Find objects size in MBytes (TABLES, INDEXES, PARTITIONS etc)

0


Summary

Finding object size in Oracle database is very important and common.
Is it very useful to know the exact size occupied by the object at the tablespace.
The object size in the following scripts is in Mbytes. The scripts have been formatted to work very easily .

For example you can filter with tablespace_name, or owner, or size (for example more than 1GByte)

SELECT owner, segment_name, segment_type, partition_name, ROUND(bytes/(1024*1024),2) SIZE_MB, tablespace_name
FROM DBA_SEGMENTS
WHERE SEGMENT_TYPE IN ('TABLE', 'TABLE PARTITION', 'TABLE SUBPARTITION',
'INDEX', 'INDEX PARTITION', 'INDEX SUBPARTITION', 'TEMPORARY', 'LOBINDEX', 'LOBSEGMENT', 'LOB PARTITION')
--AND TABLESPACE_NAME LIKE 'COSTE%'
--AND SEGMENT_NAME LIKE 'P2010201%'
--AND partition_name LIKE 'P20100201%'
--AND segment_type = 'TABLE'
--AND OWNER = 'TEST_POC'
--AND ROUND(bytes/(1024*1024),2) > 1000
ORDER BY bytes DESC;

You can group by tablespace, owner and segment type and see the total space occupied in MBytes
SELECT tablespace_name, owner, segment_type "Object Type",
       COUNT(owner) "Number of Objects",
       ROUND(SUM(bytes) / 1024 / 1024, 2) "Total Size in MB"
FROM   sys.dba_segments
WHERE  tablespace_name IN ('TEST')
GROUP BY tablespace_name, owner, segment_type
ORDER BY tablespace_name, owner, segment_type;

Summary


You know that you can define the size of each buffer pool in the buffer_cache as you like, but how much of them is used? Use this script first to find how buffer pools are set.
SELECT SUBSTR(NAME, 0, 22) NAME, SUBSTR(display_value, 0,10) VALUE
FROM v$parameter
WHERE NAME IN ('db_keep_cache_size', 'db_recycle_cache_size', 'db_cache_size');

NAME                   VALUE
---------------------- ----------
db_cache_size          30G
db_keep_cache_size     1G
db_recycle_cache_size  1G

The following script shows how much of each pool is used
SELECT DECODE(kcbwbpd.bp_name, 'DEFAULT', 'db_cache_size', 'RECYCLE',
'db_recycle_cache_size', 'KEEP', 'db_keep_cache_size')
buffer_pool_name, ROUND((COUNT(*)*:block_size)/(1024*1024),2) USED_MB
FROM x$kcbwds kcbwds, x$kcbwbpd kcbwbpd , x$bh bh
WHERE kcbwds.set_id >= kcbwbpd.bp_lo_sid
AND kcbwds.set_id <= kcbwbpd.bp_hi_sid
AND kcbwbpd.bp_size != 0
AND kcbwds.addr = bh.set_ds
AND bh.state !=0
GROUP BY kcbwbpd.bp_name;

BUFFER_POOL_NAME         USED_MB
--------------------- ----------
db_cache_size           30358.94
db_recycle_cache_size       2.66

Go to the Oracle GoldenGate Software directory.

[GoldenGate]$ $GG_HOME/logdump

Open a Trail File
To open a trail file and read it’s content, specify the trail file at the logdump prompt. Trail files are usually found in the GoldenGate dirdat directory.

ls -lrt $GG_HOME/dirata
-rw-rw-rw- 1 oracle oinstall 78325 Dec 7 10:38 GG000001
-rw-rw-rw- 1 oracle oinstall 78325 Dec 7 10:42 GG000002
-rw-rw-rw- 1 oracle oinstall 78325 Dec 7 10:55 GG000003
                                             
You can also determine the current trail file directory/name by running the “INFO process_name” command at the ggsci prompt.

Open and view the details of local trail file.

Logdump> OPEN ./dirdat/GG000001
Change the file name and location as required.

Set Output Format
Enable the following options so that you are able to view the results in a readable format in your Logdump sessionL

Set trail file header detail on
The FILEHEADER contains the header details of the currently opened trail file.

Logdump> FILEHEADER DETAIL

Record Header
Logdump> GHDR ON

Set Column Details on
It displays the list of columns, their ID, length, Hex values etc.

Logdump> DETAIL ON

User token details
User token is the user defined information stored in trail, associated with the table mapping statements. The CSN (SCN in Oracle Database) associated with the transaction is available in this section.

Logdump> USERTOKEN DETAIL

Set length of the record to be displayed
In this case it is 128 characters.

Logdump> RECLEN 128
Viewing the Records
To view particular records in the trail files, navigate as below in the local trail file.

First record in the trail file
Here “0” is the beginning of the trial file

Logdump> POS 0
