Client Plug-in Jinitiator Native Sun J2SE 1.5


Oracle RDBMS 10g R2

•Oracle Applications Tablespace Model (OATM)– Objects are classified by object type and access

patterns• Transaction tables,Transaction, indexes,Reference/SEED,Interface,

Summary Management, Archive,NoLogging,Queue,Media,Temporary,Undo, System

– Uniform extents, locally managed, less fragmentation.

Total = 12 Tablespaces (11i: 400+)

•Better Performance– PL/SQL operation 2x faster

– PL/SQL Native Compilation


Application Server Tier (1)

•OracleAS 10g 10.1.2 HOME (Forms & Reports Services) Replaces the 8.0.6-based Oracle Home in 11i

– Updated Swan UI

– Delivers native runtime executables for• Forms (frmweb) (11i: frmwebx)

– Forms Servlet is default deployment / communication mode

– Forms Trace in addition to Forms Runtime Diagnostics (FRD) Record both built-in Forms data and performance data in a single output (profile:

Forms Runtime Parameters)

– FORMS_ environment variables replace FORMS60_

New environment variables e.g. FORMS_TRACE_DIR

– Reports Only available through Concurrent Manager

– Reports Server is not used

– Reports executable rwrun is used directly


Application Server Tier (2)

•OracleAS 10g 10.1.3 HOME Replaces the 8.1.7-based Oracle Home in 11i

– Oracle HTTP Server 10.1.3.0.0 (Apache 1.3.34)

– Oracle Containers for J2EE (OC4J) -3 OC4J instance by default, OC4J instances replace Jserv groups

– Oracle Process Manager and Notification Server (OPMN)• Oracle Notification Server (ONS)

»Delivers notifications between components OHS<->OPMN<->OC4J

• Process Manager (PM)»Start, stop, restart, death detection

• Core (Core logic, parses config files, launch scripts)

– Application Server Control (ASControl)

– modplsql or mod_pls is removed from R12


Relationship Between Two Application Server ORACLE_HOMEs

•All major services are started out of the 10.1.3 ORACLE_HOME.•The Applications modules (packaged in the file formsapp.ear) are deployed intothe OC4J-Forms instance running out of the 10.1.3 ORACLE_HOME, while thefrmweb executable is invoked out of the 10.1.2 ORACLE_HOME.


R12 Patching Enhancement

•Patching R12 Application Oracle Homes– Opatch is used to apply patches to the 10.1.3 and 10.1.2 Oracle Homes.

– Requires access to the Oracle Homes inventory

– List of patches already applied through• Opatch lsinventory – detail

•Application Patching Enhancements– Codelines(12.0:A, 12.1:B) and Codelevels(R12.AD.A.1, R12.AD.A.2)

– Patch prereq checking: only require a codelevel as a prerequisite

– Registering flagged files to understand a patch's impact on customizations

• Replaces the applcust.txt file in 11i• Customized files are now maintained in database format• Display flagged files affected by a patch through impact analysis


R12 Patching Enhancement

– Patch Application Assistant (admsi.pl) • PAA (Patch Application Assistant) is tool/Perl script to generate

customized installation instructions for a patch in Oracle Applications R12 which helps user to track and perform manual steps during patching.

» CLI or GUI

» $AD_TOP/bin/admsi.pl

» perl $AD_TOP/bin/admsi.pl –cli

– Patch Wizard functionality improvement

– Easy to identify applied patch, file history and patch timing and action summary

Patch Impact Analysis Summary


R12 Cloning

•Cloning is much easier – Unified APPL_TOP

• In 11i , APPL_TOP have its different name and files in each APPL_TOP will depend on type of Node. Starting from R12, it will use Unified APPL_TOP which means all files required for all middle tier services are included in all nodes of Multi Node installation

»Multi-node to single node, no need to merge APPL_TOP

»Multi-node to multi-node, only one APPL_TOP copy is needed

»Choose or switch services on each node easily.»All nodes will have Y against all services (For multi Node) in FND_NODES table.

•Rapid clone supports RAC and grid computing – RAC support is extended to support ASM as well as features to

expand an existing RAC system by adding a node to an existing RAC cluster.


11i Apps file system Layout


R12 Apps file system Layout


Instance Top (New)

•Instance home structure /<BASE>/inst/<context_name> ($INST_TOP)

$INST_TOP/admin/scripts ($ADMIN_SCRIPTS_HOME) (11i, $COMMON_TOP/admin/scripts)

$INST_TOP/appl ($APPL_CONFIG_HOME) context file is under $INST_TOP/appl/admin

11i : $APPL_TOP/admin

$INST_TOP/fnd/12.0.0/secure ($FND_SECURE)$INST_TOP/certs$INST_TOP/logs ($LOG_HOME – autoconfig writes logs here by default)$INST_TOP/ora ($ORA_CONFIG_HOME)$INST_TOP/ora/10.1.2 ($ORACLE_CONFIG_HOME) )$INST_TOP/ora/10.1.3 $INST_TOP/pids$INST_TOP/portal


Benefits of New Layout

•Clear distinction between the location of data, code, and configuration files.

•Configuration and log files are centrally contained in the instance configuration home

•Ability to share code (Applications, Technology Stack) among multiple instances.

•Collection of configuration, logs is much easier since they are centrally located.

•Can split ownership of apps and technology stack file systems.

•Ability to place the configuration home on a Network or a local file system for performance improvement.


Additional New Feature in R12

• Rapid install– Store Base Configuration in Database

• No need to copy config.txt

– Multiple Domain Support for Database and Middle Tier• Rapid Install supports deploying the database node and the middle tier node into different

domains.

– Shared File System Support• Rapid install allows you to select if app servers are using shared appl_top

• No hardcode apps password on unix file system– FNDCPASS Utility New Feature: Enhance Security With Non-

Reversible Hash Password (enhance FND_USER password security)

• Improved Forgot password feature– Retrieve user_name and password

– no workflow inbound process needed


Login Assistance


Performance Monitor

The performance dashboard now shows RAC cluster info.

Challenges in R12

•Configuration files

•Log files

•Miscellaneous challenges

•Prepare custom codes if upgrade to R12


Configuration Files (1)

• <apps_base>/inst/apps/<context_name>/ora/10.1.3

– <context_name>.env

– /Apache/Apache/conf

• apps.conf, httpd.conf, oracle_apache.conf, ssl.conf

• dms.conf, mod_oc4j.conf, security.conf, url_fw.conf

– /config

• ias.properties (used by EM agent)

– /opmn/conf/opmn.xml– /j2ee/oacore/config

• applications.xml, default-web-site.xml, global-web-application.xml

• j2ee-logging.xml, jms.xml, oc4j-connectors.xml, oc4j.properties,

– /j2ee/oacore /application-deployments/oacore/html

• orion-web.xml


Configuration Files (2)

Jserv.conf & Jserv.properties in 11i are replaced with

• Oc4j.properties : defines basic Apps directory aliasing

• Server.xml : defines J2EE applications and their shared libraries for runtime OC4J and points to other XML configuration files (rmi.xml,jms.xml, application.xml, global-web-application.xml, default-web-site.xml and etc)

• Orion-application.xml : defines location of Java classes of all J2EE web modules deployed under J2EE application

• Orion-web.xml : defines servlet level parameters for J2EE web modules

Miscellaneous Challenges

•R12 Cloning considerations– Dependency on AutoConfig as a post step to everything - increased downtime

might be needed.

– Problems with standard cp command in both Solaris (cp -Rh) and HP-UX(cp -R) (Cloning)

• 603104.1 Troubleshooting RapidClone issues with Oracle Applications R12

• Note:406982.1 Cloning Oracle Applications Release 12 with Rapid Clone

• 6776948 : R12 RAPIDCLONE CONSOLIDATED FIXES JUL/2008

•Problem with starting web services if web server crashed– Need start, stop,start

– Delete the lock file under persistence folder• $ORA_CONFIG_HOME/10.1.3/j2ee/forms/persistence/forms_default_group_1/jms.state.lock,

$ORA_CONFIG_HOME/10.1.3/j2ee/oacore/persistence/oacore_default_group_1/jms.state.lock

$ORA_CONFIG_HOME/10.1.3/j2ee/oafm/persistence/oafm_default_group_1/jms.state.lock


Preparing Custom Development if Upgrade to R12

• Mod_plsql If you have custom development on mod_plsql, you should migrate your Web pages to Oracle

Application Framework • Oracle Reports Server Reports

– Convert the reports to Oracle XML Publisher (some automated tools are available to help you)

– Convert the reports to Oracle Application Framework ( no automate tool to help you)

– Run the reports through the Concurrent Manager (rewrite any charts using the Oracle Reports Charting tool (BI Chart Bean), this method will not be supported in Oracle

Fusion Applications) • Oracle Graphics Integrations with Oracle Forms

– Convert both the form and the chart to an Oracle Application Framework-based application.

– Convert the chart to an Oracle Application Framework-based page that can be launched from Oracle Forms. (it will not be supported in Oracle Fusion Applications )

Oracle RAC

Product Data Hub - R12 RAC Implementation

SOA/AIA ERP(11.5.9)


R12 RAC Implementation

• Fresh installed of R12 as multi-nodes

• Applied R12 RUP4 (RUP6 is available)

• Upgrade database to 10.2.0.4 and applied DST v7 patch – Note:454750.1 Oracle Apps Release 12 with Oracle Database 10.2.0 interoperability notes

• Upgrade tech stack 10.1.3.3– Note 454811.1 Upgrading Oracle E-Business Suite Release 12 10.1.3 Oracle Home to

Oracle 10gAS Patch Set 3 (10.1.3.3)

• Upgrade tech stack to 10.1.2.2.2– Note:437878.1 Upgrading Forms and Reports 10g in Oracle Applications Release 12

• Upgrade JDK to 1.6– Note 455492.1 Using Latest Update of Java 6.0 with Oracle E-Business Suite Release 12

• Convert database to 2-node RAC– Note:388577.1 Using Oracle 10g Release 2 Real Application Clusters and Automatic

Storage Management with Oracle E-Business Suite Release 12

• Setup PCP

• Setup load balance on web servers– Note:727171.1 Implementing Load Balancing On Oracle E-Business Suite - Documentation

For Specific Load Balancer Hardware

– Note 380489.1 Using Load-Balancers with Oracle E-Business Suite Release 12


Lesson Learned

1. Hostname on concurrent manager tier can not exceed 30 character

– FND_CONCURRENT_QUEUES

– TARGET_NODE VARCHAR2(30)

2. Check if /etc/hosts has correct entry– 155.64.164.112 tus1mdmdbssin01.ges.symantec.com

tus1mdmdbssin01

3. VM or Physical server ?

4. Firewall between application nodes ?– Java object cache port need opened

– s_java_object_cache_port need to be set

– s_fnd_jdbc_usable_check set to true


Lesson Learned

5. Bug in adpatch

6. Enable automatic compilation of JSP pages in R12

In Release 12 the (automatic) compilation of JSP is disabled and on runtime only the pre-compiled JSP's are picked up (change justrun to recompile)

<jsp_debug_parameters oa_var="s_jsp_main_mode">recompile</jsp_debug_parameters> $INST_TOP/ora/10.1.3/j2ee/oacore/application-deployments/oacore/html/orion-web.xml <init-param> <param-name>main_mode</param-name> <param-value>recompile</param-value> </init-param>

7. Custom top

– You can define your custom top in the context file. So all the configure files will have your custom top info


Lesson Learned

9. Bug in R12 on RAC– jdbc connection is not using the service_name

– ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

10. Avoid timeout issue?– load balancer persistence or stikiness should be set to session cookie

– check s_oc4j_sesstimeout and s_sesstimeout• $ORA_CONFIG_HOME/10.1.3/j2ee/oacore/application-deployments/oacore/html/orion-

web.xml

11. Using NAS for shared APPL_TOP?– $INST_TOP on local disk to avoid performance issue

12. Gather system stats for CPU and IO– execute DBMS_STATS.CREATE_STAT_TABLE ('SYS','OLTP_stats');

– execute DBMS_STATS.GATHER_SYSTEM_STATS (gathering_mode => 'INTERVAL', interval => 60, stattab => 'OLTP_stats', statid => 'OLTP');

– select * from aux_stats$


Summary
