We have Employee table, there is a field name Employee_no. field size is 6.can we restrict some one not to increase or decrease the field size of Employee_no. even User has admin role.
is there any way to restrict admin user that he should not allow to enter the value of field more or less than 6 characters through Toad or SQL Plus 8.0.
------------------------------------------------------
for example
When we enter Employee no A000001(7 digit) then database not allowed to update because its field size is 6 characters we want to restrict admin user in Toad or SQL Plus 8.0 because he is Toad and SQL Plus user.
I will be installing SOA Suite with OSB in Exalogic for testing. It is not for the production environment and very simple application will be used for testing. Database admin asked me what size database would be required but I did not find clear answer in the documentation anywhere.
We have Oracle 10G database over Unix platform, Customer want to reduce the size of database as much as possible and the ami of customer to move the storage area of this database to other one. so we resize some datafiles and get lots of free space at mount point but while checking the utilzation of table is showing some what different as other. Below O/P:
% % MaxPoss Max Tablespace Name KBytes Used Free Used Largest Kbytes Used ------------------------------ --------------- --------------- --------------- ------ --------------- --------------- ------ *a DATA 45,875,200 8,740,992 37,134,208 19.1 1,728,512 100,663,248 45.6 *a HIGH_S_DATA 21,504,000 1,331,520 20,172,480 6.2 3,048,704 0 .0 *a HIGH_S_IND 15,360,000 853,568 14,506,432 5.6 1,661,504 0 .0

above all o/p is different, no able to understand it. is there any way to reset the HWM at Datafile level and how we reset the HWM of those tables having Materlized view?
If I have NO datafiles other than of the default block size, would I need to define a size for those other buffer pool? Is there any process that would benifit of these pools?
I 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.
i have created a database on my pc and i have given a password at the time of installation , after the installation it is accessed successfully by the given password , but i observed that when i gave anything in password then it is also accessed by it and i don't have any other database of this same name.
And when i access it through another system then it is accessed only by its original password not by any other password.
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 ?
select sum(bytes) from dba_segments where owner='abc' and segment_name='abc_index_1'; 8GB
ALTER INDEX abc_index_1 REBUILD ONLINE ;
select sum(bytes) from dba_segments where owner='abc' and segment_name='abc_index_1'; 2GB
All the analysis till now on our system proves that our system is clearly I/O bound and db sequential read is the biggest culprit.
We have even identified the index which is being affected by sequential read. I am thinking of creating a new tablespace with 32K blocksize (currently all table spaces are 8k) and migrate this index to the new space. That way, Oracle will have to do less number of reads to get the required data.
But is there anything wrong in having just one tablespace with a differnt block size? Or is there anything that I have to be watchful about while doing it?
Is there any setting on oracle that allows to disconnect users automatically and display a message to users such: "Try a new connection to the db in 30 minutes"?
We currently hardcode the password inside our Java application to make the connection with the Database,this makes the password to be visible to all users who can read the application code. How can we encrypt the database password so we don't have to hardcode it into the application?
what sort of queries IT auditors run against the database? assist me wit these so that I can run them before hand in order to sort out any security vulnerabilities which we might potentially have prior to this being picked up by external auditors?
I am having one table Where,different country names are stored. while viewing data, I have to make sure that if country name having "USA" can only view its data. How can i do at DB level without passing where clause. Is Virtual Database in this case?
How can I export FGA / row level security policies from one database to another? I have created a new version of my schools ERP database, with upgraded application software, and now need to get the policies from our current production system to the new one.
I'm checking the possibility to use Active Directory to log on the our Oracle databases. But only for dba's and developers, not application users. We use Oracle 10.2.0.4 (and soon 11g) As OS on the databaseserver we use AIX5L 5.3
Is it possible to implement Active Directory on databases running on AIX ? If it is possible, what must be done to get it to work, software ... etc ?
