Turns on or off compression of the synchronization stream between the MobiLink server and MobiLink clients.


compression= { zlib | none }

Support notes

For UltraLite, compression is off by default.

For dbmlsync, zlib compression is used by default.

In SQL Anywhere clients, if you turn off compression the data is completely unobfuscated; if security is an issue, you should encrypt the stream.

See Transport-Layer Security.


When you use zlib compression, you can configure the upload and download compression using the zlib_download_window_size option and zlib_upload_window_size option. Using these options, you can also turn off compression for either the upload or the download.

To use zlib compression in UltraLite, an application must call ULEnableZlibSyncCompression( sqlca ) and mlczlib10.dll must be deployed.
