I am seeing the following in the ONCONFIG. VPCLASS cpu,num=12,noage,autotune=1 VPCLASS aio,num=2,noage,autotune=1 I don't see autotune documented. Is this not the same as: AUTO_AIOVPS 1 Don't see any AUTO_CPUVPS Thanks Kernoal

Hi, IBM site is down so had to use google cache but it is documented: https://webcache.googleusercontent.com/search?q=cache:ZvxP4BaiCbUJ:https://www.i bm.com/support/knowledgecenter/en/SSGU8G_12.1.0/com.ibm.adref.doc/ids_adr_0189.h tm+&cd=1&hl=en&ct=clnk&gl=uk In fact it is documented for VPCLASS cpu: https://webcache.googleusercontent.com/search?q=cache:eESbIg5947oJ:https://www.i bm.com/support/knowledgecenter/en/SSGU8G_12.1.0/com.ibm.admin.doc/ids_admin_1424 .htm+&cd=2&hl=en&ct=clnk&gl=uk Regards, David. > On 20 February 2018 at 19:58 KERNOAL STEPHENS <informixdba@gmail.com> wrote: > > > I am seeing the following in the ONCONFIG. > > VPCLASS cpu,num=12,noage,autotune=1 > VPCLASS aio,num=2,noage,autotune=1 > > I don't see autotune documented. > > Is this not the same as: > AUTO_AIOVPS 1 > > Don't see any AUTO_CPUVPS > > Thanks > Kernoal > > > ******************************************************************************* > Forum Note: Use "Reply" to post a response in the discussion forum. >

Ended up setting both in the onconfig: AUTO_AIOVPS 1 VPCLASS aio,num=2,noage,autotune=1 Got the following information on startup from oninit -vy not the online.log Reading configuration file '/ifmx/ids/etc/onconfig'...Warning: VPCLASS setting for aio class overrides AUTO_AIOVPS. (AUTO_AIOVPS) My guess it would be better to have AUTO_AIOVPS to allow for a dynamic change later if needed. Thanks
