April 16,2002 SOLARIS: INCREASING THE NUMBER OF SHARED MEMORY RINGS Under Solaris 2.6 (and probably other versions as well), the maximum number of shared memory segments is six. This means that on an out-of-the-box machine you can only configure six rings. If you try to configure more than that, you will see a cryptic message from tport_create about too many open files. The fix to this problem is to add the following lines to the /etc/system file, and then reboot the system. set shmsys:shminfo_shmmax = 4294967295 set shmsys:shminfo_shmmin = 1 set shmsys:shminfo_shmmni = 100 set shmsys:shminfo_shmseg = 20 set semsys:seminfo_semmns = 200 set semsys:seminfo_semmni = 70 This allows for 20 rings.
