Before you can define programs in UNIX files to program control, you need READ access to the BPX.FILEATTR.PROGCTL resource in the FACILITY class. Then use the extattr command with the +p option to set the program control extended attribute.

extattr +p /user/sbin/proga  

Tip: The attribute is turned off if there is any activity that can change the contents of the file. If this happens, a system programmer with the appropriate privilege will have to verify that the file is still correct. Then the programmer will have to issue the extattr command to set the program control attribute back on. To find out if the program control extended attribute has been set, use the ls -E command.
