A. Daily Procedures

1. Free.sql

--

-- free.sql

--

-- To verify free space in tablespaces

-- Minimum amount of free space

-- d0cument your thresholds:

-- <tablespace_name> = <amount> m

--

SELECT tablespace_name, sum ( blocks ) as free_blk , trunc ( sum ( bytes ) / (1024*1024) ) as free_m

, max ( bytes ) / (1024) as big_chunk_k, count (*) as num_chunks

FROM dba_free_space

GROUP BY tablespace_name

2. Space.sql

--

-- space.sql

--

-- To check free, pct_free, and allocated space within a tablespace

--

-- 11/24/98

SELECT tablespace_name, largest_free_chunk

, nr_free_chunks, sum_alloc_blocks, sum_free_blocks

, to_char(100*sum_free_blocks/sum_alloc_blocks, '09.99') || '%'

AS pct_free

FROM ( SELECT tablespace_name

, sum(blocks) AS sum_alloc_blocks

FROM dba_data_files

GROUP BY tablespace_name

)

, ( SELECT tablespace_name AS fs_ts_name

, max(blocks) AS largest_free_chunk

, count(blocks) AS nr_free_chunks

, sum(blocks) AS sum_free_blocks

FROM dba_free_space

GROUP BY tablespace_name )

WHERE tablespace_name = fs_ts_name

3. analyze5pct.sql

--

-- analyze5pct.sql

--

-- To analyze tables and indexes quickly, using a 5% sample size

-- (do not use this script if you are performing the overnight

-- collection of volumetric data)

--

-- 11/30/98

BEGIN

dbms_utility.analyze_schema ( '&OWNER', 'ESTIMATE', NULL, 5 ) ;

END ;

/

4. nr_extents.sql

--

-- nr_extents.sql

--

-- To find out any object reaching <threshold>

-- extents, and manually upgrade it to allow unlimited

-- max_extents (thus only objects we *expect* to be big

-- are allowed to become big)

--

-- 11/30/98

SELECT e.owner, e.segment_type , e.segment_name , count(*) as nr_extents , s.max_extents

, to_char ( sum ( e.bytes ) / ( 1024 * 1024 ) , '999,999.90') as MB

FROM dba_extents e , dba_segments s

WHERE e.segment_name = s.segment_name

GROUP BY e.owner, e.segment_type , e.segment_name , s.max_extents

HAVING count(*) > &THRESHOLD

OR ( ( s.max_extents - count(*) ) < &&THRESHOLD )

ORDER BY count(*) desc

5. spacebound.sql

--

-- spacebound.sql

--

-- To identify space-bound objects. If all is well, no rows are returned.

-- If any space-bound objects are found, look at value of NEXT extent

-- size to figure out what happened.

-- Then use coalesce (alter tablespace <foo> coalesce;).

-- Lastly, add another datafile to the tablespace if needed.

--

-- 11/30/98

SELECT a.table_name, a.next_extent, a.tablespace_name

FROM all_tables a,

( SELECT tablespace_name, max(bytes) as big_chunk

FROM dba_free_space

GROUP BY tablespace_name ) f

WHERE f.tablespace_name = a.tablespace_name

AND a.next_extent > f.big_chunk

B. Nightly Procedures

1. mk_volfact.sql

--

-- mk_volfact.sql (only run this once to set it up; do not run it nightly!)

--

-- -- Table UTL_VOL_FACTS

CREATE TABLE utl_vol_facts

(

table_name VARCHAR2(30),

num_rows NUMBER,

meas_dt DATE

)

TABLESPACE platab

STORAGE (

INITIAL 128k

NEXT 128k

PCTINCREASE 0

MINEXTENTS 1

MAXEXTENTS unlimited

)

/

-- Public Synonym

CREATE PUBLIC SYNONYM utl_vol_facts FOR &OWNER..utl_vol_facts

/

-- Grants for UTL_VOL_FACTS

GRANT SELECT ON utl_vol_facts TO public

/

2. analyze_comp.sql

--

-- analyze_comp.sql

--

BEGIN

sys.dbms_utility.analyze_schema ( '&OWNER','COMPUTE');

END ;

/

3. pop_vol.sql

--

-- pop_vol.sql

--

insert into utl_vol_facts

select table_name

, NVL ( num_rows, 0) as num_rows

, trunc ( last_analyzed ) as meas_dt

from all_tables -- or just user_tables

where owner in ('&OWNER') -- or a comma-separated list of owners

/

C. Weekly Procedures

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.

--

-- This tells us what the setting for NEXT is for these objects today.

--

-- 11/30/98

SELECT segment_name, segment_type, ds.next_extent as Actual_Next

, dt.tablespace_name, dt.next_extent as Default_Next

FROM dba_tablespaces dt, dba_segments ds

WHERE dt.tablespace_name = ds.tablespace_name

AND dt.next_extent !=ds.next_extent

AND ds.owner = UPPER ( '&OWNER' )

ORDER BY tablespace_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.

--

-- 12/15/98

SELECT segment_name, segment_type

, count(*) as nr_exts

, sum ( DECODE ( dx.bytes,dt.next_extent,0,1) ) as nr_illsized_exts

, dt.tablespace_name, dt.next_extent as dflt_ext_size

AND dx.owner = '&OWNER'

GROUP BY segment_name, segment_type, dt.tablespace_name, dt.next_extent

3. No_pk.sql

--

--

-- To find tables without PK constraint

--

SELECT table_name

FROM all_tables

WHERE owner = '&OWNER'

MINUS

SELECT table_name

FROM all_constraints

4. disPK.sql

--

--

-- 11/30/98

SELECT owner, constraint_name, table_name, status

FROM all_constraints

WHERE owner = '&OWNER' AND status = 'DISABLED’ AND constraint_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

SELECT index_name, table_name, uniqueness

FROM all_indexes

WHERE index_name like '&PKNAME%'

AND owner = '&OWNER' AND uniqueness = 'NONUNIQUE'

SELECT c.constraint_name, i.tablespace_name, i.uniqueness

FROM all_constraints c , all_indexes i

OR next_extent != ( 256 * 1024 )

)

AND owner = '&OWNER'
