Re: question about brms network backups -- MIDRANGE-L

Adrienne,

I'd still take a look at the bandwidth requirements very early in this 
process. To transfer 100 GB of data over a T3 at 45Mbps connection will 
take over 5 hours. It will take over 151 hours over a T1 at 1.5Mbps. A 
data replication solution would start journaling on systemA , make a tape 
copy, restore the tape copy, and then send all of the changed data to 
systemB and applies the changes to the files as they change. The key is it 
only send the changes, so the data transfer is much less.

We do have BRMS in use here, but I'm not familiar enough to say whether or 
not it would work to do what you want. Certainly you could do a save to a 
save file, FTP that to the backup, and save the save file to tape.

I talked to our BRMS admin, and he thought that if you had an IP attached 
tape drive, you could do save to a tape drive at the remote site. BRMS 
networking would allow you to share the tape drive between both systems. 
He wasn't aware of a way to save from a tape drive directly attached to 
the remote system. 

Good luck, 
Steve

question about brms network backups

 Steve,

Thanks so much for your response, and no we are not using a data
mirroring package. 

I am going to try to explain the scenario more clearly, keep in mind, we
are relatively new and self-taught, self-trained, on the iSeries, but
between the  4 people in my group, we each have at least 20 years
experience in IT each (now that I think of it - I think we may almost
have 100 years collectively).

Here goes - We have iSeries Production machine (A) at our location.
This is a 680 GB machine that we use 60-70% of the disk space regularly.
We have a disaster recovery/backup machine (B) that is 215 GB and that
is located 50 miles away.  Attached to B is a tape drive.  We would like
to have machine B (the remote machine), read machine A and pull the user
data to be backed up onto the tape drive attached to B.  Ideally, we
would use BRMS to accomplish this task.  At this point - our main backup
concern is our user data, secondary is the system backup.  I am told we
are not concerned about bandwidth at this moment.  This issue is
currently in the process of resolution.  So, is this feasible to do with
BRMS or some other means?  Anybody have any 'how to' advice?

Thanks,

Adrienne McConnon

subject: Re: Call iSeries program from C# program

   Thanks , its working great except for one thing....
   I'm testing this out in a web application as opposed to a Windows
GUI.

   I have the iSeries/As400/System i program being called in the
Page_Load
   event of the initial web page that opens (default.aspx).  It seems
that
   the Page_Load event fires no matter what happens (ie. clicking a
button). 
   I even added a class level boolean variable and change it to false
after
   the programs run.  If I click on a button (that has no code for it
yet)
   the Page_Load event fires, and then the Click event for the button.
When
   the page load runs, the boolean variable is automatically reset to
true
   and the AS400 programs are called again.

   Any way that you know of to get the programs to call only on the
first
   time the page is opened?

   Thanks.

subject: question about brms network backups

Good morning!

Our scenario is - we have a new iSeries in the office, our BR machine is
now located miles away in a remote location.  The tape drive is attached
to the remote BR machine.  We would like to backup the new machine to
the remote tape drive/remote iSeries.  The 3 units are networked and
bandwidth is gong to be increased.

Is it possible to use BRMS to backup up the new machine to the remote
tape drive and or remote iseries?

How would one do this?

Thanks,

Pete,

I'm not familiar with the 6400 but we use the basic UPS for our HP
lasers and smaller.  We use the same UPS for some big honkers (Canon's
and Ricoh's).  We even use the same for our twinax printers because
spikes from power outages and *Immed restarts were blowing cards in
them.

Just as an aside, is there such a thing as a UPS designed for a 
printer?  These folks have frequent power outages and surges (small 
island in S.E. Alaska).  The System i and x servers are well protected

and the twinax connected printers seems to weather these power outages

OK but this Ethernet attached printer seems to have the most problems.
If there is such a thing as a UPS designed for a line printer, these 
guys would be candidates.

I' sure you told them to turn the printer off and back on ???
The power on sequence would reload any micro code needed for comm.

You have a ethernet card failure due to power surge.

I have ended the printer writer, varied off and on the device and

ends abnormally with the following message in the job log:

subject: Re: How To Configure Console Address

Hi:

(I think the address to the original question depends on the device.)

Anyway, are you sure about the console having to be port 0 switch 0? We
have two 3196 devices set up to use as consoles. One is port 0 switch 0
and is on my desk, the other is port 0 switch 3 and is in the Computer
Room.
(Both devices are on Controller 6.) Yet, we have for years used the 0/3
device as "the" console, in some cases not even having the other one
connected for long stretches of time. I have not encountered any
function I could not do from the 0/3 terminal.

Looking for education. If there is a real difference, I might swap the
two.

You need to go into setup mode and change the address of the device to

zero.

Promary console is port 0 and address 0 and secondary console is

Now the display of the primary console has been broken down and I 
need to replace the secondary console as a primary. I tried to 
pulgin the cable which is connedted to the primary and turned on the

console, but the console is recognized as port 0 and address 3.

Does anybody know how to configure the address on the console? or do

subject: Re: question about brms network backups

Before you jump into this remote backup possibility, check here to see
how large a connection you need to transfer your data:
http://www.ibeast.com/content/tools/band-calc.asp
We were interested in replicating tapes between our primary and backup
site, but the bandwidth made in impractical for us.

Are you using a data mirroring package? What we are trying to do is to
run the backups on the remote system. We will embed a command in the
data replication journals that tells the backup system to stop applying
journals to the backup system, and start the backup. When the backup is
complete, it tells the backup system to begin applying the journaled
data that hasn't been applied.
