Hi david, it morning again here,' Yeah we moved to a dedicated file server for the desktops, however, we will now be moving back to the file cluster for DR replication.=20 I would 100% recommend putting the oracle forms on each MF box if you have the space. Disk reads are also a lot faster the network i/o You'll prob get more users on the box too as a result of less network traffic etc etc John -----Original Message----- From: Lee, David (CITY TREASURY) [mailto:David.Lee@xxxxxxxxxxxxxxx]=20 Sent: Thursday, January 16, 2003 1:01 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Re: Citrix and MSCS failover problem Thanks John. Did you implement the dedicated forms server because you also have a large number of PC clients? I'm now starting to think in terms of installing a local copy of the Oracle forms folder onto each Citrix server; we don't have PCs accessing the app, so this wouldn't be too much trouble to maintain. -----Original Message----- From: Rowlandson, John [mailto:John.Rowlandson@xxxxxxxxxxxxx] Sent: 15 January 2003 11:36 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Citrix and MSCS failover problem sp3 on both sp3 on the cluster helped but did not not solve the problem we ran up a standalone oracle forms file server for our largest office = =3D (900 users) oracle is our biggest headache internally if a notebook user uses oracle in the office they get it via MF due to = =3D wireless drop outs whilst moving from floor to floor in the lift, MF =3D lets them reconnect to their session. where as across the network, =3D oracle wont cope withlosing and refinding the forms file share. =3D seeingour forms and orant is 5 gb we cant load it locally on all pcs we wrote an app that reads the IP of the pc and looks thru a ini file of =3D subnets and codes ie 172.22.18. c:\program files\citrix\pn.exe /app sydp.ica 172.22.100+ q:\keystone ifrun60.exe "blah blah" our client is 6i developer, ifrun60.exe is version 6.0.8.16 John -----Original Message----- From: Lee, David (CITY TREASURY) [mailto:David.Lee@xxxxxxxxxxxxxxx] Sent: Wednesday, 15 January 2003 10:07 PM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Re: Citrix and MSCS failover problem After proper failover testing last night, I've now verified that the =3D file share is moving over correctly, so it seems that the Oracle app is =3D indeed sensitive to the brief disconnect. =3D20 John, what version of the Oracle client are you running? Also, are you running Win2k SP3 on the cluster, on the Citrix boxes, or both? We're running SP3 on the cluster, but have stayed with SP2 on the Citrix =3D boxes.

The drive will show as being disconnected, until it's accessed - =3D3D depending on settings. There are some settings for office apps (eg excel) with respect to =3D3D problems occurring with things like macros post failover. It could just be that some apps are just a bit sensitive to failover / drives going offline / disconnecting - even if only for brief periods.
