<h1 class="topictitle1">Precompile SQL statements in a profile using the DB2 SQLJ profile
customizer, db2profc</h1>
<div><p>You can use the DB2<sup>®</sup> SQLJ Profile Customizer, db2profc, to make your Java™ application
work more efficiently with your database.</p>
<p>The DB2 SQLJ
Profile Customizer does the following:</p>
<ul><li>Precompiles the SQL statements that are stored in a profile and generates
a package in the DB2 database.</li>
<li>Customizes the SQLJ profile by replacing the SQL statements with references
to the associated statement in the package that was created.</li>
</ul>
<p>To precompile the SQL statements in a profile, type in the following at
the Qshell command prompt:</p>
<blockquote><pre>db2profc <em>MyClass_SJProfile0.ser</em></pre>
</blockquote>
<p>Where <em>MyClass_SJProfile0.ser</em> is the name of the profile you want
to precompile.</p>
<div class="section"><h4 class="sectiontitle">DB2 SQLJ
Profile Customizer usage and syntax</h4><p>db2profc[<em>options</em>] &lt;<em>SQLJ_profile_name</em>&gt;</p>
<p>Where <em>SQLJ_profile_name</em> is
the name of the profile to be printed and <em>options</em> is the list of options
you want.</p>
<p>The options available for db2profp are the following:</p>
<ul><li><samp class="codeph">-URL=&lt;<em>JDBC_URL</em>&gt;</samp></li>
<li><samp class="codeph">-user=&lt;<em>username</em>&gt;</samp></li>
<li><samp class="codeph">-password=&lt;<em>password</em>&gt;</samp></li>
<li><samp class="codeph">-package=&lt;<em>library_name/package_name</em>&gt;</samp></li>
<li><samp class="codeph">-commitctrl=&lt;<em>commitment_control</em>&gt;</samp></li>
<li><samp class="codeph">-datefmt=&lt;<em>date_format</em>&gt;</samp></li>
<li><samp class="codeph">-datesep=&lt;<em>date_separator</em>&gt;</samp></li>
<li><samp class="codeph">-timefmt=&lt;<em>time_format</em>&gt;</samp></li>
<li><samp class="codeph">-timesep=&lt;<em>time_separator</em>&gt;</samp></li>

<li><samp class="codeph">-sorttbl=&lt;<em>library_name/sort_sequence_table_name</em>&gt;</samp></li>
<li><samp class="codeph">-langID=&lt;<em>language_identifier</em>&gt;</samp></li>
</ul>
<p>The following are the descriptions of these options:</p>
<dl><dt class="dlterm"><samp class="codeph">-URL=&lt;<em>JDBC_URL</em>&gt;</samp></dt>
<dd>Where <em>JDBC_URL</em> is the URL of the JDBC connection. The syntax for
the URL is: <pre> "jdbc:db2:systemName"</pre>
For more information,
see <a href="jdbc.htm">Access your iSeries™ database with the IBM<sup>®</sup> Developer
Kit for Java JDBC driver</a>.</dd>
</dl>
<dl><dt class="dlterm"><samp class="codeph">-user=&lt;<em>username</em>&gt;</samp></dt>
<dd>Where <em>username</em> is your username. The default value is the user
ID of the current user that is signed on for local connection.</dd>
</dl>
<dl><dt class="dlterm"><samp class="codeph">-password=&lt;<em>password</em>&gt;</samp></dt>
<dd>Where <em>password</em> is your password. The default value is the password
of the current user that is signed on for local connection.</dd>
</dl>
<dl><dt class="dlterm"><samp class="codeph">-package=&lt;<em>library name/package name</em>&gt;</samp></dt>
<dd>Where <em>library name</em> is the library where the package is placed,
and <em>package name</em> is the name of the package to be generated. The default
library name is QUSRSYS. The default package name is generated from the name
of the profile. The maximum length for the package name is 10 characters.
Because the SQLJ profile name is always longer than 10 characters, the default
package name that is constructed is different from the profile name. The default
package name is constructed by concatenating the first letters of the profile
name with the profile key number. If the profile key number is greater than
10 characters long, then the last 10 characters of the profile key number
is used for the default package name. For example, the following chart shows
some profile names and their default package names:
