Hi,

Supercedes: These are patches that replace older patches. i.e. newer binary program library etc.

Dependencies: When some patches are intended to be loaded, there maybe other patches that need to be installed at the same time or be already be present on the system. If the files/patches are present installation will proceed. If they are included when you do the installation of your patch, installation will proceed. If they are not the installation will not proceed. The analysis phase of installing patches through the 'swinstall' program will do this analysis for you.

Dictionary meaning
Supersedes "1. replace something less efficient: to take the place or position of something that is less efficient, less modern, or less appropriate, or cause something to do this"

Dependences :"1. need for something: a need for something or somebody to be available in order to exist or survive financial dependence dependence on public transport"

In patch world supersedes means another newer release has come out and dependecies means you need to load its supporting pathes while load the main pathces.

hi,

Before installing any patch u need to check for supercedes and dependencies for that patch.

a supercede is the one which replaces the old patch with new enhancement in the functionality. u need to check is there any warnings associated with the supercede before installing it. after installation if issue command
swlist -l patch |grep
it will show superceded in the output.

for a patch there may be several dependencies, if u want to install such a patch all the dependencies must be installed. then only the new patch installation will be successful.
