example of code:

REQID STIND OF 8 DIGIT REQUEST NUMBERS, IE . 12345678

GTC1=LITERAL

FILEIN = /main/submain/submain/DESTINATION/REQID:".GTC1"

THE FILE DOESNT EXIST TO START

When i run this program as a standalone is works perfectly.

When i run this program as a PHANTOM it takes both else clauses

OPENSEQ FILEIN TO OUT.FILE ELSE

CREATE OUT.FILE ELSE

MSG = "CANNOT CREATE ":OUT.FILE

CRT MSG

STOP

END

END

RUNNING ON REDHAT LINUX 8.10 UNIVERSE REL 11.4.1.6020

PERMISSIONS HAVE BEEN CHECKED

USER:GROUP ARE CORRECT

any help would be greatly appreciated

Theodore,

I'm assuming you don't use GCI and have not changed PATH or the UniVerse uvsh to be script wrappers....

Put a pause at the start of the PHANTOM to give you time to identify the PID of the UV process. Once identified then from a separate UNIX command shell as Administrator (sudo is also fine) run strace -f -p PID 1>strace_PID.out 2>strace_PID.err - substituting the UniVerse PHANTOM PID throughout. This should be timed to be running BEFORE the PHANTOM wakes up and does any work.


Hopefully the ...err file will have detailed tracing - I'm laying odds on permissions or an environment variable.

ADDED: It would also be useful to put a check on STATUS() immediately after the file operations that fail - even a failure to fail should not be assumed a success.

Regards

JJ

Theodore,

Another option is to add ON ERROR clause to the OPENSEQ statement to get more information about what might be blocking the open.
