The documentation portal is undergoing maintenance. During this period, you can't create any new user credentials. If you do, you'll need to recreate the user credential after the maintenance period ends.
DB2 image copy access method (DB2390IMG) only. If the imagecopy data set is specified, PowerExchange checks that the imagecopy file exists and that a consistent imagecopy is selected. If either of these is not true, for example, the imagecopy file does not exist or it is inconsistent, then the request is rejected and a message is displayed.
This behavior can be overridden if required by supplying the parameter {DTLIMGOV=Y}. This enables inconsistent imagecopies to be read.
