Resetting Schema Password

Question

Hi Friends,
I have a source database 'A' (oracle9i) and destination database 'B'(oracle11g). The schemas are exported from A and imported onto B.
Currently B database have different Password for schemas than that of A.
I require to set all the Passwords on B database as is in the A database.
For that I plan to get the password values from A and reset accordingly on B database. For which I'm going to run the query
select username, password from dba_users; (on A, get the values and reset on B).
Is this the right procedure to set the password as is from A to B.
Thanks
KSG

You might like to put the following into a scipt and run it on the source DB.
Copy the generated output to the destination host and run it on destination DB.
Create/Change $WO/reports location and $WO environment variable first, or edit the script.

PS.
I use the above - to save the passwords in use on Dev & Test DB's - before wiping and refreshing them, with a current copy of the Production.
Users often have different passwords, (for the same schema name) depending on the Dev/Test/Prod status of a database.
PPS. I reccommend you upgrade the production DB to 11G - ASAP.

Vin.
