Operating Systems AIX AIX 5.3, TL6 problem?? Post 302223002 by bakunin on Friday 8th of August 2008 05:37:43 AM

hmmm

an "efix" is an "emergency fix" in AIX. That is: someome reports a bug in the OS to IBM. If they recognize that its really their fault (not misconfiguration, misuse, etc.) they create an "APAR". I can't remember what the acronym means, the "P" stands for "problem", but basically it says "we officially declare having a bug".

Only then someone creates a fix for this, which results in a downloadable package (the "IY...."-files). Many of these packages bound together and repackaged make a "maintenance level" or "technical level", which is basically the same.

Where do the efixes come in? When a package is created it has to be thoroughly tested with all the other software parts of the OS because of possible interdependencies. Therefore it takes some time before such a IY-file is finished. If one doesnt have that much time IBM creates an "efix": a quick patch, which will hopefully correct the bug but nothing more. It might even create more problems as it solves. Plus: the package it corrects cannot be updated in a normal way any more. The efix has to be removed before updating it. (In the lslpp otput it has status "EFIX-LOCKED".) Additionally efixes are mutually exclusive: it might well be that several efixes for the same package exist but yo can install only one or the other, not two or more.

Bottom line: If you need an efix on top of TL6, why haven't you installed TL7 or even TL8 instead, which probably would correct the problem - without having to resort to efixes? Efixes are something one installs as an absolute last effort. Its not just another kind of update.

I hope this helps.

apport-cli

apport-cli(1)						      General Commands Manual						     apport-cli(1)

NAME

       apport-cli - Command line client for reporting problems

SYNOPSIS

       apport-cli

       apport-cli -c report

       apport-cli -f -p package

       apport-cli -f -P pid

DESCRIPTION

       apport automatically collects data from crashed processes and compiles a problem report in /var/crash/. This is a command line frontend for
       reporting those crashes to the developers. It can also be used to report bugs about packages or running processes.

       For desktop systems with a graphical user interface, you should consider installing the GTK or Qt user interface (apport-gtk or apport-qt).
       apport-cli is mainly intended to be used on servers.

       When  called  without  any  options,  it processes the pending crash reports and offers to report them one by one. You can also display the
       entire report to see what is sent to the software developers.

OPTIONS

       -c report, --crash-file=report
	      Instead of walking over the new crash reports in /var/crash/, report a particular report in an arbitrary	file  location.   This	is
	      useful for copying a crash report to a machine with internet connection and reporting it from there.

       -f, --file-bug
	      Report a (non-crash) problem. Requires specifying --package or --pid.  This will automatically attach information about your operat-
	      ing sytem and the package version etc. to the bug report, so that the developers have some important context.

       -p package, --package=package
	      When being used in --file-bug mode, specify the package to report the problem against.

       -P pid, --pid=pid
	      When being used in --file-bug mode, specify the PID (process ID) of a running program to report the problem  against.  This  can	be
	      determined with e. g.  ps -ux.

ENVIRONMENT

       APPORT_IGNORE_OBSOLETE_PACKAGES
	      Apport  refuses  to  create  bug	reports if the package or any dependency is not current. If this environment variable is set, this
	      check is waived. Experts who will thoroughly check the situation before filing a bug report can define this in  their  ~/.bashrc	or
	      temporarily when calling the apport frontend (-cli, -gtk, or -qt).
