Aldrin, As you have moved DB Tier, You can create appsutil.zip via admkappsutil.pl and bring it to database tier & make necessary changes to xml file regarding database host & run autoconfig but that won't be enough because of " Net Service Topology Model " . You have to deregister your database & reregister your database . Steps to do so are mentioned in 218089.1 Autoconfig FAQ Under Section Net Services Question 28 to 41 Check my post about How to change Hostname for Apps Instance at http://becomeappsdba.blogspot.com/2006/11/how-to-change-hostname-or-domainname.html also check metalink Note 338003.1 How to change the hostname and/or port of the Database Tier using AutoConfig Regards Atul Kumar http://teachMeOracle.com/forum <- Solution to all your Apps Issues.

How does one reflect the changes about the new host in the configuration files? Can the appsutil directory be copied over to new server and the <context>.xml file edited to reflect the new changes and then run adconfig? Currently using split config DB Tier -- Server A , App Tier B -- Server B {PLATFORM X) Moved DB Tier to new server --- Server A1 {PLATFORM Y} Thanks, Aldrin --------------------------------- This e-mail contains confidential information that is proprietary to EPCOR and its subsidiary companies in all respects.
