Moving From 1 Database To Another
Jul 25, 2013
I need to move everything from database 'X' to database 'Y' (assume: both are Oracle 11.2).Which should be the most appropriate way to achieve that?I thought of Transportable Tablespaces- URL..... but I'm worried about it's limitations especially this:SYSTEM Tablespace Objects - You cannot transport the SYSTEM tablespace or objects owned by the user SYS. Some examples of such objects are PL/SQL, Java classes, callouts, views, synonyms, users, privileges, dimensions, directories, and sequences This means all PL/SQL code- Packages/Procs/Functions will be affected.

But there is one schema EXMP in database ORCL which also exists in CNTR database with same tables, indexes . The data under schema EXMP in ORCL should be added to schema EXMP in CNTR.

We're currently in a situation where the primary database server fs size does not match the standby database server fs size.
Standby database filesystem is almost 100% utilized, and we suggested to move some of the datafiles first to avoid threshold alerts and archive gaps.
Now, if we're gonna move datafiles on the physical standby, I believe the process would be stop managed redo apply -> shutdown standby -> OS move -> startup mount -> alter rename -> start managed redo apply. Is this correct? If not, how?
Also, would it have an effect if the controlfiles of primary and standby do not match because of the movement?

We have an Oracle Server database of Size 50 GB having 10 GB Data. And Planning to have a new Database Server of 200GB . So my question is after moving all the 10 GB data to 200 GB Database Server, will the performance of the system come down? Will it reduce the speed?

I'm trying to run a report that has a moving date and I need to find data that's within 12 months of that certain date.
So for example... customers come in everyday all year long. I wanted to find the number of unique customers in a year. But the year is moving... So 1 year from 1/15/2011 is 1/14/2012. And 1 year from 1/16/2011 is 1/15/12. So I had something like this but doesn't quite work..
SELECT ...
NVL(COUNT(DISTINCT CASE WHEN TX.DATE_OF_FIRST_VISIT BETWEEN TO_DATE(TX.DATE_OF_FIRST_VISIT,'MM-YYYY') AND ADD_MONTHS(TO_DATE(TX.DATE_OF_FIRST_VISIT,'MM-YYYY'),12) THEN (TX.CLINIC_ID||TX.PATIENT_UNIQUE_ID)END),0) AS "YEAR_1"

I have imported data into database using sqlloader into flat table. Now I need to move the data from this table to another table. This is production system and I must keep it online. So I decided to make script that will move data in small chunks and commit frequently to avoid waits and table locks.
Regarding the script I have question. I can to the bulk load of rowids. Is it possible to optimize the insert and delete in similar way instead of doing insert/delete in loop for each rowid ?
declare
type t_rowids is table of rowid;
rowids t_rowids;
begin
loop
select rowid bulk collect into rowids from ims_old.values_f2 where rownum < 1000;

I am trying to create a trigger which does the following : A flag in the initial able is set to Y. When this happens, the record needs to be inserted into a history table and then DELETED from the calling table.
It must happen in triggers, but I keep getting the mutating error.I have tried to use a Compound trigger, but with no luck and just dont really understand how to get this to work.

I have a requirement to move the databases to a new server.
Existing set up:
database1-40GB,
database2-40GB,
database3-180GB
Oracle version - 11.2.0.2
OS - UNIX AIX-5.3
New Server (setup):
database1-40GB,
database2-40GB,
database3-180GB
Oracle version - 11.2.0.3
OS - UNIX AIX-6.1
My query is what is the best way to move the database to new server(UNIX AIX 6.1)?
a) can i upgrade the database to 11.2.0.3 before moving to new server or its better to move the database in 11.2.0.2 and then upgrade there?
b)is export and import of database can work for moving this?
c) RMAN backup and restoration can be done for moving databases?
d)simply moving all the related files to new server and start upgrading it from there?

We have a p/slq procedure that reads a *.txt file using the UTL_FILE package. The contents of the file are then inserted into a database table.
At the end of the procedure we close the open file using UTL_FILE.FCLOSE.
There is a program (non-oracle)that attempts to move the file to a new location after being read into Oracle. The problem is that the application cannot move the file as the file is locked. ie message displays that the file is open and cannot be moved to a new location.
Is there anything else that we are missing besides the UTL_FILE.FCLOSE.

I've inherited a DB where they are going to do a restore this weekend.
The current DB admin is using a db restore (not a duplicate). RMAN with no catalog. The current issue is that the DB restores fine, but when we do a delete obsolete after our backups it's asking if we want to delete the data files.

"All data you create in this tablespace will be encrypted using an AES256 encryption key. You cannot encrypt an existing tablespace. To encrypt data, first create an encrypted tablespace, then use alter table move, CTAS or datapump import to move your data into the encrypted space. Remember to drop the old tablespace BUT not including datafiles. Use an OS schred program to remove the old datafile. If you are on ASM you may use the including datafiles option since you can’t schred files from the OS inside an ASM instance."
But i want to know why we should NOT drop the including datafiles, when dropping tablespace (so 'drop tablespace my_tbs including contents and datafiles'). So what option should we use when dropping tablespace?
Why we should use OS capabilities to remove the datafiles?
What happens if i remove the datafile when i drop the tablespace?
