In Response To: Re: How to Setup IDS for all IPs (Art S. Kagel (Oninit LLC))

Hi,

cause of application is not able to handle database errors, a reconnect must be done.

I tried to use this line within the sqlhosts of my server:
ids_db onsoctcp * ids_db

and this one within my client

ids_db onsoctcp db01haip ids_db

Starting ids without ha ip and afterwards add haip with ifconfig.
So the connection via dbhaip is possible.

Thanks Sven

Clients still have to reconnect and the newly 'assigned' address has to
be listed in the sqlhosts file and has to be named either in the
INFORMIXSERVER or DBPATH environment variable or INFORMIXSERVER has to
be set to a group name that includes the assignable or floating
address. But this all misses the point. My point was, instead of
having the address failover, just use DBPATH or sqlhosts groups to
failover to the back up server's real address. Works just as well and
probably more reliably without waiting for heartbeat detection to switch
the addressing.
