This post is a bried recap of what we studied in “Software Management” in previous post.
Inside a bundle there are multiple softwares available in the form of package. These softwares are also called pre-requisites or dependencies.
So for a bundle to run, all these dependencies should be running.
There are 3 modes available for software installation:
In Applied mode, old configuration files of the software will be replaced by the new configuration files as the software is installed. But if the new installation does not work, admin can always perform a rollback from new to old configuration files.
In Reject mode, admin can reject the new configuration files of the software recently installed and revert back to the old version.
In Committed mode, permanent changes are made from old to new configuration files. No changes can be made once the software is installed in committed mode.
PTF stands for program temporary fix given by IBM to fix any problem.
e-fix is solution given by IBM to wait for 24 hours and resend the error if it again appears. The solution then sent is called APAR. APAR stands for authorized program analysis report.
In AIX OS, OS configuration files are installed in /usr.
Third party softwares are installed in /opt.
I’ll keep updating more on this topic in later posts.
