iWay Server Profiles

Used by iWay server to customize the server environment
for different users and/or applications.



Can be applied on a
global
,
service
,
group
, or
user

level basis.


Used for application set up commands such as environmental
settings, search path, and DBMS connection information.


Run upon each connection to the iWay server.


Settings established by profiles are in effect for the duration of
the established connection.


The server processes all profiles found in the search order. If it
finds duplicate settings or commands, the last setting or
command processed will be active for the connection.
