Stephen,
what are we talking about in terms of files in a single directory
that total nearly 110GB? Is it one or two huge files? A hundred,
maybe a thousand, or more? What are the naming schemes? Always
the same or always predictable? Are there name extensions for
file types? If the numbers are reasonable you could create a
set of DLEs using include statements and a catch-all using
exclude statements.
For example, (assumptions include reasonable number of files,
say < 1000 but I'm not certain what is reasonable, most with names
beginning with lowercase letters but a few with digits or uppercase
and an ascii charset :)
host Ora-a2g /path/to/RMAN/backup/dir {
your_current_dumptype
include file ./[a-g]*
}
host Ora-h2s /path/to/RMAN/backup/dir {
your_current_dumptype
include file ./[h-s]*
}
host Ora-t2z /path/to/RMAN/backup/dir {
your_current_dumptype
include file ./[t-z]*
}
host Ora-rest /path/to/RMAN/backup/dir {
your_current_dumptype
exclude file ./[a-z]*
}
