           Messaging Gateway Tibco Rendezvous Sample

This sample sets up a "round-trip" propagation to illustrate both
outbound (AQ->TIB/RV) and inbound (TIB/RV->AQ) propagation. An outbound 
propagation job moves messages from the AQ queue MGWUSER.MGW_BASIC_SRC 
to a TIB/RV subject. An inbound propagation job moves messages from the
same a TIB/RV subject to the AQ queue MGWUSER.MGW_BASIC_SRC. The end 
result should be messages moved from MGWUSER.MGW_BASIC_SRC to 
MGWUSER.MGW_BASIC_DEST.

Files 
----------
  create_users.sql
     Creates Oracle database users, MGWUSER, MGWAGENT, MGWADM needed for
     this sample

  create_queues.sql
     Creates AQ queues needed for this sample.

  tibrv_adm_setup.sql
     Configures Messaging Gateway objects for propagating messages.
     This file must be altered by the user before it can be run.

  setup.sql
     Allows setup of this sample to be accomplished in one step. It calls
     create_users.sql, create_queues.sql, tibrv_adm_setup.sql

  tibrv_adm_cleanup.sql
     Removes the Messaging Gateway configuration for this sample.

  drop_queues.sql
     Removes the AQ queues used for this sample.

  drop_users.sql
     Drops the Oracle database users used for this sample.

  enq_tibrv.sql
     Enqueues a fixed message into the AQ queue used as the source for
     message propagation.

  deq_tibrv.sql
     Dequeues a message from the AQ queue used as the destination for
     message propagation.


Configuring and running sample -- All files are SQL scripts
--------------------------------------------------------------
  1. Edit the script tibrv_adm_setup.sql (or a copy).
     There will be a block that looks as follows:
        --
        -- WARNING!!!! The values below must be set before this script is run.
        --
        begin
          :gv_database         := '';
          :gv_tibrv_subject    := NULL;
          :gv_tibrv_username   := NULL;
          :gv_tibrv_password   := NULL;
          :gv_tibrv_subject    := 'aqBridge';  -- aqBridge is the default
        end;

     Edit this block to include the appropriate values for these properties
     used for configuring a Messaging Gateway connection to Tib/Rendezvous. 

  2. As user, SYS as SYSDBA, run the script, setup.sql, to create the users
     MGWUSER, MGWAGENT, and MGWADM, create the AQ queues used by this sample,
     and configure Messaging Gateway objects for propagating messages.

  3. As user, MGWADM (password MGWADM), start the Messaging Gateway agent.

     e.g.  exec dbms_mgwadm.startup;

     Check the MGW_GATEWAY view and the log file (in ${ORACLE_HOME}/mgw/log) 
     to determine the status of the Messaging Gateway agent.

     e.g.  select agent_name, agent_status from MGW_GATEWAY;

  4. As user MGWUSER (password MGWUSER), enqueue a (fixed) message to the
     propagation source queue by running the script, enq_tibrv.sql.

  5. As a user MGWADM, check that the message has been propagated

     e.g.  select job_name, propagated_msgs, failures from MGW_JOBS;

     This will show the number of messages that have been propagated for
     each propagation job since the Messaging Gateway agent was started.

  6. Dequeue the message from the AQ queue by running the script deq_tibrv.sql 
     as MGWUSER. The script will return an error if no message is present.
     If a message is present it will be discarded.

Cleaning up the sample:
--------------------------------------------------------------
  1. As user MGWADM, before shutting down the Messaging Gateway agent, run
     the script, tibrv_adm_cleanup.sql, to clean up the MGW configuration.

  2. As user MGWADM, shut down the Messaging Gateway agent.

     e.g. exec dbms_mgwadm.shutdown

  3. When the Messaging Gateway agent is shut down, if desired, run the 
     script, drop_queues.sql, to remove all AQ queues created for this sample.

  4. Connect as SYS as SYSDBA and run drop_users.sql to remove Oracle 
     schemas created for this sample.
