Tables/Indexes

Here are some scripts related to Tables/Indexes .

Tabs w/ Questionable Inds

TABLES WITH QUESTIONABLE INDEX(ES) NOTES:

Owner - Owner of the table

Table Name - Name of the table

Column - Name of the column in question

The above query shows all tables that have more than one index with the same leading column. These indexes can cause queries to use an inappropriate indexes; in other words, Oracle will use the index that was created most recently if two indexes are of equal ranking. This can cause different indexes to be used from one environment to the next (e.g., from DEV to TEST to PROD).

The information does not automatically indicate that an index is incorrect; however, you may need to justify the existence of each of the indexes above.

select  TABLE_OWNER,
 TABLE_NAME,
 COLUMN_NAME
from   dba_ind_columns 
where   COLUMN_POSITION=1
and   TABLE_OWNER not in ('SYS','SYSTEM')
group   by TABLE_OWNER, TABLE_NAME, COLUMN_NAME
having  count(*) > 1

It is highly recommended that an index be created if the Foreign Key column is used in joining, or often used in a WHERE clause. Otherwise a table level lock will be placed on the parent table.

Segment Fragmentation

OBJECTS WITH MORE THAN 50% OF MAXEXTENTS NOTES:

Owner - Owner of the object

Tablespace Name - Name of the tablespace

Segment Name - Name of the segment

Segment Type - Type of segment

Size - Size of the object (bytes)

Extents - Current number of extents

Max Extents - Maximum extents for the segment

Percentage - Percentage of extents in use

As of v7.3.4, you can set MAXEXTENTS=UNLIMITED to avoid ORA-01631: max # extents (%s) reached in table $s.%s.

To calculate the MAXEXTENTS value on versions < 7.3.4 use the following equation: DBBLOCKSIZE / 16 - 7

Here are the MAXEXTENTS for common blocksizes: 1K=57, 2K=121, 4K=249, 8K=505, and 16K=1017

Multiple extents in and of themselves aren't bad. However, if you also have chained rows, this can hurt performance.

select  OWNER,
 TABLESPACE_NAME,
 SEGMENT_NAME,
 SEGMENT_TYPE,
 BYTES,
 EXTENTS,
 MAX_EXTENTS,
 (EXTENTS/MAX_EXTENTS)*100 percentage
from  dba_segments
where  SEGMENT_TYPE in ('TABLE','INDEX')
and  EXTENTS > MAX_EXTENTS/2
order  by (EXTENTS/MAX_EXTENTS) desc

Extents reaching maximum

TABLES AND EXTENTS WITHIN 3 EXTENTS OF MAXIMUM :

Owner - Owner of the segment

Segment Name - Name of the segment

select owner "Owner",
       segment_name "Segment Name",
       segment_type "Type",
       tablespace_name "Tablespace",
       extents "Ext",
       max_extents "Max"
from dba_segments
where ((max_extents - extents) <= 3) 
and owner not in ('SYS','SYSTEM')
order by owner, segment_name

Analyzed Tables

ANALYZED TABLE NOTES:

Owner - Owner of the table

Analyzed - Number of analyzed tables

Not Analyzed - Number of tables that have not be analyzed

Total - Total number of tables owned by user

The ANALYZE statement allows you to validate and compute statistics for an index, table, or cluster. These statistics are used by the cost-based optimizer when it calculates the most efficient plan for retrieval. In addition to its role in statement optimization, ANALYZE also helps in validating object structures and in managing space in your system. You can choose the following operations: COMPUTER, ESTIMATE, and DELETE. Early version of Oracle7 produced unpredicatable results when the ESTIMATE operation was used. It is best to compute your statistics.

A COMPUTE will cause a table-level lock to be placed on the table during the operation.

select OWNER,
 sum(decode(nvl(NUM_ROWS,9999), 9999,0,1)) analyzed,
 sum(decode(nvl(NUM_ROWS,9999), 9999,1,0)) not_analyzed,
 count(TABLE_NAME) total
from  dba_tables
where  OWNER not in ('SYS', 'SYSTEM')
group  by OWNER

Recently Analyzed Tables

LAST ANALYZED TABLE NOTES:

Owner - Owner of the table

Table Name - Name of the table

Last Analyzed - Last analyzed date/time

select  OWNER,
 TABLE_NAME,
 to_char(LAST_ANALYZED,'MM/DD/YYYY HH24:MI:SS') last_analyzed
from  dba_tab_columns
where  OWNER not in ('SYS','SYSTEM')
and  LAST_ANALYZED is not null
and COLUMN_ID=1
and  (SYSDATE-LAST_ANALYZED) < 30
order by (SYSDATE-LAST_ANALYZED)

Cached Tables

CACHED TABLE NOTES:

Owner - Owner of the table

Table Name - Name of the table

Cache - Cached?

Oracle 7.1+ provides a mechanism for caching table in the buffer cache. Caching tables will speed up data access and improve performance by finding the data in memory and avoiding disk reads.

select  OWNER,
 TABLE_NAME,
 CACHE
from dba_tables
where OWNER not in ('SYS','SYSTEM')
and CACHE like '%Y'
order by OWNER,TABLE_NAME
