03. Using Tar Balls - previously created from a running database and
04. Using Tar Balls - created for the new installations using 01 or 02 methods
Some are of the opinion that copying the bundle of binaries from one server to another is the installation. That is NOT true.
Windows maintain and Unix has soft and hard links
Purpose Windows Registry
The Windows Registry serves as an archive for collecting and storing the configuration settings of Windows components, installed hardware/software/application and more. A Windows component, hardware or a software, retrieves the registry entries or keys relating to it, every time it is started. It also modifies the registry entries or keys corresponding to it, in its course of execution. When keys are added to the registry, the data are sorted as computer-specific data or user-specific data in order to support multiple users.
Purpose Installation On Unix Server
When an application is Installed on Unix server.
01. runtime controls
02. soft links, if any
03. hard links, if any
04. configuration files under different conventional directory paths
05. and other activities including copying binaries
When a tar ball is created from under particular directory is created, the files created for application purposes will not be created. The soft links and hard links created on the source server may be part of the decompressing the tar ball, but, if the purpose of creating the destination server is different from the source server, the libraries may not have been pointing to those libraries. Run Time Controls will not be created. configuration files, if any, will NOT be created. and some other actions that are not simply copying the binaries from the tarfile, do not happen.
So, in the absence of the actions beyond copying the binaries by uncompressing the tarfile, the application may behave differently not as expected.
