size of the database

Similar Questions

• Calculation of the size of the database.

  Salvation of DBA. Which is exactly the way to calculate the size of the database? Is it calculate the sum of the sizes of the segments or the calculation of the sum of the sizes of the redo logs, data files, control files?

  You please suggest the correct answer

  Thank you

  As usual: depends: do you need to calculate the size allocated on storage, you simply go to the current size of the file dba_data_files bytes column data. If you need the storage used the sum of dba_segments fits better. If you need the size of all files used for the database, you must add the controlfiles, newspapers and db_recovery_file_dest_size files.

• Query for the size of the database

  I need a query that should display the database size and the size of the database a month back. I tried with the OEM, but if the database goes down between the two, it will not display the result. (OS-HP-Unix, Linux, worm - 8i, 9i, 10g)

  Check this query:

  SELECT ADD_MONTHS (SYSDATE, -1),SUM (BYTES) / 1073741824
    FROM v$datafile
   WHERE creation_time < ADD_MONTHS (SYSDATE, -1)
  UNION ALL
  SELECT sysdate, SUM (BYTES) / 1073741824
    FROM v$datafile;

• Size of the database necessary for the composer

  Hey all,.

  I have composer view installation in my lab at home to learn and test its functionality, use SQL Express. Now, I want to test with my business deployment. I need to contact my DBA for the SQL database has been created. I'm not really familiar with databases at all. My manager suggested I join him and our dba ask tell them what size of database we need and create the database. Since then, I don't know much about databases, I have no idea what database size I should be in him asking to create. In addition, should I get this database created on our production or test sql server? I guess production since my end-users will use this and once set up it would be problems move the DB later? Yet once again, I have no idea... so I ask the experts

  Thanks in advance

• With regard to the size of the database

  Hi all
  
  Sorry for the interruption of you and your time for the clarification.
  
  The size of my database is:
  Select sum (bytes) / 1024/1024 of dba_data_files;
  
  SUM (BYTES) / 1024/1024
  --------------------
  19035.0938
  
  The size used is:
  Select sum (bytes) / 1024/1024 in dba_segments;
  
  SUM (BYTES) / 1024/1024
  --------------------
  5488.22656
  Free size is:
  Select sum (bytes) / 1024/1024 dba_free_space;
  SUM (BYTES) / 1024/1024
  --------------------
  13890.1016
  
  When I take plenty of RMAN backup I found the size almost 2304 MB (but in dba_segments his ~ 5488), my doubt is how to remove the higherwatermark (HWM) so that I can get exactly space used by database (excluding higher watermark).
  
  Thank you in advance,

• How to reduce the size of the database

  Hello
  My database size is 100 GB and used space is that 24GO means 76 GB of free space. I want to eliminate this free space. What should be the best solution for it?
  
  Thank you

  Hello..

  Can you name the database version?

  You can create new spaces for storage of the required size (little more size in use) and move all objects (TABLES) to new bases and then rebuild the index corresponding to these tables.

  I had read that, SYS_EXPORT_SCHEMA_XX are created while taking the dump with expdp and if stop you it without a showdown at work, this kind of remains of tables in the DB.
  
  I CAN DELETE THESE TABLES, BECAUSE IT IS TOO MUCH SPACE. ???

  Oracle will create master tables in the format you mentioned taking the export using expdp
  You can drop them and nothing will happen even if the database is running.

• The total size of the backup database and Total database size.

  Hi Experts,
  
  How can I find the size of the size of the database and the size of the backup with only the RMAN catalog help.
  I use Oracle 10.2.0.5. and Tivoli TSM
  
  I have

  Hello

  See this doc...
  http://download.Oracle.com/docs/CD/B28359_01/backup.111/b28270/rcmreprt.htm#CHDBIGHG

  Connect to SQL * for the database you intend to question the backup history.

  Ask the view V$ RMAN_BACKUP_JOB_DETAILS for more information on the backup type, status, and the start and end time.

  The following query shows the history of the backup jobs sorted by the session key, which is the primary key for the RMAN session:

  COL STATUS FORMAT a9
  COL hrs    FORMAT 999.99
  SELECT SESSION_KEY, INPUT_TYPE, STATUS,
         TO_CHAR(START_TIME,'mm/dd/yy hh24:mi') start_time,
         TO_CHAR(END_TIME,'mm/dd/yy hh24:mi')   end_time,
         ELAPSED_SECONDS/3600                   hrs
  FROM V$RMAN_BACKUP_JOB_DETAILS
  ORDER BY SESSION_KEY;
  

  Ask the view RMAN_BACKUP_JOB_DETAILS V$ at the rate of tasks of backup in an RMAN session.

  The following query shows the speed of backup job sorted by the session key, the primary key of the RMAN session. The in_sec and out_sec columns columns display the input data and output per second.

  COL in_sec FORMAT a10
  COL out_sec FORMAT a10
  COL TIME_TAKEN_DISPLAY FORMAT a10
  SELECT SESSION_KEY,
         OPTIMIZED,
         COMPRESSION_RATIO,
         INPUT_BYTES_PER_SEC_DISPLAY in_sec,
         OUTPUT_BYTES_PER_SEC_DISPLAY out_sec,
         TIME_TAKEN_DISPLAY
  FROM   V$RMAN_BACKUP_JOB_DETAILS
  ORDER BY SESSION_KEY;
  

  Ask the view RMAN_BACKUP_JOB_DETAILS V$ for the size of the backups in an RMAN session.

  If you run the DATABASE BACKUP, then V$ RMAN_BACKUP_JOB_DETAILS. OUTPUT_BYTES indicates the total size of backup games written by the backup task for the database that you are backing up. To view the backup set sizes for all registered databases, ask RC_RMAN_BACKUP_JOB_DETAILS.

  The following query shows the speed of backup job sorted by the session key, the primary key of the RMAN session. The in_sec and out_sec columns columns display the input data and output per second.

  COL in_size  FORMAT a10
  COL out_size FORMAT a10
  SELECT SESSION_KEY,
         INPUT_TYPE,
         COMPRESSION_RATIO,
         INPUT_BYTES_DISPLAY in_size,
         OUTPUT_BYTES_DISPLAY out_size
  FROM   V$RMAN_BACKUP_JOB_DETAILS
  ORDER BY SESSION_KEY;
  

  The following sample output shows the speed of the backup jobs:

  Hello..

  To know the size of the scheme: -.

  select owner,sum(bytes/1024/1024)MB from dba_segments group by owner;
  

  TO know the actual size of the database

  select sum(bytes/1024/1024/1024) Actual_size_gb from dba_segments
