Don't worry. No-one got killed, even though though there have been a few punching-ins.
Fatal error
Yesterday I came across the fatal error that would prevent me to access databases from the console. I've started calling tech support and figured out that input stream pops up with invisible character(s) that need to be cleared after an input of Data Base ID before pressing an Enter key.
It was invisible bug -- a Ghost In The Machine.

None except @fuzztone got that what Ghost In The Machine is, but okay to go on. No worries. |
Not trying to explain anything to you, I thought it humorous that you posted a thread about a DB error, that's all! I too worked in IT for many decades, now retired. I applaud you for 30 yrs, I know how difficult it can be. First thing I programmed was on a PDP-11 by hand in binary. Long time ago. Regards, barts |
@barts Cognos DB platform the window where you punch-in DB ID was indeed corrupt as if you would never see anything there even with PCR microscope. normally it shouldn’t be any issue punching in any DB ID, but in this case there was a ghost character in the window preventing accessing DB due to unwanted and invisible character(s). Are you trying to explain what visible what not to IT veteran with 30 years behind or what son? First you really need to know what is Ghost In The Machine before we even continue |
Usually if the input is padded with blanks, no issues. Null characters might be, but there are more than just blanks and null characters that might not be visible so blanking them out blindly worked even having the fact that there's somewhere in the input stream one or few invisible ones are "hiding".
