Oracle Automatic daily backup scripts

Because a backup script for Oracle needs to be written recently, Oracle's data backup is not backed up directly using binary tools like MySQL, and data backup on Oracle needs to be configured so that normal data backup scripts can be configured. So you need to do some configuration before Oracle backs up your data.

First, because of Oracle's 11g start-up feature, empty tables do not allocate tablespace so in the backup script I use the EXPDP tool for data backup, before the backup begins, you need to export the Oracle data Pump directory with the DBA account first to specify and authorize read and write, and then modify the directory of the group, Operation is very simple, is a number of EXPDP data pump operation, this has been explained before, here do not do a description of the length, you can see: http://jim123.blog.51cto.com/4763600/1941618, after setting up a good dpdata1 directory, It is important to also modify the genus of the dpdata1 directory, otherwise the data file exported using EXPDP cannot be written, depending on the group modification permissions defined at the time when Oracle was installed

[Email protected] ~]# chown oracle:oinstall/data/backup/oracle_backup

After modifying the above steps, and then the Oracle user under the Bash_profile configuration file in the installation of the environment variables defined in the script, in the definition of the execution time of the script can be, the implementation of the script is relatively simple, as follows:
