The MU3 can only be installed on a system that is running the Solaris 9 operating environment.
Space requirements for each file system vary, depending on the following:
Whether you select the -d option
The location of the backout directory when saving backout data
The disk partitions and the space that is available in each file system, relative to the patch disk space that is needed for each file system
Your system's locale
Whether some of the Maintenance Update patches are already installed on your system
The install_mu script performs a space analysis. The script reports the space that is needed for each file system, including backout space if applicable. The space calculations are completed in several minutes.
The install_mu script does not proceed if it determines that space is lacking in one or more file systems. The patch installation space that is needed is calculated with some precision. However, the backout data space need is estimated. The reported need might be higher than the actual need.
Run install_mu with the -f option if you meet both of the following conditions:
You know that you have enough disk space to apply the patch set and backout data if desired
If you are bypassing the space calculation
