RE: NT large memory configuration

I take it the instance comes up fine with fewer buffers etc. 300000 buffers = 1.2Gb on NT plus 131Mb SHMVIRTSIZE plue NT and anything else on it. What memory does the server have?

When I go about 300000 buffers and some 131MB of shared memory I get the usual complaints - 13:44:43 shmat: [EINVAL][22]: shared memory base address illegal 13:44:44 using 0xa000000, needs 0x14f0000 13:44:45 mt_shm_init: can't create resident segment I've attached the currently working onconfig file. I get an error like the above one when I bump up the # of buffers. I've tried setting SHMBASE to many different values without success - This is onconfig is from my development machine so yes I want LTAPEDEV to be NUL. #************************************************************************** # # INFORMIX SOFTWARE, INC. # # Title: onconfig.std # Description: Informix Dynamic Server Configuration Parameters # #************************************************************************** # Root Dbspace Configuration ROOTNAME rootdbs # Root dbspace name ROOTPATH d:\\IFMXDATA\\ol_gamera\\rootdbs_dat.000 # Path for device containing root dbspace ROOTOFFSET 0 # Offset of root dbspace into device (Kbytes) ROOTSIZE 262144 # Size of root dbspace (Kbytes)# Disk Mirroring Configuration Parameters MIRROR 1 # Mirroring flag (Yes = 1, No = 0) MIRRORPATH g:\\ifmxdata\\ol_gamera\\rootdbs_mir.000 # Path for device containing mirrored root MIRROROFFSET 0 # Offset into mirrored device (Kbytes)# Physical Log Configuration PHYSDBS physlog # Location (dbspace) of physical log PHYSFILE 81920 # Physical log file size (Kbytes)# Logical Log Configuration LOGFILES 44 # Number of logical log files LOGSIZE 8192 # Logical log size (Kbytes)LOG_BACKUP_MODE CONT # Logical log backup mode (MANUAL, CONT) # Diagnostics MSGPATH D:\\INFORMIX\\ol_gamera.log # System message log file path CONSOLE D:\\INFORMIX\\conol_gamera.log # System console message path ALARMPROGRAM D:\\INFORMIX\\etc\\log_full.bat # Alarm program path # System Diagnostic Script. # SYSALARMPROGRAM - Full path of the system diagnostic script (e.g. # d:\\informix\\etc\\evidence.bat.)
