When you UNLOAD an entire HALDB database and the ran an RELOAD with PARTITION specified it result in a warning message "PARTITION KEYWORD INVALID"
Why does CA Database Organizer job fail?
The CA Database Organizer reload of a HALDB was designed to be driven by what is in the unload file. If it finds records for all the partitions, those partitions are cleared to empty and the records are reloaded in them. If it finds records for a subset of partitions, those partitions are cleared to empty and the records are reloaded into them.
The reload process is driven by the records found in the unload file. The PARTITION keyword has no effect on the reload process. The assumption is that one or more partitions were unloaded and those are the ones to be reloaded. If the entire database was unloaded, reload will use unload file and all the partitions will be reloaded.
RELOAD is combined with the keywords PARTITION and/or NUMBEROFPARTS, it will give a warning message “PARTITION KEYWORD INVALID” but did not change the Return Code.
