RE: HDR problem with Windows

Ben, Don't you see something strange on one of machines, like an abrupt increase of CPU usage? Are there some strange messages in Windows system and application logs (in 'Event viewer')? Is Firewall started on Windows? Is IPV6 started? For safety, try to configure al least two CPU VP's on each machine and move NETTYPE to NET VP -Alexey > -----Original Message----- > From: informix-list-bounces@iiug.org [mailto:informix-list-bounces@iiug.org] > On Behalf Of Ben Thompson > Sent: Thursday, June 29, 2006 12:15 PM > To: informix-list@iiug.org > Subject: Re: HDR problem with Windows > > Guy Bowerman wrote: > > Some minor comments: > > > ROOTPATH D:\\IFMXDATA\\ol_server1\\rootdbs_dat.000 > > > > You've moved the root dbspace to D:\\IFMXDATA\\ol_server1 on ol_server2 as > > well right? > > Yes, the directory name is the same on both servers.

The cause of the problem only became apparent when I restored a tape to the secondary using "ontape -r": we could only connect to it from the machine itself. We had seen these symptoms on UNIX machines before when Informix binds to the local loopback device. The system has two network cards. On a UNIX system Informix binds to the card by looking up the server name in onconfig, using sqlhosts to map this to a name or IP, if a name it is looked up in hosts or DNS and that interface is used. I had assumed Informix for Windows works the same but it doesn't. It seems to use the system binding order and this was the wrong way around on the secondary. I changed this and everything worked. The error message that was being reported on the primary was sending us in completely the wrong direction! Many thanks to Alexey and Guy for helping me out. Ben.
