    altobj() housekeeping

    DB2 LUW 8.2 FP14 Red Hat AS 2.1

    I primarily use alter table (and therefore altobj()) from CC.

    Is it OK to delete those T* backup tables that get created when I alter
    tables w/ altobj()? It looks like sometimes they get left there and
    sometimes not?

    Is it OK to delete any rows that I see left around in
    SYSTOOLS.ALTOBJ _INFO?? If there are no alters happening, should
    SYSTOOLS.ALTOBJ _INFO be empty?

    altobj() does a LOAD COPY YES and apparently leaves stuff in
    ~/sqllib/tmp. Once a backup is done, is is safe to delete everything
    in ~/sqllib/tmp? Some of these files are named pipes?

    TIA
