AIX Software Installation

After BOS installation you will be able to determine maintenance level.

The general syntax of the oslevel command is -

# oslevel [ -l Level | -g Level | -q ] [ -r ] [ -f ]

-l filesets earlier than the maintenance levels

-g filesets later than the current maintenance level.

-r  Applies all flags to Recommended Maintenance Levels

-f  Forces cache rebuilt

-q  Lists names of known maintenance levels, use with -l flag.

To show current maintenance level of system

# oslevel -r

O/p → 5300-03

Here 03 means maintenance level is 3.

Note:-Do not confuse this output with the M in V.R.M.F.

Software Installation:-

• Software can be installed in one of two states: applied or committed.
• The applied state places Software on the system. It retains the previous Version  of the Software.
• When an update is in the applied state Previous Version  is stored in the /usr/LPP/PackageName directory. This process is useful for deploying or testing new Software, where it may be necessary to go back to the previousVersion  of the Software in case of errors.
• The committed state places Software on the system and removes all previous levels of the Software from the /usr/LPP/PackageName directory
• If committed Software needs to be removed, you cannot go back to the previous Version  without a complete reinstall of the previous Version  Software.
• We recommend you install new Software in the applied state, rather than the committed state, until the newSoftware has been thoroughly tested.
• Sofware are installed by using installp command.

Command to install Software in an Applied State :-

# installp -a [ -eLogFile ] [ -V Number ] [ -dDevice ] { FilesetName [ Level ]… | -f ListFile | all }

 Command to install Software in an Commited State:-

installp -ac [ -N ] [ -eLogFile ] [ -V Number ] [ -dDevice ] { FilesetName [ Level ]… | -f ListFile | all }

For Example- To install all filesets within the bos.net Software Package in Applied State

# installp -avX  -d  /usr/sys/inst.images bos.net

To preview an install of all filesets within the bos.net Software Package in /usr/sys/inst.images directory in the Committed State

# installp -acpX  -d   /usr/sys/inst.images bos.net

# cat /var/adm/sw/installp.summary ( record of the installp output will found in this file)

Committing applied updates :-

For Example : To Commit all updates, type

# installp -cgX all

Rejecting applied updates :-

For Example-:, to reject all applied updates listed in the file ./reject.list, type

# installp -rBfX ./reject.list

Removing installed Software:-

For Example, to preview a remove of bos.net.ipsec.rte and its dependents, type

# installp -ugp -V2 bos.net.ipsec.rte

 Cleaning up after failed installations :-

For Example , to do cleanup of all fileset for reinstallation, type

# installp -C

Listing all installable Software on media :-

For example, to list the Software that is on your CD-ROM, type

# installp -L -d /dev/cd0

Software Installation Using Smit command:-

You all are now familiar with installpcommand for S/W installation but S/W’s installation can be done by using SMIT.

To install Software products:

# smitty install_latestspan>

INPUT DEVICE / directory for Software

SOFTWARE TO INSTALL → [_all_latest]

Committing applied updates :-

# smitty install_commit

SOFTWARE NAME → [all]

Rejecting applied updates :-

# smitty install_reject

SOFTWARE NAME → [] (Press F4 on the SOFTWARE name field to select the Software update you want to reject.)

Removing installed Software:-

# smitty install_remove

SOFTWARE NAME → [] ( Press F4 → Select the Software you want to remove by pressing F7, followed by Enter)
