Hi all,
I'm really newbie about Oracle backup operations. I'm really new in this world and I need to know how to backup a DB schema and restore it in another machine under another schema name.
I cannot afford any mistake since I'll be doing this in our customer site, an making a small mistake could be the last one
I don't want to sound offensive, but doing this in MySQL is really easy, like this:
in server one:
$mysqldump --user=user --password=password db_to_backup > bc_name.sql
-after transfering the sql script to another server
in server two:
mysql>create database db_to_restore;
$mysql --user=user --password=password db_to_restore < bc_name.sql
I need to do the same using Oracle, I read some documentation but I'm still unsure how to do it:
First: What's the equivalent of MySQL database in Oracle? tablespace?
Second: I think these are the steps to get a backup
mkdir /opt/oracle/dumptmp/ CREATE OR REPLACE DIRECTORY dumptmp AS '/opt/oracle/dumptmp/'; expdp user/pass@tablespace directory=dumptmp dumpfile=dumptmp:full.dmp logfile=dumptmp:full.log full=y
Third: Then I move the file "full.dmp" to the other server, but I'm not sure how to restore my backup file full.dmp into a new tablespace with a different name to the one it the backup was gotten from:
SQLPLUS>create tablespace ts_something;
then I'm not sure how to proceed from here. Please advice me how to do it using command line commands since my customer does not have GUI tools intalled.
Thanks a lot!
