we are tried setup CENTOS 4.6 with Informix Dynamic server version 10 UC8 on DELL 6800.

 

The problem we have is while doing bdatabase backup (ontape), we have error happen.  I guess the error come from "semaphoe".  server semaphore are:

 

# sysctl -a|grep sem
kernel.sem = 250        32000   128  128

# sysctl -a|grep shm
vm.hugetlb_shm_group = 0
kernel.shmmni = 4096
kernel.shmall = 4194304
kernel.shmmax = 2147483648

 

Does anyone has ideal what semaphore should setup in Informix?

 

Thanks.
