Syntax:
emgr -Xe <package name>

When you install an ifix, the following occurs:

A check is made to ensure that the filesets that are affected by the ifix are not already locked by an ifix that’s already installed.
A check is made to ensure that the appropriate fileset requisites are installed on the system.
A check is made to ensure that there is enough filesystem space on the system to install the ifix.
Any files that are to be replaced by the ifix are saved.
The files that the ifix delivers are copied into place on the system.
The filesets that are affected by the ifix are put into a LOCKED state to prevent further manipulation of the fileset. The fileset will be unlocked when the ifix is removed.
The system’s boot image is rebuilt, if necessary, and a message is displayed indicating that the system should be rebooted. The system will not be rebooted automatically.
