Hi all, In the last few days i have been discussing with a co-worker about how WLM balance batch Workload. We're z/OS 1.10 and the distribution of jobs among the JESPLEX does not seem to be smarter than in older releases.
I've read that after z/OS 1.8 the algoritm would be enhanced, but the only thing that i found out is a JES2 command ($TJOBCLASS(x),XEQ(xxxx)=(MAX=nn) ) that limits the maximum number of jobs for each member of JESPLEX. There is another command ($TMASDEF,WLMPERF=YES/NO) that should do something but i could not find it documented in any IBM manual. Actually, the manual informs that the intention is not to reach an equally balanced distribution of batch jobs over the JESPLEX. WLM keeps starting inits while CPU is less than 95% utilization even with idle capacity in others systems. What enhancement is this ?
