How to enable KAIO on SCO ODS 5.0.5?

Hi everybody. I have a lot of problem when i'm tried to bring up KAIO on IDS 7.30 UC2 under SCO OpenServer 5.0.5. Did anybody use KAIO under this plataform? Could you tell me how to enable KAIO under this plataform? In this point, I've done that: first, I make the raw devices. They had owner and group right, they had access permissions right, too. Those are may raw devices: crw-rw---- 1 informix informix 99, 4 Mar 20 15:55 /dev/rdsk/vdisk4 crw-rw---- 1 informix informix 99, 5 Mar 16 10:51 /dev/rdsk/vdisk5 They was making with SCO Virtual Disk Manager. Second, I enabled the SCO suds drivers. I edit the file /etc/conf/sdevice.d/suds and check it so : # cat /etc/conf/sdevice.d/suds suds Y 1 0 0 0 0 0 0 0 Third, I enabled the SCO AIO Drivers. I used mkdev aio, chanced some kernel parameter, relinked the kerner. After I check it so: # aioinfo total aio_info slots 16 active aio_info slots 0 number of memory locks 0 total locked memory 0 total ureq structures 200 active ureq structures 0 free ureq structures 200 cumulative ureq usage 0 maximum ureq usage 0 total aio buf structures 200 free aio buf structures 200 In last, I set envioroment variable KAIOON=1 and I tried to bring up the instance, I always got same error: errno = 14. 11:16:19 Event alarms enabled.

After this patch you must found /dev/async file. And I don't advice to you using 7.30.UC2 with KAIO, better use 7.31.UC5 - this version is MUCH stable with KAIO. -- ------------------------------------------------- With best regards, Yuri Dovgart SAP R/3, Informix technical consultant, Informix Certified Professional, Senior System Consultant System Architecture and High Availability Systems, 'Telecominvest' company Email y_dovgart@tci.ukrtel.net ICQ 39284285 > > 11:16:19 Event alarms enabled.
