Upgrade from 9.4 to 11.10

Current environment: HP rp5405 (4 PA-8700 650MHz CPUs), 8GB ram, 4 drives (2 mirrored for O/S, 2 mirrored for my Informix DB so only 1 spindle to work with) HPUX 11.11 IDS 9.4FC3 We are getting an upgrade to 11.10FC2W4 (we don't get to choose versions) and the onconfig parameters have changed some and I want to ensure we are both using good parameter values overall and good parameter values for the hardware we have (primarily are we using memory to our fullest advantage). This server's only function is the Informix DB. It only has 1 instance with 1 production DB and 4 copies of that DB for development and testing usage. We only use ontape for our backups (to a remote file system mount). All dbspaces are raw and we use symbolic links to reference the actual devices. I have listed our existing 9.4 onconfig as well as our proposed 11.10 onconfig. We are primarily OLTP during day and then run many DSS style queries/mass updates via cron nightly. Our focus is to ensure the OLTP performs well, if the DSS suffers, that is OK, we aren't running into any issues with tasks not completing before next business day. Any thoughts and/or recommendations would be greatly appreciated. I will gladly provide any additional info that you may want/need (if I know how to get it, I am not truly an IDS DBA or HPUX SA, but I have managed to keep it running so far). ------------------------------------ 9.4 current onconfig: # Root Dbspace Configuration ROOTNAME rootdbs # Root dbspace name ROOTPATH /db/links/rootdbs # Path for device containing rootdbspace ROOTOFFSET 0 # Offset of root dbspace into device (Kbytes) ROOTSIZE 384000 # Size of root dbspace (Kbytes) # Disk Mirroring Configuration Parameters MIRROR 0 # Mirroring flag (Yes = 1, No = 0) MIRRORPATH # Path for device containing mirroredroot MIRROROFFSET 0 # Offset into mirrored device (Kbytes) # Physical Log Configuration PHYSDBS physdbs # Location (dbspace) of physical log PHYSFILE 60000 # Physical log file size (Kbytes) # Logical Log Configuration LOGFILES 85 # Number of logical log files LOGSIZE 12000 # Logical log size (Kbytes) LOG_BACKUP_MODE CONT # Diagnostics MSGPATH /i9.4/informix/online.log # System message log file path CONSOLE /dev/console # System console message path ALARMPROGRAM /db/scripts/no_log.sh # Alarm program path # System Archive Tape Device #TAPEDEV /dev/rmt/2m # Tape device path TAPEDEV /remote/recovery/informix/level0 # Tape device path TAPEBLK 16 # Tape block size (Kbytes) TAPESIZE 30000000 # Maximum amount of data to put on tape (Kbytes) # Log Archive Tape Device #LTAPEDEV /dev/rmt/2m # Log tape device path LTAPEDEV /ltape1/informix/log1 # Log tape device path LTAPEBLK 16 # Log tape block size (Kbytes) LTAPESIZE 4500000 # Max amount of data to put on log tape (Kbytes) # Optical STAGEBLOB # INFORMIX-OnLine/Optical staging area # System Configuration SERVERNUM 0 # Unique id corresponding to a OnLineinstance DBSERVERNAME courtshm # Name of default database server DBSERVERALIASES # List of alternate dbservernames DEADLOCK_TIMEOUT 60 # Max time to wait of lock indistributed env.
