How to change the Web Port in EBS 12.2

As we all know,httpd.conf configuration is managed by FMW in R12.2, the method to change the webport is quite different in R12.2

Here are the steps to change Web Port in EBS 12.2
– Launch EM Console
http://<s_wls_admin_host>.<s_wls_admin_domain>:<s_wls_adminport>/em)

– Login as weblogic admin user (s_wls_admin_user)

– Select the webtier instance from the Web Tier drop down

– Select the Oracle HTTP server component and Advanced Configuration

– Choose httpd.conf for example

– Modify the Listen port value

– Save the changes

– Run Context File Synchronization $AD_TOP/bin/adSyncContext.pl
perl $AD_TOP/bin/adSyncContext.pl contextfile=$CONTEXT_FILE
– Manually update the $CONTEXT_FILE if old port values are still present
– Run autoconfig

– Check the value for s_login_page in the context file

– Also, context file should not have any references to old Listen port value

– Login to EBS and do some sanity testing
