Problem in scheduler - Oracle 10G

Question

I have 2 databases connected through a connected user link.
Example:
1) TEST schema in db1 and TEST schema in db2 connected through DB link LINK1 which is through connected user (Username and password not provided while creating DB link since they have same username and passwords).
2) I create table T1 in TEST@DB1 and synonym T1 in TEST@DB2.
3) I create a procedure P1 in TEST@DB2 which inserts into T1.
4) I run the procedure P1 in TEST@DB2 and it successfully inserts into T1.
5) I create a job through dbms_scheduler.create_job and schedule P1 to run every 1 minute
6) Through the scheduler it gives an error saying "Invalid username/password" while accessing T1.
7) Without connected user it work fine.
Any idea anyone?

Answer 1

it might be a requirement. To be able to use db_links in stored procedures ab/or scheduled db jobs you need a db_link with a defined user/pwd.
You already found the workaround for your problem. Just set up the db link correctly. Is there a reason to do otherwise?
