Oracle streams and supplemental log problem

Hi all,

This can be a vague question, so I'll try to make it as clear as possible.

On a customer we have 3 2-node RAC databases (11.1.0.7 on HP-UX), one is
source and the other two are destinations of Oracle Streams replication.

Today, out of the blue, we saw this message on the alert log

"Alter database drop supplemental log data"

Since Streams uses supplemental log data to do replication, it stopped
working right there... problem is I don't know why that command was
executed.

The previous alert entries are regarding a job with problems, the job is
related to the tuning pack of gridcontrol ("SYS.PRVT_ADVISOR",
SYS.DBMS_ADVISOR)

How can I know why that command was executed and who or what made it?
Any ideas?

Thanks in advance, and best regards.
