PreDownLoadVersion

String

Not specified

Purpose

The PreDownLoadVersion parameter specifies the current version of pre-download files and directories located in the predownload subdirectory of the specified DownLoadDirectory directory of the [environment-type] section for the presentation client environment (that is, for the specific environment identified by the hardware type, vendor, operating system version, and the ANSI or Unicode file type).

The PreDownLoadVersion parameter specifies a user-defined string of up to 60 characters. (Any additional characters are ignored in the version comparison.) The version specified in this parameter is case‑insensitive.

As you must change the string specified in this parameter to cause a new version of software to be pre‑downloaded, your site should adopt a convention that increments this value in some way so that it generates a totally new value for each release.

When the software release for pre-downloaded files is installed on the application server, copy the contents of the pre-download directories to the corresponding download directories on that application server and set the DownLoadVersion parameter in the [JadeAppServer] section to the value of the PreDownLoadVersion parameter. Each presentation client recognizes that a version change has occurred, determines that it already has the files downloaded, and then installs them.
