a few days ago we had this configuration:
OS: HP-UX 11.31
Oracle 10.2.0.4 database
with brtools 7.10 Patchlevel 30
We are using Symantec Netbackup for Backup.
In the util-file we are setting this extra rman-parameters for backup:
rman_channels = 24
rman_filesperset = 4
rman_RATE = 5K
(i know, that rman_rate shouldnt be alright, but it works for us to slow a little bit the speed)
The backup was working fine with about 100mb/s.
After upgrading to Oracle 11g + brtool 7.20 Patchlevel 10, the backupporcess takes a veeeeeeeery long time.
We saw in the netbackup-gui that speed ist about 5kb/s ...
I think that the rman_RATE parameter is now (with 7.20) working correct.
Does anyone have similiar troubles after upgrading to newer brtools (and/or Oracle11g) ?
I doesnt find any bugfix/release-notes, that the "function" of rman_RATE was changed?
When we changed the rman_RATE to 100m the backup is working fine.
