A program that you write and that Oracle OLAP checks for by name when an AW ATTACH read/write statement executes. Depending on the value returned by the program, Oracle OLAP executes the code within the program after attaching the analytic workspace.


Oracle OLAP checks for other programs when a user attaches a workspace. See "Startup Programs" for more information.



TRUE when Oracle OLAP has successfully set up and attached the analytic workspace; or FALSE when it has not or when the permit_write program has thrown an exception


You are encouraged to use the normal return values rather than relying on exceptions to create a return value of FALSE.


To define a program with the name PERMIT_WRITE use the syntax shown in DEFINE PROGRAM. Code the actual program as a user-defined function with the following argument.

PERMIT_WRITE (password)


See AW ATTACH for an explanation of password.


When a user specifies a password when attaching the analytic workspace, then the password is passed as an argument to the program for processing.


Creating a permit_write program

A program with the name of permit_write does not exist within an analytic workspace unless you define and write one. You write a permit_write as a user-defined functions that returns a BOOLEAN value. You can use the return value to indicate to Oracle OLAP whether or not the user has the right to attach the workspace.

Depending on the statements in the permit_write program, the user is granted or denied access to specific objects or sets of object values. Within permit_write program, you can specify PERMIT commands that grant or restrict access to individual workspace objects.


All of the objects referred to in a given permit_write must exist in the same analytic workspace.


For examples of how attachment programs, see Example 8-14, "Startup Programs".
