Database Software

Hello everybody,

Sometimes i got error messages on the backup of 2 databases (Oracle 11g R2). The backups are realised by dataprotector 6.1
When i execute the backup manually through dataprotector everything is fine.

In the event logs of dataprotector i can see the fails backups and there is an action adviced :
"reduce the number of channel to be egal with the simultaneous parameters in the backup"

Here is the rman script used by dataprotector :

run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SITGTD,OB2BARLIST=Sauvegarde TD)';
backup incremental level <incr_level>
format 'Sauvegarde TD<SITGTD_%s:%t:%p>.dbf'
database;
sql 'alter system archive log current';
backup
format 'Sauvegarde TD<SITGTD_%s:%t:%p>.dbf'
archivelog all
delete input;
backup
format 'Sauvegarde TD<SITGTD_%s:%t:%p>.dbf'
current controlfile;
}


I see only one channel described and the simultaneous parameters is set on 2.

Any one has an idea ? Is there anything i can change in the rman script ?

Thanks you.

David
