Title: RAC+ASM: Lessons learned after 2 years in Production

**** Presented by Christo Kutrovsky, The Pythian Group ****


Managing over 70 databases for 4 major customers, I have some good stories to share. Running almost all possible combinations of ASM, RAC, NETAPP and NFS.

Success, failure and gotchas. This presentation is the equivalent of years of experience, condensed in major highlights in 45 minutes. To list a few stories:

  • – Migration via LUN re-assignment
  • – Migrating online migration from EMC to 3par
  • – Removing ASMLIB and using EMC multipathing
  • – Gotchas when building ASMLIB devices with multipathing
  • – Corrupting your production database beyond repair with duplicate database on ASM
  • – Overwriting your data with ASM due to incorrect naming convention
  • – Corrupting your production database with NETAPP/NFS due to Oracle bug
  • – 2 nodes RAC is not HA – performing network maintenance
  • – RAC + SAME = LAME

Start time: Thursday, March 3rd, 2011, 9:00am Pacific / 12:00 pm Eastern The presentation will last one hour.
