Re: install 10g on SuSE 9.1 and got a error

Lyubomir Petrov



This error happens because of a new feature called Huge TLB support,
which is enabled by default in 2.6 kernels. By default only root has
permission to allocate shared memory with this option (SHM_HUGETLB) and
Oracle 10g defaults using it, so Oracle fails to allocate the SGA.

This capability is supposed to be able to controlled with the setcaps
program (CAP_IPC_LOCK), but I couldn't get it to work properly. I did
some research - the probable reason: setcap utilities are not supported
by the particular filesystem.

The solution is either to set DISABLE_HUGETLBFS=1 before you start
Oracle or to recompile the kernel without CONFIG_HUGETLB_PAGE and
CONFIG_HUGETLBFS configuration parameters.
