During Oracle 10g installation on Solaris box,  I ran into following issue.

Performing check for Kernel
Checking kernel parameters
Checking for BIT_SIZE=64; found BIT_SIZE=64.    Passed
Checking for shmsys:shminfo_shmmax=4294967295; found no entry.  Failed <<<<
Checking for shmsys:shminfo_shmmni=100; found no entry. Failed <<<<
Checking for semsys:seminfo_semmni=100; found no entry. Failed <<<<
Checking for semsys:seminfo_semmsl=256; found no entry. Failed <<<<
Check complete. The overall result of this check is: Failed <<<<

Solution:

I had to increase shmmax to big value using prctl.  You will have to run as root privileged user.

prctl -n project.max-shm-memory -v 35gb -r -i project user.oracle
