Best Practices for Developing Applications

Observe best practices to help improve the success of software development for Sybase Unwired Platform.

• Check Network Connection Before Login
  If a device does not establish a network connection, the login process does not return a result until after a long timeout occurs. To avoid this delay, check the network connection before performing a login.
• Check Connection before Synchronization
  Before starting a synchronization, check the connection to the Unwired Server.
• Start a New Thread to Handle Replication-based Synchronization
  The synchronization process in replication-based synchronization may take a long time. To avoid blocking the user interface, start a new thread to do background work.
• Constructing Synchronization Parameters
  When constructing synchronization parameters to filter rows to be download to a device, if the SQL statement involves two mobile business objects, you must use an "in" clause rather than a "join" clause. Otherwise, when there is a joined SQL statement, all rows of the subsequent mobile business object are filtered out.
• Clear Synchronization Parameters
  When using synchronization parameters to retrieve data from an MBO during a synchronization session, clear the previous synchronization parameter values.
• Clear the Local Database
  Each time you redeploy a package on the Unwired Server, the client application should clear the local database. After clearing the database, login again so that the local database is reconstructed.
• Turn Off API Logger
  In production environments, turn off the API logger to improve performance.
