- Delta Pack Overview
Delta Pack Overview
The Delta Pack bundles the binaries and libraries required for the Wrapper to run on all supported platforms*. It also contains the Windows bat files and Unix shell script used to launch the Wrapper. Use of these scripts make it easier to launch the Wrapper, as they will automatically select the appropriate binaries for the current platform. In other words, they let you launch the Wrapper in a transparent way, using the same commands across the different UNIX platforms (Windows using separate bat script files).
With a single configuration file, you will be able to configure the Wrapper to run your Java application either as a console application or as Windows Service/Unix Daemon on the different OSs. It is also possible to have a platform-specific configuration whenever the need arises.
Creating a single large distribution with the binaries of all platforms can make it much easier for your users to get up and running when they are not sure what they need. The resulting file is obviously large, but you are free to prune it down to only include what your users are likely to need. It is also possible to run a script after extraction to delete any files not needed for the current platform.
Even if you want to distribute your application in platform-specific bundles, the delta pack structure can be useful to include both 32 and 64-bit native files in a single distribution. This on its own is very useful so your users don't have to try and figure out what bits are needed for their specific combination of OS and Java installation.
The Delta Pack is available in all editions starting from Version 3.2.0.
* The z/OS platform uses the EBCDIC character set, which is not ASCII compatible. If you download the z/OS distribution and view it on other systems, all of its files will appear to be corrupted. This is normal. For this reason, the z/OS platform is intentionally not included in the delta pack distributions.
