Hi ,

I am working in Oracle 10g. I am new to DBA.
Requirment: I have a database in onsite ( some other place). i am connecting to that DB. Here the data retrieval is very very slow. so i want to replicate the same DB to my local. The db size is big.so i can not ask them to export the db and sent it to me. i want to replicate the same db here locally.
If also i dont have a system/sys password then also how can i perform this task.

thanks
deepak

Ask your dba which know sys/system password.

Shut down the database and copy all the files (data files, password files,control files, spfiles ) to new location.

Take a backup of the source database and restore it in the new location( like perform diaster recovery).

You can use RMAN duplicate Database.

If you don't have DBA privileges to set up replication then you simply can't.
If your performances problem comes from network and want a replication of live database then you can't.
If you want to replicate from time to time, then the best way is to use your source database backups and restore them locally or use transportable tablespaces if it is possible (see restrictions on documentation).

Regards
Michel

I am suspicious about his requirement. As he once said network is so so slow and again he said replicate , so I considered myself that he wanted to mean how he can get duplicate of database.

I agree with you Arju.
It seems to me OP only wants to faster query the same database/data.
So duplication seems a better way than replication.
Of course, it depends on the ratio "needed data"/"whole database".

Yes, I think i made my requirment complicated. Actually i want a duplicate schema rather than the whole databse.
Actually the server is in a different country itself. so i cant take a backup of the database locally ( also i dont have a system password). What i want is , to which schema i am connecting thru client , i want that schema in my local server.

thanks

I can suggest you to use network mode data pump import which seems to me best feet to your requirement.

You can also use transport tablespaces feature if your specified schema holds self contained tablespaces.

Once again, investigate if network is not your problem, if you want a up to date database or only one refreshed from time to time and which frequency.
In addition, investigate if your query are appropriate ones that is don't return thousand and thousand rows.
