  (2.31B)
• Linux RDBMS has 4.2 percent
• Oracle has 69 of the Linux RDBMS market
• Up 360
• Oracle 9i RAC Clustering a big factor
• IBM Linux has 28.5 of the Linux RDBMS market

Migrations Project Considerations

• Certified OS and Software versions
• Pre-requisite Patching
• Create and Upload Manifest
• Upgrade Dot Release and Migrate
• Upgrades Applications New functionality
• Users need to test at least once for migration
  and upgrade

10
Migrations Project Considerations

• Migrate
• Users need to test migration
• Future upgrade requires additional testing
• Production Cutover
• Downtime
• Post Go-Live Support
• Operating System Support
• Training vs. Outsourcing

11
Project requirements

• Timeline
• Database migration to Linux
• Applications migration to Linux
• Resource requirements
• Database Administrator (full time)
• Testing Team (functional and technical resources)

12
Linux Platform Migration Utility

• Provides a way to quickly move an existing Oracle
  Applications
• Includes Technology Stack Upgrade to 11.5.10
• Retains exact application patch level therefore
  no APPL_TOP/Database synchronization is necessary
• Retains many customizations

13
Migrate Oracle Applications to Release 11i

• High level steps
• Apply Migration utility patch
• Generate and upload manifest
• Copy source files and directories to Linux
• Install 11.5.10 Tech Stack
• Configure applications on Linux
• Documentation Metalink Note 238276.1

14
Migrate database to Linux

• High level steps
• Export source Release 11i database (any OS)
• Prepare a target Release 11i database (Linux)
• Import target Release 11i database (Linux)
• Update imported Release 11i database (Linux)
• Documentation Metalink Note 230627.1

TUSC working with Linux

• Supported an Online E-Commerce site a 4 node 10g
  RAC cluster on RHEL 3.
• Upgraded standalone / Windows / 8i to 9i RAC on
  Linux RH Enterprise 3.0. (Performance improved
  quite a bit)
• 9204/RAC database on Red Hat ES 2.0.
• Upgrade from 8.1.7 on SCO to 9.2.x on Red hat ES
  2.0.
• Conversion for ERP from 8.1.7/Win32 to 10g on Red
  Hat 3.0.
• Moving a 3-node RHEL RAC to 6-node.

16
TUSC working with Linux

• 2 articles on OTN on installing/configuring 10g
  single instance and 10g RAC on every Linux
  version supported by Oracle.
• 3 presentations on the RAC SIG website.
• TUSC RAC class uses a two-node Linux cluster
  using a single firewire shared drive for storage.
  It runs both 9.2.0.4 and 10g RAC on the same
  cluster without problems. Of course, it's not
  meant to perform well, just to demonstrate
  functionality.
