Getting the tables actively used in the schema
Hello,
We are in need of releasing space from the schema we use.
Can anyone please suggest how to find the tables that has not been used for a given amount of time. So that we can drop the tables which are not effectively used by the application..
Thanks and Regards.

Thanks for the replies ..
Actually the application was designed/created long back .. Lots of changes has been incorporated and lots of features has been removed from the application..
But in the backend the associated tables were not removed and we feel that it occupies huge space in the server ..
I am afraid i can enable auditing as it is a production instance and lots of formalities are involved if we have restart the server ..
Is there any other way to find out the tables which has not been touched, for a period of time ..
The project has been switched over to many people so there are no proper documentation available .. So we are forced to find some alternatives to identify the unused tables ..
Thanks,
Sathiya.What about using triggers and logging?

Change the Table being used insight the Procedure
Dear All,
I had 1 table "Customer" which is being used in 100 store procedures.
Now I rename that table to "Customer_Q".
Is there any method in SQL to repoint that table name insight All procs, without open my procedures?
If not, pls suggest any smart way..Can you please throw some more light into it !!
Another way is this which will do replace behind the scene
DECLARE @Script varchar(max) = ''
SELECT @script = @script + REPLACE(definition,'CREATE PROC','ALTER PROC') + CHAR(13) + CHAR(10) + ' GO ' + CHAR(13) + CHAR(10)
FROM sys.sql_modules m
INNER JOIN sys.objects o
ON o.object_id = m.object_id
AND o.type = 'P'
WHERE definition like '% TableName %'
--double check script before execution
SELECT @script
--once happy uncomment below line and run full script again
--EXEC (@Script)

Get the Table name by providing the Sequence name
Hello,
I wish to retrieve the table name to which the sequence is related.
I understand that when the sequence was created, no reference is mentioned to any table. The sequence may be used across many tables.
But the DB definitely knows internally how many tables are referencing the particular sequence.
So, can anyone help me in finding the table (or all tables) referencing one particular sequence.
Thanks and Regards
(Please treat this as urgent as i am desperately in need of such a query)I share Adrian's scepticism. Using the data dictionary we could find all the program units - TRIGGERS, TYPES, PROCEDURES, etc - which use the sequence. From there we can find all the TABLES that are also referenced by those programs. And that's as good as it gets in Oracle. We cannot definitely say which tables use which sequences (although a good naming convention helps).
Of course, your DBA may have access to some accurate and up-to-date documentation. But that is maintained externally to the database and not derived from it.

When I attempt to log on to I tunes I get the following message:
"The registry settings used by the I Tunes drivers for importing and burning CDs and DVDs are missing.
This can happen as a result of installing other CD burning software. Please re-install I Tunes."
To my knowledge no new software has been installed. I have tried un-installing and re-installing I Tunes but I still
get the same message.
Can anyone offer any suggestions? Do I need to download a new driver?
Bill MartinI can get down as far as step 11 but it shows nothing about upper filters and when I type on "If the Upper Filters entry is missing follow these instructions" nothing happens
Do you mean you can't see the instructions on what to do if there is no UpperFilters entry?
If so, here's the relevant instructions for that step:
On the right side of the Registry Editor window, right-click the UpperFilters entry and choose Modify from the shortcut menu.
Right-click the empty white space within the right-hand portion of the Registry Editor window. From the shortcut menu, choose New > Multi-String Value.
Name this new value "UpperFilters" (without the quotes). Then, right-click the newly created UpperFilters entry and choose Modify from the shortcut menu. -
when i start up i tunes i get the message,"The registry settings used by the i Tunes drivers for importing and burning CD's and DVD's are missing. This can happen as a result of installing other CD burning software. Please reinstall i Tunes." I tried reinstalling and still get the same message. when I ran the i Tunes diagnostics is says that the high and low filters are missing.
when i was having trouble with my optical drive(before Dell sent me a new one) the dell tech support representative had me delete some reg. files to try to fix the problem. I was told this would not affect the new drive when i install it or any of my existing programs. here is what he had me do....

how can i get this message box to stop poping up every time i open i tunes? otherwise i tunes works fine. it still rips cd's. I just keep getting this message even after reinstalling i tines.

How do you get a table to flow onto the second page?
Since upgrading to Yosemite, I cannot figure out how to get my table to continue on to the second page. If you look at my screenshot, you can see that my table was so big so the whole thing was moved to the next page. I want it to remain on the 1st page and have additional rows continue on to the second page. In the previous version of pages, the column titles would also appear on the second page. Thank you very much for your help.
Hi F.AD.;
Go to View > Show Invisibles (Shift+Command+I).
This will display Paragraph marks (¶) at the end of each paragraph.
Delete the paragraph mark (¶) that is at the end of the paragraph before the table, i.e. just between the table and the paragraph.
This will bring the table surely just beneath the paragraph (text), I suppose.
Hi BePositive26;
You didn't mention whether my suggestion made easy to solve your problem.

When starting iTunes I continually get an error message " The registry Settings used by the iTunes drivers for importing and burning CDs and DVDs are missing.

I have unistalled and reinstalled iTunes several times and have cleaned up the registry using a 3rd party Windows utility. Any tips on removing this error message for good?
I'd start with the following document, with one modification. At step 12 after typing GEARAspiWDM press the Enter/Return key once prior to clicking OK. (Pressing Return adds a carriage return in the field and is important.)

Get the table's rowid of the session that is locking in RAC database
I am a developer and not a DBA and I need to find th correct query to find the exact rowid of the record locked on a table. This is for a RAC database and locked record can be from the web form in oracle application server. When I try to get the correct row id, I get the following error:

Identifying locked rows
And the last bit from Randolf
>
It is a common misconception that you can locate a locked row in Oracle via a query. The point is that the information that you're querying only gets populated in case of a blocking lock, and even then not in every case, since you might have blocking locks that do not refer to a particular row.
Oracle stores the lock information within the block, so if you identified in which block the row is located that you've attempted to lock, you could get detailed information about the row locks of that block by performing a block dump.
Other than that Oracle doesn't maintain this information anywhere else and it is only externalized for blocking situations - it is a matter of design that there is no central lock manager in Oracle that would inherently limit scalability, hence the downside of that approach is that there is no central information pool where you could obtain detailed information about row level locks.
>
However, if you see support note "Sample Code to Select from a Table EXCLUDING Locked Rows [ID 186531.1]"
You can take the same code from the script in that note to identify rowid of the locked rows. -
