Agenda Background of Project Approach Challenges and Tips –Multiple Environments –Seeded Templates for autoconfig –Moving to Different Systems –11g –Non-RAC to RAC – 11g –Sequence RAC-tax, FND_DUAL

Background of Project Two separate existing general ledger systems (different charts of accounts) to combine Adding Project Accounting Set some standards for E-business suite administration and development Take advantage of linux systems and provisioning new nodes where needed Slender Development, Scalable Deployment Just the technology for this project phase

Installation Versions E-Business Suite R12 RUP6 Database Tools WEB

General Project Plan Create “Gold Copies” –Standard Vision Installation –Standard non-Vision Installation Move to RAC –But keep slender development, test, etc. –Maintain clonability in all directions Move to multiple Application servers

Approach Create Standards for Recreating Steps Create tools for repetitive or error-prone steps

Challenges and Tips Multiple Installation Environments Seeded Templates for autoconfig Moving to Different Systems 11g Topics Non-RAC to RAC – 11g Sequence RAC-tax FND_DUAL

Multiple Installation Environments 10g, Install 11g, 11g, Tools, Web, Cloning Ensuring correct versions of java, perl, unzip, etc..bashrc –PATCH – set to common location for patches and scripts specific to phase –Execute appropriate *.env –Create functions and aliases for common activities pdup – preserve and duplicate a file cdoh – cd to current $ORACLE_HOME cdash – cd to $ADMIN_SCRIPTS_HOME

Seeded Templates for autoconfig $PATH –Autoconfig concatenates what it wants to current –Doesn’t include opatch or adpatch and other utilities Database startup –Starts using pfile which loses dynamic performance parameter settings init.ora errors

Seeded Templates for autoconfig Configuring Templates –Run adtmplreport.sh to get template name and location –Create custom directory –Think of as “site configuration” or “local” –Put modified template in custom directory Survives Cloning Can easily be moved to 11g after upgrade

Seeded Templates for autoconfig Init.ora parameters for 11g –Core_dump_destination All documentation and upgrade wizard says it is deprecated along with background_dump_dest and user_dump_dest to be replaced with diag_destination Actual – Others cause a warning when 11g starts – Core_dump_destination does not – Core_dump_destination defaults to 10g behavior Set it to same location as diag_destination –job_queue_processes Business Event System Event Messages Recommended 2 Change to 10 for better performance of workflow

Moving to Different Systems E-busness Suite uses and a lot for naming things Create templates with and Need for RAC Create tools to establish translation values Create tools to translate the templates for specific database and system

11g Topics Cloning Challenges Native Compile

Cloning Challenges certified for Clone of on database failed if upgraded to jdk 1.6 –adcfgclone.sh fails to make new executables –Known problem at Oracle

Native Compile Much easier in 11g –Stores compiled code in database –Don’t need multiple directories xxx1, xxx2… –Generation of code is much improved Some extra overhead during upgrades Gain performance for production processes –Data access will not improve –E-Business Suite has lots of if..then..else Don’t bother compiling package specifications

Non-RAC to RAC – 11g Clone “Gold Copy” to system with ASM Convert to RAC (single node) Clone additional RAC nodes Clone Application Nodes from “Gold Copy”

Non-RAC to RAC – 11g Prelude to RCONFIG broken as of this writing Slight of hand Clone existing to RAC home destination Move aside and install RAC software Copy appsutil into RAC directory Avoid regenerating init files (diag, etc.)

Sequence RAC-tax Multiple RAC Nodes accessing same blocks Application affinity benefits muted by multiple sequences per block Spreading sequences one per block may help

“Hermitize” sequences, FND_DUAL Especially higher potential win on RAC May be useful for any busy OLTP system FND_DUAL only E-Business Suite
