Problem:

How can I recover from "Lock file lock error 13: Permission denied"?

Resolution:

If you get an "unauthorized use of runtime error", or an Loc 801, 802, 804, 806, or 807 error on a UNIX/Linux system, run the command:

rmucutil <serial number with use count > runtime details

where <serial number with use count > is the registration number with the use count as displayed by the runtime banner.

If this returns: "Lock file lock error 13: Permission denied", try deleting the lock file:


32-bit runtime: rm -rf /tmp/.RmCobolUC32

64-bit runtime: rm -rf /tmp/.RmCobolUC64


If you still get the error, try the following recommendations:

  • Clear the RM/COBOL shared memory
  • Check the license.vlt file permissions, and, ensure that all users/groups have read, and write, access.
  • Reboot the affected system.
