Dear friends,
Just wanted to know is there a way to get the password of the schemas that i want to use in the export command. Cause we have created a script file where we are writing a batch file inside that we are passing the schema name from java as a parameter. I want to capture the password for the schema and i want to pass it to the script, please help me out.

Regards
Joe

For export, I don't think that's necessary. You connect as SYSTEM and select the USER you want. Or, user_name.table_name for all tables you want to be exported.

Anyway, I don't think you can retrieve a password directly but if you really need to access the schema as its owner, here's what you could do:
1. Connect to the db as a DBA
2. Look up the hash value of the current password for user_x.

Code: [Select all] [Show/ hide]

SELECT password FROM dba_users WHERE username='USER_X'

3. Reset the password so you have access. Let's say we want the password to be set to the username

Code: [Select all] [Show/ hide]

ALTER USER USER_X IDENTIFIED BY USER_X;

4. Run the batch or whatever actions you might want to perform.
5. Reset the password of the user.

Code: [Select all] [Show/ hide]

ALTER USER USER_X IDENTIFIED BY VALUES 'the_hash_value_returned_in_step_2';

HTH,

Perfect answer.

Just remember to capture the hash value returned in step 2, and store it somewhere, else you wont be able to reset it.

Vikas.
