Prior to to z/OS 1.3 (i.e., some 15 years ago) there were reasons for increasing the value of the ERV parameter and from time to time one can still see values of up to 50,000. Since the ERV is being restarted there are no good reasons for such exaggerated values and I'd consider the default of 500 to be good.
And just to extend the topic a bit - the IEAOPT parameters that one would frequently want to specify non-default values for are: -CPENABLE=(10,30) -ManageNonEnclaveWork=Yes (when using WAS/Liberty with enclave management) -BLWLIntHD=5 for more aggressive blocked workload support, namely for DB2 And for both RCCFXET and RCCFXTT AUTO should be in place. Then there are a few that deserve consideration, such as INITIMP=E, MT_ZIIP_MODE=2. It is possible that the defaults will eventually change:-) Horst Sinram - STSM, IBM z/OS Workload and Capacity Management ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
