Oracle Applications Release 11i with Oracle Database 10g Release 2 (10.2.0)

Question

Hi,
I am upgrading our Oracle EBS 11i database to Oracle 10g R2 as per note:362203.1.
In section After the Database Upgrade  --> 5. Implement and run AutoConfig we need to refer to Note:165195.1.(Section 8: Migrating to AutoConfig on the Database Tier).
Since I dont have the DB enviornement file, I created one by copying the envioroment file from Oracle 9i Home and replaced 9.2.0 with 10.2.0. I also created Apache directory under Oracle 10g Home and copied perl directory from Oracle 9i Home/Apache to Oracle 10g Home/Apache. This way I got the DB enviornement file for Oracle 10g Home.
Then I used the following command to create the DB Context File:
perl adbldxml.pl tier=db appsuser=apps
Then executed autoconfig using:
adconfig.cmd contextfile=<Full path to the CONTEXT>
Is this the way I should do? Its working ok but I am not sure if my method is ok.
Plz suggest if some other method is there.
Thanks.

This is a way I used to do it too. I am not sure whether it is the official way, but it works nevertheless.
Do make sure you run autoconfig afterwards, which will create a new environment file for you. Then stop listener and database, source the new environment file and restart listener and database.
I found some other procedure in order for you to recreate the environment file:
1. On the application tier, Execute $AD_TOP/bin/admkappsutil.pl to generate appsutil.zip for the database tier.
2. Copy this appsutil.zip to the database tier and unzip it into the ORACLE_HOME
3. Set the following environment variables:
ORACLE_HOME =<10g ORACLE_HOME>
LD_LIBRARY_PATH = <10g ORACLE_HOME/lib, 10g ORACLE_HOME/ctx/lib>
ORACLE_SID = instance name running on this database node.
PATH= $PATH:$ORACLE_HOME/bin;
TNS_ADMIN = $ORACLE_HOME/network/admin/<context_name> 4. Edit the $ORACLE_HOME/network/admin/tnsnames.ora file. Change the aliases for SID=<new RAC instance name>
5. Modify the listener.ora. Change the instance name and Oracle Home to match environment
6. Start the listener.
7. From the 10g ORACLE_HOME/appsutil/bin directory, create an instance-specific XML context file by executing the command:
adbldxml.pl tier=db appsuser=<APPSuser> appspasswd=<APPSpwd>8. De-register the current configuration using the command:
perl $ORACLE_HOME/appsutil/bin/adgentns.pl appspass=apps contextfile=$CONTEXT_FILE -removeserver9. Rename $ORACLE_HOME/dbs/init<rac instance>.ora , to a new name (i.e. init<rac instance>.ora.old in order to allow AutoConfig to regenerate the file using the RAC specific parameters.
10. From the 10g ORACLE_HOME/appsutil/bin directory, execute AutoConfig on the database tier by running the adconfig.pl script.
Now you should have the officially created environment file.
HTH.
