Long runtime when using brarchive verify option

Hi everyone,

we have a problem concering the runtime of our Backups. The backup is running fast enough (3h for 320gb), but when we use the verify command for the archivelogs it took 13hours for the redolog processing in the last run. Any suggestions what might cause this long runtime?

The command we use is

BRARCHIVE will be started with options '-U -jid ALLOG20100614200000  -c force -p initFEP.sap -sd -w use_rmv'

The system is a ECC6.0 running on 64Bit Linux on Oracle 10.2.0.2. The BRtools Version is 7.00 (48).

Thanks in advance

Marco
