- How can you tell the absolute limit of processes that can run on your
- AIX system?
-
- The pstat command with the -T flag supposedly displays changeable
- system variables:
-
- # pstat -T
- SYSTEM VARS:
-
- buffers 20
- files 968
- e_files 968
- procs 131071
- e_procs 96
- clists 16384
- maxproc 40
- iostats 1
- locks 200
- e_locks 8521808
-
- Does anyone know what these signify and how to get at them? I have
- been through info (AIX 3.2.2), and through the Performance Monitoring
- and Tuning Guide. No help. I believe maxproc is the maximum number of
- processes a user can run at once; at least, smit will tell you that,
- and this number matches it on various systems. Are we barking up the
- wrong tree with pstat?
-
- This started because one of our systems crashed with "no more processes."
- That naturally started us wondering how many processes the system can
- run. I don't find any variable like that in any of the /usr/include/*.h
- files or /usr/include/sys/*.h files, which makes me wonder how the
- system decides it has no more processes.
-
- The pstat -T command on a Sun is much friendlier. It answers in English,
- and you don't have to be root to run it:
-
- joann@cadhub> pstat -T
- 244/582 files
- 199/322 inodes
- 54/138 processes
- 7520/131600 swap

- Neither Stanford nor the DOE would be caught dead with these opinions.
- Nor do they consult me when formulating theirs.
