Oracle9i Installation Guide Release 2 (9.2.0.1.0) for UNIX Systems: AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, and Sun Solaris
2-20 Installation Guide
Perform the following steps to modify the kernel parameters by using the /proc file system. 1. Log in as the root user. 2. Change to the /proc/sys/kernel directory. 3. Review the current semaphore parameter values in the sem file by using the cat or more utility. For example, using the cat utility, enter the following command: # cat sem The output lists, in order, the values for the SEMMSL, SEMMNS, SEMOPM, and SEMMNI parameters. The following example shows how the output appears: 250 32000 32 128 In the preceding output example, 250 is the value of the SEMMSL parameter, 32000 is the value of the SEMMNS parameter, 32 is the value of the SEMOPM parameter, and 128 is the value of the SEMMNI parameter. 4. Modify the parameter values by using the following command syntax: # echo SEMMSL_value SEMMNS_value SEMOPM_value SEMMNI_value > sem Replace the parameter variables with the values for your system in the order that they are entered in the preceding example. For example: # echo 100 32000 100 100 > sem 5. Review the current shared memory parameters by using the cat or more utility. For example, using the cat utility, enter the following command: # cat shared_memory_parameter In the preceding example, the variable shared_memory_parameter is either the SHMMAX or SHMMNI parameter. The parameter name must be entered in lowercase letters. 6. Modify the shared memory parameter by using the echo utility. For example, to modify the SHMMAX parameter, enter the following command: # echo 2147483648 > shmmax 7. Modify the shared memory parameter by using the echo utility. For example, to modify the SHMMNI parameter, enter the following command: Setup Tasks to Perform as root User # echo 4096 > shmmni 8. Modify the shared memory parameter by using the echo utility. For example, to modify the SHMALL parameter, enter the following command: # echo 2097152 > shmall 9. Write a script to initialize these values during system startup, and include the script in your system init files. 10. Set the File Handles by using ulimit -n and /proc/sys/fs/file-max. # echo 65536 > /proc/sys/fs/file-max ulimit -n 65536 11. Set the Sockets to /proc/sys/net/ipv4/ip_local_port_range # echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_change 12. Set the Process limit by using ulimit -u. This will give you the number of processes per user. ulimit -u 16384 The parameters in the following table are the minimum values required to run Oracle9i with a single-database instance on Linux.
