Portions of the following DB2 for z/OS V8 workloads may benefit from zIIP*1. CRM application serving

• Siebel CRM and data warehousing applications running on UNIX, Linux, Intel, or zLinux accessing DB2 for z/OS V8 via DRDA over a TCP/IP connection.

2. Data warehousing applications*• Siebel Business Analytics requests that utilize parallel queries

3. DB2 for z/OS V8 utilities*• Internal DB2 utility functions used to maintain index maintenance structures

* The zIIP is designed so that a program can work with z/OS to have all or a portion of its enclave Service Request Block (SRB) work directed to the zIIP. The above types of DB2 V8 work are those executing in enclave SRBs, of which portions can be sent to the zIIP.

New Specialty Engine

DB2 V8 exploitation of IBM zIIP can add value to database workloads

•Webcast replay ibm.com/servers/systems/z/2006/


The zIIP is designed so that a program can work with z/OS to have all or a portion of its enclave Service Request Block (SRB) work directed to the zIIP. The types of DB2 V8 work listed below are those executing in enclave SRBs, portions of which can be sent to the zIIP.

Example 1 = Distributed SQL requests (DRDA)

Queries that access DB2 for z/OS V8 via DRDA over a TCP/IP connection are dispatched within z/OS in enclave SRBs. z/OS directs a portion of this work to the zIIP.

Example 2 = Parallel query (BI)

Parallel queries will now use enclave SRBs. z/OS directs a portion of this work to the zIIP.

Example 3 = DB2 utilities for index maintenance

DB2 utilities LOAD, REORG, and REBUILD will now use enclave SRBs for the portion of the processing that is related to index maintenance. z/OS directs a portion of this work to the zIIP.

Estimate Guidelines – Star Schema

Only parallel query processing– Portion of the child task processing – Main tasks coming in via DRDA via TCP/IP can take

advantage of the DRDA use of zIIP.

The combined child & main tasks coming in through DRDA via TCP/IP is expected to yield additional processing eligible for zIIP.

Longer running queries see higher benefit.

The possible benefit to a data warehousing application may vary significantly depending on the details of that application.

Lower end of range is expected with: – tables with fewer indexes– fewer partitions– compression used

Higher end of range is expected with:– Tables with many indexes or many partitions

What is DRDA?

ApporDB

DRDA

DB

DRDA = Distributed Relational Database Architecture– Developed by IBM– Enables relational data to be distributed among multiple

platforms – ‘any app to any db and any db to any db’. Applications and APIs accomplish the actual implementation

DRDA is native to DB2 for z/OS. It reduces the need for additional gateway products that may affect performance and availability

The Open Group adopted DRDA in 1998 as the open standard for database access interoperability

An application uses DRDA application requestor or server to access a remote database (DB2 Connect is an example of a DRDA applicationrequestor)

Uses TCP/IP or SNA as a network protocol to flow DRDA commands

So.... regarding the zIIP: if DB2 for z/OS V8 work load comes over TCP/IP and is DRDA compliant, a portion of that DB2 workload is eligible to be redirected to the zIIP – you need BOTH TCP/IP and DRDA.


What is index maintenance?

An index allows quick access to the rows in a table. Indexes are created using one or more columns of a table.

Over time, as data in a large database is manipulated indexes can become less efficient. They need to be updated and maintained. This can be a very big task.

– LOAD-- loads your tables – REORG– improves your index performance – REBUILD INDEX-- creates or rebuilds your indexes

So.... regarding the zIIP: The BUILD phase of LOAD, REORG, and REBUILD utilities performs index maintenance. Most of the BUILD phase is eligible to be redirected to the zIIP.


What are enclave SRBs?z/OS dispatches DB2 work in either TCB (Task Control Block) mode if request is local or SRB (Service Request Block) mode if request is distributed. Under these modes of operation the parallel tasks are assigned the same importance as the originating address space.

Preemtable enclaves are used to do the work on behalf of the originating TCB or SRB address space. Enclaves are grouped by common characteristics and service requests and since they are preemptable, the z/OS dispatcher (and WLM) can interrupt these tasks for more important ones (ie manage a transaction end-to-end). There are two types of preemptable SRBs: client SRBs and enclave SRBs.

If the DB2 for z/OS V8 request is coming in over distributed (ie DRDA over TCP/IP) then that work is executed in enclave SRBs. If the request is coming over local/ native connection, then that work is dispatched between TCBs, client SRBs, and enclave SRBs (star schema queries and index maintenance now use enclave SRBs)

So...... regarding the zIIP, only the enclave SRB work (not the client SRB work) is eligible to be redirected to the zIIP.

DB2 V8 knows how its work is dispatched and directs z/OS 1.6 to dispatch (redirect) a portion of the eligible work to the zIIP.
