It is possible to have Developer Support enabled and not running. This still provides a measurable
performance hit because it registers a listener. Once enabled in enterprise.init and recognized
by the servlet container, you can turn Developer Support on and off via the administrator page. See
Section 7.3.2.2 Developer Support Features for more information on controlling Developer Support
via the administrator page.
7.3.2. Using Developer Support
7.3.2.1. Accessing Developer Support
To access Developer Support, login as a site-wide administrator and then navigate to /ds/ on your
server. For example, if your server is running on your localhost and your Dispatcher Servlet Path is
/ccm, then you would access Developer Support at http://localhost/ccm/ds/.
7.3.2.2. Developer Support Features
Once you have accessed Developer Support, you will find an index page listing up to the last 100
requests to the server as well as several options for configuring your server:
Request Information
Developer Support stores information about the last 100 requests to the server, accessible
through the index page. For each request, information such as the duration, the number of
database operations executed, the requesting IP address, and the URL requested is available.
This information is especially useful for performance-tuning. For example, if you are looking for
a slow or expensive page in a certain use case, look for a request with an unusually long duration
or large number of queries.
Click on a Request URL to find out detailed information about that individual request. The
Request Information page provides details such as the amount of time for various stages of the
request, and the text and duration of each SQL operation.
Click on a SQL Operation to find detailed information about that specific operation. The Query
Information page provides a stack trace showing the code that led to the SQL operation’s exe-
cution. Also, if the server is running on an appropriately configured Oracle database, the page
will provide a link to show the explain plan of the query.
Query Log
On the Developer Support index page, next to each request, is a link to a Query Log. A request’s
Query Log page presents a text page of all the SQL operations for that request, formatted for
easy cut-and-paste into a database client such as SQLPlus or PSQL.
Log4j Logger Adjuster
The Developer Support index page provides a link to a Log4j Logger Adjuster. This Log4j
adjuster allows the developer to change the server’s logging level at runtime. See also Section
7.5.1 Log4J
Disable Request Logging
The Disable Request Logging link on the Developer Support index page allows you to toggle
at runtime whether Developer Support actively stores information about each request. If you
disable request logging, Developer Support will clear all previously stored request information
as well as stop recording information about new requests.
