getting IDS 2000 running on RH 6.2

I am currently trying to get IDS 2000 running on a RedHat 6.2 Linux box. I have taken the following steps - created an sqlhosts file in $INFORMIXDIR/etc/sqlhosts to have 1 connection for the localhost with shared memory IPC communication - created an onconfig file in $INFORMIXDIR/etc/ using onconfig.std as a template, with the following changes - set the ROOTPATH to a file that is owned by user and group informix with 644 permission (created as steps indicate in docs) - changed path names where appropos. - set DBSERVERNAME to the value of INFORMIXSERVER env var - changed J/Foundation stuff to use my box's JDK - set INFORMIXDIR, PATH, and INFORMIXSERVER appropriately However, when I call "oninit -i" (or any variant of this), I get "oninit: Fatal error in shared memory creation" The online.log file shows the following details: 23:22:36 shmget: [EEXIST][17]: key 52564801: shared memory already exists 23:22:36 mt_shm_init: can't create resident segment I basically get this same error no matter what command I run. Does anyone know what might be causing this? I've set up IDS 2000 on a RedHat box before, so I know that either I must be missing something small, or there's some sort of hardware conflict. Any help would be geratly appreciated. thanks, Matt Denny if it helps, I have the following configuration: env. vars: PATH=/opt/informix/bin:. . . INFORMIXDIR=/opt/informix INFORMIXSERVER=idsserver Also, here are teh contents of my onconfig file, located at /opt/informix/etc/onconfig (Apoogies for the line break problems due to cut and paste) #************************************************************************** # # INFORMIX SOFTWARE, INC. # # Title: onconfig.std # Description: Informix Dynamic Server 2000 Configuration Parameters # #************************************************************************** # Root Dbspace Configuration ROOTNAME rootdbs # Root dbspace nameROOTPATH /opt/informix/data/idsserver # Path for device containing root dbspace ROOTOFFSET 0 # Offset of root dbspace into device (Kbytes) ROOTSIZE 30000 # 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 rootdbs # Location (dbspace) of physical log PHYSFILE 2000 # Physical log file size (Kbytes) # Logical Log Configuration LOGFILES 6 # Number of logical log files LOGSIZE 1500 # Logical log size (Kbytes) # Diagnostics MSGPATH /opt/informix/online.log # System message log file path CONSOLE /dev/console # System console message path ALARMPROGRAM /opt/informix/etc/log_full.sh # Alarm program path TBLSPACE_STATS 1 # Maintain tblspace statistics # System Archive Tape Device TAPEDEV /dev/tapedev # Tape device path TAPEBLK 16 # Tape block size (Kbytes) TAPESIZE 10240 # Maximum amount of data to put on tape (Kbytes) # Log Archive Tape Device LTAPEDEV /dev/tapedev # Log tape device path LTAPEBLK 16 # Log tape block size (Kbytes) LTAPESIZE 10240 # Max amount of data to put on log tape (Kbytes) # Optical STAGEBLOB # Informix Dynamic Server 2000 staging area # System Configuration SERVERNUM 0 # Unique id corresponding to a OnLineinstance DBSERVERNAME idsserver # Name of default database server DBSERVERALIASES # List of alternate dbservernames NETTYPE # Configure poll thread(s) for nettype DEADLOCK_TIMEOUT 60 # Max time to wait of lock indistributed env.
