Oracle Preinstallation RPM for Oracle Linux

Configure the Oracle Database with Oracle Preinstallation RPM for Oracle Linux. Subsequent updates.

Configure kernel parameters for Linux minimum parameter configuration for installation

At Oracle database installation, you can generate and run fixup scripts to check and set kernel parameters. This script is updated to the minimum value by updating the kernel parameters of the relevant requirements.

If you cannot use the fixup script, you can update it manually according to the following table:

Displaying and changing kernel parameter values

Use the commands in the following table to display the current kernel parameter values to determine which ones need to be changed. If you need to change, follow these steps:

1. Edit the/etc/sysctl.conf file to add or edit the relevant parameters as shown below

   fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmall = 2097152kernel.shmmax = 4294967295kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576

   Modifications are still valid for reboots. In SuSE Linux Enterprise Server Systems, the following command allows the system to read the/etc/sysctl.conf file when it restarts:

   # /sbin/chkconfig boot.sysctl on

2. Type the following command to change the current value of the kernel parameter:

   # /sbin/sysctl -p

   Check the output to verify that the parameter values are correct.

3. Type the command [/SBIN/SYSCTL-A] to confirm that the parameter values are correct.

4. Restart the system or use the command [sysctl-p] to make the settings effective.
