Topics

• Patching Best Practices

• 11i.10 Maintenance Improvements

• Case Study: Pella

• Maintenance Initiatives

Best Practices

• Keep up-to-date on latest AD/OAM code

• Schedule periodic, proactive maintenance

• Combine patches with AD Merge Patch

• Perform “uptime” maintenance• Gather schema stats• Apply translation database updates• Patch help system• Select data migrations

• Use a Shared File System and Distributed AD

• Use a Staged APPL_TOP

• Use cheaper, faster hardware

Production Uptime

Cheaper, Faster Middle-tier Hardware

• Linux RHEL 3, RHEL 4, SLES 9

• 2 CPU / 6GB with shared storage

• Shared Application Tier File System

(merge APPL_TOP process now available)

• Linux Migration Process

Linux Migration Process

• Migrate middle-tier in about 13 easy steps

• Only a few minutes of downtime

• Retains current patch level

• Retains many customizations

• Includes tech stack upgrade

11.5.10 Upgrade Timing (does not include Pre or Post steps)

Serial Install

Staged APPL_TOP

Purge/Dbase changes

Patches

More horsepower

▼Patches to improve performance – 32 hrs reduced to 23 hrs

▼Upgraded hardware – more horsepower – 23 hrs reduced to 12 hrs

▼Working closely with Oracle Support, Critical Care, Advanced Performance Team - Timeless

▼Better, Improved Purging processes / Database changes 42 hrs reduced to 32 hrs

▼Staged APPL_TOP – 55 hrs reduced to 42 hrs

▼Serial Install – 55 hrs downtime

Other Considerations

▼Staged APPL_TOP vs. Distributed AD vs. Shared APPL_TOP

▼Keeping current with major releases

▼Merge patches using admrgpch utility

▼Data Management – Purging, Archiving utilities

▼Leveraging AD utilities

▼AutoConfig

▼Patch Timing report

▼Move non-critical patches to outside downtime window

▼Script as many manual steps as possible

▼Close relationship with Oracle Support


Moving forward

▼Periodic scheduled Maintenance

▼Data Management

▼Work with Oracle to test data

▼Move more towards standard Oracle

▼Work collaboratively with Oracle on project plans, key milestones

and go-live dates

▼Engage Critical Care early on (when appropriate)

▼Document and utilize key milestone dates on all escalation requests
