Oracle Confidential

  11. Taking It To The Next LevelWith ASM in 11gR2 Oracle Confidential

  12. Oracle Grid Infrastructure(ASM + Oracle Clusterware) • ASM and Oracle Clusterware integrated and installed in a single ‘Grid Infrastructure’ home • Integrated installation, configuration and upgrade • Installed using Oracle Universal Installer (OUI) • Not a part of database install • Option to minimally configure ASM and ACFS • Automate creation of Oracle DB Homes on ACFS Oracle Confidential

  13. ASM Configuration Assistant (ASMCA) • One tool to initialize & manage * Disk Groups * Dynamic Volumes * ACFS file systems • Manage ASM before db install • Upgrade previous versions of ASM to the current version (11g R2) Oracle Confidential

  14. Dynamic Volume Manager ACFS FSOracle Bin 3rd PartyFS Extending ASM to Manage ALL Data Database RAC Application 3rdParty FS Automatic Storage Management (ASM) ACFS Snapshot ASM Instance Managing Oracle DB Files ASM Cluster & Single Node File System (ACFS) General Purpose Files Database Files ASM Disk Group Dynamic Volumes DB Datafiles DB Datafiles Database files OCR & Voting files Oracle Confidential

  15. What is ASM Dynamic Volume Manager • A new cluster (and single host) volume management service • Standard disk device interface to clients • Loadable kernel driver • Dynamic Volume is a volume file created in an ASM disk group (new file type ‘asmvol’) • An OS device file is created automatically when a dynamic volume is created • Managed by SQL/ASMCMD and EM OS /dev/asm/vol1-123 ASM DG +DATA/vol1 Oracle Confidential

  16. What is ASM Cluster File System (ACFS) • General purpose scalable file system • Journaling, extent based • Single node and cluster • POSIX, X/OPEN file system solution for UNIX/Linux • Windows file system solution for Windows platforms • Accessible through NAS protocols (NFS, CIFS) • Leverages ASM technology for volume mgt • Integrated with Oracle Clusterware for cluster support • Multi OS platform (Linux and Windows at initial release) • Integrated with Oracle system mgt tools • Oracle installation and configuration • Enterprise Manager and ASM Storage mgt tools • Native OS File System Management tools Oracle Confidential

  17. What are ACFS Snapshots • Dynamic,fast, space efficient, “point in time” read-only copies of ACFS file system files • Captures ASM FS file block/extent updates • An enabler for: • On-line, disk-based, file backup model using snapshots • Individual file recoveries • Up to 64 snapshot images per ASM file system • Policy based snapshots: • Schedule snapshots on an interval basis: every 5 seconds, every 30 minutes, daily, … • Create an ACFS snapshots • acfsutil snap create snap_namemountp Oracle Confidential

  18. 1 1 Leveraging the Power of ASM ACFS File System: /usr1 • Even distribution of data • Dynamic provisioning • Dynamic volumes and ACFS FS may be resized leveraging ASM file resize features • % asmcmd volresize dga vol1 -s 50G • Can also use Enterprise Manager for management and threshold alerts ACFS file A ACFS file B Mirrored Mirrored Linux: /dev/asm/vol1 Win: \\.\asm_dgname_volname +DATA/dga/vol1 3 Primary ASM File Extent Mirrored ASM file Extents Oracle Confidential

  19. Managing the Dymanic Volumes and ACFS File SystemIs Simple And Flexible • Native Linux, UNIX, and Windows OS file system commands and extensions • acfsutil platform independent commands • ASM Configuration Assistant (ASMCA) • Enterprise Manager Oracle Confidential

  20. An Example: Creating an ACFS File System $ mkfs -t acfs -b 4k /dev/asm/volume1-62 ; Create fs on ASM volume $ su - root # mount -t acfs /dev/asm/volume1-62 /tmp/images# su – oracle_usr $ acfsutil registry -a /dev/asm/volume1-62 /tmp/images$ mount –t acfs –o all none none ; Mount everything in the registry $ cd /tmp/images $ cp /home/my_images . Oracle Confidential

  21. ACFS Use Cases • Oracle Home • Shared or node-local • Not Grid Infrastructure home • External files • Application binaries • Not an OS boot FS Oracle Confidential
