Memory Usage on Informix 7.24

Hi, everybody=20 I have a question and hope you could give me suggestions. Now, we are = developing an application on NEC UP machine (UNIX) with Informix 7.24. = After starting up Informix, we use onstat utility to see how many memories = used by Informix. The result is the same as our settings in onconfig file. = That is, 80MB for buffer and 32MB for shared memory. However, when we use = UNIX ps command to see how many memories used by Informix processes = (virtual processors), the outcome makes us surprised: they use more than = 300MB=21 In our setting, we have six physical processors and 10 AIO = virtual processors. They allocate 16MB memory each=21 I am very confused, = I believe there must be some things wrong. I don=A1=AFt believe Informix = occupy so many memories. But, I don=A1=AFt know what happened exactly. = Would you like to give me a reasonable explanation?=20 Thank you in advance.=20 best wishes, lix=20

All is well. Art S. Kagel
