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.

Are you sure you're OK? Have you taken too much and need professional attention?

Let me know. Otherwise probably it's definitely IQ deficiency that isn't curable.

 

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".

 

@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
