3.1.4.4 Setting Up the Operating System

This section describes how to setup the Operating System.

IPC Resource Settings

Shunsaku uses the System V IPC resources provided by the operating system for communications between the different processes that make up Shunsaku. IPC resources must be set up according to the definitions for the Shunsaku operating environment to successfully run Shunsaku.

The following IPC resource settings are required to run Shunsaku:

• Shared Memory Resources
• Semaphore Resources

These settings are made using the kernel configuration file (/etc/sysctl.conf).

The parameter values in the tables below are required to run Shunsaku.

If values have already been set in the kernel configuration file, check these values and add or change them as required.

If no values are set in the kernel configuration file, the operating system's default values will be used, so add or change these default values as required.

For the parameters indicated as 'max' in the following explanation, set a larger value than the existing value (the default value or the value that has already been set). For parameters indicated as 'add', add the value given in the 'Value' column to the existing value.

After editing the kernel configuration file, either restart the system or execute "sysctl -p /etc/sysctl.conf".

Shared Memory Resources

Set the following values for shared memory resources.

Kernel parameter name	Value	Remarks
kernel.shmmax	1048576 or more	max
kernel.shmmni	The number of searchers that will run simultaneously	add

Semaphore Resources

Set the following values for semaphore resources.

Entry Format

kernel.sem = para1 para2 para3 para4

Set the following values for para1, para2, para3, and para4.

Kernel parameter name	Value	Remarks
para1(*1)	1 or more	max
para2	The number of searchers that will run simultaneously 10	add
para3(*1)	1 or more	max
para4	The number of searchers that will run simultaneously 10	add

*1) When setting para1 and para3, set a value that is equal to or greater than the default value for the operating system.
