Open an SSH connection to Oracle VM Manager.

Run the following command to connect to the MySQL database:

# mysql --user='username' -p -S /u01/app/oracle/mysql/data/mysqld.sock

Specify the password for the user at the prompt.

Run the following command to change to the ovs database:

mysql> use ovs

Run the following statement:

mysql> select associatedObjectID, description from OVM_EVENT where type=
'server.upgrade.in.progress.'  -> ;

The statement returns an object ID for the instance of Oracle VM Server to which the event applies, as in the following example:

+--------------------+------------------------------------+
| associatedObjectId | description                        |
+--------------------+------------------------------------+
|                303 | Server: server_name, is being upgraded. |
+--------------------+------------------------------------+
1 rows in set (0.00 sec)

Run the following statement, substituting object_ID with the object ID that was returned with the preceding statement:

mysql> update OVM_EVENT set acknowledged=1 where associatedObjectId=object_ID and type=
'server.upgrade.in.progress.';

The statement acknowledges the event and displays a message such as the following:

Query OK, 1 row affected (0.01 sec)
Rows matched: 1  Changed: 1  Warnings: 0 

Run the following statement to confirm the server.upgrade.in.progress. event is acknowledged:

mysql> select acknowledged from OVM_EVENT where type='server.upgrade.in.progress.';

A message such as the following displays:

+--------------+
| acknowledged |
+--------------+
|            1 |
+--------------+ 

Exit the database.

mysql> exit
