AIX Parameter change for concurrent users exceeding 100
We are doing capacity planning for our JDE system which is on E1 9.0/9.1.0.3 with all servers on AIX Power 7 machines. According to the document ID: E1: KER: Metadata Kernel Performance and Tuning Guide (Doc ID 820367.1) we must make following parameter change on AIX servers version 5 and above if concurrent user count exceeds 100 (page 3): Specific to AIX:
AIXTHREAD_SCOPE=S
export AIXTHREAD_SCOPE
We don't have this setting presently and our concurrent count will certainly exceed 100. Has anyone made this setting change before? If so then what are the implications of this change to current system and what will happen if we don't make this change and concurrent users grow beyond 100?
