When you plan to download Solaris components, such as patches, ensure that the following utilities are installed on the SDS machine:
/bin/tar
/usr/bin/unzip
/usr/bin/zipinfo
/usr/bin/file
/usr/bin/uncompress
/usr/bin/md5sum
If any of these utilities are missing, the download of Solaris patches might fail, although the error logs do not always indicate that a missing utility was the cause.
