Change Assistant is a standalone application that enables you to assemble and organize the steps necessary to apply updates and fixes for PeopleSoft application maintenance updates as well as performing upgrades. Change Assistant automates many of the steps, but will prompt you and guide you through any manual steps with embedded documentation.
You use Change Assistant for these situations:
Applying maintenance packs, bundles, and individual updates related to PeopleSoft application maintenance. Maintenance packs, bundles, and updates all come in the form of change packages.
Performing upgrades, which includes PeopleTools-only upgrades, PeopleSoft application-only upgrades, and combined PeopleTools and application upgrades.
Note: You do not use Change Assistant to apply PeopleTools patches.
Note: You use Change Assistant to apply updates that have a .ZIP extension. You do not use Change Assistant to apply updates that have an .EXE extension.
In order to perform reliable and accurate updates, Change Assistant gathers all the necessary information including the change log from the Environment Management hub and uploads it to Oracle. With the environment data available, Oracle can determine what updates apply to your environment.
You can obtain a list of all updates that have not been applied for a given application environment including all prerequisites. You can then download a set of change packages associated with the update IDs and install the patches and fixes with minimal effort.
Understanding Change Assistant Versions
You can use a newer version of Change Assistant than the version of PeopleTools you are using. However, the environment management agents and hub must be at the same version level as Change Assistant.
For example, your PeopleTools version could be at 8.53.09, but you can run Change Assistant at the 8.53.14 level as long as the agents and hub are also at the 8.53.14 level.
Maintaining Change Assistant
Periodically, Oracle provides patches for PeopleTools that supply fixes to critical defects. With each PeopleTools patch version, Oracle provides the following updates in executable format:
For example, 85014.exe
Contains all current fixes to the entire PeopleTools product, including those fixes to the software update technology, which includes Change Assistant and all environment management elements (agents, hub, and so on).
For example, 85014-PSCA.exe
Contains only the current fixes to apply to the software update technology, which includes Change Assistant and all environment management elements (agents, hub, and so on).
The software update technology runs independently from the rest of PeopleTools.
Note: If you install a complete PeopleTools patch, you do not need to apply the -PSCA patch individually. Apply the -PSCA patch individually only if you are interested in just the fixes for the software update tools and not the fixes for the entire PeopleTools product.
The -PSCA patch enables you to apply only the latest fixes to Change Assistant and the environment management framework without applying the latest full PeopleTools patch. By doing so, you can avoid the regression testing that typically occurs after applying a full PeopleTools patch.
