select username,account_status,default_tablespace from dba_users;
The ran the above query and it return 80 users but when i ran below query it shows just 14 rows.
select owner,sum(bytes)/(1024*1024) "GB" from dba_segments group by owner;how to get the size of all 80 users from database ?
get the actual password for the database users. If we talk about the dba_users account we have password in the encrypted form how to decrypt them and get actual password.

View 1 Replies View Relatedhow can we find the size of the oracle database 11g.
View 2 Replies View RelatedI have Oracle 11gR2 running on windows xp machine. Windows xp has total size of 150 GB and free space of 95 GB.
I checked the size of the database that I created. It showed the total size of the database as 2 GB and used space as 2 GB. If I want to increase the total size of the database to 50 GB, what should i do? Now which is the disk space size? Windows or Oracle?
I have checked the space of my tablespaces/datafiles in my database. I have 8 GB space left in my database server. I cant add more hard-disk as there is no slot left. We r planning to buy a new server with latest config.
My question is, how can we know upto what size our database can increase and when a datafile need to be added in advance. Sometimes even though datafiles have space left,it shows errors abt extents cannot be extended. We have coalesce the tablespaces and added a new datafile.
I am storing customer's snaps in a table ( column's data type as LONG RAW) using oracle forms Webutil. Now there are 250 snaps in the table. The file type of these snaps is JPG with the average size 30KB.
I made a backup using export utility before storing these snaps and the exported DMP file's size was 36MB. Now after storing these just 250 snaps of 30KB the DMP file's size is gone over 300MB.
i need to change column's datatype? or some where in oracle forms's image item. Because on window's file system the size of these files is just 8MB.
Our database size is 100GB and i removed few records from a table and rebuild the index.The size of Index reduced considerably after Index rebuild but now i see our database size increased to 115GB.I know online rebuild creates second index which is also removed after the build is finished then why the increase in database size?Is there a way so it shows up more space ?

a)Find out the list of objects added along with creation scripts
b)find out the list of objects modified along with creation scripts.

How to know DB size increase per hour or day on the Oracle?
View 3 Replies View RelatedI have one tablespace PSINDEX with Maxsize of 6 GB. But when I query the tablespace its showing the BYTES is greater than MAXBYTES.
View 5 Replies View RelatedI am working to understand the space allocation of table with the value we provided with the data type. For that I have created a table with varchar2 and length 50. Size of table created is of 65536 Bytes. This is when we don't have any insertion in the table. Later when we insert some rows, total size if the segment still remain same that is 65536 bytes.
Now again when I created table with varchar2 and length this time is 500 but still it is created with same size that is 65536. So can you just explain, on what values segment size depends on and how the length effect the size & space allocation.
db_block_size is 8192.

The problem is that the data of the table are 40GB while on the DB the table holds 400GB! How can I shrink and reuse that space except from drop/recreate and drop/import?
The table has no initial data, so that I can play with the INITIAL parameter. Data are inserted, updated and deleted all the time. I have run DBMS_ADVISOR which recommended to SHRINK table. I have performed the shrink :
alter table STG_XML shrink space COMPACT;
but I haven't gained any space.
As the undo segments are used in round robin fashion, Is it possible that with varying load (concurrent users, size and number of transactions), the size of Undo tablespace on a particular day is less than the Undo tablespace size few days back, by any chance?
As a basic understanding I know that Undo is preserved for read consistency and transaction, instance recovery So if there are lot of transaction on a database on 05 Feb and before that, but there aren't any transactions on 6,7,8,9, then on 10th Feb can we see the Undo tablespace size is less than that of 05 Feb?
In the following case when data belonging to table is not required for any queries, transactions, even then the undo size is not restored upon dropping the table.
As such for large operations and batch processes shall we keep undo tablespace with files as 'Autoextend' with 'Maxsize' as 'Unlimited'?
