Example of a Fragmented Database
The following example from the Doctor Report illustrates a fragmented database.
DNCS Database Check
============================================================
Total tempspace = 20520 pages ( 40.0 M)
Free tempspace = 20083 pages ( 39.2 M)
Database tempspace is at 2.2% used capacity.
Total dataspace = 2097150 pages ( 4095.9 M)
Free dataspace = 1919078 pages ( 3748.1 M)
OK: Database dataspace is at 8.5% used capacity.
Database Table Extents
============================================================

Explanation of the Doctor Report Output
The preceding example shows output from two headings of the Doctor Report:
DNCS Database Check and Database Table Extents. Notice that two of the tables
under the Database Table Extents heading consist of more than ten extents. The
emm and hct_profile tables consist of 161 and 65 extents, respectively. The system
operator of this database should take steps to defragment this database.

Note: Because system operators regularly load EMM CDs, the emm table is
especially subject to fragmentation.
