I think I've seen the data guard broker do things like this.

This is almost certainly coming from some sort of automated process.  The
database is only opened by something else once the database is mounted (and
I'm trying to rename my database files!!).

10.2.0.4 on RHEL 5

 

I'm in doing some datafile renaming for my own sanity.

 

The thing is, once I mount the database and rename a few datafiles, I start
getting messages that the database is open.

 

ERROR at line 1:

ORA-01511: error in renaming log/data files

ORA-01121: cannot rename database file 2 - file is in use or recovery

ORA-01110: data file 2: '/u01/oradata/db_name/undotbs01.dbf'

 

SYS@remgt> alter database open;

alter database open

*

ERROR at line 1:

ORA-01531: a database already open by the instance

 

 

How would I go about figuring out what or who is opening the database?  This
has happened repeatedly.

 

I have contact the system administrators and they can't think of any
monitoring software they have configured to do thiat.
