Title: Redundancy for EMPS ¿?
Post by: aponterules on January 18, 2010, 05:03:25 PM

Hi

I have the following scenario
3 servers with gvp (VCS) software installed (no EMPS) and 1 server with gvp (VCS) software installed and EMPS installed for all 4 gvps, so the question is What would happen if the server with gvp and EMPS is shutted down? I mean, customer is saying that in case this server breaks down the other 3 gvps would not work any more until the server running EMPS comes back

And What can I do in order to create a backup plan, I was thinking to create a complete Windows image so in case this server breaks down we can install the windows image in another server

If EMPS goes down you will lose configuration of GVP but IPCS/VCS will still work as long as dispatcher and other components like that are up and running

But Dispatcher and the other components you refer are installed on each server?

Now, In case I need to reinstall an EMPS with the same parameters or configurations, which files or folders do I need to backup from actual server so in case something wrong happens with the actual server I can restore those files or folders in a new "empty" EMPS in order to simulate that nothing happened

The LDAP database should be enough

And how can I clone the ldap database

Just copy the folder ../openladp ? Or do I need to stop openladp service and execute a command or run the openldapbackup_utility.bat file in order to create a ldif file?

Thanks

I can suggest to use sun one directory server for you. At last week i done gvp 7.6 installation from scratch :)
i think the best way is to migrate to one from previous version - using built-in backup/restore function.
As for EMPS - every time when you starting gvp (watchdog service starts at the first stage), they tries to ask emps about config. If it was success, they stores config into local gvp.ini file. If the remote emps wasn't reachable - local gvp.ini is used. So, if your emps is in down - your services will forks fine. And what is more - you can add special parameter to gvp.ini in watchdog section to force don't read config from emps and use a local gvp.ini - as you wish. So, emps is not "mission critical" service, e.g. i haven't redundancy pair for it.

Can you tell me how to configure the local gvp.ini file to force don´t read config from emps??

This configuration works only when the EMPS fail?

Although I change this configuration in the gvp.ini file I need a dispenser up??
