Important My e-mail ---> mmico@colorobbia.es I have had the same problem with AIX 4.2.1 and Informix OnLine 7.22UC2. The solution was to increase the size of new shared memory segments because on AIX their is a limit of 10 shared memory segments. I don't know if is possible to change this limit. But it was easier to me just to change the SHMADD parameter i the onconfig file and then recycle the Informix Server. You can also increase the SHMVIRTSIZE parameter to prevent the Informix Server to make to many new shared memory segments. Make onstat -g seg -- and count the numbers of shared memory segments . Make onmode -F -- free unuseed shared memory segments From onconfig : SHMBASE 0x30000000 c Shared memory base address SHMVIRTSIZE 8000 c initial virtual shared memory segment SHMADD 4096 c Size of new shared memory segments (Kbyte) SHMTOTAL 0 c Total shared memory (Kbytes). 0=>unlimited Hope this will help you.
