Coolsights2000 Posted August 23, 2004 Posted August 23, 2004 Hi All!I saw Qchain.exe was included at the end of svcpack.inf over in the tutorials for SP1http://unattended.msfn.org/xp/installhotfixes_old.htmDo we still need it for SP2Mac!
big_gie Posted August 23, 2004 Posted August 23, 2004 QChain wasn't intended to be used with XP since it should include QChain feature...People are still using it though... And I don't know about SP2.
GreenMachine Posted August 23, 2004 Posted August 23, 2004 QCHAIN functionality may be required of two hotfixes both update the same file. QCHAIN functionality is included in Type I Hotfixes, but (I believe) NOT in Type II Hotfixes. It's small, and easy to add to SVCPACK.INF. I will continue to use it until I see a good reason not to. My installations need it with XP SP1 + Hotfixes.
Coolsights2000 Posted August 23, 2004 Author Posted August 23, 2004 Ok thanks!I'll leave it there till I see something different posted...Mac!
Coolsights2000 Posted August 23, 2004 Author Posted August 23, 2004 QChain wasn't intended to be used with XP since it should include QChain feature...People are still using it though... And I don't know about SP2.HUM!This article describes how to install multiple Windows product updates (for example, critical updates, security patches, or hotfixes) that use Hotfix.exe (Microsoft Windows NT 4.0) or Update.exe (Microsoft Windows 2000, Microsoft Windows XP, or Microsoft Windows Server 2003) with only one restart. This article is intended for administrators and IT professionals. You can install Windows product updates that use Hotfix.exe or Update.exe either alone or in combination with Windows (with or without a service pack).http://support.microsoft.com/default.aspx?...&NoWebContent=1Here was the kicker I found this in a link from the page abovehttp://www.microsoft.com/windowsxp/downloa...1/hfdeploy.mspxUsing Qchain.exeWindows XP SP1 and all post-SP1 hotfixes have Qchain.exe functionality built in. You can install SP1, and then install any number of post-SP1 hotfixes without having to restart the computer in between. For more information about how the Qchain.exe tool works, see article Q296861, "Use QChain.exe to Install Multiple Hotfixes with Only One Reboot," in the Microsoft Knowledge Base.So it looks like We don't need it anymore..Mac!
big_gie Posted August 23, 2004 Posted August 23, 2004 @Coolsights2000Yes. I posted that link some time ago, but since using qchain doesn't seems to have negative effects, people are still using it. As GreenMachine said, if it doesn't broke something, there is no reason to take it out...I'm not sure its really usefull though.
Aaron Posted August 23, 2004 Posted August 23, 2004 qchain is most likely not needed any more. You will still have to be careful with type 2 hotfixes as they don't use update.exe and qchain.exe cannot help in this case. (i.e. 2 IE cumulative updates being installed causing problems)
GreenMachine Posted August 23, 2004 Posted August 23, 2004 I hate to insist, and even more contradict Aaron, but my tests showed that it WAS needed as recently as a few months ago. As my memory serves me (for all that is worth ...) it was for Type II hotfixes.The way QCHAIN works is it checks the registry key that contains the list of files that are to be overwritten upon next reboot, and the name of the file that will be used to overwrite. The new files are usually files named something like SET00n.TMP that replace .DLL or .SYS files. The registry key contains the name of the original file. QCHAIN checks the version numbers and removes any entris that subsequently replace a newer version with an older version.That said, if you do not have two hotfixes that replace the same file, you certainly will not need it. If you do have two hotfixes that replace the same file, and they are installed in the correct order, you still will not need it. However, in the XPCREATE list of hotfixes used recently (Pre-SP2), there were two hotfixes that replaced the same file, and the "later" hotfix (i.e. higher numbered hotfix) replaced a file with a lower version number than the earlier hotfix. QCHAIN resolved this issue. That was the only instance I can remember where QCHAIN helped. But, one was enough for me.
Aaron Posted August 23, 2004 Posted August 23, 2004 Oh i see. I thought qchain didn't do anything for the type 2 hotfixes because several people who said they had problems getting the IE/OE Cumulative update to install was because they had older versions being installed as well.
GreenMachine Posted August 23, 2004 Posted August 23, 2004 Just sharing my experiences ... I did look into the registry when I ran them with and without QCHAIN, and that is what I surmised. And I do agree, we will probably not need it any more, but since I use the same procedure for WIN2K/WINXP/2K3SERVER, I leave it in there.
Denney Posted August 23, 2004 Posted August 23, 2004 To all, as of SP2, qchain is NOT needed if you use the /integrate option when adding hotfixes to your installation.By using /integrate, it'll check to make sure it's only updating files that need updating and not just blindly overwrite them.I'm glad to see Microsoft have finally added this feature to update.exe.
RyanVM Posted August 23, 2004 Posted August 23, 2004 Does the integrate switch imply that hotfixes can be integrated into install CDs now or am I misreading that? I know the /integrate switch worked for slipstreaming SP2 in one step instead of two.
Denney Posted August 24, 2004 Posted August 24, 2004 @RyanVM: It sure does. The /integrate switch works the same way as the /integrate switch for SP2 (almost).Running a hotfix with /integrate and pointing it to where you're install CD is, it will automatically add/replace the files to the CD, create an SVCPACK directory, copy the .cat files there and make an SVCPACK.INF file.
Coolsights2000 Posted August 24, 2004 Author Posted August 24, 2004 from what I can tell the two packages DOTNETFX and kb8321240 do not allow the /integrate switch cause neither one of them meet this page qualificationhttp://support.microsoft.com/default.aspx?kbid=262841neither of them are a hotfix or a update..they both install something new.......Dotnetfx goes with these two pages http://support.microsoft.com/default.aspx?kbid=197147http://msdn.microsoft.com/library/default....ine_options.aspand the kb8321240 goes with these pageshttp://support.microsoft.com/default.aspx?...kb;en-us;227091http://msdn.microsoft.com/library/default....ine_options.aspboth of them use the windows installer and the switches for the windows installerthese are the only two that I'm install on too SP2.. I'm not going to load the viewer one cause it conflicts with office 2000,, the MS support help fix says to uninstall the viewer...
Denney Posted August 24, 2004 Posted August 24, 2004 If you installing something NEW like those updates, QCHAIN won't help much. QCHAIN is only needed when a hotfix is going to overwrite an older file.With SP2, all new hotfixes will contain the /integrate option.
