If you are not currently connected to the consolidated database (cons), run the following command:

dbisql -c "SERVER=cons;DBN=cons;UID=DBA;PWD=sql"

Execute the following statements on the consolidated database (cons) to add additional sample data to the employees table:

INSERT INTO employees (first_name, last_name) VALUES ('Javier', 'Spoor');
COMMIT;

Execute the following statements on the remote database (rem) to add additional sample data to the employees table:

INSERT INTO employees (first_name, last_name) VALUES ('Nelson', 'Kreitzer');
COMMIT;

At the consolidated database (cons), run the Message Agent:

dbremote -c "SERVER=cons;DBN=cons;UID=DBA;PWD=sql" -qc -v -o c:\tutorial\cons1.txt

This scans the transaction log of the consolidated database (cons) and generates a message for the remote database (rem) using the FILE message system. Since the debug message system parameter has been set for the FILE message system in the consolidated database, you can look at the c:\tutorial\cons1.txt file and verify that you see debug messages indicating that messages are being written to the c:\tutorial\messages\rem directory. For example:

I. 2011-03-25 11:03:31. Processing transactions from active transaction log
I. 2011-03-25 11:03:31. Sending message to "rem" (0-0000000000-0000550994-0)
I. 2011-03-25 11:03:31. sopen "c:\tutorial\messages\rem\cons.0"
I. 2011-03-25 11:03:31. write " c:\tutorial\messages\rem\cons.0"
I. 2011-03-25 11:03:31. close " c:\tutorial\messages\rem\cons.0"

At the remote database (rem) run the Message Agent:

dbremote -c "SERVER=rem;DBN=rem;UID=DBA;PWD=sql" -qc -v -o c:\tutorial\rem.txt

Using the HTTP message system, this command receives and applies the message that was just generated by the consolidated database. It then scans the transaction log and sends a message back to the consolidated database with the new row that was added in the remote database. Since the debug message system parameter has been set for the HTTP message system in the remote database, you can look at the c:\tutorial\rem.txt file and verify that you see debug messages indicating that the HTTP message system is being used. For example:

I. 2011-03-25 11:10:02. Sending message to "cons" (0-0000000000-0000557411-0)
I. 2011-03-25 11:10:02. HTTPWriteMessage "rem.0"
I. 2011-03-25 11:10:02. HTTPWriteMessage: success -- filename  "rem.0"
I. 2011-03-25 11:10:02. HTTPDisconnect

At the consolidated database (cons) run the Message Agent:

dbremote -c "SERVER=cons;DBN=cons;UID=DBA;PWD=sql" -qc -v -o c:\tutorial\cons2.txt

This command receives and applies the message that was just generated by the remote database using the FILE-based message system.

To verify that the consolidated database contains all four rows of data, execute the following statement to view the contents of the employees table:

 SELECT * FROM employees

The query returns the following data from the employees table, although the hire_date column contains the time you inserted the row, and not the values you see in the following table:

Verify that the remote database (rem) contains all four rows of data by executing the following statement to view the contents of the employees table:
