Changes to system printer files and other IBM-supplied objects
Release to release considerations for possible changes to system printer files and other IBM-supplied objects
The MAXRCDS parameter for QSYSPRT and QPSAVOBJ printer device files has always defaulted to 100000. During an upgrade, the default value has not changed for system printer files. Customization of IBM-supplied printer files is lost on a release upgrade. To preserve those changes, you need to rerun your changes to printer system files each release.
Changes to many types of IBM-supplied objects are lost during an upgrade because the copy of the object in the IBM product library is replaced by the new copy of the object.
