out of virtual shared memory - Informix
Hi Informix support,
I am not able to initialize Informix 7.31 running on NCR S 1400 h/w having
MP-RAS 3.02 operating system with 512 mb RAM.
Please find output of âoninit âvâ command , output of onstat âg seg and
onstat âg glo at the time of initialization, online.log, onconfig and
kernel parameters file.
Output of oninit âv
