Running a Hub Under Linux

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

The default Linux configuration may not be sufficient for running CodeSonar's PostgreSQL database.

If kernel.shmmax is lower than 134217728, or kernel.shmall is lower than 32768, you will need expand the shared memory. (If the settings are greater than or equal to these values, you don't need to change them.)

Create a file named /etc/sysctl.conf (if it does not already exist).

Edit /etc/sysctl.conf to contain the following variable assignments.

kernel.shmmax=134217728
kernel.shmall=32768

Save and close /etc/sysctl.conf

Reboot so that the changes can take effect.

If you are currently working through installation and hub setup, go on to C: Start The Hub.

Note

If you don't have access to /etc/sysctl.conf or don't want to make these settings permanent, use command line sysctl instead:

sysctl -w kernel.shmmax=134217728
sysctl -w kernel.shmall=32768
