SQL & PL/SQL :: Importing To New Character Set And Its Affect On Encrypted Data
Nov 9, 2010
We are exporting from a 9i db to an 11g. During the migration, we are changing our character set from USASCII7 to AL32UTF8 so that the "extended" characters that our users like to put in text fields are stored and retrieved properly.
However, we've found a problem, and i'm not sure if Oracle has a method of dealing with. Searching this site and Oracle docs got me nowhere.
We store account #'s and credit card info in the DB encrypted with the dbms_obsfucation_tookit. We have an encryption key cross reference table that we use to store the key to un encrypt the data.
However, what we've found is that by importing these keys into our new character set database, the keys are no longer valid and can't be used with the DES3DECRYPT function to get the correct numbers out.
Is there a conversion utility or any tool that Oracle provides to maintain the encrypted datas "decrypt ability"? Worse comes to worse, we will have to write a script/procedure to decrypt everything on the 9i, import it to 11g, and then re-encrypt it.

I have oracle 10.2.0.4.0 installed on Window server 2008 [Machine A] and oracle 10.2.0.1.0 on windowx xp [Machine b]. Now I have taken the export of database on windows server 2k8 [Machine a] by puting the entry in the tnsname.ora file of Windox XP [Machine b].
Now when I am importing on the same machine I am getting the below mentioned error:

"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?

We have a primary and a standby (Physical Dataguard) site.
1. How do i check if the database is encrypted or not on primary as well as standby ?
2. If primary and standby are encrypted, does the data that gets replicated from primary to standby also in encrypted form ? If not, does it make sense to encrypt that ?

I am considering all of the capabilities and benefits of using Data Pump for exporting and importing extremely large data files. Would like to know if importing to tape is possible? If so, would the data be accessible if needed later?

I'm trying to figure out how to import data from another schema for an oracle SQL project in an MIS Course.Each student/schema created the following tables STUDENT, FACULTY, COURSE, IS_QUALIFIED, SECTION, IS_REGISTERED. Each student was supposed to make up names and ID numbers for 20 different students, then use real university faculty, courses, and sections to populate the respective tables.
I need to import data from all of another student's tables, without duplicating any courses, faculty, etc I already have in my tables.
The other student already granted acess to her tables, so now I'm just having trouble with the insert statement. This is what I have so far for the first table.
INSERT INTO myschema.STUDENT
SELECT * FROM otherschema.STUDENT
I know i need to add a "WHERE" statement to successfully copy the other persons data into mine, without duplicating any results. This is the last part of this project and I'm having trouble finding the answer anywhere.

Actually, i found that some forms if they are changed (like some buttons/text fields/code added to them) and this change can be saved and there is no errors in compilation. but when this form is run from the application, the change is not visible.
Even if the form with the image is removed from the directory, it still runs from the application link. Is there some memory issue or anything else.

I have received a dump, which i need to put on a newly created schema, there is a particular table with more then 4 million rows, and other tables have hardly few thousand rows.
I want to import it in a way where only 1000 rows get imported for this table and other tables do not get affected. Is there a way to do it?
Note: Tables in dump are more then 200.

I have a query regarding importing data in a partitioned table. let me make myself more clear with an example:
I have 1 month table that contains 30 partitions single partition for a single day on one machine say machine A. on another machine say machine B i create the same table with the same script which is on machine A for the same table. i loaded data till 1-15th of a month in Machine A table and rest of 15 -30 Days data into table on machine B at the end i want to import the data on partitioned table on machine B that is from 15th -30th to machine A table. I just want to know whether data is properly imported or not not or i need to specify something
I take export partition wise (15 -30th) 15 partitions dumps and imported into Machine A table. Is it possible that i can import day wise partition from 15th to 30th into a partitioned table which already contains data from 1st -15th partition.
I know this is possible

how do we know database character set is either single character set or multi character set?
While changing character-set from AL32UTF8 to WE8MSWIN1252 got "ORA-12712: new character set must be a superset of old character set".
Below are steps taken to resolve the issue -
ALTER DATABASE CHARACTER SET WE8MSWIN1252;
i got this error: ORA-12712: new character set must be a superset of old character set
below are the commands executed by me:
SQL> SHUTDOWN IMMEDIATE;
SQL> CONNECT SYS/password AS SYSDBA;
SQL> STARTUP MOUNT;
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL> ALTER DATABASE OPEN;
SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE WE8MSWIN1252;
SQL> SHUTDOWN;
SQL> STARTUP;
SQL> QUIT;
And its working...
I have not done it in proper order. Neither have done ccsscan. Still, no user reported any issues. Do my changes truncated the data?

I had a few regions on my page, the 2nd did not start a new row so it appeared horizontally where possible.During some experimentation, I created a new region with a sequence in between that started new row, but even when that region was conditionally never, my original 2nd region started on new row.
Original:
Region 1 - Region 2(empty) - Region 3 (new row/col no)>
New region added:
Region 1Region 1.5 (added, new row)
Region 2
Region 3>
Region 1.5 not shown:
Region 1Region 2
Region 3>
Let me know if you would like a test case for better visualisation.

OS: RHEL
DB: 11.2.0.2
Every time i try to refresh my production DB with the a old expdp dumpfile using data pump i always face the issue of grants and creation of synonym. I would like to tell you that my DB has three schemas which have lots of dependencies among them and before refreshing them i drop the schemas and recreate the same.
Drop user user_name cascade;So i want to know, is there a script from which i can get all the grants of the DB before dropping the schemas, so that after import i can grant the same and also a query with which i will be able to get all the synonyms of the DB.

I'm importing data from SQL Server to Oracle. I used BCP to export the data from SQL Server. Below is the 1st record of table trlc from the csv file.
trlc.CSV
11032|100|Wman| | |2008-02-08| |
Using SQL Loader to import into Oracle:
TRLC table in Oracle database:
est_no varchar2(10) default ' '
right_no number(4) default 0
maj_auth varchar2(15) default ' '
weight varchar2(10) default ' '
idm_ht varchar2(8) default ' '
c_date date
P_tkt varchar2(5) default ' '
sqlldr user/pwd@db02 control=trlc.ctl log=trlc.log
trlc.ctL:
load data
infile 'trlc.csv'
replace
into table trlc
fields TERMINATED BY '|'
TRAILING NULLCOLS
(est_no,right_no,maj_auth,weight,idm_ht,c_date,P_tkt)
The rows get inserted successfully. But the result sets are different, for example: When I do a select in SQL Server,'select len(weight) from trlc;' , I get the length as 0. But when I do a select in oracle database, I get the length as 1. Also, the result set varies for the query below:
select * from trlc where weight=' ';
(SQL Server returns 1 row but Oracle returns no rows)
Do I need to mention any conversion code for the weight field to accept ' ' value?

I created an encrypted tablespace for testing. I later dropped it but don't remember if I specified "including contents and datafiles". The tablespace was empty and there are no datafiles for it. However, the information for this dropped tablespace still shows up in v$encrypted_tablespaces. How do I get that lingering information removed?

We have over 200 different servers that are running Oracle and every 2 months, we have our passwords expire. Instead of having the DBA's go into every server to sync the passwords I would like to have some sort of way of pushing the encrypted password in the Oracle DB to other databases.
Two things to keep in mind.
1) Every user may not be in every DB so if the user does not exist, the code should not try to update that users password
2) I have all my DB's in a tnsnames.ora file or I can put into an easy to parse file, so I can connect to every DB.

eg. I am using a delimiter 237(í) and if the same character is present in data it should be escaped by escape character eg. /.
Once this file will get created i need to load this file in Netezza database which supports escape character.

note we need to decrypt the data which is encrypted using dbms_crypto.hash algorithm. it is possible to decrypt dbms_crypt.hash
eg
SQL> select DBMS_CRYPTO.hash(utl_raw.cast_to_raw('Foo'), 3) FROM dual;
DBMS_CRYPTO.HASH(UTL_RAW.CAST_TO_RAW('FOO'),3)

I have created and formatted a mini test scenario. Execute the scripts I have below?
From the column adj_second_line, I am trying to clip everything from the characters '201' all the way to the end...or the NUMERIC start value after the word 'TYPE'. Whichever way is easier for you...

insert into test_split
values ('ADJ#13 43327DR TYPE AJ 20100413 20100524 0MO/30HT')

SELECT adj_second_line,
