Hi,
You should get in touch with your backup admin problem most probably at your hardware end…

I have a performance problem with the Oracle database restore using tsm tdpo for oracle. When I test the network speed from tsm server to database server using ftp I have a speed of about 85 MB / s and when I do restore only 6mb / s.
Config files:
dsm.sys:
SErvername server_a
COMMMethod TCPip
TCPPort 1500
TCPServeraddress 10.200.4.109
passwordaccess generate
managedservices webclient schedule

servername tdpo
commmethod tcpip
tcpport 1500
tcpserveraddress 10.200.4.109
nodename bg01003db225-ora
asnodename bg01003r3n1-ora
passwordaccess generate
passworddir /home/oracle/pass/
include /orc11_db/…/* oramgmtclass
diskbuffsize 32
txnbytelimit 10G
tcpwindowsize 512

tdpo.opt
racle@bg01003db225 [/usr/tivoli/tsm/client/oracle/bin64] $ more tdpo.opt
***************************************************************************

*TDPO_MGMT_CLASS_2 mgmtclass2
*TDPO_MGMT_CLASS_3 mgmtclass3
*TDPO_MGMT_CLASS_4 mgmtclass4
———————-
command for restore:
run{
ALLOCATE CHANNEL tdpo1 type ‘sbt_tape’ parms ‘ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)’;
set limit channel tdpo1 kbytes 2097150 maxopenfiles 16 readrate 500;
RESTORE DATABASE UNTIL sequence 684338;
RECOVER DATABASE UNTIL sequence 684338;
release channel tdpo1;
}
I changed the diskbuffsize parameter to 32,256,512 nothing changes, the speed of the restaurant is 6mb / s.LTO Tape is IBM TS4500
