RMAN backupsets to disk - how to parallelize?
Is there any way to utilize Oracle RMAN backup parallel features via BR*Tools when performing backup to disk?
Platform: Windows if it is relevant, Oracle 10.2.0.4.
The only way I found so far is to use exec_parallel parameter in BRTools profile and in this case parallelizing done via starting n processes of RMAN in parallel when each makes backup of separate datafile. The aim is to do something with BRTools parameters to get parallel option 'inside' RMAN (equivalent of "RMAN> CONFIGURE DEVICE TYPE disk PARALLELISM n;").
The other part - how to parallelize offline redo log backups for RMAN backupsets? Even having exec_parallel parameter set to >1 only one process of BRARCHIVE is processing all offline redo logs serially.
BR*Tools parameters which I changed from baseline:
backup_mode = full
backup_type = online
backup_dev_type = disk
archive_function = save_delete
disk_copy_cmd = rman_set
rman_compress = yes
rman_cross_check = arch_force
exec_parallel = 4
