Re: cannot start with 4 AIO virtual processor

On Windows platforms IDS is KAIO only, hence in most cases there is no need for more than 1 AIO VP. In IDS versions prior to 9.30.TC6 this limit was enforced and an error was generated when a higher value was used. With KAIO systems the AIO VP is still used for some tasks such as writing to log files, so there can be cases where more than one AIO VP is desirable, but usually 1 is fine. For this reason a bug was logged: 147844 ENGINE IS RESTRICTED TO COME UP WITH ONLY 1 AIO VP WHEN IT CAN BE BENEFICIAL TO HAVE MORE SET.... This bug is fixed in: 7.31.TD7 9.30.TC6 9.40.TC3 and higher. So in your case, set it to 1, it probably doesn't need to be any higher. Regards Guy Stefan Gabriel wrote: > informix can only be run with 1 aio vp under windows.
