Agenda


Method proposed for Oracle on z projects

1. Scope of the project delimitation – feasibility study– Gather information on existing environment (servers, applications, network)– Fit for Purpose study– Prioritize the non-functional requirements (RAS, scalability, performance, management)– Assess the skills– Can follow a Cost & Value study (TCO)

2. Architecture design and sizing exercise– Select applications and servers to be consolidated (check support !)– Definition of the targeted architecture – Physical model development– Collection of performance and monitoring data from current distributed environment – Initial sizing exercise in collaboration with IBM Techline– First planning of the project

3. Proof of Concept– Functional Validation– Performance and Sizing Validation (if benchmark)– Targeted architecture validation– zLight can be a good option for a PoC, for functional tests only

4. Pre-production tests– Validation in the real environment– Environment health check before production (LPAR, z/VM, Linux, Middleware)– Skill transfer phase

5. Put to production– Iterative put to production– Monitor the system to tune it accordingly


Consolidation study: How to gather information about Oracle environment

� For System information– List of the servers models with details (constructor, model, CPU, cores, processor…)

� For workload information– Need to have an idea of the type of workload, if we have no information we take DB

production

� For CPU information– Best is to have vmstats, collected 1 or several days during a relevant period. Collect

interval should be at most 10min or less, if possible, with either• VMSTAT• SAR data• NMON

– If not possible to get the vmstats we need an estimation of CPU utilization during the peak period

� For memory information– To determine the quantity of about SGA and PGA sizes and memory used :

• AWR reports– About number of concurrent user connections:

• at the Linux level or AWR reports

‒ Protected investment: Features previously purchased are carried over on upgrade‒ Green solution: Reductions in power consumption - 40W/IFL, lowest carbon footprint‒ Centralised data, easier to manage: Backup/recovery, new deployment, fewer operational mistakes‒ Shared capacity can smooth out peaks: real reduction in IT footprint: MEASURABLE reduction in

Servers, storage, backup, network, licenses‒ Rapid deployment: A new LINUX VM including Oracle can be created in < 15 minutes, - Standby / test &

development systems occupy zero footprint until required‒ Server memory: z/VM, LINUX and Oracle support shared executables and very efficient memory usage‒ Stability: No need for disruptive swap out in the future.

What are z/VM 6.2 Single System Image and Live Guest Relocation

� z/VM Single System Image (VMSSI) – Optional priced feature that is new with z/VM Version 6.2. – Enables up to four z/VM systems to be configured as members of an SSI cluster, sharing the following

resources:• User directory• DASD volumes• User minidisks• Spool files• Network devices

‒ Members can be :• On the same or separate physical systems. • Can be either first-level or second-level z/VM systems.

– SSI enables the members of the cluster to be managed as one system, which allows service to be applied to each member of the cluster, avoiding an outage to the entire cluster.

� z/VM Live Guest Relocation– SSI introduces the concept of live guest relocation (LGR) – A running Linux guest operating system can be relocated from one member in an SSI cluster to

another without the need to stop the running Linux guest. – This capability provides

• Continuous availability during planned outages for software or hardware maintenance and allows system workload balancing.

• Helps to restart a z/VM system without causing disruption to the Linux guests within the cluster.– Relocation domains can be defined for business reasons


z/VM 6.2 Live Guest Relocation: Factors affecting relocation

A number of factors can affect the relocation:

� Virtual memory sizeThe more memory a Linux guest has, the longer the relocation and quiesce time.

� Virtual machine page change rateThe rate at which a Linux guest changes its pages in memory directly affects the total relocation time and, possibly, quiesce time. A Linux guest changing pages rapidly has more pages to relocate in each memory pass and so the memory move stage lasts longer.

� Inter-System Facility for Communications (ISFC) setup Faster channel-to-channel (CTC) speeds and the number of defined CTCs increase throughput and result in shorter relocation and quiesce time.Suggestions in Guidelines for planning your network in an SSI cluster

� Relocation options Relocation options can influence the relocation and quiesce time for relocation.

– SYNC - Synchronous - Only one relocation can be issued at a time by a particular user. Quiesce time is shortest when relocations are done synchronously because the relocations are not competing with each other for system resources. Using the default (SYNC) option on the VMRELOCATE command can help ensure relocations are done serially, especially if you are issuing the VMRELOCATE command in an EXEC.

– ASYNCH - Asynchronous - Using the ASYNC option on the VMRELOCATE command and issuing multiple relocations at one time might cause undesirably long quiesce times.

– IMMEDIATE - Causes quiesce time to occur after only one pass through memory. This option usually results in shorter overall relocation times, but longer quiesce times because the first pass through memory usually takes the longest, and the virtual server might have changed many pages, which then need to be moved during quiesce time.

– MAXTOTAL - Maximum total relocation time. The default value for MAXTOTAL is no limit.– MAXQUIESCE - Maximum quiesce time. The default for MAXQUIESCE is 10 seconds.

� Other non-relocation activityOther non-relocation activity on source and destination systems (constraints) might make relocation or quiesce time longer.


Oracle Live Guest Relocation on System z business value

� Availability– Improve applications availability (load balancing)– Help stopping a physical server (replacement, firmware upgrade, …)

• Planned software or hardware maintenance can be applied to a single member without affecting the other members of the cluster or disrupting running Linux guest operating systems.

• The Linux guests can be relocated to another member in the cluster prior to maintenance being applied to the original member that hosted the Linux guest.

• Systems Management is simplified in an SSI cluster. Service can be applied to z/VM from any member within the cluster, but it needs to be put into production on each member.

� Performance– Move server to free resources for other partitions– Move server to a more powerful physical server

� Flexibility– Move server to follow business needs– Move test servers to a production servers for real tests– Free a physical server for planned maintenance– Migration between z/VM maintenance levels

� Energy efficiency– Move partitions from under used physical servers to other servers to increase their resource usage and

their energy efficiency– Shutdown under used physical servers

� Avoid planned unavailability– Live guest relocations are initiated by a manual VMRELOCATE command. The command is not

automatically issued for any guest. – LGR is not a high availability solution, and it is not a disaster recovery solution.– Think of LGR as a continuous availability solution for the Linux guest.

Notice Regarding Specialty Engines (e.g., zIIPs, zAAPs and IFLs):

Any information contained in this document regarding Specialty Engines ("SEs") and SE

eligible workloads provides only general descriptions of the types and portions of workloads

that are eligible for execution on Specialty Engines (e.g., zIIPs, zAAPs, and IFLs). IBM

authorizes customers to use IBM SE only to execute the processing of Eligible Workloads of

specific Programs expressly authorized by IBM as specified in the “Authorized Use Table for

IBM Machines” provided at www.ibm.com/systems/support/machine_warranties/machine_code/aut.html (“AUT”).

No other workload processing is authorized for execution on an SE.

IBM offers SEs at a lower price than General Processors/Central Processors because

customers are authorized to use SEs only to process certain types and/or amounts of

workloads as specified by IBM in the AUT.
