RE: ontape -a "this tape contains no log data"

Posted By: alberto rodriguez

In Response To: Re: ontape -a "this tape contains no log data" (Art Kagel)

Hi mr Kagel,
In truth the file is well, it has correct permissions and is empty
before the ontape -a. There was a process that it blocked to ontape -a, only was to kill several sessions (onmode - z) of informix
user and the problem was solved.
Thanks for your help
