ORA-19511 Vendor specific error: Cannot find requested element ERR(-2)

Applies to:

(+ASM_FRA/ractest/autobackup/2009_02_19/s_679226354.411.679226355)
ORA-19601: output file is backup piece (c-3183778111-20090219-02)

Cause

HP data protector media manager issue. The HP data protector software causes the error. There
is a delay between backupsets which are send to the HP cell server. If the delay is to long the hp
cell server closes the session. The client did not recognise the close and fails with the transfer
of the data.

Cause justified by customer.

Solution
To implement the solution, please execute the following steps:

A solution for me was to set in the configuration file:

On Unix Plattform: /etc/opt/omni/server/options/global
On Windows Plattform: C:\Programme\OmniBack\Config\Server\Options\global

the parameter SmWaitForNewBackupClient to 2 minutes:

# SmWaitForNewBackupClient=WaitForInMinutes
SmWaitForNewBackupClient=2

There are further hints about the SmWaitForNewBackupClientSec parameter. Maybe this parameter also
helps.
# SmWaitForNewBackupClientSec=WaitForInSeconds
