Windchill System Administrator's Guide

Ensuring Proper Backup and Recovery
Maintaining Log Files
It is important that you either implement or request appropriate backup processes,
such as the following:
• In a production environment, Windchill's Oracle database should be backed
up on a regular basis. Oracle documentation provides additional information
about backup procedures.
• At the time of installation, the Windchill installation directory must be backed
up to preserve various configuration files.
• A given installation of Windchill and all source code should be backed up
each time the system is regenerated.
• The following Windchill directories should be backed up on a regular basis:
/db/sql, /codebase, and /src.
You do not have to back up the entire /codebase and /src directories each time.
However, you must back up the subdirectories containing Java packages that
have been changed at your site.
• The RetrievalWare windchill_indexes working directory should be backed up
on a regular basis. The RetrievalWare documentation provides additional
information about backup procedures.
• Depending upon the user authentication mechanism at your site, you may
need to ensure appropriate backup of files relevant to access control.
• Content files stored in an external file vault must be backed up using standard
operating system tools and procedures.
• The Aphelion Directory should be backed up on a regular basis. How often
you do this backup should be determined by how much activity is done in the
solution that relates to the LDAP entries stored in the directory. For example,
if user objects are stored in the directory, then you may want to back it up
more often than if only group and organization objects are stored there.
Windchill log files contain exception tracebacks and other information that can be
used for debugging code.
Each log file is enabled or disabled in the wt.properties file. If logging is enabled,
you will also need to determine the appropriate settings for related properties. For
example, the wt.name.log.append properties, which specify whether a log file is
appended to or overwritten when the associated application is started.
Log file names and locations are controlled by Windchill properties. The
$DATE(format) macro can be used to construct date-dependent file names. See
the Javadoc for the class wt.util.WTProperties for information about the $DATE
macro.
