How to backup the Datafile in the hot method

Hi All,

In the hot method,I write the the script code as below:
Step 1) Alter tablespace tab_name begin backup
Step 2) oCopy Data file to target location
Step 3) Alter tablespace tab_name end backup

But,When step two isn't finished, step three is already executed,My Oracle Server is install in the NT mode,How to deal with it?

Thanks!

How are you running these commands?
Is the OCOPY run as a HOST command?

This is a script for performing an online backup of the Oracle database. The script can be run after setting the site-specific values of the different environment variables listed below. It has been tested on all versions of Oracle, up to 8.0.6, installed on Unix platforms.

This script is generic and can be customized to suit your environment.

Hi,Tony and Admala

My Oracle Server is running under the NT enviroment , and my script is executed in the host machine.

Thanks!


------------------------------------------------------------------------
In the hot method,I write the the script code as below:
Step 1) Alter tablespace tab_name begin backup
Step 2) oCopy Data file to target location
Step 3) Alter tablespace tab_name end backup

But,When step two isn't finished, step three is already executed,My Oracle Server is install in the NT mode,How to deal with it?

Are you running everything from a single command file?
I have just tested running from a single SQLPLUS script with multiple HOST OCOPY infile.dat copy.dat commands and each waited for the previous to finish.
