Thanks for your thoughts.
The 10 x slower thoughput happens only with 7.3.3 Networker server and the
mix of Oracle, Windows, NMO, Networker client version on that one server.
With Networker server 7.2.1 all (Networker) clients were happy.
With Networker server 7.3.3 we have one unhappy NMO backup. Many dozens
happy NMO backups.

RE: [Networker] NMO
running slowly with 7.3.3 Server
Maybe another one being in reducing amount of parallelized dbf
files processing using "fileperset 1" in backup statement like
(...)
backup full filesperset 1 format '%d_df_%u' database;
(...)
Can decrease oracle server load in case of bottleneck
being oracle server not able to send data fast enough
to backup server.
Another hint to consider lan connection. Maybe is lan
link saturated causing perf drop down.

Thanks for the suggestion.
Problem is that multiple channels require Enterprise Edition

Hi Matthew,
Thanks for taking the time to respond.
It was taking 10 hrs with NMO 3.5. EMC suggested we upgrade to 4.1.
Here's the rman script...
@@connect_jde
run {
set command id to 'jde';
allocate channel t1 type 'SBT_TAPE'
parms 'ENV=(NSR_SERVER=ukrdgux900,
NSR_DATA_VOLUME_POOL=oracleLTO)';
backup full
tag 'ukrdgap086 latest hot'
format 'DBFULL_%d_%u'
(database);
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
backup
format 'ARCHLOG_%d_%u'
(archivelog all delete input);
release channel t1;
}

RE: [Networker]
NMO running slowly with 7.3.3 Server
That's interesting especially since the legato networker client is used
to just start the NMO proccesses, after that, it does very little. I
don't believe NMO 4.1 is certfied for Oracle 8.1.7.
What does your RMAN script look like?

Hi,
Client config: Windows 2000, Networker Client 7.2.2, Oracle 8.1.7, NMO
version 4.1 Networker Server: Solaris 9, Networker 7.3.3
A "hot" Oracle backup of about 70GB is taking around 10 hrs since
upgrading to 7.3.3 on our Networker server. This is clearly unacceptable
and we are getting very little feedback from EMC
When we were on Server version 7.2.1 it took about an hour. There was no
change other than the upgrade to 7.3.3
Anyone else with similar setup experienced similar degradation?
Bob
