Hi Tom, EBCDIC isn't strictly mandatory, but it is the lingua franca of mainframes, so for most applications not running EBCDIC would result in constant translation between EBCDIC and ASCII, which can become a performance issue. The platform does support ASCII and Unicode, but in most cases y

Hi Tom, No, I haven't tried at this point. I thought it would be a good first step to find out whether anyone else had already tried, in order to avoid reinventing any wheels. z/OS UNIX does have certification as a UNIX system, but there are some quirks. The most common sources of problems w

Folks, At Linuxworld Expo/SF, I got a chance to talk a bit with one Andrew Schmidt of IBM about the possibility of porting PostgreSQL to z/OS. Here's what he asked about. Any z/OS developers in the house who can address it? Cheers, D - Forwarded message from Andrew Schmidt <[EMAIL PROTECTE
