Auto refresh

[Vickdu]

Hi Guys

My Auto refresh is not working I have the read/write map and the crew that I support have a read only map.

The problem is that the read only map sometimes does not update and the crew does not pick up alarms or a device going red.

What might be the cause and what should i try.

best regards
Vickdu

Hi there, which product are you currently using?NNM or VPO or both?
Anyway, you should probably use a script to synchronize every map, perhaps, after the prime shift, it 'd only take a few minutes and would keep your maps consistent all the time.
This can be acomplished by copying the NNM's rw map to the rest, the users must close their maps for this period of time, but for 15 maps as an example it should only take about 5 to 7 minutes, no more than that...

Hope this helps,

First of all, I would put a paging solution into place, with the defacto in the industry being TelAlert; and, you can get more information about this product here:

http://www.vytek.com/products/urgentmsg/telalert/index.asp

If you have operations personnel set up to be "glass watchers," so to speak, with no automated solution, such as TelAlert, in place to send e-mails, pages, voice messaging, loud speakers, sign board messages, etc. to the correct personnel, when the truly critical alarms are perceived, e.g., OV_Node_Down, etc., that would take care of your worries without making any modifications to the management system, to make up for the fact that the read-only map is not current and/or synchronized.

With that being said, and cheers for out-of-the-box functionality, then you can make the decision, as far as modifying the default configuration of OpenView, if you choose to do so at all.

Look at the $OV_REGISTRATION directory, and you will find several files, one of which contains the menu pick item for the map's refresh option. This will include the information that you would need, as to what is done in the background, when this menu selection is executed.

Then, set up a cron entry - or the Windows equivalent, "Scheduled Tasks" - so that the refresh is automatically done on a periodic basis, so that the map is as current as possible, without causing an undue amount of overhead on the management system itself, when map synchronization is taking place.

Hi vlan52

Im using NNM.How would you go about implementing that script I dont have even a clue of how to do that!
What should the script look like etc etc.

Sure, no problem, here goes the script I'm using:

#!/usr/bin/ksh
# ovw_map_copy script
# Purpose: Automatically copy the default NNM map to all ITO users
# Argument: None
# Dependency: None
# Output: File $UNCOPIED_LIST contains a list of maps that couldn't
# be copied because user was logged on at the time the script
# was last executed
# Return value: 0 -> Success
# 1 -> Error

The read-only map can have "auto-refresh" if you use cron to automate the command that is used in the OV registration files, which is associated with the menu selection in the read-only map, which manually refreshes the map.

At that point, you would only need to decide on the interval, and then use cron - or, scheduling an automated action, if you are running the management apps on WINNT... -at the desired rate for refresh, with that being four times per hour, or whatever is deemed most appropriate, given the specific technical requirements that drive the use of these management applications.

Good idea Mike, I'll take a look into the $OV_REGISTRATION path and see if using that file makes NNM's life easier.

Hye

I have a big problem, I find a correct file in $OV_REGISTRATION: there are f.refresh_map . But i don't find where I can modify this function.

By avance Thanks

Hi alcanet

Did you manage to find the registration file that refreshes the map and how to modify it?

Hi Vickdu, regarding your initial question, refreshing the read-only maps is not required to update STATUS, since the status of every symbol, object in every submap is updated automatically.

What you would not receive/get, are updates on topological events (addition/deletion of symbols), under RO maps, then you should click on Refresh, to retrieve those changes.

Now, if you still have problems getting updates for the status of the interfaces, etc...then, there is another problem, probably with "consistency" of yur objects database, let us know and let see if we can improve it, ok?

Hope this helps,
