1. nextext.sql
nextext.sql
To find tables that don't match the tablespace default for NEXT extent.
The implicit rule here is that every table in a given tablespace should
use the exact same value for NEXT, which should also be the tablespace's
default value for NEXT.
his tells us what the setting for NEXT is for these objects today.

SELECTsegment_name,segment_type,ds.next_extentasActual_Next
,dt.tablespace_name,dt.next_extentasDefault_Next

WHEREdt.tablespace_name=ds.tablespace_name
ANDdt.next_extent!=ds.next_extent
ANDds.owner=UPPER('&OWNER')
ORDERBYtablespace_name,segment_type,segment_name;
2. existext.sql
existext.sql
To check existing extents
This tells us how many of each object's extents differ in size from
the tablespace's default size. If this report shows a lot of different
sized extents, your free space is likely to become fragmented. If so,
this tablespace is a candidate for reorganizing.

3. No_pk.sql
no_pk.sql
To find tables without PK constraint
11/2/98
SELECTtable_name
FROMall_tables
WHEREwner='&OWNER'
MINUS
SELECTtable_name

11/30/98
SELECTowner,constraint_name,table_name,status
FROMall_constraints
WHEREwner='&OWNER'ANDstatus='DISABLED’ANDconstraint_type='P';
5. nonuPK.sql
nonuPK.sql
To find tables with nonunique PK indexes. Requires that PK names
follow a naming convention. An alternative query follows that
does not have this requirement, but runs more slowly.
11/2/98
SELECTindex_name,table_name,uniqueness
FROMall_indexes
