Interactive COBOL FailSafe Usage Readme 5.6x June-2026 Note that as of ICOBOL 5.60, the only valid protection method that is supported by ICPERMIT is MAC address protection. When started with a valid protection method, ICPERMIT creates a failsafe security file, system.fp. This failsafe security file can be used to start ICPERMIT for up to 3 weeks after the failsafe security file was last written. (While ICPERMIT is running, the filesafe security file is updated every 24 hours.) This insures that if the protection method fails, Interactive COBOL can still be used until a replacement license is received. From initial activation, the failsafe security file is good for 10 days. Within that timeframe, you should insure that your protection method/license has been replaced. The failsafe security file should NOT be modified in any fashion or else the file may NOT be usable when it is required. ****** Important Note ****** Just like you should regularly test your system backups, the failsafe security file should be routinely tested that it can be used to start an ICPERMIT to ensure some other program on the system is not interfering with its operation. **************************** Under Windows ------------- To use a failsafe security file either use the Services Panel and start the ICPERMIT service manually and add the -f switch or use ICSVCMGR to change the ICPERMIT service to add the -f switch. Under Linux ----------- To use a failsafe security file, edit the control script to add the failsafe switch (-f) when starting ICPERMIT. End of readme
