BPEL Console fails with "ORA-28001: the password has expired"

I recently came across an issue while accessing BPEL console, and was shown a SQL Exception "ORA-28001: the password has expired" on the BPEL console page. On checking the Oc4j_soa log files found the same error:

java.sql.SQLException: ORA-28001: the password has expired
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:138)
at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:316)
...
...

On debugging further found that the orabpel and oraesb account passwords had EXPIRED on the Fusion DB. That was by design and implementation of the Oracle DEFAULT profile to which the users belonged. So to fix the issue the user accounts had to be unlocked/unexpired so that status showed as OPEN.

You can also check with your DBA team to see if the DEFAULT profile can be changed to allow unlimited days for a password and unlimited attempts at logging in (before account is locked).
