Re: shared memory segment size

Ok - the resident part of the shared memory comprised the header, bufferpool, Logical log buffer, Physical log buffer and locks. 1 400 000 Kbyte for bufferpool - we have 700 000 buffers and 2k for each buffer 128 Kbyte for 2 phys buffers 192 Kbyte for 3 logbuffs 44 000 Kbyte for Locks - (we have 1 000 000 locks and i read in the manual that a lock hase 44 byte ) 1 444 320 Kbyte is the result The output from onstat -g seg is : 1 575 936 KByte What's about the rest ? Is 131 616 Kbyte for the Header ?????

Which IDS version? Under 10 a lock is larger. - Save a copy of your ONCONFIG file somewhere - Login as informix - point to the instance - Use onmonitor -> Parameters -> Shared Memory - Change the size of the parameters and see how the resident shared memory size changes in the bottom left of the screen.

Hey, great. I work so very seldom with onmonitor - so i don't know this. Thanks to Daivd ( and thanks to Nilesh Ozarkar for the Link !)

I work with 10.0.UC4
