During the R19 Install, the Compare DB2 Objects step sets the following warnings:
Is there an automated function for the install process to invoke Reorgs
NO, there is no automated function in the install process.
These warnings are informing you that some ALTERs will be done placing these objects in AREO*. You'll have to reorg these objects (eventually), the job worked fine, and set warnings informing you of what's needed.
