RE: ONCONFIG for 9.40 offered for comment

what about.... 1. setting OPTCOMPIND to 2 instead of 0 2. set TBLSPACE_STATS to 0 3. may need to increase DS_TOTAL_MEMORY, if you are using PDQ 4. fyi, LTXHWM & LTXEHWM need not be set if DYNAMIC_LOGS is set in the ONCONFIG -----Original Message----- From: owner-informix-list@iiug.org [mailto:owner-informix-list@iiug.org]On Behalf Of Neil Truby Sent: Wednesday, June 16, 2004 12:01 AM To: informix-list@iiug.org Subject: ONCONFIG for 9.40 offered for comment 9.40 FC3W2 on HP-UX 11.11 The server has 6 cpus and 6G of RAM. 3 other, small, IDS 9.40 instances run on the server, and one small 7.31. kaio is enabled. Just put 9.40 live, and it's running about 5-10% more slowly on some key processes. This reflects what happened in testing. In particular we seem to be having fun and games with the new BTscanners. I thought I'd post the ONCONFIG for comment - any and all gratefully received! thanks Neil P.S. We know we'll have to increase SHMVIRTSIZE, as full-throttle BT scanning breaks out more segments ... #************************************************************************** # # INFORMIX SOFTWARE, INC. # # Title: Onconfig for instance 1 # Description: INFORMIX-OnLine Configuration Parameters # #************************************************************************** # Root Dbspace Configuration ROOTNAME rootdbs # Root dbspace nameROOTPATH /opt/informixV7.13/dbspaces1/rootdbs # Note from Neil - before my time!!!!!
