Hi,
after upgrade from Solaris 08/07 to Solaris 10/09 BRBACKUP is 1,5 - 2 slower.
Have you got any idea?
BRBACKUP is invoked as:
brbackup -p initSID.sap -u user/password -d disk -t offline -m all -c force -k yes -e 24 -l E
and initSID.sap:
backup_mode = all
restore_mode = all
backup_type = online
backup_dev_type = disk
backup_root_dir = /stage_prod/SID
stage_root_dir = /stage_prod/SID
compress = yes
compress_cmd = "compress -c $ > $"
uncompress_cmd = "uncompress -c $ > $"
compress_dir = /oracle/SID/sapreorg
archive_function = save_delete
archive_copy_dir = /stage_prod/SID
archive_stage_dir = /stage_prod/SID
tape_copy_cmd = dd
disk_copy_cmd = dd
stage_copy_cmd = rcp
cpio_flags = -ovB
cpio_in_flags = -iuvB
cpio_disk_flags = -pdcu
dd_flags = "obs=64k bs=64k"
dd_in_flags = "ibs=64k bs=64k"
saveset_members = 1
copy_out_cmd = "dd ibs=8k obs=64k of=$"
copy_in_cmd = "dd ibs=64k obs=8k if=$"
rewind = "mt -f $ rew"
rewind_offline = "mt -f $ offline"
tape_pos_cmd = "mt -f $ fsf $"
tape_size = 1200M
exec_parallel = 9
tape_address = /dev/rmt/0mn
tape_address_rew = /dev/rmt/0m
volume_archive = (SIDA01, SIDA02, SIDA03, SIDA04, SIDA05,
SIDA06, SIDA07, SIDA08, SIDA09, SIDA10,
SIDA11, SIDA12, SIDA13, SIDA14, SIDA15,

SIDA21, SIDA22, SIDA23, SIDA24, SIDA25,

volume_backup = (SIDB01, SIDB02, SIDB03, SIDB04, SIDB05,

>>exec_parallel = 9
Looks like you are executing 9 parallel process.

>>backup_root_dir = /stage_prod/SID
Is above local filesystem or network?
>>compress = yes
You are also performing compress while disk backup. to folder compress_dir = /oracle/SID/sapreorg

Hi,
Please check these things before up-gradation the backup size and the backup time and the backup type
As you have upgraded the O/S kindly upgrade the BR tools.

Hi,

same database size, same number of datafiles, ecc. befeore and after Solaris upgrade.
>As you have upgraded the O/S kindly upgrade the BR tools.
try with same BRTOOLS version release and with newer release
Regards.
Most probably you also have to adjust Solaris kernel parameters.
Did you do so?
There should be SAP notes about it.
