How to export-import Oracle data
Usually, the backup function for Oracle databases in a lot of large companies is managed by a DBA, so SamePage
administrators do not have to worry about it. But in case you are using a stand-alone Oracle 10G XE, you can simply use
the Oracle export utility to take regular database backups.
For Export
You simply need to run the following command at the command prompt of the machine where you have Oracle installed:
exp username/password file=samepage.dmp log=backuplog.txt statistics=none
where
username/password is the database username and password that is used by SamePage (Note - this should match
username, password in cm.xml file under <SAMEPAGE_INSTALL_DIR>/tomcat/conf/Catalina/localhost/)
samepage.dmp is the name of the file where you want the SamePage data to get backed up.
backuplog.txt is file into which you want to redirect the logs
You can also copy this command into a .bat file and have it run at regular intervals.
The dmp file should be securly stored so you can import it back to re-create the schema in case of a database crash.
For Import
If you are importing the schema to another database user, you should first create that database user and give it the
required privileges. Oracle allows only system user to import one schema's objects into another.
So if the data was exported from User1, you can import it into User2 with the following command:
imp system/systempassword fromuser=User1 touser=User2 file=samepage.dmp log=implog.txt
where
system is the Oracle's 'system' username and systempassword is 'system' user password
User1 is the original DB user from where the data was exported
User2 is the new DB user into which the data is being imported
samepage.dmp is the exported database dump file
implog.txt is file into which you want to redirect the logs
