I want the user to view all other schema

Question

hi all
i have a project with 5 modules(GL, AP, AR, OM, PO) and each module has its own schema (tables,pkgs,views,.................)
and i want to create a new user(test) that don't have any objects , i create it only to connect on forms by it
and i want that user to access all other users objects
NOTE:- i create a public synonym(inside each schema) to each table in each schema to access it by this synonym when i connect by user (test)
but when i try to select from these synonyms it give me : insufficient privileges
what can i do?
thanks

Answer 1

There are few ways of doing this
1) Create a LOGON trigger for the user.
In the logon trigger you will change the user to say GL, the use will be no need to qualify the objects with GL.object_name by default all references to OBJECT_NAME will be replaced by gl.object_name. the connected user wills till have his own priveleges which mean he still needs to have grants.Read more on LOGONG triggers
2) Create Private Synonyms and and give grants to Individual users.
3) My Preferred Method: Create a Role with all the required privelieges. Grant Role to users. This will save time everytime you create a new user.(This menthoed can be clubbed with the first method of creating logon trigger)
Please do not create public synonyms.You WILL run into issues sooner or later when you start writing you own customized code.
