A permanent proxy user is an existing permanent user who is defined to Vantage. A GRANT CONNECT THROUGH request validates that a permanent proxy user who is specified in that request exists in Vantage. The anticipated use of permanent proxy users is for intranet-type middle tier applications that, for example, may display employee pay stubs or information about available vacation time.
Vantage assigns the name of the permanent proxy user as the creator of any objects created while the proxy connection is in effect.
You cannot have duplicate application and permanent proxy user names for the same trusted user. For example, consider the following GRANT CONNECT THROUGH requests submitted in the order indicated:
GRANT CONNECT THROUGH crm TO PERMANENT mary WITHOUT ROLE;
GRANT CONNECT THROUGH crm TO mary WITH ROLE hr_role;
The second request returns a duplicate proxy user name error because the permanent proxy user named mary already exists as granted through trusted user crm.
The roles that can be set for a permanent proxy user in a proxy connection are different depending on the WITH ROLES clause in the GRANT CONNECT THROUGH request, as listed in the following table.
| GRANT CONNECT THROUGH Request | Result |
|---|---|
| WITH ROLE |
|
| WITHOUT ROLE |
