Setting synchronization parameters

The synchronization streams for UltraLite Java applications are objects, and are set by their constructors. The available streams are as follows:

UlSocketStream TCP/IP synchronization
UlSecureSocketStream TCP/IP synchronization with Certicom elliptic-curve transport-layer security.
UlSecureRSASocketStream TCP/IP synchronization with Certicom RSA transport-layer security.
UlHTTPStream HTTP synchronization.
UlHTTPSStream HTTPS synchronization.

The following line sets the stream to TCP/IP:

synch_opts.setStream( new UlSocketStream() );

For more information, see Synchronization parameters.

Separately-licensable option required

Use of UlHTTPSStream, UlSecureSocketStream and UlSecureRSASocketStream require Certicom technology, which in turn requires that you obtain the separately-licensable SQL Anywhere Studio security option and is subject to export regulations. For more information on this option, see Welcome to SQL Anywhere Studio.

For information on the individual parameters, see Synchronization stream parameters.

Once you have initialized the synchronization parameters, and set them to the values needed for your application, you can initiate synchronization using the JdbcConnection.synchronize() method.

The method takes a UlSynchOptions object as argument. The set of calls needed to synchronize is as follows:

UlSynchOptions opts = new UlSynchOptions;
opts.setUserName( "50" );
opts.setScriptVersion( "default" );
opts.setStream( new UlSocketStream() );
opts.setStreamParms( "host=123.45.678.90" );
conn.synchronize( opts );
