<para>

At least as of version 5.1, it should not be necessary to do

any special configuration for such parameters as

<varname>SHMMAX</varname>, as it appears this is configured to

allow all memory to be used as shared memory. That is the

sort of configuration commonly used for other databases such

as <application>DB/2</application>.</para>

<para> It may, however, be necessary to modify the global

<command>ulimit</command> information in

<filename>/etc/security/limits</filename>, as the default hard

limits for filesizes (<varname>fsize</varname>) and numbers of

files (<varname>nofiles</varname>) may be too low.
