I seem to remember that SyncSort offers an Add-On package that allows certain SyncSort processing to be offloaded to zIIPs. The above statement suggest that SyncSort's perfocmance is suffering from using zIIPs (simplified and exagerated, I know). Also "IBM Sort for DB2 for z/OS" (can't remember the exact name), is offloading to zIIPs, if I remember correctly. This procuct is based on SyncSort code as far as I understand. -- Peter Hunkeler -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: CERTAUTH vs SITE vs user certificate
In RACF: 1. Only Certificate Authority(CA) certificate SHOULD issue certificates for others - for a user, for a server, for another CA. 2. For a self-signed CA certificate, we call it a root certificate. 3. A CA certificate signed by another CA is called an intermediate CA. 4. CA certificates including root or intermediate are owned by a special ID CERTAUTH. 5. User certificates are owned by an ordinary RACF user ID. 6. Server certificates can be owned by an ordinary RACF user ID or by a special ID SITE. 7. In the original support when the FACILITY class is used to control the access of the private key of the certificate in the keyring, we need the certificate owned by SITE in order to share the private key by giving the ID of the application CONTROL access to IRR.DIGTCERT.GENCERT. That's the reason of having SITE as the owner. But in V1R10 when RDATALIB class was introduced, this restriction was lifted, the owner does not need to be SITE. 8. Having SITE as the owner of a server certificate is logical. Having an ordinary ID as the owner of a server certificate has the benefit of enabling the same ID to own the key ring. Key ring can not be owned by the SITE ID. 9. In validation process, SITE certificate can be used by a certificate validation application that honors it without checking the whole chain of CAs. But I don't know if any common certificate validation application running on z/OS honors it yet. 10. Go back to #1, I said SHOULD. But RACF supports SITE to issue certificates too. I don't find a scenario that needs this support though.

Re: CERTAUTH vs SITE vs user certificate
Maybe take a look at the Digital Certificate Goody Bags on z/OS presentations or something like Security Server RACF Security Administrator's Guide (SA23-2289), Using RACF to manage digital certificates: RACF has three categories for managing digital certificates: User certificate A certificate that is associated with a RACF user ID and is used to authenticate the user's identity. The RACF user ID can represent a traditional user or be assigned to a server or started procedure. Certificate-authority certificate A certificate that is associated with a certificate authority and is used to verify signatures in other certificates. Site certificate A certificate that is associated with an off-platform server or other network entity, such as a peer VPN server. This category of certificate can also be used to share a single certificate and its private key among multiple RACF user IDs. When used for sharing, a certificate might be referred to as a placeholder certificate.

Re: DFsort and zIIP
Andy, DFSORT can use zIIP on behalf of DB2 utilities, but not otherwise. Here's more information: At this time, IBM has no plan for enabling DFSORT to exploit the system z9 Integrated Information Processor (zIIP). IBM realizes DFSORT remains a prominent component of our customers' batch workloads. However, the added controls that would need to be implemented in order to maintain our high standards for performance, reliability and system integrity are not justified in view of estimations that there is a low offload potential and the value to clients may be marginal. IBM will continue to focus its DFSORT development efforts on the enhanced function, performance, reliability and service items that we believe provide the most value to our clients. The foregoing represents IBM's current intent and is subject to change. DB2 Utilities Suite for z/OS uses a small set of DFSORT sort function. Worldwide, there has been a tremendous increase in DB2 for z/OS activity (due to such things as database consolidations, remote connectivity, business intelligence, and specialty engine exploitation). This increase in DB2 activity has led to an increase in database maintenance workloads which often drive bursts of parallel utility processing during scheduled maintenance windows. As a result, additional offload by DB2 Utilities Suite for z/OS is supported.

SMT is not about new instructions; it means a single processor can appear to be two. In other words, it can have two tasks dispatched on it concurrently. All processor types support SMT, but z/OS will never enable SMT on a CP, while you can configure z/OS to enable SMT on zIIPs. -- Pew, Curtis G curtis@austin.utexas.edu ITS Systems/Core/Administrative Services -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

FAMS?

Possible resources to assist in evaluations of new hardware: #1. Start gathering SMF 113 records "Hardware Instrumentation Services" (HIS) (z10's and up). #2. Use the zPCR tool: http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/PRS1381 Also remember, if you are going to a z13 system, there are new hardware instructions that use the zIIP engines, not just JAVA.

How large an RSA does ATTACHX provide to the subtask?

This was apparently updated in z/OS 2.1 (as it is correct in the z/OS 2.1 knowledge center).

There really is no "but" since there is no conflict between the two. "It" referred to the register save area provided to the attached routine (which does get a 144-byte save area). The ETXR is a different matter. IRBs (and the ETXR is one) do not in general get a 144-byte save area.
