Size of the database

HI All,
I have a 10GB database, when I backup the database using RMAN. What will be the size of the database approx.
Thanks

ThanksThe size of the database will be exactly what it was before the backup.
Oh, you meant what will be the size of the backup?
It depends.
Are you taking image copies or backup sets?
With or without compression?
A 10g database really isn't very big to start with. Why don't you just run a backup and see for yourself?
If you are trying to determine how much space you need to hold your backups, don't forget that it's more than "just a backup". You've got the db files, the control files, the archivelogs .... and multiple generations to allow PITR throughout your specified recovery window.

How to estimate the size of the database object, before creating it?

A typical question arise in mind.
As DBA's, we all known to determine the objects size from the database.
But before creating an object(s) in database or in a schema, we'll do an analysis on object(s) size in relation with data growth. i.e. the size we are estimating for the object(s) we are about to create.
for example,
Create table Test1 (Id Number, Name Varchar2(25), Gender Char(2), DOB Date, Salary Number(7));
A table is created.
Now what is the maximum size of a record for this table. i.e. maximum row length for one record. And How we are estimating this.
Please help me on this...

To estimate a table size before you create it you can do the following. For each variable character column try to figure out the average size of the data. Say on average the name will be 20 out of the allowed 25 characters. Add 7 for each date column. For numbers
p = number of digits in value
s = 0 for positive number and 1 for a negative number
round((( length((p) + s) / 2)) + 1
Now add one byte for the null indicator for each colmn plus 3 bytes for the row header. This is your row length.
Multiply by the expected number of rows to get a rough size which you need to adjust for the pctfree factor that will be used in each block and block overhead. With an 8K Oracle block size if you the default pctfree of 10 then you lose 892 bytes of storage. So 8192 - 819 - 108 estimated overhead = 7265 usable. Now divide 7265 by the average row length to get an estimate of the number of rows that will fit in this space and reduce the number of usable bytes by 2 bytes for each row. This is your new usable space.
So number of rows X estimate row length divided by usable block space in blocks. Convert to Megabytes or Gigabytes as desired.

How to find the total size of the database before the Restore.

Hi Guys,
I'll do a Restore, but I do not know the environment and need to know what the total size of the database to create a storage area.
Is there any way to find out the total size of the database(including all datafiles and temp) using only the RMAN catalog before running the Restore.
I'm using Tivoli TSM with ASM.
Levi Pereira

Hi tychos,
break on report
compute sum of TOTAL_DB on Report
select 'DataFiles' NAME, SUM(ROUND(bytes/1024/1024/1024)) TOTAL_DB from rc_datafile
where db_name = 'ORCL'
UNION ALL
select 'TempFiles' NAME, SUM(ROUND(bytes/1024/1024/1024)) TOTAL_DB from rc_tempfile
where db_name = 'ORCL'This query returned I had 372 Gbytes of data.
At the end of the Restore Database got the size of 408 Gbytes.
The total size of all Redo was 3Gbytes that was not being counted anyway there was a difference of 33Gbytes.
I need to understand the reason for the difference in sizes.
It makes no sense to me RMAN catalog does not inform the total size of the database (Datafiles, tempfiles, Redo and controlfile) before the Restore since it's information is already somewhere.
Thanks for your help.
Levi

How to know the Size of the Database?

Hi All,
Is there a Transaction which will give me the size of the Database. The Database System which we have is MS Sql Server 2000. Will the Transaction have the option where I could select the Client so that I could get the exact size of the Production Systems Database, will this also provide the size of the Data & Log file.
Thanks,

Calculating the size of the database in memory

Hi,
I am using BDB 5.1.19 with BTREE as an access method.
I would like to calculate the memory footprint that would be needed for that.
I followed the following doc:
useful-bytes-per-page = (page-size - page-overhead) * page-fill-factor
bytes-of-data = n-records *
(bytes-per-entry + page-overhead-for-two-entries)
n-pages-of-data = bytes-of-data / useful-bytes-per-page
total-bytes-on-disk = n-pages-of-data * page-size
I am not interested in calculating the size on disk but just in memory.
Would the following be enough:
bytes-of-data = n-records *(bytes-per-entry + page-overhead-for-two-entries)
Since the rest is only for space on disk i don't need it, is that correct?
Would this calculation help me also to calculate the cache size or is the cache size influenced by the page size?
Thx.

How to find out the database-size

Hello,
how can I find out the size of the database.
I created the user as below. I defined the size of the database to 2MB. Now I want to know how much is the size of the database.
CREATE USER oemer
IDENTIFIED BY ...
DEFAULT TABLESPACE system
QUOTA 2M ON system;

Actually, since Omer is a veteran poster to the Forms and Reports forums, I doubt that. I think he is making a much more interesting journey: from front-end to back-end.
I'll be a bit more helpful this morning.
Databases are ways of organising disk space to store data. Fundamentally they consist of OS files, data files. The RDBMS handles by grouping them into tablespaces. When we build tables we assign them to a tablespace.
So, the size of the database is the sum of its datafiles. Of course, some tablespaces are used for sorting and holding undo information, so the size of the database for the purposes of persisting data is:
SELECT count(x.tablespace_name) AS total_TS, sum(x.MB) AS total_mb, sum(x.free_mb) AS total_free_mb
FROM   ( SELECT t.tablespace_name, sum(d.bytes)/1048576 AS mb, sum(f.bytes)/1048576 AS free_mb
         FROM   dba_free_space f, dba_data_files d, dba_tablespaces t
         WHERE t.contents = 'PERMANENT'
         AND    d.tablespace_name = t.tablespace_name
         AND    d.file_id = f.file_id
         GROUP BY t.tablespace_name ) x
/The SYSTEM tablespace is special. It is used by Oracle to hold the data dictionary, the definitions of all the objects in the database. It should not be used for storing application objects (it affects the performance, apatrt from anything else). That is why we must not use it as a default tablespace.
CREATE USER oemer
IDENTIFIED BY ...
DEFAULT TABLESPACE ts_users
QUOTA 2M ON ts_users; Cheers, APC

How to find out the size of a database?

I'm not an oracle dba but a report developer. I'd like to find out the size of my database.
Is this possible using simple query?

An oracle database consists of data files, redo log files, control files, temporary files. Whenever you say the size of the database this actually means the summation of these files.
select a.data_size+b.temp_size+c.redo_size+d.controlfile_size "total_size in MB"
from
( select sum(bytes)/1024/1024 data_size from dba_data_files ) a,
( select nvl(sum(bytes),0)/1024/1024 temp_size from dba_temp_files ) b,
( select sum(bytes)/1024/1024 redo_size from sys.v_$log ) c,
( select sum(BLOCK_SIZE*FILE_SIZE_BLKS)/1024/1024 controlfile_size from v$controlfile) d;
here
a is megabytes allocated to ALL datafiles
b is megabytes allocated to ALL TEMP files
c is megabytes allocated to ALL redo-logs
d is megabytes allocated to ALL control files

How to find out the database size of a portal?

Hi all!
How can I determine the size of the database of one portal?
Thanks for your help!
PM

Hey Peter,
Just making sure off the top... you're using the same version of Oracle on both the source ABAP system with DBA Cockpit and the target Portal, correct?
Assuming you answered that in the affirmative, did you make an additional entry in the tnsnames.ora file on the ABAP system? This entry should reflect the target Portal database system to which your connecting. Make your change to the /oracle/<SID>/<DB_Ver>/network/admin/tnsnames.ora file. Once this is complete, copy that file to /sapmnt/<SID>/profile/oracle/tnsnames.ora.
Test your connection again after this.
Here's an excerpt from SAP Note 1261329:
Set up the database connection.
In the file tnsnames.ora that is in the directory (on the application server) to which the environment variable TNS_ADMIN refers, you must add the following entry for each Oracle remote database:
           <SID> =
             (DESCRIPTION =
               (SDU = 32768)
               (ADDRESS_LIST =
                 (ADDRESS =
                  (COMMUNITY = TCP)
                   (PROTOCOL = TCP)
                  (HOST = <database_host>)
                  (PORT = <port>)
               (CONNECT_DATA =
                 (SID = <DB_ID>)
This means that
<SID> = the ID that you want to use to access this database ("TNS Name")
<database_host> = host name of the database server
<port> = TCP port of the database listener
<DB_ID> = database ID of the database that is to be connected
Usually, you can copy the entry in the file tnsnames.ora from the relevant file of the remote system. To obtain the contents of tnsnames.ora in the remote system, log on to the remote system as the database user ora<sid> (UNIX or Linux) or as the database user <sid>adm (Windows) on operating system level. There, you call the following command from the command line.
tnsping <SID>
The output specifies the connection parameters and the path to the file sqlnet.ora. The directory in which this file is stored, also includes the file tnsnames.ora.
If you haven't seen them before, check out that note (1261329, 1028624, and 1256322). If you've still got questions, let me know.

Rman Backupset size is exceeding the database size

Hi
my rman backup size is exceeding the database backup size and occupying the full mountpoint. and finally due to space issue, backup is failing.
Below is the RMAN script
run {
backup
incremental level 0
tag ASCPLVL0
database plus archivelog ;
delete noprompt backupset completed before 'sysdate - 4/24' ;
Please look into this
Regards
M. Satyanvesh

Are you using compression?
Ans: No
The size of an RMAN backup isn't always proportional to the size of the database.
Ans: yeah I know, but it should be somewhere near to database size(lets say 100gb or 150 gb variance)
How many archivelogs are you backing up with your database? This is possibly a factor in the size of your db backup.
Ans: archive log count per day is 18 and size is 34gb
Have you got a retention policy in place and do you regularly delete obsolete backups/archivelogs?
Ans: yes
Are you taking this backup as part of a backup strategy? or is this just a one off for some other purpose which would seem to be the case.
Ans: This is production systesm so its a part of backup strategy

How to reduce the database size after deleting huge amount of rows?

Hi,
I have a large database. I removed almost half of the data/rows. Now i need to reduce the size of the database file as I need more disk space for the database file.
What should I do in details please.
Thanks.

Deleting large data would have ultimately put ghost cleanup into action. You would not be able to free space using shrink operation untill it completes. So wait for time and then start shrinking. You should note that shrinking would cause fragmentation and
you would have to rebuild indexes after shrinking is completed

How to estimate the database size?

Hello. I have a database model in SQL data modeler. Also I've created it on the test server, but it is empty now.
Now I need to estimate the size of the database for understanding the requirements to production hardware.
For, example how many gigabytes I need in two years for my database. How can I do it?
Thank you in advance.

It is called "volumetrics" in ErWIN.

Does Checkpoint lock up the database

Hi,
My application runs an independant checkpoint thread every 30 secs. The application is a msg processing system and it seems every 30 seconds, queues start building up. Does BDB lock the internal log files and database while checkpointing is going on?
Regards,
Nishith

Hi Nishith,
First of all, provide the following information:
- What is the BDB version you're using?
- What is the HP-UX version you're running on?
- Are the three databases associated, that is, is any of them a secondary database for one of the others? Are there subdatabases, that is, multiple database stored within a single physical file?
- What is the number of writer threads?
- I assume you've configured the DB_TXN_NOT_DURABLE flag for each database. Are you using implicit transactions (by configuring with the DB_AUTO_COMMIT flag) or explicit transactions (obtained through DB_ENV->txn_begin())? If explicit transactions are used, what is the number of writes enclosed within a transaction?
- Are you performing reads transactionally? Are you using transactional cursors to perform reads, and if so, what is the isolation degree used (i.e. DB_READ_COMMITTED, DB_READ_UNCOMMITTED)?
- What are the page sizes for the databases?
- What is the output of running the "glance" tool?
- What is the block size of the HFS/JFS file system (i.e. by default for UFS(HFS) it should be 64K)?
Try the following suggestions:
- Use the DB_ENV->get_mp_max_write() method to see the limitation on the number of sequential writes scheduled by the db library when flushing the cache's dirty pages. Try setting a lower limit (experiment with lower values each time).
- Experiment with a larger size for the cache buffer pool.
- Avoid creating databases with a considerable number of duplicate and overflow records.
- Perform all the read operations outside of transactions; if you do enclose reads within transactions than adopt snapshot isolation (available as of 4.5.20) or relax the isolation degree. Also, try to use the DB_READ_COMMITTED flag with cursor read operations and make non-transactional cursors short lived.
- Collect detailed statistics with the "db_stat" utility (if DB_PRIVATE is used when opening the environment collect the statistics programmatically):
#db_stat -Zm -h <path_to_env>
#db_stat -Zc -h <path_to_env>
(the commands should be run for 2 or 3 consecutive checkpoints).
Regards,
Andrei
