IBM SC41-5420-04 manual Usage Notes, Length of operation-specificinformation, Allow operation

For operation identifiers 1 through 3, the operation-specific information contains the name of the directory or library on which the operation is to be performed. The directory or library name is formatted as an absolute path name.

For operation identifiers 4 through 8, the operation-specific information contains the name of the file on which the operation is to be performed. The file name is formatted as an absolute path name.

For operation identifier 9, the operation-specific information contains the iSeries Control Language (CL) command which is to be run at the user’s request.

Note: See “Usage Notes” for a summary of the operation-specific information that is required for each operation identifier.

Length of operation-specific information

INPUT; BINARY(4) Indicates the length (in bytes) of the operation-specific information, or 0 if no operation-specific information is provided.

Allow operation

OUTPUT; BINARY(4) Indicates whether the operation should be accepted or rejected. The valid values are as follows:

-1Never allow this operation identifier:

vThis operation identifier is to be unconditionally rejected for the remainder of the current session.

vThe exit program will not be called again for this operation identifier.

0Reject the operation

1Allow the operation

2Always allow this operation identifier.

v This operation identifier is to be allowed unconditionally for the remainder of the current session.

vThe exit program will not be called again with this operation identifier.

Usage Notes

For FTP, if the returned Allow operation output parameter is not valid, the FTP application will not allow the operation and the message “Data from exit program for exit point &1; is missing or not valid” will be issued to the job log.

For FTP, if any exception is encountered when calling the exit program, the FTP application will issue the message: Exception encountered for FTP exit program &1; in library &2; for exit point &3;

Two different exit points are provided for the FTP application. Exit point QIBM_QTMF_CLIENT_REQ is used to validate requests processed by the FTP client program. Exit point QIBM_QTMF_SERVER_REQ is used to validate requests processed by the FTP server program. If desired, the same exit program can be used to validate requests from both of these exit points.

Table 10 on page 88 summarizes the operation-specific information required for each operation identifier.
