HI ? I must setting Linux and IIF200 on DELL PowerEdge 6400 server . that server has 6Gbyes main memory, 120Gbyes hard disk. first i have install Redhat 6.2 official. and i have upgraded kernel 2.4 from kernel 2.2.16 . ( because for awaring 6Gbyes main memory at Linux) last i have installed IIF2000 . I want to setting this system like this : main memory 6Gbytes awaring. Informix using more than 2Gbytes shared memory. i have some problems. default , 4G main memory awared at Kernel 2.2.16 . but informix can use only 700Mbytes shared memory . caused error shared memory when setting more than 700Mbytes.(at onconfig file) 6G main memory awared at Kernel 2.4 but informix can use only 700Mbyes shared memory. caused error shared memory when setting more than 700Mbytes.(at onconfig file) 6G main memory awared at Kernel 2.4 and kernel parameter setting( SHMMNI,SHMMAX,SEMMNI......) informix can not create any shared memory. I don't know what to do .... thank .

Run strace -o -f -F /tmp/1 oninit and look for the system call which fails man shmctl show give you the name of the system call to create shared memory! >thank . > > > > > > -- David Williams
