Re: Oracle 8I installation on Intel based Sun solaries
Seems to me that linking of oracle has failed. Try command "which make" to ensure you got make in the right directory (can be linked). There's command "relink all" (at least in AIX Oracle 8.1.7) in $ORACLE_HOME/bin as I recall for relinking Oracle8. Also $TMP (default /tmp) < 75 MB can give you odd errors.
This can be a result of some missing operating system libraries/patches. Check if you have applied the required OS patches as mentioned in the installation guide.
Use the latest kernel patch from Sun Microsystems. Sun provides patch information at: http://sunsolve.sun.com
Solaris 2.6 requires at least kernel jumbo patch revision #105181-15 for successful installation of Release 3 (8.1.7)
