Shared memory segment: function not implemented

Question

Hi!
I tried to install Oracle8 on a dual pentium II / 233 system
running Suse 6.0 (kernel 2.2.1, glibc6)
Everything went fine, until I got the message
"Database creation failed, see logfile"
The logfile /u01/app/oracle/products/8.0.5/orainst/install.log
tells me the following:
- Entering database actions section.
- Creating initORCL.ora file
- Creating crdb2ORCL.sql database catalog and file creation
script
- ERROR: The 'CREATE DATABASE' statement for the ORCL
database failed.
egrep failed to find 'ORA-' error in the file:
/u01/app/oracle/admin/ORCL/create/crdbORCL.lst
/u01/app/oracle/admin/ORCL/create/crdORCL.lst tells me:
Connected.
ORA-27125: unable to create shared memory segment
Linux Error: 38: Function not implemented
create database "ORCL"
ORA-01034: ORACLE not available
Disconnected.
So, I guess it3s something wrong with the kernel. I did the
following:
changed in /usr/src/linux/include/asm/shmparam.h:
#define SHMIDX_BITS 16 (was 15)
#define SHMMNI 100 (was (1<<_SHM_ID_BITS)) #define SHMSEG
10 (was SHMSEG SHMMNI)
checked /usr/src/linux/include/linux/sem.h:
#define SEMMNI 128
#define SEMMSL 32
#define SEMMNS (SEMMNI*SEMMSL)
Compiled new kernel, rebooted, verified that the right kernel
was loaded, installed oracle new, but it still doesn3t work.
Have I missed anything ?
thanks

Hey, I ran into this problem too. Look and see if any db
processes failed to die last time you stopped oracle. I found a
ps_mon daemon still going when the database was down. I killed
it, restarted the database and everything was fine.
