Oracle Grid Infrastructure Installer (12c Rel. 1 & Earlier) •  Shiphome-‐based release – a proprietary format • Unzip and execute ‘runInstaller’ to get the so^ware • Configure Oracle Grid Infrastructure and Oracle ASM

– Trend is to use ‘config.sh’ a5er patching the so5ware •  Supports interacIve and silent mode deployments • Other tools/scripts included in the Oracle GI Home:

– addNode.sh – to add more nodes to the exisIng cluster – config.sh – configures/upgrades the clusterware – clone.pl – registers a home in the inventory via a single-‐node opera7on

Oracle Grid Infrastructure Installer 12c Release 2

•  StarIng with Oracle Grid Infrastructure 12c Rel. 2, the Grid Installer uses a gold image instead of the tradiIonal shiphome as installaIon media

•  The zip-‐file available for download is therefore a 12.2.0.1 base gold image •  The launch script is gridSetup.sh or gridSetup.bat • User-‐created (customized) gold images are supported

– Customiza7on can include PSUs and / or addi7onal patches

•  The new deployment process has no impact on any post-‐install so^ware lifecycle management operaIons; e.g. adding nodes, cloning, patching

gridSetup – The New Installer Swiss Army Knife Part 1

• New opIons supported with gridSetup: – PSU can be applied [-‐applyPSU] – OneOff patches can be applied [-‐applyOneOffs] – Run from network loca=on and deploy to local path [-‐des=na=onHome] – Execute post-‐install configuraIon tools [-‐executeConfigTools] – Execute root scripts automaIcally in silent install using sudo/root

– Installer can be patched [-‐applyInstallerUpdates] – Gold-‐image can be created from an exis7ng GI home [-‐createGoldImage]

gridSetup – The New Installer Swiss Army Knife Part 2

•  Improved cloning, addnode and post-‐install configuraIon •  Supports mulI-‐node so^ware-‐only install of GI home

– Compare with cloning so^ware to mulIple nodes in one go

• Can be launched from a so^ware-‐only home – to configure the so^ware (config.sh replacement) – to add more nodes to the to-‐be-‐configured cluster

• Can be launched from a configured home to execute config tools

18

So5ware management support


(Re-‐) Execute Post-‐Install ConfiguraIon Tools

• Works for gridSetup (GI) and runInstaller (DB, Client)

• Provides interacIve UI & works with the installer’s response file

• BeWer logging of configuraIon tools output for easier diagnosability – configToolAllCommands is deprecated

19

gridSetup … -‐executeConfigTools


gridSetup Enhancements

20

Future 12c Rel. 2 enhancement

• Ability to re-‐run configtools of a failed/aborted installaIon • Ability to re-‐run root.sh • Ability to move GI to a new home


Large Cluster Support Part 1

• With 12c Rel. 2, Oracle GI installer supports ‘Lenient’ mode installaIon

•  Installer allows for eliminaIng nodes that are mis-‐configured & to proceed with the remaining nodes

•  It is default behavior for all interacIve installaIons

•  Supported for silent (non-‐interacIve) installaIons when “-‐lenientInstallMode” is specified on command line

Introducing Gold Image as a Service (GIaaS)

• Oracle internal, centralized service to deliver ‘Gold Images’ •  Simple & REST-‐enabled web portal offering ‘Gold Images’ of Oracle Homes • Users can choose a base release plus any PSU or OneOff required • Uniform and cost-‐effecIve way to deliver customized Oracle homes • GIaaS detects conflicts, builds, validates, and op7mizes the image • Output format -‐ tar, zip or Docker container •  Images uploaded to Oracle Cloud Object storage

27

Currently Oracle internal only


Get the patched so^ware as a docker container


Allows input of exisIng inventory

Allows custom database template


Rapid Home Provisioning (RHP) and Maintenance

•  Complex build process repeated for each node

•  Error prone •  Longest down-‐Ime and maintenance window

•  Have to create backup (no built-‐in fallback plan)

•  How do you enforce standardizaIon?

•  Build gold image once, use everywhere

•  Fewest steps, simplest process

•  Shortest down-‐Ime and maintenance window

•  Built-‐in Fallback •  Built-‐in standardizaIon

•  Complex build process repeated for each node

•  Error prone •  Shorter down-‐Ime and maintenance window

•  Built-‐in Fallback •  How do you enforce standardizaIon?

What is the best way to apply maintenance?

Update in Place Clone, Update and Switch Deploy Gold Image, Switch


•  Dri^ not seen unIl scan takes places

•  Scanning unchanged targets is unnecessary work

•  Does not prevent dri^

•  No Ime lag between dri^ and alert

•  No extra work •  Does not prevent dri^

32

•  Locked configs cannot dri^ •  Can trigger alert if unauthorized changes aWempted

•  Can trigger alert if authorized changes made

What is the best approach to handling so^ware dri^?

Scan

Trigger Alert

Prevent


Streamline the DistribuIon Process

•  Ship only once – To a customer, to a site, to a pool

•  Ship to interested parIes only – Subscribers

•  Ship only what is necessary – Updated Modules, Updated Files, Updated Blocks

• Deploy non-‐disrupIvely – Ship any Ime, choose when to use it

33

Customer


•  Simple •  Prevent errors, enable easy correcIons •  Use Gold Images for all scenarios •  Enable mass operaIons on 1000s of nodes

12.1.0.2 Custom

RHP Server •  Uptake current estate by promo7ng exis7ng homes to gold images

•  Create new homes and promote to gold images a5er valida7on

•  Assign states to images for lifecycle management

GRID 11.2.0.4.3

WLS 12.2.1

•  Oracle internal users: import image from GIaaS Grid


Supported targets and environments Manage exis7ng and create new Pools, Homes, and Databases

• Patch and Upgrade exisIng deployments – No pre-‐requisites (config, agent, daemon…) for targets – Database and Grid Infrastructure 11.2.0.3, 11.2.0.4, 12.1.0.2, 12.2.0.1

•  Provision, Scale, Patch and Upgrade new Clusters and Databases – 11.2.0.4, 12.1.0.2, 12.2.0.1

• Bare metal, VMs, CDBs, non-‐CDBs •  SI (standalone, Restart, Grid Infr), RAC One, RAC •  Linux, Solaris, AIX • Generic so^ware homes


Easy to create Server, start managing current estate

• RHP Server fully self-‐contained – Commodity hardware or engineered systems, can be clustered for HA – Enable with single srvctl command – Lightweight -‐ can co-‐exist with other funcIons

• No new so^ware needed on targets • No run-‐Ime dependency between Server and targets

Revamped DBCA

Revamp of UI Enhanced validaIon with unique error code New command line interface

39


Duplicate Database CreaIon Support

•  Supports creaIng Single Instance duplicate databases

• Can be used for creaIng standby databases for example

•  Storage customizaIon during duplicaIon

40


SelecIve Component ConfiguraIon for PDBs

•  Allows for choosing whether a parIcular opIon is installed for a PDB

•  Equivalent command line opIons are: –  [-‐dbOpIons <A comma separated list of name:value pairs with database opIons to enable/disable. For example JSERVER:true,DV:false>]

–  [-‐pdbOpIons <A comma separated list of name:value pairs with database opIons to enable/disable. For example JSERVER:true,DV:false>]

41


Enhanced PDB Management FuncIonality

•  Local UNDO tablespace per PDB • Modularized storage locaIons for PDBs

• Can create addiIonal PDBs when creaIng CDB from CDB template

• Rename PDB names during CDB creaIon from CDB template

42


Clone Template CreaIon with Zero DownIme

• DBCA can take Hot backup of database • Database has to have archive log mode enabled.

43

Not every database is unique


Summary

44

Gold image-‐based deployments are trending
