RE: How to refresh

2003-12-16 Thread Pandian, Thiru
For this kind of situation I do normally like this 
Store all table names in single file. 

Exp constraints=n triggers=n indexes=n tables=`cat tables.lst`
file=table_data.dmp grants=n 

Import the full file or by  fromuser, touser option.

I need to do a refresh of a test database using production data.  We use
import for this.  In the past we have always dropped the schemas (4 or
5), recreated the schemas, and then did a full import with ignore=n.
This time the user does not want to lose any of the new functions and
procedures that are in test, but not in prod.  Instead, they would like
to just refresh the table data.  Last time we tried this we had all
kinds of trouble with functions, triggers, constraints, etc... and ended
up doing a full import.

Is there a tried and true way to just refresh the table data without
losing anything else and without having all the problems with triggers
and constraints?

Thanks!
Ron

RE: Changing Character Set from WE8ISO8859P1 to UTF8

2003-12-13 Thread Pandian, Thiru
I have upgraded the database from 8.0.5/8.1.7 to 9.2.0.4 and changed
character set using alter database character set.
It will work without any problem. Go for it.

I am in the process of planning our upgrade for our 8.1.5 database to
8.1.7.4.  This is the first step in upgrading all my databases to
9.2.0.4.
As part of this upgrade I am changing the character set from
WE8ISO8859P1 to
UTF8.  Has anyone done this change using the ALTER DATABASE CHARACTER
SET
command?  If so, was there any problems?

Thanks,
