Oracle RAC: Unknown CORBA exception

[DanMarch]

Hi, 

Anybody known what a problem is associated with this message?

RMAN-03009: failure of backup command on ch0 channel at 02/12/2009 09:46:13

procMsg: ORA-19506: failed to create sequential file, name="BE_1ck75rj4_1_1", parms=""

procMsg: ORA-27028: skgfqcre: sbtbackup returned error

procMsg: ORA-19511: Error received from media manager layer, error text: Setting job level error from script output to (0xe0001405)

BEError(0xe0001405) Unknown CORBA exception. Unable to contact the media server. Confirm that the Backup Exec Job Engine service is running on the media server.

I have two subnets, the nodes of Oracle RAC are 172.16.10.0/28 and media server is 172.16.10.16/28.

I check Symantec docs related with Oracle and RALUS agent.

Backup Of an Oracle database fails with an error "Unknown CORBA exception. Unable to contact the media server" if Backup Exec is installed on a Windows Server 2008.

Exact Error Message
Final error: 0xe0001405 - Unknown CORBA exception. Unable to contact the media server. Confirm that the Backup Exec Job Engine service is running on the media server.
Final error category: Resource Errors

When Backup Exec for Windows v12.x is installed on a Windows Server 2008, backup of an Oracle database will fail with the above error.
Oracle database can be local on the media server or remote on any Windows or Linux server.
The problem is with the failed initialization of the Common Object Request Broker Architecture (CORBA) on the media server.

Ensure that the "::1 localhost" line is present in %Systemroot%\system32\Drivers\etc\hosts file.

Ensure that bit 5 (The 6th bit counting from the right) of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents registry key is not set (if it exists).

In our case the value 0x000000A (simple A in the regedit) for this key resolved the problem, the port 5633 listen after reboot and backup executes normally. The sugested value 0x00000FF (FF) dont works for Backup Exec 12.5, as sugested in Microsoft documents about to totally disable IPv6.
