How do you update sqlnet.ora thru autoconfig?

We are seeing frequent errror message in the database alert log:   Fatal NI connect error 12170.

Note #2112344.1 suggests adding this to the sqlnet.ora file on the client which is the EBS app server.

     SQLNET.OUTBOUND_CONNECT_TIMEOUT = 10

and then increasing it as needed.  We are on R12.2.5 of EBS. How do I update the autoconfig context file on the app server so that this line will be added to the sqlnet.ora file when I run autoconfig?

Thanks,

Nancy
