Import - Moving Data From 10g Enterprise Edition To 11g?
Sep 23, 2013
Am moving data from 10g enterprise edition to 11g standard edition using normal import commandafter completing i just go through the Log.i found a thing which makes me confusing
in some tables alone a row is not inserted stating the ORA-12899 while checking with the database it shows the column is varchar(100)in the log the error showing it tries to insert 101 character. how it happening to a single row
The only supported technique for converting an EE database to SE is export-inport, as documented in note 139642.1. Our client is reluctant to do this because of the downtime involved. It is however possible to open the EE database from an SE home, no problem.
The note says only Quote:When you just install the Standard Edition software, you will end up with Data Dictionary objects which are of no use (or perhaps even invalid) and possibly create problems when maintaining the database.
My problem is i install Oracle 9i enterprise edition 9.0.1.1.1 in windows xp professional but at the time of oracle database confiuration assistent it show me following errors it show:
when migrating from 32 bit Linux to 64 bit Windows version on database standard edition, is there a server media needed?if yes, can you give me more details on what it consists of?
I have an 11g data pump supplied by another party.I am on Windows 7(x64).I have experience using other databases, but not Oracle. The complexity of it all is a bit overwhelming...
I downloaded and installed [URL].I used the Database Configuration Assistant to create a database:
Template: Data Warehouse Name/SID: database0 Password: password0
I then used the 'database0' Enterprise Manager:
Logged in as SYSTEM/password0 (Normal) Import from Export Files Entire Files Host Credentials: myself (am Windows administrator) All the rest defaults
The job appears to finish successfully.When I look at the schema (using razorsql), most tables seem to be there. However,a significant number are not. When I open data pump in a text editor, those missing tables are clearly there - definitions and data.When I look in the import.log, there are errors of the type:
error in creating database file '/db02/oradata/database0/stuff.dbf' file create error, unable to create file unable to open file (OS 3) The system cannot find the path specified. Failing sql is: CREATE TABLESPACE "STUFF" DATAFILE '/db01/oradata/database0/stuff.dbf'
-- followed by the associated table creation errors.
So, does this mean that unix paths are hardcoded into the data pump, and is therefore incompatible with import into a Windows based system? Or are the paths symbolic, internal representations used by Oracle, and these errors are a symptom of an earlier, undisclosed problem?
The thing is, when I view the schema, the tablespace "STUFF" exists, just none of its tables.
Recently we have downgraded our database from enterprise to standard edition.....our sga size before downgrade was 11 gb and now it is 11gb and there is no as such problem in database..I have read somewhere that standard edition doesn't support sga size more than 2 gb .
I am checking out licenses. We all know that EE is much more expensive than SE. But many customers do have EE installed - unsure if they need all the features at all. After several years of production, a downgrade is considered 'risky' and we continue to pay the full EE.
How can we check and be sure that a downgrade to SE would not be any problem?
Some checks include: * partitioning used in user schemas? --> no downgrade to EE * bitmap indexes in user schemas? --> no downgrade to EE
How can we complete this list, or is there some script to make this easy?
Ours is Oracle 11.2.0.2.0 Db 4 instances RAC on Unix AIX OS.Since long we are facing problem that CPU utilization reached 100% and reboot is required alteast once or twice a month.On seeing the Events Logs we find that the Event "CURSOR PIN S WAIT FOR X" is consuming a lot of waits.
On analyzing i came to know that we are firing same query from Application 15 to 20 lack times for which a lot of Mutex keeps spining for getting Shared Mode and consumes a large amount of CPU.
I am querying v$sga and getting variable size : 211337216 bytes.when querying v$sgastat then getting
java Pool : 16777216 Large Pool : 41943040 Shared pool : 398560392
But as per my knowledge following condition should satisfy,but not getting
[code]
Variable sga = java pool + large pool + shared pool select pool,name,sum(bytes) from v$sgastat where pool in ('shared pool','java pool','large pool') group by pool,name;
Here variable size using v$sga : 211337216 bytes
and java pool + large pool + shared pool : 211302536 bytes.
In our current setup we have RAC on standard edition and client is now planning to go for Enterprise Edition but not yet decide because of cost. Is there any difference between Grid Infrastructure 11gR3 Enterprise edition and Standard Edition ?
They told me to first install Enterprise Edition and then will move to Standard Edition if they can't get the EE license so in that case do i have to re-install Grid infrastructure for standard edition?
In my Production DB. 5 Datafiles created in same tablespace. Datafile size is of 25GB. Data stored in all Datafile. Data is just 5GB in all datafile. I want to move data from 5 datafiles to single or couple of datafiles.
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;
"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?
My form has two list boxes and two buttons add and remove. As and when i click add button, the selected value from left hand side list item should get populated to right hand side list item. And When I click Remove button, it should do vice versa.
I try to transfer data from one database to another one through data pump via SQL Developer (data amount is quite important) exporting several tables. Tables export is doing fine, but I encounter the following error when I import the file (I try data only and data + DDL).
"Exception: ORA-39001: argument value invalid dbms_datapump.get_status(64...= ORA-39001: argument value invalid ORA-39000: .... ORA-31619: ...
The file is in the right place, data pump folder of the new database. User is the same on both base, database version are similar.
When I do the import the of succeeding dump, I drop the existing schema "SQL> drop user username cascade;" and import dump by " impdp system .... ". I would like to import a dump to an existing instance but only data import and will leave the current packages and other metadata untouched and unchanged on the said existing instance.
1. Do i need to drop user before the import if my requirements are the above?
2. If i need to drop user, what should be script.
3. For the import itself, what parameter should i use?
4. What are the necessaries I need to consider before doing the import.
my customer wants to create a standby database for his production database (Oracle Standard Edition 11g R2 @ Windows 2008 R2 64 Bit). Now any proof-of-concept which explains shortly the concept and how to achieve it.
Export and import of data in oracle forms...i have created 02 boutons one for export his trigger like this:
eclare alrt number; v_directory varchar2(200) := 'c:ackup'; --- that if the C Drive not the Drive that the windows had installed in it. path varchar2(100):='back_up' ||to_char(sysdate,'dd_mm_yyyy-hh24_mi_ss'); v_exp varchar2(200) := 'exp hamada/hamada2013@orcl file = ' ||v_directory ||'' ||path ||'.dmp'; [code]....
this code is correct he expot not only the data but also the creation of the table ....for exemple i do export and everything is good until now and i find the .dmp in the folder backup .. but when i deleted all data from my app and try to import this .dmp iit show me error it tell me thet the table phone is already created...just export the data of phone not the creation of table and data ???? or how can i import just the data from this .dmp ??
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 need to import some data from .csv files. There is one file each day, so I want them to be automatically imported into the DB. This is the format it comes in:
so filename is the actual name of the .csv file that this row came from. And reading id is date, num1, num2, meterid combined. And the remaining fields coming from temp_table
I need to move data from non-partinioned table to partitioned. The volume is about 60 millions rows. What is the fastest way to do that? I think about pareller insert and nologging. What do you think about this? May data pump be faster?
I have a table called Daily_usage (only 1 day data) which contains daily transaction records. After a day I have to move this data to another table named Daily_30days_usage table. this table contained the 30 days data. After 30 days the 31st day data should be deleted from Daily_30days_usage table.
How can I implement this requirement without INSERT statement?
