Hi Don, I concur with Sam. Scheduling work as an Enclave SRB is necessary, but not sufficient. You must also use an IBM licensed API to define/manage the Enclave's zIIP eligibility. The API is part of the materials that IBM may license to ISVs.
More to the point of your question... As part of our zIIP-enablement R&D we compared the cost of: (a) frequently starting Enclave SRBs, and (b) using a "persistent" Enclave SRB in conjunction with MVS Suspend/Resume services. We actually ended up using both techniques in our product (although in different situations).

You need to sign a license and confidentiality agreement to obtain documentation needed to run on a zIIP. License is only available to ISV devs. ,ot to in-house commercial cust.

It is my understanding that to do this I must schedule an enclave SRB. I am confused here. WLM is involved and there seems to be more to this. Can anyone explain? My only purpose in using the zIIP is to reduce the GP CPU usage, so I plan on issuing a dependent enclave SRB and wait for it to finish. Does anyone have any gotchas to share? I know this is contrary to SRB designed but would it be more efficient to have one preemptable SRB running forever and use wait and post to control or simply schedule the SRB and wait for it to complete? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN Sent from my Verizon Wireless BlackBerry ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
