As for throughput, I get about 20GB to 25GB per hour across 1Gb switched
LAN (full duplex). This is going from Sun 450/4500/6500's and RS/6000
H70/H80/S7A/S80's to TSM servers on RS/6000 H70's or S80's. Sounds like
400MB per hour is what you're getting - I'd look first at network
interface and switch setup. If you are connecting to a switch and not a
plain hub, you may need to force both the switch port and the NIC into
full duplex mode. If one is full and the other half, you will see 1
collision for every packet sent - so total collisions will be half of
total packets sent/received. If you show no collisions at all, then both
are talking full duplex, if a low number of collisions, both are half
duplex. My largest single backup is a 160GB Oracle database, it takes
about 6 hours to complete.

As for the module leaking memory, why are you unloading it? Are you
running a server-based schedule? If so, then leave the DSMC module
loaded with "load dsmc sched" and it will wait for the next day's
scheduled start time to initiate another backup.

Hope that helps,
MO

Hi,

I'm new to the TSM environment. I need help on the Netware backup.
Currently, we are running Novell 4.11 with SP9. On the TSM side, TSM
server
is 4.1 and is running on RS/6000 with AIX 4.3.3.
The client code I have is 4.1.2. When the last time I tested the Novell
TSM
client 4.1.2, I ran into couple problems.
First, When I first tried to backup the 2GB SYS volume, it took 2 hrs
and it
only backup 800MB. I then stop the backup test. The biggest problem I'm
facing now is that we have a volume that is about 100GB in size and
has a
lots of directories and small files. I can't imagine how long will it
take
to backup a 100GB volume.
Secondly, after I have finished the backup and when I unload the TSM
client
on the Novell console, I got an error message that a certain small
amount
memory could not be free up. My concern is that if I run the TSM backup
on
Novell nightly, if the TMS client does not release those memory this
will
cause memory leak on the Novell server and will cause the Novell server
crash sooner or later. Anyway, the Novell server that we have is a three
years old Compaq proliant 2500R which we about to retire, it has a 3com
GBit
Ethernet card with 1 GB of memory. SYS-2GB, VOL1-100GB, VOL2-35GB.

Any feedback or solution will be appreciated.

Thanks,

Tuan

Subject: Netware client code


Last week, Netware code 4.1.2.16 was available on the Tivoli website for
download, along with the 4.1.2.13 code.  After looking at both README
files, we elected to go with the .16 level.  I went back today to
download
it, only to find that it is no longer there; only .13 remains.  Does
anyone
know what happened, or where I can go to find out why this was removed?
This may require some rethinking on our end, but it would be helpful to
know the reasons behind the removal.

Thanks!
