Hi Lisa,
That'll teach you for using stuff written in 2002, especially when its based on
a script written
in 2001 :-)
Seriously though, I'd take a (very) thorough look at the driving select
statement. I put it
together like that because at the time I was at a client with tens of thousands
of segments so
queries to DBA_SEGMENTS just took forever, so I delved into the underlying view
definition to get
some speedup.
The DBA_SEGMENTS definition is one of those things that changes *very*
frequently (as our good
friends at Oracle add IOT's, compressed table, partitioned domain objects etc
etc etc etc etc).
The basic concepts within the script remain valid, but you might want to put
together a more
"version-robust" query to DBA_SEGMENTS/TABLES/INDEXES etc.
