Troubleshooting: Silent installation on AIX fails due to insufficient space reported in the /tmp directory

Silent installation on the AIX platform fails due to the report of insufficient space in the /tmp directory when the setup_aix script is run.

Problem

Installation fails when setup_aix is run and reports that there is insufficient space in the /tmp directory. This error can occur even when there is ample space available. This problem occurs when the installer is not able to correctly invoke OS-specific APIs to detect free space in the /tmp directory due to permission issues.

Solution

Run setup_aix with the -is:tempdir /other/temp/path parameter, specifying another temporary directory to use.

For example,
setup_aix -silent -options /pkg/products/commerce/response/WC7_Custom.response -is:tempdir /apps/temp/temp
