SQL Anywhere 12.0.1 WhitePaper - Sybase

Advanced Data SynchronizationSQL Anywhere 12.0.1 also offers new improvements to MobiLink, SQL Anywhere’s feature rich datareplication and synchronization tool. The latest improvements to MobiLink offered in SQL Anywhere 12.0.1include: performance advancements, additional database support, and client enhancements.PerformanceThe MobiLink synchronization server monitors performance and automatically adjusts the number ofconcurrent database worker threads as necessary. This feature allows deployments to achieve betterthroughput with less load testing. Given a wide enough range when launching the synchronization server,MobiLink automatically finds the number of database worker threads providing the best throughput.Consolidated Database SupportThe MobiLink server now supports Sybase IQ as a consolidated database. To set up Sybase IQ to work as aMobiLink consolidated database, you must run a setup procedure that adds MobiLink system tables, storedprocedures, triggers, and views that are required for MobiLink synchronization.The MobiLink server on a Windows or Linux platform also supports consolidated databases running onSybase Adaptive Server Enterprise 15.5.Synchronization Client EnhancementsSQL Anywhere 12.0.1 has also integrated the following improvements to MobiLink Clients:• Automatic resumption of HTTP sessions ‐ When an HTTP connection is lost, MobiLink clientsautomatically attempt to reconnect to the MobiLink server and continue the synchronization.• DER encoded keys are now supported for end‐to‐end encryption• Support for public keys from x.509 certificates ‐ End‐to‐end encryption now supports public keysfrom x.509 certificates.Additional MobiLink EnhancementsThe MobiLink Agent for central administration of remote databases now supports two new variables fortask conditions {is_online} and {network_conn_name}. The variable {is_online} can be used to checkwhether the client device is connected to a network on which the MobiLink server of the agent can bereached. The variable {network_conn_name} evaluates to the name of the network connection that is usedby the Agent for communication with its MobiLink server.The MobiLink Agent can now be configured interactively on a remote device through a series ofconfiguration windows.MobiLink Relay Server has also received additional features. The Relay Server Outbound Enabler (RSOE), forexample, now supports HTTP authentication (Basic and Digest) against web servers and HTTP proxies. Thefollowing new (optional) network connection options have been added to the Outbound Enabler:• http_userid ‐ Userid for authentication.SQL Anywhere 12.0.1New Features Summary – February 2011
