!  Availablity requirements

!  ASM Cluster File System Overview

!  Fields of applicaAon !  New Features 11.2.0.2 /11.2.0.3 !  Licensing !  Summary



Availability requirements

!  Permanently increasing requirements on availability

!  DownAme of business-‐criAcal applicaAons unimaginable

!  Data loss can jeopardize existence

!  As well with limited budget



Availability requirements

!  On occurence, downAmes have to be resolved immediately



Review High Availability

!  Basic system




!  Failover cluster




!  Real ApplicaAon Cluster




!  (Extended) Distance Real ApplicaAon Cluster




!  Standby




!  Oracle technologies focused on Oracle Databases !  External data not considered !  ProblemaAc with: – BFILEs – SQL*Loader – External Tables – etc.




!  Local File Systems




!  3rd Party Cluster File System / OCFS




!  NFS / CIFS / Samba




!  Failover File System




!  Local High Availability

!  ReplicaAon to second locaAon sAll requires addiAonal soluAons

!  High maintenance effort

!  Interference in mulAple areas with high complexity




!  Important limitaAon on Standard EdiAon RAC


Oracle Database Licensing Informa4on / Special-‐Use Licensing:

No other cluster so,ware can be installed on the system, including OCFS, OCFS2, third-‐party clusterware, third-‐party cluster volume managers, and third-‐party cluster file systems.


Oracle ACFS

!  Enhances ASM by storing all „none-‐database files“:

– Oracle Homes und Logfiles

– ApplicaAon data

!  POSIX/X-‐OPEN compliant file system mainly for cluster environments



Oracle ACFS

!  Enables sharing data via: – NFS – CIFS

!  Rounds out ASM as a complete storage soluAon

!  Based on the exisAng management features



Structure of Oracle ACFS



ACFS Features

!  MulAplakorm cluster file system

!  Unified mulAplakorm soluAon

!  UAlizaAon of all ASM disk group management features:

– Add / Remove disks – Rebalancing – Mirroring



ACFS Features

!  Online size adjustments:

– Expansion

– ReducAon (limited)

!  Customizable mirror protecAon

!  Snapshots



Fields of ApplicaAon

!  No longer limited on NAS / 3rd Party CFS

!  Storage Mirroring




!  (Extended) Distance RAC



Benefits

!  Unified mulAplakorm soluAon

!  No longer limited to NAS or Cluster FS soluAons

!  Make use of synergies

!  Less management effort

!  Reduced costs (in terms of storage replicaAon, mirroring, etc.)
