This function returns the IP address of the client.
The IP address. The owa_util.ip_address data type is a PL/SQL table where the first four elements contain the four numbers of the IP address. For example, if the IP address is 220.127.116.11 and the variable ipaddr is of the owa_util.ip_address data type, the variable would contain the following values:
This function returns the password that the user used to log in.
For security reasons, this function returns a true value only when custom authentication is used. If you call this function when you are not using custom authentication, the function returns an undefined value. Thus, the database passwords are not exposed.
This function returns the username that the user used to log in.
This procedure, called in the initialization portion of the OWA_CUSTOM package, sets the authorization scheme for the PL/SQL Gateway. This implements your authorize function, which authorizes the user before his requested procedure is run. The placement of the authorize function depends on the scheme you select.
The authorization scheme. It is one of the following schemes for SET_AUTHORIZATION:
OWA_SEC.NO_CHECK - Specifies that the PL/SQL application is not to do any custom authentication. This is the default.
OWA_SEC.GLOBAL - Defines an authorize function that is called for all users and all procedures. This is the OWA_CUSTOM.AUTHORIZE Function in the "sys" schema.
OWA_SEC.PER_PACKAGE - Define an authorize function that is called when procedures in a package or anonymous procedures are called. If the procedures are in a package, the package.AUTHORIZE function in the user's schema is called to authorize the user. If the procedures are not in a package, then the anonymous authorize function in the user's schema is called.
OWA_SEC.CUSTOM - Implements different authorize functions for each user. The function OWA_CUSTOM.AUTHORIZE Function in the user's schema is called to authorize the user. If the user's schema does not contain an OWA_CUSTOM.AUTHORIZE Function, the PL/SQL Gateway looks for it in the "sys" schema.
The custom authorize function has the following signature:
If the function returns TRUE, authentication succeeded. If it returns FALSE, authentication failed. If the authorize function is not defined, the Gateway returns an error and fails.
This procedure sets the realm of the page that is returned to the user. The user enters a username and login that already exist in the realm.
