Windchill Software Maintenance and Best Practices
Normal maintenance corrections and updates to the products of Windchill 7.0 are
delivered primarily through a single cumulative installation image known as the
Windchill Service Pack. Updates to a smaller subset of the products are delivered
through a replacement CD image. Both the Windchill Service Pack and any
replacement CDs can be ordered in CD form or downloaded from the PTC
Software Update Web site (http://www.ptc.com/cs/doc/swupdate.htm). Each
release of maintenance is identified with its own datecode, which is clearly visible
from the Software Update Web site and through the installer programs. The
datecode values, which are always increasing, identify a version within the overall
7.0 release. Datecode values for maintenance releases are of the form Mnnn
where nnn is numeric, typically increasing by 10. Thus the first maintenance
release is M010, the second is M020, and so on. In the event that a high priority
problem must be delivered quickly, a temporary patch can be delivered in the
form of an executable JAR file that will deliver and install the updates. Temporary
patches are also uniquely identified, but not with a datecode value.
For many customers, part of implementing and deploying a Windchill solution
involves adding customizations and possibly modifying some files delivered by
PTC. Because some of the files changed by the site may also be updated in a
