Problems with Failure of a Running Service When the Schema User Password Expires

An Oracle SOA Cloud Service instance can fail suddenly and issue password expiry error messages.

This failure occurs because the user password for the infrastructure repository schemas is set to expire in 180 days after an Oracle SOA Cloud Service instance is created. You get the following error messages:

Received exception while creating connection for pool X: ORA-28001: 
the password has expired

java.sql.SQLException: ORA-01017: invalid username/password; logon denied

Another symptom of this problem is that a patch precheck, restoration, or scale out operation may fail.

Note:

By default the schema password is set to Weblogic Administrator password during the provisioning of the JCS instance.

To correct this problem, follow the steps in Change the Database Schema Password Manually.
