YUM utilities on AIX

Transcription

1 YUM utilities on AIX yum-utils is a collection of utilities and plugins extending and supplementing yum in different ways. Since YUM is available on AIX, it is best to exploit the functionalities provides by yum-utils. If not already have installed yum, then run the yum.sh script for easy yum installation. utilities are the python scripts which are provided as a executable with yum-utils package. This document explains basic functionality of each individual utilities supported AIX with sample output. Please refer separate document on yum-plugins, to know more on yum plugins functionality. Not all options output are shown here, only most of the basic and important commands output are included. More information on commands can found using help option or refer the link provided in reference section. Not all utilities which are supported on other linux distributions are provided. Please Refer the section Unsupported utilities to know the list. To get the utilities, install yum-utils rpm package. Now lets start with each utilities supported on AIX. find repos of install: Shows from which repository a particular package came from. # find repos of install Error: AIX rpm ppc not found in any repository bash ppc from repo AIX_Toolbox ca certificates ppc from repo AIX_Toolbox curl ppc from repo AIX_Toolbox db ppc from repo AIX_Toolbox expat ppc from repo AIX_Toolbox Error: expect ppc not found in any repository gdb ppc from repo AIX_Toolbox_local autoconf noarch from repo AIX_Toolbox_noarch... needs restarting: Reports process ids that started running before components that they use were updated. For example, if a packages are updated after starting a daemon from the binary provided by a package then this list those processes. # needs restarting : /opt/freeware/sbin/smbd : /opt/freeware/sbin/smbd : /opt/freeware/sbin/nmbd : /opt/freeware/sbin/smbd : /opt/freeware/sbin/smbd repoquery: query yum repositories and get additional information on the them.

6 repo rss: generates an RSS feed from one or more Yum repositories. This command needs to have libxml2-python rpm installed. Due to bug in libxml2-python we might need to use LIBPATH as shown below. To create an rss feed for the AIX_Toolbox_local repository and store it as rss-toolbox-local.xml. # LIBPATH=/opt/freeware/lib:/usr/lib/:/lib repo rss f rss toolbox local.xml \ AIX_Toolbox_local Reading in repository metadata please wait... By default it generates rss for the most recent in 3 days. To change this need to use -r option. # LIBPATH=/opt/freeware/lib:/usr/lib/:/lib repo rss r 1 f rss toolbox local.xml \ AIX_Toolbox_local Reading in repository metadata please wait... repoclosure: reads metadata of repositories, checks dependencies and displays list of unresolved dependencies. # repoclosure Reading in repository metadata please wait...

For example We have installed the lower version of expat & expat-devel after creating dump file, hence it upgrades to the latest available versions. We have installed screen package after creating the dump file, hence tries to remove it. We removed grep package after creating the dump file, hence it tries to install it. Similarly, it should either upgrade or downgrade packages accordingly. We can also use filter-types option to either only install, remove, update, downgrade transactions. # yum debug restore /tmp/dd/yum_debug_dump pokndd _11:26:28.txt.gz Reading from: /tmp/dd/yum_debug_dump pokndd _11:26:28.txt.gz upgrade expat ppc upgrade expat devel ppc remove screen ppc install grep ppc Setting up Yum Shell Setting up Upgrade Process Setting up Remove Process Setting up Install Process > Package expat.ppc 0: will be updated > Package expat.ppc 0: will be an update > Package expat devel.ppc 0: will be updated > Package expat devel.ppc 0: will be an update > Package grep.ppc 0: will be installed > Package screen.ppc 0: will be erased > Finished Dependency Resolution Package Arch Version Repository Size Installing: grep ppc AIX_Toolbox 442 k Updating:
