  • Agenda

    Best Practices for Designing a Fusion Middleware 11g Infrastructure

    5

    maandag 10 oktober 2011

  • Normal Design Process1. Some product is bought (or build in-house) that

    runs on FMW 11g

    2. Buy some kit

    3. a DBA is sent to OU to get training

    4. The week after training DBA has to build and maintain a production platform with help from one or more developers

    5. Start running production (and into trouble... )

  • Gartner

    8 - 12 % TCO in Design + Develop + Test 88 - 92 % TCO in Maintaining

    7

    maandag 10 oktober 2011

  • Middleware is not Trivial

    Its (mission) critical Complicated: lots of moving parts Get involved in projects from the start

    Machine A Machine BAdminServer

  • Real Agenda

    1. Logical Design

    2. Physical Implementation

    3. Maintaining, the Full Life Cycle

    10

    maandag 10 oktober 2011

  • Logical Design

    11

    maandag 10 oktober 2011

  • Decide upon Definitions

    Before you design the infrastructure Brief your whole team (including

    management)

    Clear naming convention

    12

    maandag 10 oktober 2011

  • Document your Train of Thought

    Tedious but usefull for future use Dont wait till after the project /

    implementation

    Mark facts as facts and opinions as opinion Formulas and rules

    13

  • We Love Pictures

    Node 2Node 1

    SOA ClusterSOA

    CRS

    SOA

    CRS

    SAN 2SAN 1

    ACFS

    WLS WLS

    If its to complicated too draw on a diagram, its most likely wrong

    14

    maandag 10 oktober 2011

  • Segregation between Environments

    DTAP & SOD Separation of servers & network

    15

    maandag 10 oktober 2011

  • Design for Security

    SOD SSL whenever possible Also in DEV Firewall Connection Filters

    16

    maandag 10 oktober 2011

  • Dont mix Layered Products in One

    Domain

    oracle_common scripts dependencies on upgrade / patching

    17

    maandag 10 oktober 2011

  • Nodemanager:Domain vs Node

    Node specific: settings are domain wide Domain specific configuration Separation of OS users SSL trust-stores

    18

    maandag 10 oktober 2011

  • Separate System Components

    from Java Components

    Automatic network separation Different purpose

    19

    maandag 10 oktober 2011

  • Never run Apps in AdminServer

    Mixture of management tooling & customer applications

    Difficult troubleshooting

    20

    maandag 10 oktober 2011

  • Cluster Everything

    From the start (one node cluster) Find unexpected behaviour because of

    cluster as soon as possible

    Extending clusters is easy

    21

    maandag 10 oktober 2011

  • Separate Directories

    Use personal accounts for administrators Separate application users from

    infrastructure users

    22

    maandag 10 oktober 2011

  • Physical Implementation

    23

    maandag 10 oktober 2011

  • x86

    Weve only seen x86/x64 customers running Linux

    Buy the fasted kit you can get

    24

    maandag 10 oktober 2011

  • Scale-up vs Scale-out

    Larger JVM give more GC issues Our customers do scale-out SAME

    25

    maandag 10 oktober 2011

  • Virtualization

    Not for vmotion-like functionality Cloning (if you put the effort into it) Partition hardware

    26

    maandag 10 oktober 2011

  • Operating System

    Dont adopt a new OS because of WLS The best OS is the one youre an expert at

    27

    maandag 10 oktober 2011

  • Shared Storage

    NFS OCFS2 GFS2 ACFS rsync

    28

    maandag 10 oktober 2011

  • Shared Storage:take notice of

    HTTP lockfiles Large logfiles UCM tmpdirs

    29

    maandag 10 oktober 2011

  • Use VIPs whenever Possible

    Faster failover upon node failure Easier to rebuild on new node Logical separation of application and

    machine

    30

    maandag 10 oktober 2011

  • Get a LoadBalancer

    Performance Stability SSL offloading

    31

    maandag 10 oktober 2011

  • oraInventory in MW_HOME

    oraInventory only used by installers & oPatch

    self-contained package easier backups

    32

    maandag 10 oktober 2011

  • Separate Binaries from Configuration

    Replace binaries more easy Local disk for binaries Backup configuration

    33

    maandag 10 oktober 2011

  • Only use Java-based Nodemanager

    Easier to setup Lots of bugs exist for script-based

    nodemanager

    SSL is a pain on script based nodemanager (if not impossible)

    34

    maandag 10 oktober 2011

  • Separate AS from MS

    On different boxes Easier upgrade path No interference of management tooling (if you have the licenses)

    35

    maandag 10 oktober 2011

  • Setup AdminChannel(and port)

    Separate admin traffic from application Dedicated listen thread Has to run over SSL

    36

    maandag 10 oktober 2011

  • JDBC

    min-connections = max-connections Statement cache size < open_cursors FAN (GridLink) when on RAC

    See session #20942 13:15 on Wednesday

    37

    maandag 10 oktober 2011

  • Centralize Configuration

    No configfiles that need to be changed in JAR/EAR files

    No environment dependent ear-files. Easier to maintain

    38

    maandag 10 oktober 2011

  • Logging

    Centralize logging Logrotation on size + time Easier troubleshooting

    39

    maandag 10 oktober 2011

  • Standardize

    Troughout all environments Easier troubleshooting (at 2 AM)

    40

    maandag 10 oktober 2011

  • Automate

    Standardizes installation No differences between prod and test

    41

    maandag 10 oktober 2011

  • Test Test Test

    Find bugs before go-live Benchmark Stress test until break Predictable performance

    42

    maandag 10 oktober 2011

  • Maintainingthe full life cycle

    43

    maandag 10 oktober 2011

  • Track Changes

    Audit provider Record changes with WLST

    44

    maandag 10 oktober 2011

  • Record Incidents

    adrci:- Build-in fault diagnostibility infrastructure- Health monitor reports- Package incidents & problem information

    45

    maandag 10 oktober 2011

  • learn WLST

    mBeanbrowser Automating tasks

    46

    maandag 10 oktober 2011

  • Manage deployments

    Learn Ant CloningClient.jar No environment specific ear-files Plan.xml

    47

  • Out of PlaceUpgrades

    48

    maandag 10 oktober 2011

  • Grid Control

    Stack monitoring SLA checks Corrective action library

    49

    maandag 10 oktober 2011

  • MOSConfigurations

    Not OCM per-se Faster SR handling
