get_message; ~Fw_Message(); Destructor. Deletes any associated Fw_MDs.
Returns the number of bytes that have been consumed from the Fw_Message. The original value is zero. void begin_read( void ); Prepares an Fw_Message for consumption by the read and skip_read methods. Note that begin_read must be called prior to the first call to read or skip_read. void read( char *pp_sink, const unsigned long pv_count ); Attempts to copy pv_count bytes from the list of Fw_MDs in the Fw_Message to the location pointed to by pp_sink.
Fw_Message::DEFAULT_BUFFER_SIZE. void write( char *pp_source, const unsigned long pv_count ); Transfers pv_count bytes from pp_source into the Fw_Message, starting after the last logical data byte in the Fw_Message. This is accomplished by calling write on the current write Fw_MD. If the Fw_MD is full, a new Fw_MD is obtained, added to the list in the Fw_Message, and made the current write Fw_MD. This is repeated until pv_count bytes have been transferred. iv_size is incremented by pv_count.
enum { MIN_BUFFER_SIZE } The minimum size of physical buffers allowed by the ORB. sockeh.h Classes The topics that follow describe the various classes declared in the sockeh.h header file ($NSD_ROOT/include/nsdevent/sockeh.h). Class Fw_Sock_Address API Methods Fw_Sock_Address() Creates an Fw_Sock_Address object. ~Fw_Sock_Address() Destructor for the current Fw_Sock_Address object. static unsigned hash( const Fw_Sock_Address &pr_address ) Rogue Wave dictionary-compatible hash method.
client event handler succeeded in initiating the connect protocol. If connect returns true, the client event-handler user should expect to be called with either theconnected or connect_failed method. void disconnect() Directs the event handler to terminate its connection. static EH* get_EH() Factory. Fw_Sock *get_ip_socket() Returns the IP socket. void put_EH( Fw_Sock_Client_EH *pp_EH ) Recycler. void send_message( Fw_Message *pp_msg ) Directs the event handler to deliver a full message over its connection.

exception could be a process in the server role received a request targeted for a transactional object, but the ORB was unable to find the OTS runtime component responsible for processing the service context. The client receives the exception returned from the server. In that case, it could be that the process was not properly linked with the OTS runtime library (nsdots.o) or that there is a memory corruption problem in the application or the ORB. Ensure the Makefile for the application includes nsdots.
1803 - 1314064139 - MINOR_DUPLICATE_REPOID This minor code occurs in the context of an INTF_REPOS system exception.

Common Error Messages (Error numbers 1000 1099) 1001 - ZDOM-GEN-ERR-NO-MEMORY User Action: During ORB initialization, access to the NSDCFGDB configuration database is initiated. If an internal database object can not be instantiated, a no memory message is posted. This message might indicate a corrupt database. 1002 - ZDOM-GEN-ERR-CONFIG User Action: During ORB initialization, access to the NSDCFGDB configuration database is initiated.
User Action : Five attempts have been made to open a database named name with unsuccessful results. Check the name, permissions and filecode (the filecode type should be 426). 1212 - Attempted delete of database failed: Delete for database failed: name User Action: Unable to delete the requested database. Check the database permissions or the number of existing opens for the database.
User Action: This error occurs during direct tcp_server initialization if the profile@ORB{host_name} key can't be retrieved from the configuration database. Verify that the server has the correct NSDOM_CFG_DBM environment; verify that the server should be configured as a direct tcp_server (as opposed to USE_COMM_SERVER), verify that the configuration database contains a valid profile@ORB{host_name} key and value. 1604 -Configuration error.
1613 - Expected null for object key name User Action: This error is generated when a POA is creating an object reference if the proxy's object key is not null. 1614 - GIOP Proxy marshalling 0 profiles User Action: This error occurs during the marshalling of an object reference, either as part of object_to_string or generating the response data for an out param or result, and there are no protocols enabled. Verify that the profile used with the process is present in the configuration database.
