Extremely slow SAP backup

[collective7]

SAP running on Sol 8 .. on archive log mode... due to tight $$ they dont have the hot backup agent, its all done via the DBA's homegrown script. Bacup gets going but SLOW! So far errors seen are:

Cannot write to STDOUT Errno=32 Broken pipe

in the bpsched log

amy ideas appreciated

How are you doing the backup?
Brbackup to disk, then copy to tape?

No, backs up straight to tape.

So you shutdown sap/oracle before each backup?

update:

the issue was traced to faulty switch configuration. we had to eliminate everything before getting the networking guys involved.

all my life i have stayed away from autonegotiation of link speed and mode and such. I always hard coded for 100/full and i asked for the same on the switch. well, turns out this 10/100/1000 switch likes to negotiate.

thanks for trying to help!
