#1: If omitted, the system assumes the value of the PDUSER environment variable. If the PDUSER environment variable has not been specified, the system assumes the user name in the login window.
#2: By specifying the number of batch input/output pages, you can reduce the number of I/O operations, because data is input/output in units of specified pages in batch mode.
#3: If a space shortage occurs in an RDAREA during execution of pdrorg, you can complete the processing without having to expand the RDAREA temporarily (except for a table or index whose percentage of free space is 0).
