Re: ITM 6.2.3 FP2 is FTO totally broken?

Much of the redundancy scenarios would be cases where server running the 
hub TEMS/primary role is either not functional [Building collapse 
perchance] or where there is a network outage that isolates the system 
running TEMS/primary role.  In that case, having a WPA on that system 
which might connect to another hub TEMS isn't much value. It would be far 
more redundant to have a WPA that is on each TEMS hub and remote and 
configured to take the workload that the TEMS would normally handle.

Lots of people only test the things that area easy to test... like 
stopping the hub TEMS/primary. But in real life, things are usually more 
pervasive.

John,

Most folks (at least the ones I have talked to) configure their WPA's for 
failover using both the primary and standby TEMS.  While you are correct, 
the WPA can't log into the backup when its the backup, it can when the 
primary fails and the backup becomes the acting HUB.  That is (hopefully) 
the only case in which your WPA's couldn't contact the primary?during a 
failover.

Regards,

I am really confused. 

Warehouse Proxy Agents are agents like any other. They are made part of a 
system generated MSL that represents all WPAs. There are a few situations 
which run at the WPAs - reporting error conditions etc. 

Also, in my experience - each WPA should be configured to a single hub 
TEMS... not to both hub TEMS. The reason is that the hub TEMS with the 
backup role will *not* accept any agent connections. [Actually it does 
accept a connection and then immediately sends a "go find another TEMS and 
disconnects". 

1) But I cant get WHP MSL's to sync and no situations subscribed to MSL's. 

==> What is meant by sync'ing the WHP MSL's. ANd what does "no situations 
subscribed to MSLs" mean - a sentence fragement it looks like. 

2) WHP situations that have agents as distribution target seems to sync 
just fine though. 
==> WHP situations should be distributed only to WPAs, of course. 

In any case... WPAs connecting to a hub TEMS should only be configured to 
that one hub TEMS. I suggest testing that setup out.

Hi all. 
  
Just installed two HTEMS'es with FTO on RHEL6 with 6.2.3 FP02 in our test 
env. 
Both servers are identical with TEMS/TEPS on Derby/WHP all at 6.2.3 FP02. 
Both TEPS connect locally to each TEMS 
Both WHP agents has the primary HTEMS as its primary connection and the 
secondary HTEMS as secondary, all by the book if you reda the manual. 
  
The FTO "seems" to be working fine switching back and forth when I 
stop/start the TEMS'esr 
But I cant get WHP MSL's to sync and no situations subscribed to MSL's. 
WHP situations that have agents as distribution target seems to sync just 
fine though. 
  
Also tried creating a sit when the secondary was acting HUB, but it never 
got synced to the other TEMS. 
  
Anyone or is it just me? 
  
/Gus
