– Dell IT: Implemented Oracle Applications on RAC– 11+ Years of Oracle DBA/Oracle Applications DBA– Dell Database Solutions Engineering:
Integrating, validating, bundling, and sustaining Dell’s Oracle DB and RAC solutions, based on PE servers, and Dell | EMC storage.

Implementation: Environment
• Hardware:– Application Tier: Dell PowerEdge servers– Database Tier: Dell PowerEdge servers– Interconnect: 2 Private 2 Gigabit switches– Storage: EMC storage for database
NAS storage for shared files system• Software:
– Red Hat Linux AS 3.0 (kernel 2.4.21-4EL or higher)– Oracle Applications 11.5.10 with CU2– Oracle Database 10g R1(10.1.0.5)

Fresh Install
10.1.0.3 DB/CRS
Implementation: Steps
Fresh Install• Use Shared File System • Rapid Install • Post Installation Tasks
10g Install • Install CRS • Install Database Software
Install Components • Install Database Components
10.1.0.5 Upgrade • Upgrade CRS to 10.1.0.5• Upgrade DB to 10.1.0.5
Implementation: Steps Continued
DB 10g Upgrade• DB Upgrade Assistant • Post Upgrade Steps
Autoconfig • Copy oui22 to 10g • Run adbldmxml.sh
ASM Migration• Create ASM Instances • Create Diskgroups • Data Files Conversion
Convert to RAC • Autoconfig on Apps Tier • Generate appsutil.zip • Autoconfig on DB tier
Implementation: Steps
Convert to RAC (continued)
• Run adcfgpreclone.pl • Run adcfgclone.pl • Configure Listeners/tns
Establishment for RAC
• Autoconfig on Apps Tier • Load Balance for DB
PCP Configuration• Setup PCP • Setup Transaction Mgr • Load Balancing of PCP
Issues/Solutions • Listener/TNS Configure • Diskgroup vs. adcfgclone
Cloning
• Why Clone?– Create new DEV/QA environment – Refresh DEV/QA environment from production– Migrate an existing system to new hardware
• Clone Steps: – Use Rapid clone technology – Latest Rapid Clone patches required – Clone Database Tier– Clone Applications Tier– Post Clone steps

1. Prepare source system: adpreclone
2. Copy application file system
3. Configure Target system
4. Enable shared Appl_TOP
Cloning
• Post Clone Steps– Purge old Concurrent request– Clean up logs and out files – Update profiles– Update FND tables
• Migration Requirement– Source: 11.5.10 on 9i RAC– Target : 11.5.10 on 10g RAC/ASM– On same OS (Red Hat Linux)
• Challenges– Minimize Downtime for source production – Migrate to new servers and new storage
• Solution Design– Build standby database to reduce downtime – Clone Application Tier to target by Rapid Clone– Clone database from source to target
Migration
Source : 11.5.10/9iRACPrepare source: adpreclone appstierClone Applications Tier
Apps Servers
Target: 11.5.10, 10g RAC/ASM
Step 1: Clone Applications Tier (optional) and copy 9i Oracle Home
Migration: 9i RAC to 10g RAC/ASM

Migration: 9i RAC to 10g RAC/ASM
Step 4: Activate Standby DB
Actions:
• Make sure no redo log gap
• Shutdown source environment
• Finish managed recovery
• Switchover standby DB to primary

Migration: 9i RAC to 10g RAC/ASM
Step 5: Upgrade 9i DB to 10g
Actions:
• Run Database Upgrade Assistant: DBUA
• Add SYSAUX Tablespace
• Run library update, configure 10g listener
• Post Upgrade Steps: copy oui22, compute
Statistics, cr9idata.pl, adblxml.sh, etc
• Autoconfig on 10g Oracle Home
