This lesson assumes you have completed all preceding lessons. See Lesson 1: Setting up a text file data source.
The dbmlsync utility initiates MobiLink synchronization for SQL Anywhere remote databases. Before starting dbmlsync, add order data and comments to your remote database.
Connect to the MobiLink client database from Interactive SQL, if you are not already connected, by running the following command:
dbisql -c "SERVER=remote1;UID=DBA;PWD=sql" |
Execute the following statement to add an order to the RemoteOrders table in the client database:
INSERT INTO RemoteOrders (order_id, product_id, quantity, order_status) VALUES (1,12312,10,'new'); |
Add a comment to the OrderComments table in the client database by executing the following statement in Interactive SQL:
INSERT INTO OrderComments (comment_id, order_id, order_comment) VALUES (1,1,'send promotional material with the order'); |
Execute the following statement in Interactive SQL to commit your changes:
COMMIT; |
Run the following command:
dbmlsync -c "SERVER=remote1;UID=DBA;PWD=sql" -e scn=on -o rem1.txt -v+ |
The following table contains a description for each dbmlsync option used in this lesson:
Option | Description |
---|---|
-c | Specifies the connection string. |
-e scn | Sets SendColumnNames to on. This behavior is required by direct row handling if you want to reference columns by name. |
-o | Specifies the message log file rem1.txt. |
-v+ | The -v option specifies what information is logged. Using -v+ sets maximum verbose logging. |
Once you have started the MobiLink synchronization client, an output screen appears indicating that the synchronization succeeded. The SQL-based synchronization transfers rows in the client's RemoteOrders table to the RemoteOrders table in the consolidated database.
Java or .NET processing inserted your comment in orderComments.txt.
Close any SQL Anywhere MobiLink client windows.
Insert a response in orderResponses.txt to download to the remote database. This action takes place on the server side.
Add the following text to orderResponses.txt. You must separate entries using the tab character. At the end of the line, press Enter.

Run synchronization using the dbmlsync client utility.
This action takes place on the client-side.
Run the following command:
dbmlsync -c "SERVER=remote1;UID=DBA;PWD=sql" -o rem1.txt -v+ -e scn=on |
The MobiLink client utility appears.
Rows downloaded using direct row handling are not printed by the mlsrv12 -v+ option, but are printed in the remote log by the remote -v+ option.
In Interactive SQL, select from the OrderComments table to verify that the row was downloaded.
Execute the following SQL statement:
SELECT OrderComments; |
