dramatically better with lower machine stress over <function>db2_connect</function>. This
is a convenience override of <function>db2_connect</function> to evoke <function>db2_pconnect</function> without
PHP source code changes.

<listitem>
<para>
This option overrides i5 db2_(p)connect userid and password in the PHP
application. When <parameter>ibm_db2.i5_ignore_userid</parameter> = 1,
all db2 (p)connections become null userid and null password. Therefore
Apache jobs connect with the current profile (NOBODY). Use of this override
is only for simple DB2 based websites that never require profile switching
and therefore can avoid all overhead of server mode additional QSQSRVR jobs.
This is a convenience override of db2_(p)connect to set the userid and password
values to null without PHP source code changes. This override can be used in
combination with <parameter>ibm_db2.i5_all_pconnect</parameter> = 1.
