RE: How to use Export Transportable Tablespaces

Message-ID: <F001.002AE02C.20010207110611@fatcity.com> 






This process was repeated monthly.  So, all references in the target database were 
dropped each time the process was performed.

Thanks a whole bunch Tim, but one final question.



Why did you drop the tablespaces


<drop tablespace stage_haines_data including contents;
<drop tablespace stage_haines_index including contents;

Filtering attachments is a reasonable precaution, I guess.  Here is the
pasted script:

# It needs two parameters as "From DB" and "To DB".

#

# Created :  2/16/2000  by Pawan Sanwal (Whittman-Hart)

#

# This script need to run from the same machine where both databases exist.

#

# Exit if not all the arguments supplied.

  echo ;


  echo "Usage :  transport.sh <From Stage Oracle SID> <To Cars Oracle SID>";

fi



#

# The tablespaces should always be transported from Stage to Cars databases.
