Add CUSTOM TOP to R12 via Linux

Hi All

As you already know there is an option to add CUSTOM TOP to R12 via EBS Site Map -> AutoConfig.

Here the 2 ways to do it via Linux.
*** Pay attention : The Application need to be created before this action plans.

1. Stop APPL Tier
2. Login with application user to Linux
3. Edit $CONTEXT_FILE. Add the following line in the end of tops list:
<CUSTOM_TOP oa_var="s_customtop" oa_type="PROD_TOP" oa_enabled="FALSE">$APPL_TOP full path /custom/12.0.0</CUSTOM_TOP>

4. Create CUSTOM folder in $APPL_TOP: cd $APPL_TOP; mkdir CUSTOM folder
5. Create the following sub directories ( if need ):

./admin
./admin/sql
./admin/odf
./admin/template
./admin/driver
./forms
./forms/US
./html
./lib
./mds
./mesg
./patch
./sql
./bin
./help
./java
./log
./media
./out
./reports
./reports/US

6. Run AUTOCONFIG in APPL Tier
7. Re-login with application user to Linux and check that the CUSTOM TOP exists: echo $CUSTOM
8. Start APPL Tier

*** Some times this way not working properly after some custom changes and the custom line removed from $CONTEXT_FILE after AUTOCONFIG .So You can use the second action plan : 

1. Stop APPL Tier
2. Login with application user to Linux
3. Go to $AD_TOP/admin/template
4. Backup adxmlctx.tmp  : mv adxmlctx.tmp adxmlctx.tmp_bck
5. Add the following line in the end of tops list:
<CUSTOM_TOP oa_var="s_customtop" oa_type="PROD_TOP" oa_enabled="FALSE" default="%s_at4%%/%custom%/%12.0.0">%s_customtop%</CUSTOM_TOP>
6. Create CUSTOM folder in $APPL_TOP: cd $APPL_TOP; mkdir CUSTOM folder
7. Create the following sub directories ( if need ):

./admin
./admin/sql
./admin/odf
./admin/template
./admin/driver
./forms
./forms/US
./html
./lib
./mds
./mesg
./patch
./sql
./bin
./help
./java
./log
./media
./out
./reports
./reports/US

8. Run AUTOCONFIG in APPL Tier
9. Re-login with application user to Linux and check that the CUSTOM TOP exists: echo $CUSTOM
10. Start APPL Tier

Good Luck ...
